The geology of Montana includes thick sequences of Paleozoic, Mesozoic and Cenozoic sedimentary rocks overlying ancient Archean and Proterozoic crystalline basement rock. Eastern Montana has considerable oil and gas resources, while the uplifted Rocky Mountains in the west, which resulted from the Laramide orogeny and other tectonic events have locations with metal ore. The Colorado Mineral Belt is not the only area of the Rocky Mountains to have hosted large ore mines. Park City, Utah was a site of a major silver rush in the s thanks to the finding of silver, gold, and lead; the town flourished for nearly one hundred years before silver prices dropped in the late s.
Other deposits include hematite-breccia complex deposits, magmatic-hydrothermal uranium in iron-oxide Cu-Au deposits and quartz-pebble conglomerate deposits (World Nuclear, ). Thorium is mined in conjunction with uranium, so much that estimates of reserves for these elements are made based off of uranium content.

McKnight. Geology and ore deposits of the Rico District, Colorado The Rico district is in the Dolores River valley at the east end of Dolores County in southwestern Colorado. Mining has been actively carried on in the district since In the early days, silver was the chief product and was mined largely from Newman Hill southeast of the town of Rico.
Rico, the Spanish word for “rich”, is the perfect name for this town blessed with natural resources. Ore deposits which stimulated mining development consisted of large gold strikes and The ore deposits of the Rico Mountains veins as well as some copper and lead-zinc discoveries (NMGS, ).

Middle Tertiary ore deposits of significant size and number replace the Eocene Telluride Conglomerate adjacent to northwest-trending base-metal veins on the north-west side of the Silverton caldera in the San Juan Mountains, rite, galena, chalcopyrite, and pyrite are the major sulfide minerals, and the ores contain some cadmium, bismuth, silver, and gold.
