(TheNewswire)
VANCOUVER, BRITISH COLUMBIA – TheNewswire - October 10, 2023, Tearlach ResourcesLimited (TSXV:TEA) (OTC:TELHF) (FRANKFURT:V44) (“Tearlach” or the“Company”) ispleased to announce that it has discovered key lithium mineralizationindicator minerals (i.e., beryl and Nb-Ta-oxide minerals) inpegmatites on the Georgina Properties, Jellicoe, northern Ontario,during the 2023 summer exploration program. The Project is located 9km east of Rock Tech Lithium’s Georgia Lake Project and is beingexplored for lithium mineralization hosted in spodumene pegmatites.This is the first time that beryl and Nb-Ta-oxides have beenidentified on the Project area.
Highlights:
-
Sampling on newly staked claims on Parks Lake hasidentified rare-element pegmatites with beryl, Nb-Ta-oxides andgarnet.
-
Discovered up 5 cm beryl on Parks Lake, sample 889509( Figure1
-
Discovered Nb-Ta-oxide minerals 5 cm in diameter onParks Lake, sample 889654 ( Figure 2
-
Assays indicate anomalous Be, Rb, Cs, Nb, Ta and Sncontents in pegmatites on the Property.
-
Tearlach’s geology team will target areas alongstrike of the rare-element pegmatite outcrops as the presence of beryland Nb-Ta-oxides are typically associated with lithium mineralization.
Georgina Properties
Two exploration targets that host rare-elementmineralization with anomalous Be, Rb, Cs, Nb, Sn and Ta contents havebeen identified on the Georgina Properties. Both exploration targetshave the potential to host lithium mineralization in the form ofspodumene. These exploration targets are Iris Lake and Parks Lake( Figure4 ).
Iris Lake Exploration Target
The Iris Lake exploration target was initiallyidentified by the presence of garnet muscovite aplite (sodium-richpegmatite) in the field. The potential to host rare-elementmineralization was confirmed by the assays of 7 samples with anomalousrare-elements around Iris Lake ( Table 1 ).
Table 1 shows the assays for the anomalous rare-elementpegmatite samples received to date on the Georgina Properties. Thesesamples all plot along an east-west pegmatite trend around Iris Lakeexcept for samples 965118 and 965119 ( Figure 4 ). Iris Lake is located 780 m north of Parks Lake, withexcellent road access using Camp 51 Road. Iris Lake is named after thewild iris flowers that grow along the shoreline. Tearlach’s geologyteam conducted additional sampling along strike of the Iris Lakepegmatite trend, and assays are pending.

Parks Lake Exploration Target
Following the discovery of sodium-rich andpotassium-rich pegmatites at Iris Lake, Tearlach staked open ground onParks Lake (see press release dated July 20, 2023). The assays aboveconfirmed the fractionated nature of Iris Lake and also Parks Lake(samples 965118 and 965119). According to the pegmatite deposit model,pegmatite melts fractionate from barren to Be to Be+Nb to Be+Ta+Lienrichment ( Figure 3 ). Thus, enrichmentin rare-elements (i.e., Be, Rb, Cs, Nb, Sn and Ta) indicates a strongpotential for lithium mineralization nearby. Tearlach geologists thenbegan mapping on Parks Lake using boat access. Outcrops are abundanton the islands within and along the shoreline of Parks Lake.

Dr. Selway, VP of Exploration, exclaimed that “ourfield geologists are on a Treasure Hunt for lithium mineralization andthe anomalous rare-element assays at Iris Lake and the discovery ofberyl and Nb-Ta-oxide minerals at Parks Lakes indicates that we areclose to discovering lithium mineralization. This reminds me ofOntario’s Operation Treasure Hunt Open File Report 6199 (2008), inwhich Fred Breaks and I found anomalous Rb and Cs in bulk rock samplesand beryl, Nb-Ta-oxide minerals and tourmaline in the Parks Lakearea”.

Sampling and MappingMethodology
As of Aug. 2, 2023, a total of 230 grab sample assayshave been completed and returned by Actlabs, Ancaster, Ontario,throughout the Georgina Stairs and Georgina East Properties from the2023 summer mapping program. Additional samples have assays pending.These grab samples cover all of the lithologies present on theProperties: granite, pegmatite, metasedimentary rocks and diabase.This assay database contains samples with anomalous rare-elements (Be,Rb, Cs, Nb, Sn, Ta), which are associated with lithium mineralization.
Quality Control
The grab samples were delivered by Tearlach geologiststo Actlabs, Geraldton or Thunder Bay preparation labs. Samples wereassayed by Actlabs, Ancaster analytical lab, which is an ISO 17025accredited laboratory. The samples were digested using lithiummetaborate/tetraborate fusion and assayed by ICP-OES and ICP-MS forwhole rock major oxides and trace elements (i.e., 4Litho-PegmatiteSpecial package). Li2O % was digested using sodium peroxide fusion andassayed using ICP-OES. Actlabs inserted standards, blanks, pulpduplicates and prep duplicates into the sample stream.
