Liberty Gold Corp. (TSX: LGD) (OTCQX: LGDTF) is pleased to announce the new D-4 gold discovery at the Rangefront target on its Black Pine Oxide Gold deposit in southeastern Idaho, confirmed with the release of the first tranche of 2021 Reverse Circulation drill results.
D-4 discovery drill holes LBP356 and LBP358 were drilled from the first site established in the new permit area targeting a 1,250 metre gap in drilling along the four kilometre long dominant mineralization trend at Black Pine. This large gap between two mineralized areas had seen no previous drilling due to the presence of shallow sandstone cover rocks that overlie the gold-host carbonate rocks. The two +100 gram-metre oxide gold intercepts are spaced approximately 100 m apart and are characteristic of other high grade oxide gold zones across the property.
Cal Everett, President and CEO of Liberty Gold stated, “D-4 at Rangefront represents another game-changing discovery for Black Pine in a completely untested area of the property. With mineralization in the Discovery Zone trending southeast under sandstone cover, we believed the Rangefront area had potential to host the faulted-off, southern extension of the Black Pine gold system. While it is still early days, with the high-grade intervals in LBP356 and LBP358 and mineralization over a 400 m down-hole interval in LBP349, we have proof of concept that significant gold mineralization exists in the D-4 area. We are now aggressively drilling at D-4 and expect to continue through the remainder of the 2021 drill season. The D-4 discovery, along with new frontier discoveries at Rangefront Southwest and Upper F Zone also released today, continues to demonstrate the large-scale and robust nature of the oxide gold system at Black Pine, which remains relatively untested after only two years of concentrated drilling in the Discovery Zone.”

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 cut-off. Downhole thickness is 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.

2021 WORK PROGRAM
Drilling commenced April 1st and is focused on upgrading inferred portions of the resource to indicated, step-out drilling on defined targets and discovery drilling throughout the 12 km2 permitted drill area. The initial resource pit encompasses the Discovery Focus Area (D-1, D-2 and D-3 high-grade oxide gold zones) as well as smaller pits at the Rangefront, M, C-D Pit, F, J, E Pit and Back Range zones. The updated Black Pine Oxide Mineral Resource estimate released on July 13 (see below) does not include any drilling conducted in 2021. All zones remain open for extension, with the current drill program focussed on:
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 Newmont’s 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, at an average grade of 0.63 g/t Au.
A 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, with the resource technical report filed on SEDAR and available on the Liberty Gold website on August 19, 2021.
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 a cut-off of 0.20 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 0.200 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.
