Drilling Continues to Define Larger Scale to Burns Au Cu System

Lefroy Exploration Limited (ASX: LEX) (“Lefroy” or “the Company”) is pleased to provide a progress report for the two-hole diamond drill program underway at the Burns Au-Cu intrusion-related mineral system. Burns is within the Company’s wholly owned Eastern Lefroy Gold Project, located 70km southeast of Kalgoorlie. The first hole, LEFD006, has been completed to a downhole depth of 1245.8m, with the second hole, LEFD007a, located 240m to the south now underway.

• The EIS co-funded diamond drill hole, LEFD006, has been completed to a downhole depth of 1245.8m. This is the deepest hole completed at Burns to date.
• LEFD006 intersected a suite of diorite-porphyry units over a broad 195m downhole interval, from 710m to 905m. These units are broadly grouped as the Central Porphyry, and has established that the vertical continuity of the intrusive system previously found by shallower drilling extends to 1000m from surface and that it remains open for further extension along strike and at depth
• In addition, the hole has established four key geological domains, including the Central Porphyry suite, which when combined define a 600m width to the intrusive system and provide further evidence that Burns is a large-scale mineral system.
• Each of the four geological domains has a different alteration and mineralisation assemblage, which evidences that Burns is a multi-stage mineral and porphyry system.
• Core samples from LEFD006 have been submitted in batches to the laboratory, with first results expected in September
• The second diamond drill hole, LEFD007a, is at 231m downhole, with a planned 500m hole depth. LEFD007a is 240m south of LEFD006 and has intersected multiple intervals containing native copper within the altered Western Basalt (see below).

Burns is a new and unique style of an intrusion-related, gold (Au)-copper (Cu)-molybdenum (Mo)-silver (Ag) mineral system, hosted by Archean age rocks in the Eastern Goldfields Province (EGP) of Western Australia. LEX is aiming to advance the understanding of the scale and genesis of the system through this deep drilling program.

The gold, copper, silver (and lesser molybdenum) mineralisation, hosted by multiple, diorite-porphyry intrusives and high-magnesium basalt, are considered by the Company to be a new and unique style of gold-copper mineralisation near Kalgoorlie, located within a land holding dominated by LEX.
