The Canasta Dorada
property is located in the northwest corner of the State of Sonora, Mexico,
near the town of Caborca, in the province extending from southern California
through northern Sonora along the Mojave-Sonora Megashear. Mines in this
well-established trend known as the Sonora Gold Belt, which includes
Mesquite (5,000,000 oz), Picacho (500,000 oz) and Padre-Madre in the Yuma
area of extreme southwestern Arizona and southeast California, and La Cholla
(350,000 oz), La Herradura (3,000,000 oz), and Chanate (+500,000 oz) in the
Caborca region of northwest Sonora, Mexico. The property is approximately 28
kilometres north of Caborca, approximately 285 km north of Hermosillo, and
is approximately 190 km southwest of Tucson, Arizona. The Canasta Dorada
gold property consists of a total of seven concessions, covering 448 square
kilometres.
Exploration and discoveries of gold mineralization throughout northwest
Sonora has increased since 1990. Many of the new deposits currently being
mined exploit low grade, micron size, disseminated mineralization along a
northwest-trending zone characterized by traces of the Mojave-Sonora
megashear, a broad northwest-striking structural zone, and northeast
regional thrusts and associated tear faults in the northwestern portion of
the zone. Deposit types include veins and breccias, discontinuous quartz
veins, carbonate sedimentary-hosted deposits and several structurally
controlled deposits. Mineralization is hosted by a wide range of rock units,
including Proterozoic gneiss, Paleozoic sedimentary rocks, Late Jurassic
granitic rocks and Cretaceous clastic and carbonate units. Recent erosion of
pre-existing terrains and alluvial deposits have resulted in locally
extensive Late Tertiary placer gold deposits near Caborca.
High Desert Gold
Corporation ( “Company”) completed a +5000 metre (“m”) diamond drilling
program on the property in 2008 which suggests there is potential for
significant gold mineralization on the property. Gold mineralization at
Canasta Dorada is hosted by Jurassic sedimentary rock units along low-angle
structures and thrust faults, and in areas where high-angle faults, shear
zones, and stockwork veining cut sedimentary and intrusive rock units. Much
of the Canasta Dorada property is covered by colluvium and pediment cover,
and soil and stream sediment sampling have defined geochemical anomalies
that target areas of gold mineralization. The majority of the work
conducted by the Company since 2006 has focused on three targets, the Big
Pit, an extension to the Southwest, Pique Viejo, and the Placer areas, but
there are additional targets that occur within 448 square kilometres (“sq
km”) that comprise the Canasta Dorada property.
The High
Desert Gold drill program was successful in outlining gold mineralization in
the Big Pit area where the gold is hosted in a low angle structural zone.
These drill holes outline an open ended area extending 400x200 metres.
The average
mineralized width and gold grade the Big Pit Area is 15.5 metres @ 0.7 g/t
(0.0225 oz/t).

Drilling was also conducted in the Placer Area, where 2 holes were completed. This area was the
focus of historic dry placer workings where local camposinos dug small pits
along the flanks of the hill and processed the material for gold. The two
holes drilled in this area returned the following results:

HDG believes these are significant intercepts and should be
followed-up with several offset holes.
Surface rock chip sampling
has generated significant gold mineralization over an area measuring
approximately 200 m x 375 m with the average gold grade of the 143 samples
collected from this area being 1.2 gpt Au.
Some
of the values obtained in the rock chip sample program are listed below:
