Mining at Lida started in the 1860s as an outgrowth of the Aurora gold rush boom. Mexican and Native American prospectors worked small claims in the Lida region and in nearby Tule Canyon prior to 1867, when American prospectors organized a district. Mining for copper, gold and silver continued until the late 1800's but closed soon thereafter due to low grades and falling prices.
Small scale, historical mining activity focused on the No 1 shaft, which targeted structurally controlled primary copper mineralization comprising chalcopyrite, bornite and chalcocite. A structural zone adjacent to the No 1 shaft was reported to contain copper mineralization across a width of up to 30m.
The most recent exploration documented at Lida was by Conoco Inc in the 1960s and 1970s. Conoco identified a large IP anomaly, covering 2km by 500m, underneath the surface copper mineralised area. A single shallow borehole was drilled but failed to test the target or penetrate the Campito Formation to more prospective carbonate host rocks.
