LGD Liberty Gold Corporation

Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (“Liberty Gold” or the “Company”) is pleased to provide a progress update on activities related to process water supply, lands exchange and assessing gold recovery potential from the historic leach pads at its Goldstrike Oxide Gold Project (“Goldstrike”) in southwestern Utah.

HIGHLIGHTS

Process Water Supply

• Liberty Gold has retained Loughlin Associates and LRE Water, both experienced water exploration and evaluation consultant groups in the Great Basin, to design and execute a hydrological evaluation of potential water sources in the region.
• Desktop studies have commenced and field work is anticipated to start in July.
• Water supply requirements for a future mining operation range from 1,000 to 1,200 acre feet per annum (“AFA”); or ~39 to 47 litres per second (“l/s”), with an upper limit of 1,500 AFA (59 l/s).

Potential Land Exchange

• A block of land surrounding the Goldstrike deposit has been included in a proposed land exchange between The US Bureau of Land Management land exchange with the Utah School and Institutional Trust Lands Administration.
• The “Utah School and Institutional Trust Lands Exchange Act of 2023”, Senate Bill 1405, was presented to the US Congress in May and is currently in the committee stage in both the House and the Senate.
• The Company continues to monitor progress of this legislation through the approvals process.

Metallurgical Testwork

• Metallurgical studies at Goldstrike are testing the amenability of heap leaching the historically mined materials thus potentially providing an opportunity to process this early in a future heap leach mining operation, increasing mine life, and improving the project economics.
• Sonic drilling in the Hamburg/Main/Hassayampa area generated four composites of previously leached oxide ore from the two historic leach pads (“Leach Pads”), two composites of pad backfill (material underlying the Leach Pads, filling previously mined open pits) and two composites of waste rock materials.
• Metallurgical column leach testing was completed with key results including:
  • Leach Pad Material
    • Weighted average gold extraction1 from column leach tests:
      • Leach Pad 1 (run-of-mine) 62.0%
      • Leach Pad 2 (-4 inch crush/agglomerate) 39.5%
  • Backfill (material underlying the Leach Pads):
    • Pad Backfill - High Grade 70.5%
    • Pad Backfill - Low Grade 81.7%
  • Waste Rock Material
    • Main Dump 91.2%
    • Hamburg North Dump 71.7%
• Historic production records2 report that ~7.25 million tonnes (“Mt”) of oxide gold ore at an average grade of ~1.2 grams per tonne gold (“g/t Au”) was leached on the two pads during prior mining operations (1988 to 1994). Based on historic recoveries this indicates that there may be up to 70,000 ounces of gold remaining in the now closed and remediated historic heaps. Test results herein indicate that a portion of this gold could be amenable to extraction using conventional heap leaching.
• Leach Pads 1 & 2 and the underlying backfill are located directly over the Main/Hassayampa/Hamburg oxide gold resource and would need to be stripped in a potential future open pit mining operation to access the underlying oxide gold resource.

Jason Attew, President and CEO for Liberty Gold said, “Since announcing the results of the Sonic drill program last August, we have made significant progress at our Goldstrike Project. Recent metallurgical test results indicate that the historically mined ore, which contains residual oxide gold, performs well under conventional oxide heap leach conditions. These materials could potentially add significant early value to a future leach operation at Goldstrike. As we bring key activities on water, land and metallurgical testwork to a close over the second half of 2023, we expect to position the project favourably for a decision on the next phase of development.”

METALLURGICAL TEST RESULTS – PHASE 3A

Historic Leach Pad Material (Column Leach Test Results)

