Kairos Minerals Ltd (ASX: KAI) has reported strong results of 33 drill holes at the 100%-owned Mt York Project in the Pilbara Region of Western Australia.
Kairos completed 46 drill holes for 11,013.6m of 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).
Diamond core drilling accounted for 5,945.6m or 54% of the total drilling programme and has assisted in the collection of valuable data for geological modelling and to determine bulk densities for the next round of resource estimation.
Three additional holes were drilled but not sampled – two holes were drilled as pre-collars awaiting diamond tails and one diamond hole at Main Hill (KMYD070) was abandoned due to bad ground. Results for 33 of the 46 holes are reported here, results for the remaining 13 holes are pending and expected in February and March.
The current mineral resource estimate for the project stands at 28.01Mt @1.23 g/t Au for 1,104,000 Mozs Au1 including 13.93Mt @1.3 g/t Au for 581,000oz (Indicated) and 14.08Mt @1.15 g/t Au for 523,000oz (Inferred).
The Kairos team are confident that these new results, coupled with bulk density measurements of selected core samples, will support a significant increase in the mineral resource.
The current results demonstrate consistent and wide zones of mineralization, often with intervals of higher-grade gold mineralization above the current global resource grade of 1.23g/t Au within lower grade zones. This drilling has
1) tested extensions of mineralization beneath historic drilling for new potential additions to mineral resources and
2) has tested areas with low-confidence resources (unclassified or inferred categories) to increase the amount of high-confidence resources (measured and indicated) in preparation for reserve estimation.
The results are from some of the deepest drilling along the Mt York Main Trend, especially along the eastern half of the deposit (Breccia and Gossan Hills) where historic drilling was relatively shallow (<150m deep).
Mineralization 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.
Interestingly, the new drilling at depth at Gossan Hill confirms that the mineralization shallows from an otherwise steep south dip closer to surface.
Main Hill mineralization currently remains relatively undrilled due to challenges for drill-rig access. Hole KMYD071 was drilled into Main Hill and a 15.4m hangingwall zone of high-sulphides was reported – results are pending, expected in March 2023.
“The latest drilling has been highly successful, intersecting high-grade mineralization over significant widths below the current 1.1Moz Resource,” Managing Director, Dr Peter Turner, said.
“The results support our view that Mt York is a big system in a Tier-1 location with consistent mineralization.
“More assays are pending and we are confident that the resource will continue to grow.
“In parallel with our strategy to increase the inventory, we are progressing preparations for project development with Mining Lease Applications already submitted”.
