Location

El Reventon is located in the municipality of Otaez, Durango and is approximately 170 kilometres northwest of the capital city of Durango.  Road access is good.

Overview

El Reventon was identified as an acquisition target by exploration staff early in 2006 as part of the Company�s generative exploration program. Initial sampling reported very encouraging silver-lead-zinc mineralization from the Reventon Breccia occurrence. Further reconnaissance and sampling programs in the area revealed the presence of a number of high grade silver-lead-zinc vein systems as well as potential for other bulk tonnage deposits. The company has compiled a land position of over 3500 hectares through staking and the option to acquire a 60 hectare concession. The company can acquire a 100% interest in the optioned concession by paying US$150,000 over a four year period.

Work Performed

The Company�s exploration programs to date have focused primarily on the Reventon Breccia pipe, which has an irregular surface expression of approximately 70 x 70 metres. A total of 51 channel samples taken from within the breccia have an overall average of 104 g/t silver. Two lines of continuous 2 metre samples within the breccia reported 48 metres @ 101.6 g/t silver, and 69 metres @ 118.7 g/t silver with early sampling averaging 166.5 g/t silver over 52 metres. Lead and zinc are strong within the central portions of the breccia, with >1% values common.

Company geologists believe that the Reventon Breccia could be significantly larger than exposed, due to extensive cover by post-mineral volcanics and Quaternary deposits; and the fact that the surrounding volcanics are intensly hydrothermally altered. Geophysical laboratory tests performed by a consulting firm on seven representative samples from the breccia indicated that the occurrence might respond well to a ground geophysical program.

An additional bulk tonnage target may have been located at the Los Alisos zone, which has a geochemical signature very similar to the El Reventon Breccia located approximately 500 metres to the north. Reconnaissance chip sampling at Los Alisos over an approximate 15 x 20 metre outcrop surrounded by colluvium reported values of 88 g/t silver over 15 metres. Most of the surface between Los Alisos and Reventon Breccias is covered by post-mineral volcanics, indicating good exploration potential between the two zones.  Company geologists believe the area could contain a significant deposit.

The potential for discovering additional zones of high-grade veins as well as other bulk tonnage deposits within the property position is excellent. During the initial 2006 program, company geologists also completed a reconnaissance evaluation of approximately 30% of the property position. An additional eleven distinct zones of mineralization have been discovered. All of these zones contain prospects and historic mines, some possibly dating back to the Spanish. To date, a total of 79 rock chip samples have been taken by the Company from the additional zones. Most of the workings explored high-grade polymetallic vein systems that locally exceed 10 metres in width. The Estrella Mine 2.2 kilometres southwest of the El Reventon Breccia contains three levels that explored and partially developed northeast and northwest striking vein systems with widths ranging from 2 to 4 metres. Although sampling was limited due to access and limited outcrops, samples reported 0.818 g/t gold and 302 g/t silver over 0.75 metres; 0.222 g/t gold and 100 g/t silver over 4 metres; and 0.372 g/t gold and 100 g/t silver over 1.5 metres. The San Genaro prospect is approximately 2.1 kilometres northeast of the El Reventon Breccia, and is traceable on surface by workings and limited outcrops for a strike length of approximately 400 metres. The workings are presently inaccessible, and there are few outcrops affording exposures for sampling. A sample from a surface exposure reported 0.432 g/t gold and 63.3 g/t silver over a 6 metre width.

An initial stream sediment sampling program was also undertaken with twelve samples collected from various drainages within the property. Very strong silver anomalies were reported in the El Reventon drainage, as well as the Arroyo Portero 2 kilometres northeast of the El Reventon Breccia, and two arroyos 1.8 kilometres southwest and 2.6 kilometres west-southwest respectively from the El Reventon Breccia. A very strong gold anomaly (0.189 g/t) with no silver was reported from a drainage approximately 2 kilometres northeast of the El Reventon Breccia. These results indicate that stream sediment sampling is a very effective tool for reconnaissance exploration within the property and further sampling is continuing.

Geology

The project lies within the Sierra Madre Occidental geological province and a highly prospective mineral belt that includes the mines and districts of Bacis, Montoros, Metates, La Cienega and Topia. The property position controls a series of occurrences aligned along a northeast trending belt consisting of Upper Jurassic low-grade metasedimentary rocks overlain by andesite and rhyolite volcanics belonging to the Inferior and Superior Super Groups. Mineralization may be genetically associated with andesite and dacite porphyry intrusives.

The Reventon Breccia is a high sulfide occurrence hosted within intensely altered andesite porphyry intruding andesite tuff and agglomerate. Outcrops of the porphyry display intense hydrothermal brecciation, with micro and macro breccia textures. The entire exposed zone has strong epithermal silica flooding and replacement within the matrix and breccia fragments. Mineralization occurs as disseminations, veining, stockworking, and aggregates of coarse pyrite, galena and sphalerite, contained within the intrusive as well as the adjacent volcanics.
