Dear Readers, the Vol. 9 No. 1 issue of <strong>SEAMIC</strong><br />

EDITORIAL<br />

NOTE<br />

Newsletter is dedicated to publishing the mineral<br />

resources potential of <strong>SEAMIC</strong> member States<br />

constituting Ethiopia, Kenya and Mozambique in an effort to introduce and promote<br />

their mineral wealth. In subsequent Newsletters the mineral potentials for the<br />

remaining Southern and Eastern African Mineral Centre (<strong>SEAMIC</strong>) member States<br />

will be addressed. In light of the above the mineral potentials of the three member<br />

States may be summarized as follows.<br />

Mozambique has a huge mineral potential that is largely untapped. Gold has been<br />

produced from the Greenstone belt and the alluvial deposits. Tantalum-niobium,<br />

other rare metals and semi-precious stones are abundant. Deposits of heavy mineral<br />

sands and a wide range of industrial minerals comprise a few of the mineral wealth in<br />

Mozambique that are under development. The government’s effort to increase the<br />

geological knowledge base through exploration for a wide range of minerals that was<br />

curtailed for a number of years in the 1980s due to the civil war in the country is now<br />

being aggressively carried out and is assisting speedy geological data collection and<br />

dissemination. This effort has significantly enabled the mineral sector development<br />

in the country and as a result many mining projects have been initiated.<br />

The earth resources of Kenya include a wide range of minerals, both metallic and<br />

industrial, as well as varieties of gemstones. The mineralisation of gold copper, silver,<br />

kyanite, corundum, graphite, wollastonite, marble, asbestos, flourspar, magnesite,<br />

kaoline, variety of gemstones, gypsum, clay, diatomite, and rare-earth elements are the<br />

few to mention. There are several exploration and mining activities underway in the<br />

country including exploration for gold and heavy mineral sand.<br />

Ethiopia is endowed with abundant mineral resources associated with the<br />

Precambrian, Paleozoic-Mesozoic sedimentary rocks, the Cenozoic volcanic and<br />

sedimentary rocks. Currently metallic minerals such as gold, columbo-tantalite and<br />

alluvial platinum and a variety of industrial minerals such as kaolin, opal, dolomite,<br />

quartz, feldspar, soda ash, dimension stones and cement mineral raw materials are<br />

produced. Rich deposits of potash, manganese and rock salt are abundant in the<br />

Tertiary/Quaternary sediments. Natural gas, geothermal energy and coal deposits<br />

have been explored at feasibility levels and are awaiting development.<br />

For more details the reader is invited to the articles presented in this Newsletter on<br />

the geology and mineral potential of Ethiopia, Kenya and Mozambique.


GEOLOGY <strong>AND</strong> <strong>MINERAL</strong><br />

RESOURCES OF ETHIOPIA<br />

BY GEOLOGICAL SURVEY OF ETHIOPIA<br />

INTRODUCTION<br />

Systematic mineral exploration in the country started in the 1970’s leading to the discovery of<br />

many metallic mineral deposits (example, gold and tantalum) and industrial raw materials for<br />

manufacturing of cement, ceramics, glass, fertilizer, etc. Exploration for fuel (natural gas and<br />

oil) and energy (coal and geothermal energy) occurrences has been conducted back in the late<br />

1940s and are still under investigation. Little is known to date about the occurrences of gem<br />

minerals, but prospecting is underway by the private sector.<br />

Systematic exploration and mining development so far undertaken in the country indicate the<br />

low-grade volcano-sedimentary assemblages as the main host rocks for precious, base, rare and<br />

ferrous and ferroalloy metals. The distribution of industrial minerals and rocks is mainly related<br />

to Precambrian metamorphic rocks, Paleozoic-Mesozoic sedimentary rocks, and Cenozoic<br />

volcanic and sedimentary rocks.<br />

Currently, mining companies are engaged in the exploration for further gold and base metal<br />

occurrences in different regions of the country. There are also several local and foreign private<br />

companies mining marble, granite, amphibolite, opal and limestone in various parts of the<br />

country. Efforts are also being made to develop the geothermal and gas energy resources.<br />

GEOLOGY<br />

The Geology of Ethiopia can be grouped into three major stratigraphic units, namely: the<br />

Precambrian basement rocks, Late Paleozoic to Mesozoic sedimentary rocks and Cenozoic<br />

volcanic and sedimentary rocks, and Tertiary/Quaternary volcanics and sediments.<br />

The Precambrian basement rocks are poly-deformed and metamorphosed high grade gneisses<br />

and schists associated with low-grade meta-volcano-sedimentary rocks. They are mainly<br />

exposed in the northern, western and southern parts of the country.<br />

Late Paleozoic-Mesozoic sedimentary rocks are widely distributed in the northern, central,<br />

eastern and southeastern parts of the country. The sedimentary rocks are unconformly overlying<br />

the basement rocks and mainly composed of sandstone and limestone and are exposed<br />

mainly in the Ogaden, Abbay and Mekele Basins. Phanerozoic sedimentary and volcanic<br />

rocks cover much of the country’s central highlands, rift valley and eastern lowlands.<br />

The Tertiary to Quaternary volcanics are associated with the evolution of the East African Rift<br />

System. The main rock types are basalts, trachytes and associated dyke swarms, andesites, rhyolites,<br />

ignimbrites and pumiceous ash.<br />

Tertiary sedimentary rocks are known in the Ogaden, in the Danakil Depression, and in the<br />

lower Omo River Valley. These rocks consist of sandstone, limestone, conglomerate, mudstone<br />

and shale. Rich deposits of potash, manganese, rock salt and other types of evaporites<br />

are abundant in the Tertiary/Quaternary sediments. Quaternary sediments occur throughout<br />

the country and were formed as lacustrine as well as marine formations. They comprise limestones,<br />

clay, siltstone, sand, volcanoclastic, and others.<br />

<strong>MINERAL</strong> RESOURCES<br />

Metallic Minerals<br />

Exploration and mining development activities so far undertaken in the country show the lowgrade<br />

volcano-sedimentary assemblages as the main host rock for precious, base, rare and ferrous<br />

and ferroalloy metals. Three low-grade volcano-sedimentary domains and the associated<br />

intrusives of the Arabian Nubian shield occur in southern, western and northern Ethiopia.<br />

a) Southern domain (Adola and Kenticha belts): This domain consists of the primary gold of<br />

