Gavilan Prospect

Silver-Lead-Zinc Skarn of CRD Property
780 hectares - 100 % title interest

Location: The Gavilan property is located in the San Joaquin mining district on the eastern border of the state of Queretaro, Mexico, a 2.5 hours drive from the capital city of Queretaro. A further 4km on good gravel roads accesses the property.

History: The San Joaquin District has been mined intermittently for over 300 years starting with the early Spanish settlers extracting high grade silver from veins and then later Hg was mined from other veins. More recently the nearby La Negra Mine of Peñoles (about 20 km from San Gavilan) produced about 20 Moz of Ag between 1972 and 1986. None of the mines have been open in the last 20 years. Much of the San Joaquin area was Nationalized by the Mexican government in the 1980's and did not come open for staking until 1993. The area surrounding and including the Gavilan claim has been held by private individuals since then, but has not seen an exploration work in that time.

Geology: The area of the Gavilan Project is located on the western margin of the Sierra Madre Oriental, a NNW trending mainly carbonate package of rocks. The Las Trancas Fm is the main group of carbonate rocks exposed on the property and these have been intruded by a younger granite to granodiorite stock exposed mainly just to the east of the ground held by Soltoro. Numerous old mineralized prospects occur within this intrusive stock and along the western contact, as well as further out into the nearby carbonates. The prospects visited in 2006 by Soltoro geologists showed a variety of mineralization styles from veins to contact skarn / replacement. Rock samples returned strongly anomalous values in Ag, Pb, Cu, As, Sb as well as Au. It is thought that with such strongly anomalous values within the intrusive stock and along its border area, the conditions are very good for developing a contact skarn or CRD deposit on the ground controlled by Soltoro (the contact of the intrusive is thought to follow the eastern boundary of the Soltoro claim).

Recent programs: No work has been completed on this property in the last 12 years, since the area came out from National Mineral Reserve. The property needs further geologic mapping and sampling to locate all the mineralized prospects and structures to then identify areas for drill testing. Soltoro has conducted a preliminary assesment with no work planned in the immediate future.
