Perpetual Resources has secured a definitive agreement to acquire the historic Nevada Scheelite tungsten mine, bolstering its critical minerals portfolio with high-grade assets in the US and Brazil. Concurrently, exploration at its Brazilian lithium and tungsten projects progresses, supported by recent assay results and metallurgical advances.
- Definitive agreement to acquire 100% of Nevada Scheelite tungsten project
- Historical drilling confirms high-grade tungsten mineralisation up to 2.40% WO₃
- Brazilian lithium project trenching reveals extensive pegmatite trends
- Paraíba tungsten reconnaissance yields assays up to 1.53% WO₃
- Beharra silica sand metallurgical tests reduce iron impurities significantly
Nevada Scheelite Acquisition Sets New Benchmark
Perpetual Resources (ASX:PEC) has taken a decisive step in expanding its critical minerals footprint by entering into a definitive agreement to acquire a 100% interest in the Nevada Scheelite tungsten project in Mineral County, Nevada. This historic brownfield mine, with recorded production of approximately 328,747 short ton units of WO₃ at an average grade of around 1.1% between 1937 and 1957, offers a rare combination of high-grade mineralisation and existing underground infrastructure including two shafts and over 2,100 metres of drifts across six levels.
The acquisition covers four patented mining claims, granting Perpetual private ownership of both mineral and surface rights, a strategic advantage likely to streamline permitting and development timelines compared to public land holdings. Historical drilling results underscore the project's potential, with intercepts such as 8.2 metres at 2.40% WO₃ and 4.0 metres at 1.34% WO₃, alongside underground face sampling averaging grades up to 1.80% WO₃. While these figures are drawn from legacy data not compliant with current JORC standards, they provide a compelling foundation for Perpetual’s planned geological modelling and maiden resource evaluation.
Digitising a Century of Data to Modernise Exploration
Perpetual has secured access to an extensive historical database comprising over 400 drill holes, mine plans, cross-sections, and geological maps, much of which was generated by previous operators and US government agencies including Union Carbide and the Bureau of Mines. The company is systematically digitising and validating these records to build a modern 3D geological model of the Nevada Scheelite system, which will underpin targeted confirmatory drilling and resource definition. Additionally, a substantial collection of preserved diamond drill core is being catalogued, potentially enabling relogging, confirmatory assays, and metallurgical testing to refine the project’s economic prospects.
Brazilian Exploration Accelerates with Lithium and Tungsten Targets
In Brazil, Perpetual continues to advance its critical minerals strategy with focused exploration at the Igrejinha Lithium & Caesium Project and the Paraíba Tungsten Project. A trenching program at the Mauricio target within Igrejinha has confirmed pegmatite exposures up to 11 metres thick, tracing an interpreted trend of approximately 167 metres that remains open in multiple directions. Over 40 channel samples have been collected for assay, with results pending to guide a planned drilling campaign later in 2026.
The Paraíba Tungsten Project, situated in South America’s premier tungsten-producing Seridó Mineral Province, saw its maiden reconnaissance program return promising high-grade rock-chip assays. Peak tungsten grades reached 1.53% WO₃, with six samples exceeding 0.50% WO₃ across three distinct target areas, including zones beyond previously known artisanal workings. These results validate initial geological targeting and set the stage for expanded mapping, sampling, and future drilling to delineate skarn-hosted tungsten mineralisation.
Beharra Silica Sand Progresses Towards Premium Glass Markets
Back in Australia, metallurgical test work on the Beharra Silica Sand Project delivered a significant reduction in iron oxide content, achieving 110–120 ppm Fe₂O₃, down from approximately 760 ppm in the raw feed and improving on earlier results of 150 ppm. This product quality approaches the sub-100 ppm threshold typical for solar glass applications, attained through a straightforward flowsheet involving classification, gravity separation, and high-gradient magnetic separation. While the product does not yet meet the strictest specifications for solar or borofloat glass, it is considered suitable for several premium glass types, with further testing planned to confirm heavy mineral content and market suitability.
Capital Raise Supports Growth and Exploration
To fund the Nevada Scheelite acquisition and ongoing technical programs, Perpetual completed a placement raising approximately $2.5 million at $0.02 per share. The company ended the quarter with $2.34 million in cash, having used $460,000 in operating activities and $201,000 on investing, including exploration and tenement acquisition costs. Payments to related parties totalled $116,000 for directors’ fees and executive remuneration.
Looking ahead, Perpetual’s near-term agenda prioritises advancing the Nevada Scheelite acquisition, digitising and validating historical data, undertaking geological site assessments, and developing a 3D model to identify drilling targets and progress towards a maiden JORC Mineral Resource. Concurrently, the company aims to interpret pending assay results from Brazil, refine drilling targets at Igrejinha, and define the next exploration phase at Paraíba. Beharra’s commercial pathway will also be assessed in light of recent metallurgical gains.
Bottom Line?
Perpetual Resources’ acquisition of Nevada Scheelite marks a pivotal expansion into high-grade tungsten, complemented by advancing lithium and tungsten projects in Brazil and metallurgical progress in Australia, execution of resource definition and assay results will be critical to unlocking value.
Questions in the middle?
- Will Perpetual complete the Nevada Scheelite acquisition on schedule and meet all transaction conditions?
- How will pending assay results from Brazilian lithium and tungsten projects influence drill targeting and capital allocation?
- Can further metallurgical improvements at Beharra silica sand push the product into the lucrative solar glass market?
