HIGHLIGHTS – DECEMBER 31, 2021 AND SUBSEQUENT TO YEAR END

OPERATIONAL

• Significant progress was achieved during the year ended December 31, 2021 on the construction of the 4,000 tonnes per day (“tpd”) Juanicipio processing plant as the Juanicipio project team delivered the project for plant commissioning late in the fourth quarter of 2021.

• The plant commissioning timeline was extended, however, by approximately six months until the regulatory approval to tie into the national power grid is obtained.  The plant commissioning timeline is now expected to commence in Q2 2022.

• As reported by the operator Fresnillo, the Juanicipio Project is expected to come in on budget with the processing plant expected to be ramped up to 85% to 90% of plant capacity by the end of 2022.

• A regularly updated photo gallery of construction progress at Juanicipio is available at https://magsilver.com/projects/photo-gallery/#photo-gallery.

• Campaign processing of mineralized material from development headings continues through the nearby Fresnillo plant and starting in Q4 2021 mineralized material also began to be campaign processed at Fresnillo’s Saucito plant. Saucito’s flowsheet better resembles that of the Juanicipio plant and will provide further valuable metallurgical benefits as production commences at Juanicipio.

• The campaign processing rate originally targeted at 16,000 tonnes per month increased significantly to an average of 37,983 tonnes per month in Q4 2021 and to an average of 44,963 tonnes per month for the first two months of 2022.

• Processing at the Fresnillo plants is expected to continue until the Juanicipio plant is commissioned, with Fresnillo making available any unused plant capacity at its Minera Fresnillo and Minera Saucito operations, and if possible matching commissioning and ramp up tonnages that were previously expected at Juanicipio.

• For the three months ended December 31, 2021, on a 100% basis:
  • 113,950 tonnes of mineralized material were campaign processed through the Fresnillo and Saucito plants, with 1,519,027 payable silver ounces, 3,641 payable gold ounces, 563 tonnes of lead and 800 tonnes of zinc produced and sold;
  • Average silver head grade was 542 grams per tonne (“g/t”); and
  • Pre-commercial production sales totaled $39,368 for the quarter (net of treatment and processing costs), less $7,593 in mining and transportation costs, netting $31,775 in gross profit by Minera Juanicipio in the quarter.

• For the year ended December 31, 2021, on a 100% basis:
  • 251,907 tonnes of mineralized material were campaign processed through Fresnillo’s plants, with 2,974,524 payable silver ounces, 5,975 payable gold ounces, 1,065 tonnes of lead and 1,519 tonnes of zinc produced and sold;
  • Average silver head grade was 470 g/t; and
  • Pre-commercial production sales of $75,393 (net of treatment and processing costs) less $15,329 in mining and transportation costs, netting $60,064 gross profit in Minera Juanicipio for the year.

• Since commencing campaign processing of Juanicipio mineralized material from development headings in August of 2020 through February 2022, a total of 413,691 tonnes of mineralized development material have been processed through the nearby Fresnillo plant and starting in December 2021 in the Saucito plant:
  • contributing cash-flow to offset some of the initial project capital; and
  • de-risking Juanicipio’s metallurgical performance, which is expected to significantly speed up project ramp-up.

• A further 89,925 tonnes of mineralized development material with a silver head grade of 529 g/t were processed in January and February 2022 through the Fresnillo and Saucito plants.

EXPLORATION

• Results of the Juanicipio 2020 exploration program were reported in the third quarter (see Press Release dated August 5, 2021), and the program successfully:
  • Confirms, and allows modeling with greater detail and confidence of the high-grade silver resource within the upper parts of the Valdecañas Bonanza Zone (as defined in the 2017 PEA) where the first several years of mining is expected to occur;
  • Confirms, expands, and allows improved modeling of the continuous wide mineralization of the Valdecañas Deep Zone (as defined in the 2017 PEA); and
  • Confirms, expands, and allows improved modeling of the ever-growing Anticipada Vein.

• The Juanicipio 2021 exploration program was completed in Q4 2021 with $6,296 spent on a 100% basis and was focused on continued step-out and infill drilling of the Valdecañas Vein System (including independent targeting of the Venadas Vein family and the Anticipada Vein).

