en.Wedoany.com Reported - Red Mountain Mining (ASX: RMX) has identified garnet skarn in surface outcrops at the Pioneer Project in Montana, a rock type closely associated with tungsten mineralization in the region. The company has submitted 24 rock chip samples from two prospects for laboratory analysis to assess the economic potential of skarn-type tungsten mineralization, with results expected this month.
The Pioneer Project consists of three claim blocks—Greenstone, Mammoth, and Lost Creek—covering a total area of 209 hectares, located on the eastern edge of the Torre Mountain Batholith. The geological setting of the area is characterized by garnet skarn hosted in limestone, with skarn thickness reaching up to 25 meters, known to contain tungsten mineralization in the form of scheelite. Red Mountain Mining's preliminary field work has confirmed the presence of skarn in outcrops at Mammoth and Greenstone, and 24 rock chip samples have been submitted to the laboratory for testing to determine tungsten content and assess its economic value.
The project is adjacent to land acquired by leading tungsten producer Almonty Industries (ASX: AII) in November last year. Almonty holds the Gentung resource in the area, totaling 6.83 million tonnes at a grade of 0.315% WO3, as well as the historic Ivanhoe and Lost Creek mines, which together produced 680,000 tonnes of tungsten ore. Red Mountain Mining believes the geological conditions of its Pioneer Project are comparable to Almonty's adjacent assets.
The Pioneer claim block contains tungsten-bearing skarn mineralization that was mapped and sampled in the mid-20th century, with historical mining relics still present on site. Additionally, magnetic modeling results indicate subsurface magnetic bodies beneath the Greenstone and Mammoth claim blocks, interpreted as shallow extensions of granodiorite sources within the regional skarn mineralization. Company management noted that the magnetic signature beneath the Gentung resource may extend into Red Mountain Mining's ground, with modeling suggesting that Greenstone and Mammoth may host shallow, limestone-hosted tungsten-bearing garnet skarn beneath surface quartzite.
Red Mountain Mining plans to conduct further surface geological mapping and sampling across all three claim blocks in June. If results from the current rock chip program are positive, the company expects to quickly identify drill targets to explore the subsurface extension of the outcropping skarn. Meanwhile, the company is accelerating environmental and regulatory approval processes, aiming to commence drilling operations during the Northern Hemisphere summer.
