Isbell Mine
We picked it because its USGS record mentions 1 of the minerals on our cards and 1 of our card minerals overall. That ties with 7 other site(s), so we broke the tie by mine status (past producers first), then USGS record quality, then name. USGS lists it as past producer for Copper. Minerals mentioned: Copper. Approx. location 33.651, -98.678. USGS record.
Ask first: a USGS record doesn’t mean you can visit. Find out who owns the land and get permission before collecting.
Field cards: what kind of sites?
The mineral was noted here, without development.
Produced ore or material at some point in the past.

How we built this page: we counted named sites in the USGS Mineral Resources Data System (MRDS) for this area, left out sand, gravel, crushed stone, clay pits and unnamed sites, grouped them by Census county, and linked every site to its USGS record. We did not visit these sites, and MRDS does not tell you who owns the land or whether collecting is allowed.
