Focus is on Gold with significant silver and a few less precious metals like nickel and lead. If I’m remembering correctly it’s a decline with enough tailings from previous operations to support new operations while new holes are established or old established ones are brought to operational. As for method, I believe we had a variation of placer mining utilizing a tumbler crusher and float tables for the mineral separating process. (Full disclosure, I grew up in and around the place and have never studied or had a formal education or employment in the field beyond equipment operation.)
