Imperial Reports Second Quarter 2026 Financial Results

Vancouver | August 6, 2026 | Imperial Metals Corporation (the “Company” or “Imperial”) (TSX:III) reports financial results for

the three and six months ended June 30, 2026. Imperial’s consolidated production for the second quarter of 2026 totalled

8,759,242 pounds copper and 11,226 ounces gold.

“We completed a very strategic quarter for Imperial as both mines, Mount Polley and Red Chris, received key authorizations

that extend their permitted mine life. At Mount Polley, we worked through some lower grade ore to position the operation

for access to higher grade mineralization that will be exposed for mining later this year” , said the President, Brian Kynoch.

“Supported by good copper and gold prices, we continue d investing in our operations even during this period of lower

grades from both mines. The permits received for the tailing dam raise at Mount Polley and transition to block cave mining

at Red Chris position the Company to deliver returns in the coming years.”

FINANCIAL

Total revenue was $166.5 million in the June 2026 quarter compared to $175.8 million in the 2025 comparative quarter.

In the June 2026 quarter, Mount Polley mine had 1.0 concentrate shipments (202 5-1.9 concentrate shipments). The Red

Chris mine (100% basis) had 4.0 concentrate shipments (2025-5.0 concentrate shipments).

Variations in revenue are impacted by the timing and quantity of concentrate shipments, metal prices and exchange rates,

and period end revaluations of revenue attributed to concentrate shipments where copper and gold prices will settle at a

future date.

At June 30, 2026, the Company had not hedged any copper, gold or US/CDN Dollar exchange.

Revenue revaluation for the June 2026 quarter was $4.6 million, compared to $2.2 million in the comparative quarter of

2025. Revenue revaluations arise from changes in metal prices between the initial recognition of revenue and the settlement

date and/or t he reporting balance sheet date, together with adjustments to payable metal quantities following receipt of

final assay results.

Net income for the June 2026 quarter was $22.0 million ($0.12 income per share) compared to net income of $40.6 million

($0.25 income per share) in the 2025 comparative quarter. The decrease in net income of $18.6 million was primarily due

to the following factors:

• Income from mine operations decreased to $47.3 million in the June 2026 quarter from $81.3 million in the June 2025

quarter, a decrease of $34.0 million, partially offset by:

• Net interest expense decreased to $3.6 million in the June 2026 quarter from $6.8 million in the June 2025 quarter,

increasing net income by $3.2 million; and

• Tax expense decreased to $13.5 million in the June 2026 quarter from $26.5 million in the June 2025 quarter, increasing

net income by $13.0 million.

Capital expenditures including leases were $ 67.0 million in the June 2026 quarter, a n increase of $2.9 million from $ 64.1

million in the 2025 comparative quarter. The June 2026 quarter expenditures included $ 29.8 million in exploration and

development, $12.4 million for tailings dam construction and $24.8 million of other capital.

OPERATIONS

During the quarter ended June 30, 2026, Imperial’s consolidated metal production was 8.8 million pounds copper (Q2 2025-

16.5 million pounds copper) and 11,226 ounces gold (Q2 2025-17,848 ounces gold).

Mount Polley Mine

Mount Polley metal production for the second quarter of 202 6 was 3.382 million pounds copper and 6,848 ounces gold,

compared to 9.496 million pounds copper and 11,061 ounces gold produced during the second quarter of 202 5. Copper

production was down 64% and gold production was down 38%, on lower grades, recoveries and throughput compared to

the second quarter of 2025. Throughput in the second quarter of 2026 was 18,498 tonnes per day compared to 19,331

tonnes per day in the second quarter of 2025. Compared to the first quarter of 202 6, throughput was up 12%, copper

production was down 23% and gold production was down 10%.

Gold - ounces 6,848 11,061 14,457 21,682

Mill feed for the second quarter of 2026 was sourced 44% from the Springer pit Phase 5 pushback supplemented by 15%

from Phase 4 and C2 pit, and 41% from lower grade stockpiles. The high percentage of low -grade stockpile material

delivered to the mill resu lted in lower copper and gold grades being milled. By the fourth quarter of 2026 higher grade

material from Phase 5 should begin to be delivered to the mill and reduce or eliminate the need to process lower grade

stockpiles.

Stripping activities for the Phase 5 pushback continued during the quarter with approximately 6.032 million tonnes of rock

mined from this pushback. Approximately 2.725 million tonnes of non -acid generating rock from the pushback were

delivered to the tailings storage facility embankment for buttress construction.

