ASSAY RESULTS CONFIRM BE AND NB-TA OXIDE-BEARING PEGMATITES ON TEARLACH'S GEORGINA PROPERTIES

Tearlach Resources Ltd. has received assays confirming the presence of key lithium (Li) indicator minerals (Li-rich muscovite, beryl and niobium-tantalum-oxide minerals) at Parks Lake on the Georgina properties, Jellicoe, Northern Ontario. The project is located nine kilometres east of Rock Tech Lithium's Georgia Lake property and is being explored for lithium mineralization hosted in spodumene pegmatites.

Assay highlights:

  • 0.62 per cent Li2O (lithium oxide), 5,030 parts per million (ppm) Rb (rubidium), 1,880 ppm Cs (cesium) and 122 ppm Ta (tantalum) in green muscovite pod sample 889653, Oxide Island;
  • 10.43 per cent BeO (beryllium oxide), 904 ppm Cs and 0.22 per cent Li2O in pure pale green beryl sample 889539, Beryl Island;
  • 3.31 per cent Ta, 12.50 per cent Nb (niobium) in pure black Nb-Ta-oxide mineral sample 889654, Oxide Island. These are up to five centimetres (cm) in diameter and are among the largest Nb-Ta-oxide mineral crystals in Ontario.

The presence of Li-rich muscovite, beryl and Nb-Ta-oxide minerals in rare-element pegmatites indicates that there is a strong potential for the pegmatites to contain spodumene. The 2.6-kilometre strike length of rare-element mineralization is the focus of Tearlach's continuing field exploration program.

Tearlach has identified a rare-element pegmatite zone. This zone is where all of the rare-element minerals and elements are concentrated on the property, that is, beryl, Nb-Ta-oxides, Li, Rb, Cs, Nb, Ta and Be, which all increase with proximity to the spodumene. Tearlach's next steps to find spodumene are to focus the prospecting on the rare-element pegmatite zone to look for the spodumene. The Georgina properties are 12 km by 26 km in size, and identification of the rare-element pegmatite zone has narrowed down the search considerably.

Dr. Julie Selway, Tearlach's vice-president of exploration, exclaimed: "I am excited about the discovery of beryl and Nb-Ta on the islands on Parks Lake. The anomalous rare elements suggest that lithium mineralization is nearby. I can't wait to see more results from the field crew."

Quality control

Grab samples include representative samples of granite, pegmatite, metasedimentary rocks and diabase on the project area. The grab samples were delivered by Tearlach geologists to Actlabs, Geraldton or Thunder Bay preparation labs. Samples were assayed by Actlabs, Ancaster analytical lab, which is an ISO 17025 accredited laboratory. The samples were digested using lithium metaborate/tetraborate fusion and assayed by inductively coupled plasma optical emission spectroscopy and inductively coupled plasma mass spectrometry for whole rock major oxides and trace elements (that is, 4Litho-Pegmatite Special package). Lithium oxide percentage was digested using sodium peroxide fusion and assayed using ICP-OES. Actlabs inserted standards, blanks, pulp duplicates and prep duplicates into the sample stream.

About Tearlach Resources Ltd.

Tearlach, a member of the TSX Venture 50, is a Canadian exploration company engaged in acquiring, exploring and developing lithium projects. Tearlach is focused on advancing its flagship Gabriel project in Tonopah, Nev., bordering American Lithium's TLC deposit, and has completed 11 drill holes on the Gabriel property. Tearlach has three lithium assets in Ontario: Final Frontier, Georgina Stairs and New Frontier. Final Frontier is located adjacent to and near Frontier Lithium's PAK lithium deposit north of Red Lake. Georgina Stairs is located northeast of Rock Tech Lithium's Georgia Lake deposit near Beardmore. Tearlach has two lithium assets in Quebec: the Rose-Fliszar-Muscovite project in the James Bay area and the Shelby project adjacent to and near Patriot Battery Metals' Corvette lithium project and Winsome Resources' Cancet and Adina lithium projects. Tearlach also has the Savant property, an exploration-stage gold-silver-copper property, in Northwestern Ontario. Tearlach's primary objective is to position itself as North America's leading lithium exploration and development company.
