The Campanario Property, located
in Oxaca State, was identified and acquired entirely by staking
during a reconnaissance program carried out by Almaden in 2004.
The staked
claim covers a roughly 10,000 hectare area encompassing several ridges where outcrop and subcrop
of a breccia body has been identified.
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.

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. [more +]
