|Soltera Mining Developing Historic Argentine Goldmine|
By James West
Some of the largest gold deposits in the world are currently under development in Argentina, a country whose past political problems have precluded the exploration over the bulk of its vast 2.8 million square kilometers.
Barrick (NYSE:ABX) is developing the $2.4 billion Pascua-Lama project, Pascua-Lama has proven and probable reserves of 17.0 million ounces of gold, and contains 689 million ounces of silver, and 565 million pounds of copper, within the gold reserves. It has an estimated mine life of 23 years. Located on the border of Argentina and Chile, this project will benefit from existing infrastructure, processing, staffing, and community development programs at Barrick’s Veladero mine, within ten kilometers.
Soltera Mining (OTCBB:SLTA, Frankfurt: SN7) is also developing a past producing mine with the potential to prove up a sizable deposit.
The El Torno project is located in the Andean Cordillera in the extreme northwest of Argentina near the international borders with Bolivia and Chile. The property consists of five mining rights covering a total area of 7,800 hectares. Soltera has an agreement with the titleholder that includes payments totaling US$350,000 to June 2010 and an obligation to spend US$1 million on exploration during the first two years of the agreement. Various additional payments can be made to extend the exploration period, and Soltera has an option to acquire additional mineral titles.
Historically, El Torno is a large gold-rich quartz vein up to 14 km long and 14 m wide that was worked by the Incas, Jesuits and Spanish and has more than 1,000 m of underground galleries. The vein extends north-south, is sub-vertical, and is accompanied in places by a stockwork system of small quartz and pyrite veins that can extend up to 300 m from the main vein.
The prospect was investigated by Puma Minerals in 1997 who carried out more than 2,100 m of drilling; then by Peñoles in 1999, who undertook trenching, grab sampling, geological surveying as well as a geophysical IP survey. Soltera believes results from these two former exploration programs justify further exploration of the prospect.
Soltera’s management believes a comprehensive exploration program employing modern technologies should result in the discovery of a substantial gold deposit.
During the last quarter of 2007, geochemical stream sediments were sampled to evaluate the presence of mineralization along and around the whole gold-quartz vein system, as well as in specific areas of the stockwork. Soltera is now awaiting the analytical results of these geochemical assays from a Canadian chemical laboratory, the results of which will be announced in February.
In November, the exploration team commenced structural geological mapping and is currently re-interpreting the geological structures associated with mineralization. Evidence to date suggests that the gold-quartz veining is different from previous interpretations and the mineralization could be more widespread than previously thought.
This activity will be followed in the first quarter of 2008 by trenching and geophysical surveys in order to define precise drilling targets for the second quarter of 2008.
The company currently has approx. US$800,000 in the bank. These funds are sufficient to fund exploration through to May 2008. Soltera has commitments from existing shareholders for additional funding for the Spring Drill Program.
Soltera is headed by Fabio Montanari, who joined the company as CEO in August last year.
Dr. Montanari brings to Soltera a distinguished international mining career spanning over twenty-five years. Included is senior experience spearheading advanced exploration and mining activities for a host of internationally recognized exploration and mining companies in North, Central and West Africa, South America, Europe, Canada and the United States. Dr. Montanari's responsibilities have encompassed various mining engineering, operations, pre-feasibility and general management positions, including business development roles at the corporate management level.
Dr. Montanari currently serves as a Director for RGM of Cagliari Italy, an advisory firm specializing in mining exploration, project assessment, and evaluation, and holds a doctorate degree in economic geology from the University of Ferrara, Italy. Additionally, he is the author of a textbook on economic geology, which has been adopted by several major Italian universities.
Other major mines in Argentina include:
• The Alumbrera Mine in Northwest Argentina, owned jointly by Northern Orion (AMEX:NTO), Xstrata PLC (LSE:XTA), and Goldcorp (NYSE:GG), is one of the world’s largest copper gold mines and also one of the world’s lowest cash cost copper producers, with contained copper reserves of 385,000 tonnes of copper and 1.8 million ounces of gold
• The Agua Rica Mine is also in Northwest Argentina, only 34 km from the Alumbrera mine, has drill defined metal inventory of 21.8 billion pounds of copper, 13.3 million ounces of gold and 1.7 billion pounds of molybdenum. Agua Rica is owned 100% by Northern Orion, who was recently the subject of a successful takeover bid by Yamana Gold (NYSE:YAU), who also swallowed Meridian Gold (NYSE:MDG) in the process.
• Marifil Mines (TSX.V:MFM) has a strong portfolio of 34 advanced and early stage exploration projects covering more than 395,000 hectares of prospective ground throughout Argentina. The key targets include both precious metals and base metal finds
near existing mines, as well as in areas that previously have been unexplored.
• Rio Tinto PLC (NYSE:RTP) operates a large potash operation in Argentina, and is also exploring several large areas for precious metals.

