This active gold mine is quite large and can be seen for a few miles. DAY THREE: I think that is Los Alamos Gold Mine https://www.alamosgold.com/mines-and-pr ... l-Chanate/ Historical workings suggest the area has been mined for gold since the early 19th century.
Geology
El Chanate’s main structural feature is the Chanate fault zone, a 7km-long northwest-striking, variably southwest-dipping structure. The area is underlain by deformed sedimentary rocks of the Late Jurassic-Early Cretaceous Bisbee Group and the Late Cretaceous Chanate Group, which locally are overlain by andesites of the Cretaceous El Charro volcanic complex.
