Gold mineralisation extended at Mt Martin

Gold mineralisation has been extended at Lefroy Exploration’s (ASX:LEX) Mt Martin gold mine in WA.

As part of the company’s maiden resource expansion drilling program, 29 reverse circulation (RC) holes were drilled to evaluate multiple extensions at depth and shallow gold-bearing shear structures.

Holes on the west side of the open pit targeted the northwest plunging ore shoots which are a feature of high-grade mineralisation at Mt Martin.

Best results include 35m @ 1.78g/t gold from 209m including 10m @4.32g/t gold from 222m, and 3m @3.74g/t gold from 128m.

These results are encouraging and confirm the mineralised structure have significant down-dip continuity that remains open at depth to the west of the existing resource.

There is significant potential for the discovery of additional shoot structures close to the existing resource where the controlling structures remain untested along strike to the north and south.

Holes on the east side of the pit were planned to confirm the near-surface continuity of the mineralised structures including the main shear and east shear.

This area has been subject to limited drilling which forms a gap in resource data immediately outside the open pit.

Best results from this drilling include 8m @ 3.98g/t gold from 38m including 4m @7.16g/t gold from 41m, and 3m @ 2.62g/t gold from 53m.

Results from these holes confirm the discovery of an entirely new shoot structure which remains open at depth and to the north. Lefroy considers these initial results to be very exciting as they highlight the potential for the discovery of additional new zones of mineralisation.

Overall, this maiden RC drilling program improved Lefroy’s confidence in the geological model by confirming the major shear structures as consistent controls on mineralisation.

These results will be integrated with the geological observation from the RC drilling and historical datasets to build an integrated targeting model to guide further exploration at Mt Martin.

Managing director Wade Johnson says the company is delighted with the results.

“We are delighted with the results from the recent drilling program at Mt Martin and now have a high degree of confidence in the geological model, with drilling confirming the main shears of consistent structures controlling mineralisation,” he said.

“The program has also identified new shallow gold mineralisation in the underexplored area immediately east of the open pit, which will now be a priority focus for follow-up drilling to provide an additional source of shallow open pit mineralisation.”

Lefroy will now focus its next phase of drilling on the eastern side of the pit at Mt Martin where there is strong potential for new shallow gold mineralisation.

Planning is underway with drilling scheduled to begin in early February. The aim of this drilling is to further expand the potential open-pit resource at Mt Martin and guide initial mining studies to assess options for project development.
