Kingston Resources Extends High-Grade SOZ Mineralisation at Mineral Hill

Strong Drilling Results Extend Mineralisation at Southern Ore Zone

Kingston Resources (ASX:KSN) has announced a significant extension of the high-grade upper A Lode at the Southern Ore Zone (SOZ) within its Mineral Hill polymetallic mine in NSW. New assay results from diamond drilling hole KSNDDH085 reveal a continuous mineralised zone stretching east and south, with the lode remaining open in both directions. This extension underpins a substantial portion of the SOZ Mineral Resource and opens the door for further resource growth in upcoming updates.

The standout intercept in KSNDDH085 returned 77.10 metres grading 0.62 g/t gold, 0.66% copper, 4.07% lead, 2.49% zinc, and 53 g/t silver from 154 metres downhole, including a 22.10 metre section with notably higher grades of 1.62 g/t gold, 1.47% copper, 8.98% lead, 3.13% zinc, and 132 g/t silver. The polymetallic nature of the mineralisation, particularly the high lead and zinc grades, was visually confirmed in core photos showing solid galena sections. Complementary drilling hole KSNDDH086, drilled beneath 085, also delivered strong results, validating the existing geological model.

Northern Extensions and Infill Drilling Support Resource Confidence

Additional drill holes KSNDDH068, 069, and 079 targeted the northern end of the SOZ, intersecting high-grade copper-gold mineralisation within the G and H Lode areas. Highlights include 8 metres at 2.27 g/t gold and 1.50% copper from 54 metres in KSNDDH079, and multiple intercepts in KSNDDH069 featuring up to 4.43 g/t gold and 1.33% copper. These results not only infill existing resource gaps but also extend mineralisation further north, reinforcing confidence in the deposit's scale and continuity.

Managing Director Andrew Corbett emphasised the significance of these results, noting the upper A Lode as one of the highest-grade zones in SOZ. He highlighted the company’s commitment to a 25,000-metre drilling program planned for FY27, which includes efforts to secure surface drilling approvals to explore extensions adjacent to the current underground workings. Corbett described the findings as bolstering confidence in the SOZ system’s scale and supporting plans for a larger, longer-life underground operation.

Resource and Reserve Base Remains Robust Amid Expansion

The Southern Ore Zone currently holds a combined Measured, Indicated, and Inferred Mineral Resource of approximately 6.54 million tonnes at 1.08 g/t gold and 0.83% copper, among other metals. The Probable Ore Reserve stands at 700,000 tonnes grading 1.40 g/t gold and 0.80% copper. The new drilling results are expected to contribute positively to future resource and reserve updates, with the polymetallic nature of the deposit offering a diversified revenue base including gold, copper, lead, zinc, and silver.

Kingston’s metallurgical strategy involves producing multiple concentrates and precious metal doré on site, with flotation circuits for copper, lead, and zinc planned to optimise recovery. The company’s approach aims to stabilise cash flow across commodity cycles by broadening its metal exposure.

Ongoing Drilling and Future Catalysts

Drilling continues at the SOZ, focusing on potential extensions within the G and H Lode areas. Several drill holes remain pending assay results, which could further refine the geological model and resource estimates. The company’s aggressive drilling schedule and pursuit of surface drilling approvals will be key to unlocking additional mineralisation and advancing Mineral Hill’s underground development.

With recent capital raises securing funds for this expansive drilling campaign and plant expansion, Kingston is positioning Mineral Hill for sustained growth and operational scaling. The market will be watching for forthcoming assay releases and resource updates that could materially impact the mine’s valuation and production profile.
