TORONTO, Nov. 12, 2025 -- Discovery Silver Corp. (TSX: DSV, OTCQX: DSVSF) ("Discovery" or the "Company") today announced the Company's financial and operating results for the third quarter ("Q3 2025") and first nine months ("YTD 2025") of 2025. Discovery began reporting the results of gold production and sales following the Company's acquisition ("Acquisition" or "Porcupine Acquisition") of the Porcupine Complex ("Porcupine") in and near Timmins, Ontario on April 15, 2025. The Company's full financial statements and management discussion & analysis are available on SEDAR+ at www.sedarplus.ca and on the Company's website at www.discoverysilver.com. All dollar amounts are in US dollars, unless otherwise noted.

Tony Makuch, Discovery's CEO, commented: "During Q3 2025, we generated solid operating and financial results while at the same time continuing to integrate systems, align policies and procedures, strengthen management structures and advance investment programs at Porcupine. A key highlight of the third quarter was cash flow, with net cash from operating activities of $153.5 million and free cash flow¹ totaling $86.8 million. Strong cash flow resulted from a 56% increase in gold sales, to 66,200 ounces from 42,550 ounces the previous quarter, and an increase in the average realized gold price¹, to $3,489 per ounce sold. Driven by strong cash flow generation, we grew our cash position by 35%, to $341.5 million at September 30, 2025. With our current cash, as well as a new revolving credit facility for $250 million, plus a $100 million accordion feature, Discovery is very well capitalized as it moves forward with investment plans aimed at growing production, improving costs and maximizing value creation at Porcupine.

"A key component of the tremendous potential at Porcupine involves exploration. Last week, we issued our first exploration update, which included excellent drill results from resource conversion and expansion drilling at Hoyle Pond, Borden and Pamour, as well as very encouraging results at Owl Creek, which confirm the presence of high-grade mineralization three kilometers to the west of Hoyle Pond. We also announced the commencement of drilling programs at Dome Mine and the TVZ Zone. Dome and TVZ have the potential to become two new mining operations that could substantially grow production and value creation in Timmins. Drilling at Dome and TVZ is being conducted as part of studies to more thoroughly evaluate the projects, with these studies targeted for completion in 2026."

Q3 2025

• Revenue in Q3 2025 totaled $237.0 million that resulted from gold sales of 66,200 ounces at an average realized gold price¹ of $3,489 per ounce.
• EBITDA^1,2 of $122.1 million compared to a loss before interest, taxes and depreciation and amortization of $3.9 million in Q3 2024 and EBITDA of $55.2 million in Q2 2025. The significant improvement in EBITDA compared to the previous quarter largely reflected the favourable impact on earnings of a 67% increase in revenue from Q2 2025 and a reduction in corporate G&A costs.
• Net earnings totaled $42.4 million, or $0.05 per basic share, versus a loss of $3.9 million, or $0.01 per basic share, in Q3 2024 and net earnings of $5.5 million, or $0.01 per basic share, in Q2 2025.
• Adjusted net earnings¹ totaled $61.1 million, or $0.08 per basic share, compared to adjusted net loss of $2.3 million, or $0.01 per basic share, in Q3 2024 and adjusted net earnings of $28.4 million, or $0.04 per basic share, the previous quarter. The main differences between net earnings and adjusted net earnings in Q3 2025 related to the exclusion from adjusted net earnings of the after-tax impacts of $18.5 million of purchase price allocation ("PPA") adjustments, $3.3 million related to transition services agreement ("TSA") costs and $1.6 million of transaction-specific business development costs, partially offset by the exclusion of $9.2 million of foreign exchange gains.
• Solid operating performance in Q3 2025:
  • Production of 63,154 ounces compared to 50,552 ounces the previous quarter (76 days from April 16, 2025 to June 30, 2025)
  • Gold sales of 66,200 ounces versus 42,550 ounces in Q2 2025
  • Production costs of $106.8 million compared to $54.9 million the previous quarter (Q3 2025 production costs included the $18.5 million of PPA adjustments ($nil in Q2 2025) and $3.3 million of TSA costs ($2.4 million in Q2 2025).
  • Operating cash costs¹ averaged $1,339 per ounce sold versus $1,341 per ounce sold in Q2 2025
  • All-in sustaining costs¹ ("AISC") averaged $1,734 per ounce sold compared to $2,074 per ounce sold the previous quarter; Site-level AISC in Q3 2025 averaged $1,699 per ounce sold versus $1,849 per ounce sold in Q2 2025. See the Operating cash costs and AISC tables in the Non-GAAP Measures section near the end of this press release for more information.
• Cash flows included net cash from operating activities of $153.5 million, which compared to net cash used in operating activities of $1.2 million in Q3 2024 and net cash from operating activities of $67.1 million the previous quarter.
• Free cash flow¹ totaled $86.8 million versus free cash flow of ($3.5) million in Q3 2024 and $27.3 million in Q2 2025.
• Capital expenditures¹ in Q3 2025 totaled $65.2 million, with an additional $1.4 million of finance leases. Of the $65.2 million, $20.8 million related to sustaining capital expenditures¹, while $44.4 million were growth capital expenditures¹. Sustaining capital expenditures were largely focused on capital development at Hoyle Pond and Borden and construction work to raise and buttress the No. 6 tailings management area ("TMA6") at the Dome property. Growth capital expenditures primarily related to pre-stripping at Pamour and longer-term investments at the TMA6.
• Cash at September 30, 2025, totaled $341.5 million compared to $252.5 million at June 30, 2025, with the increase in cash mainly resulting from the $86.8 million of free cash flow generated during Q3 2025.
• Working capital¹ at September 30, 2025 totaled $224.2 million as compared to working capital of $17.0 million at December 31, 2024 and $225.9 million at June 30, 2025. The 35% increase in cash during Q3 2025 was offset by lower inventory levels as well as higher current tax payable, employee-related benefits and other current liabilities in accounting for the change in working capital compared to June 30, 2025.

