Koba Resources (ASX:KOB) has commenced its maiden 3,000m drill program at the Mt Garnet Tin-Tungsten Project in North Queensland.
The program targets the Stannex Prospect, which has a 2km by 0.5km tin-in-soil anomaly coinciding with strong induced polarisation chargeability anomalies and rock chip samples grading up to 21.30% tin (Sn).
Drilling will also test the historic Gilmore Mine, which produced 26,169 tonnes @ 7.3% Sn and where previous drilling returned intersections including 1m @ 5.2% Sn, 3m @ 1% Sn, 3m @ 1.2% tungsten (W), and 3m @ 0.95% W.
“The drill program will initially target the high-priority Stannex Prospect that presents as a well-defined drill target that extends over more than 2km of strike, supported by coincident high tenor tin-in-soil anomalies, strong geophysical anomalies and high-grade surface mineralisation up to 21.3% Sn,” Managing Director Ben Vallerine says.
“The program will also target the nearby high-grade, historical Gilmore Mine that produced 26,169 tonnes @ 7.3% Sn. Our initial drilling here will follow-up on multiple intersections of high-grade tin and tungsten mineralisation in limited previous drilling.”
The recently completed induced polarisation survey at Stannex identified ‘strong’ lateral continuity and ‘significant’ depth extent across the target.
Koba acquired the Mt Garnet and Stannary Hills tin-tungsten projects in Queensland in October 2025. The company reported ‘high-grade’ tin results from initial sampling at Mt Garnet in December 2025.
Following completion of the Mt Garnet program, the company plans to commence a 3,000m drill program at the Kitchener and Jiminy prospects within the Stannary Hills Tin-Tungsten Project in the September quarter of 2026.
Assay results from recent tungsten-focused rock chip sampling at Mt Garnet are expected in July 2026 to further define the project’s tungsten potential.
