Timmins Gold announces that a 3,000 thousand meter core drill program has commenced on the Company's high grade Las Coloradas Project located in Durango, Mexico. The objectives of the drilling program include the exploration of the projection of the Las Coloradas mineral structures along strike and at depth where historic mining operations reported grades ranging from 15 to 50 grams of gold and 1kg of silver. The drill program is also designed to test the extent of disseminated mineralization in the host rock.
11 holes varying in depth from 200 to 450 meters are programmed along the 4.5 kilometers of the main mineral structure. The first 3 holes are designed to explore beneath the mineral zone known to exist at the bottom of the present underground workings in the Piedra Bola and Santa Anita shoots. This area covers a length of 1,500 meters and a depth of up to 350 meters. In the Escandalo-Los Fresnos and Verdun-El Tajo areas, the drilling is designed with similar objectives, and also to explore the possibility of a bulk tonnage zone in the host rock in the footwall of the main structure.
A preliminary exploration program was undertaken by Timmins Gold in the second half of 2007. An area 5 kilometers long and 2 kilometers wide was geologically mapped and 127 chip samples were taken along the main mineral structure, from the host rock, the dike and in secondary mineral structures parallel or intercepting the main structure. The highest value in the present surface sampling was 6.737 g/t Au and 456 g/t Ag over a width of 1.50 meters.
Old mining works like tunnels, shafts (both of which are currently non-accessible), trenches and small pits are found in four areas located along the main mineral structure. The most important drill targets as evidenced by the existence of old underground mining operations are the Santa Anita and La Piedra Bola areas, located in the north portion of the surveyed area. Both areas are old ore shoots with historic mining operations with grades varying from 15 to 50 g/t Au and more than 1 kg/t Ag. Other two important zones located at the south portion of the main mineral structure are El Escandalo-El Fresno and Verdun-El Tajo. In the El Escandalo-El Fresno area the sampling in the vein returned values varying from 0.50 to 0.808 g/t Au and 80 to 140 g/t Ag, but the host rock in the footwall averaged 0.53 g/t Au and 39 g/t Ag, in a width of 30 meters. The host rock in this area looks very altered, mainly kaolinization and propilitization with regular dissemination of fine pyrite, epidote and chlorite.
The Las Coloradas gold and silver mineral structure is exposed along more than 4.5 kilometers with a general strike of N15°W and a dip of 70° to 80°NE with widths varying from 1 to 6 meters. The structure consists of a strong shear zone in which a porphyritic feldspar dike, probably of andesite composition has been emplaced. This forms the contact between volcanic rocks of dacitic composition of the Upper Volcanic Series and andesites of the Lower Volcanic Series. The gold mineralization is hosted in a breccia in the hangingwall and footwall of the dike and within the dike in the form of quartz veinlets. Disseminated pyrite and iron oxides are the main minerals observed on surface in the breccias and in the host rock, which is marked by a wide zone of argillization with white quartz stockwork and iron oxides (limonites, goethite and hematite)