YTD 2025

Discovery did not generate revenue or earnings from mine operations in YTD 2024 or Q1 2025.

• Gold production totaled 113,706 ounces, while gold sales totaled 108,750 ounces. Revenue of $379.0 million resulted from gold sales and an average realized price of $3,430 per ounce. Production costs totaled $161.7 million. Operating cash costs averaged $1,340 per ounce sold, while AISC per ounce sold averaged $1,863.
• EBITDA was $171.0 million versus a loss before interest, taxes and depreciation and amortization of $9.5 million in YTD 2024, with earnings generated following the Porcupine Acquisition in Q2 2025 mainly accounting for the significant improvement in EBITDA performance.
• Net earnings totaled $41.5 million, or $0.06 per basic share, versus net loss of $9.5 million, or $0.02 per basic share, in YTD 2024, with the prior year net loss largely resulting from corporate G&A costs, share-based compensation expense and foreign exchange losses during YTD 2024.
• Average basic shares outstanding were 648.0 million shares versus 399.5 million shares for the same period a year earlier, with the increase mainly due to the impact of the 401.8 million shares issued during Q2 2025 in relation to the Porcupine Acquisition and the Company's Financing Package.
• Adjusted net earnings were $86.5 million, or $0.13 per basic share, respectively, compared to adjusted net loss of $6.4 million, or $0.02 per share, in YTD 2024. The difference between net earnings and adjusted net earnings in YTD 2025 mainly reflected the exclusion from adjusted net earnings of the after-tax impacts of $21.8 million of transaction-specific business development expenses primarily related to the Porcupine Acquisition, the $18.5 million of PPA adjustments and $5.7 million of TSA costs.
• Net cash from operating activities in YTD 2025 totaled $214.5 million, while free cash flow totaled $104.3 million.
• Total capital expenditures totaled $112.5 million, with an additional $2.2 million of finance leases. Of the $112.5 million of capital expenditures, $37.0 million related to sustaining capital expenditures and $75.5 million were growth capital expenditures. Porcupine accounted for $70.8 million of growth capital expenditures in YTD 2025, mainly reflecting pre-stripping at Pamour and TMA6 expenditures.

Income Statement Summary

PORCUPINE OPERATIONS REVIEW

Discovery's Porcupine Operations cover approximately 1,400 km² in and near Timmins, Ontario. Porcupine consists of the Hoyle Pond, Pamour and Hollinger mine properties, the Dome mine property and milling facility, and numerous near-mine and regional exploration targets. The Complex also includes the Borden mine property and large land position near Chapleau, Ontario. Current operations include the Hoyle Pond and Borden underground mines, with the Pamour open-pit project currently ramping up towards commercial levels of production. All mineralization is processed at the Dome, including mineralization from Borden, which is trucked 190 km to the mill. The Dome Mill is a 12,000 tonne-per-day processing facility that in recent years has operated at rates well below optimal levels. Through investment programs launched following the closing of the Porcupine Acquisition, the Company is targeting a return to full capacity operations by 2028 or sooner.

(1) Includes gold production, poured and sold from Hoyle Pond, Borden and Pamour.
(2) Example of Non-GAAP measure. See the section in this press release entitled, "NON-GAAP MEASURES" for more information.
(3) Operating cash costs per ounce sold, AISC per ounce sold and total capital expenditures are site level and exclude remaining corporate G&A, share-based compensation costs and corporate-level sustaining capital expenditures.

