Kairos Minerals Ltd (ASX: KAI) has received strong results from nine drill holes at the 100%-owned Mt York Gold Project in the Pilbara Region of Western Australia.
Kairos completed 46 drill holes for 11,013.6m of drilling, including 5,945.6m of diamond core drilling, between September and December 2022 with the aim of
1) drilling beyond the current resource model, especially at depth to increase resources and
2) infill drilling within the resources to increase confidence in the resource category along the contiguous Main Trend (Main Hill – The Gap – Breccia Hill – Gossan Hill).
Results for 33 of the 46 holes were reported earlier in February, with results of a further nine holes reported here. Results for the remaining four holes are pending and expected in March.
These are outstanding intersections which extend the known mineralisation directly below the existing 1.1Moz resource,” Managing Director, Dr Peter Turner, said.
“Importantly, the results support our belief that wide, high-grade shoots can now be mapped out and targeted at depth over the entire 3km length of the Main Trend.
“The exceptional result of 10m @ 4.9 g/t Au from 257m from drillhole KMYD040 at Breccia Hill not only demonstrates the potential for open pit resource extensions well beyond the current resources and optimal pit shell, but also highlights the potential for future underground mining scenarios.”
Drillholes KMYD020, KMYD040 and KMYD051 represent some of the deepest drilling at Main Hill, Breccia Hill and Gossan Hill completed to date and show the open nature of mineralisation at depth below the current resource.
New results from the drilling include 10m @ 4.90 g/t Au from 257m including 7m @ 6.02 g/t Au from 257m in hole KMYD040. This result at Breccia Hill sits approximately 85m below the current resource and and has the potential to increase open pit resources at depth, as well as demonstrating the potential for further exceptional widths and grades ameniable to underground mining, with mineralisation remaining completely open at depth.
Results from KMYD020 at Main Hill include 12m @ 0.83 g/t Au from 131m, 25m @ 0.47g/t Au from 156m, 19m @ 0.51 g/t Au from 197m, and 21m @ 1.38 g/t Au from 214m including 6m @ 2.80 g/t Au from 225m. These results confirm and demonstrate the significant widths of mineralisation and multiple stacked lodes that characterise the Main Hill deposit
The current mineral resource estimate for the project stands at 28.01 Mt @ 1.23 g/t Au for 1,104,000 Mozs Au2 including 13.93 Mt @ 1.3 g/t Au for 581,000 ounces (Indicated) and 14.08 Mt @ 1.15 g/t Au for 523,000 ounces (Inferred). The Kairos team are confident that these new results, coupled with bulk density measurements of selected core samples that are currently at Intertek for specific gravity tests, will support a significant increase in the mineral resource.
Mineralisation at Main Hill, The Gap and Breccia Hill dip steeply to the SW, SSW and S respectively and forms an arcuate trend towards the east at Gossan Hill.
Main Hill mineralisation currently remains relatively undrilled due to challenges for drill-rig access. Hole KMYD071 was drilled into Main Hill and a 15.4m hanging-wall zone of high-sulphides was reported – results are pending, expected in March 2023.
