Near the summit of Fremont Pass, in Lake Co., approximately 15 miles north of Leadville. Owned by AMAX Corp. A molybdenum mine comprised of a large open pit and underground workings. When working up to 50,000 tons of ore processed daily.
Produced stopped in 1985 due to low Mo prices, but will recommence during 2012.
32 valid minerals.
This information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This data will improve over time as more accurate maps and data sets are added.
|Pennsylvanian298.9 - 323.2 Ma||Minturn Fm in west-central and south-central and other units|
Arkosic sandstone, conglomerate, shale, and limestone. Includes Madera Fm and Sharpsdale Fm of Chronic (1958) in Sangre de Cristo Range and Gothic Fm of Langenheim (1952) in Elk Mountains. Other units of Middle Pennsylvanian age.
|Paleoproterozoic1600 - 2500 Ma||Paleoproterozoic metamorphic and undivided crystalline: sedimentary and volcanic gneiss|
Metamorphic and undivided crystalline: sedimentary and volcanic gneiss
|Paleoproterozoic1600 - 2500 Ma||Paleoproterozoic intrusive and metamorphic terranes|
Intrusive and metamorphic terranes
Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
