Mining that has taken place is mostly deep-level underground mining, exploiting the narrow, generally shallow dipping tabular reefs. The Basal Reef is the most common reef horizon and is mined at all shafts except Target and Joel.

Silver: A native element, mineral, alloy, and byproduct

Most gold found in placer deposits is alloyed with small amounts of silver. If the ratio between gold and silver reaches at least 20% silver, the material is called "electrum." Electrum is the name for an alloy of gold and silver. A significant amount of today''s silver production is a refining byproduct of gold mining.
