Lefroy Exploration (ASX: LEX) has reported ‘high-grade’ gold intersections from AC drilling at the Burns prospect, located beneath Lake Randall at its Lefroy Gold Project near Kalgoorlie.
The company reports that multiple drill holes at the prospect intersected gold mineralisation in the host Eastern Porphyry, up to 240m north of discovery hole LEFR260.
Key assays from the first 128 of 199 holes include:
- Hole LEFA1088:
- 16m @ 3.79g/t Au from 20m; including
- 8m @ 7.31g/t Au from 20m
- 16m @ 3.79g/t Au from 20m; including
- Hole LEFA1089:
- 24m @ 2.86g/t Au from 16m; including
- 16m @ 4.04g/t Au from 20m
- 24m @ 2.86g/t Au from 16m; including
Speaking on the results, Lefroy Exploration Managing Director Wade Johnson said: “These are two outstanding gold intersections from aircore drilling out beneath Lake Randall that further demonstrates the growing scale of the Burns copper gold system. We are fortunate to have the specialised lake rig on site elsewhere on Lake Randall and immediately mobilising back to Burns to scope out the footprint of this new mineralisation”

In October 2021 Lefroy commenced a staged drilling program to assess the broader limits of the Burns mineral system and surrounding geology. This program was tasked with evaluating multiple magnetic anomalies, ascertaining geological context of the wider prospect area, and expanding the geological framework to increase exploration search space.
2km north-west of Burns at the Lovejoy magnetic target, ‘encouraging’ assays were also returned, with results to date including:
- Hole LEFA1044: 4m @ 1.57g/t Au from 16m
- Hole LEFA1199: 8m @ 0.42g/t Au from 12m
- Hole LEFA1211: 11m @ 0.75g/t Au from 16m
The Lefroy Gold Project is comprised primarily of granted tenure, and covers over 637km² in the heart of the ‘world-class’ gold production area between Kalgoorlie and Norseman.

Moving forward, the company has re-prioritised its ongoing Lake Randall drill program and immediately mobilised its specialised lake drill rig to Burns in a bid to capitalise on the LEFA1088 and LEFA1089 results, with drilling about to commence.
Follow up AC, RC, and diamond drill work is also being planned to allow for further testing of the anomalies defined by the AC drilling and historical data.
