Lefroy has returned to the field with the resumption of two major, early-stage gold-focussed aircore drilling programs at its Lefroy project near Kalgoorlie.

At its wholly-owned Eastern Lefroy project, the company is carrying out a 9,000m drill campaign to evaluate multiple targets external to the exciting Burns copper-gold prospect while at Western Lefroy, its partner Gold Fields has recommenced a 46,000m program to cover most of the land area of the tenement package.

Lefroy Exploration (ASX:LEX) also expects to receive initial assay results from the holes completed at both projects in 2021 soon.

“We are excited to be back out drill testing multiple targets for gold and gold copper mineral systems nearby to Burns and beneath the vast Lake Randall,” managing director Wade Johnson said.

“Our campaign complements the recommencement of the land based FFAC drilling program by Gold Fields at Western Lefroy. In total +50,000m of early-stage drilling is being undertaken on these two fronts at the Lefroy Project.”

Eastern Lefroy drilling

The company had in November 2021 kicked off the second stage of a drill program aimed at assessing the limits of the Burns mineral system with targets generated from the detailed aeromagnetic survey completed in July 2021.

This program involves the use of a specialised lake aircore rig to evaluate aeromagnetic targets in Lake Randall immediately adjacent to and along the Burns corridor.

Prior to its suspension in mid-December for the year-end break after 199 vertical holes had been completed, the program generated additional drill targets in Lake Randall based on geological information derived from the recent campaign and interrogated with geophysical datasets.

Lefroy now expects to finish the remaining holes within six weeks with assays from the earlier drilling expected in February while the remaining results are due in April.

Results from this program and the October 2021 reverse circulation program will be combined to provide a broad geochemical and geological baseline framework over a 50sqkm area to focus more detailed drill evaluation at and or near to Burns in 2022.

Western Lefroy joint venture

Over at Western Lefroy, Gold Fields is carrying out an extensive aircore program as part of its $25m farm-in and joint venture agreement.

This involves the drilling of about 1,300 holes to cover most of the land area of the Western Lefroy tenement package to deliver foundation geological and geochemical information.

Gold Fields will combine this data with geophysical data to deliver specific targets for further aircore, RC and diamond drilling.

During the December quarter, 442 holes were completed. This included a closed-spaced program at Paddys Secret, the site of an alluvial gold find in 2013- 2014, where several large gold nuggets were discovered in a 400m by 200m area.
