en.Wedoany.com Reported - Perpetual Resources (ASX:PEC) has completed its first field geological visit to the Nevada Scheelite project, a high-quality brownfield tungsten project located in Nevada, USA. The visit covered the project area, historical mine infrastructure, surface outcrop geology, key structural features, and preliminary rock chip sampling.
PEC Executive Chairman Julian Babarczy stated that this visit marks a significant milestone for the project, directly confirming several key features that attracted the company, including clear surface expressions of a tungsten skarn system, visible garnet-pyroxene skarn (tactite), mappable skarn-limestone contacts, and alteration minerals consistent with a typical intrusion-related tungsten skarn environment. He specifically noted that the structural geometry observed at the surface aligns with the strike of historical underground workings, supporting the historical geological model and laying the foundation for the next phase of technical work.
Tungsten is classified as a critical mineral and is an essential material required by defense technology companies and advanced manufacturers. The United States is currently actively developing its domestic tungsten supply chain to reduce dependence on supplies from China and Russia.
During the field visit, observations were recorded at two structural sites, Outcrop 1 and Outcrop 2. The company reported that clear, mappable contact interfaces between garnet-pyroxene skarn (tactite) and carbonate host limestone were observed at both locations. The surface structural geometry is broadly consistent with the strike of historical underground workings, indicating alignment between surface geology and the historical model, and supporting the potential continuity of the mineralized skarn system at depth. To characterize the main lithological units and alteration facies and provide an initial geochemical dataset, a total of six rock chip samples were collected along the skarn-limestone contact at the two outcrops.
Typical calc-silicate skarn alteration minerals observed include garnet, pyroxene, and apple-green epidote, supporting the historical interpretation of an intrusion-related tungsten skarn system. PEC stated that these observations preliminarily confirm that the skarn system typically associated with tungsten mineralization is exposed, accessible, and mappable at the surface. Babarczy noted that, combined with the extensive historical database and well-preserved drill core, these observations provide a clear pathway to developing a modern geological understanding of the project.
The sampling aimed to test the skarn and its adjacent host rocks across the mapped contact zones. The samples have been sent to American Assay Laboratories in Reno, Nevada, for multi-element analysis including tungsten, molybdenum, bismuth, and related indicator elements.
Perpetual stated that its near-term technical plan will focus on: interpreting the rock chip assay results for the six samples (NVS001–NVS006); digitizing and compiling drilling records from over 400 historical drill holes into a modern database; verifying and reconciling historical drill hole collars, surveys, and assay records; cataloging and logging historical diamond drill core stored on-site and within the mine; constructing a modern 3D geological model using structural observations from the field visit, historical sections, and drill hole data; and identifying priority targets for drilling and modern geochemical programs.
