VANCOUVER, Nov. 14, 2022 - MAG Silver Corp. (TSX / NYSE American: MAG) ("MAG", or the "Company") announces the Company's unaudited financial results for the three months ended September 30, 2022. For details of the unaudited condensed interim consolidated financial statements and Management's Discussion and Analysis for the three months ended September 30, 2022, please see the Company's filings on SEDAR (www.sedar.com) or on EDGAR (www.sec.gov).

All amounts herein are reported in $000s of United States dollars ("US$") unless otherwise specified.

KEY HIGHLIGHTS

• MAG reported net income of $8,227 or $0.08 per share for the three months ended September 30, 2022 (net loss of $2,280 or ($0.02) per share for the three months ended September 30, 2021).
  
  
• As at September 30, 2022, MAG held cash of $39,507 and Juanicipio had cash on hand of $18,176.
  
  
• The Sustainalytics ESG risk rating for MAG improved 27% to 33.5 from 46.0, over the last twelve months. Since the initiation of Sustainalytics coverage of MAG in April 2019 the overall score has improved by 46%.
  

Operational - Juanicipio owned 44% by MAG

• Fresnillo continues to make available excess processing plant capacity at its nearby Saucito and Fresnillo operations. Campaign processing of mineralized material from development headings and stopes continues through these facilities and is expected to continue until the Juanicipio plant is commissioned.
  
  
• For the three months ended September 30, 2022, on a 100% basis:
  
  
  • A record 180,808 tonnes of mineralized development and stope material were campaign processed through the Fresnillo and Saucito plants, with 2,425,256 payable silver ounces, 4,901 payable gold ounces, 1,347 payable lead tonnes and 2,038 payable zinc tonnes produced and sold;
    
    
  • Average silver head grade for the quarter was 513 grams per tonne ("g/t"); and
  • Pre-commercial production sales (net of treatment and processing costs) totaled $49,715 for the quarter, less $18,127 in mining and transportation costs and $6,376 in depreciation and amortization charges, netting $25,212 in gross profit by Juanicipio.
    
    
• At the end of the quarter, Juanicipio held cash balances of $18,176 down from $37,504 at the end of Q2 impacted by lower margins as a result of lower metal prices, marginally lower head grade and ongoing capital expenditures.
  
  
• As reported by the operator Fresnillo, electrical commissioning of the processing plant is expected in the coming weeks.
  
  
• Campaign processing benefits include the cash flow being used to offset some of the initial and sustaining capital, and the de-risking of Juanicipio's metallurgical performance which is expected to significantly speed up project ramp-up.
  
  
• Approximately 70% of the tonnes processed in Q3 2022 were processed at the Saucito plant, where the flowsheet more closely resembles that of the Juanicipio plant. It is expected these results will provide further valuable metallurgical benefits when milling production commences at Juanicipio.
  
  
• Metal recovery and concentrate grades continue to fall in line with expectations from the initial metallurgical test work conducted on Valdecañas.
  

Corporate

• On October 5, 2022, MAG published its inaugural Sustainability Report underscoring MAG's ongoing and fundamental commitment to transparency with its stakeholders while providing a comprehensive overview of the Company's ESG commitments, practices, and performance for the 2021 year.
  

EXPLORATION

• The Juanicipio 2022 exploration program is currently in progress with five drill rigs on surface running concurrently with continued underground definition and geotechnical drilling, and one rig testing the new Los Tajos target (previously known as the Cesantoni target) in the northwest part of the Juanicipio concession.
  
  
• MAG has initiated a comprehensive data review and drilling campaign on the acquired Larder Project. The drilling program is focused below and lateral to the previously identified mineralization.
  
  
• The Deer Trail Project 5,000m Phase II exploration program is in progress with one drill and all assays pending.
  
  
• During the nine months ended September 30, 2022, the Company recorded a write down of $10,471 on its option earn-in project on a prospective land claim package in the Black Hills of South Dakota.
  

LIQUIDITY AND CAPITAL RESOURCES

• The expected cash flow from the ongoing campaign processing until the Juanicipio plant is commissioned, along with the working capital held by Juanicipio at September 30, 2022 are projected to substantially fund remaining capital requirements at Juanicipio (a cash call has not been needed since mid-December 2021 which was $21,000 on a 100% basis).
  

"In anticipation of the commencement of milling operations at Juanicipio, Q3 continued the trend of strong operational performance with record milling at the Saucito and Fresnillo operations, delivering over 2.4 million payable silver ounces. This brings our year-to-date payable silver production to over 6.8 million ounces" said George Paspalas, MAG's President and CEO. "As reported by Fresnillo to us, electrical commissioning is expected in the coming weeks and a target ramp-up to 85-90% of nameplate capacity is envisioned within months of commissioning. Juanicipio is well positioned to take its place as a significant and responsible silver producer whilst we continue to progress our exciting exploration programs at Juanicipio, Deer Trail and Larder."

JUANICIPIO PROJECT UPDATE

Underground Mine Production

In Q3 2022, a total of 180,808 tonnes of mineralized development and stope material were processed through the Fresnillo plants, realizing commercial and operational de-risking opportunities for the Juanicipio Project. The resulting payable metals sold and processing details on a 100% basis for Q3 2022 are summarized in Table 1 below. The sales and treatment charges for tonnes processed in the quarter were recorded on a provisional basis and will be adjusted in the fourth quarter of 2022 based on final assay and pricing adjustments in accordance with the offtake agreements.

Table 1: Q3 2022 Mineralized Material Processed at Fresnillo's Processing Plants (100% basis)

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

The average silver head grade for the mineralized development and initial stope material processed in Q3 2022 was 513 g/t (Q2 2022 567 g/t).

Processing Plant Construction & Outlook

The Juanicipio project team delivered the 4,000 tpd processing plant for commissioning in the fourth quarter of 2021. However, according to the operator Fresnillo and as previously reported, the state-owned electrical company (Comision Federal de Electricidad "CFE"), notified Fresnillo late in December 2021 that the regulatory approval to complete the tie-in to the national power grid could not yet be granted and that the Juanicipio plant commissioning timeline was therefore extended. As reported more recently by the operator Fresnillo, commencement of electrical commissioning of the Juanicipio processing plant is expected to occur in the coming weeks. It is expected that the plant will ramp up to 85-90% of the nameplate 4,000 tpd capacity within months of commissioning.

Should there be additional funding requirements related to further commissioning delays or to additional sustaining capital that is being brought forward in excess of the cash flow generated prior to attaining commercial production, there may still be further cash calls required from Fresnillo and MAG.

FINANCIAL RESULTS - THREE MONTHS ENDED SEPTEMBER 30, 2022

As at September 30, 2022, MAG had working capital of $42,434 (June 30, 2022: $47,673) including cash of $39,507 (June 30, 2022: $44,655) and no long-term debt. As well, as at September 30, 2022, Juanicipio had working capital of $9,954 including cash of $18,176 (MAG's attributable share is 44%).