During Q3 2025, a total of 808,688 tonnes were processed at Porcupine Complex at an average grade of 2.69 g/t, with recovery rates averaging 90.3%, which compared to 508,791 tonnes at an average grade of 3.39 g/t and recovery rates averaging 91.3% for the 76 days from April 16, 2025 to June 30, 2025 in Q2 2025. A total of 63,154 ounces of gold were produced over this period, with total gold poured of 65,978 ounces, compared to 50,552 and 46,608 ounces produced and poured respectively, in the previous quarter. Higher production in Q3 2025 mainly reflected the favourable impact of increased mining rates and higher average grades at both Borden and Pamour, partially offset by a reduction in mining rates and average grades at Hoyle Pond. During Q3 2025, production at Hoyle Pond was impacted by ventilation constraints during a period of high temperatures, which limited access to higher-grade area of the S Zone Deep.

Availability rates at the Dome Mill during Q3 2025 were impacted by a scheduled five-day maintenance shutdown in July for the purpose of replacing the discharge head and shell of B Rod Mill, rebuild of the tertiary crusher, and feeder repairs at the coarse ore stockpile. The Company used the occasion of the shutdown to advance multiple other projects, primarily in the grinding water system, repair to the mill reclaim water pond and carbon handling circuits. Based on operating days during Q3 2025, mill throughput averaged approximately 9,295 tonnes per day. Mill operating costs during Q3 2025 totaled $17.1 million for an average of $21.15 per tonne processed, which compared to $12.9 million and an average of $25.4 per tonne, respectively, the previous quarter, with the improvement in operating costs per tonne resulting from the 59% increase in tonnes processed. Mill costs are allocated to the mine operations based on a proportion of total tonnes processed.

For YTD 2025 a total of 1,317,480 tonnes were processed at Dome Mill at an average grade of 2.96 g/t, with recovery rates averaging 90.7%. A total of 113,706 ounces of gold were produced over this period, with total gold poured of 112,586 ounces. Total mill operating costs were $30.0 million for YTD 2025, for an average of $22.75 per tonne processed. The mill costs are allocated to the mine operations based on a proportion of total tonnes processed.

Production costs, including mining and processing costs, in Q3 2025 totaled $106.8 million versus $54.9 million in the previous quarter. Operating cash costs¹ averaged $1,339 compared to $1,341 in the previous quarter. Site-level AISC^1,2 averaged $1,699 per ounce sold compared to $1,849 in Q2 2025. Included in Q3 2025 AISC was $22.1 million of sustaining capital expenditures¹, mainly related to capital development activities and capital expenditures related to the TMA6, which increased from $14.8 million in Q2 2025. The improvement in AISC was due to a 63% increase in ounces of gold sold, lower accretion and amortization of site closure provisions, partially offset by higher sustaining capital expenditures.
For YTD 2025, production costs totaled $161.7 million, with operating cash costs averaging $1,340 per ounce sold and AISC averaging $1,756 per ounce sold. Included in AISC were $36.8 million of sustaining capital expenditures related to capital development and expenditures related to the TMA6.

(1) Example of Non-GAAP measure. See the section in this press release entitled, "NON-GAAP MEASURES" for more information.
(2) Site-level AISC includes corporate G&A allocation and excludes remaining G&A, share-based compensation costs and corporate-level sustaining capital expenditures.

CORDERO OVERVIEW

The Cordero Project was acquired by Discovery in 2019. Since that time, the Company has invested over $100.0 million in Mexico, conducting significant exploration drilling and technical analysis, leading to the release of multiple studies, most recently the feasibility study ("FS") dated February 16, 2024 and filed on SEDAR+ (www.sedarplus.ca) on March 28, 2024. The results of the FS confirmed Cordero to be one of the world's largest undeveloped silver deposits, with the potential for large-scale production at low unit costs and that is capable of generating substantial free cash flow and attractive economic returns.

