The 100% owned Campanario project is located in Oaxaca State and was acquired through staking by Almaden. The staked claim covers a roughly 10,000 hectare area encompassing several ridges where outcrop and subcrop of a breccia body has been identified, interpreted to be hydrothermal in origin.

 

The outcrop and subcrop of the breccia body consists of fragments of various rocks types but dominated by fine-grained quartz-feldspar porphyry clasts that are variably sized and shaped. The fragments are silicified, adularised, clay altered and quartz-veined. The matrix of the breccia consists of quartz and pyrite and the breccia itself is extensively crosscut by a stockwork of pyrite-bearing quartz veining. The breccia body has been traced in outcrop to be at least 150 by 150 meters in size however, float of breccia material suggests that the body or bodies of breccia may encompass a much larger area.

A part of the breccia system, which forms a conical ridge, may represent a diatreme-type body. In this area past sampling by Almaden has returned significant gold grades including 18 rock-chip samples of subcrop and float that ranged from 0.007 to 3.59 g/t gold and averaged 0.41 g/t gold. A preliminary four line soil sampling program was carried out on 100 meter spaced lines with samples taken every 25 meters. The samples returned gold values from 10 to 525 ppb gold, averaging 65 ppb gold. Almaden plans a work program on the Campanario project consisting of mapping and sampling this autumn.The Campanario Property, located in Oxaca State, was identified and acquired entirely by staking during a reconnaissance program carried out by Almaden in 2004.

April 2006: A program of rock and soil sampling and geologic mapping and an induced polarization ("IP") geophysical survey in order to better define the breccia zone and the soil anomaly has been initiated. [more +]

January 2005: Almaden completes a work program consisting of the collection of 18 rock-chip samples of subcrop and float that have ranged from 7 to 3,590 ppb (parts per billion; 1000 parts per billion is equivalent to 1 parts per million or 1 gram per tonne) gold and averaged 409 ppb gold. A preliminary four line soil sampling program was carried on 100 meter spaced lines with samples taken every 25 meters. The samples have returned gold values from 10 to 525 ppb gold, averaging 65 ppb gold. A greater than 100 ppb gold anomaly that remains open and appears to be expanding in size was identified in the southern most two lines of soil samples. Almaden has initiated a further program of rock and soil sampling and geologic mapping and an induced polarization (IP) geophysical survey in order to better define the breccia zone and the soil anomaly.
