Perth-based explorer Kairos Minerals (ASX: KAI) has reported further significant assay results from reverse circulation drilling at the wholly-owned Mt York gold project in the Pilbara region of Western Australia.
The latest results identified new high-grade lodes and thick shallow gold mineralisation in areas with minimal drilling.
A track-mounted rig was required to access complex locations, completing eight holes to depths of up to 310 metres to test extensions of the mineralisation down-dip.
Best new intercepts were 20m at 1.58 grams per tonne gold from 28m including 4m at 4.42g/t from 44m; 12m at 1.73g/t gold from 132m including 4m at 2.89g/t from 136m; 4m at 3.38g/t gold from 68m; and 4m at 2.51g/t gold from 96m.
Kairos executive chairman Terry Topping said the new results continue to demonstrate the substantial upside and growth potential of the Mt York deposit.
Kairos also reported a thick zone of shallow mineralisation at the eastern end of the Breccia Hill pit which returned assays of up to 4.42g/t gold.
The results have increased the company’s confidence in the potential of Mt York to deliver high-grade ore during the first years of mining.
Kairos has now completed its major drill program for the 2021 field season with a total of 95 holes completed for 14,988m.
Assays are pending for 28 holes, with several 1m samples already awaiting analysis at the laboratory.
In June, Kairos defined a conceptual exploration target of between 4.4-7.4 million tonnes at a grade of up to 1.8g/t gold for areas in close proximity to the Mt York and Iron Stirrup deposits and the Zakanaka prospect within the Mt York project.
The target was in addition to the project’s current mineral resource of 20.9Mt at 1.3g/t gold for 873,500 ounces of contained gold, and excluded untested greenfields potential and extensions of the nearby Old Faithful deposit.
Results from the drilling program will feed into an updated mineral resource scheduled before year end.
