OPERATIONAL (on a 100% basis unless otherwise noted)

• The beneficiation plant at the Juanicipio Project, which was recently energized following connection to the national power grid has commenced commissioning and full-scale ramp-up of milling activities. As reported by the operator, Fresnillo, the operation remains on track to reach nameplate production mid-to-late 2023. During this ramp-up period, excess mineralized material from the Juanicipio Project continues to be processed through the nearby Saucito and Fresnillo beneficiation plants (100% owned by Fresnillo) on available capacity basis.
  
  
• For the year ended December 31, 2022:
  
  • 646,148 tonnes of mineralized development and stope material were campaign processed through the Fresnillo and Saucito plants, with 8,697,372 payable silver ounces, 20,268 payable gold ounces, 4,487 payable lead tonnes and 6,758 payable zinc tonnes produced and sold;
  • average silver head grade for the year was 520 grams per tonne ("g/t"); and
  • pre-commercial production revenue (net of treatment and processing costs) totaled $215,736, less $61,985 in mining and transportation costs, and $20,913 in depreciation and amortization, netting $132,838 in gross profit by Juanicipio.
    
    

• For the three months ended December 31, 2022:

JUANICIPIO PROJECT UPDATE

Underground Mine Production

With the Juanicipio plant now in the commissioning and ramp-up phase, excess mineralized material from the Juanicipio Project continues to be campaign processed, subject to capacity availability, at the nearby Saucito and Fresnillo plants (both 100% owned by Fresnillo). Metals are refined and sold on commercial terms under long-term off-take agreements with an affiliate of Fresnillo. During the year and quarter ended December 31, 2022, approximately 63% and 70% respectively, of the total tonnage processed was through the Saucito plant. The Saucito plant flowsheet better resembles that of the Juanicipio flowsheet and will provide valuable metallurgical information as production ramps up at Juanicipio.

In the year ended December 31, 2022, a total of 646,148 tonnes of mineralized development and stope material were processed through the Fresnillo plants. The resulting payable metals sold and processing details are summarized in Table 1 below.

Table 1: Mineralized Material Processed at Fresnillo's Processing Plants (100% basis)

⁽¹⁾ Provisional revenues for 2020 were finalized in Q1 2021 resulting in negative adjustment to net revenue of $1,146.

⁽²⁾ The underground mine is now in stopes with mineralized development and stope material being processed through Fresnillo's plants and refined and sold. The mine was considered readied for its intended use on January 1, 2022.

In the three months ended December 31, 2022, a total of 165,786 tonnes of mineralized development and stope material were processed through the Fresnillo plants. The resulting payable metals sold and associated processing details are summarized in Table 2 below. The sales and treatment charges for tonnes processed in Q4 2022 were recorded on a provisional basis and will be adjusted in the first quarter of 2023 based on final assay and pricing adjustments in accordance with the offtake contracts.

Table 2: Mineralized Material Processed at Fresnillo's Processing Plants (100% basis)

⁽¹⁾ The underground mine is now in stopes with mineralized development and stope material being processed through Fresnillo's plants and refined and sold. The mine was considered readied for its intended use on January 1, 2022.

The average silver head grade for the mineralized development and initial stope material processed in the year and three months ended December 31, 2022 was 520 g/t and 415 g/t, respectively (year and three months ended December 31, 2021 was 470 g/t and 542 g/t, respectively). As per plan, and mine ramp-up, this increased grade for year 2022 reflects more stoped vein material being processed. Metal recovery and concentrate grades are in line with expectations from the initial metallurgical test work conducted on Valdecañas mineralized material.

Processing Plant Construction & Outlook

The Juanicipio Project team delivered the 4,000 tpd processing plant for commissioning in the fourth quarter of 2021. However, as previously reported, in late 2021, the Comisión Federal de Electricidad ("CFE"), a state-owned electrical company, notified Fresnillo that approval to complete the tie-in to the national power grid could not yet be granted and the mill commissioning timeline would therefore be extended. This delay primarily related to staffing effects related to the COVID-19 pandemic on the state-owned electrical company. To mitigate the effect on cash flow generation from the Juanicipio Project while CFE approvals were pending, Fresnillo made available unused plant capacity at its Saucito and Fresnillo operations to process mineralized material produced at the Juanicipio Project during this period, matching commissioning and ramp up tonnages that were previously expected, where possible. On December 28, 2022 the Company announced its receipt of CFE approval, the completion of the electrical tie-in to the national power grid and the envisioned commissioning of the 4,000 tpd processing facility. Commissioning commenced in early January 2023 with feed of lower grade mineralized material to the grinding mills. Mineralized material has been conveyed to the fine ore bin and stockpiled for commissioning and ramp-up operations. Processing of higher grade material is envisioned once the plant is fully commissioned and operating at steady state levels.

With the plant now in the commissioning and ramp-up phase, final project capital costs are expected to wind down as Juanicipio approaches full commercial production and associated free cash flow generation. Additional funding requirements related to market conditions, delayed ramp up to nameplate capacity, tax payments or additional sustaining capital in excess of the operating cash flow generated is expected to be funded by further cash calls required from Fresnillo and MAG.

FINANCIAL RESULTS – YEAR ENDED DECEMBER 31, 2022

As at December 31, 2022, MAG had working capital of $29,232 (December 31, 2021: $57,761) including cash of $29,955 (December 31, 2021: $56,748) and no long-term debt. As well, as at December 31, 2022, Juanicipio had a negative working capital of $1,395 including cash of $1,102 (MAG's attributable share is 44%).

The Company's net income for the year ended December 31, 2022 amounted to $17,644 (December 31, 2021: $6,025) or $0.18/share (December 31, 2021: ($0.06)/share). MAG recorded its 44% income from equity accounted investment in Juanicipio of $40,767 (December 31, 2021: $15,686) which included MAG's 44% share of net income from the sale of pre-production development and stope material as well as loan interest earned on mining assets brought into use (see Table 3 below).