Key highlights of the FS include:

• Average annual production of 37.0 million silver equivalent ounces¹("AgEq") over the first 12 years with a total project life of 19 years;
• AISC² averaging below $12.50 per AgEq ounce in Years 1 - 8;
• Base-case after-tax net present value ("NPV") of $1.2 billion (Base-case metal prices: Silver - $22.00 per ounce; Gold - $1,600 per ounce; Zinc - $1.20 per ounce; Lead - $1.00 per ounce);
• Initial capital expenditures² of $606.0 million (resulting in a NPV to capital ratio of 2:1);
• Large-scale Mineral Reserve totaling 302.0 million ounces of silver, 840,000 ounces of gold, 5.2 billion pounds of zinc and 3.0 billion pounds of lead;
• Important socio-economic contribution to Mexico, including an initial investment of over $600 million, the creation of 2,500 jobs during development, and over 1,000 jobs during operations, $4.0 billion in total procurement, all to remain within Mexico, and, assuming a fixed $35.00 per ounce silver price, total tax contributions within Mexico of $2.4 billion over the project life; and,
• High levels of environmental responsibility and a commitment to contributing to the management of key social issues such as carbon reduction and water quality and availability.

Third Quarter 2025 Highlights

During Q3 2025, Discovery continued work on key initiatives to further de-risk the project, including:

• Assessing the potential to use natural gas power sources versus the grid power supply expected to complete in Q4;
• Advancing geotechnical (completed in early Q4) and other work related to the planned upgrade of the local water treatment plant;
• Evaluating the potential to establish solar farms around the project site to contribute to the power supply required for mine development and operation; and,
• Participation in ongoing discussions with the various governmental bodies involved in issuing the permits for the project.

(1) AgEq produced is metal recovered in concentrate. AgEq is calculated as Ag + (Au x 72.7) + (Pb x 45.5) + (Zn x 54.6); these factors are based on metal prices of Ag - $22/oz, Au - $1,600/oz, PB - $1,00/lb and Zn - $1.20/lb (2) use in the February 2024 FS.

OUTLOOK

With the closing of the Porcupine Acquisition on April 15, 2025, Discovery was transformed into a diversified North American-focused precious metals producer combining growing gold production in Northern Ontario, Canada, with one of the world's largest silver development projects in Chihuahua State, Mexico.

Key priorities for the Porcupine Operations in 2025 continue to include:

• Implementing investment plans aimed at growing mining rates, increasing production levels and lowering unit costs at Hoyle Pond and Borden;
• Ensuring the successful ramp up of production at Pamour;
• Advancing studies on the TVZ zone, Dome Mine project and Dome Mill expansion; and,
• Advancing numerous exploration opportunities at each of site, as well as at regional targets.

The Company is currently executing a 140,000-metre drill program, which is expected to be completed early in 2026. The goals for the drilling program include resource conversion and expansion at Hoyle Pond, Borden and Pamour, in support of an updated technical report, to be issued in 2026, as well as the evaluation of district level targets, including Owl Creek, located approximately three kilometers west of Hoyle Pond. In addition, drilling is also being conducted at both Dome Mine and the TVZ Zone as part of studies to further advance and evaluate these high-potential targets.

With $341.5 million of cash at September 30, 2025, and the $250 million RCF, the Company is well capitalized to fund growth and optimization plans for Porcupine and current expenditure plans at Cordero.

In Mexico, the Company plans to further advance and de-risk the Cordero project, with key areas of focus being power, water availability and management, permitting, and the continuation of ESG and community outreach programs.

Following the completion of the land acquisition program in March 2025, the next major milestone for Cordero will be approval of the Company's Environmental Impact Assessment or MIA by SEMARNAT, which was submitted in August 2023. The MIA passed SEMARNAT's legal review soon after its submission and was advanced for technical review. As of the date of this press release, the Company had completed the technical review process and was awaiting approval of the MIA. The Company remains confident that Cordero will receive MIA approval.

ABOUT DISCOVERY

Discovery is a growing North American-focused precious metals company. The Company has exposure to silver through its first asset, the 100%-owned Cordero project, one of the world's largest undeveloped silver deposits, which is located close to infrastructure in a prolific mining belt in Chihuahua State, Mexico. On April 15, 2025, Discovery completed the acquisition of the Porcupine Complex from Newmont Corp., transforming the Company into a new Canadian gold producer with multiple operations in one of the world's most renowned gold camps in and near Timmins, Ontario. Discovery owns a dominant land position within the camp, with a large base of Mineral Resources remaining and substantial growth and exploration upside.

NON-GAAP MEASURES

The Company has included certain non-GAAP measures in this document, as detailed below. In the mining industry, these are common performance measures and ratios but may not be comparable to similar measures or ratios presented by other issuers and the non-GAAP measures and ratios do not have any standardized meaning. Accordingly, these measures and ratios are included to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS Accounting Standards. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers.

Free Cash Flow

Free Cash Flow is a non-GAAP performance measure that is calculated as cash flows from operations net of cash flows invested in mineral property, plant, and equipment and exploration and evaluation assets. The Company believes that this measure is useful to the external users in assessing the Company's ability to generate cash flow after capital investments and build the cash resources of the Company.

