Lefroy Exploration Limited - Burns drilling targets near surface high grade gold potential

About this update from Lefroy Exploration Ltd.

Lefroy Exploration Limited ('Lefroy' or 'the Company') (ASX: LEX) is pleased to report on exploration activities at Burns. The Burns Gold Deposit contains an MRE of 42.96 Mt @ 0.36 g/t Au for 497,472 ounces (Indicated 32.31 Mt @ 0.38 g/t Au for 394,308 oz. Inferred 10.65 Mt @ 0.30 g/t Au for 103,165 oz). Inclusive within this resource is Burns High-Grade which contains 4.22 Mt @ 1.18 g/t Au for 159,285 ounces (Indicated 4.11 Mt @ 1.19 g/t Au for 157,215 oz. Inferred 0.1 Mt @ 0.63 g/t Au for 2,070 oz). LEFROY CEO, GRAEME GRIBBIN , COMMENTED: 'Since we reported back in October 2024 about the high-grade potential of the Burns Central mineral resource, the Company has transformed its exploration and resource growth strategy, focusing on unlocking value from the near-surface high-grade oxide portion of the Burns resource' 'With this renewed focus, I am excited that the Company is returning to Burns, with the sole focus of growing the high-grade resource, advancing the full exploration potential of the district and realising value for Lefroy shareholders'. Burns Background The Burns Deposit lies within the broader Lefroy Gold Project located 70km southeast of Kalgoorlie, proximal to the St Ives gold camp (Gold Fields Ltd JSE: GFI) and the Daisy Milano and Mt Monger gold operations (Vault Minerals Ltd ASX: VAU). In October 2024 (refer ASX release 03 October 2024 ) the Company reported that a significant, structurally controlled high-grade gold zone had been reported within the existing Burns Central Mineral Resource Estimate (MRE), including 4.22Mt @ 1.18 g/t Au for 159,285 contained ounces, reported within 200m of surface. Additionally, in September (refer ASX release 9 September 2025 ), the Company announced that it was set to commence a focused drilling program at Burns, designed to: Metallurgical Diamond Drilling Program to commence at Burns Planning has now been completed for a single diamond hole, targeting the high-grade core of the Burns Central system. Metallurgical test work to be performed on this drill core is designed to confirm the preliminary metallurgical results completed in 2023 and guide further studies on potential development pathways at Burns. This drill program will consist of a single diamond hole (HQ size), drilled to a depth of between 200 - 250m targeting the high-grade core of Burns. Drilling is set to commence within 2 weeks, for completion by mid-November. Building on the very encouraging preliminary test work completed by the Company in 2023, diamond drill core material from this new drilling program (vs RC rock chip samples supporting the 2023 test work) will provide a more geologically intact sample, allowing for more definitive gold recovery results to be obtained. Subsequently, this test work will allow for a more complete measure of both expected gold gravity recovery rates and cyanide leachable gold under standard CIL leach conditions. As previously reported (refer ASX release 9 September 2025 ), the Company completed preliminary metallurgical test work on the Burns Deposit in late 2023, submitting 6 reverse circulation (RC) composite samples representing the high-grade zone of Burns. Test work confirmed significant gravity recoverable gold averaging 41%. Total leach recoveries averaged approximately 97% (refer ASX release 3 October 2024 ) providing confidence that the samples tested are free-milling and amenable to recovery through conventional CIL processing circuits.
