Lefroy just hit 18 metres grading 6.5g/t gold at Lucky Strike
Special Report: Lefroy has hit an incredible best-ever intersection at the aptly named Lucky Strike gold project near Kalgoorlie. This emerging mineralised corridor is now 320m-long and growing fast.
In June, Lefroy (ASX:LEX) hit a game changing intersection at the greenfields (unexplored) Lucky Strike prospect – 21m grading ~3g/t gold, 139m from surface.
The gold was found in a deeply oxidized Banded Iron Formation (BIF) – a type of rock composed of narrow banded sediments which is generally associated with iron ore deposits, not gold.

This oxidised ‘corridor’ is where Lefroy is getting a number of consistently thick, high grade gold intersections.
A recent 27 hole, 4274m drilling program tested an additional 320m of this corridor at Lucky Strike.
Today, Lefroy announced its best ever intersection — confirming that gold mineralisation does, in fact, extend a further 320m along strike and remains open.
This 18m intersection grading 6.57g/t gold from 68m in LEFR140 included a 4m chunk grading an incredible 21.9g/t.
Anything above 5g/t is generally considered high grade.
The next stage of RC drilling will kick off in October. Lefroy says this will include closer spaced drilling around the newly discovered high-grade shallow gold intersections announced today.
“Gold mineralisation in the BIF package at Lucky Strike now has a strike length of 780m and remains open to the south east,” the company says.
But this deeply oxidised BIF unit – which is associated these big gold hits — is over 3km long. The upside here is huge.
“The results from the recent phase of step out RC drilling provide further support for the interpretation that Lucky Strike is part of a larger mineralised structural trend,” Lefroy says.
