Ouray District (Uncompahgre District), Ouray Co., Colorado, USA

The Uncompahgre mining district, part of the Ouray mining district, includes an area of about 15 mi2 on the northwestern flank of the San Juan Mountains in southwestern Colorado from which ores of gold, silver, copper, lead, and zinc have had a gross value of $14 to 15 million.

Ore deposits range from low-grade, contact-metamorphic through pyritic base-metal bodies containing silver and gold tellurides and native gold to silver-bearing lead-zinc deposits.

Contact-metamorphic deposits and most of the pyritic gold-bearing deposits were found in the central parts of the district. The silver-lead-zinc deposits were found chiefly in the northern and southern sectors of the district.