Lege Dembi, Sakaro, Wollena, Kumuda, Megado-Serdo, Dawa-Digati, Moyale and Ababa<br />

River; the columbo-tantalite of Kenticha and Meleka and the Adola Nickel deposit.<br />

b) Western domain (Dul-Nazila, Menghi-Gizen, Fakusho-Oda and Akobo-Yubdo-Baruda<br />

belts): These belts host the primary gold of Dul, Oda-Godere, Chamo (Akobo), Baruda,<br />

Bekoji-Motish and Kilaj; Yubdo Platinum; base metals of Azali-Akendeyu, Abetselo and<br />

Kata; Fakusho molybdenite; and the iron deposits of Bikilal, Chago, Gordana and Koree.<br />

c) Northern domain (Tigray Greenstone Region and Ethiopian Rift Zone (Danakil<br />

Depression): Mafic ultramafic belts comprise the primary gold occurrences of Terakemti,<br />

Adi Zeresenay, Zager and Niraque, as well as the base metals of Tsehafi Emba.<br />

Besides these known deposits and occurrences, there exists a number of virgin exploration targets<br />

in the Precambrian terrains of southwest (Akobo belt extension), eastern (Soka series), the<br />

Melka Arba iron ore within high grade metamorphic terrain, the Chercher Malachite in the<br />

Mesozoic sandstone formations, and the Enkafela manganese in the Plio-Pleistocene conglomerate<br />

and gypsifecous units of the Danakil Formation.<br />

2


Industrial Minerals and Rocks<br />

Industrial minerals and rocks are mainly related to Precambrian metamorphic rocks, Paleozoic-<br />

Mesozoic sedimentary rocks, and Cenozoic volcanic and sedimentary rocks. These categories<br />

can be considered as a distinct domain containing a characteristics and predictable suite of<br />

industrial minerals and rocks.<br />

• The Precambrian basement domain predominantly composed of high and low grade rocks.<br />

The high-grade rocks including granites, gneissose rocks and associated pegmatites consists<br />

of Kyanite, Asbestos, feldspar, mica, kaolin, quartz, beryl and spodumene. The meta-sedimentary<br />

sequences commonly host graphite, talc, serpentinites, peridotite, and marble. The<br />

basement rocks also provide hard rocks suitable for use as blocks or in crushed form as sized<br />

coarse aggregate for construction.<br />

• The Paleozoic-Mesozoic sedimentary successions host limestone, sandstone, shale, marl<br />

and gypsum and provide significant raw materials for cement, glass and construction industries.<br />

• The Cenozoic Volcanic Rocks comprises basalts, trachytes, andesites, rhyolites, ignimbrites,<br />

pumice and scoria. The Cenozoic sediments include limestone, sandstone, conglomerate,<br />

mudstone, shale, gypsum, anhydrite, clay, siltstone, volcanoclastics and other types of evaporates.<br />

The economic importance of the Cenozoic rocks as industrial mineral resources is<br />

demonstrated by the presence of various construction materials, potash, common salt, gypsum,<br />

bentonite, diatomite, pumice, volcanogenic sulphur, etc.<br />

Energy Minerals<br />

• The sediments in Tigray in the north and in the Gambela area in the west are of potential<br />

areas for oil and gas prospects in Ethiopia and exploration for these minerals is ongoing. In<br />

the Ogaden Basin in eastern Ethiopia, past explorations indicated occurrences of oil and<br />

gas. A gas deposit of commercial value has been discovered in Calub that is at the moment<br />

under development.<br />

• There are many occurrences of coal of different ranks in different parts of the country within<br />

the sediments intercalated in the Tertiary volcanic rocks. The Yayu lignite coal deposit<br />

in southwestern Ethiopia has been studied at a feasibility level and it is under developmental<br />

stage.<br />

• The Main Ethiopian Rift and the Afar Depression are closely associated to Tertiary to<br />

recent volcanic activities. An enormous amount of geothermal energy is estimated to exist<br />

within the Rift. Pilot exploration drillings have proven the existence of steam capable of<br />

generating geothermal power in Langano and Tendaho areas in the central and northern<br />

parts of the Rift respectively.<br />

CURRENT MINING STATUS IN ETHIOPIA<br />

Gold<br />

The Lege Dembi gold mine is the only modern primary gold mine existing in the country. It<br />

is located 7 km southwest of Shakiso, a mining town about 500 km south of Addis Abeba, and<br />

is subdivided into the northern, Central and southern ore bodies. The gold is hosted in auriferous<br />

quartz veins associated with north-south trending shear zones that separate low grade<br />

rocks from high grade gneisses. The deposit has a proven reserve of 83 tons of gold at an average<br />

grade of 4 g/t.<br />

Columbo–tantalite<br />

This mine is operated by a state-owned company, Ethiopia Mineral Development Share<br />

Company (EMD), at Kenticha, about 50 km southeast of Shakiso in the Adola Greenstone<br />

Belt. A deposit in weathered crust was delineated in 1988 with proven reserves of 25,850 tons<br />

of columbo– tantalite ore at 0.02 to 0.03% Ta 2O 5. Currently, a pilot plant is producing 60<br />

tons/year of columbo–tantalite ore.<br />

3


Kaolin<br />

Kaolin is mined by EMD Share Company at Bombawha in Southern Ethiopia, about 430 km<br />

from Addis Abeba. This Kaolin is a product of in situ weathering of pegmatites and granites.<br />

The upper parts of the pegmatites and granites have been kaolinzed to a depth of 20mt. Proven<br />

reserves of 150,000 ton of kaolin had been identified in 1992, at which time open-pit mining<br />

operations began. The main consumers of its products are the Tabor Ceramics and Aluminum<br />

