How Deep Does Pennyweight Point’s High-Grade Gold Go? Arika Finds Out 100m Lower

Exploration Breakthrough at Depth

Arika Resources Limited (ASX, ARI) has delivered a major exploration update from its Yundamindra Gold Project in Western Australia, revealing thick, high-grade gold mineralisation intersected 100 metres below previous drilling at the Pennyweight Point prospect. The standout result from the latest drilling campaign is a 10-metre intercept grading 9.02 grams per tonne gold, including a 6-metre section at 13.87 grams per tonne, confirming the continuity of mineralisation to at least 250 metres vertical depth and still open.

This discovery marks the deepest hole drilled at Pennyweight Point to date and ended in high-grade mineralisation, underscoring the potential for a larger, vertically extensive gold system than previously understood. The mineralised zone remains unconstrained at depth, with plans to re-enter and extend the hole using diamond drilling techniques to better define the extent.

Building on a Strong Foundation

The recent results build on a series of encouraging intercepts from earlier in the year, including broad zones of low to high-grade gold mineralisation and narrower high-grade intervals. Previous holes reported intercepts such as 23.97m at 2.54g/t Au and 14m at 15.48g/t Au, reinforcing Pennyweight Point as a priority target within the Eastern Corridor of the Yundamindra Project.

Arika’s Managing Director, Justin Barton, highlighted the significance of the breakthrough, noting the consistency of the mineralised structure and the predictive accuracy of their geological modelling. The confirmation of mineralisation continuity down-dip and down-plunge not only validates the exploration strategy but also expands the potential mining envelope.

Strategic Drilling and Future Prospects

To date, the company has drilled over 23,000 metres in this campaign, with assays awaited for 30 holes totaling approximately 5,500 metres. The ongoing program targets extensions along strike and at depth, including testing new geophysical targets identified at the intersection of the Landed at Last and F1 structures.

The Yundamindra Gold Project sits within the prolific Laverton Greenstone Belt, a region known for world-class gold deposits. The recent findings at Pennyweight Point suggest the potential for both open pit and underground mining operations, which could significantly enhance the project’s value proposition.

Technical Rigor and Confidence

The drilling program employs industry-standard Reverse Circulation and diamond drilling techniques, with rigorous sampling and assay protocols overseen by qualified personnel. The alignment of drill results with predictive models has increased confidence in the geological interpretation and resource potential.

Looking ahead, Arika plans to continue drilling through early 2026, focusing on expanding known mineralisation and testing new targets revealed by recent geophysical surveys. The company’s systematic approach and strong technical foundation position it well to unlock further value from the Yundamindra Gold Project.
