Gold Mining in Mineral Rich Argentina!

Trommel of gravity concentration plant on El Torno

“More than 7,000 trench samples contained detectable gold, which confirms that a zone of pervasive mineralization occurs throughout the whole central area”

JUJUY, ARGENTINA – Soltera Mining Corp. (SLTA) (, an exploration company that is concentrating on the major El Torno gold project in northern Argentina issues the following update . Dr. Fabio Montanari, President and CEO of Soltera Mining Corp. (SLTA) (, reports that the 2012 field programs of bedrock sampling and geophysics on its El Torno property in Argentina produced the following results.

Previous Soltera geochemical surveys over the whole property indicated that gold mineralization occurred throughout the length of the vein system and in networks of small quartz veins away from the main system. Surface sampling in late 2011 then identified five gold ‘hot spots’ with gold values commonly more than 1 g/t gold, including one channel sample as high as 376 g/t gold over 1.5 meters.

The 2012 sampling program involved taking channel samples of bedrock from the walls of more than 400 surface trenches, and in an existing gallery 20 meters below the surface. The 11,000 samples were each between one meter and one and a half meters long and were analysed at a laboratory of international standing. The sampling was concentrated within a 12 square kilometer area over the central part of the vein system.

A ground geophysical EM-IP survey was also conducted over part of the sampled area and consisted of thirty 2 kilometer-long lines extending east-west and four 4 kilometer-long lines over the main mineralised zones.

The results from these 2012 field programs showed:

More than 7,000 trench samples contained detectable gold, which confirms that a zone of pervasive mineralization occurs throughout the whole central area.
Within this broad zone, there are significant gold concentrations. A total of 541 samples contained more than 0.4g/t gold and, of those, 285 contained more than 1 g/t. Analyses with more than 5 g/t gold from the 2012 sampling program are shown below; all are 1 meter-long chip-channel samples, this data has not previously been published: Newswire
All the gold occurs within veins of heavily fractured quartz often associated with iron oxides. These veins can be up to 2 meters thick or be in the form of fine networks within the bedrock. They all appear to be later than the main vein quartz system and represent a late stage pulse of mineralized solutions that penetrated along fracture zones.
An area of 2 square kilometers over the central part of the main quartz vein system has been defined for priority test work and includes four of the five gold ‘hot-spots’ identified in the earlier sampling programs. An additional highly prospective area occurs one kilometer to the west of the main veins.
The geophysical EM-IP survey showed several strong near-surface anomalies that could well indicate conditions suitable for mineralization and are ideally suited for drilling.

We now have considerable data about gold on the surface, but very little about it at depth. Old workings and the 1990’s drill holes show that gold occurs to at least 100 meters below surface, but drilling is absolutely essential to ascertain its quantity and distribution. A drill program is being planned.
