Killi Resources Limited announced the drill results from the diamond drill hole completed at the West Tanami Project, Kimberley region of Western Australia. Magmatic copper mineralisation in the form of the mineral chalcopyrite was observed in drill core during the program, with assays now confirmed with the zone of massive sulphides returning 4.2m at 728ppm Cu, 58ppm Co and 0.46g/t Ag including 0.6m at 2,730ppm Cu, 114.5ppm Co, & 1.23g/t Ag. Geological logging identified a mafic unit from 818m to 888m (~70m width) with grainsize decreasing with depth.

Within the mafic unit a 10m zone (834.1m ­ 844.6m) of significantly increased sulphides (pyrrhotite & chalcopyrite) grading from disseminated-semi-massive sulphides down hole. Laboratory assays have been received and confirm within the 10m zone copper, cobalt and silver anomalism. The assays returned 4.2m at 728ppm Cu, 58ppm Co and 0.46g/t Ag from 839m, including 0.6m at 2,730ppm Cu, 114.5ppm Co, & 1.23g/t Ag from 840.8m, with cobalt and silver often associated with magmatic systems. Multiple mafic units were logged downhole from 25-74m (49m), 306-364m (28m), 746-770m (24m) and 818-888m (70m), suggesting there is a significant opportunity to explore the magmatic potential.

Little is known about the mafics of the Tanami region, with this intercept being the first confirmed result of magmatic copper mineralisation in the district. The diamond hole was completed with the Geological Survey of Western Australia (GSWA) as part of the Exploration Incentive Scheme (EIS), where the Company received a 50% refund on drilling costs associated with TMDD0001. The drill hole was competed to a total depth of 890.4m, on a shallow angle to transect and define the stratigraphy of the prospect.

Lithology, structural and geochemical data has determined the prospect to be within the Dead Bullock Formation of the Tanami stratigraphy. This formation, highly prospective for orogenic gold, and now with this result, highlights an opportunity for magmatic sulphide mineralisation. Nickel and nickel-copper deposits can be one of two styles of mineralisation, either magmatic or lateritic.

Magmatic sulphide systems form from magmas or molten rock that comes from the earth's mantle and intrude into the earth's crust. These magmas are a source for fluids, metal and energy and follow pathways of least resistance to the crust, forming volcanic deposits near surface. Australia is host to 26.8% of the worlds nickel resources and the dominant form of mineralisation is magmatic hosted sulphide deposits.

Magmatic sulphide deposits in Western Australia commonly host nickel or nickel-copper and are found within the Archaean greenstone sequences and laterites of the Eastern Goldfields. Recent magmatic sulphide discoveries within the state are located within Proterozoic terrains with deposits in the Albany-Fraser Orogen (Nova-Bollinger, Ni-Cu-Co, Independence Group), Musgrave Province (Nebo-Babel, Ni-Cu, OZ Minerals) and the Kimberley Craton (Savannah, Ni-Cu-Co, Panoramic Resources). Rocks from the West Tanami Project were formed during the same period (Proterozoic) and are prospective for the same minerals.

Future exploration: Based on the current understanding and research completed the Company believes a geophysical electromagnetic and/or gravity survey will be the most useful exploration method to generate potential sulphide targets, to be drill tested in the coming field season. The samples which returned anomalous Cu-Co-Ag will also be analysed for platinum and palladium to further add to the picture of the mafics. The Company is also planning exploration programs to test the gold and rare earth targets generated from the soil and aircore programs at the project in 2022.
