Almaden's 100% owned El Cobre is a copper-gold porphyry target on the east coast of Mexico, 75 kilometers northwest of Veracruz city. The project is road accessible and is located in an area of unparalleled infrastructure, near to a power plant, highways and rail systems.

The 7,500 hectare claim block covers copper-gold porphyry mineralization known to exist over a strike length of at least four kilometers.

The area has been tested by geochemical analysis (rock, soil, & stream), induced polarization (IP) geophysical surveys, magnetics, and drilling, which has indentified several exciting targets. [read more on El Cobre drilling] In addition, geophysical testing over the entire area has shown that the high chargeability roughly corresponds with targets. The highest chargeability occurs at depth, which suggests deeper drill holes should intersect higher anomalous values.

 

 

 

"We are very excited to be drilling at El Cobre, a world-class gold-rich porphyry exploration target. El Cobre is one of the most important assets in our portfolio and we want to advance this project aggressively."
J. Duane Poliquin, Chairman of Almaden

Map above shows the entire claim (blue outline) with work completed including IP lines, soil geochemistry (ranges by copper), and magnetics. Map below highlights areas of high magnetic response along with gold and copper soil anomalies. Please click maps for larger view.

GEOLOGY: Copper-Gold Porphyry [read more about epithermal systems in geoskool +]

Porphyry mineralization is associated with the exposed portions of diorite stocks which have intruded intermediate volcanic rocks. Mineralogic and fluid inclusion studies show conclusively that the gold and copper-gold porphyry-style mineralization at El Cobre is not deeply eroded and great potential exists at depth. More importantly these studies indicate that the mineralization is genetically uniquely like that of some of the Maricunga district gold-copper porphyry systems in Chile.
