Inca Minerals Jean Elson Project

Inca Minerals reports high-grade gold-copper mineralisation at Jean Elson

Inca Minerals Limited (ASX: ICG) has announced that a rock chip sampling program at the Ningaloo Prospect, Camel Creek, part of the recently-granted Jean Elson Project in the Northern Territory has confirmed significant gold-copper mineralisation, heightening the IOCG potential of Jean Elson.

Peak assays included 3.21g/t Au + 1.89% Cu and 0.36g/t Au + 1.42% Cu. The company said that the rock chip sampling resulted in the discovery of new mineralised veins and the extension of previously-known quartz-haematite veins.

ICG said that copper-dominant mineralisation is now observed over a 1.25km-wide zone that remains open in all directions. The company said that a project-wide 30,000 line kilometre Airborne Magnetic-Radiometric (AMAGRAD) survey has been scheduled for September.

The company also announced an important update from Riqueza regarding the commencement of the NE Area drilling program, and success in its Co-funding grants for exploration in the Northern Territory.

Rock chip sampling program at Jean Elson

The company had collected 45 rock chip samples during a recent mapping and sampling program that targeted the two main prospect areas within the Jean Elson Project – the Mt Cornish South and Camel Creek prospects. Seven rock chip samples were collected from Mt Cornish South and 38 from the general area of Camel Creek.

ICG reported that high-grade gold and copper results were returned from the assay results from recent rock chip sampling.

High-grade Au-Cu mineralisation

Inca Minerals reported that the assay results returned the first signficant gold mineralisation delivered from the Jean Elson Project to date, in addition to strong copper (Cu) and elevated silver (Ag) and bismuth (Bi).

ICG said that sample JE0097 returned 3.21g/t Au + 1.89% Cu + 0.28% Bi, with the nearby JE0094 also returning an encouraging result of 0.36g/t Au + 1.42% Cu + 957ppm Bi.

Rock chip sample location and important assay results are as shown below.

New mineralised veins, extension of veins

The company said that these samples, together with assays from JE0096 (1.28% Cu), form the newly discovered extension of the V2 vein and lie 25-40m NE of the previously-reported KV vein.

ICG noted that mineralisation at V2 comprises three sub-cropping quartz-iron (Qtz-Fe) veins over a 16m-wide zone, with Cu enrichment noted to extend beyond the veins and into the altered granite host rock.

Highlights included JE0107 (float sample) with 9.65% Cu within a 70m-wide zone of intermittent brecciation and alteration of the host granite that includes 0.19% Cu (JE0105; in situ) and 0.16% Cu (JE0108; in situ); JE0096 (in situ) with 1.28% Cu in quartz-haematite veined granite with abundant disseminated malachite; and JE0098 (in situ) with 1.27% Cu in quartz-haematite veined granite with disseminated malachite-chalcopyrite weathering to haematite and extending the J-Vein 75m along strike (now >150m long).

Inca Minerals said that the in-situ Cu enriched structures are now known to occur over a 1.25km wide zone.

Inca announced that it has scheduled a 30,000 line km AMAGRAD survey to commence in September

AMAGRAD survey planned

Inca announced that it has scheduled a 30,000 line km AMAGRAD survey to commence in September. Results of this survey will be used to refine targets to determine requirements for follow up exploration. The company noted that given the widespread but thin sand cover lying over much of the Project area, it is considered likely that future exploration may identify additional areas of interest.

Other updates

The company reported that it was successful in its two application of government co-funding in the Northern Territory. Co-funding was awarded for the Company’s Frewena Group AMAGRAD survey and for Jean Elson’s AMAGRAD survey.

The company said that at Riqueza, the delays in the permitting regime due broadly to persistent logistical problems associated with COVID-19 travel and work restrictions were overcome to allow the Company to commence drilling.