Sulphate Industries. The quality of the product satisfies its customers with an average Fe 2O 3<br />

content of 0.7 - 0.8%. The grade of Kaolin is 32 - 36% with a recovery of 96%. The final product<br />

has a grain size of less than 45 micrometer.<br />

Dolomite<br />

The Kenticha dolomite marble occurs north-west of the tantalum mine and extends for several<br />

kilometers in a north-south direction. The composition of the marble varies from calcite to<br />

magnesite and the grain size varies from fine to coarse. The Ethiopia Mineral Development<br />

Share Company sells its products to Modern Building Industry (MBI), a Saudi enterprise, after<br />

reducing its size to 0.1-0.3 mm by crushing. The final product is used as filler in paint, paper,<br />

and rubber industries and marketed locally and abroad. The annual production is 5,000 tons<br />

and the resource is about 1.5 million tons.<br />

Quartz and Feldspar<br />

Quartz and feldspar at Kenticha are mined as by-products of tantalum mining to be used for<br />

different applications. These industrial mineral products are consumed mainly by Tabor<br />

Ceramic Factory. The annual production is about 6,000 ton from a combined resource of one<br />

million tons.<br />

Soda Ash<br />

The Soda Ash Mine is located at Lake Abiyata in the Rift valley, about 200 km from Addis<br />

Ababa. The resource at Lake Abiyata and the neighboring lakes of Shalla and Chitu exceed<br />

460 mt of sodium carbonate at salt concentrations ranging from 1.1 to 1.9%. The plant produces<br />

about 20,000 ton/year of Soda Ash using solar evaporation harvesting system on a semiindustrial<br />

scale. The products are consumed by Caustic Soda, soap and detergent manufacturers<br />

as well as by water supply institutions.<br />

Opal<br />

Mining for opal has been going on since 1998 after exploration commenced in 1994 in the central<br />

part of the country by the private sector. Systematic exploration is underway to define bigger<br />

deposits and to look for better quality gems.<br />

Dimension Stones<br />

According to the US Geological Survey mining statistics, the production of dimension-stone<br />

in Ethiopia reached 100,000 tons in 1999 – an increase by 150% from 1995. This includes the<br />

production of granite, marble and limestone. The large increase in production was boosted by<br />

strong construction activity in the country. At present, there are several producing local and<br />

foreign private companies in Ethiopia. The National Mining Corporation (NMC), Saba<br />

Stones and Ethiopian Mining Industry (EMI) are mining marble, granite, and amphibolite and<br />

limestone in various part of the country. In addition to the local market, some of them are<br />

exporting the marble blocks to the Middle East and Europe.<br />

THE GEOLOGY <strong>AND</strong> <strong>MINERAL</strong><br />

RESOURCE POTENTIAL OF KENYA<br />

BY MINES <strong>AND</strong> GEOLOGICAL DEPARTMENT OF KENYA<br />

GEOLOGY<br />

Geological Overview<br />

The geology of Kenya may generally be grouped into the following five major geological<br />

successions: Archean (Nyanzian and Kavirondian), Proterozoic (Mozambique Belt and<br />

Bukoban) Palaeozoic/Mesozoic sediments, Tertiary/Quaternary volcanics and<br />

Tertiary/Quaternary sediments<br />

Quaternary: Soils, alluvial beach sands, evaporates, fossil coral reefs and sandstones<br />

at the coast: alluvial and lacustrine sediments of the Rift<br />

Valley. There are also volcanic rocks of the rift valley from the<br />

younger volcanoes.<br />

Tertiary: Coastal sediments, Late Miocene and Pliocene volcanics,<br />

Terrestrial and lacustrine inland sediments. There are Early<br />

Tertiary formations not represented at surface.<br />

Palaeozoic/Mesozoic: (Cretaceous, Jurassic, Triassic, Permian and Carboniferous): The<br />

Karroo formations of the coastal hinterland, including the basal<br />

sedimentary formation in north-east Kenya.<br />

Proterozoic: Kisii series (Bukoban system): Volcanics with sediments<br />

Mozambique Belt: quartzites, biotite/hornblende gneisses,<br />

schist, granitoid gneisses, amphibolites, migmatites.<br />

Intrusives: syntectonic granites<br />

Archean: Kavirondian system: Mudstones, Sandstones, Conglomerates,<br />

Granitic intrusions<br />

1. The Nyanzian Shield<br />

Nyanzian system: Shales, cherts, ironstones, Pyroclastics,<br />

Rhyolites, Andesites, Basalts.<br />

The Nyanzian and Kavirondian systems forming the Nyanza Craton are the oldest rocks<br />

in the country with ages over 2,500 million years.<br />

The Nyanzian system is mainly composed of lavas and pyroclastics with minor sediments<br />

and banded ironstones. The Kavirondian, which rests unconformly on the Nyanzian, consists<br />

of grits, sandstones, greywackes and conglomerates. Both the Nyanzian and<br />

Kavirondian systems are isoclinally folded about axes that have an east-westerly trend.<br />

5


Kavirondian, is only slightly younger than Nyanzian but folding in the two systems has<br />

similar orientation. Numerous granitic bosses and batholiths have intruded the Nyanzian<br />

and Kavirondian. The Kavirondian intrusions were more but the pre-Kavirondian were<br />

also widespread and the two systems are discernible.<br />

2. Mozambique Belt<br />

The Mozambique belt is a structural unit within which a wide variety of meta-sedimentary<br />

and meta-igneous rocks are found showing a broad concordance of structural style and<br />

metamorphic history. In most of these rocks, the degree of deformation is intense and is<br />

of high metamorphic grades. They were thus referred to earlier in literature as the basement<br />

system rocks, due to high degree of metamorphism and deformation.<br />

Recent work on the Mozambique Belt has shown that rocks can be sub-divided into<br />

groups of contrasting lithology, structure and composition of igneous rocks content. These<br />

groups are being studied in greater detail in order to come up with proper chronostratigraphic<br />

terminology.<br />

Within the Mozambique Belt basic igneous complexes are found and range in size from<br />

bosses to small dykes. They occur both east and west of the Rift Valley. Some of the older<br />

basic intrusions have undergone deformation and metamorphism to give ortho-amphibolites<br />

and charnockitic gneisses.<br />

Basic and granitic intrusions are known in the Mozambique Belt. The most characteristic<br />

feature of the Mozambique Belt is its structural trend which is more or less north-south in<br />

its entire belt.<br />

Variations of the northerly trend are minor and, when observed, can be explained and are<br />

localised. The majority of Mozambique Belt rocks have been placed in upper Precambrian<br />

