Perpetual Resources Limited has identified 22 drill holes containing tungsten intervals at or above a 0.2% WO3 threshold following an initial review of archival data from the Nevada Scheelite Tungsten Project in Mineral County, Nevada.

The review of an initial 42-hole tranche, representing about 10% of the project's drilling archive, recovered digitised records from 1968 campaigns by former operator Union Carbide Corporation. Notable downhole intercepts include 7.01m at 1.95% WO3 in hole 5-DH-02, 7.59m at 1.50% WO3 in hole 4-DH-11, 8.60m at 1.10% WO3 in hole 5-DH-09, and 5.49m at 1.54% WO3 in hole 5-DH-07.

Collar coordinates and downhole survey data have been located and cross-checked for 29 of the 42 historical holes, including the 22 mineralised intersections. A further 13 records remain excluded from quantitative tabulation pending confirmation of collar or survey information. The company notes that the historical exploration results are unverified, lack complete sampling, QA/QC and internal dilution records, and true widths are currently unknown. The data does not establish a Mineral Resource and geological continuity is not asserted.

Perpetual acquired a 100% interest in the Nevada Scheelite Mine via staged payments in June 2026. The technical team subsequently mobilized to conduct underground reconnaissance, 3D LiDAR surveying, and safety assessments at the property.

The digitised historical database is targeted for completion and integration within approximately four weeks from late August 2026. The company intends to use the historical grade and spatial data to build an integrated 3D geological model, which will guide modern validation and extension drilling across the skarn contact and at depth. Portions of surviving diamond drill core remain stored on-site and in Fallon, Nevada, for potential auditing and modern re-assay testing.

The regional skarn-hosted tungsten setting has also seen exploration activity nearby, with Guardian Metal Resources plc having reported the discovery of the Tremor Zone at its Pilot Mountain tungsten project within the surrounding district.
