DISCOVERY REPORTS 50,552 OUNCES OF

GOLD PRODUCTION, $27.3 MILLION OF

FREE CASH FLOW1 IN Q2 2025

August 12 , 2025 , Toronto, Ontario - Discovery Silver Corp. (TSX: DSV,

OTCQX: DSVSF) (“ Discovery” or the “ Company”) today announced the

Company’s financial and operating results for the second quarter ( “Q2

2025”) and first six months (“YTD 2025”) of 2025. Q2 2025 represents the

first quarter Discovery has reported the results of gold production and

sales following the Company’s acquisition (“Acquisition” or “ Porcupine

Acquisition”) of the Porcupine Complex (“Porcupine” or the “Porcupine

Operations”) 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: “ Q2 2025 was Discovery’s

first quarter as a Canadian gold produce r. During the quarter, we

integrated systems, strengthened management structures and began

implementing investment programs at Porcupine aimed at improving

existing operations and pursuing growth opportunities. It was a

significant challenge, and I want to thank our team for delivering a

quarter of excellent progress. W e also turned in a solid quarter of

operating and financial performance, producing 50,552 ounces in the 76

days that we owned the assets. Gold sales of 42,550 ounces were below

gold produced with the gold inventory at quarter end to be sold during

Q3 2025. Net cash from operations totaled 67.1 million, while free cash

flow was $27.3 m illion. Adjusted net earnings 1 totaled $28.4 million or

$0.04 per share.

“Key investment programs initiated during Q2 205 included investments

at Dome Mill, mainly in the crushing, grinding and carbon handling

circuits, advancing work at the Dome tailings management area (“TMA”),

continuing to ramp up Pamour, with pre-stripping and production levels

meeting target levels, and commencing investment s at Hoyle Pond and

Borden to optimize and grow the operations . We also began deploying

drills as part of an extensive exploration program targeting numerous

near-mine and district targets at Hoyle Pond, Borden and Pamour, and

supporting the evaluation of high-potential new sources of production,

including the TVZ zone and the resumption of mining at Dome Mine.

“Looking ahead, we are targeting production levels to increase in the final

two quarters of the year. We also plan to ramp up our capital investment

and exploration programs as we move forward with our growth and value

creation plans for Porcupine.”

Q2 2025

• Revenue in Q2 2025 totaled $142.0 million that resulted from gold sales of 42,550 ounces at an average

realized gold price1 of $3,337 per ounce.

• EBITDA1,2 of $55.2 million compared to a loss before interest, taxes and depreciation and amortization

of $5.1 million and $6.3 million in Q2 2024 and Q1 2025, respectively. The significant improvement in

EBITDA performance resulted from revenue and earnings generated from gold sales following

completion of the Porcupine Acquisition on April 15, 2025.

• Net earnings totaled $5.5 million ($0.01 per basic share) versus a loss of $5.1 million ($0.01 per basic

share) in Q2 2024 and net loss of $6.5 million ($0.02 per basic share) in Q1 2025.

• Adjusted net earnings1 totaled $28.4 million ($0.04 per basic share) versus adjusted net loss of $3.0

million ($0.01 per basic share) in Q2 2024 and adjusted net loss of $3.0 million ($0.01 per basic share)

the previous quarter; The difference between net earnings and adjusted net earnings reflected the

after-tax impact of $16.6 million of acquisition-related costs, mainly for legal, consulting and advisory

services, and other expenses, $ 6.8 million of foreign exchange losses and $2.4 million of transition -

related costs involving the Porcupine Operations.

• Solid operating performance in initial quarter of production at Porcupine (April 1 6, 2025, to June 30,

2025):

3

o Production of 50,552 ounces, comprised of 16,112 ounces at Hoyle Pond, 27,286 ounces

at Borden and 7,154 ounces at Pamour

o Gold poured totaling 46,608 ounces, with gold sales of 42,550 ounces

o Production costs of $54.9 million

o Operating cash costs1 averaging $1,334 per ounce sold

o All-in sustaining costs1 (“AISC”) averaging 2,123 per ounce sold; Site-level AISC averaging

$1,872 per ounce sold (see the Operating Cash Costs and AISC tables in Non -GAAP

Measures section near the end of this press release for more information).

• Cash flows included net cash provided by operating activities of $67.1 million, which compared to net

used by operations activities of $8.5 million and $6.1 million in Q2 2024 and Q1 2025, respectively.

• Free cash flow 1 totaled $27.3 million versus free cash flow of ($10.7) million in Q2 2024 and ($9.8)

million in Q1 2025.

