Lion Rock Resources Reports New Gold Results Including 189.5 g/t at Volney Project, South Dakota

Vancouver, British Columbia--(Newsfile Corp. - May 28, 2025) - Lion Rock Resources Inc. (TSXV: ROAR) (FSE: KGB) (OTC Pink: LRRIF) (the "Company") is pleased to announce gold assay results from its recent surface sampling program at the Volney Project, South Dakota. The results include 189.5 g/t Au from float material and 14.0 g/t Au from bedrock, confirming the presence of multiple distinct gold target zones and strong potential for further discoveries across underexplored areas of the property. Located 20 km southwest of Spearfish in the prolific Black Hills Mining District, Volney is a past-producing, multi-commodity project hosting high-grade gold, lithium, and tin.

News Highlights

• High-Grade Bedrock Mineralization Along Major Gold-Bearing Horizon: Sampling at the Volney Project target outlined a 260 m shear trend open along strike, with bedrock chip samples returning up to 14.0 g/t Au (Figure 1). A total of 20 bedrock samples returned values over 0.5 g/t Au, associated with quartz veining or sheared greenstone units (Table 1).

• High-Grade Float Samples: Grab samples from float material returned 41 samples >1.0 g/t Au, including 7 samples >10.0 g/t Au, with the highest at 189.5 g/t Au (Table 2). High-grade samples were typically associated with quartz veining and silicification.

• Multiple Gold Mineralization Host Units: Gold occurs in both greenstone-hosted and Tertiary vein and breccia systems. Only a limited portion of the property has been explored to date, indicating strong potential for additional discoveries.

• Multi-Commodity Upside: In addition to high-grade gold, recent grab sampling returned lithium values up to 5.3% Li₂O from historic stockpiles and up to 3.7% Li₂O from outcrop. 13 stockpile samples also reported tin values greater than 1.0% Sn, highlighting by-product potential (see Lion Rock News Release dated May 13, 2025).

• Private Land - Fast-Tracked Permitting: The Volney Project is situated on 142 hectares of privately held land with surface and mineral rights, enabling rapid drill program execution and accelerated permitting from exploration through production.

Dale Ginn, President and CEO of Lion Rock, stated, "These results underscore the exceptional potential of the Volney Project. We're seeing strong gold grades across multiple zones which confirm the presence of high-grade mineralization at surface. Combined with promising lithium and tin values and the advantage of private land ownership, Volney represents a truly unique and exploration opportunity for Lion Rock."

Grab and chip samples are selective in nature and may not be representative of the mineralization on the property. For grab samples, 1 to 3 kg of material was collected from a single location marked as either float or stockpile. For chip samples, 1 to 3 kg of rock was collected by hammer and chisel from outcrop faces over up to 1 m.

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 2). 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.

QA/QC

Samples were collected by Lion Rock personnel and were crushed, pulverized and pulps prepared by Bond Mineral Services, LLC, an ISO-certified preparatory laboratory located in Central City, South Dakota. Sample pulps were analyzed by ALS Geochemistry in Reno, NV, a laboratory accredited in accordance with the standards of ISO 17025:2017. Sample pulps were analyzed using industry standard analytical package ME-MS89L. Internal laboratory QA/QC was relied upon for the purposes of this sampling campaign.
