Liberty Gold Announces Results of Infill and Step Out RC Drilling along the Northern Edge of the Main Goldstrike Deposit, Great Basin, USA






Liberty Gold Corp. (LGD-TSX) is pleased to announce results from its 2018 Reverse Circulation drilling program at the Goldstrike Project, the flagship of its three principal gold projects located in the prolific Great Basin of the United States. Located in southwestern Utah, Goldstrike is a past-producing oxide – heap leach gold mine that contains a large, shallow, district-scale, Carlin-style gold system.


The northern portion of the Main Goldstrike Deposit was tested with RC holes pursuant to infilling gaps in the existing resource model.  Mineralization in this area, known as the Dip Slope zone, is relatively shallow and drilling in 2018 was restricted to widely spaced, pre-determined roads and pads.  With the receipt of an amendment to the Plan of Operations that permits placement of roads and pads in optimal locations (see press release dated November 29, 2018), additional drilling is planned in 2019 that will fully address the infill drilling program.  The new Plan of Operations opens up over 2 square kilometres of new ground on the northern boundary to the Goldstrike Deposit for resource expansion.


Drill Highlights include:




  • 2.09 grams per tonne gold (g/t Au) over 16.8 metres (m) including 3.94 g/t Au over 7.6 m; and 0.90 g/t Au over 12.2 m in PGS615
  • 1.08 g/t Au over 12.2 m in PGS493
  • 0.39 g/t Au over 3.0 m and 0.48 g/t over 1.5 m and 0.69 g/t Au over 1.5 m and 0.49 g/t Au over 18.3 m and 2.42 g/t Au over 3.0 m in PGS674
  • 0.28 g/t Au over 3.0 m and 0.36 g/t Au over 4.6 m and 0.72 g/t Au over 12.2 m in PGS675




  • Drilling in the northern Main Goldstrike Deposit (Dip Slope Zone) area continues to expand mineralization along the shallowly north-dipping Claron Formation unconformity, with higher-grade intervals located along west-northwest-striking faults.
  • Mineralization in this area is shallow, and, with infill drilling in 2018 restricted to previously-defined, widely-spaced drill sites, additional drilling will be necessary in 2019 in order to reduce the drill intercept spacing in this area with a goal to expand the current resource.
  • 2019 drilling will be greatly aided by the receipt of an amendment to the Plan of Operations that will allow for drill sites to be placed where needed.
  • 2018 Results will be incorporated into an updated resource estimate in Q1 – Q2, 2019.




Results have also been received for drill holes testing back-filled areas of two nearby historic pits in the Main Goldstrike Deposit. 


Drill Highlights Include:


  • 0.37 g/t Au over 22.9 m in PGS640 in the Hamburg Pit backfill area
  • 1.58 g/t Au over 4.6 m in PGS610 in the Hassayampa pit backfill area




  • Testing of backfilled areas of the historic pits continues to identify areas of above cut-off backfill material.
  • These areas are currently classified as waste in the resource model and will be further tested and included in subsequent resource estimates.

Liberty Gold drilled a total of 24,716 m in 200 RC and 15 diamond core holes in 2018.  The objective of the drilling reported below was to continue to push the pit-constrained resource outward and downward, to grow the resource and convert Inferred resources to Indicated resources.


Liberty Gold continues to meet its project enhancement goals in 2018, commencing with a maiden resource estimate released in February1. A subsequent Preliminary Economic Assessment (“PEA”)2 is based on this resource, which includes drill results through the end of 2017.  The 2018 reverse circulation program was completed on November 1. The program focused on 1) infill and expansion of the resource; 2) testing of the historic heap-leach, stockpile and waste dump areas that are largely situated within the PEA pit and counted as waste in the model (see press release dated August 16, 2018); and 3) 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%.


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 AAS.  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.



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.
