• High-grade intercepts returned within planned near-term underground stoping areas
• Results strengthen the November 2025 Mineral Resource model
• Additional mineralisation identified in the footwall, presenting potential Resource growth and mine life extension upside

Kingston Resources Limited (ASX: KSN) is pleased to report strong assay results from underground infill drilling at Southern Ore Zone (SOZ) within the Mineral Hill Mine, confirming high-grade polymetallic mineralisation in areas scheduled for near-term underground stoping. The drilling targeted the initial underground stoping areas in Lodes A, B and C to infill the current drill pattern in preparation for production. The results materially de-risk the initial underground mine plan, confirm the geometry and continuity of the November 2025 Mineral Resource, and highlight additional mineralised zones in the footwall that represent potential Resource upside. Importantly, the ability to recover and sell multiple metals provides diversified revenue streams and enhances Net Smelter Returns (NSR). Elevated grades across gold, silver, lead and zinc are expected to positively impact margins as underground production ramps up. Mineral Hill is one of only two operating mines with full polymetallic processing capability in the Cobar region, positioning Kingston as a rare, leveraged exposure to multiple commodities in one of Australia's most proven precious and base metal provinces.

The Company is focused on meeting near mine production targets located on the existing MLs. The aim is to extend the mine's life through organic growth and consider regional deposits that could be processed at Mineral Hill's processing plant.
