Comments on the geologic information

  • Geologic Description = The country rocks in the area of this prospect are the Paleocene Cantwell Formation, which consists of andesite, basalt, rhyolite and dacite flows, pyroclastic rocks, a few interbeds of sandstone and a few small bodies of related subvolcanic intrusive rocks. Little information about this deposit has been made public. Apparently, it consists of auriferous quartz veins in the Paleocene volcanic rocks.
