VANCOUVER, British Columbia, July 20, 2023 (GLOBE NEWSWIRE) -- Tearlach Resources Limited (TSXV: TEA) (OTC: TELHF) (FRANKFURT: V44) ("Tearlach" or the "Company") is pleased to provide an update on progress with its summer exploration program on the Georgina Properties, Jellicoe, northwestern Ontario. The Properties, consisting of the Georgina Stairs, Georgina East and newly staked claims, cover approximately 239 square kilometres (Figure 1) and are being explored for pegmatite-hosted lithium mineralization similar to that hosted on Rock Tech's Georgia Lake Property to the west. Fieldwork consisting of geological mapping and outcrop sampling commenced in mid-May, and to date, approximately 20% of the Properties have been covered.

Highlights:

A key milestone is the discovery of eleven pegmatite outcrops, including both sodium and potassium-rich varieties. These are the first documented pegmatites on the property, and the presence of both sodic and potassic types indicates that fractionation of the pegmatite melt has occurred, which could generate lithium-rich end member components. Tearlach's ongoing geochemical sampling program will focus on establishing geochemical and mineralogical vectors towards possible lithium-enriched areas of the system.

Based on the pegmatite discoveries, in June, Tearlach staked an additional 46 claims contiguous with the southern part of Georgina East Property on open ground (Figure 1). The Georgina Properties now consist of 1131 cell claims and is 26 km by 12 km in size.

Exploration Targets:

The spodumene-bearing pegmatites elsewhere in the region are sodic-rich, with aplite in the outermost zones and green muscovite in the innermost zones associated with spodumene. The identification of both aplite and green muscovite during the recent work on the Properties indicates that it has the potential to host spodumene pegmatites. Tearlach's exploration team will be focusing on these areas in the upcoming month.

Dr. Selway stated that, "I am happy with the progress that Tearlach's mapping team has made at the Georgina Properties. We have progressed from an unexplored property to discovering granites to discovering pegmatites within 2 months. Tearlach's Georgina Properties has the potential to host lithium mineralization like Rock Tech Lithium's Georgia Lake Property 9 km to the west."
