2021 Operations Review

This year was dedicated to sustaining the operational improvements, methods, and capabilities realized during 2020. A number of new hires occurred during 2021, boosting the Zgounder workforce by more than 30%. Procedures, processes, mining and work methods continued to be refined and resulted in an average throughput of 716 tpd in Q4-2021, higher than the 670 tpd nameplate capacity of the two combined processing plants. Silver production in Q4-2021 reached 433,742 oz. For the year, the Corporation produced a record total of 1,600,646 Ag oz, a 120% increase from 2020.

The Corporation significantly changed its mining operations at Zgounder by moving from a shrinkage-stope mining method to a cut-and-fill method. Furthermore, increased mechanization began in 2021 with the introduction of the mine's first jumbo. The focus at the mine is on training employees in the new methods, equipment and tools as the Corporation scales up towards 2,700 tpd to support the planned expansion.

Capital Projects

Many capital infrastructure projects were completed in 2021 including a complete overhaul of the on-site roads, base camp, administrative buildings, electrical grid, on-site communications, surface water management, water retention and tailings facilities. A new assay lab was built and fitted with modern equipment, allowing the Corporation to double analysis capacity. Construction of the 60,000m³ water retention basin was completed, and filling of the basin began in March 2022.

The year also saw the completion of multiple mine and mill capital projects including refurbishment of the cyanidation plant, construction of a new underground explosive depot and the construction of two new mine portals. During Q4-2021, a new cone crusher at the flotation plant was installed and commissioned, which generated a 15% increase in throughput and a global milling rate of 716 tpd for the quarter.

Positive Feasibility Study for Zgounder

We announced a positive FS in February 2022 to expand the Zgounder Silver Mine from 700 tpd to 2,700 tpd capacity.

Highlights of the 2,000 tpd Expansion FS:

• Robust project economics (base case at $22/oz Ag):
• Before-tax 5% net present value ("NPV"): $471 million
• Before-tax internal rate of return ("IRR"): 57%
• After-tax 5% NPV: $373 million
• After-tax IRR: 48%
• Payback period: 1.7 years
• Initial life of mine of 11 years
• Increased throughput expected to drive annual Ag production to 7.9Moz by 2024
• Annual revenue expected to increase from $34 million in 2021 to $172 million by 2024
• LOM all-in sustaining cost ("AISC")¹ of $9.58/oz
• Low initial capital expenditures: $139.4 million, including $16.6 million in contingency cost
• First Ag pour planned in Q1-2024
• Further optimisation opportunities:
• Exploration along strike and at depth
• Potential to optimise the flow sheet during the front-end engineering design and the mine plan as part of the underground expansion
• Enhanced ESG plan: Reduction in water consumption and carbon emissions intensity

Zgounder Milestones

• Complete front-end engineering design in Q2-2022
• Construction start-up in Q3-2022
• New plant first Ag pour by Q1-2024
• Ongoing exploration with the aim of increasing reserves and resources and enhancing economics

2021 Successful Exploration Program

Zgounder

In 2021, a total of 55,449m of drilling was completed at Zgounder. The 2021 drill program had two objectives: increase the confidence level of the exploration target area identified in March 2021, and further extend mineralization in the eastern part of the deposit. The Corporation succeeded on both counts, extending the mineralized east-west strike from 775m to 1,100m in length and at depth. In December 2021 the Corporation published a resource update for the Zgounder deposit. Zgounder remains open with potential to expand existing resources at depth to the granite and through strike extensions to the east. Additional work will be completed to determine possible extensions to the west.

The updated mineral resource estimate incorporated 516 new drill holes (surface and underground combined) for 41,932m carried out on Zgounder between January and September 10, 2021. The mineral resource estimate formed the basis of the Corporation's maiden mineral reserve estimate in conjunction with the FS for the expansion of the Zgounder from 700 tpd to 2,700 tpd.

Further to the updated resource estimate, the FS reported by the Corporation in February 2022, included inaugural mineral reserves that were estimated by DRA Global Limited ("DRA") in accordance with the CIM Definition Standards for National Instrument 43-101 reporting. The Inferred material within the pit design was treated as waste.

Imiter bis

In 2021, the Corporation's initial fieldwork program on the Imiter bis project identified a north-south structure extending over four kilometers long. A drill exploration program was subsequently carried out consisting of 33 diamond drill ("DDH") for a total of 4,381m over four target areas (South Zone, Middle Zone, Northeast Zone, and Central Zone).

The geology and preliminary results indicate the presence of a low to neutral sulphidation Au-Ag epithermal system. The vein system of the main 4km structure is located close to a major contact between granodiorite and a wide mafic dyke. The 2021 drill exploration program confirmed continuity at depth with increasing widths in the Middle Zone. Preliminary results confirm the presence of both Au and Ag in the system. Hole IM-DD21-014 intercepted 1.8 g/t Au and 40.0 g/t Ag over 2.2m (part of a wider vein system intercepting 0.9 g/t Au and 19.6 g/t Ag over 8.8m). This intersection is located on the northern-most section drilled in the Middle Zone.

2022 Expanded Exploration Program

An initial exploration program of $14 million has been set for 2022 for a total of 72,500m of drilling. Of these 72,500m, 22,500m of DDH will be completed on the Zgounder mining permit and 7,500m of RC drilling will be conducted on the Zgounder regional permits. The 22,500m drilling program will focus on designed to expand existing resources at depth and test strike extensions to the east.

The 10,000m DDH program scheduled at Imiter bis in 2022 will test new prospective areas defined by the airborne survey and follow-up on the Q4-2021 drill results.

At Boumadine, an initial 7,500m drill exploration program has been established to test priority areas identified by the spectral survey and historical drilling. These areas will be enhanced by targets generated by the upcoming airborne geophysics.
