(MENAFN - ProactiveInvestors - Australia) Argentina Mining (ASX:AVK) has uncovered the potential for high grade gold at its San Francisco gold-silver project in Argentina following the completion of a fourth phase of mapping and sampling of Las Lenas quartz reef.
The sampling of the Las Lenas quartz reef continued to indicate large scale, high grade epithermal gold mineralisation potential with visible gold noted in hand specimen.
The specimen was noted 25 metres north of the previous intercept of 36 metres at 1.23 grams per tonne of gold and 4.85g/t of silver.
A total of 91 rock channel samples have been taken from cross-cuts of the main reef, at 10 metres strike intervals along the strike of a 1,000 metre long section of the central reef.
Induced polarisation pole/dipole array geophysical survey has been scheduled for March, which will define reef depth extent and orientation.
The geological mapping is also underway and the data will be intergrated to assist the geophysical survey.
The central reef of the Las Lenas reef forms the principal component of a 3,700 metre long NNW-trending, epithermal quartz-geothite multiple-reef system, which along with the sub parallel quartz reef and intervening country rocks, attains a width of up 100 metres in certain areas.
Argentina Mining is exploring in five gold and base metals projects in San Juan province in Argentina.
These projects range from the established porphyry copper-gold-molybdenum project at Cerro Blanco, epithermal vein gold and copper mineralisation at Amiches, San Francisco and Tres Amigos.
There are also regional exploration projects near Barrick Gold Corporation's major Veladero gold project with a 12 million ounce gold reserve and the 17.8 million ounce Pascua-Lama operation.
