GALENA MINING LTD. announced that the construction progress at its Abra Base Metals Mine ("Abra" or the "Project") has reached 97% complete as of 30 November 2022. Processing plant commissioning is progressing quickly with practical completion now expected in December 2022. Ore currently being mined from underground is being stockpiled in readiness for processing to begin in January 2023.

Concentrate production will commence January 2023. Update on Abra Project progress: Overall progress continues as planned, with first concentrate production expected in First Quarter CY2023, following ore commissioning in January 2023. Practical completion of the processing plant is now expected ahead of schedule in December 2022.

The processing plant engineering, procurement and construction has reached 99% complete. Piping and electrical works have made significant progress and at the end of November were 96% and 92% complete, respectively. Mechanical items installation is almost complete at 99%.

In November, the first material was crushed and screened as part of the staged commissioning process. The crushing plant ran at design capacity and all commissioning milestones were successfully achieved. Dry commissioning also progressed in most areas of the plant including water and air services, tailings and concentrate thickening, grinding and reagents.

Dry commissioning of the remaining areas will be completed in December. Water commissioning commenced in the tailings and concentrate thickening areas of the plant and the remaining areas are expected to be wet commissioned by the end of December. Underground development continued during November with a new record of 462m being achieved over the month.

Development was focussed on the 1290mRL mine services area and the mining of the first 60m of ore drives. A total of 9,000t of ore has been stockpiled on the ROM pad in preparation for ore commissioning and start-up in January 2023. The decline has reached 1,276mRL which is 274m below the surface and 37m below the original top of the orebody (1313mRL).

Underground drilling has continued to consolidate the mining areas planned and has confirmed mineralisation up to 1330mRL. During December several ore drives will commence on the 1285 and 1300mRL levels which is expected to deliver the required ore for plant commissioning in January. Grade control and infill diamond drilling continued during November and 34 new holes were completed for a total of 4,338m.

To date, 16,243m of underground drilling has been completed. Assays received in November continue to build on the confidence in the geological interpretation of what is an extremely exciting and technically interesting mineralised system. Work continues on the evaluation of the results and mine plans and designs are being continually reviewed as part of the mining execution plans.
