Liberty Gold Corp. (TSX:LGD) is pleased to provide an update on field activities at its three flagship Carlin-style gold properties in the eastern Great Basin: Black Pine in southern Idaho, Goldstrike in southwestern Utah and Kinsley in eastern Nevada. All properties are past-producing mines that successfully produced gold in simple, run-of-mine oxide heap leach operation in the 1990s.
BLACK PINE DRILLING
Reverse Circulation drilling at Black Pine continues to return thick, high-grade intervals of Carlin-style oxide gold mineralization. New results from the Discovery 2 Zone expand the footprint of mineralization to a width of 175 metres, remaining open for extension in all directions.
DISCOVERY 2 ZONE DRILL HIGHLIGHTS INCLUDE*:
|Hole ID (Az, Dip) (degrees)||From

The Discovery 2 Zone continues to deliver high grades along a north-striking feeder fault corridor, as well as long intervals of gold mineralization in the footwall area to the east. Liberty Gold believes that the area tested to date represents a small portion of the total strike length of the Discovery 2 Zone. The Discovery 1 and Discovery 2 Zones are projected to converge near the northern margin of and below the historic B Pit, approximately 400 m to the south, with an average historical mined grade of 1.38 g/t Au.
With the new drilling in the Discovery 2 Zone, seven of the top 10 unmined intercepts on the Black Pine Property have been drilled by Liberty Gold, including the top five. (There are 1398 historic holes with greater than 1 gram-meter unmined gold intercepts on the property, compared to 61 holes with reportable intercepts drilled to date by Liberty Gold.)

Core drilling at Black Pine commenced on September 24. The large-diameter core program will obtain material to fulfill several goals, including: Phase 1 metallurgical column testing; specific gravity measurements; gold deportment studies; validation of RC data; and collection of structural, stratigraphic and alteration information.

RC Drilling continues with two RC drill rigs in a 1 km2 area between the historic A Pit, B Pit and A Basin target.
Liberty Gold is pleased to announce results from Phase 1 2019 drilling from its Goldstrike Oxide Gold Project in southwestern Utah. The drilling program focused on extensions to gold mineralization in three portions of the resource area, namely the Western Zone, Main Zone and Dip Slope Zone, for the purpose of further resource delineation. Mineral Resources at Goldstrike currently stand at 57.8 million tonnes grading 0.50 g/t Au for 925,000 Indicated ounces and 19.6 million tonnes grading 0.47 g/t Au for 296,000 Inferred ounces1.
A Preliminary Economic Assessment (“PEA”) with a mine scoped as a simple, low cost oxide heap-leach operation using US$1300/ounce gold price will return an after-tax Net Present Value at a 5% discount rate (“NPV5”) of US$129.5 million dollars, and an after-tax Internal Rate of Return (“IRR”) of 29.4%2. At the current gold price of US$1500/ounce, a sensitivity analysis shows an after tax NPV5 of US$210.6 million dollars and an IRR of 41.5%.

A 1600 metre RC drill program will commence at Kinsley on October 20. Drill holes will target the eastward extension of the Western Flank high-grade sulphide resource that includes 284,000 Indicated ounces at an average grade of 6.04 g/t Au2. A new target in the central portion of the Kinsley Gold trend will also be tested.

Goldstrike is located in the eastern Great Basin, immediately adjacent to the Utah/Nevada border, and is a Carlin-style gold system, similar in many ways to the prolific deposits located along Nevada’s Carlin trend. Like Kinsley Mountain and Newmont’s Long Canyon deposit, Goldstrike represents part of 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 Goldstrike Mine operated from 1988 to 1994, with 209,000 ounces of gold produced from 12 shallow pits, at an average grade of 1.2 g/t Au.
A virtual site tour and 3D model of Goldstrike is available on the homepage of the Company’s website: www.libertygold.ca.
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 and average recovery of approximately 66%.
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, www.libertygold.ca.

Moira Smith, Ph.D., P.Geo., Vice-President Exploration and Geoscience, Liberty Gold, is the Company’s designated Qualified Person for this news release within the meaning of National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and has reviewed and validated that the information contained in the release is accurate. Drill composites were calculated using a cut-off of 0.20 g/t. 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 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 Goldstrike, Black Pine and Kinsley Mountain, all of which are past producing open-pit mines, where previous operators only scratched the surface.
