Lefroy Exploration (ASX: LEX) has announced multiple ‘significant’ intervals of gold-copper mineralisation following a recently-completed RC drill program at the Burns Prospect within its Lefroy Gold Project in Western Australia.
The three-hole program, which was tasked with evaluating strike extensions from earlier drill hole LEFR260 at the prospect, has returned ‘significant’ mineralisation grades including:
- Hole LEFR320:
- 20m @ 0.76g/t Au, 0.87% Cu and 3.6g/t Ag from 94m incl.
- 9m @ 1.71g/t Au, 1.18% Cu and 3.78g/t Ag from 104m
- 64m @ 2.83g/t Au, 0.34% Cu and 1.25g/t Ag from 118m incl.
- 37m @ 4.23g/t Au, 0.44% Cu and 1.65g/t Ag
- 27m @ 0.82g/t Au, 0.07% Cu and 0.52g/t Ag from 185m
- 20m @ 0.76g/t Au, 0.87% Cu and 3.6g/t Ag from 94m incl.
- Hole LEFR321:
- 15m @ 1.17g/t Au from 100m
Speaking on the results, Lefroy Exploration Chairman Gordon Galt said: “The intersection in LEFR320 is outstanding by any measure and continues our excitement about the Burns area. LEX will follow up as soon as possible. We will look north, south, east and deeper around the current excellent intersections to establish the size of what we already have to JORC resource status as soon as possible.”

Lefroy reports that this recent data has reinforced an interpretation of a shallowly south plunging ‘high-grade’ mineralised zone with a broader Au-Cu-Ag-Mo system at Burns.
In addition, the company believes that the prospect is host to a large Au-Cu intrusion mineral system which is reported to be open at depth and along strike from hole LEFR260, and now the more recent LEFR320.
These results also corroborate previous AC drill results beneath Lake Randall that intersected multiple mineralisation intersections including 24m @ 2.86g/t Au from 16m, further supporting a northerly trending ‘high grade’ zone.

The Project is split into Eastern Lefroy, where LEX manages early exploration, and Western Lefroy, where renowned gold producer Gold Fields (JSE: GFI) are managing exploration via a farm-in agreement.
With RC drilling at Burns now complete, the company reports that it will move forward with over 1,000m of co-funded EIS diamond and RC drilling to support a maiden Mineral Resource Estimate.
The company awaits multi-element assays for holes LEFR321 & LEFR323.