(Proterozoic).<br />

3. Palaeozoic and Mesozoic Formations<br />

Palaeozoic and Mesozoic formations in Kenya are found near the coast and in north-eastern<br />

Kenya. The earliest of these rocks are Permo-Carboniferous which are mostly sandstones<br />

and shales that form the Duruma series. This is equivalent to the Karroo system in<br />

Southern Africa. The local formations are Taru; Maji-ya-Chumvi; Mariakani and the<br />

Mazeras. They extend for about 100 kilometres from Taru to Mazeras, west of Mombasa.<br />

The rocks dip very gently towards the ocean and are heavily faulted in places.<br />

Mesozoic rocks occur in two separate areas, in the north-east part of Kenya and along the<br />

Coast belt. The stratigraphy and fossils in the two areas are very distinct and it is likely<br />

that the sedimentary basins in the two areas were connected. Revision mapping in the area<br />

has come up with interesting lithological units that have revised lithological names.<br />

4. Tertiary and Quaternary Volcanics<br />

Volcanic rocks cover the central parts of the country from south to north, occurring in the<br />

floor of the Rift Valley and on the peneplains west and east of the valley.<br />

The oldest of the volcanics are of Lower Miocene age and comprise the eroded lavas and<br />

pyroclastic piles of South Nyanza. Late in Miocene times, Kapiti and Yatta phonolites<br />

were erupted and flowed to great lengths.<br />

6


Further eruptions accompanied by faulting persisted and also gave rise to the Rift Valley<br />

and the volcanic piles of Mounts Kenya, Elgon and Kilimanjaro.<br />

Quaternary volcanism was mostly within the Rift Valley and has given rise to the craters<br />

and cider cones that are found in the floor of the valley e.g. Longonot, Menengai and<br />

Suswa.<br />

7


5. Tertiary and Quaternary Sediments<br />

There are many deposits of sediments in various parts of Kenya. They usually occur at the<br />

base of volcanic succession, intercalated with it or occurring in tectonic troughs.<br />

The repeated faulting of the Rift Valley floor and the numerous volcanic eruptions created<br />

many short-lived basins of internal drainage in which lacustrine and fluviatile sediments<br />

accumulated. Most of these sediments are unfossiliferous, but a few are of interest as they<br />

contain deposits that bear artefacts and interesting fossils that have been studied extensively.<br />

The more important sediments of middle Pleistocene are the Olorgesaillie lake beds, a<br />

lacustrine series with much diatomite, mammalian fossils and artefacts. This is also comparable<br />

to the Kariandusi sediments near Gilgil and the Kanjera Beds in the Kavirondo<br />

Gulf off Lake Victoria. Olorgesaillie beds and Kariandusi sediments are in the Rift Valley.<br />

<strong>MINERAL</strong> OCCURRENCE<br />

A wide range of minerals, both metallic and non-metallic (industrial), are known to occur<br />

in the country. These include barite, gypsum, gold, silver, lead, talc, titanium, salt, a variety<br />

of gemstones, (mainly ruby and several varieties of garnet) dimension stones, silica<br />

sand, heavy mineral sands, manganese, zinc, wollastonite, graphite, kaolin, copper, nickel,<br />

chromite, pyrite, various clays, rare earth elements and pyrochlore.<br />

The Geological environments for the mineralization can be summarised as follows:<br />

(a) The Archean Nyanzian Craton area of Western Kenya where metallic mineralization<br />

of base and precious metals are known to occur: gold, copper and silver have been<br />

mined in the past. They are also potential for ferrous and no-ferrous metals.<br />

Kimberlitic bodies have also been reported.<br />

(b) The Proterozoic Mozambique Belt that is most extensive in Central Kenya north to<br />

South in which minerals such as kyanite, corundum, graphite, wollastonite, marble,<br />

asbestos, fluorspar, magnesite, kaolin and a variety of gemstones are found together<br />

with minerals associated with basic and granitic rocks.<br />

(c) The sedimentary rocks of Palaeozoic to Quaternary are widespread. These rocks are<br />

sources and hosts of limestones, gypsum, clays, manganese and construction materials<br />

and possibly hydrocarbons. Base metal mineralization, lead-zinc-barite and copper<br />

are known to occur in the sedimentary basin along the coastal belt.<br />

Heavy mineral sands also occur along the coastal beach sands and recently deposits of<br />

about 3.2 billion tons of titanium bearing have been discovered.<br />

(d) The volcanic rocks associated with Rift System host a variety of minerals and construction<br />

materials. The volcano-sedimentary accumulations have deposits of clays,<br />

evaporites, trona (soda ash), diatomite, natural carbon dioxide, kunkar and gypsum.<br />

Gem quality rubies have also been discovered recently.<br />

8<br />

The geothermal fields are found in the area and some have been exploited, currently<br />

producing 57 MW of power to the national grid.


