Liberty Gold Announces Maiden Resource Estimate for Goldstrike Deposit, Utah

VANCOUVER, British Columbia, Feb. 08, 2018 (GLOBE NEWSWIRE) -- Liberty Gold Corp. (TSX:LGD) ("Liberty Gold" or the "Company") is pleased to announce a maiden independent resource estimate at its Goldstrike Oxide Gold project in southwestern Utah. This resource estimate crystallizes 3 years of data compilation and drilling, and is a strong foundation on which to layer engineering, metallurgical studies, as well as ongoing expansion drilling. It is a key asset in Liberty Gold’s portfolio of advanced-staged, Carlin-style gold projects in the Great Basin of the USA.

The Classified Mineral Resource estimate is quoted at a cut-off grade of 0.25 grams per tonne gold (g/t Au) and consists of:

• An indicated resource of 865,000 ounces of gold at an average grade of 0.54 g/t Au (49,553,000 tonnes); and
• An inferred resource of 274,000 ounces of gold at an average grade of 0.52 g/t Au (16,443,000 tonnes).

Commenting on these results, Cal Everett, President and CEO of Liberty Gold stated, “We are thrilled to release the first resource estimate for our flagship Goldstrike Property, the result of three years of hard work by our brilliant geological team. We have exceeded our initial resource target expectation and will continue to drill and expand the Goldstrike Deposit as well as the new discoveries that surround it. This is an important first step in turning a 24 year-old, past-producing mine into a modern, multi-million ounce mining project.”

KEY POINTS

• The resource captures drilling in the Historic Mine Trend, comprising the Main - Dip Slope, Peg Leg and Western zones, as well as the Mineral Mountain area.
  
  
• At higher cut-off grades, much of the resource is retained, potentially providing optionality in mine planning scenarios.
  
  
• A combination of historic and Liberty Gold drilling in 1,730 tightly-spaced drill holes, representing 153,000 metres of drilling, allows for the resource estimate to have a high degree of confidence, as illustrated by over 75% of the resource in the Indicated category.
  
  
• Most of the property remains unexplored or incompletely tested, including large areas extending from the Dip Slope zone that remain open in several directions for resource expansion.
  
  
• Metallurgical results indicate rapid gold recoveries, relatively insensitive to crush size, which support a simple, low cost, run-of-mine heap leach process. Metallurgical test work by Liberty Gold shows that greater than 80% of the gold is recovered within the first 10 days of column leaching.

Drilling will recommence on approximately March 1, 2018. Drilling will focus on expanding the resource, as well as testing of new targets property-wide.

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 and an average recovery of approximately 75%.

ESTIMATION METHODS

The resource estimate was completed by James N. Gray, P.Geo. of Advantage Geoservices Ltd., an Independent Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. Mr. Gray is the Qualified Person for this news release. Estimation methods are summarized below. Further details of the estimation methods and procedures will be available in a NI 43-101 technical report, to be co-authored and released by SRK Consulting (Canada) Inc. (“SRK”), which will be filed on SEDAR (www.sedar.com), within 45 days from the date of this release.

Geologic controls for resource estimation are based on the geologic interpretation provided by Liberty Gold. Gold mineralization is primarily associated with a series of steeply dipping normal-oblique fault zones as well as with a low-angle unconformity surface (“Control Surfaces”). Gold grades have been estimated by inverse distance squared (ID²) interpolation into 10 m³ blocks. Sample selection during estimation is based on distance to the Control Surfaces and, in this way, reproduces the concentric or banded nature of fault zones and stratigraphic trends. Density has been applied at an average value of 2.52 t/m³ based on 159 measurements carried out by Liberty on drill core.

The Mineral Resource estimate is supported by 1,730 holes, totaling 153.0 km, that fall inside the limits of the block models. Samples were composited to the average sample length of 1.524 m (5 feet) prior to use in grade estimation; 102,264 composites are contained inside the modelled volume. Statistical evaluation of composite data by fault and stratigraphic zones led to the establishment of high-grade capping limits by control surface. In total, 349 composites were capped for use in resource estimation.

The Mineral Resource has been classified based on available drill data as well as by proximity to the interpreted geologic controls. Inferred Mineral Resource blocks are within 50 m of a sample or must be estimated by at least two holes. Indicated Mineral Resource blocks must lie within 40 m of sample data and must be estimated by at least three holes if within 40 m of a Control Surface or by at least two holes if within 30 m of a Control Surface.

Reasonable prospects of eventual economic extraction were established through the generation of Whittle optimized pit shells; all reported resource is contained within those shells. Optimization parameters were (in U.S. Dollars): $2.25/tonne (t) mining cost; $4.30/t processing and G&A cost (assuming Run of Mine Heap Leach operation); 50 degree pit slopes; and $1500/oz gold less $2.20 selling cost. An economic internal cut-off grade was estimated at 0.13 g/t Au. Based on on-going metallurgical studies, recovery was variable depending on head grade: Au ≥ 0.4 g/t - rec% = 0.8133*Au^0.0677; Au < 0.4 g/t - rec% = 0.8491*Au^0.1301.The Whittle pit model was produced by Grant Carlson, P. Eng. of SRK, an Independent Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects.

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 AAS. Metallic screen techniques may be employed where the presence of coarse free gold is suspected. Approximately 1000 grams of coarse reject material are pulverized and screened. Two splits of the fine fraction are assayed, as well as all material that does not pass through the screen (the coarse fraction). The final gold assay reported is a weighted average of the coarse and fine fractions. 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.

The mineral resource estimates referenced in this press release use the terms "Indicated Mineral Resources" and "Inferred Mineral Resources."

"Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves" as in-place tonnage and grade without reference to unit measures. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. Liberty Gold is not an SEC registered company.
