PROOF-OF-CONCEPT DRILLING PROGRAM

Under-developed Goldfield

Wedderburn is one of Victoria’s under-developed goldfields, it has a geographical footprint comparable to other moderate-sized goldfields in the Bendigo Zone. Clive Willman & Associates (Willman) geological mapping (bedding, cleavage & younging) of the surface outcrops on the EL classified various clusters of united reefs into Western, Central and Eastern Groups as depicted below.

Western Group

The Western Group has clusters of auriferous reefs in the south, including Shaw’s Reef, featuring the New Caledonian Mine, which produced the most recorded shaft-gold on the Wedderburn goldfield. The Potter’s Reef clusters include an “addit” (horizontal shaft into a side of a hill). The Enterprise cluster of reefs has several shallow shafts, as does the Tambourine cluster of reefs. The Western Group has a strike length of some six kilometres.

Central Group

The Central Group of auriferous reefs includes Lane’s Corridor, the subject of WGL’s 2022, 3317 metre diamond-drilling program described in Exploration Information No 3 Dec 22. As well as the “Lanes Corridor” reefs, and other reef structures, the Central Group of auriferous reefs include Bocca Flat, where much alluvial gold was extracted historically and currently, by modern day metal detector operators. A local resident is quoted as saying, “when the Bailiffs at the door I take the metal detector to Bocca Flat it has never failed me yet!”

Eastern Group

The Eastern Group of auriferous reef clusters include the Old Christmas, Buckeye, Robinson’s, Annie Jone’s and Shamrock Reefs. All these reefs have shallow shafts, only to the depth of the water table, (say 50m) with historically noted anticlines, synclines and cross reefs. (As in the Western and Central Groups).

There are many “lineaments” (interpreted cross faults) situated on the EL resulting from the current diamond drilling exploration results. Geophysical exploration techniques will now be focused on the 10km strike length of unexplored auriferous reefs which have never been subjected to modern exploration.

Completed Proof-of-Concept Drilling Program

WGL successfully completed a circa 3,317 metre diamond drilling campaign centred on Lane’s Corridor.

The central group of reefs was chosen for detailed exploration because more data existed, not because it was considered more prospective.

Twelve holes, LDH 001 to 011, were drilled in the central group of auriferous reef clusters (Lane’s Corridor) at flat angles circa azimuth 30° with downhole lengths of 120-150 metres.

Four holes, DH 001 to 004 were drilled at azimuth angles of 51° with downhole extents of about 400 metres.

Successfully Delineated a newly Interpreted Regional Syncline & Associated Anticlines

WGL’s 3,300-metre proof-of-concept diamond drilling program successfully delineated a newly interpreted regional syncline and associated anticlines.

The synclines and anticlines extend across the full 1.75 km drill corridor.

The eastern limb of this syncline is confirmed to be gold-mineralised within a narrow quartz vein.

This is supported by assay data and historical shallow shaft workings.

Targets Identified in Hinge Zone of Regional Syncline

Wedderburn’s new underground interpretation of the 1.75 km position of the regional syncline allows for future testing of multiple targets including:

Hinge Zones
Mineralized Cross Faults
Mineralised Drill-Hole Intersections
