Liberty Gold Intersects High Grade Oxide Gold at the Back Range Zone, Confirming the 7 km Northwest Extent of the Black Pine Gold System
LBP400: 1.01 g/t Au over 29.0 m and 0.87 g/t Au over 18.3 m
VANCOUVER, B.C. – Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (“Liberty Gold” or the “Company”) is pleased to announce results of reverse circulation (“RC”) drilling in the Back Range Zone, which confirm historical results and extend gold mineralization beyond the current Mineral Resource at the Black Pine Oxide Gold Project, southeast Idaho (“Black Pine”). The Back Range Zone was last drilled 30 years ago, and today’s drilling confirms a minimum seven kilometer (“km”) mineralized system in a northwest-southeast direction, which remains open for extension.
The Back Range Zone is located approximately 1 km to the northwest of the Discovery Zone. Mineralization in this area is above average grade and is present at shallow depth, potentially offering early heap leach feed in a production scenario. The current resource for the Back Range, based entirely on historical data, is 17,000 indicated ounces (967,000 tonnes grading 0.56 grams per tonne gold (“g/t Au”) and 43,000 inferred ounces (2,481,000 tonnes grading 0.54 g/t Au) in multiple small resource pits. The Back Range Zone remains open in three directions and additional drilling may merge the small pits into a single, larger resource pit.
The 1 km, undrilled, covered area between the Back Range Zone and the Discovery Zone is highly prospective and has not yet been drill tested. This area will be included in a future exploration permit application. A similar scenario existed in the Rangefront Focus Area prior to drill testing, with results to date pointing to the potential for a large gold deposit in this area.
Cal Everett, President and CEO of Liberty Gold stated, “Our drilling at the Back Range Zone has confirmed that gold mineralization extends beyond the limits of the current resource pits, returning thick sections of high-grade oxide gold mineralization at shallow depths. The Back Range Zone, and the area between Back Range and Discovery Zone, warrant additional drilling in 2022 to continue to expand the now plus 10 square kilometers, drill confirmed mineralized footprint at Black Pine.”

BACK RANGE ZONE DRILLING HIGHLIGHT TABLE1
*Reduced cyanide solubility in this interval.
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.
BACK RANGE KEY POINTS:
- Liberty Gold’s modern drill confirmation of near-surface, oxide gold mineralization in the Back Range Zone, the first drilling in this area in over 30 years, firmly establishes a minimum 7 km northwest-southeast length of the major gold-mineralizing system at the Black Pine deposit.
- The drill results in this release illustrate the presence of high-grade gold outside of the footprint of historical drilling, suggesting that the Back Range deposit may grow with additional drilling, linking to the Discovery Zone and Rangefront Zone.
- Mineralization in the Back Range Zone is shallow and higher-grade than the Black Pine deposit as a whole, offering the potential for early heap leach feed in a future production scenario. It is open to the north, west and east.
- Cover rocks extend between the Back Range Zone and the rest of the Black Pine gold system, but geologic modeling suggests that mineralization extends across this 1 km-long, undrilled gap in gold system.
- In a northeast – southwest direction, ongoing drill results confirm an approximate 4 km width to the gold system orthogonal to the 7 km trend.
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 Zone (D-1, D-2 and D-3 high-grade oxide gold zones) as well as smaller pits at the Rangefront, M, CD Pit, F, J, E Pit and Back Range zones. The Black Pine mineral resource estimate released on July 13, 2021 (see below) does not include any drilling conducted in 2021. Our present focus is on exploring the Rangefront Focus Area, which will see drilling throughout the winter months, with a goal to defining a large gold deposit in this area.
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, 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 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 0.10 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.
