Tearlach Reports Initial Gabriel Project Drill Results with Each Drill Hole intercepting grades over +1,000 PPM Lithium in Claystone and Thick Zones of mineralization

VANCOUVER, British Columbia, April 18, 2023 (GLOBE NEWSWIRE) — Tearlach Resources Limited (TSXV: TEA) (OTC: TELHF) (FRANKFURT: V44) (“Tearlach” or the “Company”) announce the rush assay results for the first set of five (5) out of the eleven (11) holes on the Gabriel Project Phase 1 drilling program. The drill holes contained broad mineralization zones, with intervals exceeding 1,000 ppm lithium and grades up to 1,460 ppm. The twinned drill holes showed grades up to 85% higher than the Blackrock Silver (“BRS”) program in the mineralized zones.

Assay Highlights:

Each of the five (5) drill holes encountered over 1,000 ppm lithium with thick zones of mineralization, with assays from six (6) drill holes pending.
The longest intercept of lithium mineralization for the five (5) holes is 146.6 feet – Hole – 009.
Highest primary intercept grade is 802 ppm Li over 61 feet – Hole – 018.
The highest grade for an “Included intercept” is 1,196 ppm lithium over 33.3 feet, including 1,460 ppm – Hole – 012.
Each hole returned multiple assay values (total of 15) > 1,000 ppm Li, with the highest value being 1,460 ppm.

Continuity:

Geological Continuity of claystone stratigraphy in all drill holes.
4.12 km² was drilled in this initial drilling campaign.
The reported drill core holes are within a general area of 1.5 kilometers x 2.75 kilometers.

Comparison with Previous Results:

The lithium intercepts confirm BRS’s discovery, and the Gabriel twin holes’ confirmation drilling yielded grades 40-85% higher than the corresponding Blackrock Silver holes.
The continued discrepancy between the TEA and BRS assays justifies a comprehensive re-assay program for BRS TN22 drill hole pulps, with results to be utilized in future resource estimation.
Bordering American Lithium Corp.’s TLC deposit, Gabriel shows similar lithium-bearing lithologic horizons and similar potential to host a significant lithium deposit immediately adjacent to a major highway, US95, and just outside of the town of Tonopah. There is no assurance that mineralization comparable in size or scale to that on adjacent properties will be discovered on Gabriel.

Note: Mineralization on adjacent or nearby properties is not indicative of mineralization on the Gabriel Project.

“This is a big step for Tearlach, from the joint venture’s inception to the first drill results within three months, and is a massive credit to the team. Not only have we confirmed the discovery, but our core drilling has established that the grade profile is substantially higher than previously discovered by BRS. These results, along with the wide-spaced step-out holes that remain to be reported, demonstrate the project’s high-grade and thick zone potential over a large area. American Lithium and American Battery Technology, also on the Tonopah lithium belt, have emerged as globally significant deposits. With Tearlach’s team seeing many similarities, Gabriel could quickly advance to a similar state of development with a resource planned by year-end,” Morgan Lekstrom, the CEO, explained. “The recheck assay program is a very simple solution developed in collaboration with our resource modellers and geologists that allow us to utilize the BRS program in our resource modelling, again low cost – high impact work.”

Results have been received for two (2) core holes that have been drilled to “twin” a Blackrock Silver rotary hole (the “TN22” holes). A zone of claystone-hosted lithium mineralization is present in both holes. The intercept grade for both holes is higher than the corresponding intercept for the Blackrock Silver-Drilled TN22 holes.

	Notes:	1) 400 ppm Li cut-off grade.
		2) No recovery intervals internal to an intercept assigned a grade of “ZERO.”
		3) The Gabriel core sample intervals closely, but not exactly, conform to the TN22 rotary sample intervals.

Analytical results for three (3) step-out Gabriel core holes have been received and reported as the following. Lithium mineralization in these three (3) holes is primarily hosted in laminated claystone and locally within gravel interbeds (see photo below).

Notes: 400 ppm Li cut-off grade. Assay results pending for GAB-018 downhole from 300 feet

It is encouraging that the lithium mineralization intersected in these holes expands the footprint of drilled mineralization into the western portion of the Gabriel property.

The core boxes below display the lithology and corresponding lithium grades for four (4) of the five (5) drill holes reported here, with each hole represented by one core box.

Assay Procedures:

The procedures utilized for handling the drill core and analysis of samples are as follows:

Core boxes transported daily from the drill rig to the BRS core logging facility in Tonopah, Nevada, by either the drill crew or TEA geologists,
Initial logging of the core conducted by the TEA geologists, including for rock type, percent recovery and rock quality,
Sample intervals marked,
Certified Reference Material (CRM) pulps, coarse blank, and blank pulps inserted into the sample set,
Photographed each box of core,
Core boxes transported from the Tonopah logging facility to the ALS Laboratory located in Reno, Nevada, by either ALS contracted drivers or by TEA geologic staff,
Core cut and sampled by ALS staff,
Samples dried, weighed, crushed, pulverized, and split by ALS,
Samples subjected to a 4-acid digestion and analyzed by ICP (ME-ICP61) by ALS,
Chain of custody and security maintained throughout the material handling and analytical processes.

TEA geologists have identified 650 samples (3,250 feet of drilling) from TN22 holes that are candidates for check assaying (re-assay pulps). The addition of this data to the GAB drilling dataset, at a low relative cost, will expand the extent of data around the perimeter of GAB holes and increase the density of data internal to the GAB drill pattern. A set of 28 intact core samples have been collected for bulk density measurement. The determinations will be conducted by the ALS Laboratory in Reno, Nevada. The bulk density values will be directly utilized for resource model calculations.
