Koba Resources has delivered strikingly high tungsten and tin assays from its initial sampling at Queensland's Mt Garnet Project, advancing drilling and exploration plans.
- Tungsten assays up to 13.2% W from 44 rock chip samples
- High-grade tin results up to 7.7% Sn alongside tungsten
- Six priority prospects identified for immediate follow-up
- Maiden 3,000m drilling program progressing with 2,267m completed
- Systematic soil sampling and mapping scheduled to refine drill targets
Exceptional Tungsten Grades Highlight Mt Garnet Potential
Koba Resources (ASX:KOB) has unearthed remarkably high-grade tungsten mineralisation in its inaugural tungsten-focused reconnaissance program at the Mt Garnet Tin-Tungsten Project in Queensland. The company collected 44 rock chip samples across multiple prospects, returning assays as high as 13.2% tungsten (W) and 7.7% tin (Sn), underscoring the widespread nature of high-grade mineralisation within the project area.
Among the standout results, the Starlight Prospect yielded the highest tungsten assay of 13.2% W over an 800-metre strike length, while the Gows Prospect delivered up to 5.4% W across 500 metres. Other prospects such as Ahmets, Crest, Mountain Maid, and Tungsten Knob also returned significant tungsten grades, reinforcing the project's potential as a polymetallic system.
Prioritising Six Key Prospects for Follow-Up
The recent sampling has enabled Koba to prioritise six tungsten prospects for immediate follow-up work. The Gows Prospect stands out with multi-element mineralisation including 3.2% tin, 35.4% copper, and notable gold and silver values, hinting at a complex mineral system beyond tungsten alone. Similarly, the Starlight Prospect combines high-grade tungsten rock chips with a historic tin-in-soil anomaly, providing a compelling target for further investigation.
Additional soil sampling, mapping, and rock chip sampling are scheduled to commence in August. These programs aim to delineate mineralised trends, assess their extent, and refine drill targets. The company plans systematic soil sampling across the 1.5-kilometre quartz-greisen vein at the Crest Prospect and intends to expand soil surveys at Mountain Maid, Ahmets, and Tungsten Knob to better understand mineralisation controls and scale.
Drilling Progress and Next Steps
Koba's maiden 3,000-metre drilling campaign at the Mt Garnet Project is advancing steadily, with 19 holes completed for 2,267 metres targeting high-grade tin-tungsten mineralisation at the Stannex and Gilmore Prospects. Assay results from this drilling are pending, but the program is positioned to deliver critical data on the project's resource potential.
Following completion of the Mt Garnet drilling and receipt of the final permit, the rig is scheduled to move to the Stannary Hills Tin-Tungsten Project to test high-priority targets there. This next phase includes a planned ~3,000-metre drill program at the Kitchener and Jiminy Prospects, further expanding Koba's exploration footprint in Queensland.
Strategic Implications for Koba's Exploration Pipeline
The combination of extremely high-grade surface assays and ongoing drilling underscores a robust pipeline of tungsten and tin targets for Koba. The polymetallic nature of mineralisation at prospects like Gows, with significant copper and precious metals, adds an intriguing dimension to the project’s exploration upside. The systematic approach to soil sampling and mapping will be critical in refining the scale and continuity of mineralisation ahead of resource definition drilling.
While assay results from the current drilling remain awaited, the early-stage results provide a strong foundation for Koba’s exploration strategy in a market environment increasingly attentive to critical minerals such as tungsten and tin. The company’s ability to advance multiple prospects simultaneously positions it well to capitalise on these emerging opportunities.
Bottom Line?
Koba’s high-grade tungsten assays and advancing drill programs set the stage for a pivotal phase in defining the Mt Garnet Project’s resource potential.
Questions in the middle?
- Will upcoming soil sampling confirm and expand the high-grade tungsten trends at key prospects?
- How will assay results from the ongoing 3,000m drilling program influence Koba’s resource estimates and project valuation?
- What role could the polymetallic nature of mineralisation at Gows play in shaping future exploration priorities?
