The Tongyu copper Deposit is a small-sized copper deposit in volcanic rocks, which was explored by Geological Team No.8 of Shaanxi Province during 1972 and 1979, obtaining a proved copper ore reserves 10 478 800 tons including metal reserves 65 064.64 tons with an average grade 0.62%. There are 73 orebodies delineated in this area, 9 of which are dominant and contain 77% of the total ore reserves, including ore reserves 8 030 000 tons (metal reserves 49 778 tons) with an average grade 0.62%.The largest orebody numbered No.7 is a blind orebody, containing ore reserves 1.850 000 tons (metal reserves 13 826 tons) with an average grade 0.75%.The distribution of ore bodies are concentrated and present mostly in shapes of flat and pinch reproduction. The boundary separating orebodies and wallrocks is not clear and the ore zones vary a lot in thickness.