Carbonatites are known to be host of several minerals found in the Nyanzian shield<br />

area, around Lake Victoria shores and in the southern part of the coastal sedimentary<br />

basin. Mrima, one of the carbonatites known for potential of niobium and rare<br />

earth elements (REE) is found in the coastal basin, south of Mombasa.<br />

CURRENT ACTIVITIES<br />

Exploration<br />

A number of international companies, including, Tiomin, AfriOre and Kansai/Mid-<br />

Migori are currently carrying out exploration activities for gold. Tiomin Resources Inc. has<br />

recently completed exploration for heavy mineral sands and has been issued with a Mining<br />

Lease. A fiscal agreement providing for incentives has also been signed.<br />

Mining<br />

The Kenya Mining industry is dominated by production of non-metallic minerals which<br />

are mainly: soda ash (trona), fluorspar, diatomite, vermiculite, natural carbon dioxide,<br />

kaolin, barytes, a variety of gemstones, limestone and lime products including various construction<br />

materials.<br />

In the case of metallic minerals, some quantities of gold are being produced. Iron ore is<br />

produced from localised small deposits and is utilised in the manufacture of cement in the<br />

country.<br />

Production of some minerals during 2000-2005 was as follows:<br />

Mineral Products<br />

*Export figures ** Provisional<br />

Soda ash is produced from the mineral trona that occurs at Lake Magadi which is situated<br />

within the Great Rift Valley. The commodity is produced by the Magadi Soda<br />

Company Limited in one of the biggest known natural sources of trona in the world. The<br />

bulk of the soda ash is exported but a good deal of the commodity is used in various local<br />

industries as well. The annual production during the year 2005 was valued at US$ 38million.<br />

Trona occurs together with common salt and Lake Magadi is also a major source of crude<br />

salt.<br />

9


Fluorspar is mined to the east of the town of Eldoret within the Rift Valley system. The<br />

Kenya Fluorspar Company Limited operates the mine. The mine produces acid grade<br />

Fluorspar of which the bulk is for export.The annual production for the year 2005 was valued<br />

at US$ 14million.<br />

Diatomite is produced at Gilgil within the Rift Valley, but it is also known to occur in a<br />

number of localities within the Rift Valley system. The commodity is produced for both<br />

export and local markets. Its potential is large.<br />

Vermiculite is produced from Lodosoit which is in the northern central part of the Rift<br />

Valley Province within the pre-Cambrian rocks of Mozambique belt.<br />

Limestone and lime products are produced for the manufacture of cement and other industrial<br />

products. Cement and construction industries take the bulk of the limestone mined<br />

and quarried. Limestone, marbles and dolomites are widely occurring in the country and<br />

a large tonnage of the commodity is known to exist. Along the coastal belt, Bamburi<br />

Portland Cement Company Limited exploits kunkar and crystalline limestone in the vicinity.<br />

The three cement factories, Athi River, Bamburi and East Africa Portland produce over<br />

1.5 million tonnes of cement to meet local needs.<br />

Natural Carbon dioxide associated with the rift system, is exploited in a number of places<br />

and has been marketed by Carbacid (CO 2 Mfg) Limited for industrial purposes. Other<br />

Industrial Minerals exploited include gypsum which is mined in Tana River in the Coastal<br />

belt, Kajiado near Nairobi and in Turkana in North Western Kenya. Gypsum is mined and<br />

supplied to local cement plants and some is exported to Uganda<br />

Kenya boasts of a wide range of coloured and ornamental stones of gem quality, which are<br />

mined in the country. These mainly include, in order of importance, ruby, tsavorite, sapphire,<br />

various types of garnet, peridot, tourmaline, aquamarine and others.<br />

Lead was being produced from galena, which was being mined in small quantities in the<br />

coastal belt, where it was smelted together with scrap lead to manufacture lead batteries.<br />

Gold is known to occur in a number of places in gold bearing greenstone rocks of Nyanzian<br />

Craton in Western Kenya. Areas with alluvial gold are being harvested by local miners<br />

through conventional panning in the northern part of the country.<br />

Titanium and zirconium production<br />

Substantial deposits (3.2 billion tonnes) of mineral sands containing ilmenite, rutile and<br />

zircon along the Kenyan Coast have been established through exploration work by Tiomin<br />

Resources Inc. of Canada. These deposits occur in Kilifi, Kwale, Mambarui and Vipingo<br />

areas. Tiomin is focusing first on the Kwale deposit owing to its higher grades of the minerals.<br />

The mineralized sand deposits in Kwale amount to 200 million tonnes which is approximately<br />

6% of the total identified deposits in the Coast Province. Tiomin will mine about<br />

140 million tonnes that are economically recoverable out of the 200 million tonnes over a<br />

period of 14 years. The value of minerals to be extracted at Kwale over this period is<br />

approximately US$ 695 million. During the first 6 years output would be more than<br />

330,000 tonnes ilmenite, 75,000 tonnes rutile and 37,000 tonnes zircon per year.<br />

10


Tiomin estimates that it will spend US$ 150 million in construction of the project facilities<br />

and another US$ 415 million as operating costs during the project’s 14 years life span.<br />

During the first 5 years of production the Government will receive approximately US$ 2.5<br />

million as royalty per year and is expected to increase thereafter. The Government will also<br />

receive income tax, corporate tax and other taxes. In addition the project will contribute<br />

to GDP growth.<br />

During its construction phase the project would create about 1,000 direct jobs with additional<br />

employment in the operational phase. A further 1000 jobs would be created indirectly<br />

through sub contracting and provision of goods and services to the project.<br />

The project would expend about US$ 20 million in Coast Province alone every year. Out<br />

of this US$ 2.0 million will be for salaries and wages. In addition the company will improve<br />

infrastructure and construct social amenities in the area. At the resettlement site, Tiomin<br />

will construct two primary schools, two secondary schools, two dispensaries, one health<br />

centre, two social halls, water supplies at each settlement village and relocate and built<br />

churches and mosques that exist at the mine site.<br />

The Company is expected to start the construction phase of the Kwale Project this year<br />

after the compensation and resettlement issues have been completed. Production is to<br />

commence in 2007.<br />

Mineral commodities contributed about one per cent of the Gross Domestic product<br />

(GDP). However, there exists tremendous potential that awaits exploitation. Investors are<br />

expected to take up the opportunity presented to them in the form of favourable fiscal<br />

reform to invest in mineral exploration and mining.<br />

Headquarters in Nairobi. The information is currently being computerized and digitised<br />

for easy retrieval.<br />

Geophysical Data<br />

Since 1970’s several areas have been covered by airborne geophysical surveys in search of<br />

minerals. Information on the main airborne surveys can be obtained from the Mines and<br />

