sp&ial molybdenum-containing alloys, such as the Hastelloys, me<br />

notably heat-resistant and corrosion-resistant. Molybdenum is used<br />

in oil pipelines, aircraft and missile parts, and in filaments.<br />

Molybdenum finds use as a catalyst in the petroleum industiy,<br />

especially in catalysts for removing organic sulfurs from petroleum<br />

products. Ma-99 is used in the nuclear isotope industry.<br />

a Molybdenum ranges are pigme'nts ranging from red-yellow to a<br />

in paints, inks, plastics, and rubber<br />

Coppr, zinc, lead, molybdenum murmnees in Ethiopia<br />

Copper most promising occurrences seem to be related to<br />

volcanogenic massive sulphide (VMS type) mineralization<br />

occurring in the meta-volcano-sedimentary belts of Western<br />

Ethiopia (Abetselo, KatPr). Other occurrences are related to basicultrabasic<br />

magmatic rocks and copper is also a common pathfinder<br />

of gold in many shear-zone related "mesothermd" goId deposits<br />

(Table 2). The well-hown Cu-Mu-(Co) Chercher deposit in<br />

Eastern Ethiopia, hosted in Mesozoic sandstones discordant over<br />

the Precambrian basement belongs to the Red Bed type. Recently,<br />

the Ethiopian <strong>Mineral</strong> Development Sh. Co. have discovered<br />

copper occurrencm at localities Wachile and G d e in Arero<br />

Wore&, Borena zone (Southem Etbiopia). The copper minerds<br />

are malachite associated with meta-granite and &randorite. The<br />

localities are currently under intensive gmIogical and geophysical<br />

mmm<br />

Zinc, Lead, as well as other commodities (e.g. Ag, As, Sb, Bi) are<br />

associated with Cu and Au in polpetallic massive and<br />

disseminated sulphides of volcanogenic and volcano-sedimentary<br />

deposits (Kata, Abetselo, Azale-Akendeyu), as well as pathfinders<br />

y primary "lode" orogenic deposits. Other Pb or Pbs<br />
