Lion Rock Starts Metallurgical Testing at Volney Project in South Dakota
Lion Rock Resources has commenced metallurgical testing at the past-producing Volney critical minerals and gold project in South Dakota, targeting lithium, tin, and tantalum recoveries.

Lion Rock Resources Inc. has announced the start of metallurgical and mineralogical testing at its Volney critical minerals and gold project in the Black Hills of South Dakota. The program aims to evaluate concentrate grades, mineral recoveries, and processing pathways for the lithium, tin, and tantalum system at the past-producing site. This testing is a crucial step in de-risking the project and determining the most efficient methods to extract these valuable metals, which are essential for modern technologies like batteries and electronics.
The testing program is a key step in advancing the Volney project, which historically produced gold and now shows potential for critical minerals. For precious metals traders, the development highlights the growing intersection between gold mining and critical mineral supply chains. While gold remains the primary focus for many investors, projects like Volney that offer by-product or co-product critical minerals could provide additional revenue streams and strategic value. This is particularly relevant as central banks globally have been increasing their gold reserves since 2022, seeking to diversify away from dollar-denominated assets amid geopolitical tensions. The real US 10-year yield, which inversely correlates with gold prices, remains a key driver for the metal's investment demand. Additionally, the spread between COMEX futures and LBMA spot prices can signal physical market tightness, while ETF flows into funds like GLD and IAU reflect retail and institutional sentiment. Jewelry demand, especially in India and China, also supports gold prices, but investment demand is more sensitive to macroeconomic shifts. The US Dollar Index (DXY) typically moves inversely to gold, and a weaker dollar could further boost gold's appeal.

Investors should watch for assay results and metallurgical recoveries from the testing program, which will inform future feasibility studies. The company's ability to efficiently process lithium, tin, and tantalum could significantly enhance project economics. Further updates are expected as Lion Rock continues to rapidly advance the project. Positive results could attract strategic partnerships or offtake agreements, especially given the US government's focus on securing domestic critical mineral supplies.