• Capital expenditures1 totaled $44.2 million, with sustaining capital expenditures1 accounting for $16.1

million and growth capital expenditures1 totaling $28.1 million; Sustaining capital expenditures largely

focused on capital development at Hoyle Pond and Borden and construction work to raise and buttress

the No. 6 tailings impoundment area (“TMA”), while the $28.1 million of growth capital expenditures

related to pre-stripping at Pamour, with the remainder largely related to longer -term investments at

the TMA.

1. Capital expenditures incurred at Dome Mill and the TMA are allocated to Porcupine’s mining operations based on their proporti on of mill fee

provided to Dome Mill.

• Cash at June 30, 2025 totaled $252.5 million reflecting approximately $475.0 million of gross proceeds

($468.7 million of net proceeds after share issue costs) from a financing package (the “ Financing

Package”) arranged in conjunction with the Porcupine Acquisition, as well as $67.1 million of net cash

from operating activities generated during Q2 2025 , partially offset by $200 .6 million of cash

consideration paid for the Porcupine Operations at closing, the $44.2 million of capital expenditures

during Q2 2025, as well as the impact of $51.6 million of restricted cash related to letters of credit and

cash collateral for government required financial assurances in relation to closure plans involving the

Porcupine assets.

1. The difference between the $39.8 million of Acquisitions of mineral interests, property and equipment

and total capital expenditures of $44.2 million relates to the timing of cash expenditures relative to the

accrual of capital expenditures for accounting purposes.

• Working capital 1 at June 30, 2025, totaled $225.9 million as compared to working capital of $17.0

million at December 31, 202 4. The working capital balance at June 30, 2025, reflected the significant

increase in cash during Q2 2025 as well as higher levels of short-term trade and other receivables and

inventories, offset by higher current liabilities, mainly accounts payable and ac crued liabilities,

reclamation liabilities, deferred revenue, current income tax and employee-related benefits.

YTD 2025

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

• Net loss for YTD 2025 totaled $ 0.9 million, or $0.0 0 per basic share , compared to net loss of $5.6

million, or $0.01 per basic share, in YTD 2024.

• Adjusted net earnings1 and adjusted net earnings per basic share1 were $ 25.4 million and $0.0 4,

respectively, which compared to adjusted net loss and adjusted net loss per basic share of $4.5 million

and $0.01, respectively, 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 impact of $20.2

million of business development expenses related to the Porcupine Acquisition, $6.7 million of foreign

exchange losses, as well as $2.4 of one-time transition-related costs.

• EBITDA1,2 for YTD 2025 totaled $48.9 million versus a loss before interest, taxes and depreciation and

amortization of $5.6 million in YTD 2024 . The difference between net earnings and EBITDA mainly

reflected the exclusion from EBITDA of $ 16.4 million of depletion and depreciation expense , $14.4

million of net finance costs, largely due to accretion expense from reclamation and deferred

consideration and interest expense related to royalty agreements entered into with Franco -Nevada

Corp. concurrent with the completion of the Porcupine Acquisition, and $19.0 million of income tax

expense.

• Net cash provided by operating activities in YTD 2025 totaled $6 1.0 million, while free cash flow 1

totaled $17.5 million.

• Total capital expenditures 1 for YTD 2025 totaled $48.1 million, including $ 16.2 million of sustaining

capital expenditures1, $31.1 million of growth capital expenditures1 and $0.8 million related to financial

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 from the operating mines, and Pamour, is processed

at Dome, including mineralization from Borden, which is trucked 190 km to the Dome Mill.

DOME MILL

The current Dome Mill was commissioned in 1988, with expansion projects being completed in 1995 and

2004. The mill consists of three -stage crushing, two parallel rod mill and ball mill circuits, a single leach

6

and Carbon-in-Pulp circuit, followed by a carbon strip and electrowinning circuit. The Mill’s nameplate

operating capacity is approximately 12,000 tonnes per day (approximately 4.3 million tonnes per annum).

In recent years, the mill has operated at rates well below capacity levels, largely reflecting increased

maintenance requirements which contributed to reduced availability and utilization rates, as well as

production shortfalls from mining operations. 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.

