Liberty Gold Announces D-4 Discovery at Rangefront, Black Pine Oxide Gold Deposit, Idaho

 

 

 

 

 

LBP356: 0.91 g/t Au over 86.9 m and 2.03 g/t over 21.3 m
LBP358: 1.23 g/t Au over 24.4 m and 1.37 g/t Au over 50.3 m

 

Liberty Gold Corp. (TSX: LGD) (OTCQX: LGDTF) is pleased to announce the new D-4 gold discovery at the Rangefront target on its Black Pine Oxide Gold deposit in southeastern Idaho, confirmed with the release of the first tranche of 2021 Reverse Circulation drill results.

 

D-4 discovery drill holes LBP356 and LBP358 were drilled from the first site established in the new permit area targeting a 1,250 metre gap in drilling along the four kilometre long dominant mineralization trend at Black Pine. This large gap between two mineralized areas had seen no previous drilling due to the presence of shallow sandstone cover rocks that overlie the gold-host carbonate rocks. The two +100 gram-metre oxide gold intercepts are spaced approximately 100 m apart and are characteristic of other high grade oxide gold zones across the property.

 

Cal Everett, President and CEO of Liberty Gold stated, “D-4 at Rangefront represents another game-changing discovery for Black Pine in a completely untested area of the property. With mineralization in the Discovery Zone trending southeast under sandstone cover, we believed the Rangefront area had potential to host the faulted-off, southern extension of the Black Pine gold system. While it is still early days, with the high-grade intervals in LBP356 and LBP358 and mineralization over a 400 m down-hole interval in LBP349, we have proof of concept that significant gold mineralization exists in the D-4 area. We are now aggressively drilling at D-4 and expect to continue through the remainder of the 2021 drill season. The D-4 discovery, along with new frontier discoveries at Rangefront Southwest and Upper F Zone also released today, continues to demonstrate the large-scale and robust nature of the oxide gold system at Black Pine, which remains relatively untested after only two years of concentrated drilling in the Discovery Zone.”

D-4 DISCOVERY HIGHLIGHTS

 

  • Results from the five holes, drilled 350 m west of the Rangefront resource pits encountered thick zones of gold mineralization, including:
    • LBP356: 0.91 grams per tonne gold (“g/t Au”) over 86.9 m and 2.03 g/t Au over 21.3 m
    • LBP358: a 100 m step-out from LBP356 intersected 1.23 g/t Au over 24.4 m, and     1.37 g/t Au over 50.3 m, including 2.37 g/t Au over 22.9 m
    • LBP349 another 100 m step-out south-east from LBP358 returned numerous intervals of above cut-off grade mineralization from 56.4 m to 455.7 m down-hole, a length of approximately 400 m
  • LBP277 located 700 m west of Rangefront yielded an interval grading 6.17 g/t Au over 3.0  m
  • Between LBP277 and the Rangefront resource pits, gold mineralization has been encountered in three locations over a distance of 1.2 km from east to west with mineralized intervals at approximately the same vertical elevation
  • The Rangefront D-4 discovery drill site is located 1,250 m southeast of the southernmost Discovery Zone resource pit, 350 m west of the two Rangefront resource pits, 600 m south of the Rangefront North target (Leach Pad resource pit), and approximately 1 km east of the historic C-D Pit
  • Rangefront is open in all directions, and is undrilled for 600 m to the north and is unconstrained to the south
  • Given the scale of the D-4 target area, two drills have been mobilized from outlying regional targets to Rangefront to expand the discovery

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 cut-off. Downhole thickness is reported herein; true width varies depending on drill hole dip, but generally range from 60 to 80% of true thickness. Gold grades are reported uncapped.

 

RANGEFRONT SOUTHWEST AND UPPER F ZONE HIGHLIGHTS

 

  • The Rangefront Southwest and Upper F Zone targets represent two new oxide gold discoveries in frontier areas that have not been subject to any previous drilling; results include:
  • Rangefront Southwest:
    • LBP290 returned 1.15 g/t Au over 21.3 m, located 800 m south of the C-D pit
    • LBP337 returned 2.1 g/t Au over 13.7 m
  • Upper F Zone:
    • The Upper F Zone is located 300 m south-east and 500 m north-west of the historic E pit and C pit, respectively
    • LBP300 and LBP350 both bottomed in gold mineralization and the holes were abandoned due to bad ground conditions and represent a new discovery in this area
    • LBP350 returned 1.40 g/t Au over 12.2 m
  • Follow up drilling at both Rangefront Southwest and Upper F Zone is on-hold pending drill rig allocation to the D-4 discovery

2021 WORK PROGRAM

 

Drilling commenced April 1st and is focused on upgrading inferred portions of the resource to indicated, step-out drilling on defined targets and discovery drilling throughout the 12 km2 permitted drill area. The initial resource pit encompasses the Discovery Focus Area (D-1, D-2 and D-3 high-grade oxide gold zones) as well as smaller pits at the Rangefront, M, C-D Pit, F, J, E Pit and Back Range zones. The updated Black Pine Oxide Mineral Resource estimate released on July 13 (see below) does not include any drilling conducted in 2021. All zones remain open for extension, with the current drill program focussed on:

  • Building on the recent drill results in the Rangefront area
  • Expanding the Discovery Focus Area resource to the southwest, west, southeast, and east
  • Linking the E Pit to the F Zone and CD Pit and assessing whether this portion of the gold system can be extended to the northeast to link with the Discovery Focus Area
  • Converting inferred ounces to indicated
  • Testing the shallow, high-grade Back Range Zone for the first time.
  • Testing other frontier areas where surface geology and geochemistry suggest the presence of shallow zones of oxide gold

 

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.

A 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, with the resource technical report filed on SEDAR and available on the Liberty Gold website on August 19, 2021.

 

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 a cut-off of 0.20 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 0.200 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.
