Kingston Resources says infill drilling at Jack’s Hut has confirmed the location and continuity of polymetallic mineralisation targeted for potential underground mining at Mineral Hill. The results will feed into a resource update, while surface drilling in October will test extensions beyond the current resource.
- 13.0m at 2.92% CuEq in KSNDDH091
- 9.3m at 3.17% CuEq in KSNDDH093
- Existing geological interpretation supported
- Surface drilling planned for October 2026
- Jack’s Hut resource update targeted for March quarter 2027
Drilling reinforces Jack’s Hut underground plan
Kingston Resources Limited (ASX:KSN) has strengthened the geological case for Jack’s Hut to become a second underground ore source at its Mineral Hill operation, with infill drilling confirming mineralisation where the company expected it around conceptual stope areas.
The results include 13.0 metres at 2.80% lead, 2.48% zinc, 0.76% copper, 0.88 grams per tonne gold and 16 grams per tonne silver, calculated at 2.92% copper equivalent, in hole KSNDDH091. Other notable intersections included 9.3 metres at 3.08% lead, 3.62% zinc and 0.97% copper at 3.17% CuEq in KSNDDH093, and 14.5 metres at 3.02% lead, 0.83% zinc and 0.44% copper at 2.37% CuEq in KSNDDH098.
Polymetallic zones show continuity across the deposit
The eight-hole program was designed to increase drill density in areas being assessed for future underground mining. Kingston says the results support the existing interpretation of two main lode components: an eastern copper-gold zone and a western zone with higher lead, zinc and silver.
Some narrower intervals were substantially richer. KSNDDH094 returned 2.05 metres at 2.39% copper and 5.44 grams per tonne gold, equivalent to 8.72% CuEq, while KSNDDH092 delivered 4.85 metres at 4.59% lead, 1.90% zinc and 1.51% copper, or 4.18% CuEq. These are downhole lengths rather than uniformly reported true widths, and the company notes that the relationship between intercept lengths and mineralisation width varies between holes.
Resource update and deeper drilling set the next test
Jack’s Hut currently contains an indicated resource of 608,000 tonnes and an inferred resource of 1.032 million tonnes. Kingston plans to incorporate the new assays into an updated geological model and mine-planning work, with a revised Jack’s Hut Mineral Resource estimate targeted for the March quarter of 2027.
A surface rig is expected at Mineral Hill in October 2026 to test potential down-dip extensions below the existing resource, as well as possible extensions along strike. The deposit has its own underground portal and decline, separate from the Southern Ore Zone, which Kingston identifies as an operational benefit if future mine planning supports its inclusion in production.
The CuEq figures are company-defined estimates based on specified commodity prices and metallurgical recoveries. They account for recovery assumptions but exclude smelting and refining costs, penalties and payabilities, so the headline equivalent grades are not a substitute for the forthcoming resource, mining and economic assessments.
Bottom Line?
The infill results reduce geological uncertainty at Jack’s Hut, but the more consequential test will be whether October step-out drilling and the 2027 resource model convert that confidence into mineable tonnes.
Questions in the middle?
- Will the October surface drilling extend mineralisation beyond the current Jack’s Hut resource envelope?
- How much of the updated resource can ultimately support mine planning and an Ore Reserve case?
- Can Jack’s Hut provide a practical second ore source alongside the Southern Ore Zone?
