High-grade gold and lithium with historic tin in South Dakota’s Black Hills
Shear-hosted gold mineralization occurs alongside Lithium-Tantalum-Tin (LCT) pegmatites, providing multiple, independent exploration targets within a single project footprint.
Multiple LCT pegmatites converge to form the Giant Volney Pegmatite, extending approximately 635 metres at surface. Surface sampling returned average grades of 4.4 percent Li₂O, with values up to 5.4 percent Li₂O.
Lion Rock has recently completed a drill program at the Volney Project, reflecting an active, funded exploration effort focused on systematically advancing both gold and lithium targets.
Historic workings at the Rusty Mine reported gold intersections of 5 to 15 g/t Au over widths of 15 to 45 metres. Channel sampling at the Rough and Ready Mine returned 18.2 g/t Au over 18.3 metres.
Historic drilling at the Rusty Mine was limited to approximately 50 metres depth, yet intersected wide mineralized zones in all eight drill holes, indicating limited testing of the system at depth.
Gold, lithium, and tin in a historic mining district
The Volney Project is located in the Black Hills of South Dakota, a region with a long history of gold and tin production and limited modern exploration. The property hosts multiple historic mines and workings, including the Rusty Mine and Hydliff Adit for gold, and the Rough and Ready Mine for tin and gold.
Gold mineralization at Volney is interpreted to be shear-hosted, with wide zones of mineralization identified in historic surface and underground workings. Lithium mineralization is hosted within Lithium-Tantalum-Tin pegmatites, including the Giant Volney Pegmatite, which represents a key focus of the project’s hard-rock lithium exploration.
Historic exploration across the property was shallow and discontinuous, leaving the system largely untested at depth and along strike.
Modern drilling in an underexplored system
Historic drilling at Volney was limited to shallow depths, generally less than 50 metres, yet consistently intersected mineralization. This provides a strong technical rationale for modern drilling to evaluate depth extensions, structural continuity, and additional pegmatite targets across the property.
Tin-rich zones near the Rough and Ready Mine, where high-grade cassiterite production occurred in the early 20th century, further support the fertility of the LCT pegmatite system and provide additional exploration vectors.
Lion Rock is advancing the Volney Project using a disciplined, technically driven approach designed to systematically evaluate both gold and lithium mineralization.
