Tintina Gold Belt

Establishes environmental geochemistry and ore genesis of the Red Mountain exposed, unmined volcanogenic massive sulfide deposit in the Bonnifield district. Provides pre-mining baseline geochemistry should the deposit ever be developed, and the metallogeny and tectonic settings of the deposits.

Abstract


Environmental geochemistry and ore genesis studies (headed by Bob Eppinger and Cynthia Dusel-Bacon, respectively) were conducted for a belt of unmined volcanogenic massive sulfide deposits in the Bonnifield district, most notably the peralkaline rhyolite-hosted Red Mountain deposit (also referred to as the Dry Creek deposit). The environmental study establishes the pre-mining baseline geochemistry from the unmined Red Mountain massive sulfide deposit, should the deposit ever be developed (the most recent exploratory drilling ended in 1999), and serves as an analog for similar deposits where mining is or was underway and where pre-mining baseline geochemistry is lacking. Ore genesis studies determined the metallogeny of the ca. 360 Ma deposits, including their tectonic and geologic settings and global analogs. These studies were combined in a single task within the Tintina Gold belt project headed by Larry Gough.
