Resource Upside and Margin Expansion Loom as Kingston De-Risks Underground Mine Plan
Kingston Resources reports robust high-grade polymetallic assay results from underground drilling at Mineral Hill, reinforcing resource confidence and de-risking near-term mining plans.
- Strong high-grade polymetallic intercepts in Southern Ore Zone underground stoping areas
- Results validate and enhance November 2025 Mineral Resource model
- Additional mineralisation identified in footwall, suggesting resource growth potential
- Polymetallic processing capability supports diversified revenue and margin expansion
- Ongoing drilling and underground development to optimise mine planning and extend mine life
Robust Assay Results Strengthen Mineral Hill Outlook
Kingston Resources Limited (ASX, KSN) has released compelling assay results from its recent underground infill drilling campaign at the Southern Ore Zone (SOZ) of the Mineral Hill Mine in New South Wales. The high-grade polymetallic intersections, encompassing gold, silver, lead, zinc, and copper, not only confirm but also enhance the Mineral Resource model updated in November 2025. These results materially de-risk the initial underground mine plan, providing greater confidence in the geometry and continuity of the deposit.
Polymetallic Mineralisation and Strategic Processing Advantage
The Mineral Hill Mine remains one of only two operating mines in the Cobar region equipped with full polymetallic processing infrastructure. This capability allows Kingston to produce multiple metal concentrates and precious metal doré on site, diversifying revenue streams and improving net smelter returns. Elevated grades across the metals portfolio are expected to positively influence margins as underground production ramps up, underscoring the strategic value of Mineral Hill’s established processing plant.
Resource Growth and Mine Life Extension Potential
Beyond confirming planned stoping areas in Lodes A, B, and C, the drilling identified additional mineralisation in the footwall zones. This discovery opens the door to potential resource growth and an extension of the mine life beyond the current six-year plan. Kingston’s Managing Director and CEO, Andrew Corbett, highlighted the ongoing drilling program and underground development as key to refining mine planning and unlocking further value from the deposit.Technical Rigor and Future Exploration
The drilling program employed oriented diamond core techniques with rigorous sampling and quality control protocols, ensuring the reliability of assay data. The company plans to continue underground diamond drilling and level development at SOZ, alongside open pit gold and silver production at Pearse South. These activities aim to sustain a steady pipeline of results to optimise resource conversion and operational efficiency.Kingston’s polymetallic focus in a proven mining province, combined with its processing flexibility, positions the company well to capitalise on commodity price dynamics and operational leverage. The latest results reinforce Mineral Hill’s status as a significant polymetallic asset with promising upside.
Bottom Line?
Kingston’s strong polymetallic results at Mineral Hill set the stage for resource growth and margin expansion as underground production accelerates.
Questions in the middle?
- How will the 2% Net Smelter Return royalty affect overall project economics?
- What are the timelines and expected impact of ongoing drilling results on resource upgrades?
- To what extent can additional footwall mineralisation be converted into Ore Reserves?
