Liberty Gold Corp. (TSX: LGD) (OTCQX: LGDTF) is pleased to announce additional reverse circulation results from the 2021 drill program in the Rangefront Focus Area at the Black Pine oxide gold deposit, Idaho.
The RFA is host to a major new oxide gold discovery in the down-faulted southeast portion of the Black Pine gold system and has been a focus of our drill campaign since it was discovered in Q3 2021. Results to-date confirm the RFA discovery is quickly expanding, with gold mineralization extending over an area of approximately one square kilometer and it remains open for extension in all directions.
Liberty Gold has continued to expand on the D-4 Discovery area within the RFA, adding drill sites to the north, south and east, toward the original Rangefront deposit defined by shallow historical drilling. Notably, a NW-SE-trending, high-grade mineralized core has now been delineated over a 300 x 400-meter (“m”) area that remains open along trend to the NW and SE. Additionally, of the 46 holes drilled and assayed in the RFA since Q3 2021, virtually all have returned multiple, relatively flat zones of oxide gold mineralization from near-surface to a depth of up to 400 m.
Cal Everett, President and CEO of Liberty Gold stated, “RFA drilling continues to deliver significant oxide gold intercepts in multiple zones over a large surface area. With a high-grade core now defined and open for expansion along trend, we expect a significant upgrade to the mineral resource estimate in 2022.”
Moira Smith, VP Exploration and Geoscience for Liberty Gold stated, “The results are so compelling, we have decided to forgo the typical winter drill shut-down and work through the winter with three RC and one core drill focused on the RFA. The geometry and scope of mineralization at Rangefront looks very similar in many ways to the Discovery Zone after only four months of drilling, with several stacked, low-angle zones of structurally and stratigraphically controlled mineralization around a high-grade core. This similarity continues to reinforce our hypothesis that the RFA represents the down-faulted southeast portion of the Black Pine gold system. The current success at the RFA is exciting and there remain several square kilometres of un-drilled prospective ground.”

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 thickness are reported herein; true width varies depending on drill hole dip, but generally range from 60% to 80% of true thickness. Gold grades are reported uncapped.
2022 WORK PROGRAM
The 2022 exploration program at Black Pine commenced at the beginning of January, with three RC and one core rig active. Drilling through to the end of February will focus on the lower-elevation RFA to provide data for resource estimation and metallurgical testing. The current RFA drill campaign will end in late February, and the drillhole database and geological model will be updated for the upcoming mineral resource estimate. The drills will then move off in the interim to continue both in-fill and step-out drilling at other prospective areas on the Black Pine deposit.
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 Q3 2022 and reach a prefeasibility decision by Q4 2022.
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.
