Snapshot	Stornoway has not published 2019 and 2020 annual reports by the time it was delisted from TSX in September 2019. On October 27, 2023, Stornoway announced the suspension of operations at its Renard mine. Renard mine has been placed in a "Care and Maintenance" phase. Stornoway has also begun the process of placing itself under the protection of the Companies' Creditors Arrangement Act. In April 2024, Winsome Resources acquired an option to purchase the Renard Mine. During the option period Winsome will confirm the feasibility of repurposing Renard for lithium production, as well as determining the optimal transaction structure for the acquisition. In September 2024, Winsome announced the results of the Adina Lithium Project Scoping Study, based on the scenario of mineralised material being mined at Adina and transported to the Renard operation for processing.

Deposit type

• Kimberlite

Summary:

The Renard kimberlites were emplaced into granitic and gneissic host rocks, and contain diamonds of economic interest. The bodies comprise a late Neo-Proterozoic to Cambrian kimberlite field in Québec (Girard, 2001; Moorhead et al., 2002; Letendre et al., 2003).

To date, nine kimberlite pipes have been identified over a 2 km2 area in the Renard Cluster (Renard 1 to Renard 10; with Renard 5 and Renard 6 forming one body, referred to as Renard 65). The kimberlite pipes are typically spaced between 50 m and 500 m from each other. Geophysical data and drill information from delineation and bulk sampling programs indicate that, in general, most of the Renard kimberlites are irregular and elliptical in plan view. Surface areas of the kimberlite portion of the pipes range from 0.1 ha to 2.0 ha. Two laterally extensive kimberlite dyke systems, known as the Lynx and Hibou dykes, have been identified to the west and northwest of the pipe cluster, respectively. Portions of both dykes are included in the mineral resource estimation. Additional dyke like kimberlites have been discovered elsewhere on the property. These are not included in the mineral resource estimation but may warrant additional work at a later date.
