TORONTO, May 14, 2026 (GLOBE NEWSWIRE) -- DiscoverySilverCorp.(TSX: DSV, OTCQX: DSVSF) (“Discovery” or the “Company”) today announced financial and operating results for the first quarter of 2026 (“Q12026”). Discovery began reporting the results of gold production and sales following the Company’s acquisition (“Porcupine Acquisition”) of the Porcupine Complex (“Porcupine”) in and near Timmins, Ontario on April 15, 2025. All dollar amounts are in US dollars, unless otherwise noted.

Tony Makuch, Discovery’s CEO, commented: “Discovery has a vision to more than double gold production, to over 500,000 ounces per year. This growth will come from investing in our Porcupine assets, which include numerous current and past-producing sites in the historic Timmins Camp. During Q1 2026, we made important progress towards achieving our growth objectives.

“First, we announced an agreement to acquire Glencore’s Kidd operations. This acquisition is a major development and provides an opportunity to substantially grow our processing capacity. In addition, the transaction will add extremely valuable land and infrastructure capable of supporting the future expansion of Hoyle Pond and Pamour; deliver important cost synergies; provide exposure to critical minerals; and include attractive exploration upside. The acquisition is expected to close soon.

“Also during Q1 2026, we continued to generate outstanding exploration results, including additional success from resource conversion and extension drilling at all operations, encouraging results at new targets along the western extension of Hoyle Pond, at Borden and at Pamour, and favourable results at both Dome and TVZ.

“We also continued to make progress with our investment programs to grow and optimize our current operations. Capital development and other infrastructure work at Hoyle Pond and Borden, as well as pre-stripping at Pamour, remained on track. Our total sustaining capital expenditures were below planned levels, largely reflecting revised timing for delivery of new mobile equipment to the second and third quarters.

“Turning to our operating performance, as previously reported, production is expected to be weighted to the second half of 2026 with unit costs to improve as production increases. Improved results will be driven by higher processing volumes, largely resulting from increased reliability in the mill, the ramp up of production from the Hollinger open pit and the benefit of investments at our current operations.

“Looking ahead, we remain on track to meet our production, cost and capital expenditure guidance for 2026. In addition, upon closing the Kidd acquisition, we plan to release targets for the remainder of 2026 for copper, zinc and silver production at Kidd Creek Mine, and for anticipated investments in exploration and infrastructure at the Kidd assets.”

Q1 2026

Revenue increased 4% from the previous quarter to $285.0 million, reflecting an increase of 18% in the average realized gold price, to $4,908 per ounce.

EBITDA(1)(2)totaled $177.9 million compared to net loss before interest, taxes, and depreciation and amortization of $6.3 million in Q1 2025 and EBITDA of $126.0 million in Q4 2025 (Q4 2025 reduced by a one-time $45.0 million reclamation expense for non-operating sites). Netearningstotaled $81.7 million, or $0.10 per basic share, compared to net loss of $6.5 million, or $0.02 per basic share, in Q1 2025, and net earnings of $65.3 million, or $0.08 per basic share, the previous quarter. Adjusted net earnings(1)totaled $82.7 million, or $0.10 per basic share, which compared to adjusted net loss of $3.0 million, or $0.01 per basic share, in Q1 2025, and adjusted net earnings of $113.5 million, or $0.14 per basic share, the previous quarter (Q4 2025 adjusted net earnings included a $0.05 per basic share benefit in earnings from a deferred tax recovery related to revised reclamation cash flow projections).

Keyoperatingresults: Gold production of 60,269 ounces compared to 66,718 ounces in Q4 2025, mainly reflecting a planned reduction in tonnes processed, partially offset by a 15% improvement in average grade and higher average recoveries. Gold sold(3)of 56,927 ounces compared to 64,479 ounces the previous quarter. Total production costs of $76.2 million versus $73.8 million in Q4 2025. Operating cash costs(1)of $1,417 per ounce sold compared to $1,185 per ounce sold the previous quarter. Site-level AISC(1)(4)(5)of $1,875 per ounce sold versus $1,824 per ounce sold in Q4 2025. AISC(1)(5)of $2,041 per ounce sold compared to AISC of $2,034 per ounce sold the previous quarter.

