LION ROCK’S FIRST RESULTS FROM MAIDEN DRILL PROGRAM REVEALS
DISCOVERY OF MULTIPLE CRITICAL MINERAL INTERCEPTS WITHIN THE
VOLNEY PEGMATITE
Vancouver, British Columbia – February 26, 2026 – Lion Rock Resources Inc. (TSX-V: ROAR, FSE:
KGB, OTCQB: LRRIF) (the “Company”) is pleased to report drill results from the Giant V olney target
area at its V olney Project in the historic Black Hills mining district of South Dakota, USA.
Initial results from the Company’s recently completed Phase 1 drill program have returned significant
lithium-tin-tantalum results (Table 1) along with anomalous critical mineral results. Approximately 3,600
metres of diamond drilling across 15 drillholes has been completed along the V olney trend (Figure 1). Partial
assay results from four drillholes are set out below. The remainder of the assay results on those drillholes
as well as full assay results from the other 11 drillholes, including additional lithium and gold analyses,
remain pending and will be reported as received.
News Highlights
• Significant Lithium Intercepts at Giant Volney at Surface:
Drillholes VOL25-004, VOL25-005 (Figure 2), and VOL25-007 (Figure 3) returned multiple
lithium-bearing pegmatite intersections including:
o 0.8% Li2O over 25.4 m, including 1.3% Li2O over 14.3 m (VOL25-004)
o 1.5% Li2O over 10.3 m, including 2.2% Li2O over 1.3 m (VOL25-005, ended in
pegmatite)
o 1.6% Li2O over 10.6 m, including 2.3% Li2O over 5.7 m (VOL25-007)
• Tin and Tantalum Mineralization Confirmed:
Drilling intersected muscovite-rich pegmatite hosting tin and tantalum mineralization, including:
o 72 ppm Ta over 5.7 m within the lithium interval in VOL25-004
o 120 ppm Ta over 3.0 m within VOL25-005
o 0.1% Sn and 45 ppm Ta over 28.3 m, including 0.3% Sn and 120 ppm Ta over 3.0 m
(VOL25-006)
o 0.1% Sn and 53 ppm Ta over 6.2 m (VOL25-007)
• Multi-Element Critical Mineral Signature Confirmed in Pegmatite:
Initial assay results confirm lithium–tin–tantalum mineralization within pegmatite. Assays also
returned elevated gallium (up to 67 ppm), rubidium (up to 3,948 ppm), cesium (up to 938 ppm),
and tantalum (up to 301 ppm). The multi-element enrichment is consistent with a fractionated and
evolved LCT pegmatite system and supports interpretation of geochemical zonation within the
pegmatite body.
• Collared Directly into Pegmatite; Intersections Represent Partial Thickness Only:
All four drillholes were collared directly into pegmatite. As a result, the reported intervals represent
partial intersections and do not reflect the full interpreted width of the pegmatite body, which
200 Burrard Street, Suite 1615, Vancouver, BC, V6C 3L6
mapping and sampling indicate extends west of the drill collars. Hole VOL25-005 was terminated
early after intersecting historic underground workings and ended in pegmatite.
• Similar Pegmatites Observed More Than 250 m North - Assays Pending:
Additional pegmatite units were intersected more than 250 m north of the Giant V olney area (Figure
4), including near the Rough & Ready target. These pegmatites are mineralogically similar to those
observed in drillholes VOL25-004, VOL25-005, VOL25-006, and VOL25-007. Multiple additional
pegmatite outcrops exhibiting lithium values have been identified on surface across the property
and remain untested by drilling. Assay results for these holes are pending and will be reported as
received.
• Seven Critical Minerals Identified at Volney:
The V olney Project hosts lithium, tin, tantalum, gallium, cesium, rubidium, and gold all of which
are included on the current US Critical Minerals List, underscoring the project’s multi-commodity
critical mineral profile.
Dale Ginn, President and CEO of Lion Rock, stated “These results confirm Giant V olney as a well-
developed, near-surface LCT pegmatite system enriched in lithium, tin, tantalum, and gallium. The
presence of multiple critical metals within a single zoned pegmatite body highlights the broader
strategic relevance of V olney as North America continues to prioritize secure domestic supply chains
for lithium and other critical minerals. Importantly, these results represent only the first batch of assays
from our Phase 1 drill program, with additional lithium and gold results pending from multiple target
areas along the V olney trend. We believe this marks the beginning of a broader evaluation of the district-
scale potential at V olney.”

Quality Assurance / Quality Control (QA/QC)
The QA/QC protocol on the V olney property has been designed to follow industry best practices. Certified
reference material and blank material were inserted at a rate of approximately 4% each. In addition, pulp
and coarse duplicates were collected for appr oximately 10% of samples to assess consistency in
mineralization and laboratory analysis.
All drill core samples were submitted to SGS Laboratories in Denver, Colorado, an independent and
SO/IEC 17025-accredited facility, for sample preparation. Samples were dried at 105°C, crushed to 75%
passing 2mm, riffle split into a representative sample and a 500g course reject, then pulverized to 85%
passing 75 microns. Samples prospective for Lithium mineralization were submitted for 57-element sodium
peroxide fusion ICP-AES/ICP-MS analysis (GE_ICM91A50). Gold prospective samples were analysed
using 30 g fire assay with atomic absorption spectrometry finish (GE_FAA30V5) and 0.25g 33-element
analysis by four-acid digest with an atomic emission spectroscopy finish (GE_ICP40Q12). Analysis was
conducted at SGS Canada’s Burnaby facility.
