Lefroy’s Burns copper-gold prospect continues to bulk up
Link copied to
Lefroy’s exciting Burns prospect continues to scale up with recent high-grade gold intersections demonstrating the expanding continuity of the Eastern Porphyry.
Assays received for 128 holes of the maiden 199 hole aircore drill program to evaluate the eastern extension of the Burns copper-gold corridor returned multiple gold intersections up to 240m north of the LEFR260 discovery hole.
Notable results include – 8m grading 7.31 grams per. tonne (g/t) gold from 20m within a broader 16m zone at 3.79g/t gold from 20m (LEFA1088) and 16m at 4.04g/t gold from 20m within 24m at 2.86g/t gold from 16m (LEFA1089).
“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,” managing director Wade Johnson said.
“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
Lefroy Exploration (ASX:LEX) says the numbers continue to enhance a growing copper-gold intrusion related mineral system over a 2000m corridor, which remains open, and provides further support for its targeting methodology.
Highlighting just how strong the potential of the Burns prospect is, LEX has re-prioritised its ongoing Lake Randall drill program and immediately mobilised the specialised lake drill rig to Burns to expand on the LEFA 1088 and 1089 results
And if that wasn’t enough, initial wide-spaced evaluation of the Lovejoy magnetic target about 2,000m northwest of Burns has also intersected similar diorite porphyry with notable results such as 4m at 1.57g/t gold from 16m and 11m at 0.75g/t gold from 16m.
Assays are pending for a further four drill traverses to the north of the high-grade intersections over an additional 400m of the Eastern Porphyry as well as an additional 301 aircore holes drilled in Lake Randall since December 2021.
The success of the Burns drilling to date is a sure sign the company’s interpretation that magnetic anomalies defined in August represent magnetite alteration zones within and surrounding porphyry dioritic intrusions are additional, and similar in style, to Burns is right on the money.
Lefroy’s most recent results have been particularly encouraging with LEFA1089 also ending in copper-gold mineralisation – 8m at 1.91g/t gold and 0.31% copper from 32m to end of hole.
This, along with results from other holes immediately northeast of the discovery section, demonstrate Burns’ expanding footprint.
Detailed compilation of the geology and geochemical footprint of the Burns system will be undertaken pending the results from the remaining 71 AC holes.
Further drilling using the specialised lake drill rig will close the drill spacing to the north and south of the LEFA1088-1089 drill section focussing on the Eastern Porphyry to a 40m-by-40m drill spacing.
Planning is also underway for a program of wide spaced RC drilling to evaluate the dimensions of the palaeochannel mineralisation later this quarter.