Cashflowsincluded net cash flow from operating activities of $43.0 million ($129.8 million before the impact of a $86.8 million income tax payment relating to the 2025 tax year); Adjusted free cash flow(1)of $62.7 million compared to adjusted free cash outflow of ($9.8) million in Q1 2025 and adjusted free cash inflow of $67.9 million in Q4 2025. Capital expenditures(1)totaled $69.9 million, including $20.7 million of sustaining capital expenditures(1)and $49.2 million of growth capital expenditures(1)(includes growth capital expenditures for Porcupine and Cordero, as well as capitalized exploration expenditures). Sustaining capital expenditures in Q1 2026 were largely focused on capital development at Hoyle Pond and Borden, combined with construction work to 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. Cashat March 31, 2026, totaled $384.9 million compared to $410.7 million at December 31, 2025, with the change in cash mainly resulting from a $86.8 million income tax payment related to the 2025 tax year made during Q1 2026, the impact of which more than offset the benefit of cash flows from operations generated during the quarter. Working capital(1)at March 31, 2026, totaled $288.2 million as compared to working capital of $242.2 million at December 31, 2025. The 19% increase in working capital mainly reflected the reduction in current tax payable following the $86.8 million 2025 income tax payment.

PORCUPINE OPERATIONS REVIEW

Discovery’s Porcupine Operations consist 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 Porcupine Operations also includes the Borden mine property and large land position near Chapleau, Ontario. Current operations include the Hoyle Pond and Borden underground mines, and Pamour and Hollinger open-pit mines. All mineralization is processed at Dome, including mineralization from Borden, which is trucked 190 km to the Dome 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 in 2025, the Company is targeting a return to sustained nameplate capacity by 2027 or sooner.

(1) Includes gold production, poured and sold from Hoyle Pond, Borden, Pamour and Hollinger. (2) The difference between ounces produced and ounces sold largely reflects the delivery of in-kind ounces under the Franco-Nevada royalty arrangement. (3) Example of Non-GAAP measure. See the section in this press release entitled, “NON-GAAP MEASURES” for more information.

During Q1 2026, a total of 698,984 tonnes were processed at Porcupine Complex at an average grade of 2.96 g/t, with recovery rates averaging 90.6%, which compared to 892,818 tonnes at an average grade of 2.58 g/t and recovery rates averaging 90.2% in the previous quarter. A total of 60,269 ounces of gold were produced over this period, with total gold poured of 59,258 ounces, versus 66,718 ounces and 67,010 ounces produced and poured, respectively, in the previous quarter. The change in production in Q1 2026 reflected lower tonnes processed, the impact of which was partially offset by a 15% improvement in the average grade, reflecting a significantly higher grade at Hoyle Pond, and a higher average recovery rate. More than three quarters of the reduction in tonnes processed was planned and related to scheduled maintenance as well as the expected impact of severe winter conditions on the crushing circuit. The Company is currently advancing plans to replace the crushing circuit. Total ore tonnes mined increased by 4% compared to Q4 2025, with there being close to 1.3 million tonnes of stockpiled material available for processing as at March 31, 2026.

Also contributing to the reduction in tonnes processed was unscheduled downtime largely due to reduced availability rates in the crushing circuit caused largely by damage to screens in the secondary and tertiary crushers. While the Company works towards replacing the crushing system, initiatives have been taken to increase availability rates, including adding critical spares at site, and ordering a newly designed screening system, which is scheduled for delivery at the end of the second quarter.

Based on full operating days, the Dome Mill's processing capabilities continued to achieve significant improvement with daily throughput exceeding 11,000 tonnes per day on 26 days in Q1 2026, including 10 days when the mill achieved the operating capacity of over 12,000 tonnes per day. Mill operating costs during Q1 2026 averaged $24.94 per tonne processed compared to $21.68 per tonne processed in the previous quarter, with the change largely reflecting reduced processing volumes.

Production costs, including mining and processing costs, in Q1 2026 totaled $76.2 million versus $73.8 million in the previous quarter. Operating cash costs(1)per ounce sold averaged $1,417 compared to $1,185 in the previous quarter, with the increase mainly reflecting higher mining costs, given increased mining rates in Q1 2026, and the impact of lower gold sold. Site-level AISC(1)(2)averaged $1,875 per ounce sold compared to $1,824 in Q4 2025. The quarter-over-quarter increase in AISC reflected higher operating cash costs, partially offset by a reduction in sustaining capital expenditures(1) to $19.0 million in Q1 2026 versus $32.9 million the previous quarter. Sustaining capital expenditures in Q1 2026 mainly related to capital development at both Hoyle Pond and Borden and construction work to buttress the TMA6 at the Dome property.

(1) Example of Non-GAAP measure. For more information, see the section in this press release entitled, “NON-GAAP MEASURES.” (2) Site-level AISC includes corporate G&A allocation and excludes remaining corporate 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 dated February 16, 2024 (the “February 2024 Feasibility Study”) 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 is capable of generating substantial free cash flows and attractive economic returns.

Key highlights of the FS include:

Average annual production of 37.0 million silver equivalent ounces(1)(“AgEq”) over the first 12 years with a total project life of 19 years; AISC(2)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 expenditures(2)of $606.0 million (resulting in a NPV to capital ratio of 2:1); Large-scale Mineral Reserves totaling 302 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.
