DRILLING at the Rockface prospect of KGL Resources’ Jervois Copper-Gold-Silver Project in the Northern Territory has delivered high grade copper results. Although only a limited number of deeper holes have been drilled there are early indications of improving copper grades at depth.
Assay results have confirmed the high grade copper mineralisation observed in the core. Significant intersections from one hole were 9 metres from 284 metres @ 2.91% copper, 17.6 grams/tonne (g/t) silver and 0.2 g/t gold, and 6 metres from 296 metres @ 1.6% copper, 9.3 g/t silver and 0.16 g/t gold.
Two holes in the recent campaign were designed to intersect off-hole electromagnetic (EM) conductors modelled below a hole drilled in 2015 that intersected 13 metres from 255 metres @ 2.14% copper and 12.5 g/t silver, and 2 metres from 278 metres @ 2.83% copper and 10.8 g/t silver.
The two recent holes were drilled 50 metres apart to test a second DHEM conductor and both intersected a broad zone of massive magnetite-chalcopyrite. The width and grade of the mineralisation is showing good continuity between the three holes drilled and assayed to date.
Elsewhere at Jervois higher copper grades are generally associated with higher gold grades and that is also evident at Rockface.
One of the recent holes was the deepest at Rockface thus far and intersected 16 metres from 362 metres @ 3.34% copper, 16.7 g/t silver and 0.17 g/t gold. It was just above the large Conductor 3 target that will be tested in a future drilling program.
Rockface prospect is 1.2km southeast of the Bellbird resource at the southern end of the Jervois ‘J-Fold’. It is on a mineralised trend that extends for 12km from Bellbird in the west to Cox’s Find, Green Parrot and then north to the Marshall-Reward resource.
KGL has implemented a scaled-back but highly targeted, technology driven drilling program in response to the current period of low commodity prices. Directors are pursuing a strategy of increasing and upgrading the Jervois resource to position it among the world’s lowest cost copper projects before proceeding to development.
To fund the 2016 exploration KGL completed a $3 million capital raising. As well as the Rockface diamond holes, the company has carried out RC drilling at Green Parrot, a shallow RC program targeting new prospects on the exploration licence and a gravity survey.