For the period April 16, 2025, to June 30, 2025, a total of 508,791 tonnes were processed at Dome Mill at

an average grade of 3.39 g/t, with recovery rates averaging 91.3%. A total of 50,552 ounces of gold were

produced over this period, with total gold poured of 46,608 ounces. Availability rates at the Dome Mill

during Q2 2025 were impacted by a two-week maintenance shutdown, previously scheduled by the prior

owner, for the purpose of replacing equipment in the thickening tank. The Company used the occasion of

the shutdown to advance multiple other projects, primarily in the crushing, grinding and carbon handling

circuits. Based on operating days during Q2 2025, mill throughput averaged approximately 8,500 tonnes

per day. Mill operating costs during Q2 2025 totaled $12.9 million for an average of $25.4 per tonne

processed. These costs are allocated to the mine operations based on a proportion of total tonnes

processed basis.

For the purpose of segment reporting, capital expenditures1 for Dome Mill and the TMA are allocated to

Hoyle Pond, Borden and Pamour based on a proportion of total tonnes processed basis. Capital

expenditures allocated during Q2 2025 totaled $16.5 million. The majority of these capital expenditures

related to the TMA, with work during the quarter largely focused on raising and buttressing the existing

dam walls and constructing seepage collection systems.

HOYLE POND

Hoyle Pond Mine is an underground gold mining operation located within the Archean Abitibi Greenstone

Belt approximately 20 km northeast of downtown Timmins, Ontario. Underground infrastructure includes

two decline ramps, an 815-metre four-compartment shaft (“#1 Shaft”) and a 1,350 metre winze (the “#2

Winze”) with the deepest station being on the 1600 -metre level. Underground production is trucked to

the #2 Winze and is then hoisted to the 720 level, where it is sent by tram to the loading pocket of the #1

Shaft. Mineralization is then trucked approximately 17 km to Dome Mill. The mine began operations in

1985 and, since that time, has produced over 4.0 million ounces of gold.

Gold production at Hoyle Pond from April 16, 2025, to June 30, 2025, totaled 16,112 ounces, which

resulted from 97,817 tonnes being processed at an average grade of 5.50 g/t and average recoveries of

93.1%. Production during the quarter was primarily from the Lower S Zone on the 1965 and 1985 levels.

A total of 45,160 tonnes were mined from April 16, 2025, to the end of Q2 2025, for an average mining

rate of 594 tonnes per day. During Q2 2025, 52,657 tonnes of stockpiled material from Hoyle Pond were

milled, which resulted in higher than planned tonnes milled for the quarter and a lower than expected

average grade. The Company does not anticipate processing significant amounts of low -grade stockpiles

from Hoyle Pond during the second half of 2025.

Operating development metres during Q2 2025 were mainly focused on the main production areas in the

Lower S Zone, as well as in areas of the Upper Mine, where production from narrow, high-grade veins is

expected to commence during the second half of 2025. Capital development activities during the quarter

mainly involved continuing to extend the main ramp to depth in the Lower S Zone.

Production costs, including mining and processing costs, in Q2 2025 totaled $20.9 million, with operating

cash costs averaging $1,566 per ounce sold1. AISC1 for the quarter averaged $2,036 per ounce sold, which

included $5.7 million of sustaining capital expenditures1, mainly related to capital development activities

as well as Hoyle Pond’s allocation of capital expenditures1 related to the TMA.

BORDEN

Borden Mine is a ramp access underground mine located on a 1,000 km 2 land position approximately 20

km east of Chapleau, Ontario. The deposit mine is located within the lower limb of an antiform in the

Borden Lake Greenstone Belt. Production at Borden commenced in 2019 and, to date, approximately

600,000 ounces have been produced. Mining is carried out at Borden using the longhole stoping method

with unconsolidated as well as cemented rock fill. Material is trucked from underground to surface and

then from the mine site approximately 190 km to the Dome Mill.

with capital development metres primarily related to the continued advancement of the main ramp and

the exploration drift on the 575 level.

Production costs in Q2 2025 totaled $22.0 million, with operating cash costs per ounce1 averaging $1,175

per ounce sold. AISC 1 averaged $1,621 per ounce sold for the quarter. Sustaining capital expenditures 1

totaled $9.0 million, with capital development accounting for $5.7 million and the remainder related to

allocated TMA expenditures, as well as investments in infrastructure, including an upgrade of the slurry

plant, and new equipment to optimize the mining fleet.

PAMOUR

Pamour mine, located approximately 20 km from downtown Timmins, first commenced underground

mining in 1911 and was operated until 1996. Open -pit mining operations were initiated in 2006 and

ceased in 2011. The project to re -develop and expand the Pamour open pit, and resume operations,

commenced in 2023, with initial production achieved early in 2025 and project contin uing to ramp up

towards commercial production levels.
