Diamond drilling by KGL Resources at the Marshall, Reward, Green Parrot and Bellbird deposits of the Jervois Copper-Silver-Gold Project in Australia’s Northern Territory has confirmed shallow, high-grade mineralization. The drilling has also provided material for further metallurgical test work.
Reward results include 23 metres from 29 metres @ 1.68% copper, 21.3 grams/tonne silver and 0.4 grams/tonne gold, and 3 metres from 58 metres @ 3.02% copper, 0.13% lead, 0.87% zinc, 26 grams/tonne silver and 0.22 grams/tonne gold from one hole; and 5 metres from 29 metres @ 1.08% copper, 18 grams/tonne silver and 0.16 grams/tonne gold, and 12 metres from 40 metres @ 3.47% copper, 0.36% zinc, 44.4 grams/tonne silver and 0.91 grams/tonne gold in another hole.
At Marshall best result was 8 metres from 20 metres @ 4.58% copper, 0.37% lead, 0.14% zinc, 89 grams/tonne silver and 0.51 grams/tonne gold. Green Parrot returned 6 metres from 14 metres @ 1.3% copper, 0.71% lead, 0.27% zinc, 104.5 grams/tonne silver and 0.82 grams/tonne gold, and 7 metres from 22 metres @ 2.84% copper, 2.32% lead, 0.4% zinc, 158.9 grams/tonne silver and 0.04 grams/tonne gold.
At Bellbird one hole returned 12 metres from 41 metres @ 1.48% copper, 10.8 grams/tonne silver and 0.13 grams/tonne gold, while another hole returned 4 metres from 18 metres @ 2.73% copper, 7.5 grams/tonne silver and 0.2 grams/tonne gold, and 9 metres from 53 metres @ 5.57% copper, 44 grams/tonne silver and 0.19 grams/tonne gold.
On February 14 Mitchell Services began a 9000 metre RC drilling program focused on the Marshall-Reward and Bellbird resources.
During November and December of 2014 a total of 10 metallurgical holes were drilled with at least two holes within each of the main deposits to provide material to enable further test work. The test work program commenced in January and is designed to optimize the recoveries of base and precious metals in the high grade transitional zone.
This also includes comminution test work to confirm throughput rates of the transitional ore in the crushing and milling circuit in addition to providing important information of the structure and density of the ore.
KGL’s managing director Simon Milroy says, “We continue to see good grades in base and precious metals in this drilling program. Most of the drilling within the transitional zone has been RC and this diamond drilling provides important validation of the previous drilling.”
