KGL Resources (ASX:KGL) has logged a record copper intercept of 61.4% Cu during diamond drilling at the Rockface prospect within its Jervois Base Metal Project in the Northern Territory.
The result comes from within a broader bornite-rich mineralised zone of 20.5% Cu and 302 g/t Ag over an estimated true width of 4.21m from 698.80m downhole.
“The new record copper assay from hole D6 at Rockface is extraordinary”
Addressing the update, KGL Resources Managing Director Simon Finnis said: “The new record copper assay from hole D6 at Rockface is extraordinary. Mineralogically, it represents 97% pure bornite and confirms the previous visual estimate. More importantly, together with previous results and the new visual mineral intersections announced here, they demonstrate that the high-grade shoot of massive sulphides has significant dimensions and grades that bode well for the future.
Equally exciting are the indications from the DHEM geophysics that the Rockface deposit remain open for significant extensions at depth.”
Consulting geophysicist Kate Hine of Mitre Geophysics further added: “DHEM has proved highly effective at defining Rockface mineralised zones. The DHEM results from KJCD481D3 and D4 both show a very strong in-hole response from the very high grade bornite plus chalcopyrite intersected in the holes, combined with an off-hole response from the distal part of the Rockface North lode.
The in-hole response is so strong that it mostly swamps the signal from the distant parts of the Rockface North lens. However, reviewing the results from KJCD481D3 and D4 in conjunction with the previous deep DHEM in this area indicate that the Rockface North is not closed off at depth, i.e., the DHEM does not indicate a ‘lower edge’ to the mineralisation. This confirms the potential for significant extensions to Rockface.”
The company notes that two additional holes have now been completed, with both intersecting new zones of massive sulphides, and assays pending. Six intercepts in total have now extended massive sulphides at the prospect to over 160m up and down plunge.
Moving forward, two drill rigs are continuing work at Rockface and the Reward prospect through until 2022 with a focus on extensional drilling to expand existing deposits. A feasibility study is planned for release early in the new year.
