he makes it sound like it was a mistake for AUN to sell. But I assume AUN just wants to concentrate on Shafter.

Silvermex has an option on the San Marcial property, a near-surface deposit of over 20 million ounces of high- grade silver in Sinaloa State. They also just bought the old Rosario Mine from Aurcana Corporation. This is a mine that was operated by Grupo Mexico in the 1990s and was shut down due to labor issues and low metal prices. The infrastructure at Rosario will allow Silvermex to fast-track San Marcial into production. There is also a couple of year's worth of production left behind by Grupo at Rosario that is very economical. There is significant exploration potential at the old mine, at San Marcial and within the district. Either of these projects on their own may not have been developable without a lot more exploration, but together they make a very powerful story and a near term silver producer.
