NEWS RELEASE

Discovery Reports Q3 2022 Financial Results and Update

November 24, 2022, Toronto, Ontario - Discovery Silver Corp. (TSX-V: DSV, OTCQX: DSVSF) ("Discovery" or the "Company") is pleased to announce its financial results for the three months ended September 30, 2022 ("Q3 2022") and provide a summary of key events for the quarter, and subsequent to quarter-end. All amounts are presented in Canadian dollars ("C$") unless otherwise stated.

Discovery's flagship project is our 100%-owned Cordero silver project ("Cordero" or the "Project") located in Chihuahua State, Mexico. Following the completion of a Preliminary Economic Assessment ("PEA") in 2021 that demonstrated Cordero is a large-scale,high-margin asset with a long mine life, our focus now is the delivery of a Pre-Feasibility Study ("PFS") on the Project in early 2023.

HIGHLIGHTS FROM Q3 2022 & SUBSEQUENT EVENTS:

• The Company released its 2021 Environmental, Social and Governance ("ESG") Report during the quarter and subsequent to quarter end received its official ESR Distinction, which is issued by the Mexican Center for Philanthropy to organizations that have demonstrated they operate in a socially and environmentally responsible manner, and its Great Place to Work Certification, which recognizes companies that create an outstanding employee experience through building a workplace culture of trust, credibility, respect, pride and collaboration.
• Results from the PFS metallurgical testwork program highlighting the exceptional metallurgical performance at Cordero with recoveries typically ranging from 90-95% for Ag, Pb and Zn from the tests completed so far. On average recoveries came in higher than what was assumed in our PEA and were achieved at significantly reduced reagent consumption highlighting the potential for reduced operating costs in the PFS.
• Phase 2 drilling, consisting of close to 80,000 m in over 250 drill holes, was completed in the quarter. Drill results will be used to support the upcoming PFS. Recent highlight results include 388 g/t AgEq over 33 m intercepted more than 700 m outside the current resource and 201 g/t AgEq over 42 m approximately 20 m below the resource pit shell.
• Discovery's balance sheet remains exceptionally strong with a cash and cash equivalents balance of $55 million and no debt as at September 30, 2022.

LOOKING AHEAD:

Tony Makuch, Interim CEO, states: "We recently wrapped up our Phase 2 drill program with results exceeding expectations. Of note, mineralized intercepts at depth and to the northeast highlight the potential to expand the size of the open pit in our upcoming PFS. The additional drilling should also further increase the confidence of the underlying resource estimate with the supporting drill dataset now consisting of close to 300,000 m of drilling in over 730 drill holes.

We also completed our PFS metallurgical test program in the quarter which demonstrated improved metallurgical recoveries at a very coarse grind size and significantly lower reagent consumption. This has allowed for an improved process design with metal production and operating costs expected to benefit from mill throughput rates that are approximately 25% higher than what was assumed in our 2021 PEA. Geotechnical evaluation has confirmed favourable ground conditions throughout the project footprint including the proposed locations for the process facility, tailings storage facility and rock storage facility. Additional geotechnical drilling of the proposed pit walls is also now complete and has resulted in pit slope assumptions that are mostly in-line or improved versus what was assumed in the PEA. Other scope items for our PFS continue to progress well and we look forward to the delivery of the study in the first quarter of 2023.

"We continue to deliver on key milestones within our ESG program receiving our official ESR Distinction and Great Place to Work certification subsequent to quarter end. We are also targeting the receipt of our Safe Industry and Clean Industry certifications by early 2023. We have recently made investments to support social services for vulnerable groups within the local population of Hidalgo del Parral, the nearest town to Cordero, including the donation of a mobile medical unit and assistance with the construction of a local medical clinic. As we look ahead to 2023 these and similar initiatives will continue to be a core part of our ESG efforts as we focus on having a positive influence on local communities and stakeholders.

"Our balance sheet remains strong with a current cash balance of over $50 million and no debt. This will allow us to complete all our remaining work in 2022 as well as our planned Feasibility Study work in 2023 as we systematically progress Cordero toward development and ultimately its transformation into one of the biggest silver mines globally."

REVIEW OF Q3 2022 & SUBSEQUENT EVENTS:

PFS Metallurgical Test program:

The results from the PFS metallurgical test program on representative samples from its Cordero were released during the quarter. This program represents the most comprehensive test work completed on Cordero to date. Highlights from the locked-cycle flotation test work include:

• Silver recoveries of 94-98%, lead recoveries of 89-97% and zinc recoveries of 92-96% on high grade samples of all major rock types.
• Silver recoveries of 83-92%, lead recoveries of 85-92% and zinc recoveries of 81-89% on medium grade samples of blended rock types.
• Oxide-sulphideblend testwork establish oxide-specific recoveries of ~60% for silver, ~40% for lead and ~85% for zinc via flotation; co-processing oxide mineralized material via flotation eliminates the need for heap leach processing at Cordero.
• Test work overall confirmed higher recoveries than what was assumed in the 2021 PEA.
• All tests were completed at a coarse grind size of p80 passing ~210 micron and demonstrated significantly lower reagent consumption than assumed in the PEA.

• Saleable concentrate grades confirmed and levels of penalty elements for concentrates were insignificant.

