RE:What does "NICO" stand for?
when the previous claims, BICO (Bismuth Cobalt) lapsed, a brilliant and distinguished prospector retake them as the NICO claims. You are correct, after Nickel Cobalt. The Great Bear silver deposits had a nickel cobalt association, so it was reasonable to assume that these obvious copper plus cobalt stained rocks might have nickel in with them somewhere. Alas, wrong type and age of deposit.
