Verification

Multiple Sources Confirmed

Independent historical source evidence corroborates underground workings.

Why confirmed?

Confirmed by independent Arizona Geological Survey / ADMMR historical documentation describing underground workings, in addition to USGS MRDS catalog eligibility. Not a member field verification.

Why it's listed

Source records document both underground and surface mining.
