Vancouver — The first four holes of a third round of drilling on the Gold Mountain zone near Nelson, BC has returned wide intervals of low-grade mineralization for Sultan Minerals (SUL-V).
Collared on the Kena property, the latest holes covered a 400-by-100-metre portion of a 1.5-km-by-500 metre coincidental geophysical and geochemical anomaly. The best hole of the four was hole 8, which returned a 2-metre section running 172.1 grams gold per tonne. When this interval was cut to 34.29 grams gold, a 207.6 metres interval from 6.7 metres down-hole averaged 0.92 gram gold.
Hole 9 was collared 75 metre back of hole 8 and cut 0.31 gram gold over 193.6 metres from 3.7 metres down-hole. Moving a further 75 metres back, hole 10 yielded 0.26 gram gold over 178.6 metres from 6.7 metres down-hole. Included in this section was a 2-metre section running 6.54 gram gold.
Hole 11 was collared 100 metres to the north and cut 0.37 gram gold over 345.64 metres from 1.8 metres down-hole. Included in this interval was a higher-grade section averaging 5.53 grams gold over 2 metres. This hole hit intermixed intrusive and volcanics to a down-hole depth of 338 metres when the hole entered the footwall volcanics.
The junior aims on drilling 21 holes during the latest program testing the extent of the gold mineralization over the entire anomaly. The first two rounds of drilling covered a 200-by-300-metre section of the anomaly with hole 1 returning 106 metres grading 1.16 grams gold.
Preliminary petrographic and alteration studies on the drill core has not only confirmed that the mineralization is consistent with a porphyry gold depositional setting (known for large tonnage deposits), but also that it contains very low values of contaminants such as arsenic, cadmium and lead. Initial metallurgical test work on two composite core samples show that the ore is not refractory with recoveries hitting 92-to-97% using cyanide leaching.
