Kairos Minerals Limited announced Mt York Gold resource increase 26% to 1.1Moz. The current resource estimate was completed by Christopher Speedy of Encompass Mining Consultants using wireframes built by Kairos's technical team and based on a 0.3 g/t Au envelope of mineralisation. The resource includes an additional 14,988m of drilling at all prospects in late 2021 by the company.

The resource includes the continuous and contiguous deposits of Main Hill, The Gap, Breccia Hill and Gossan Hill that form an arcuate form with mineralisation dipping moderately to steeply to the south to south-west. Mineral Resource Estimate for the Mt York Gold Project using a 0.7 g/t lower cutoff. The deposits of Main Hill, The Gap, Breccia Hill and Gossan Hill are contiguous orebodies with Iron Stirrup and Old Faithful being satellite deposits 4.5km and 6.5km to the north respectively.

Grade-tonnage table using different lower grade resource cutoffs for all gold deposits at Mt York. The reported resource estimations for 0.5 and 0.7 g/t Au lower cutoffs are discussed in the release. The resource estimation method applied was ordinary kriging that is considered a robust method for grade interpolation where geological and mineralisation control is well constrained.

The resource estimate by resource category and constrained by a 0.7 g/t Au cutoff grade. For a 0.5 g/t lower cutoff grade, the resource estimate increases 52% to 1.33 Mozs (39.82 MT @ 1.04 g/t Au for 1.329,000 ounces). Detailed resource investigations looking at the lower cutoff gradeswill be investigated during the pre-feasibility study when all mining & processing costs are reviewed.

The resource wireframes were extended to a consistent -135mRL (average surface level is +175mRL) from Main Hill, The Gap and Breccia Hill. This equates to a vertical wireframe depth of 310m below surface. However, the resource extends to only a maximum depth 200-225m below the average surface level and importantly, the drilling only extends to an average depth of about 150m below the surface along the entire resource area.

The pit shell developed on a $2,500 gold price bottoms-out on the drilling meaning that there is scope to significantly increase the resource down- dip if the mineralisation is intercepted below the current pit shell. This extensional drilling below the current pit shell is a clear and obvious target and is the subject of the new 20,000m of drilling along the entire 2,800m strike length of the Main Trend resource. The Kairos Technical Team firmly believe that extending the resource significantly below the current level is extremely realistic and achievable.

At Gossan Hill (and the eastern end of Breccia Hill), the maximum wireframe depths range from - 40mRL in the west to +125mRL in the east with an average surface RL of approximately +190mRL giving a vertical wireframe depth range of 230m and 65m respectively. Drilling is limited to a maximum vertical depth of approximately 100m below surface and many holes are planned beneath the optimal pit shell base in this area.
