Blackrock Silver's Partner Tearlach Announces Three Additional Core Drillhole Results with Significant Lithium Intercepts at Tonopah North

02.05.2023 | 12:30 Uhr | Newsfile

Vancouver, May 2, 2023 - Blackrock Silver Corp. (TSXV: BRC) (the "Company" or "Blackrock") is pleased to announce that Tearlach Resources Ltd. ("Tearlach") has reported lithium results for three additional core holes from its Phase-1 core drilling program at the Company's Tonopah North Lithium project ("Gabriel"). Tearlach continues to intersect significant grade and thickness in their Phase-1 core program. Assays for these three core drillholes show higher than expected lithium values as compared to the original discovery drilling and have established an expanded mineralized blanket covering an area 2.0 by 2.75 kilometres (km).

Tearlach has now reported eight of its eleven core holes from its Phase-1 core drilling program, with lithium assays pending for the remaining three drill holes. All reported drillholes from the phase-1 core program have intersected thick zones of significant lithium mineralization above 400 parts per million (ppm) Lithium (Li) cut-off, each with higher grade intervals above 1,000 ppm Li.

Tearlach's drilling continues to confirm Blackrock's original Gabriel lithium discovery, albeit grades from its phase-1 core program are 40-85% higher than the corresponding original Blackrock reverse circulation intercepts. Tearlach's assay results have increased the average lithium grade of the drill intercepts and show significant expansion potential of the lithium-bearing horizon(s), with the system remaining open to the south and west, and additional assays are pending from the northern and southeastern extents of the property. The Gabriel project is situated in West Central Nevada along the emerging Tonopah lithium belt, adjoining American Lithium Corp's TLC deposit.

According to the May 1, 2023, news release issued by Tearlach (the "Tearlach Release"), the following highlights were reported for the Gabriel project:


  • all three (3) newly reported drillholes had lithium assays greater than 1,000 ppm Li, with the highest value being 1,410 ppm Li over 1.8 feet (0.55 metres).;
  • GAB-005 returned the longest interval of 94.2 feet (28.7 metres) grading 541 ppm Li including 17.6 feet (5.36 metres) grading 860 ppm Li;
  • GAB-004 cut the thickest lithium intercept with a grade of 703 ppm Li over 27.1 feet (8.26 metres);
  • thick zones of lithium mineralization above a 400 ppm cut-off grade have been intersected in all of the reported drillholes from the Phase-1 program. Three core holes have assays pending;
  • to date, drillholes show excellent geological continuity of claystone stratigraphy in all core holes suggesting an area covering 2.0 km by 2.75 km in size; and
  • bordering American Lithium's TLC deposit (maiden PEA outlined a positive investment base case after-tax NPV(8%) US$3.26 Billion & After-tax IRR of 27.5%)1, Gabriel shows similar lithium-bearing lithologic horizons and similar potential to host a significant lithium deposit immediately adjacent to a major highway, US95, and just outside of the town of Tonopah. There is no assurance that mineralization comparable in size or scale to that on adjacent properties will be discovered on Gabriel.

Andrew Pollard, President and Chief Executive Officer of Blackrock, commented: "We are highly encouraged by Tearlach's latest drilling results, which suggest that the lithium-bearing system at the Gabriel project continues to be more extensive and high-grade than initially thought. The three additional core holes reported today have expanded the footprint of mineralization, establishing continuity across an area of 2.0 km by 2.75 km while skewing the average grades at the project higher. Drilling indicates that the system remains open to the south and west, with the potential for even further expansion pending assays for the remaining three drillholes from this program. With a maiden resource estimate planned by the end of the year, we see potential for significant value to be unlocked for our shareholders as this discovery is advanced."

Blackrock and Tearlach are parties to an option agreement dated January 10, 2023 (the "Option Agreement") wherein, among other things, Blackrock has granted Tearlach an option to acquire, in two stages, up to a 70% interest in the lithium minerals in certain unpatented mining claims forming a portion of Gabriel. Upon incurring exploration expenditures of US$5,000,000 within three years, Tearlach will have earned a 51% interest in Gabriel, and upon incurring cumulative exploration expenditures of US$15,000,000 and completion of a Feasibility study within 5 years, Tearlach will have earned a 70% interest. Pursuant to the Option Agreement, Tearlach has the exploration rights from surface to 650 feet (200 metres) below the topographic surface to explore for lithium. Blackrock retains the rights to all other minerals including gold and silver at Gabriel.
