The 17,000 hectare Solidaridad mining leases are held by U.S. Precious Metals of Mexico, a wholly owned subsidiary of U.S. Precious Metals, Inc. The Solidaridad properties include eight (8) concessions and have been granted to the subsidiary for 50 years. Titles to the concessions are maintained subject to an annual tax required by the Mexican government and paid twice a year.

USPR de Mexico acquired the property leases in 2003 after the initial exploration efforts by MIM, Esperanza Del Oro and Hot Springs Exploration in 1997-98. The previous exploration campaigns completed 21 drill holes totaling 3166 meters of R.C. drilling. An additional concession surrounding the Solidaridad concessions was obtained in 2006 by USPR of Mexico.

In 2008, USPR of Mexico began a 4000 meter drilling campaign to confirm, further explore and investigate the mineral resource potential. All drill cores were logged, cut and sampled. The core samples were shipped to a lab in the United States for assay. All data to include drill logs and assays have been digitized and plotted on maps. The mineral resource estimation provided by USPR of Mexico is based solely on the results of USPR drilling results.

Based on the results from the previous drilling campaign completed by USPR of Mexico, field mapping and sampling and petrographic results from polished section studies, a 10,000 meter drilling campaign is planned for 2010.
