The Copperman deposit was discovered in 1927-28 after surface trenching yielded a maximum of 2.73% copper and 4.24% zinc across 10 feet. Initial drilling in 1928 identified one section of mineralization 400 feet long by 8 feet wide grading 2.58% copper and 3.91% zinc. The highest reported drill intercept was completed in 1966 which graded 8.09% copper and 7.29% zinc across a width of 23 feet.  

Multiple reported zones were identified with high-grade intercepts.  In 1967 it was reported that the “A” Zone was estimated to contain 170,000 tons grading 3.1% copper and 4.7% zinc. The “B” Zone was estimated to contain 74,200 tons grading 1.5% copper and 3.9% zinc.  The resource was defined above 1,000 feet vertical. Later drilling identified depth extensions to the mineralization below 1,000 feet but was never included into a new resource estimate. The deposit remains open along strike and to depth.
