Guayabales Project ? Colombia
Tresoro Mining Corp. is developing an initial gold prospect located in northern central Colombia in South America.
The Guayabales gold prospect is located in the Marmato Mining District, a region that has an extensive and productive gold mining history dating back to before the time of the Spanish Conquistadors, and continuing to the present. Security, access, infrastructure and available workforce are adequate to support the development of a mineral deposit at Guayabales due to an active and growing mining industry presence in the area.
The Guayabales property is located on the eastern margin of the Western Cordillera of the Colombian Andes, and occurs within a regional scale structural zone that hosts the productive Middle Cauca Gold Belt (i.e., credited with 16 million ounces of gold resources/reserves and historic production).
The porphyry gold and intermediate sulfidation gold-silver mineralization at Guayabales, and the Marmato District in general, is related to the emplacement of stocks of late Miocene age. Structure is an important control on the mineralization, particularly along northwest trending shear zones.
The geologic relationship of gold-silver intermediate sulfidation to porphyry gold mineralization provides metallogenic context for the exploration targets and 2011 program carried out on the Guayabales project, which is summarized in a NI43-101 report. Tresoro?s principal exploration target is a bulk tonnage, porphyry precious metals deposit that will be potentially amenable to open-pit mining.
A second target type with upside exploration potential is the long recognized, higher-grade vein zones amenable to selective, underground mining exploitation. The potential for defining economic gold-silver mineralization of this style is clearly manifested by the presence of a number of small-scale mining operations on the property.
Mining Colombia
Colombia has produced an estimated 85 million ounces of gold since the Spanish conquest in 1514. There is no reliable estimate of the gold produced prior to, and during the Spanish conquest. In 1937, Emmons estimated production at over 49 million ounces of gold during the post conquest period from 1514 to 1937, making Colombia the largest producer in South America during that time frame.
Recent production has earned Colombia a ranking, which has ranged from 2nd to 5th largest gold producer in South America, and 12th to 20th largest in the world (Ministerio de Minas y Energia, Colombia, 1999-2006). In 2000, Shaw documented additional production of 30 million ounces of gold for the period 1937 to 2000. For the years 2000 to 2004, the U.S. Geological Survey documents additional production of 4.95 million ounces of gold (Bermundez, 2000; Torres, 2004). The Dow Jones Business News Service reported on August 15, 2006 that Colombia had produced 1.5 million ounces of gold in 2005. Approximately two thirds of Colombian gold production has been from placer deposits in the Department of Antioquia, which is immediately adjacent to the Department (Caldas) in which Guayabales occurs.
Everything I say is in my opinion, do your own DD and make your decision wisely! Don't spend more then you can afford to lose!