• Results of metallurgical column testing at Goldstrike on leach pad material (>0.20 g/t Au) produced a column leach weighted average gold extraction of 49.3%, at an average gold grade of 0.58 g/t Au.
• Gold extraction was rapid, with >80% of the leachable gold extracted within the first 10 days.
• Reagent consumptions were low at 0.33 kilogram/tonne (“kg/t”) CN & 0.50 kg/t lime.
• Cement consumption was high and averaged 5.5 kg/t.
• Mineralized material (>0.20 g/t Au) tested came from a total of 348 metres (“m”) of sonic drilling in 21 sonic drill holes from Leach Pads “1” & “2” (see Figures 1 & 2).
• Based on historic records, the heaps were not adequately leached due to poor irrigation practices.
• Pad 1 was a run-of-mine heap, whereas Pad 2 was a -4” crush/agglomerate heap.
• Significant gold grades encountered in the sonic drilling (see press release dated August 9, 2022) suggest incomplete gold leaching occurred throughout the historic heaps and the results herein indicate that the residual gold remains readily soluble under heap leach conditions.
• Sonic drilling on the historic leach pads provided sufficient drill hole assay coverage to allow the potential inclusion of this material in a future mineral resource estimate.
• Testing is underway to characterize historic Leach Pad material crushed and screened at +12.5 millimeters (“mm”). It is anticipated that the +12.5 mm material could be used for new pad overliner and gravel drains, adding early ounces to the production profile.

Backfill Material

• Results of Phase 3A metallurgical column testing at Goldstrike on pits backfill material, underlying the Leach Pads produced are shown in Table 1.
• Leach kinetics are similar to in-situ material tested.
• Sonic Drill testing of the backfill material ranged from 5 to 26 meters below the historic pad and averaged 10 meters in thickness. Current drill density suggests that the oxide gold mineralization is widely distributed above resource cut-off grades.

Waste Rock Material

• Results of Phase 3A metallurgical column testing at Goldstrike on historic surficial waste rock from the Main and Hamburg North areas are shown in Table 1.
• Drill testing of this material indicates oxide gold mineralization is widely distributed above resource cut-off grades.

METALLURGICAL TEST PROGRAM

The metallurgical evaluation of the Goldstrike oxide gold mineralization consists of multiple phases of testwork including:

• Variability composite column tests from PQ drill core:
  • Phase 13 (20 composites):
    • 85.9% weighted average gold extraction, ranging from 55.0 to 97.0%
  • Phase 24 (29 composites):
    • 84.2% weighted average gold extraction, ranging from 46.4 to 95.0%
  • Phase 3A (8 composites)
    • Results released herein.
  • Phase 3C (22 composites)
    • Taken from PQ drill core drilled in 2022, these composites are currently in preparation for column testing. Infill drill holes cover Hamburg, Basin and Padre areas.
• Bulk Samples
  • Phase 3B
    • Comprising 11, 300-1,000 kilogram, bulk samples taken from outcropping oxide gold mineralisation is under leach in the lab with final results expected in early Q3.

Composites for all phases of test work were selected through consideration of alteration and gold grade and gold cyanide solubility to achieve a range of geo-metallurgical types. Composites were assembled in Elko, Nevada by Liberty Gold staff, utilizing one-half or three-quarter sawed PQ core or sonic samples, then shipped to Kappes, Cassiday and Associates in Reno, Nevada for metallurgical testing, comprising bottle rolls, column testing and geo-metallurgical characterization, including gold and silver assays, cyanide solubility, sulphur and carbon speciation, preg-robbing analysis, ICP geochemical assays, whole rock analysis, QXRD, load-permeability tests, modified SMC comminution testing, Bond Abrasion (Ai) testing and environmental chemistry.

All metallurgical work at Goldstrike has been supervised by Gary Simmons MMSA, formerly the Director of Metallurgy and Technology for Newmont Mining Corp. Mr. Simmons has managed or supervised many metallurgical testing programs on similar Carlin-style sedimentary rock-hosted oxide gold deposits throughout the Great Basin.

Metallurgical test work to be completed by year end on Goldstrike is anticipated to exceed pre-feasibility requirements. It is anticipated that one further phase of testwork is required to meet feasibility standards on current resources. Results continue to support a technically simple, low initial capital, low operating cost, combination of crush/agglomeration and ROM heap leach processing routes for oxide mineralization.

QUALITY ASSURANCE – QUALITY CONTROL

Drill composites were calculated using a cut-off of 0.10 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. Selected holes are also analyzed for a 51 multi-element geochemical suite by ICP-MS. ALS Geochemistry-Reno is ISO 17025:2005 Accredited, with the Elko and Twin Falls prep lab listed on the scope of accreditation.
