Lion Rock Resources Reports Results from High-Resolution Magnetic Survey and 3D Inversion at Volney Project, South Dakota

Vancouver, British Columbia--(Newsfile Corp. - August 11, 2025) - Lion Rock Resources Inc. (TSXV: ROAR) (FSE: KGB) (OTCQB: LRRIF) (the "Company") is pleased to announce results from a recent high-resolution UAV magnetic survey ("exMAG") and advanced 3D inversion at the Volney Project. The exMag results enhance Lion Rock's current geological interpretation of a significant gold and LCT pegmatite system across the property (Figure 1). With drill permitting now it its final stages, the Company is preparing to launch its inaugural drill program at Volney, targeting priority areas defined by recent surface sampling and the new magnetic data.

Lion Rock recently announced a successful surface sampling program, identifying a continuous high-grade gold horizon over 260 meters. Rock sampling returned assay values of up to 189.5 g/t Au. Complementary magnetic data reinforce the continuity of the system and indicate strong potential for expansion. The gold-bearing structure remains open in all directions, significantly improving the project's exploration upside.

Survey Highlights

• Structurally Controlled Gold System: Mineralization is most prominent in areas where pegmatite contacts meta-basalt in zones of intense shearing. Magnetic signatures around the Rusty Shaft correlate with previously reported high-grade gold samples (see Lion Rock News Release dated May 28, 2025).

• 3D Inversion Confirms Large Magnetic Anomaly at Depth: The exMAG survey data reveals a large, consistent magnetic high along the shear corridor, supporting the presence of a deep-seated mineralized system spanning over 1 km (Figure 2).

• LCT Pegmatite Correlation: Away from the mineralized shear zone, a more discrete correlation emerges between LCT pegmatite bodies and magnetic lows. The Giant Volney and adjacent pegmatites are overprinted by the mineralized amphibolite, distorting any correlation.

• Structural Mapping and Drill Targeting: The survey identifies key structural breaks and lithological contrasts between gold and pegmatite systems, aiding in both regional and near-known mineralization drill targeting.

Dale Ginn, President and CEO of Lion Rock, stated, "The magnetic survey has revealed a clear contrast between the gold-bearing mafic host rock and LCT pegmatite system. This will assist our team in extrapolating target areas beyond the main known horizon. Our next step is to carry out a detailed exploration plan and take full advantage of this unique and special multi-commodity project. We are particularly excited about the upcoming inaugural drill program, with permitting well underway and drilling anticipated to commence in the coming weeks."

About the Volney Project

The Volney property is a multi-commodity project strategically located in South Dakota's Black Hills, a historically rich and active mining region (Figure 3). The Black Hills have produced over 62 million ounces of gold, including from the prolific Homestake Mine, one of the most significant gold producers in North American history. The Volney Project is home to the Giant Volney pegmatite, a 635 m long LCT (Lithium-Cesium-Tantalum) pegmatite which remains untested at depth. The district continues to attract modern exploration efforts, with companies such as Dakota Gold Corp. actively advancing projects within the Black Hills. The project is accessible year-round and consists of private claims with surface and mineral rights, which facilitates rapid permitting and project advancement.
