SnapshotFor the Abcourt-Barvue deposit, management reviewed its strategic objectives and decided to focus its resources on developing its gold properties. This change implies an impairment loss for these assets. The Company has determined that the recoverable amount of this equipment is nil given the equipment's obsolescence and management's intentions. An amount of $2,819,832 has been recognized as of June 30, 2022, as an impairment loss for these assets.

On the Abcourt-Barvue property, the volcanic sequence is represented by the Figuery Group which is bounded to the north by the Amos Group and to the south by the Landrienne Group. The Abcourt-Barvue deposit and related base metal occurrences are located in the Figuery Group.

The Abcourt-Barvue mineralized horizon strikes E-W in the western portion of the property. In the Abcourt shaft area, the mineralized horizon changes its strike from E-W to SE-NW in the Barvue portion of the deposit. On the property, the units have steep (75°) dips to the north with a well-developed E-W regional schistosity. The stratigraphic tops for these units have been documented in the field as being to the north.

The Abcourt-Barvue mineralized zone has a thickness ranging from 2 to 30 metres. The deposit has a known east-west strike length of 2.2 km. Mineralization has been delineated by diamond drilling to a maximum vertical depth of 425 m below the surface. Mineralized horizons are dipping at 75° to the north.

Zinc and silver are the main metallic constituents of the Abcourt-Barvue deposit and these metals are associated with sphalerite, native silver and argentite. The presence of some gold and copper has been observed. Gold is usually associated with silver and copper occurs mostly at the eastern limit of the Barvue deposit.

The main mineralization which is mostly made up of disseminated and bedded sphalerite and pyrite (up to 10% of the rock) is described as:

- iron-poor, honey brown and dark colour sphalerite (ZnFeS2), finely disseminated in the tuff agglomerate horizons concentrated generally to the north of the marker bed, with additional mineralization in the marker bed and in the shear zone;
- 1-2% disseminated pyrite (some encompassed within the sphalerite);
- minor galena (PbS), chalcopyrite (CuFeS2), native silver (Ag) and proustite (Ag3AsS3).

The thickness of the mineralized horizon tends to increase eastward, most of the sulphides being located in the Barvue area. Generally speaking, we can observe a zinc enrichment in both footwall and hanging walls of the mineralized zone which are generally separated by lower grade marginal material. These two sub-parallel zinc-enriched units are currently known over a total length of 2.2 km to a vertical depth of 600 metres.

The Abcourt-Barvue silver-zinc deposit is classified as disseminated volcanogenic sulphide deposit. It shares numerous similarities with the Mattabi-type volcanogenic sulphide deposit. The zinc and silver sulphides mineralization is composed of disseminated and bedded sphalerite and pyrite found in close association with felsic volcanoclastic rocks.
