Powderhorn Exploration Project
Powderhorn Exploration Project is a rare earth occurrence in Colorado, recorded in the USGS USMIN rare earth element occurrence database (ver. 4.0, June 2019).
Location: Colorado, United States
Commodities: rare earth elements
Deposit model: Fe-Ti-REE pyroxenite · carbonatite · carbonatite deposits · unclassified
Geology
“The Powderhorn Project is located on BLM lands in southwestern Colorado and is accessed from Gunnison, Colorado by traveling on paved road west on US50 for 9.4 miles, then traveling south on CO149 for 16.9 miles, then left onto CO Road 27. Accesses to the prospect properties are along BLM and county developed and undeveloped four wheel drive roads. All other access is by foot or helicopter. Access to the Powderhorn Project and the location of prospect contiguous claim blocks are shown in the map in Figure 5 below.” (U.S. Rare Earths Inc. (2015b)) “To date, we have focused our initial exploration activities on the Powderhorn. The Powderhorn Project is divided into two prospects-the Satellite prospect and the Rudolph Hill prospect. We completed Phase I diamond core drilling on the Satellite and Rudolph Hill prospects in 2011. Our exploration also included several grab sampling traverses. Results indicate low to moderate rare earth element mineralization that requires further work to identify the exact location and dimensions (length, width and depth) of the mineralization. Evaluation of the Powderhorn Project is still in an early phase of investigation as mapping and detailed work has yet to be completed.” (U.S. Rare Earths Inc.

Exploration and site history
- Exploration — Phase I diamond core drilling on Satellite and Rudolph Hill; Grab sampling traverses, 2011 (U.S. Rare Earths Inc. (2015b))
- Exploration — Our predecessor also completed grab sampling between and 2007 and 2010 indicating several localities of anomalous rare earth mineralization within the Powderhorn Project claims, 2007–2010 (U.S. Rare Earths Inc. (2015b))
