GEORGIA LAKE PROJECT

Rock Tech Lithium owns spodumene-bearing pegmatites in the Georgia Lake area, located less than 200 kilometers northeast of the city of Thunder Bay, Ontario. The lithium bearing deposits form an integral part of the integrated converter strategy planned by the company.

Lithium mineralization was discovered in 1955 and subsequently explored by several historic owners. RockTech acquired the licenses since 2009 and carried out several drill campaigns until 2017. Based on a  total of 351 drill holes with a combined length of 47,384 m an NI43-101 compliant resource estimate of 6.58 million tonnes in the measured and indicated category and 6.72 million tonnes in the inferred category was published in August 2018 and is included in a Technical Report titled, "NI 43-101 Technical Report, Mineral Resource Estimation, Upgrade 2018, Georgia Lake Lithium Properties Beardmore, Ontario, Canada." Karl-Stephan Peters, EurGeol 787 Senior Geologist and Florian Lowicki, SACNASP 400425/13 are the Qualified Persons for the Technical Report and are independent of Rock Tech Lithium Inc. Report without Annexure. For the full report, please visit our SEDAR profile.

In 2018 Rock Tech engaged DMT for the preparation of a Preliminary Economic Assessment (“PEA”) which was published in October 2018. The following key outcomes are included in a Technical Report titled, "NI 43-101 Technical Report on the Preliminary Economic Assessment, Georgia Lake Lithium Properties Beardmore, Ontario, Canada." Keith McCandlish, P. Geol, P. Geo, FGC, FEC (Hon) and Karl-Stephan Peters, EurGeol 787, are the Qualified Persons for the Technical Report and are independent of Rock Tech Lithium Inc.

Table 2: NI43-101 PEA results based on aspodumene price of USD 827/t, October 2018

The PEA is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

To develop the project towards feasibility stage the company submitted the Project Definition and Notice of Project Status (“NoPS”) in August 2020. It has been confirmed that no Federal Impact Assessment is required since the production profile of Georgia Lake mine will be below the threshold. Further the status change from“Undeveloped Lands/Past Producer’ to ‘Mine Production and Development’ has been accepted, subject to the completion and acceptance of a certified comprehensive closure plan.
