VANCOUVER, British Columbia , April 11, 2023 (GLOBE NEWSWIRE) — Tearlach Resources Limited (TSXV: TEA) (OTC: TELHF) (FRANKFURT: V44) (“Tearlach” or the “Company”) is pleased to announce that a second large land package has been staked in the Georgia Lake area adjacent to Georgina Stairs. The new property, Georgina East, comprises 500 cell claims and is located near Jellicoe and Beardmore, northwestern Ontario. The claim block has an area of 10,580 hectares and measures approximately 17 km by 10 km. Georgina East property is 100% held by Tearlach.

Georgina East Property Highlights:

• Same geology as Georgia Lake pegmatite field.
• High Potential for the muscovite granite to be the parent to lithium pegmatites on the Georgina East property.
• Deep-seated regional structures as fluid pathways for pegmatites.
• Most of the Georgina East property is unexplored and near the Georgia Lake pegmatite field.
• Roads connect the Georgina East property to the Trans Canada Highway #1.

“After Dr. Selway identified the map was cut off and the geophysical anomalies matching Georgia Lake, we expanded our land claim package to become one of the largest land packages in the area. Not only is this project underexplored, but it also provides a potential discovery value add for mere staking costs. Another high impact, low-cost credit to Dr. Selway and the team,” states Morgan Lekstrom, CEO.

Technical Information:

Georgia Lake pegmatite field consists of multiple spodumene pegmatites, with the first discovery of spodumene (Li mineral) in 1955. The Georgia Lake spodumene pegmatites are hosted by the metasedimentary rocks near the muscovite granites and diabase dykes and sills. The Ontario regional bedrock geology map (MRD126) indicates that the property is mostly metasedimentary rocks, but this is likely an oversimplification as this area has not been mapped in detail and was not covered by Pye’s 1964 map (OGS M2056). Four sets of north-south trending Marathon diabase dyke (2.1 Ma) crosscut the Georgina East property, indicating regional deep-seated structures. According to Pye’s map, Rock Tech Lithium’s Nama Creek and Conway spodumene pegmatites are hosted by metasedimentary rocks crosscut by two N-S trending diabase dykes.

A northeast-trending topographic high occurs along the north shore of Leopard Lake and extends from one corner of the Georgina East property to the other corner. This NE-trending topographic high parallels the northeast-trending muscovite granite located immediately south of the Georgina East Property. The spodumene pegmatites in the Georgina Lake pegmatite field are commonly either NE or N-S trending, as per Pye’s map.

The Georgina East property’s geology shows many similarities with Rock Tech Lithium’s Georgia Lake Project, located 23 km east of Rock Tech’s spodumene pegmatites. The geology is the same as Balkan Mining and Minerals Limited’s Gorge Lithium Project and is located 4.7 km north of their spodumene pegmatites.

The Georgina East property is underexplored because it is located just off, E.G. Pye’s Georgia Lake Area map (Ontario Geological Survey, M2056, 1964), which has guided lithium pegmatite exploration in the area for many decades. Recorded historical exploration on the Georgina East property consists of drilling in 1972 and 1973 in search of sulphides and prospecting in 2009 and 2011. Most of the property has had no historical exploration despite being close to the Trans Canada Highway.

Georgina East has good infrastructure to support exploration as roads connect the property to the Trans Canada Highway #1. Leopard Lake Road and Camp 51 Road and multiple trails connect the property with the Trans Canada Highway to the north of the property. Trails also link adjacent properties, Georgina Stairs and Georgina East. Equinox Gold/Orion Mine Finance’s Greenstone Gold Mine, Geraldton, is about 34 km northeast of the Property. The town of Jellicoe is 14 km to the north, Beardmore is 22 km to the northwest, Nipigon is 65 km to the south, and Thunder Bay is 150 km to the southwest. Thunder Bay is a transportation hub with a deep-water harbour for shipping on Lake Superior, railway and Trans Canada highways going east and west across Canada, and a highway south to the United States.
