Kairos Minerals Ltd (ASX:KAI) (“KAI” or the “Firm”) is happy to announce outcomes from the primary 16 diamond holes drilled at its Mt York Gold Challenge in WA’s Pilbara, the place present sources on the Major Pattern sit at 1.4Moz Au. The outcomes are from Gossan Hill (7 holes), Breccia Hill (5 holes) and Major Hill (4 holes) (Desk 1), and are proven on drill plan (Determine 1) and long-section (Determine 2).
Highlights
- 36 holes for 10,025m accomplished at Mt York, forward of schedule and on-budget; Stage 1 is an 80-hole, 18,000m useful resource enlargement program
- Outcomes for 16 holes acquired, with greatest intercepts together with:
- 21m @ 1.87 g/t Au from 169m incl 9m @ 3.19 g/t Au (25MYDD009);
- 5m @ 4.26 g/t Au from 299m (25MYDD010);
- 34m @ 0.81 g/t Au from 242m incl 7m @ 2.66 g/t Au from 269m (25MYDD012);
- 24m @ 1.17 g/t Au from 222m incl 7m @ 2.62 g/t Au from 222m (25MYDD016);
- 48m @ 1.03 g/t Au from 227m incl 11m @ 3.38 g/t Au from 264m (25MYDD017).
- Larger-grade mineralisation persistently reported throughout Major Pattern confirming and lengthening high-grade shoots in any respect prospects
- Encouraging first outcomes more likely to positively affect grades and widths of mineralisation for an up to date useful resource estimate later in 2025
- Drilling accelerated with third diamond drill rig able to low-angle drilling on website on the extremely potential however under-drilled Major Hill Prospect
Stage 1 drilling goals to spice up gold sources at Mt York and check extensions of high- grade shoots forward of a mineral useful resource estimate (MRE) replace anticipated in 2H CY25. Stage 2 drilling later within the yr or early 2026 goals to transform Inferred sources to larger confidence Indicated sources.
Kairos Managing Director Dr Peter Turner mentioned: “The primary outcomes from Mt York proceed to bolster our perception within the potential scale of this venture, and we’re on monitor to ship a brand new and far improved mineral useful resource estimate later in 2025 incorporating not less than 18,000m of further drilling outcomes. We proceed to ask ourselves ‘how huge is the Mt York gold useful resource’ and can enhance and broaden Stage 1 drilling if we consider the mineralisation continues to be open which seems to be the case for the time being.
We’re seeing good widths of mineralisation in areas the place the useful resource mannequin is unguided and importantly, stable higher-grade gold intercepts inside the lower-grade envelopes. From the earlier 2023 useful resource, Mt York has greater than 750,000 ounces of gold at 1.6 g/t Au and the present drilling is confirming that high-grade shoots are each horizontal inside the system, but additionally more likely to be in depth (>300m) along-strike in each footwall and hangingwall positions. That is nice information.
We’re drilling the western half of the big Major Hill Prospect the place the mineralised banded iron formation (BIF) host rocks attain 100m in true thickness however the place topographic challenges beforehand prevented drilling. With an appropriate small-footprint rig now in place, we will see an assemblage of sulphide-bearing BIF in lots of drill holes on this space that’s related to free-milling gold mineralisation in different elements of the Major Pattern.
With drilling scheduled to proceed into September and presumably past, we stay up for releasing outcomes as they grow to be accessible.
We’re assured Mt York will grow to be one of many Pilbara’s (and Western Australia’s) largest undeveloped gold sources with clear metallurgy as soon as drilling is full.”
Drill Outcomes
Outcomes from the primary 16 holes are proven in Desk 1. The Stage 1 drill holes have been designed to check the grades and widths of mineralisation and purposely in search of extensions of higher-grade pods inside the whole 3,000m-long Major Pattern Gold Deposit. The positions of the drill holes and their outcomes are proven on Determine 1 (plan view) & Determine 2 (long-section).
Holes 25MYDD007 to 25MYDD009 check gaps within the useful resource mannequin at Breccia Hill and make sure a number of zones of mineralisation, the place 25MYDD009 returned high-grade core of 9m @ 3.19 g/t Au from 176m. This confirms the extension of a high-grade pod of mineralisation some 75m away from historic drillhole KMYD040’s results of 10m @ 4.90 g/t Au from 257m1, that confirms that higher-grade mineralisation might properly kind vital, horizontal zones beforehand not recognised but confirmed in current structural interpretation.
Deeper drilling into the japanese facet of Major Hill has infilled and prolonged mineralisation with holes 25MYDD010, 012, 014 and 017. Large beneficial properties in each mineralisation width and grade are captured in gap 25MYDD017 that intercepted a number of zones together with 48m @ 1.03 g/t Au from 227m together with a higher-grade zone of 11m @ 3.38 g/t Au from 264m. This extends a brand new zone of high-grade mineralisation on the footwall place and kinds a part of the horizontal-plunging, high-grade zone drilled >300m to the west in gap 25MYDD012 (7m @ 2.66 g/t Au from 269m) extending to 25MYDD010 (5m @ 4.26 g/t Au from 299m) (see Determine 2). One other 5 drillholes are deliberate to the west of those holes to check the extension of the high-grade mineralisation for an extra 500m to the west (Determine 1).
The outcomes of the mineralised intercepts are thought of near true widths because the mineralisation has been intercepted orthogonally.
A 3rd diamond drill rig (DDH1 drill rig #83) able to low-angle drilling has been despatched to website to speed up this system, particularly on the poorly examined however potential Major Hill Prospect. Historic drill outcomes of 109m @ 2.09 g/t Au from 50m (MYD24A) completely in banded iron formation (BIF) host rocks reveal the significance of this prospect. The mineralised banded iron formation (BIF) rocks are the thickest (~100m true thickness) within the space however because of the topographic and entry challenges across the hill, the Major Hill goal has, till now, been inaccessible for drill rigs.
Holes 25MYDD001-006 are largely testing the mineralised banded iron formation (BIF) on the intense japanese finish of the Major Pattern at Gossan Hill.
Rig #83 is drilling the Major Hill Prospect extensively from each the northern and southern sides of the hill (see Photograph 2) to actually perceive the size of the useful resource on this space. There’s loads of proof that high-grade mineralisation exists at this prospect. Outcomes for these holes (25MYDD023, 028, 031, 032, 033, 034 – see Determine 1 and a pair of for location of holes) are awaited.
Additional drill outcomes are anticipated all through July, August and September and will likely be launched to the ASX as soon as routine quality-assurance, quality-control (QAQC) checks have been accomplished.
