Liberty Gold Corp. (TSX:LGD) is pleased to announce additional reverse circulation drill results from the 2020 regional drill program at its Carlin-style Black Pine oxide gold property (“Black Pine”) in southern Idaho, USA. Regional target drill results confirm the district scale of the Black Pine mineralized system.
Results have been received from the F, Rangefront, J and M zones and Southwest Extension Target, with additional drill holes pending. A total of eight regional drill targets were tested in 2020, with oxide gold encountered in all locations.
During the same time frame, Liberty Gold continued to infill and step out drill in the now-amalgamated D-1, D-2 and D-3 zones in preparation for a maiden resource estimate anticipated for release in late Q1, 2021. The D-1, D-2 and D-3 zones (collectively, the “Discovery Focus Area”) underlie an area of approximately 1.6 square kilometres.

The map shows the Discovery Focus Area, and its spatial relationship to the drill-confirmed regional gold zones and targets in this release. The M Zone is located 1,000 metres east, J Zone 300 m north, F Zone 500 m southwest, Rangefront Zone 2000 m south and Southwest Extension Target 1,500 m southwest of the Discovery Focus Area.
“In addition to our well-established D-1, D-2 and D-3 zones, our drill program continues to demonstrate the widespread nature of gold mineralization surrounding the Black Pine Discovery Focus Area,” commented Cal Everett, President and CEO of Liberty Gold. “We look forward to the release of our Maiden Resource Estimate at Black Pine near the end of Q1 and expect that these regional zones will contribute to it. With a larger drilling program planned for 2021, we hope to expand these regional zones and identify additional areas of mineralization. After receipt of the Maiden Resource Estimate, we plan to advance the property to a Preliminary Economic Assessment.”
F ZONE
As presently understood, the F Zone forms a linear zone of shallow, oxidized gold mineralization that extends north-northwest from the north end of the historic CD Pit, parallel on a regional scale to the D-1 Zone. Mineralization is hosted in calcareous and sandy siltstone assigned to the same stratigraphic unit that hosts the D-3 Zone. Earlier in 2020, drill hole LBP149 encountered 22.9 m grading 2.21 grams per tonne (“g/t”) oxide gold at shallow depth. An additional three holes were drilled from the site of LBP149, as detailed below. In conjunction with historic drilling in the area, the F Zone presently covers an area of approximately 220 m x 100 m. Widely-spaced, shallow, historical, gold-bearing drill holes extend north-northwestward an additional 600 m along trend. The F Zone and its potential northwest extension is a priority infill and extension drill target in 2021.

RANGEFRONT ZONE
Assay results were received from one drill hole in the Rangefront Zone, with results from an additional two holes pending. Approximately 30 historical shallow RC holes test this target, as well as PQ core hole LBP093C, drilled in 2019, that returned 0.49 g/t Au over 55.3 m starting at a depth of 46.2 m. The Rangefront Zone presently measures approximately 500 x 250 m, elongate in a north-south direction, is shallow and thoroughly oxidized, easily accessible at the base of the Black Pine Range, and is open in all directions.
LBP248 was drilled in a west-southwest orientation from the same site as vertical hole LB093C, infilling a 92 m gap between two historical holes.
The Rangefront Zone, as well as the 2 kilometre (“km”) wide, undrilled gap between it and the historical Tallman and CD pits to the northwest and west, respectively, is expected to be a central focus of exploratory drilling in 2021.
RANGEFRONT ZONE HIGHLIGHTS INCLUDE:
Hole ID (Az, Dip) (degrees) | From (m) | To (m) | Intercept (m) | Au (g/t) | Au Cut-Off | Hole Length (m) | Target |

KEY POINTS
J ZONE
The J Zone measures approximately 350 x 200 m, elongate to the northeast. The target has been tested with over 40 shallow drill holes by historic operators, but it is still open in several directions. Liberty Gold tested the J Zone in 2017 with drill holes LBP004 and LBP005. Three additional holes were drilled to test for mineralization in the valley bottom along the southwestern edge of the J Zone, the location of a suspected mineralized structure that may extend southeast toward the eastern edge of the historic A Pit and D-2 Zone. All three holes intercepted significant thicknesses of gold mineralization. Additional drilling is planned in the 250 m-long untested area between LBP224 and the historic A Pit, possibly merging this zone with the D-2 Zone.

2Both the M Zone and J Zone drill holes contain relatively deep intervals with reduced cyanide solubility. The cause of the reduced cyanide solubility is under investigation, but likely reflects the presence of organic carbon. While some of this material will be excluded from any future resource estimate of oxide gold relying on a low cut-off grade derived from an assumption of gold recovery by heap leaching, it may be amenable to extraction of gold by other methods.
KEY POINTS:
M ZONE
The M Zone is an area of shallow gold mineralization located along the range front approximately one km to the northeast of the historic Tallman Pit. The zone, as tested by 10 historic drill holes, including 1.70 g/t Au over 15.2 m in 93BX-82, and 1.33 g/t Au over 10.7 m and 0.98 g/t Au over 10.7 m in 93BX-36. As presently defined, the M Zone measures approximately 250 x 80 m, elongate in a northeast-southwest direction. Two holes were drilled in the northeast end of the zone, with results summarized below. Assays from an additional two holes are pending. The zone is currently open in all directions, with more drilling planned in this area in 2021.
M ZONE DRILL HIGHLIGHTS INCLUDE1,2:
Hole ID (Az, Dip) (degrees) | From (m) | To (m) | Intercept (m) | Au (g/t) | Au Cut-Off | Hole Length (m) | Target |

KEY POINTS:
SOUTHWEST EXTENSION
The Southwest Extension lies to the southwest of the historic CD Pit and I Pit complex, in an area with a large gold-in-soil anomaly with no previous drill testing. Nine holes tested the soil anomaly. Shallow intervals of oxide gold were encountered in each hole, with the most substantial interval over a 15.2 m interval from surface in LBP200. Gold mineralization appears to be related in part to a northeast-southwest striking fault that separates the CD and I pits. Additional follow-up drill testing will be conducted in 2021.

Hole ID (Az, Dip) (degrees) | From (m) | To (m) | Intercept (m) | Au (g/t) | Au Cut-Off | Hole Length (m) | Target |

KEY POINTS
2020 RC drilling at Black Pine concluded on December 17, with assays pending from 38 holes. The core drilling program, focused primarily on obtaining large-diameter core for metallurgical testing, was completed on November 7, 2020, with assays pending from 10 holes. Liberty Gold drilled a total of 46,227 m in 170 holes in 2020, including 43,875 m of RC and 2,342 m of core drilling.
In addition to RC drilling, Liberty Gold is expanding the drill permit area to access an additional 4.6 km2 of the Black Pine gold system.
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.
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.
