STRONG copper mineralisation has been intersected between two previous high-grade copper intersections at the Rockface prospect on KGL Resources’ Jervois Copper-Silver-Gold Project in the Northern Territory. One hole encountered a broad zone that includes more than 24 metres of strong copper mineralisation from 435.6 metres.

This hole was targeting Down Hole Electromagnetic (DHEM) conductors 2, 3 and 4 in a 105 metre zone that separates the two previous holes. These holes returned 16 metres @ 3.34% copper and 10.5 metres @ 8.76% copper.

Assay results from the latest hole are expected to confirm visual inspection of the diamond core. The hole has confirmed the continuity of the large Conductor 3 anomaly that has a vertical extent of approximately 350 metres.

It intersected 54.9 metres of mineralisation associated with the conductors. From 411 to 435.6 metres, there is a broad zone of weak stringer mineralisation with disseminated pyrite and chalcopyrite in a moderately to strongly altered garnet-magnetite alteration assemblage. From 435.6 metres, massive and semi-massive chalcopyrite-pyrite has been observed in an intensely altered magnetite host rock. The footwall of the mineralised zone is characterised by a very narrow (20cm) garnet alteration zone.

The hole also intersected a zone of weak mineralisation from 382.6 to 396.2 metres characterised by intense garnet banding with minor disseminated and occasional veined pyrite and chalcopyrite.

DHEM surveying has proven successful in locating high-grade copper at Rockface where grades have generally increased as drilling goes deeper.

KGL chairman Denis Wood said, “The latest result has increased the board’s confidence in using DHEM surveying to identify drill targets. Again, there has been a strong correlation between the conductors from DHEM surveying and the actual drill intersections. This cost-effective technology is proving important in our strategy of increasing and upgrading the total resource at Jervois to world-class, low-cost status.”

He said with high-grade copper mineralisation in the magnetite-chalcopyrite zone responding well to DHEM, a planned survey would assist in targeting additional drilling into the highest grade mineralisation. “The survey should further refine the size and location of the conductors intersected in and adjacent to this hole.”

KGL recently received a further R & D Tax Incentive refund of $2.1 million, bringing total recent refunds to $3 million. The government program reimburses part of eligible research and development expenditure.
