Prospero Silver Corp. is pleased to announce that its JV partner Minera Hochschild Mexico, S.A. de C.V. has commenced a 3,000 meter Reverse Circulation drill program in the northern Cebollas target area at the Baborigame project in Chihuahua. This initial program on the northern part of the 8,458 Hectare claims is aimed at multiple targets defined during the past 6 months. Sampling over the felsic igneous body 2.5 km in length shows both rock-chip and soil sample anomalies, which indicate potential to host both near surface, bulk tonnage as well as high grade vein mineralization.

Mammoth Resources Corp. is pleased to report that gold observed from two core samples of un-oxidized hydrothermal breccia and an altered felsic volcanic selected for preliminary metallurgical test work occurred in as free gold associated with pyrite along pyrite grain fractures and on grain surfaces and that the rock in these samples was not oxidized. It is the opinion of Dr. Perez, who studied these samples that the gold is most likely leachable with cyanide and does not exhibit any major metallurgical complexities.

The Company has recently received results of an exploration program on the El Indio and Pelonachi properties which included mapping and channel sampling during the months of November to January. Also included was improvements to access roads in certain areas of the Pelonachi property. A total of 222 geochemical samples were taken on the El Indio property and 488 samples were taken on the Pelonachi property. The El Indio and Pelonachi claims are part of Alliance’s 4,872 hectare land package located totaling nearly 50 square kilometres primarily in the Uruachic district of northwestern Mexico. The land package puts Alliance in the heart of a prolific gold exploration area and includes the closest privately held claims, within four kilometres, to Fresnillo PLC’s important Orisyvo discovery (www.fresnilloplc.com). Fresnillo is the world’s largest primary silver producer and the second-largest gold producer in Mexico. However, the Orisyvo discovery may change that.

Riverside’s partner, Sierra Madre Developments Inc., is starting a minimum 1,500-meter drill program and is planning to test various parts of the high-grade Jesus Maria silver-gold vein system. The proposed diamond drill program will initially test beneath and adjacent to surface-sampled trench areas and along the structural trend of the vein system, and targets shallow intercepts along strike from high-grade Ag-Pb-Zn historic mine workings. This drilling is on less than 1 square kilometer of the greater than 300 km2 land package, which has more than 10 additional target areas controlled by Riverside in the historic Penoles District in northern Durango state, Mexico.
