Can Legend Mining’s New Geophysical Target Unlock Gold at Pinnacle Well?

Expanding the Exploration Footprint

Legend Mining Limited has announced a significant extension of a chargeable-resistive geophysical feature at its Pyrophyllite Hill prospect, part of the Pinnacle Well Project located 25 kilometres north-northeast of Leonora in Western Australia. Recent infill geophysical surveys have expanded this key anomaly to approximately 600 metres in strike length, deepening from around 75 metres to 400 metres below surface.

This feature is interpreted to represent disseminated sulphides associated with silica alteration and quartz veining, which are classic indicators of potential gold mineralisation. The anomaly aligns with a large pyrophyllite alteration zone and a multielement hydrothermal signature detected in soil samples, reinforcing its prospectivity.

Geophysical and Geochemical Synergy

The chargeable-resistive feature was initially identified through pole-dipole induced polarisation (PDIP) and gradient array induced polarisation (GAIP) surveys. Follow-up infill PDIP lines confirmed the lateral continuity and depth extent of the anomaly, which trends northwest-southeast consistent with regional structural controls, notably the Keith-Kilkenny Fault Zone.

Complementing the geophysical data, ultra-fine fraction soil sampling revealed anomalous concentrations of elements such as silver, cadmium, mercury, antimony, and arsenic, all indicative of a hydrothermal system. This geochemical footprint, combined with the extensive pyrophyllite alteration mapped over an area of approximately 1300 by 700 metres, paints a compelling picture for intrusion-related and structurally controlled gold mineralisation.

Pathway to Drilling

Legend’s Executive Chair, Mark Wilson, emphasised the significance of these findings, noting the chargeable-resistive feature’s potential as a drill target. The company plans to undertake further ground truthing and detailed 3D geophysical modelling to refine drillhole designs. Heritage clearances are also underway, paving the way for the next phase of exploration drilling.

Historical rockchip samples near the anomaly returned anomalous gold values, albeit modest, which adds to the encouragement for drilling. The Pinnacle Well Project itself is strategically positioned within a prolific gold region, hosting several major deposits, which further underlines the potential of the Pyrophyllite Hill prospect.

Strategic Implications

This extension of the geophysical anomaly and its alignment with alteration and geochemical signatures represent a meaningful step forward in Legend Mining’s exploration campaign. While no drilling results have yet been reported, the groundwork laid by these surveys enhances the likelihood of discovering economically viable gold mineralisation.

Investors and industry watchers will be keenly observing the upcoming drilling results, which will be critical in validating the interpreted mineralisation and potentially unlocking significant value for the company.
