ON EXPLORATION

  • Sable Resources Ltd. completed a leach test on core from the first phase drilling at its Margarita project in Chihuahua. The purpose was to investigate the response of three samples (684, 341, 149 gpt Ag) to silver leaching with cyanide in a bottle roll test. The two higher grade samples had a recovery of 70 and 71 percent Ag after 48 hours, while the lower grade sample had a recovery of 37 percent on the same time lapse. The second stage drilling at Margarita initiated in January, consisting of a minimum of 19 holes for a total of 3000 m, to test extensions and infill of the Margarita vein and the Marie, Juliana, Fabiana and El Caido veins. Six holes have been completed, with a best vein intercept of 12.4 m starting at 30.9 m. Sable received title for the Manzana II application, reducing the size to 39,396 hectares in 11 concessions. Vinata is a drill-ready low-intermediate sulfidation project within these concessions, in which a series of quartz veins outcrop along a strike length of about 1,150 m in volcanic rocks. “The system consists of multiple sub-parallel veins and stockwork zones over a width of between 15m and 170m. Individual veins vary in width from <1m up to about 12 m><1 m up to about 12 m”.
