ENCOURAGING drilling results from Harmony’s Kili Teke prospect have highlighted exploration potential for the company in the Hela province, Papua New Guinea.
Harmony’s wholly owned Kili Teke prospect returned porphyry style mineralisation with highly significant copper-gold intercepts, the company announced in late July.
The footprint of the mineralised zone on the prospect was defined as being over 600 metres of strike, in excess of 200 meters wide, and as extending 700 metres below surface.
More upside potential exists with mineralisation being open at depth and along strike, Harmony said.
Drilling to scope out the extent and geometry of the system remains ongoing.
Harmony chief executive Graham Briggs was encouraged by the results and likened it to OK Tedi and Freida River.
“The latest drilling results from Kili Teke are extremely encouraging and confirm that this asset is yet another fantastic copper-gold find by Harmony in Papua New Guinea.”
“The mineralised footprint is growing as the drilling progresses, and the grades we are seeing are similar to OK Tedi and Frieda River – with zones of higher grade stockwork mineralisation and intervals of mineralised skarn breccia developing within the broader envelope.”
“In a world were new discoveries are rare, we are encouraged by the prospect that Kili Teke could we develop into another major copper-gold discovery,” Mr Briggs said.
At least one intercept from drilling on the prospect correlated with intervals of intense quartz vein stockwork, Harmony announced.
Finding bornite (Cu5FeS4) as part of the copper sulphide assemblage in this area was also highly significant, indicating a potential vector to the higher temperature, higher-grade core of the system.
Harmony said the location fo that mineralisation, together with others, outlined a zone of higher grade mineralisation developing within the broader 0.2 per cent copper shell, which remains open off the grid to the north.