Phase 2 drilling:

Final results from our Phase 2 drill program were received in 3Q 2022 and will be incorporated in a resource update and PFS scheduled for completion in the first quarter of 2023. This drill program along with all previous drilling is summarized in the table below. Feasibility study drilling has already commenced and will consist of engineering drilling, resource upgrade drilling and drilling targeting the expansion of the PFS open pit. The total metres to be drilled in the feasibility study drill program will be finalised following the completion of the PFS.

Recent highlight intercepts from Phase 2 drilling include:

• C22-614intercepted 58 m averaging 208 g/t AgEq1 (99 g/t Ag, 0.33 g/t Au, 1.6% Pb and 1.0% Zn) from 78 m and 48 m averaging 231 g/t AgEq1 (100 g/t Ag, 0.63 g/t Au, 1.8% Pb and 0.8% Zn) from 148 m in hole C22-614. These intercepts were from upgrade drilling within the PEA starter pit.
• C22-605intercepted 38.6 m averaging 265 g/t AgEq1 from 27.2 m (89 g/t Ag, 0.13 g/t Au, 1.8% Pb and 3.0% Zn) within an area previously modeled as low grade/waste.
• C22-609,the northeasternmost hole drilled by the Company, intercepted 33.1 m averaging 150 g/t AgEq1 from 233.7 m (54 g/t Ag, 0.08 g/t Au, 0.5% Pb and 1.3% Zn) and 17.7 m averaging 115 g/t AgEq1 (35 g/t Ag, 0.01 g/t Au, 0.9% Pb and 1.4% Zn) from 198.2 m.
• C22-610intercepted 32.6 m averaging 388 g/t AgEq1 (115 g/t Ag, 0.05 g/t Au, 3.7% Pb and 4.1% Zn) from 226.6 m, including 17.8 m averaging 660 g/t AgEq1 (187 g/t Ag, 0.05 g/t Au, 6.5% Pb and 7.2% Zn); the intercept was more than 700 m outside the current resource and approximately 180 m below historic workings at surface.
• C22-634intercepted 42 m averaging 201 g/t AgEq1 (76 g/t Ag, 0.06 g/t Au, 1.0% Pb and 2.4% Zn) from 453 m. This interval is located approximately 20 m below the resource pit.
• C22-644intercepted 125 m averaging 111 g/t AgEq1 (37 g/t Ag, 0.04 g/t Au, 0.4% Pb and 1.6% Zn) from 265 m. This intercept was directly below the 2021 resource pit in an area previously modeled as waste.

Feasibility Study drilling:

Initial Feasibility Study drilling has been focused on two key areas: 1) further upgrading the resource classification within the PEA pit and 2) expanding and upgrading resource blocks between the PEA pit and the Resource constraining pit shells. Highlight intercepts from this drilling includes:

• C22-656intercepted 77 m averaging 126 g/t AgEq1 (46 g/t Ag, 0.08 g/t Au, 0.7% Pb and 1.4% Zn) from 218 m and 22 m averaging 265 g/t AgEq1 (83 g/t Ag, 0.10 g/t Au, 1.8% Pb and 3.2% Zn) from 374 m.
• C2-654intercepted 96 m averaging 124 g/t AgEq1 (33 g/t Ag, 0.03 g/t Au, 0.7% Pb and 1.8% Zn) from 464 m including 36 m averaging 190 g/t AgEq1 (44 g/t Ag, 0.04 g/t Au, 0.9% Pb and 3.1% Zn).

TECHNICAL NOTES & REFERENCES:

Drill results: all drill results in this news release are rounded. Assays are uncut and undiluted. Widths are drilled widths, not true widths, as a full interpretation of the actual orientation of mineralization is not complete. As a guideline, intervals with disseminated mineralization were chosen based on a 25 g/t AgEq cutoff with no more than 10 m of dilution. AgEq calculations are used as the basis for total metal content calculations given Ag is the dominant metal constituent as a percentage of AgEq value in approximately 70% of the Company's mineralized intercepts. AgEq calculations for reported drill results are based on USD $22.00/oz Ag, $1,600/oz Au, $1.00/lb Pb, $1.20/lb Zn. The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices. Refer to notes below for metallurgical recoveries assumed in the 2021 PEA completed on Cordero.

Sample analysis and QA/QC Program: True widths of reported drill intercepts have not been determined. Assays are uncut except where indicated. All core assays are from HQ drill core unless stated otherwise. Drill core is logged and sampled in a secure core storage facility located at the project site 40km north of the city of Parral. Core samples from the program are cut in half, using a diamond cutting saw, and are sent to ALS Geochemistry-Mexico for preparation in Chihuahua City, Mexico, and subsequently pulps are sent to ALS Vancouver, Canada, which is an accredited mineral analysis laboratory, for analysis. All samples are prepared using a method whereby the entire sample is crushed to 70% passing -2mm, a split of 250g is taken and pulverized to better than 85% passing 75 microns. Samples are analyzed for gold using standard Fire Assay-AAS techniques (Au-AA24) from a 50g pulp. Over limits are analyzed by fire assay and gravimetric finish. Samples are also analyzed using thirty three-element inductively coupled plasma method ("ME-ICP61"). Over limit sample values are re-assayed for: (1) values of zinc > 1%; (2) values of lead > 1%; and (3) values of silver > 100 g/t. Samples are re-assayed using the ME-OG62(high-grade material ICP-AES) analytical package. For values of silver greater than 1,500 g/t, samples are re-assayed using the Ag-CON01 analytical method, a standard 30 g fire assay with gravimetric finish. Certified standards and blanks are routinely inserted
