Liberty Gold Expands Near-Surface Mineralization in M Zone and Completes 2021 Resource Upgrade and Step-Out Drilling at Discovery Zone, Black Pine

 

 

 

 

M Zone: LBP564: 2.51 g/t Au over 15.2 m; LBP542: 0.56 g/t Au over 53.3 m

 

Discovery Zone: LBP407: 0.49 g/t Au over 48.8 m, including 0.61 g/t Au over 35 m

 

 

Liberty Gold Corp. (TSX: LGD) (OTCQX: LGDTF) is pleased to announce results from the 2022 winter reverse circulation drill program at the M Zone, and final results from the 2021 resource upgrade and step-out drilling program at the Discovery Zone at the Black Pine oxide gold deposit in southern Idaho.

 

The M Zone, located east of Discovery Zone, is a focus of our 2022 drill program given the near-surface mineralization and proximity to lower elevation areas to the east that might be suitable for heap leach infrastructure. Results from the 2022 winter drill program delivered relatively high-grade oxide gold mineralization at shallow depths (~30 to 80 meters below surface). The current resource contains two pits in the M Zone and today’s results targeted the 250 m gap between these two pits, with the primary objective to link mineralization into a single larger deposit over a 750 m length.

 

Drilling is currently underway to the southwest of the M Zone, testing a 650 m gap in bedrock drilling overlain by a historic waste dump that potentially contains mineralization between the historic Tallman and CD pits, with the goal of linking mineralization within this entire corridor from M Zone to CD Zone, a distance of over 2 kilometres.

 

At the Discovery Zone, infill drill results continue to confirm and increase confidence in the broad continuity of oxide gold mineralization across the Discovery Zone, which hosts 74% of the current Black Pine resource ounces. Step-out drilling in areas surrounding the Discovery Zone, suggests that several of these zones can potentially be merged into a single, contiguous resource area ultimately linking to the main Discovery Zone pit.

 

Liberty Gold continues to advance its 87,000 m drill program in 2022 and has delivered strong early returns at both Rangefront and now at the M Zone. This illustrates the success this year’s program has had so far in discovering, linking up and expanding mineralized areas across the entire deposit and will continue to be a key focus of our exploration program this year.

 

Cal Everett, President and CEO of Liberty Gold stated, “The 2021 drill campaign continued to deliver strong results further demonstrating Black Pine as a large-scale gold deposit in the Great Basin. The notable 2021 success was the Rangefront discovery, but step-out and in-fill results within the Discovery Zone and surrounding areas also continue to add value to the deposit. By the end of 2022 Liberty Gold will have completed approximately 150,000 additional metres of drilling subsequent to our first resource estimate at Black Pine.”

M ZONE HIGHLIGHTS:

  • The M Zone is located to the east of the Discovery Zone and consists of relatively high-grade mineralization at shallow depths in two small resource pits, separated by a previously undrilled, 250 m gap.
  • Drilling in this area in early 2022 yielded shallow, relatively high-grade oxide gold intercepts in the gap between the two resource pits, raising the possibility that the two pits might join into a larger pit over a 750 m length.
  • The M Zone is a focus of our 2022 drill program given the near-surface mineralization and proximity to lower elevation areas to the east that might be suitable for heap leach infrastructure.

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 thicknesses are reported herein; true width varies depending on drill hole dip, but generally ranges from 60% to 80% of true thickness. Gold grades are reported uncapped Some deep intervals in this area report reduced cyanide solubility resulting from the presence of organic carbon. For a full table of results for this release, please see the link above.

 

DISCOVERY ZONE RESOURCE UPDGRADE HIGHLIGHTS:

  • In 2021, Liberty Gold drilled a total of approximately 14,500 m in 72 holes in the Discovery Zone, with the goal upgrade the 18% of the resource classified as inferred to indicated.
  • A secondary purpose of the 2021 drilling was to gain a better understanding of the grade distribution in the 0.1 grams per tonne gold (“g/t Au”) to 0.2 g/t Au range to choose a suitable cut-off grade for future engineering studies.
  • Infill drill results continue to confirm and increase confidence in the broad continuity of oxide gold mineralization across the Discovery Zone.
  • Results include near-surface drilling in shorter holes that was critical to fill-in previous gaps within the resource model

DISCOVERY ZONE STEP-OUT HIGHLIGHTS

  • Step-out holes were drilled between the E Zone and Discovery Zone; to the southwest of the Discovery Zone in the F Zone; and in the southern extension of the Discovery Zone into the historic Tallman Pit area. The purpose of these holes was to expand known mineralized centres and ascertain if they will all coalesce in the future into a single, continuous mineralized zone.
  • Shallow gold mineralization was encountered in the area between the Discovery Zone and E Pit, a distance of over 300 m, potentially linking these areas into a larger pit.
  • The F Zone is defined by shallow gold oxide intercepts in widely spaced drilling, resulting in several small resource pits. The current drilling reinforces the likely continuity of this zone, with more drilling planned in the near future.
  • Further drilling in the vicinity of the historic Tallman Pit continues to add to the gold endowment in that area.
  • Step-out drilling around the Discovery Zone in three directions will be ongoing in 2022 and shows encouraging indications that several smaller resource pits (E Zone, F Zone, etc.) may eventually merge with the Discovery Zone to form a single, larger pit inclusive of more gold mineralization

2022 WORK PROGRAM

 

The 2022 exploration program at Black Pine commenced in January, with three RC and one core rig active. Drilling through to the end of February focused on the lower-elevation RFA and M Zone with the goal to continue resource expansion and confirmation, with the core drill focused on metallurgical testing. On March 1, two drills were moved to Goldstrike to commence engineering, resource upgrade and metallurgical drilling, while two drills remain at Black Pine to focus on step-out drilling and new target testing.

 

Liberty Gold plans to aggressively advance Black Pine in 2022 with drilling, initial engineering and permitting programs and further de-risking activities, with the goal to provide an updated resource estimate and Preliminary Economic Assessment in the second half of 2022, subject to exploration success.

 

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, 2021, 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 cut-offs of 0.15 g/t Au, 0.20 g/t Au, 1.0 g/t Au and 5.0 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.
