Rochester Resources has acquired a 70% interest in the Santa Fe gold-silver property located 6km east of its Mina Real Milling facility in Nayarit, Mexico. The property covers approximately 3800 hectares, and previous work has identified ten zones of epithermal veining and mineralization on the property.
Santa Fe is the Company's highest priority exploration target; the Company will be implementing a 3000 metre diamond drill program and an 800 metre drift
development program at Clavellinos and several other parallel vein systems. The Company believes there is significant potential to discover a stand-alone deposit capable of supporting its own mill. In addition, the Company has identified 26 other vein systems across the Santa Fe property with several vein systems striking greater than 4 kilometers traced along surface. Of note, the "Clavellinos" vein system, at its north end, has a 40 meter wide mineralized alteration zone with three sub-parallel high-grade epithermal veins emplaced within, including a horizon potentially up to 700 meters (twice the horizon found at the Florida Mine). 4+ kilometers away at the south end, the Clavellinos vein system has variable widths between 5 meters and 8 meters traced at surface.
The work to date has better defined the three main vein systems, all of which trend northwesterly and are sub-parallel with some cross veining. From west to east, these are the Jonas system, the Clavellino system, and the Tajitos system.
"Based on my extensive working years in sourcing, developing and operating gold and silver mines in Mexico, the following summary results lead me to believe that we have uncovered a major system of high-grade epithermal veins with areas of multiple parallel veins and some intervening mineralization. There is a strong possibility that these systems contain significantly more potentially economic gold and silver mineralization than has currently been identified." concluded Dr. Parra.
Clavellino Vein System
Of the three, initial indications are that the Clavellino system is the most extensive, having been traced over a length of more than 3 kilometres. The width of this structure varies from 1 metre to 40 metres. At the south end, multiple quartz veins occur over a width of 30 to 40 metres, with mineralization in the intervening wallrocks. At the north end (El Picacho), the vein structure is more discrete, consisting of a 5.4 metre wide zone of silicification.
Two samples taken from old surface workings in the Tepehuaje section of Clavellino returned a grade of 2 grams/tonne of gold and 235 grams/tonne of silver over a 1.6 metre average width.
Jonas Vein System
Sampling along new exposures created by recent road building has exposed the Jonas system in a number of places. Jonas is a silver-rich system, with one main and several subsidiary northwest-trending quartz structures. Continuous sampling has shown that silver values are not just confined to the main veins and occur in some of the intervening altered volcanic wallrocks. Sampling to date on the main level has defined three parallel zones grading up to 162 g/t silver over 2.40 metres and 378 g/t silver over 0.62 metres. Individual sample results for gold range from less than 0.03 g/t to 3.6 g/t and silver from less than 3 g/t to 796 g/t, which includes samples taken from the intervening rock.
Tajitos Vein System
The Tajitos system is relatively narrow (1-1.5 metres true width) exposed in a series of old workings, but well mineralized over more than 300 metres of the 700 metre length identified to date. A sample from the north end of the system produced 4.68 g/t gold and 1,380 g/t silver over 0.7 metres width.
