Exploration work and mining activities planned for
the period 2011-2015
According to a recent Resources Statement (28 May 2011)
based on JORC Code and Guidelines (2004) and to JORC
Exposure Draft, Inferred Mineral Resources, Proposed
Changes to the JORC Code and Guidelines (4 August 2006),
the Company has a near-surface (30 m) Inferred Mineral
Resource of 148 million tons containing 1.63 million tons of
copper metal and 110 tons of gold. The (median) grade
values are 1.1% for copper and 0.75 g/t for gold. An
adjusted version, regarding the role of unproductive
overburden and waste rock in this near-surface deposit,
accounts for 104 million tons containing 1.14 million tons
of copper and 77 tons of gold.
Continuing exploration will quickly add further resources
beneath the 30 deep �oor of the current resource block.
The company has an Indicated Mineral Resource of 1.14
million tons containing 11.400 tons of copper (median
grade of 1.0 %) and 0.46 tons of gold (median content of 0.4
g/t). This resource could be converted into the corresponding
mineable category of a Probable Mineral Reserve of
1.05 million tons containing about 9,000 tons of copper
(median of 0.85%) and 0.36 tons of gold (median of 0.34
g/t) which is going to be mined. This mining site in the
north of RABIA’s geological corridor is called ‘Mina
Hornito’, an old local name for the site. With continuing
exploration towards depth, further resources and
mineable reserves will be added.
At the ‘Mina Hornito’ site, regarded by the Company as the
starting point for its mine cycle, Chilean contractors are
going to mine up to 500 tpd run-of-mine (r.o.m.) ore within
a �at open pit design. Part of the production is sold to a
Chilean leaching plant run by ENAMI, the rest is stockpiled
for transport to the deep water port of Huasco.
The production rate shall be increased stepwise (500 – 800
– 1,100) up to 1,500 tons r.o.m. ore per day. This
corresponds to a life time of the Probable Mineral Reserve
block of four years, still as open pit mining site.
Upon exploration results available from deeper zones and
with ongoing development of the mine, a �nal long-term
daily production rate of several thousand tons of r.o.m. ore
should be possible, especially when approaching the bulk
of secondary copper sulphides in the assumed supergene
enrichment blanket, and later the potential mass deposit at
greater depths containing the primary copper sulphides,
very similar to the common porphyry copper mass deposits.
