Lefroy Exploration (ASX:LEX) advances resource extension drilling at Burns Gold Deposit

Lefroy Exploration has commenced a new phase of Reverse Circulation drilling at the Burns Gold Deposit within its broader Lefroy Gold Project in the Kambalda–Kalgoorlie district, marking a targeted effort to test the continuity of the high-grade corridor that has become the principal focus of recent exploration.

The program follows the completion of metallurgical diamond drilling and aims to expand shallow resource potential as the company progresses multiple fronts across its gold development portfolio.

HIGHLIGHTS

• RC drilling underway at Burns targeting the high-grade gold corridor to the north.
• Shallow extensions tested along strike of earlier high-grade intersections including 38m @ 3.87 g/t Au from 26m, 30m @ 2.43 g/t Au from 27m and 7m @ 3.97 g/t Au from 37m.
• Metallurgical diamond drilling completed with assay and metallurgical results expected in January 2026.
• Burns Central hosts an MRE of 42.96Mt @ 0.36 g/t Au for 497,472oz, including a high-grade component of 4.22Mt @ 1.18 g/t Au for 159,285oz.

The Burns Gold Deposit forms part of Lefroy’s 635km² Lefroy Gold Project southeast of Kalgoorlie, within a region defined by major operations such as St Ives, Daisy Milano and Mt Monger.

The current RC program consists of up to 10 drill holes for approximately 1500m across three drill lines designed to evaluate the northern extension potential of the high-grade zone that the company reported in October 2024.

Earlier drilling on this northern flank delivered robust intervals including 38m @ 3.87 g/t Au from 26m, 30m @ 2.43 g/t Au from 27m and 7m @ 3.97 g/t Au from 37m, collectively highlighting substantial near-surface mineralisation within 200m of depth.

The recently completed metallurgical diamond drill hole was positioned through the high-grade corridor to obtain core for test work that will extend the preliminary metallurgical results generated in 2023.

Those initial studies demonstrated encouraging gold recovery characteristics, with gravity recoverable gold averaging 41% and total leach recoveries averaging approximately 97%, indicating that the tested material was free-milling and compatible with conventional CIL processing.

Lefroy Exploration Chief Executive Officer Graeme Gribbin commented,

“We are very excited to end the year targeting the resource growth potential of the high-grade gold corridor at Burns Central. With the gold system open both to the south and north, we are enthusiastic in our endeavours towards targeting and unlocking the full resource potential at Burns.”

This phase of drilling integrates with Lefroy’s broader strategy, which includes advancing the Lucky Strike Gold Deposit through a profit share mining agreement.

Lucky Strike, containing 79,600oz, commenced mining in December 2025, marking an important milestone in the company’s transition toward generating cash flow while continuing to grow its resource base.

The alignment of exploration activities, metallurgical assessment and staged production planning supports a cohesive operational framework across Lefroy’s near-surface deposits, including Mt Martin and Burns Central.

With drilling scheduled for completion in December and assays due before the end of January 2026, Lefroy is approaching a significant information phase that will shape the understanding of the Burns high-grade system and its potential scale.

The integration of new metallurgical data will further refine assumptions for future study work.

Located within one of Australia’s most established gold belts and supported by more than 1Moz in total resources across its portfolio, the company enters 2026 with several catalysts linking exploration outcomes with development momentum.
