The project is being investigated for lithium mineralization found within spodumene pegmatites and is situated 9 km east of Rock Tech Lithium’s Georgia Lake Project.
Highlights:
- In the spring of 2023, data on the project area’s topography, geology, and geophysics were collected and used to pinpoint specific exploration prospects in the region.
- Outcrops, access roads, and logged areas were located using satellite images.
- 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.
On the Georgina Stairs claim block, 20 granite outcrops hosted by biotite metasedimentary rocks have been found by Tearlach’s geology team, contrary to what the Ontario Regional Geology Map (MRD126) previously claimed.
The claim block’s southernmost region has outcrops of medium- to coarse-grained biotite granite. The mapping data have been analyzed, and three (3) exploration target locations for more mapping have been identified.
Since pegmatite dykes are produced from granite, the discovery of granite is significant. For instance, the metasedimentary rocks hosting the spodumene pegmatites found at Rock Tech are located next to granites.
In May, 172 sample locations were identified, of which 76 samples were sent to Actlabs’ Geraldton location for analysis. Results are still pending. Granite samples are among the samples, and their rare-element content, as well as metasediments’ rare-element metasomatism—a potential sign of blind pegmatites—are examined.
Diabase was also sampled to identify between various sill and dyke generations and determine whether one generation is connected to pegmatites. To identify which direction these rare elements are increasing, the Li, Rb, Cs, Nb, Ta, and Be content of the granite will be displayed on a map. This is the direction in which to look for the existence of pegmatites.
There are numerous logging trails on the land, and access from the Peck Lake Road, which runs through the center of the property from north to south, has made prospecting easier. The truck was allowed to be parked close to the outcrops for the geology team.
The project is underexplored in part because it lies outside the boundaries of E.G. Pye’s map of the Georgia Lake Area (Ontario Geological Survey, M2056, 1964), which has served as a guide for exploration of the region’s lithium pegmatite deposits for many years.
Despite being so close to the Trans Canada Highway, the majority of the property has never been explored historically. Drilling for sulfides in 1972 and 1973 and prospecting for sulfides in 2009 and 2011 make up the property’s scant historical exploration.
The property lies 9 km east of Rock Tech Lithium’s spodumene pegmatites and shares geological similarities with Rock Tech’s Georgia Lake Project. The Gorge Lithium Project of Balkan Mining and Minerals Limited, which is situated 4.7 km north of their spodumene pegmatites, shares the same geology.
I am pleased to finally get into the field to look at the rocks on the Georgina Stairs Property. Tearlach staked the property in February 2023. The discovery of granite on the property is a good first step to finding pegmatites.

Tearlach welcomes Aboriginal Consultation and has organized face-to-face meetings for April 20th and 21st, 2023, with four First Nation communities with traditional territories on the Georgina Stairs Property: Animbiigoo Zaagi'igan Anishinaabek, Bingwi Neyaashi Anishinaabek, Biinjitiwaabik Zaaging Anishinaabek, and the Red Rock Indian Band.
Following these sessions, the four communities signed a Memorandum of Understanding on May 9th, 2023. Since he has extensive knowledge of and expertise with hunting and fishing in our project region, Tearlach has also employed a member of the First Nation communities as a geological assistant to join the geology team.
