Tearlach Resources Channel Samples up to 4.04 % Li2O over 0.70 m on Georgina Properties

VANCOUVER, BC / ACCESSWIRE / November 28, 2023 / Tearlach Resources Limited (TSXV:TEA)(OTCQB:TELHF)(FRANKFURT:V44) ("Tearlach" or the "Company") is pleased to announce that we have received the assay results from the channel samples cut on Riches Spodumene Pegmatite, Parks Lake, Georgina Properties, Northwestern Ontario. Fifteen channel samples were cut over 3 channels on the pegmatite as a follow-up on our spodumene discovery (Tearlach press release dated Oct. 18, 2023). The assays confirm the high-grade lithium mineralization on the spodumene pegmatite and justify the upcoming drill program.

Riches Pegmatite assay highlights (Table 1):

• 4.04 % Li₂O over 0.70 m, sample 889594, channel GS-CH-23-03, inner core zone (Figure 1).

• 3.53 % Li₂O and 595 ppm Ta over 1.00 m, sample 889591, channel GS-CH-23-03, blue spodumene zone (Figure 2).

• 2.45 % Li₂O over 4.70 m, channel GS-CH-23-03, blue spodumene zone and inner core zone

• 2.53 % Li₂O over 1.31 m, channel GS-CH-23-02, green spodumene zone

Riches Pegmatite is open along strike of the peninsula and down dip. The north end of channel GS-CH-23-03 is coarse-grained spodumene covered by overburden and tree roots. A test pit dug by hand 7 m northeast of channel GS-CH-23-03 discovered more coarse-grained green spodumene beneath overburden. Mechanical stripping is required to fully expose the spodumene mineralization on Riches Pegmatite. Rare-element mineralization in the Parks Lake area extends along a 2.6 km strike length (Figure 4). This 2.6 km rare-element pegmatite zone has seven pegmatite dykes with beryl, Nb-Ta-oxides and muscovite books indicators suggesting that more spodumene pegmatites will be found.

Riches Pegmatite on Georgina Properties has excellent infrastructure as it is:

• Located 23 km from the Trans Canada Highway #11 and a power line,

• Located 930 m from Camp 51 Roads and is accessible by road and boat.

• 250 km from year-round port on the Great Lakes and transportation hub in Thunder Bay.

Tearlach Resources has submitted a drill permit application to the Ontario Ministry of Mines and expects approval in Q1 2024.

Dr. Julie Selway, VP of Exploration, exclaimed "I am impressed with the Lithium assays on the channel samples which confirms the high-grade spodumene mineralization seen in outcrop. I am looking forward to a maiden drill program on the Georgina Properties in Q1 2024."

Riches spodumene pegmatite has an exposed width of 12 m and length of 9 m with crystals up to 70 cm long (Figure 3). The spodumene pegmatite is hosted by coarse-grained biotite-muscovite granite. The pegmatite has 3 spodumene-rich zones: green spodumene zone, blue spodumene zone and inner core zone with abundant very coarse-grained green spodumene crystals. Channel sample collar locations are given in Table 2.

Quality Control:

Tearlach submitted to Actlabs a total of 452 samples of which 437 were grab samples and 15 were channel samples. 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 ICP-OES and ICP-MS for whole rock major oxides and trace elements (i.e., 4Litho-Pegmatite Special package). Li₂O % was digested using sodium peroxide fusion and assayed using ICP-OES. Actlabs inserted standards, blanks, pulp duplicates and prep duplicates into the sample stream. Tearlach inserted one lithium external standard and one blank into the sample stream for every 20 samples. The external standards are OREAS 147 and OREAS 148, and the external blank is quartz chips. All standards and blanks passed a Quality Control review.
