The terrain of parts of the northwestern Mexican landscape in the state of Sinaloa is not particularly inviting, unless you happen to be into wandering barren soil, if you have a taste for the lonely, if you are an airy bird of prey, or if you’re a geologist. For miles you can look and see sparse vegetation, blue skies and rocks, which stretch to the edge of the Sierra Madre Occidental Range. The dirt you walk on the hard ground covers the sedimentary rocks from the Cretaceous and Tertiary periods which were cut by volcanic intrusions. Near one such large intrusion, the granite Sinaloa Batholith, is the Magistral Project and the El Gallo Mine. Geologists—modern prospectors—who criss-crossed the vast open acreage near an old, sleepy gold mine, found something they weren’t looking for: silver. The elixir of finding the precious metal goes a long way toward explaining the quest for gold and silver, and the appeal of the exploration and discovery that the emerging mining companies called junior miners do, is obvious.
