TORONTO, Nov. 12, 2025 (GLOBE NEWSWIRE) -- 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 flow 1 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 price 1 , 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 price 1 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 earnings 1 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 costs 1 averaged $1,339 per ounce sold versus $1,341 per ounce sold in Q2 2025 All-in sustaining costs 1 (“ 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 flow 1 totaled $86.8 million versus free cash flow of ($3.5) million in Q3 2024 and $27.3 million in Q2 2025. Capital expenditures 1 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 expenditures 1 , while $44.4 million were growth capital expenditures 1 . 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 capital 1 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 prod uction 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. Growth capital expenditures at Cordero totaled $4.7 million, which largely related to land acquisition.

PORCUPINE OPERATIONS REVIEW

Discovery’s Porcupine Operations cover approximately 1,400 km 2 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.

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.