• The Juanicipio 2022 exploration program is currently in process, with five drill rigs presently on surface running concurrently with continued underground definition and geotechnical drilling, and one rig testing the new Cesantoni target in the northwest part of the Juanicipio concession.

• Deer Trail Project in Utah:
  • Assays were released in Q3 2021 for the Phase I drill program (see Press Release dated September 7, 2021), which successfully fulfilled all three of its planned objectives by:
    • Confirming the presence of a thick section of more favorable carbonate host rocks (the predicted “Redwall Limestone” or “Redwall”) below the Deer Trail mine;
    • Confirming and projecting two suspected mineralization feeder structures to depth; and
    • Intercepting high-grade mineralization related to those structures in host rocks below what was historically known.
  • A follow up 5 hole/5,000 metre Phase II drill program commenced in Q3 2021 and is in process with all assays pending.

• Subsequent to the year end, the Company entered into a Definitive Arrangement Agreement with Gatling Exploration Inc. (TSXV:GTR, OTCOB:GATGF) (“Gatling”) pursuant to which the Company will acquire all of the issued and outstanding common shares of Gatling in an all-share transaction. The Company and Gatling have also entered into a loan agreement pursuant to which the Company has agreed to provide Gatling with a C$3 million secured convertible bridge loan to finance Gatling’s accounts payable and operating expenses.

LIQUIDITY AND CAPITAL RESOURCES

• As at December 31, 2021, MAG held cash of $56,748 while Minera Juanicipio had cash on hand of $18,972 on a 100% basis.

• According to the operator Fresnillo, the Juanicipio Project construction is expected to be delivered on budget at $440,000.

• With the current ramp up of underground mine production and given hiring restrictions on contractors arising from new 2021 labour reform legislation, the timing of various sustaining capital expenditures has been brought forward:
  • These sustaining capital costs are included in current Juanicipio development costs but are not considered by the operator as part of the $440,000 initial project capital; and
  • The costs incurred are expected to reduce future sustaining capital costs and totaled approximately $41,388 on a 100% basis in the second half of 2021 in preparation for the legislation to come into effect.

• The expected cash flow from the ongoing campaign processing until the Juanicipio plant is commissioned, along with the cash held by Minera Juanicipio at December 31, 2021 of $18,972, are projected to substantially fund the remaining capital expenditures in the $440,000 initial capex (a cash call has not been needed since mid-December 2021 which was $21,000 on a 100% basis).

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

• In Q4 2021, MAG closed a bought deal share offering and issued 2,691,000 common shares, including 15,700 common shares issued to an officer and two directors of MAG and 351,000 common shares issued upon the full exercise of the over-allotment option, at $17.15 per share for gross proceeds of $46,151. The Company paid commission of $2,301 to the underwriters and legal and filing costs totaled an additional $608 resulting in net proceeds of $43,242.

COVID-19

• Fresnillo, the Juanicipio operator implemented a range of safety measures and monitoring procedures, consistent with World Health Organization and Mexican Government COVID-19 directives.

• COVID-19 had an impact on the Juanicipio plant commissioning timeline however during the course of the year:
  • In Q1 2021, Fresnillo, as operator, reported that commissioning was pushed out a few months to Q4 2021 as some infrastructure contracts were delayed related to COVID-19; and,
  • In Q4 2021, approval to complete the tie-in to the national power grid was extended as noted above related to knock-on effects of the pandemic.

CORPORATE

• MAG continued to refresh its board during the year with three new appointments:
  • Ms. Susan Mathieu was appointed to the board on January 13, 2021 increasing the size of the board to eight members;
  • Mr. Tim Baker was appointed to the board on March 31, 2021 replacing Mr. Richard Clark who resigned from the board to focus on other professional responsibilities; and,
  • Mr. Dale Peniuk was appointed to the board on August 3, 2021 replacing Mr. Derek White who did not stand for re-election at the Company’s Annual General and Special Meeting on June 21, 2021.

• On October 16, 2021 MAG announced that Mr. W.J. (Jim) Mallory joined the Company as its Chief Sustainability Officer (“CSO”) highlighting the Company’s commitment to environmental, social, governance (“ESG”) betterment.

Mr. Di Trapani is a finance executive with experience in the natural resources sector spanning two decades, most recently having served as the Chief Financial Officer at Galiano Gold Inc. Mr. Di Trapani replaces Mr. Larry Taddei, who, after 12 years of service with the Company, will step down from the CFO role to pursue other opportunities. Mr. Taddei will assist in the orderly transition of his duties following Mr. Di Trapani’s appointment.

