Tearlach Commences Mapping at Georgina Stairs, Jellicoe, Ontario

VANCOUVER, British Columbia, June 27, 2023 (GLOBE NEWSWIRE) -- Tearlach Resources Limited (TSXV: TEA) (OTC: TELHF) (FRANKFURT: V44) (“Tearlach” or the “Company”) is pleased to announce that it has started mapping and sampling on our Georgina Stairs Lithium Project in the Georgia Lake pegmatite field, Jellicoe, Ontario. Mapping targets are being generated daily and followed up by Tearlach’s geology team. The Project is located 9 km east of Rock Tech Lithium’s Georgia Lake Project and is being explored for lithium mineralization hosted in spodumene pegmatites.

Highlights:

• Data compilation on the Project area, including topography, geology and geophysics data, was completed in the spring of 2023 and used to identify specific exploration targets in the Project area.
• Satellite images were used to identify outcrops, access roads and logged areas.
• 172 sample locations were described in the month of May.
• 76 samples have been submitted to the lab for assays.
• 20 granite outcrops were discovered and sampled.
• Tearlach signed an MOU with four local First Nation communities.

Tearlach’s geology team has discovered 20 granite outcrops hosted by biotite metasedimentary rocks on the Georgina Stairs claim block, whereas previously Ontario Regional Geology Map (MRD126) indicated that there was no granite on the claim block (Figure 1). The medium- to coarse-grained biotite granite outcrops occur in the southern part of the claim block. The mapping results have been interpreted and indicate three (3) exploration target areas for additional mapping. The discovery of granite is important because pegmatite dykes are derived from granite. For example, Rock Tech’s spodumene pegmatites are hosted by metasedimentary rocks in close proximity to granites.

A total of 172 sample locations were described in the month of May, of which 76 samples were submitted to Actlabs, Geraldton location for assay. Results are pending. The samples include granite to examine their rare-element content and metasediments to examine rare-element metasomatism as an indicator of blind pegmatites. Diabase was also sampled to distinguish between different generations of sills and dykes to see if one generation is associated with pegmatites. The Li, Rb, Cs, Nb, Ta and Be content of the granite will be plotted on a map to determine in which direction these rare-elements are increasing. This will be the direction to look for the possible presence of pegmatites.