Geology Department.<br />

The available geophysical data will be of interest to the investors who wish to have test surveys<br />

prior to planning large scale exploration programmes. However, the existing geophysical<br />

data is not computerized.<br />

Geochemical Data<br />

Geochemical exploration has been conducted in several parts of the country in varying<br />

degrees. All areas mapped after 1970 had reconnaissance geochemical survey conducted<br />

along with the mapping. This involved collection of stream sediments, heavy minerals and<br />

grid soil samples. Geochemistry has been conducted in areas of revision mapping and<br />

ground geophysical programmes. A large part of the country has been covered by this type<br />

of geochemical data and is available at the Department’s library and archives.<br />

Topographical Maps<br />

Maps of scale 1:250,000 cover the whole country while scale 1:100,000 and scale 1:50,000<br />

are available for most parts of the country. Dates of publication do vary.<br />

Aerial Maps<br />

Most part of the country is covered by aerial photographs of varying scales and dates of<br />

coverage.<br />

Laboratory services and related Utilities<br />

∗ The Mines and Geological Department has facilities for chemical, mineralogical and<br />

petrographic analysis, fire assay and ore dressing at a nominal cost.<br />

∗ The nuclear Centre at the University of Nairobi offers analytical facilities at a cost.<br />

∗ The Mines and Geological Department offer drilling services at a cost. There are<br />

other companies in the country that offer drilling service on commercial basis.<br />

MINING OPPORTUNITIES<br />

There exist high mineral potential areas i.e. the gold bearing greenstone belt of Western<br />

Kenya and Mozambique Belt in Central and Southern Kenya. Several exploration companies<br />

have been granted exploration licenses to explore for gold and base metals in these<br />

areas. Some of the above high mineral potential areas have been staked by both local and<br />

foreign companies. Investors may wish to enter into joint ventures with companies already<br />

holding exploration concessions.<br />

Kenya has a well developed transport and communications system, which is progressively<br />

being improved and modernized to meet the needs of the expanding economy. A well-<br />

12


developed road and air network, seaports, posts and telecommunication facilities provide<br />

back-up to industrial development.<br />

Introduction<br />

About two-third of Mozambique, including the inland areas in the north are underlain by<br />

igneous and metamorphic rocks of Archean to Neoproterozoic age. Phanerozoic terrains<br />

are found south of the Zambezi valley and along the coastal belt in the northeast.<br />

Archean and Paleoproterozoic terrains are an extension of the Zimbabwe Craton and its<br />

supracrustal, but also include granitoids, gneisses and migmatites of the Barue Complex.<br />

Two main orogenies are recognised, the Iumide belt (1800-1350 Ma) in the northwest and<br />

the Ubiquitous Mozambique Belt (1100-850 Ma), with evidence of extensive migmatisation<br />

and granitisation as well as various granitoids and supracrustals; together these terrains<br />

constitute about 90% of the Precambrian rocks of<br />

Mozambique. The Neoproterozoic Cycle (800-410<br />

Ma) is marked by the the formation of the small platform<br />

basins, as well as the influence of the Pan-African<br />

(Katangan) orogeny in the northwest, and by the<br />

emplacement of monzonites, syenites, granites and<br />

pegmatites. Carboniferous to upper Jurassic rifting<br />

associated with sedimentation and widespread igneous<br />

activity led to numerous intercratonic Karroo basins,<br />

followed by Post-Karroo continental deposits and volcanics,<br />

as well as Meso-Cenozoic continental and<br />

marine deposits, and a thick Plioctocine and<br />

Quaternary cover.<br />

<strong>MINERAL</strong> RESOURCE <strong>AND</strong> GEOLOGICAL<br />

INFORMATION IN MOZAMBIQUE<br />

BY NATIONAL DIRECTORATE OF GEOLOGY OF MOZAMBIQUE<br />

The economic mineral potential is largely untapped.<br />

Gold has been produced from the Archean Manica<br />

Greenstone Belt and various alluvial occurrences; large<br />

BIF deposits are also known in this terrain. Numerous<br />

pegmatite fields host important deposits of tantalumniobium,<br />

rare earths and semi-precious stones. In<br />

addition, heavy-mineral sands, graphite, flourite,<br />

apatite, bauxite, dimension stone, various clays, sands,<br />

refractory minerals, limestone, coal and natural gas<br />

form the bulk of the mineral endowment of the country.<br />

After national independence, the government of Mozambique launched an increased geological<br />

study for mineral exploration and geological mapping in the country which resulted<br />

in identification of several new mineral deposits. However, in 1983 when the civil war<br />

intensified the geological mapping and mineral exploration fieldworks were forced to be<br />

14


educed to a large extent. In 1999 the government relaunched extensive geological studies<br />

over the large parts of the country, in order to increase the geological information availability<br />

and archiving it systematically for publishing and promotional purposes. During this<br />

period the National Directorate of Geology undertook the following activities:<br />

- Geological mapping of Niassa and Manica Greenstone Belts<br />

> From 1999 up to 2000: Ngoo, Cobue and Lupilichi in Niassa Province;<br />

> From 2002 up to 2003: sheets 1437 and 1438 in Niassa-Nampula Provinces; and<br />

about 25,000 Km 2, which covered the districts of Cuamba, Metarica, Muoco,<br />

Nipepe, Ribáuè, Iapala, Malema and Mutuali;<br />

- Geological prospection in selected areas<br />

> In 1999, the field work covering 280 km 2 was directed to exploring ornamental<br />

stones in Gorongosa area and two types of rocks with economic interest were identified:<br />

* Granito negro (olivínic gabbro and dolorito) in Mfumo Domba, Monte<br />

Ndemera, Monte Nhade areas;<br />

* Granito róseo (granular granite and granitoides) in Serra Carabina and Serra da<br />

Gorongosa areas.<br />

> In 2000, the field work in Espungabera area was carried out and 297 km 2 was covered<br />

with promising areas of granito negros:<br />

* Basalto de Chinica, Monte Cibeche, Corneana de Rio Caja, Chirarue, Monte<br />

Chicono, Basalto do Monte Mangala.<br />

* Xisto Ardósio, sources of thermal water in Vira-Vira and Régulo Wilson zone.<br />

