Gordma, and hemetal prospects of volcanogenicvolcano
sedimentary type (AbetseIo, Kata);
- a northern domain (Tigray) extending northwards towards
Erika, composed of several metamorphic metavolcanosedimentary
belts and sub-belts, bounded by m&cuItramafc
rocks, hosting gold and base-metal occurrences
(e-g., Adi Zeresenay, Au).
Significant metallic mineral sites l o w outside of these domains
are rare, and include the Melka Arba iron deposit (basic intrusionrelated),
the Chercher copper deposit (Red Bed type in Mesozoic
sandstones) and the Edcafah manganese deposit (Plio-Pleistocene
sediments of the D 4 depression).
Industrial minerals and rock resources occur in more
diversified geological environments, including the Proterozoic
basement rocks, the Late Paleozoic to Mesozoic sediments and
recent (~zoic) voIcanics and assooiated sediments. The
occurrences of energy resources (oil, mtmd gas, coal, geothermal
resources) are restricted to Phaneromic basin sediments and
Cenozoic volcanism and rifting areas.
The discovery of the primary gold deposit at Legadembi
(Southern Ethiopia), which has mched a production stage, can be
cited as the best example of the significance of systematic
exploration conducted in the recent years. Furthermore, the recent
discovery of eluvialdeluvial gold in western Tigray (Adi Daro,
Asgede and Daro Techi) and fie Werri gold and base metals by
Wemi Gold Project (NMIC); discoveries of gold and base-metals at
1dities Gale Repwr, Awm, Epbo (Bden, Benishangd
Gumuz) and Boseti locality (Adola); gold deposit at Okote (Dawa
Digati area; currmtly under intensive exploration by bore holes) by
Midroc Lega Dembi mineral exploration project; and base-metals
(copper) and gold occurrences of WacRile and Gewle in Arero
Womda, Borena zone (Southem Ethiopia) by the Ethiopian
