Santa Rosa was operated as an underground copper mine by the Compania Minera Tarica S.A. in the 1960's. Quartz-pyrite-chalcopyrite-galena-sphalerite-molybdenite veinlets and mantos were mined on several levels. In 1967 the Guggenheim Exploration Company reported significant intersections of copper mineralization in five diamond drill holes. Rio Tinto continued exploration on the property in 1998 as part of a joint-venture exploration program with MacMillan Gold Corporation. Rio Tinto completed a preliminary series of drill holes along across a widely spaced grid in search of a potential bulk tonnage mineralized system. The results included several encouraging gold intervals that appeared to be related to feeder vein structures. Rio Tinto did not do any follow up work.
