Quartz Mountain is a later stage exploration project located in south-central Oregon. Over the years, approximately 80,000 metres of drilling has been conducted, with the majority of work focused on the Crone Hill and Quartz Butte deposits, which host the current Inferred Mineral Resource. The project covers a land package with significant exploration potential.
The Quartz Mountain gold district is located in a Mid-Tertiary volcanic highland within the northern transitional zone of the Great Basin. This highland area is characterized by a bimodal volcanic suite consisting of basalt flows and tuff with rhyolitic dome complexes. Hydrothermal alteration in the district is characterized by acid leaching of the host rocks and subsequent precipitation of quartz in the gold zones. Mineralization at Quartz Mountain represents a low-sulphidation epithermal system based on the characteristic mineralogical assemblage of adularia, cinnabar and stibnite. Alamos envisions Quartz Mountain as an open pit and heap leach operation.
