Guardian Metal finds tungsten 'Tremor Zone'

Guardian Metal Resources said on June 4 that it had identified a new tungsten-mineralized area called the Tremor Zone at its 100%-owned Pilot Mountain project in Nevada. The company said the zone was found during condemnation drilling over a blind target that had also been assessed as a possible mine-infrastructure location as part of the project’s ongoing pre-feasibility study. Guardian described the find as a new tungsten-skarn zone within a project it has been advancing as part of a broader U.S.-focused tungsten strategy. ### Where exactly was the Tremor Zone found? Pilot Mountain is in Mineral County, Nevada, about 19 air-kilometers east of Mina, according to Guardian’s project page. The company said the Tremor Zone sits within its 100%-owned Pilot Mountain Tungsten Project, which it is advancing alongside the Tempiute project in Nevada. Guardian’s published project materials describe Pilot Mountain as a multi-deposit property where the current mineral resource estimate is based only on the Desert Scheelite deposit.

The company said the target was “blind,” meaning it is covered by alluvium and does not outcrop at surface, and was tested through reverse-circulation condemnation drilling tied to infrastructure planning for the pre-feasibility study. (guardianmetalresources.com) June 4 disclosure from the company said the initial discovery hole, PMR26-077, cut five tungsten-rich skarn intervals. The headline intercept was 13.68 meters at 0.31% WO3 from 102.11 meters to 115.82 meters downhole, with additional intervals of 3.04 meters at 0.24% WO3 from 83.83 meters, 4.56 meters at 0.16% WO3 from 118.87 meters, 1.52 meters at 0.24% WO3 from 143.26 meters, and 4.56 meters at 0.24% WO3 from 152.4 meters, the company said.

Condemnation drilling is used to test whether ground being considered for mine infrastructure also contains mineralization that could affect layout decisions. Guardian said that is what led it into the Tremor target area while the Pilot Mountain pre-feasibility study was under way. The company added that the study is nearing completion and said that work has been supported by a $6.2 million U.S. (accessnewswire.com) Defense Production Act Title III investment in its wholly owned subsidiary, Golden Metal Resources (USA) LLC. ### What is already known about Pilot Mountain? Guardian’s project page says Pilot Mountain hosts a pit-constrained mineral resource estimate of 8.694 million indicated tonnes grading 0.206% WO3 and 1.784 million inferred tonnes grading 0.169% WO3, with silver, copper and zinc credits. The company says that estimate covers only one of the property’s four deposits, Desert Scheelite, and is based on 68 drill holes completed in 2024 and 2025. (accessnewswire.com) Project materials published by Guardian say baseline environmental data collection, rock geochemical characterization and hydrological work are being folded into the pre-feasibility study and later permitting. The company also says additional drilling completed after the December 2025 resource cutoff is expected to feed into a further updated mineral resource estimate before the pre-feasibility study is finalized.

Guardian said additional follow-up holes have already been drilled after PMR26-077, with PMR26-078, PMR26-079, PM26-088, PM26-096 and PM26-097 all intersecting visually identified tungsten-bearing skarn over approximate widths of 12 meters, 28 meters, 66 meters, 14 meters and 38 meters, respectively. The company said drilling is continuing as it tests extensions to the new zone while Pilot Mountain’s pre-feasibility study approaches completion. (guardianmetalresources.com) (accessnewswire.com)