> In 2002, Tete Province was explored covering 499 km 2 with:<br />

* Granitos (negro, castanho) with economic interest in Nhatipissa, Ratoneira,<br />

Nhambia, Txisita, Buzimuana, Moatize e<br />

Catema; along Tete-Songo in Cahora Bassa<br />

region.<br />

> In 2003 the fieldwork was undertaken in Cahora<br />

Bassa and Changara Districts and granites were<br />

identified in Maroeira, Nditi, Cahora Bassa,<br />

Kadzipande and Thaka areas.<br />

- Development of Geological Infrastructure Project<br />

Geological mapping project with the aim of<br />

improving the existing geological information and<br />

acquiring new information using different methodologies<br />

is underway at present. This project has the<br />

following geological mapping tasks (see Fig 2):<br />

> Comprehensive re-mapping of areas underlain<br />

by Precambrian rocks (Areas A, B, C, and D) at<br />

a scale of 1:250,000 and selected 1:50,000 map<br />

sheets.<br />

> Revision of the geology of the Phanerozoic<br />

rocks (Area C)<br />

> Introduction of contemporary, systematic lithostratigraphic<br />

classification<br />

> Production of modern geological map coverage<br />

and explanations in digital format<br />

Geological mapping of Area A<br />

Between 2003 and 2004 a consortium of three European companies namely the<br />

Norconsult, Norway Geological Survey and British Geological Survey, performed the geological<br />

mapping and covered 31 map sheets in Niassa and Cabo Delgado Province.<br />

Geological mapping of Area B<br />

The Geological Survey of Finland (GTK), ITC and Gondwana consortium undertook the<br />

geological mapping of 24 map sheets in Tete Province and parts of Manica, Sofala and<br />

Zambézia provinces.<br />

Geological mapping of Area C<br />

The mapping of the southern region of Mozambique was done by GTK, ITC and<br />

Gondwana from 2003 up to 2005 covering 29 map sheets.<br />

Geological mapping of Area D<br />

The South African Council for Geoscience (CGS) and the National Directorate of<br />

Geology of Mozambique (DNG) undertook the geological mapping of 12 map sheets in<br />

Nampula, Zambézia and Tete Provinces from 2001 to 2004.<br />

Aeromagnetic and Radiometric Survey<br />

The historical geophysical data set, from early 1970’s,<br />

covering the northern part of Mozambique was conducted<br />

by CGG of France. The survey included total<br />

magnetic field and total count radiometrics.<br />

The second set of airborne geophysical data covering<br />

the central zone, which included gamma-ray spectrometric<br />

measurements (TC, Th, U, K) was conducted by<br />

Hunting Geophysics between 1982 and 83. The data<br />

is available at the National Directorate of Geology in<br />

digital format.<br />

As part of the geological infrastructure development<br />

project, regional and detail aeromagnetic and radiometric<br />

surveys were conducted by FUGRO on selected<br />

areas. The survey details for the regional survey, flown<br />

in 2003/04, were as follows:<br />

• Line spacing and trend of 1,000 meters at 90o , with<br />

gradiometer;<br />

• Tie line spacing and trend of 10,000 meters at 180o ,<br />

with gradiometer;<br />

• Sensor clearance: magnetic and radiometric at 100<br />

meters;<br />

• Data recorded: magnetic total field horizontal gra-<br />

diometry and Gamma Ray Spectrometry; and<br />

• Data sampling: magnetic and radiometric at 8.5 meters (0.1 sec).<br />

16


Detailed airborne survey for total magnetic and gamma-ray spectrometric data was<br />

acquired in 2004/05 on 6 selected areas. Survey details were as follows<br />

• Line spacing and trend of 300 meters at 90 o , with gradiometer<br />

• Tie line spacing and trend of 3 000 meters at 000 o , with gradiometer<br />

• Sensor clearance: magnetic and radiometric at 80 meters<br />

• Data recorded: magnetic total field horizontal gradiometry and Gamma Ray<br />

Spectrometry<br />

• Data sampling: magnetic 7 meters (0.1 sec) and radiometric at 70 meters (0.1 sec)<br />

The digital gridded data set is available at DNG and consists of the following individual<br />

data grids in GEOSOFT format, gridded at 250m cell size:<br />

* Total field magnetic, reduced to the pole magnetic, calculated vertical gradient, calculated<br />

horizontal gradient, analytical signal, IGRF corrected magnetic;<br />

* Potassium %, equivalent uranium ppm, equivalent thorium ppm, natural air absorbed<br />

rate, uranium/thorium ratio, uranium/potassium ratio, thorium/potassium ratio, digital<br />

terrain model;<br />

* Line data (Magnetic): Line Number, GPS time, fiducial, date, flight, aircraft registration,<br />

GPS latitude/longitude in WGS84 , X / Y co-ordinates in UTM, magnetic raw,<br />

residual diurnal correction, magnetic levelled, radar altitude, barometric altitude, terrain<br />

elevation and<br />

* Line data (Radiometric): Line Number, GPS time, fiducial, date, flight, aircraft registration,<br />

interpolated latitude/longitude in WGS84, Interpolated X/Y co-ordinate in<br />

UTM, raw total count, raw potassium, raw uranium, raw thorium, processed potassium,<br />

processed uranium, processed thorium, radar altitude, barometric altitude, terrain<br />

elevation, temperature.<br />

Geochemical surveys<br />

The first significant geochemical exploration work was<br />

carried out by Borches. From 1970 to 1974 geochemical<br />

exploration was conducted on a broader scale,<br />

mostly by Portuguese and French teams, and by the end<br />

of 1974 about 19% of the country had been surveyed at<br />

the reconnaissance and regional levels mostly for base<br />

metals.<br />

Most of the major geochemical surveys carried out at<br />

this period were executed by private companies with<br />

technical assistance of geologists from the National<br />

Institute of Geology of Mozambique. About 270,000<br />

km 2 or 34% of the country was surveyed using various<br />

geochemical sampling methods.<br />

Most of the geochemical data was available only as<br />

hard copy maps and data tables. Original heterogeneous<br />

data (methodology, elements, missing results)<br />

had to be gathered in order to establish the use of<br />

existing information. Maps had to be scanned, georeferenced<br />

and digitized which involved considerable<br />

amount of manual work. In these surveys only base<br />

Fig 4: Status of Geochemical survey of Mozambique (2004)<br />

metals have been analysed by AAS. Gold was not<br />

analysed. New surveys with multi-element analysis generally cover only small areas.<br />

