Special Report: Lefroy Exploration’s (ASX:LEX) Burns gold-copper prospect near Kalgoorlie could be an intrusion related gold system like Hemi, or a porphyry system like Boddington. A 6000m drill program is now underway to find out.

Burns was discovered in 2011, after shallow drilling by a previous explorer hit thick zones of gold and copper like 50m at 0.9g/t gold and 0.5 per cent copper from 24m.

Burns lies on the eastern margin of a large ‘intrusion’, the majority of which is held by the Lefroy.

Intrusive rock is formed when often heavily mineralised magma (lava) penetrates existing rock, crystallises, and solidifies underground.

Lefroy says Burns is a priority exploration target for an intrusion related gold system, like Gruyere or Hemi, and porphyry gold-copper style of mineralisation like Boddington.

These are big, big deposits.

The only deeper drilling at Burns previously was angled away from this intrusion. It still managed to get sniffs of something significant.

Lefroy’s 25-hole drilling program is designed to test both strike and depth extensions to the Burns system.

Two holes will also be drilled into the main intrusion to assist in advancing the geological model.

“The unique geophysical signature, large geochemical footprint and associated gold, copper and silver mineralisation at Burns make it a very attractive target in the WA goldfields at a time of robust gold, copper and silver prices,” Lefroy managing director Wade Johnson says.

“We continue to grow the target portfolio at Eastern Lefroy and are very keen to complete this drill program at Burns that could deliver a very significant resource.”
