For 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. |

Summary:
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 desc ........

Summary:
The Abcourt-Barvue measured and indicated resources along the mineralized structure span a distance of 2 230 m (1 080 m west of the shaft in an E-W direction, and 1 150 m east of the shaft in a S49°E direction). The dip is 75° to 90° to the north.
In the Barvue sector, the ore lies in the south wall of the old pit, at its eastern extremity and below the current pit floor (at a depth of 76 m) to a maximum depth of 240 m. The mining proposal for Barvue includes deepening the pit to a depth of 166 m from surface and underground mining of the remaining resource.
In the Abcourt sector it is proposed to mine the upper part of the ore body by open pit to a maximum depth of 72 m. Mining will proceed underground under the pit using the Avoca cut- and-fill method to a depth of 150m to 200m with trackless equipment. Three declines will access the underground operation; the west, the central, and the east decline.
Open pit mining will be carried out using conventional truck and shovel method. Drilling will be performed by in-the-hole production drills. Blasting operations will use an emulsion ANFO (ammonium-nitrate fuel oil) explosive and a non-electric delay initiation system. An hydraulic shovel and a front-end loader will be used to load rigid haulage trucks.
For most of the open pit tonnages, haulage trucks will exit from Abcourt and Barvue pits onto a common haul road approximately 500m west of the mill site. Waste rock will be hauled to t ........
