Interview with Mining Expert David Bond regarding his site visit to Soltera's El Torno Project [PDF]

Soltera Mining Corp. (OTCBB: SLTA)

(Frankfurt Stock Exchange: SN7)
 

World-class technical leadership with highly prospective claims

Soltera Mining Corp. is a relatively new issue to the markets, listed on the US OTCBB (ticker symbol SLTA) and on the Frankfurt Stock Exchange (ticker symbol SN7). Soltera has come to our attention, in part, due to the highly qualified management teams success in mining and the exceptional prospective nature of Soltera's flagship El Torno project in Northern Argentina that has the earmarking of a significant gold mine.
 
      Soltera Mining Corp. is an aggressive exploration stage company with gold and base metal properties in Argentina, Canada and Mexico. Three recent important developments have occurred on Soltera's Argentina and Mexico projects which are the principle focus of Soltera:

1) El Torno property - major gold exploration project in Argentina: El Torno is a large gold-rich quartz vein up to 14 km long and 14 m wide with an identified 2 km section containing a gold-rich zone on the western side of the vein carrying up to 37 gpt (grams per ton) gold and identified stockwork systems in the country rock with up to 112 gpt gold (based on previous non-NI-43-101 compliant reports). El Torno possesses large-scale potential for both underground and open-pit mining, with fast-tracked feasibility study potentially by year-end. Geochemical and structural survey results released this April corroborate large-scale open-pit gold target potential.

2) Casita Colorada & Real de Cananea gold projects - Sonora Mexico: Soltera recently added these two past-producing gold properties in Mexico with potential for more than 1 million oz gold centered on old mines.

3) Eureka property - copper-gold project in Argentina: This recently acquired project has previous (non-43-101 compliant) resource estimate of 50-60 Million tons at 1% Cu.

El Torno Project

New Geochemical & Structural Results Corroborate large-scale open-pit gold target potential

       Soltera's El Torno gold prospect is a past-producing (historic) gold project that has been the focus of exploration efforts by Soltera's President, Dr. Fabio Montenari. SLTA believes that modern exploration techniques will allow for the further extraction of gold from this historic past producing area and new geochemical and structural survey results ([See Apr 14/08 Release] & [See Apr 16/08 Release]) move the Company a major step forward towards this reality.

Interpretation by SLTA's management: "The results show a series of distinct, very strong anomalies extending the full 14 km length of the vein system, and also up to 2 km away where they appear to be centred over large areas of vein suites and stockworks in the country rocks. One of these anomalies alone is 2 km long by 1.5 km wide. This indicates that the gold mineralization is far more extensive than previously thought and offers the distinct possibility of wide mineralised areas of country rock that could form previously unrecognised large-scale open-pit targets."

President and CEO, Dr. Fabio Montanari, stated, "Based on previous sampling and drilling by Penoles Minerals and Puma Minerals in the late 1990s, a report was done in 2000 entitled Considerations Regarding The El Torno Prospect clearly delineating a 500,000+ ounces gold opportunity on a portion of the property and then goes on to extrapolate these results over the rest of the strike zone to conclude that there may be a 2,000,000+ ounces of gold potential at El Torno. The report also states that the geological structure is similar to those at the Bendigo and Ballarat goldfields in Australia, which have each produced in excess of 20,000,000 ounces of gold. I want to stress that the report and the previous work done are non-NI-43-101 compliant but having said that, when you add the recently announced geochemical and structural survey results which not only appear to expand on the main vein system but have also identified brand new and very large strong anomalies, we feel that the previous conclusions of the report could be substantially increased. Our objective is to have the El Torno gold project ready to start feasibility studies by the end of 2008."

       The property, consisting of mining rights covering 7,863 hectares, contains a 14 km long north-south quartz vein system that cuts metamorphosed sedimentary rocks. A central part of the vein shows old workings, and drilling by Puma Minerals and Penoles in the late 1990s over about 1 km discovered a gold rich zone on the western side of the vein carrying up to 37 gpt (grams per ton) gold and identified stockwork systems in the country rock with up to 112 gpt gold.
 
       Soltera undertook stream sediment sampling throughout the whole property as a first check to establish whether only the central part of the vein system was gold-rich. The country is rolling highland dissected by streams, so is well suited for this type of survey. A total of 596 samples were collected at selected locations on stream courses and the -80 mesh fractions analysed in Canada.
 
       The structural study concentrated on parts of the main vein system exposed at surface and in the old mine workings. The results suggest that the structure is broader and more complex than the simple vertical vein interpreted by previous workers. In fact, the re-interpretation suggests that the gold-bearing quartz could be concentrated in anticlinal structures, rather similar in character to those of the Bendigo and Ballarat gold fields in Australia. This opens up the possibility that the mineralised system could be much more extensive than previously thought and that there may be repetitions of the vein at depth. If this proves correct, the earlier non NI-43-101 compliant Penoles Minerals estimate of more than 500,000 ounces of gold to 100 metres depth could be increased very substantially.
 
       More detailed geochemical surveys will shortly be underway to define more precisely the anomalies, and these will be followed by geophysical surveys to define precise drill targets.

 
Infrastructure on the El Torno Project is very good as the area is accessible by road all year round, and on the property there is a gravity concentration plant, a guest-house with 6 bedrooms, 2 bathrooms and four other rooms, a warehouse with two electric generators, water pumps and other facilities. Water is abundant in a nearby river.

 
Going forward - More detailed geochemical surveys will shortly be underway on El Torno to define more precisely the anomalies, and these will be followed by geophysical surveys to define precise drill targets.
