Perpetual Resources (ASX:PEC) has identified tungsten intervals in 22 historical drill holes at the Nevada Scheelite Tungsten Project in Nevada, US, as it prepares to validate the results and plan further drilling.
The company is advancing an option to acquire the patented claims covering the former mine in Mineral County.
Its initial review covers 42 holes, with records reporting intervals at or above 0.2% tungsten trioxide (WO₃) in 22 of them.
Highlights include 7.01m @ 1.95% WO₃ from 5.55m downhole in 5-DH-02 and 7.59m @ 1.50% WO₃ from 28.35m in 4-DH-11.
Other historical intervals include 8.60m @ 1.10% WO₃ from 14.87m in 5-DH-09 and 5.49m @ 1.54% WO₃ from 8.84m in 5-DH-07.
These are unverified historical results, with incomplete sampling, quality-control, and internal dilution records. True widths are unknown, and the results neither establish a mineral resource nor demonstrate continuity between holes.
Executive Chairman Julian Babarczy says the archive will help guide modern exploration.
“While these historical results require modern validation, they provide a strong foundation for our 3D geological model and future drilling to test the potential for mineralisation to continue along the skarn contact and at depth,” Babarczy says.
The wider archive contains records from more than 400 drill holes and individual sampling locations, alongside mine plans and geological cross-sections.
Perpetual has confirmed that the historical drill core sometimes survives in underground storage at the site or regional facilities in Fallon. It says it plans to audit available core and conduct re-assaying where appropriate.
The company says it expects to integrate validated data into a 3D geological model within four weeks, supporting the design of validation and resource definition drilling.
Perpetual is a critical minerals explorer and developer with interests in the US, Brazil, and Australia.
