Apogee Silver Ltd. reported assay results from 21 diamond drill holes of the silver oxide program at Pulacayo.
The drilling program was undertaken to delineate near surface silver oxide resources above the sulphide resources at Pulacayo. All of the holes were drilled from surface. A few highlights from the first set of drilling results from the program include: - 11PUD220 intersected 20.8 meters grading 79.3 g/t silver, from 35.2 to 56 meters and 9.0 meters grading 119.7 g/t Ag, from 80 to 89.0 meters.
- 11PUD221 intersected 30.0 meters grading 129.0 g/t silver from 37.0 to 67.0 meters.
- 11PUD233 intersected 9.0 meters grading 130 g/t silver from 20.0 to 29.0 meters, and 6.0 meters grading 186.7 g/t silver from 104.0 to 110.0 meters.
- 11PUD239 intersected 19.0 meters grading 67.2 g/t silver from 71.0 to 90.0 meters.
- 11PUD240 intersected 23.0 meters grading 50.20 g/t silver from 31.0 to 54.0 meters, including 6.0 meters grading 109.3 g/t silver from 48.0 to 54.0 meters.
The silver oxide drilling program was initiated following successful metallurgical testing on composite samples from existing drill core at Pulacayo. The metallurgical tests were designed to determine silver mineralogy in the oxide zone and its amenability to recovery by conventional cyanide leaching. Seventy-two hour leach tests with various reagent additions indicated that silver dissolutions of 77% to 81% can be achieved. Chris Collins, P. Geo., President of Apogee, states, "We are very excited by the first set of assay results from the silver oxide diamond drilling program at Pulacayo. These results confirm that the extensive silver lead zinc mineralization associated with the main Veto Tajo Structure at the Pulacayo Deposit continues through the oxide zone to the surface. These results coupled with positive results from oxide zone metallurgical testing undertaken last year offer excellent potential for a significant increase in silver ounces in resources at Pulacayo with the addition of oxide zone mineralization. A further potential benefit is that oxide zone mineralization would generally be amenable to lower cost mining and leaching methods." More information, click here. |