|Soltera Mining Acquires Three More Past-Producing Gold Prospects|
By Eric Pratt
Soltera Mining Corp. (OTCBB:SLTA) has been busy acquiring properties during the first quarter of 2008. Unstable markets have been unable to dampen the resolve with which management goes about building shareholder value.
Three weeks ago, Soltera announced it had obtained two new Mexican gold properties through the acquisition of Aztek Mineral, S.A. de CV. One week after that, the vending in of the Eureka Copper-Gold property and joint venture with TNR Gold Corp. (TSX.V:TNR) was announced.
That brings to 4 the number of gold projects under development by Soltera, summarized as follows:
El Torno (Argentina, gold, mining rights 7,863 hectares) is located in the Andean Cordillera near the international border with Bolivia. The property contains a very large gold-bearing quartz vein that extends intermittently for at least 14 km long north-south. The vein is sub-vertical and the gold is concentrated in a 2 meter-thick breccia zone along its western flank.
Historically, El Torno was worked by the Incas and the Spanish over a long period and has more than 1,000 m of underground galleries. There is still a small-scale operation extracting gold from elluvial deposits on the east side of the vein. In 1997, Puma Minerals carried out 2,100 m of drilling on a 1 km length; and in 1999 Penoles Minerals (operators of the world’s richest silver mine and Mexico’s richest and largest gold mines) undertook surface sampling, geological mapping and an IP geophysical survey in the same area. The combined (non NI-43-101 compliant) results of this work showed:
a) El Torno is within a “gold province” that extends several hundred kilometers north-south through Argentina and Bolivia;
b) The strongly mineralized breccia zone on the west side of the vein carries up to 37 gpt gold in the tested area, and has potential for several million ounces along the length of the vein;
c) Samples of stockwork zones some distance from the main vein gave up 23 gpt and in one case 112 gpt gold;
d) There are several IP geophysical anomalies that could indicate mineralization, but have not yet been drilled.
Soltera holds almost all the 14 km length and commenced their exploration in late 2007 with a geochemical stream sediment survey combined with structural mapping designed to target specific parts of the vein and the surrounding area for more detailed investigation.
Soltera will now define drill targets using more detailed geochemical and geophysical surveys. Drilling is scheduled to commence in the second quarter of 2008 and, given success, this will lead immediately to a full feasibility study to commence before year’s end.
Real de Cananea, Mexico
The “Real de Cananea” (Mexico, gold, mining claims 1,030 hectares) is located in Sonora State 26 km from the Cananea copper mine owned by Penoles. It contains a gold-bearing fault zone up to 270 m wide and more than 400m long within Cretaceous volcanic rocks that are intensely altered and carry gold.
There is a small old mine in the center of the property that was probably first worked by the Mayas and certainly by the Spaniards, with several shafts reaching 100 m below surface. The hard wallrock was mined with enormous effort and this, together with the fact that water had to be transported 8 km, indicates the importance of the mineralisation. Gold is widespread on the property, with altered rocks showing up to 65 gpt.
Soltera’s target is a large-scale open-pit and the area is broad enough to accommodate well in excess of 1 million ounces. Geochemical, geological and geophysical surveys will be used to define drill targets and drilling is scheduled for the third quarter of 2008.
(Argentina, copper-gold, around 10,000 hectares) is located in northern Argentina near the Bolivian border and only 3 km from the El Torno project. The property contains ‘Red Bed’ type strata-bound copper mineralization within sedimentary sandstones, clays and conglomerates. The surface exposures are weathered and contain erratically distributed gold. Alluvial gold has been worked in the area since prior to the time of the Spanish arrival and there is an old mine with over 5 km of underground workings that exploited copper and gold on a small scale until 1987.
The deposit is similar in style to major copper deposits in the Bolivian part of the Tertiary Belt. A geological estimate in the late 1990’s (historic resources estimate which is not NI-43-101 compliant) was 50 to 60 million tons grading 1% copper. Only 70 meters of the 450 m deep formation has been explored to date which leaves extensive upside potential.
TNR Gold Corp. (“TNR”), a Vancouver based mining company listed on the TSX with extensive experience in Argentina, has entered into an option agreement with the option vendor to acquire a 75% interest in the property by spending a total of US$3,000,000 in exploration and option payments before April 20, 2010.
TNR will undertake detailed geological mapping, trenching, geochemical and geophysical surveys, sampling the historic underground workings and drilling. Soltera is not required to incur any expenditure on the project at the present time.
Casita Colorada, the Company’s other project in Mexico, is a large mineralized shear zone worked since the end of the 1800’s for gold. The mineralized zone was at least 400 m long and 150 m wide and there is potential for a substantial gold deposit, but the project is being held in reserve so that the company can concentrate on El Torno and Real de Cananea.
Be sure to keep a close eye on SLTA over the next couple months. Geochemical assay results are due any day now, and there’s plenty of news to be generated by exploration activity on all the properties.

|They just posted video of their new gold production plant at El Torno. SLTA has gone from 5 cents to 16 cents over the past three weeks and they are still to announce the start of gold production and imminent financing for more exploration. Check all the info on them at www.twitter.com/SolteraMining It's a good time to take a position in my opinion.|

|SLTA Gold mining in Argentina |
JUJUY, ARGENTINA--(Marketwired - Apr 2, 2013) - Dr. Fabio Montanari, President and CEO of Soltera Mining Corp. (SLTA) (www.solteramining.com), is pleased to announce that the 2012 field programs of bedrock sampling and geophysics on its El Torno property in Argentina produced very satisfactory results.
The 78 square kilometer El Torno property in the high Andes of northern Argentina contains a very large quartz vein system extending intermittently for 14 kilometers. Gold is found in narrow veins both within and outside this main system. The central parts have been worked since the Incas, resulting in about 1 km of underground galleries; and exploration programs in the late 1990s by mining companies, Penoles and Puma Minerals, concluded there is potential for 2 million ounces of gold to a depth of 400 meters (not NI 43-101 compliant.)
