The Mine is located in the South-West of Saudi Arabia at an elevation of 1620m, and approximately 640km South-East to Jeddah. It lays about 414km away from Jazan Port on the Red Sea, connected to Najran by a newly paved road, and 835km away from Jeddah. The nearest communities of significant size are Khamis Mushayt which is 190km away, Abha to the West is 220km away and Najran to the South-East is approximately 100km away from the mine site.
The mineralized zones, Sa’adah, Al Houra and Moyeath have been outlined by diamond drilling. The Sa’adah and Al Houra zones occur in a volcanic sequence that consists of two mafic-felsic sequences with interbedded exhalative cherts and meta-sedimentary rocks. The Moyeath zone was discovered after the completion of underground development in 1981. It is located along an angular unconformity with underlying felsic volcanic and shales. The principal sulphide minerals in all of the zones are pyrite, sphalerite and chalcopyrite. The precious metals occur chiefly in tetra-hydrate and as tellurides and electrum.
The total Measured and Indicated Resource at Al Masane Deposit is 9.4mt grading at 4.23% Zn; 1.21% Cu, 0.97g Au/t and 31 g Ag/t. The total Inferred Resource is 0.6mt, grading at 7.42% Zn, 1.00% Cu, 1.18 g Au/t and 13g Ag/t.
