About this update from Lion Rock Resources Inc

Vancouver, British Columbia--(Newsfile Corp. - June 9, 2026) - Lion Rock Resources Inc. (TSXV: ROAR) (FSE: KGB) (OTCQB: LRRIF) ("Lion Rock" or the "Company") is pleased to announce it has commenced a metallurgical and mineralogical testing program at the past-producing Volney critical minerals and gold project in the Black Hills of South Dakota, USA. The program will evaluate concentrate grades, mineral recoveries, and processing pathways for the lithium, tin, and tantalum system at Volney, as the Company continues to rapidly advance the project.Program HighlightsMetallurgical and mineralogical testing underway, targeting the richly mineralized lithium-tin-tantalum-bearing system confirmed during the Company's recent drill programLarge bulk samples (< 200 kg each) will be collected from exposed pegmatite surfaces across the Volney Project, allowing for an expedited and higher quality testing processTesting will evaluate potential concentrate quality and recovery rates for lithium, tin, and tantalumResults will be used to help determine optimal processing pathways for any future production, such as on-site concentration, off-site concentration, and direct shipping of material to end usersVolney has historically produced spodumene concentrate of up to 6.3% Li₂O, tin concentrate of up to 62.5% Sn, and tantalite concentrate of up to 57% Ta₂O₅ (see Historical Production Data below)Test results will additionally be used to prioritize targets for regional drilling planned for this yearDale Ginn, President and CEO of the Company, commented: "As a past-producing critical minerals property, Volney is exceptionally well positioned for rapid development. For many projects, metallurgical testing would take place further along the development timeline, but the nature of mineralization and our existing infrastructure is accelerating our progress. We are not just exploring; we are gathering and analyzing the data to evaluate potential paths for future production."A Past-Producing Asset with Significant Structural AdvantagesVolney has a well-documented production history, most recently under Fansteel Mining Corp. The property benefits from significant infrastructure already in place, including an all-season road, on-site power and water, and a previously used concentrator facility. The project sits on private land less than one hour from the rail network in a pro-minin...
