TN22 Re-Assay Highlights:
- A lithium intercept (minimum 15 feet (4.6m) interval at a 400 ppm cutoff grade) has been intersected in five (5) of the six (6) TN22 holes reported here.
- Longest intercept of lithium mineralization for the six (6) holes is 130 feet (39.6m): Hole TN22-011.
- Highest primary intercept grade is 836 ppm Li over 70 feet (21.3m): Hole – TN22-012.
- Highest grade for an “Included intercept” is 984 ppm Li over 40 feet (12.2m), including 1,660 ppm: Hole TN22-012.
- Highest value for the reported six (6) holes is 1,600 ppm lithium: TN-012.
- Re-assay primary intercept values are 14 – 33% higher than the corresponding intercept values for the original TN22 assays.
- Expands Tearlach defined mineralization to the southwest.
“The TN22 re-assay program contributes valuable data to the Gabriel Phase 1 drill database, confirming consistently higher assay grades compared to the original drilling. These re-assays significantly enhance data density in specific areas of the Gabriel property and expand the zone of defined mineralization to the southwest,” explained
Technical Information:
The table below reports the summary TN22 pulp re-assay results for holes TN-010 through -015. BRS also conducted a limited pulp re-assay program (49 samples) in
- BRS drilled TN22-010 at a location that is southwest of the Gabriel drill pattern. The hole was drilled on a westerly azimuth at an inclination of -75 degrees to a depth of 2,500 feet (762m - see collar file below). The re-assay data indicates a modest thickness and grade of lithium mineralization.
- TN22-011 & TN22-012 were drilled from the same drill site as GAB-006 (a vertical hole). Hole 011 was drilled in a northerly direction at an inclination of -50 degrees to a depth of 505 feet (154m). The re-assay data indicates that the hole intersected two (2) zones of lithium, with the deeper intercept being of greater length and grade. Hole 012 was drilled southward at an inclination of -50 degrees. The re-assay data indicates that this hole also intersected two intervals of lithium mineralization, with the deeper intercept being of greater length and grade. The results from these two holes compare well to GAB-006: primary intercept of 77.9 feet (23.7m) at 707 ppm Li.
- TN22-013 was drilled from the same drill site as GAB-004 (a vertical hole). The hole was drilled northerly at an inclination of -50 degrees. The re-assay data indicates that the hole intersected 55 feet of lithium mineralization, grading 559 ppm (highest individual value at 1,100 ppm). The TN22-013 results compare reasonably well to the GAB-004 results: primary intercept of 27.1 feet (8.3m) at 703 ppm Li.
- TN22-014 was drilled from the same drill site as GAB-005. The hole was drilled northerly at an inclination of -50 degrees. The re-assay data indicates that the hole intersected two (2) narrow zones of lithium mineralization.
- BRS drilled TN22-015 (southern portion of the property) between TN22-010 and -013. The hole was drilled northerly at an inclination of -50 degrees. The re-assay data indicates that the hole did not intersect a minimum 15 feet interval of lithium mineralization at a cut-off grade of 400 ppm.
Assays are pending for an additional six (6) holes and include TN22-002, which is just south of the Gabriel property boundary on lands that remain under the control of BRS. Although not drilled on the Gabriel property, this re-assay data will be used to calculate block grades in the Gabriel model in an area where there is no GAB drilling.