Free cash flow is reconciled to the amounts include in the Consolidated Statements of Cash Flows as follows:

Sustaining and Growth Capital

Sustaining capital and growth capital are non-GAAP measures. Sustaining capital is defined as capital required to maintain current operations at existing levels. Growth capital is defined as capital expenditures for major growth projects or enhancement capital for significant infrastructure improvements at existing operations. Both measurements are used by management to assess the effectiveness of investment programs.

Operating Cash Costs and Operating Cash Costs per Ounce Sold

Operating cash costs and operating cash costs per ounce sold are non-GAAP measures. In the gold mining industry, these metrics are common performance measures but do not have any standardized meaning under GAAP. Operating cash costs include mine site operating costs such as mining, processing, administration and royalty expenses but exclude depreciation and depletion and reclamation costs. Operating cash cost per ounce sold is based on ounces sold and is calculated by dividing operating cash costs by volume of gold ounces sold.

The Company discloses operating cash costs and operating cash cost per ounce sold as it believes the measures provide valuable assistance to investors and analysts in evaluating the Company's operational performance and ability to generate cash flow. The most directly comparable measure prepared in accordance with GAAP is production costs. Operating cash costs and operating cash costs per ounce sold should not be considered in isolation or as a substitute for measures prepared in accordance with GAAP.

AISC and AISC per Ounce Sold

AISC and AISC per ounce sold are non-GAAP measures. These measures are intended to assist readers in evaluating the total costs of producing and selling gold from current operations. While there is no standardized meaning across the industry for this measure, the Company's definition conforms to the definition of AISC as set out by the World Gold Council in its guidance note dated June 27, 2013.

The Company defines AISC as the sum of operating costs (as defined and calculated above), sustaining capital, exploration expense, corporate expenses, lease payments relating to sustaining assets, and reclamation cost accretion and depreciation related to current operations. Corporate expenses include general and administrative expenses, net of transaction related costs, severance expenses for management changes and interest income. AISC excludes growth capital expenditures, growth exploration expenditures, reclamation cost accretion and depreciation not related to current operations, lease payments related to non-sustaining assets, interest expense, debt repayment and taxes.

Operating cash costs and AISC Reconciliation

The following tables reconciles these non-GAAP measures to the most directly comparable GAAP measures for the three and nine months ended September 30, 2025, and the three months ended June 30, 2025.

(1) Costs not reflective of normal operations.
(2) Purchase price allocation represents the depletion of inventories acquired with the business combinations.
(3) Excludes certain items not reflective of normal operations.
(4) Includes the write-down of software.

(3) For Q2 2025, the ounces sold (1,984 ounces) and the cash payments ($6.6 million) in the operating cash costs per ounce sold and AISC per ounce sold calculations that related to the Franco Royalty arrangement have been excluded. The change to reported operating cash costs per ounce sold and AISC per ounce sold is $93 per ounce and $59 per ounce, respectively.

Average Realized Price per Ounce Sold

In the gold mining industry, average realized price per ounce sold is a common performance measure that does not have any standardized meaning. The most directly comparable measure prepared in accordance with GAAP is revenue from gold sales. Average realized price per ounces sold should not be considered in isolation or as a substitute for measures prepared in accordance with GAAP. The measure is intended to assist readers in evaluating the total revenues realized in a period from current operations.

Adjusted Net Earnings and Adjusted Net Earnings per Share

Adjusted net earnings and adjusted net earnings per share are used by management and investors to measure the underlying operating performance of the Company. Adjusted net earnings is defined as net earnings adjusted to exclude the after-tax impact of specific items that are significant, but not reflective of the underlying operations of the Company, including foreign exchange gains and losses and other non-recurring items. Adjusted net earnings per share is calculated using the weighted average number of shares outstanding for adjusted net earnings per share.

Earnings before Interest, Taxes, Depreciation, and Amortization ("EBITDA")

EBITDA represents net earnings before interest, taxes, depreciation and amortization. EBITDA is an indicator of the Company's ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations, and fund capital expenditures.

The following is a reconciliation of EBITDA to the consolidated financial statements:

Working Capital

Working capital is a non-GAAP measure. In the gold mining industry, working capital is a common measure of liquidity, but does not have any standardized meaning. The most directly comparable measure prepared in accordance with GAAP is current assets and current liabilities. Working capital is calculated by deducting current liabilities from current assets. Working capital should not be considered in isolation or as a substitute for measures prepared in accordance with GAAP. The measure is intended to assist readers in evaluating the Company's liquidity. Working capital is reconciled to the amounts in the Consolidated Statements of Financial Position as follows:
