Wide Gold Intercepts at Mt York Support Future Resource Growth

Kairos Minerals Ltd (ASX:KAI) (“KAI” or the “Company”) is pleased to announce results from the first 16 diamond holes drilled at its Mt York Gold Project in WA’s Pilbara, where current resources at the Main Trend sit at 1.4Moz Au. The results are from Gossan Hill (7 holes), Breccia Hill (5 holes) and Main Hill (4 holes) (Table 1), and are shown on drill plan (Figure 1) and long-section (Figure 2).

Highlights

• 36 holes for 10,025m completed at Mt York, ahead of schedule and on-budget; Stage 1 is an 80-hole, 18,000m resource expansion program
• Results for 16 holes received, with best intercepts including:
  • 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).
• Higher-grade mineralisation consistently reported across Main Trend confirming and extending high-grade shoots at all prospects
• Encouraging first results likely to positively impact grades and widths of mineralisation for an updated resource estimate later in 2025
• Drilling accelerated with third diamond drill rig capable of low-angle drilling on site at the highly prospective but under-drilled Main Hill Prospect

Stage 1 drilling aims to boost gold resources at Mt York and test extensions of high- grade shoots ahead of a mineral resource estimate (MRE) update expected in 2H CY25. Stage 2 drilling later in the year or early 2026 aims to convert Inferred resources to higher confidence Indicated resources.

Kairos Managing Director Dr Peter Turner said: “The first results from Mt York continue to reinforce our belief in the potential scale of this project, and we are on track to deliver a new and much improved mineral resource estimate later in 2025 incorporating at least 18,000m of additional drilling results. We continue to ask ourselves ‘how big is the Mt York gold resource’ and will increase and expand Stage 1 drilling if we believe the mineralisation continues to be open which appears to be the case at the moment.

We are seeing good widths of mineralisation in areas where the resource model is unguided and importantly, solid higher-grade gold intercepts within the lower-grade envelopes. From the previous 2023 resource, Mt York has more than 750,000 ounces of gold at 1.6 g/t Au and the current drilling is confirming that high-grade shoots are both horizontal within the system, but also likely to be extensive (300m) along-strike in both footwall and hangingwall positions. This is great news.

We are drilling the western half of the large Main Hill Prospect where the mineralised banded iron formation (BIF) host rocks attain 100m in true thickness but where topographic challenges previously prevented drilling. With a suitable small-footprint rig now in place, we can see an assemblage of sulphide-bearing BIF in many drill holes in…
