Emetals Limited has returned significantly higher tungsten grades from re-assayed underground grab samples at the Mineral Range Tungsten Project in Beaver County, Utah.

The re-assay program focused on eight underground grab samples (MM027–MM034) previously collected from the historic Garnet Mine. Following a review of analytical techniques, Emetals shifted from an original four-acid digestion method with an ICP-AES finish to a lithium-borate fusion XRF method. The company determined that the previous acid digestion technique understated tungsten values in coarser-grained mineralisation because it fails to achieve total digestion of refractory tungsten-bearing minerals.

The fusion-based method confirmed substantially higher grades across all re-analysed rock chips. Multiple high-grade samples were returned, including 3.83% WO₃ compared to an initial 0.74% reading, 1.91% WO₃ up from 0.14%, 1.66% WO₃ up from 0.10%, and 0.95% WO₃ compared to the previous 0.41% result.

These findings establish the analytical approach for upcoming work at the property. Emetals expanded its footprint at the project in August 2026 to 145 mineral claims covering 2,782 acres along a 12-kilometre strike length of the Mineral Range batholith.

The company has scheduled a 17-hole diamond core drilling campaign at Mineral Range to commence in September 2026, with individual hole depths ranging from 50 to 200 metres across five drill pads.

“These significantly higher-grade further results from the coarser grained samples are encouraging and it has now been determined that the fusion-based assay methodology will be adopted for the drilling campaign scheduled to commence in September”