17


During the GEODESA project of <strong>SEAMIC</strong> in 1998 and 1999, different digital data sets<br />

of Manica, Tete and Zambezia Provinces were digitized, which included the following:<br />

• The sample locations including the assay (Cu, Co, Ni, Zn) of Mavita-Gogoi area in<br />

Manica Province;<br />

• Generation of Mineral Occurrence data set from the same map (commodity, type of<br />

mineralization, location and commodity number);<br />

• Digitalization of sample location points from Regional reconnaissance and follow up<br />

geochemical maps and join assay data (Cu, Co, Ni, Zn, Pb) scanned to MS Excel;<br />

• The UNDP Geochemical maps (Cu, Co, Ni, Pb, Cr, Mo, Zn) of Tete province namely<br />

Monte Caperimbeua, Rio Máuè, Cadzomba, Metengobalame, Macungua, Cacomue,<br />

Dezenza, Chitipi, Capitaciria, Namadende, Domue and Furancungo have been digitised<br />

and the data are available;<br />

• The data set from Zambezia Province done by Aquater (20 elements) was converted to<br />

MS Excel format which can be imported into any GIS package; and<br />

• Under Greenstone Belt project (Lupiliche-Metangula, Niassa province) - Geological,<br />

geochemical, stream sediment samples, rock samples and ternary maps at a scale<br />

1:50,000 have been produced and digitized.<br />

As part of Mineral Resource Management Capacity Building Project, Geochemical and<br />

Industrial Mineral Surveys (GIM) were started in March 2005 by a consortium of GTK<br />

and Gondwana Ltd. The survey is expected to be completed by the end of 2007.<br />

The project was divided into three phases:<br />

- Phase I: Compilation and synthesis of existing data (info of earlier geochemical surveys,<br />

available samples (including reanalysis), design of GDB, training, GIS)<br />

a) Scanning of the maps (map mosaics)<br />

b) Georeferencing<br />

c) On-the-screen digitizing (data tables):<br />

1) sample points<br />

2) calculating the coordinates (UTM/ WGS 84/Zone 36S - metric system)<br />

3) adding the analytical data into data tables<br />

d) the Survey Information Table (SIT); METADATA<br />

e) the Analysis Data Tables (ADT) containing the actual analytical and coordinate<br />

data (UTM/WGS 84 -Zone 36S).<br />

- Phase II: Execution of new surveys (two stages: fieldwork and training)<br />

1) regional soil sampling survey, and<br />

2) detailed soil-sampling<br />

- Phase III: Final Products (GDB with existing survey data)<br />

at the level of government institutions in Africa was held in Maputo, Mozambique<br />

from 11 to 14 April 2006. The workshop was attended by 85 participants including officials<br />

from 16 African countries.<br />

formulation.<br />

The main objectives of the workshop was to<br />

create a critical mass of informed policy<br />

makers in the sectoral ministries responsible<br />

for mining as well as in the ministries of<br />

planning, finance and economic development,<br />

raise their awareness on the potential<br />

of minerals clusters in supporting long-term<br />

economic development and growth, provide<br />

them with tools for mineral policy design<br />

and implementation, and enhance their<br />

knowledge and capacity in mineral-related<br />

subjects, which are important to create a conducive<br />

environment for mineral resources<br />

development. With focus on minerals clustering,<br />

the workshop covered economic and<br />

legal issues, as well as the process of policy<br />

The workshop was jointly organized by ECA, UNCTAD, the Southern and Eastern<br />

African Mineral Centre (<strong>SEAMIC</strong>), the Centre for Energy, Petroleum and Mineral Law<br />

and Policy (CEPMLP) of the University of Dundee, MINTEK of South Africa, DFID of<br />

UK, and the government of Mozambique.<br />

Management of Geological Surveys<br />

The Centre organised a two-days workshop<br />

on “Management of Geological Surveys:<br />

Mandate and Financing” from 8the to 9th<br />

May 2006. The workshop was facilitated by<br />

Dr. David Ovadia and Dr. David Morgan<br />

of the British Geological Survey (BGS) and<br />

was attended by Directors of the Geological<br />

Surveys of the member States and other<br />

countries in the region. The aim of the<br />

workshop was to create a forum for interaction<br />

of geological infrastructure development<br />

stakeholders to discuss the mandates<br />

of Geological Survey Organisations and<br />

what public should expect from their activities.<br />

The workshop discussed, among<br />

other things the following topics:<br />

∗ Current status of the geological surveys in Africa;<br />

∗ How can their relevance be improved and have impact on decision makers;<br />

∗ Lessons to be learnt from surveys in other continents; and<br />

∗ Capacity building efforts in the national geological surveys.<br />

Shareholders Agreement Conference<br />

The long awaited, ratification of the Shareholders Agreement concept has been effected by<br />

Mozambique, Tanzania and Angola. Upon the decision of the 26th Governing Council<br />

meeting, a conference was held on 27th November 2006 that constituted the representatives<br />

from member States of <strong>SEAMIC</strong>, the private sector and academic institutions to discuss<br />

on the shareholding concept and the restructuring of <strong>SEAMIC</strong> to accommodate the<br />

changes. The conference also discussed the implementation of the shareholding concept<br />

once it is approved by the Governing Council with an incentive to attract the participation<br />

of the private sector and other stakeholders to ensure financial sustainability of <strong>SEAMIC</strong>.<br />

The conference was attended by participants from geological survey organisations of<br />

<strong>SEAMIC</strong> member States and European countries, the private sector and other government<br />

institutions.<br />