JUANICIPIO PROJECT UPDATE

Underground Mine Production

As of August 2020, mineralized development material from the Juanicipio Project is being campaign processed, refined and sold on commercial terms at a targeted rate through Q3 2021 of 16,000 tonnes per month at the nearby Fresnillo plant 12 kilometres away.  The processing rate increased to an average of 37,983 tonnes per month in Q4 2021 and subsequent to the year end to an average of 44,963 tonnes per month for the first two months of 2022. In December 2021, for the first time, 8,725 tonnes were processed at Fresnillo’s Saucito beneficiation plant (also 100% owned by Fresnillo).  The Saucito plant flowsheet better resembles that of the Juanicipio plant and will provide further valuable metallurgical information as processing commences at Juanicipio. This preproduction toll processing of Juanicipio mineralized development material plus some initial stope production is expected to continue until the Juanicipio plant is commissioned

In the three months and year ended December 31, 2021, 113,950 and 251,907 tonnes of mineralized development material respectively, 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 are summarized in Table 1 (three months ended December 31, 2021) and in Table 2 (year ended December 31, 2021) below.

Table 1: Q4 2021 Development Material Processed at Fresnillo’s Processing Plants (100% basis)

⁽¹⁾ Ounces (“oz”) for silver and gold and, pounds (“lb”) for lead and zinc.

Table 2: Year 2021 Development Material Processed at Fresnillo’s Processing Plants (100% basis)

⁽¹⁾ Ounces (“oz”) for silver and gold and, pounds (“lb”) for lead and zinc.
⁽²⁾ Processing of Juanicipio mineralized development material at the Fresnillo plant commenced in August of 2020, with no prior processing.
⁽³⁾ Provisional sales for 2020 were finalized in Q1 2021 resulting in negative adjustment to net sales revenue of $1,146.

The average silver head grade for the mineralized development material and initial stope material processed in the three months and year ended December 31, 2021 was 542 g/t and 470 g/t (three months and year ended December 31, 2020 was 300 g/t and 328 g/t) respectively. This increased grade in the last quarter of 2021 reflects less diluted development material and more stoped vein material being processed.

Processing Plant Construction & Outlook

The Juanicipio project team delivered the Juanicipio plant for commissioning in the fourth quarter of 2021.  However, according to the operator Fresnillo, 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 the projected commissioning timeline has therefore been extended by approximately six months, with commissioning of the Juanicipio processing plant now expected to commence in Q2-2022 with ramp up to 85 to 90% of the nameplate 4,000 tpd capacity by the end of 2022, according to Fresnillo.

In order to minimize any potential adverse economic effect of the revised commissioning timeline, Fresnillo has indicated it will make available any unused plant capacity at its Minera Fresnillo and Minera Saucito operations to process mineralized material produced at Juanicipio during this period, and if possible match commissioning and ramp up tonnages that were previously expected. The effect on cashflow generation from Juanicipio therefore will also be mitigated while power connection approvals are pending.

With the plant ready to commence commissioning once connected to the power grid, final construction costs are expected to wind down until final commissioning and testing commence.  Meanwhile, as noted above, the amount of mineralized development material being processed at the two Fresnillo plats since Q4 2021 has been significantly higher than the original targeted rate of 16,000 tonnes per month. The cash flow from this processing, along with the cash held by Minera Juanicipio at December 31, 2021 of $18,972 and the expected cash flows from continued processing until the Juanicipio plant is commissioned are projected to substantially fund the remaining capital expenditures in the $440,000 initial project capital (a cash call has not been needed since mid-December 2021 which was $21,000 on a 100% basis).

