Canasta Dorada - Sonora, Mexico |
|
|
|
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.
Significant gold mineralization has been outlined in 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. Silicified and veined low angle
structures within dirty sandstone, shale, and felsic intrusives are exposed
within the area. The mineralized zone is exposed over a vertical thickness
of approximately 50 m within the 200 m x 375 m area. Chip sample lines
such as: 19.8 m @ 2.8 gpt gold and 34.8 m @ 1.04 gpt gold indicate the great
potential of this prospect for large scale surface mineable mineralization.
