Liberty Gold Corp. (TSX: LGD) (OTCQX: LGDTF) is pleased to announce results from the 2022 winter reverse circulation drill program at the M Zone, and final results from the 2021 resource upgrade and step-out drilling program at the Discovery Zone at the Black Pine oxide gold deposit in southern Idaho.
The M Zone, located east of Discovery Zone, is a focus of our 2022 drill program given the near-surface mineralization and proximity to lower elevation areas to the east that might be suitable for heap leach infrastructure. Results from the 2022 winter drill program delivered relatively high-grade oxide gold mineralization at shallow depths (~30 to 80 meters below surface). The current resource contains two pits in the M Zone and today’s results targeted the 250 m gap between these two pits, with the primary objective to link mineralization into a single larger deposit over a 750 m length.
Drilling is currently underway to the southwest of the M Zone, testing a 650 m gap in bedrock drilling overlain by a historic waste dump that potentially contains mineralization between the historic Tallman and CD pits, with the goal of linking mineralization within this entire corridor from M Zone to CD Zone, a distance of over 2 kilometres.
At the Discovery Zone, infill drill results continue to confirm and increase confidence in the broad continuity of oxide gold mineralization across the Discovery Zone, which hosts 74% of the current Black Pine resource ounces. Step-out drilling in areas surrounding the Discovery Zone, suggests that several of these zones can potentially be merged into a single, contiguous resource area ultimately linking to the main Discovery Zone pit.
Liberty Gold continues to advance its 87,000 m drill program in 2022 and has delivered strong early returns at both Rangefront and now at the M Zone. This illustrates the success this year’s program has had so far in discovering, linking up and expanding mineralized areas across the entire deposit and will continue to be a key focus of our exploration program this year.
Cal Everett, President and CEO of Liberty Gold stated, “The 2021 drill campaign continued to deliver strong results further demonstrating Black Pine as a large-scale gold deposit in the Great Basin. The notable 2021 success was the Rangefront discovery, but step-out and in-fill results within the Discovery Zone and surrounding areas also continue to add value to the deposit. By the end of 2022 Liberty Gold will have completed approximately 150,000 additional metres of drilling subsequent to our first resource estimate at Black Pine.”

1Liberty Gold has changed the reporting cut-offs to include a 0.15 g/t Au cut-off, to reflect the lower cut-offs used by most operating oxide heap-leach mines in the Great Basin. The 0.15 g/t Au cut off is not shown in the table if it is identical to the corresponding interval using a 0.2 g/t Au cut-off. Downhole thicknesses are reported herein; true width varies depending on drill hole dip, but generally ranges from 60% to 80% of true thickness. Gold grades are reported uncapped Some deep intervals in this area report reduced cyanide solubility resulting from the presence of organic carbon.

2022 WORK PROGRAM
The 2022 exploration program at Black Pine commenced in January, with three RC and one core rig active. Drilling through to the end of February focused on the lower-elevation RFA and M Zone with the goal to continue resource expansion and confirmation, with the core drill focused on metallurgical testing. On March 1, two drills were moved to Goldstrike to commence engineering, resource upgrade and metallurgical drilling, while two drills remain at Black Pine to focus on step-out drilling and new target testing.
Liberty Gold plans to aggressively advance Black Pine in 2022 with drilling, initial engineering and permitting programs and further de-risking activities, with the goal to provide an updated resource estimate and Preliminary Economic Assessment in the second half of 2022, subject to exploration success.
ABOUT BLACK PINE
Black Pine is located in the northern Great Basin, immediately adjacent to the Utah/Idaho border. It is a Carlin-style gold system, similar in many ways to the prolific deposits located along Nevada’s Carlin trend. Like Nevada Gold Mines’ Long Canyon deposit, Black Pine represents a growing number of Carlin-style gold systems located off the main Carlin and Cortez trends in underexplored parts of the Great Basin. The historic Black Pine Mine operated from 1992 to 1997, during a period of historically low gold prices, with 435,000 ounces of gold produced from five composite, shallow pits, with an average head grade of 0.63 g/t Au.
A mineral resource estimate containing an indicated mineral resource of 1,715,000 ounces of gold at an average grade of 0.51 g/t Au and totalling 105,075,000 tonnes; and an inferred mineral resource of 370,000 ounces of gold at an average grade of 0.37 g/t Au and totalling 31,211,000 tonnes was released on July 13, 2021, with the resource technical report filed on SEDAR on August 19, 2021, and available on the Liberty Gold website.
A virtual site tour and 3D model of Black Pine property, including details about the geology and mineralization, is available on the homepage of the Company’s website: libertygold.ca
QUALITY ASSURANCE – QUALITY CONTROL
Drill composites were calculated using cut-offs of 0.15 g/t Au, 0.20 g/t Au, 1.0 g/t Au and 5.0 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 60% to 80% 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 ppm 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 prep lab listed on the scope of accreditation.

ABOUT LIBERTY GOLD
Liberty Gold is focused on exploring the Great Basin of the United States, home to large-scale gold projects that are ideal for open-pit mining. This region is one of the most prolific gold-producing regions in the world and stretches across Nevada and into Idaho and Utah. We know the Great Basin and are driven to discover and advance big gold deposits that can be mined profitably in open-pit scenarios. Our flagship projects are Black Pine in Idaho and Goldstrike in Utah, both past- producing open-pit mines, where previous operators only scratched the surface.