With the current ramp up of underground mine production and given hiring restrictions on contractors arising from new 2021 labour reform legislation, the timing of various sustaining capital expenditures has been brought forward.  Labour reform on subcontracting and outsourcing in Mexico was published on April 23, 2021 and came into effect on September 1, 2021.  With various restrictions on hiring contractors, Fresnillo, as operator, has indicated a need to internalize a significant portion of its contractor workforce and perform much of the development work directly rather than outsourcing it to contractors. This requires investment in equipment to be utilized in underground operations, either not previously in the project scope or not envisaged to be required until later in the mine life. As well, certain underground development expenditures related to processing development material and some small items brought forward from project investments planned in the future are considered sustaining capital by Fresnillo.  The costs incurred are expected to reduce future sustaining capital costs and totaled approximately $41,388 on a 100% basis in the second half of 2021 in preparation for the legislation to come into effect. These costs are included in the current Juanicipio development costs but are not considered by the operator as part of the $440,000 initial project capital. Should there be additional funding requirements in excess of the cashflow generated related to further commissioning delays or to additional sustaining capital that is being brought forward, there may still be further cash calls required from Fresnillo and MAG.

Juanicipio Exploration Update

The planned expenditures for the 2022 Exploration Program total $7,000 with the programs designed to expand and convert the Inferred Mineral Resources included in the Deep Zone into Indicated Mineral Resources, and to explore other parts of the Juanicipio concession.  All aspects of the exploration work continue to be done under strict COVID-19 protocols.  Subsequent to the year-end in mid-January, 2022, drilling began on the first hole on the “Cesantoni Kaolinite Pits”(Cesantoni) target (assay pending). Cesantoni lies in the northwestern corner of the Juanicipio concession, roughly 6 km west of the Valdecañas Vein and related underground and surface infrastructure.

The 2021 Juanicipio exploration program was completed in late 2021, with an actual spend of $6,296 on a 100% basis and was focused on continued step-out and infill drilling of the Valdecañas Vein System (including independent targeting of the Venadas Vein family and the Anticipada Vein). In total, 23 targets (holes) were successfully tested with 21 being deep infill holes and two exploration holes on other parts of the Juanicipio concession, resulting in 29,421 metres drilled.  The program results will be released in Q2 2022 pending receipt of all assays.

Assays for the Juanicipio 2020 drill program were released in the Q3 2021 (see Press Release dated August 5, 2021).  The 2020 drill program successfully:

• Confirmed, and allowed modeling with greater detail and confidence of the high-grade silver resource within the upper parts of the Valdecañas Bonanza Zone where the first several years of mining will occur;
• Confirmed, expanded, and allowed improved modeling of the continuous wide mineralization of the Valdecañas Deep Zone; and,
• Confirmed, expanded, and allowed improved modeling of the ever-growing Anticipada Vein.

DEER TRAIL PROJECT UPDATE

Phase I drilling commenced in November 2020 and was completed in Q2 2021 with assays and interpretations released in the third quarter of 2021 (see Press Release September 7, 2021). Phase I saw the completion of three holes and 3,927 metres drilled from surface and successfully fulfilled all three of its planned objectives by:

1. Confirming the presence of a thick section of more favorable carbonate host rocks (the predicted “Redwall Limestone” or “Redwall”) below the Deer Trail mine;
2. Confirming and projecting two suspected mineralization feeder structures to depth; and
3. Intercepting high-grade mineralization related to those structures in host rocks below what was historically known.

Phase II drilling commenced at the Deer Trail Project on August 20, 2021 and is in process, planned for 5,000 metres of drilling over 5 holes.  Deviation/directional drilling is being used in Phase II to make the drilling more efficient and accurate. In part to facilitate the directional drilling, drilling contractors were changed in Q1 2022, with the new contractor on site and preparing to resume drilling.

GATLING ACQUISITION

Subsequent to the year end, the Company entered into a Definitive Arrangement Agreement with Gatling pursuant to which the Company will acquire all of the issued and outstanding common shares of Gatling in an all-share transaction. The Company and Gatling have also entered into a loan agreement pursuant to which the Company has agreed to provide Gatling with a C$3 million secured convertible bridge loan to finance Gatling’s accounts payable and operating expenses.

Gatling is a Canadian gold exploration company focused on advancing the Larder Gold Project, located in the prolific Abitibi greenstone belt in Northern Ontario, Canada. The 3,370 ha Larder Project hosts three high-grade gold deposits along the Cadillac-Larder Lake Break, 35 km east of Kirkland Lake and 7 kilometers west of the Kerr Addison Mine. The project is 100% owned by Gatling and is comprised of patented and unpatented claims, leases and mining licenses of occupation within the McVittie and McGarry Townships. All parts of the Larder property are readily accessible and MAG expects to engage the existing exploration team going forward.
