Yandal Resources Ltd (ASX: YRL) has identified high-grade gold up to 14.4g/t Au in its final assay results from the Mt McClure RC drilling programme completed in the December Quarter 2022.
Mt McClure is located in the southern Yandal Greenstone Belt of Western Australia and includes approx. 60 sq. km of tenure 10km south-west from the historic Bronzewing mine and adjacent to the Orelia development both owned by Northern Star Resources.
The recent RC programme comprised 34 holes for 4,736m and was designed to test targets with the potential to add to the 136,000 Au Resource inventory at Mt McClure.
Holes were completed adjacent to the Success, Parmelia and Challenger Resource envelopes as well as at the emerging HMS Sulphur, Gilmore and Caroline Prospects.
The programme returned several highly encouraging intercepts, notably identifying high-grade mineralisation at depth beneath Gilmore, extending mineralisation down dip at Challenger and confirming strike continuity of the HMS Sulphur footwall zone.
The company is also progressing a 3D Leapfrog modelling exercise which is designed to identify potential high-grade plunging shoots within the broader mineralised zone, such as those described at the nearby +1Moz Orelia Deposit, which may warrant deeper drill testing.
This RC programme was the first drilling designed to test targets arising from the completion of the maiden Resource Estimates by Yandal at the Success, Parmelia and Challenger deposits in the September Quarter 2022,” Managing Director, Tim Kennedy, said.
“The programme was focussed on testing relatively shallow positions along strike and down-dip of the Resource envelopes and emerging prospects.
“We’re pleased to receive very encouraging intercepts at Challenger North and South, HMS Sulphur immediately north of Success and high-grade gold up to 14.4g/t Au on two intersections at Gilmore toward the southern end of our tenure.
“Importantly, the mineralisation at HMS Sulphur and Gilmore is shallow and does not form part of our current Resource inventory and further drilling is being planned to assess the potential of each.
As we move forward, we are undertaking a “Leapfrog” 3D modelling exercise before conducting deeper drilling. This will help us identify potential high-grade plunging shoots, similar to the nearby Orelia deposit, which is currently being mined by Northern Star.
“We know that these higher-grade shoots can have extensive down-plunge continuity, and targeting this possibility at our deposits will enable us to maximize our chances of success in deeper drilling.
“We’re also eagerly anticipating results from the current aircore programme at Mt McClure, which is testing high-priority targets including demagnetised zones associated with cross-structures and soil geochemical anomalism in the hanging wall sequence, to the east of the main Mt McClure mineralised trend.
“This programme holds great potential, and we are excited about the possibilities it presents for Yandal in the near future.
