LION ROCK RESOURCES REPORTS HIGH-GRADE LITHIUM RESULTS AT
VOLNEY PROJECT, SOUTH DAKOTA
Vancouver, British Columbia – May 13, 2025 – Lion Rock Resources Inc. (TSX-V: ROAR), (FSE:
KGB, OTCPK: LRRIF) (the “Company ”) is pleased to announce lithium assay results fro m its recent
surface sampling program at the Volney Project, South Dakota. The results include values up to 5.3% Li2O
from stockpile material and 3.7% Li2O in pegmatite outcrops and extend the lithium-beari ng pegmatite
trend to 1,000 m by 500 m. Located 20 km southwest of Spearfish in the Black Hills Mining District, V olney
is a past-producing, multi-commodity project that h osts high-grade gold, high-grade lithium, and high-
grade tin.
News Highlights
• High-Grade LCT Pegmatites in Outcrop – Significant Expansion Potential: A total of 26
outcrop samples returned values exceeding 1.0% Li 2O, confirming multiple high-grade lithium-
bearing pegmatites at surface across a 1,000 m by 5 00 m corridor, that remains open in all
directions. Importantly, newly sampled outcrops loc ated 600 m from the historic Giant Volney
pegmatite returned values up to 3.7% Li 2O, underscoring the broader potential for high-grad e
lithium mineralization beyond historically known zo nes and highlighting the opportunity to
significantly expand the mineralized footprint.
• Validation of Historic High-Grade Material: A total of 43 stockpile and mill waste samples
returning values above 1.0% Li 2O and up to 5.3% Li 2O. In the historic Giant Volney pit area, 26
stockpile samples yielded an average grade of 3.8% Li 2O, confirming high-grade lithium values
reported in historic bulk sampling.
• High-Grade Multi-Commodity Potential Includes High-Grade Gold and Tin: In addition to
lithium, a total of 13 stockpile and mill waste sam ples returned tin (Sn) values above 1.0% Sn,
indicating significant potential for by-product recovery. The property is also host to high-grade gold
mineralization with historic grades up to 8.0 g/t Au over 43.0 m and 18.2 g/t Au over 18.3 m .
• 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 strong lithium results confirm the high-grade
potential of the Volney Project. The combination of high-grade outcrop samples and historically mined
material presents an exciting opportunity for continued exploration, both at surface and through drilling.
With 142 hectares of private land, we’re able to fa st-track permitting and quickly advance toward dril l
testing. We’re also highly encouraged by the multi-commodity potential of the system, which also includes
high-grade gold and tin, and we look forward to exp anding the known pegmatite extents through our
upcoming exploration program .”

Lithium Surface Sampling
An initial surface sampling campaign at the V olney Project successfully returned strong lithium values ,
with 69 out of 100 samples assaying above 1.0% Li 2O. The program included sampling of mill waste,
stockpiles, and pegmatite outcrops ( Table 1 ), targeting both historically known and newly mapp ed
pegmatites. Outcrop sampling covered more than twen ty previously unsampled pegmatite and confirmed
anomalous lithium mineralization across a broad area measuring approximately 1,000 m by 500 m ( Figure
1). The highest lithium value from outcrop was 3.7% Li2O, returned from a previously untested pegmatite
located over 600 m from the historic Giant Volney pegmatite.
The lithium-bearing pegmatites observed were composed of quartz-oligoclase and typically hosted visible
accessory minerals including spodumene, amblygonite , cassiterite, and tantalite. Exposed pegmatite
outcrops ranged in width from 10 to 30 m.

Stockpile sampling also produced encouraging results, with grades up to 5.3% Li2O. A total of 26 stockpile
samples collected from the historic Giant Volney pit area averaged 3.8% Li2O, supporting the presence of
high-grade lithium in historically mined material. Several stockpile and mill waste samples also retur ned
significant tin values, indicating potential for mu lti-commodity recovery. Further work is warranted t o
locate the bedrock source of the tin anomalies.
In addition, tin mill tailings contained notable lithium values up to 0.8% Li 2O, while three samples from a
remaining ore bin at the historical tin mine return ed between 1.2% and 1.6% Li 2O. These results confirm
that the historically mined Rough & Ready pegmatite units were also lithium-bearing.
Complete assay results for outcrop samples exceedin g 1.0% Li 2O and stockpile samples over 3.0% Li 2O
are presented in Tables 2 and 3, respectively.
