Lefroy Exploration Limited reported further and final assay results for the 67-hole RC resource drill program completed at Burns Central in the December 2022 Quarter. Burns is within the Company's wholly owned Eastern Lefroy Gold Project located 70km southeast of Kalgoorlie, Western Australia. In October 2022, the Company commenced an RC resource drill program to evaluate the Burns Central system to a vertical depth of 200 metres from surface and within an approximate area of 700 metre north-south by 450 metre east-west.

Details of the program and results from the first 28 RC holes were reported to the ASX on 6 February 2023. The data from this 67-hole program, in combination with previous drilling data, will support a Mineral Resource Estimate (MRE) for Burns Central. The MRE is now scheduled to be finalised in early April 2023 due to a delay in receiving final assay results.

Table 1 shows the latest gold and multi-element results from the final 39 RC holes, which are all located on six consecutive 40m spaced drill sections (Figure 1) north of the baseline (0N or discovery drill section). The program was designed to evaluate copper-gold mineralisation in the Western Basalt and Central Porphyry by infilling and expanding on earlier RC and diamond holes drilled by the Company. Multiple, shallow, thick intervals of gold and copper mineralisation have been intersected as noted in the highlights section of this release.

These results significantly strengthen and expand the mineralised footprint of Burns Central and, taken together with the previous results, outline a large zone of gold, copper and silver mineralisation, with a strike of at least 480m and vertical depth of approximately 200m from surface, which remains open. Mineralisation in the RC holes (Table 1) north of the baseline section follows two distinct trends: A higher-grade gold trend predominantly hosted by diorite porphyry within the `Central Porphyry' domain, is associated with an interpreted north-south structure. This gold trend is open at depth and to the north beneath Lake Randall, where it has only been partially tested by shallow aircore drilling.

A north-west trend of gold and copper is hosted largely in basalt surrounding the porphyry intrusions, with its limits yet to be defined. Importantly, the mineralised northwest trend of gold and copper is interpreted to coincide with a number of magnetic anomalies over a 2.5km strike length (Figures 1 and 5), which the Company refers to as the `Burns Corridor'. The Company considers these magnetic anomalies to be part of a larger scale group of alkalic-porphyry-style systems, centred around the Burns intrusive complex.

Alkalic porphyry gold-copper systems have the potential to form large tonnage mineral deposits where multiple porphyry systems occur proximal to each other, such as Cadia Valley in New South Wales and in British Columbia, Canada. Exploration by the Company to date has been focused at Burns Central, where mineralisation remains open along strike and at depth. The `Smithers' magnetic anomaly occurs immediately north of Burns Central and has only been effectively tested by a single RC drill hole (LEFR294) from a drill program in 2021.

This hole intersected broad gold, copper, and silver mineralisation, including 62m @ 0.22g/t Au, 0.13% Cu, and 0.16g/t Ag from 84m in LEFR294. This anomaly is a high priority target to expand mineralisation immediately beyond Burns Central. In addition, the Company will focus drilling at the other magnetic anomalies within the Burns Corridor, where initial broad-spaced drill testing has provided confidence that the Burns Project will evolve into a large mineral system.

This includes `Lovejoy,' located 1.5km north of Burns, where multiple, thick, downhole intervals of gold and copper were intersected in 2022 and include a combined 96m of Cu-Au mineralisation in hole LEFD009 comprising 11m @ 0.68% Cu and 0.40g/t Au from 50m, 40m @ 0.20% Cu from 208m and 45m @0.33% Cu and 0.30g/t Au from 258m.
