KGL intersects broad zone of mineralisation at Rockface

Australian mineral exploration company KGL Resources announced that its ongoing diamond drilling program discovered a broad zone of copper mineralisation at the Rockface prospect, located within its wholly-owned Jervois Copper-Silver Project in the Northern Territory.

According to the company, the current diamond drill hole KJCD197, which was designed to test Conductors 3 and 5, has intersected two significant zones of mineralisation within a broader downhole mineralised interval of 47.3m.

“Disseminated to semi-massive and massive chalcopyrite-pyrite has been observed in a moderately to intensively altered garnet-magnetite host rock from approximately 530.8m to 578.1m. This is approximately 70mdown dip of the two mineralised intercepts in KJCD195,” KGL told the ASX.

“Massive and semi-massive chalcopyrite-pyrite was observed from 535.4m to 543.5m, and is coincident with the position of Conductor 3. From 543.5m to 553.7m mineralisation consists of veined chalcopyrite-pyrite. From 553.7m to 556.0m, a zone of massive magnetite with trace disseminated chalcopyrite-pyrite sits between two main mineralised zones. Vein style chalcopyrite-pyrite is evident again from 556.0m to 561.8m, followed by another zone of semi-massive, massive and veined chalcopyrite-pyrite from 561.8 to 773.1m this second zone of intense mineralisation is coincident with the position of Conductor 5.”

Adertisement

KGL said the drill hole intersected Conductor 5 at -155mRL, approximately 30m below the top edge of the large anomaly that is modelled to extend to -330mEL, being over 700m below the outcropping Rockface mineralisation. According to the company, the modelled strike length if the two plates that comprise Conductor 5 is 260m.

“The style of mineralisation in KJCD197 is similar to that observed in KJCD195-6, KJCD171 and KJCD182-3. Chalcopyrite occurs as fracture fill within the magnetite host rock, and grades into zones of semi-massive and veined chalcopyrite-pyrite. The magnetite- chalcopyrite mineralisation is located at the sheared contact between a metamorphosed siltstone/mudstone sequence and a footwall meta-sandstone unit. This host rock is a moderately to intensely altered chlorite-garnet-magnetite assemblage,” reads the statement.

“The core for KJCD197 is currently being processed with the last of the samples dispatched to the laboratory early next week. Final assays are anticipated to be received by mid-September.”

The company also said that that high-grade copper mineralisation in the magnetite- chalcopyrite zone continues to respond very well to Down-Hole Electromagnetics (DHEM), adding that a survey of KJCD197 is planned for next week to assist in optimising the targeting of additional drilling into the highest grade mineralisation.
