A group of former Pb-Zn-Ag-W-Cu-Au mines.
NOTE: This group of mines was leased by the firm Mexicanus Colorado Inc. during the early 1970's. The name is mis-spelled in the MRDS database and appears as "Mexicanus Colovgdo Inc A" under MRDS file #10188132, referencing the USGS Minerals Yearbook 1972: 26, 30.
The Company βProject Darwin LLCβ acquired the Darwin Mines and 58 patented mining claims in 1996. They have prepared a good description of these mines and their history and put it on a webpage (see under Links).
Mineralization is a polymetallic replacement deposit (Deposit Model: 72: Polymetallic replacement) hosted in rocks of the Portachuelo Formation (limestone, granodiorite).
Local structures include a thrust fault, igneous intrusions, faults, and folds.
