Lefroy’s ‘first of a kind’ alkalic gold-copper porphyry discovery at Burns is just the tip of the iceberg

The interpretation of recent drill results at the Burns gold-copper project reinforces LEX’s view that there is significant scale to its ‘first of a kind’ discovery.
In early March results from 67 reverse circulation drill holes confirmed a unique alkalic-porphyry style mineral system with a strike length of at least 500m, enriched with gold-copper-molybdenum-silver and cobalt.
Lefroy Exploration (ASX:LEX) says these results, coupled with previous results from 11 holes drilled at prospects along strike within the 2.5km Burns Corridor, suggest an extensive mineral system with considerable potential for significant resource expansion.
In the short time since Burns’ first discovery hole in 2021, wide scale exploration in the form of research and data compilation and interpretation has consolidated the company’s understanding of the main Burns Central body as being an Archaean alkalic-porphyry-style mineral system of considerable scale that is completely unique to the Eastern Goldfields, and even Western Australia.
“Exploration at Burns is still in its early days but mineralisation at Burns Central remains open in all directions,” LEX managing director Wade Johnson says.
“We have only focused on the shallow part of the system at Burns Central, where we are progressing a maiden mineral resource estimate on track for delivery in April.
“Compilation of our new Burns long-section reinforces that Burns Central is just the tip of the iceberg in context of the greater Burns Project area’s total endowment.”
Directly along strike of Burns Central are multiple anomalies in the 2.5km long Burns Corridor, where early drilling data has signalled a high probability of further gold and copper discoveries with direct linkage to mineralisation at Burns Central.
“The quality of intercepts among the limited holes Lefroy has drilled at prospects along the Burns Corridor is nothing short of exceptional and provides significant exploration upside at the Burns project,” Johnson explains.
Within the greater Burns Project area, Lefroy has completed nine first-pass RC holes within the Burns Corridor, along the shoreline of Lake Randall.
These anomalies occur within a 2.5km trend and display a similar signature to Burns Central, which remain effectively untested and limited only by a lack of drill data.
Prospects identified along the trend which will be subject to further drilling activity include Smithers, Flanders, Skinner, Millhouse, and Ralph.
Lovejoy, around 1.3km north of Burns Central, will be another area of focus where two diamond holes last year returned broad intervals of gold and copper and discrete higher-grade zones in a hydrothermal breccia.
