Canamex Resources Corp.: Airborne Geophysical Survey at Aranka North Property in Guyana Yields Fifteen Large Anomalies for Fo...

Canamex Resources Corp. (the "Company") (TSX VENTURE:CSQ)(FRANKFURT:CX6) is very
pleased to report on the preliminary results of interpretive work being
performed on airborne magnetic and radiometric data acquired over the Aranka
North Property in Guyana by International Geophysical Services, LLC in Lakewood,
Colorado.
The initial interpretive work has identified fifteen large, discrete anomalies,
all of which have dimension of 2-4 kilometers long and 1-3 kilometers wide
within larger shear zones. Two strong NE-trending shear zones are identified in
the airborne magnetic data, which juxtapose granitic rocks against
metasedimentary and metavolcanic rocks, are similar to the host structural
environment of the major shear-zone hosted gold deposits in Ghana. Ghana boasts
production and current reserves of over 120 million ounces of gold from shear
zone hosted gold deposits. The geology in Ghana shares similar characteristics
with the geology in Guyana, the two terrains having been separated from one
another by rifting that formed the Atlantic Ocean. In addition, there is a
strong E-W shear zone and a NW-trending shear zone that extend across the entire
property that also juxtapose granitic rocks against metavolcanic and
metasedimentary rocks, which bear similarities to the shear zones that host some
of the major multi-million ounce gold deposits in Guyana (Toroparu, Omai) and in
adjacent Surinam (Rosebel).
All of the discrete anomalies are defined by high potassium readings within
otherwise potassium poor metasedimetary and metavolcanic rocks and occur along
the major shear contacts with a granitic batholith. Sericite alteration is a
common feature of the gold deposits in these shear zone hosted terranes, and
potassium is a major component of the sericite. These anomalies tend to occur
along the southern margin of a large granitic body that continues off the
geophysical survey block to the north and east. The granite is shaped like a
southward facing prow; a shear zone forms one of the flanks of the prow, with
potassium anomalies appearing to emanate from the prow of the granite.
The British Geological Survey commented on the gold deposits in Guyana in 1938:
"...the contact and near-contact (gold) deposits which form an important
proportion of the goldfields of the Colony (now Guyana) occur mainly along the
southern margins of batholiths e.g. Aranka, Aremu, Pipirni, Tamakay and
Issineru. There would thus appear to be some additional structural control which
determines the provenance of this type of mineralization (along the southern
contacts of the granites)...".
The majority of the geophysical anomalies at Aranka North match this historical
description extremely well.
International Geophysical Services LLC ("IGS") will continue to interpret the
airborne geophysical data, as there are many more smaller-sized anomalies to
select and prioritize. However, the work completed to date is sufficient to
prioritize the top fifteen anomalies for follow-up work. All of these anomalies
lie within the central portion of the airborne survey flight block, and it is
the recommendation of IGS that the central portion of the flight block be flown
with a helicopter airborne EM system to map resistivity in these anomaly areas
and identify the presence of sulfides where possible. Resistivity lows and
sulfides characterize most of the gold deposits in the Precambrian shear zone
hosted gold deposits in Ghana and Guyana.
A helicopter EM system is currently in Guyana, and the Company will attempt to
arrange an airborne EM survey over the central portion of the land package once
the interpretations of the existing geophysical data are final and a follow-up
survey has been designed.
Additionally, access reconnaissance has demonstrated we have unfettered river
access to the heart of the land package up the Waini River, with an excellent
camp site along the river bank located near the southern tip of the granite
body, in proximity to the top priority fifteen anomalies referenced above.
Geotech Airborne Surveys was the prime airborne geophysical contractor to GMV
Minerals Inc. ("GMV"). Chris Campbell of Intrepid Geophysics provided survey
planning and oversight along with QCQA services to GMV and processed the data.
Canamex purchased the processed data from GMV as part of its Option and Joint
Venture Agreement with GMV (see July 6, 2011 press release).
