West Cobar Metals (ASX:WC1) outlines early gold footprint at Mystique Project

West Cobar Metals’ latest round of aircore drilling at its 100 per cent owned Mystique Project in Western Australia provides an early but noteworthy indication of gold mineralisation linked to structural features that warrant closer examination.

The results are drawn from a broad spaced program over two prospects, Themis South and Torquata, located 240 kilometres east of Kalgoorlie, and collectively point to the potential for a larger basement hosted system.

Highlights

• Sixty six aircore holes drilled for 4,262 metres across Themis South and Torquata
• Gold intersected in saprolite and bedrock, with grades up to 1 metre at 2.05 grams per tonne gold from 30 metres in MTA030
• Twenty eight holes returned anomalous gold values
• Mineralisation appears related to northwest to southeast structural trends interpreted from aeromagnetics
• Regolith complexity suggests a deeper basement target remains prospective

The program was designed to follow up historical gold intersections and to improve the geological understanding of the regolith profile, which has previously complicated interpretations.

While aircore drilling is inherently constrained by refusal at bedrock, West Cobar has extracted meaningful information from the bottom of hole samples, some of which carried anomalous gold values.

These results help frame a clearer picture of the subsurface environment and the movement of gold through weathered profiles.

Across the combined drill lines the most compelling intersections came from Themis South, where hole MTA030 returned a 4 metre composite at 0.27 grams per tonne from 28 metres, including a 1 metre photon assay of 2.05 grams per tonne from 30 metres and another metre at 1.23 grams per tonne from 40 metres.

This interval sits within a saprolite zone extending roughly 400 metres along Line 1. Additional low level anomalism in bottom of hole samples was recorded in MTA018, MTA010 and MTA060, with values between 0.12 and 0.60 grams per tonne.

These points align with interpreted northwest to southeast fault structures visible in aeromagnetic data, strengthening the structural context for ongoing work.

At Torquata the geological environment differs subtly, with gold detected in both saprolite and bedrock and minor grades also present in a paleochannel sequence containing conglomerate, grit and coarse sand.

A carbonaceous and pyritic mudstone within the cover sequence also carried trace gold, and these outcomes give the company an improved platform from which to reevaluate historical drilling in light of the updated regolith model.

West Cobar Metals Managing Director Matt Szwedzicki said the early stage results provided a useful foundation, noting that

“in the northern area, there is a 400 metre lateral zone of particular interest at Themis South related to interpreted NW SE trending structures which includes a gold grade up to 2.05 grams per tonne over 1 metre.”

With half of the holes returning anomalous values, the dataset offers enough encouragement to proceed with targeted follow up, and West Cobar plans to advance to tighter spaced drilling aimed at defining mineralisation along the structural trends in both saprolite and basement rocks.

While still at a reconnaissance stage, the work underscores the project’s potential within a region known for orogenic gold systems.

The identification of coherent structures, paired with recurring anomalism across multiple geological settings, positions Mystique for a more focused second phase of drilling that will clarify the scale and continuity of the basement targets.
