Liberty Gold Confirms Gold Recovery Opportunity in the Legacy Heap
at the Black Pine Oxide Gold Project, Idaho
Unlocks Potential for Resource and Reserve Expansion
VANCOUVER, B.C. – Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (“Liberty Gold” or the
“Company”) is pleased to report the results of the recently completed sonic drilling program on the
legacy heap leach pad ( “L-HLP”) at its flagship Black Pine Oxide Gold Project (“Black Pine”) in
southeastern Idaho.
Drill hole assays confirm the presence of residual , cyanide-soluble gold in the legacy heap ,
consistent with internal expectations. This highlights a dual opportunity to recover additional gold
ounces, while re-purposing the legacy material for use in the construction of the new heap leach
pad (“N-HLP”) at Black Pine.
The relocation of the legacy heap would also improve the Rangefront open pit design, which for
the Preliminary Feasibility Study (“PFS”) included a 50-meter (“m”) setback from the toe of the L-
HLP. Removing this setback limit may provide mining access to an estimated ~250,000 ounces of
oxide gold mineralization currently defined as resource, on the northern margin of the Rangefront
deposit. Furthermore, relocation of the L-HLP would generate an important near-pit exploration
opportunity, where historic drilling results suggest oxide gold mineralization continues beneath
the legacy heap. A resource estimate for the L-HLP is underway and samples are being prepared
for metallurgical testing as part of the feasibility program.
See https://vrify.com/decks/19714 for a dynamic 3D view of sonic drill results and implications
for significant value unlock.
Highlights:
• The 24-hole, 1,400 m sonic drilling program was completed across the ~31 million tonne
legacy heap.
• Assay results indicate residual gold grades supportive of potential economic reprocessing,
with individual samples ranging 0.06 to 1.18 grams per tonne (“g/t”) gold (“Au”) with the
highest grades occurring near the surface.
• Potential for reducing construction capital by reuse of the legacy heap material, located
close to the site of the N-HLP, as over-liner.
• The relocation of th is material provides an important opportunity for near-pit Resource
and Reserve growth at the Rangefront deposit.

Jon Gilligan, President and CEO, stated: “The results confirm the opportunity to turn a legacy mining
feature into a strategic win for Liberty Gold and the Black Pine Project. Whilst the gold grades are
naturally low due to previous processing, it appears there is sufficient recoverable gold to cover the costs
of rehandling and reprocessing , which makes this a strong value proposition as we move the heap to
unlock the resource and reserve potential below. Whether through incremental gold recovery, reduction
in initial capital costs, expansion of our Resource potential, or the continuation of our cooperative
agency relationships, this work exemplifies our commitment to responsible development and value
creation.”
Next Steps
1. Resource Estimation: preliminary work is underway for the L-HLP.
2. Testwork: Metallurgical testing is underway to assess leach -recoverable gold from the L-
HLP and access the material’s geotechnical suitability to act as an over-liner replacement.
3. Mine Planning: Once the metallurgical test work is completed, and if it confirms expected
leach characteristics, the Rangefront open pit optimization will be updated to remove the
50 m setback. Mine plans will be run for the L-HLP itself looking at a variety of mining and
processing rates, costs and production. The objective will be to incorporate L-HLP material
into overall feasibility production schedule to potentially add additional ounces into the
reserves.
4. Permitting: Continuation of discussions with relevant State & Federal agencies regarding
both the ongoing L-HLP evaluation and the potential to relocate and incorporate L-HLP
material as part of the N-HLP for residual processing, and ultimately reclamation and
closure following cessation of mining.

QUALITY ASSURANCE – QUALITY CONTROL
Drill composites were calculated using a cut -off of 0.15 g/t Au. Drill intersections are reported as drilled thicknesses. True widths of the
mineralized intervals vary between 30% and 100% of the reported lengths due to varying drill hole orientations but are typically in the range of
50% to 90% of true width. Drill samples were assayed by ALS Limited in Reno, Nevada for gold by Fire Assay of a 30 gram (1 assay ton) charge
with an AA finish, or if over 5.0 g/t Au were re-assayed and completed with a gravimetric finish. For these samples, the gravimetric data were
utilized in calculating gold intersections. For any samples assaying over 0.10 parts per million an additional cyanide leach analysis is done where
the sample is treated with a 0.25% NaCN solution and rolled for an hour. An aliquot of the final leach solution is then centrifuged and analyzed
by Atomic Absorption Spectroscopy. QA/QC for all drill samples consists of the insertion and continual monitoring of numerous standards and
blanks into the sample stream, and the collection of duplicate samples at random intervals within each batch. All holes are also analyzed for a

listed on the scope of accreditation.

Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources
The information, including any information incorporated by reference, and disclosure documents of Liberty Gold that are filed with Canadian
securities regulatory authorities concerning mineral properties have been prepared in accordance with the requirements of sec urities laws in
effect in Canada, which differ from the requirements of United States securities laws.
Without limiting the foregoing, these documents use the terms “measured resources”, “indicated resources”, “inferred resources” and “mineral
reserves”. These terms are Canadian mining terms as defined in, and required to be disclosed in accordance with, NI 43-101, which references
the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards, adopted by the
CIM Council, as amended. However, these standards differ significantly from the mineral property disclosure requirements of the United States
Securities and Exchange Commission (the “SEC”) in Regulation S -K S u b p a rt 1 300 ( th e “SE C M od er ni z a ti o n R u les ”) u nd er th e U ni t ed S t a t e s