Exploration program

Diamond drilling started in February 2026 and initially followed up on the successful results from the first drilling campaign

at the Mount Polley mine in more than a decade in the Bell Pit area. Since February 2026, there have been 41 diamond drill

holes completed totaling 8,620 metres focusing on the historic Bell Pit area, the expansion of the Cariboo Zone laterally and

to depth.

Exploration, development, and capital expenditures in the second quarter of 2026 were $30.3 million compared to $ 33.7

million in the 2025 comparative quarter.

Red Chris Mine

Red Chris production (100%) for the second quarter of 2026 was 17.924 million pounds copper and 14,591 ounces gold

compared to 23.479 million pounds copper and 22,624 ounces gold during the same quarter of 2025. Both copper and gold

production were down compared to the second quarter of 2025, with copper production down 24% and gold production

down 36%.

The decrease in copper production was a result of a 1 8% decrease in copper grade (0.45% vs. 0.55%) with higher recovery

and lower throughput. The decrease in gold production was a result of lower gold grade in the mill feed (0. 35 g/t gold vs.

0.49 g/t gold) and lower throughput, with similar gold recovery (59.4% vs. 60.0%) compared to the same quarter last year.

Both copper and gold production remain on track to achieve the budgeted 2026 production, and the guidance for 2026 Red

Chris production (100%) remains 60.0 – 66.0 million pounds of copper and 47,500 – 52,500 ounces of gold.

Imperial’s 30% share of exploration, development, and capital expenditures were $ 35.0 million in the June 2026 quarter

compared to $30.2 million in the 2025 comparative quarter.

Block Cave Feasibility Study

The Red Chris feasibility study for a block cave expansion operation is advancing. The key permits are in hand with approval

from both the Province of British Columbia and Tahltan First Nation. Completion of the feasibility study and, subject to the

study outcomes, joint venture approval are expected in the second half of 2026.

Exploration Program

There have been three diamond drills operating at Red Chris during the last quarter, one underground for geotechnical

information and two surface drills completing geotechnical information for the proposed block cave and exploration in the

Far West zone. A dditional surface drilling will be continuing in the Far West zone and then the drill rig will be moving to

explore the South Boundary fault offset Main zone target. There will be continued surface exploration outside of the known

zones along strike of the Red Chris porphyry stock.

Huckleberry Mine

Huckleberry operations ceased in August 2016 and the mine remains on care and maintenance status.

Following the successful drilling program in 2025 of an underexplored area southwest of the Main Zone Pit, where all nine

drillholes intersected copper, molybdenum, silver, and gold mineralization, a program of re-assaying available historic core

for gold and silver was completed. A follow -up 2026 drilling program included drilling additional 22 diamond drill holes,

with all the holes intersecting significant copper, molybdenum, silver and gold.

The Company has commenced preliminary work on the cost of restarting Huckleberry and is targeting to have a completed

reopening plan by the end of 2026 that includes a mine plan optimized with the new diamond drilling data.

For the June 2026 quarter, Huckleberry incurred idle mine costs comprised of $2.6 million in operating costs and compared

to $1.7 million in operating cost and $0.3 million in depreciation expense in the comparable quarter of 2025.

Exploration, development, and capital expenditures were $0.9 million in June 2026 quarter compared to $0.1 million in

June 2025 quarter.

NON-GAAP FINANCIAL MEASURES

The Company reports on four non-GAAP financial measures: adjusted net income, adjusted EBITDA, cash earnings and cash

cost per pound of copper produced, which are described in detail below. The Company believes these measures are useful

to investors because they are included in the measures that are used by management in assessing the financial performance

of the Company.

Adjusted net income, adjusted EBITDA, cash earnings and cash cost per pound of copper are not standardized financial

measures under IFRS Accounting Standards and might not be comparable to similar financial measures disclosed by other

issuers.

Adjusted Net Income and Adjusted Net Income Per Share

Adjusted net income is derived from operating net income by removing the gains or loss es, resulting from acquisition and

disposal of property , net of tax, unrealized foreign exchange gains or losses on long term debt, net of tax and other non -

recurring items. Adjusted net income in the June 2026 quarter was $22.6 million ($0.13 per share) compared to an adjusted

net income of $40.6 million ($0.25 per share) in the 2025 comparative quarter. We believe that the presentation of Adjusted

Net Income helps investors better understand the results of our normal operating activities and the ongoing cash generating

potential of our business.

Adjusted EBITDA

Adjusted EBITDA in the June 2026 quarter was $70.0 million compared to $ 99.5 million in the 2025 comparative quarter.

We define Adjusted EBITDA as net income before interest expense, taxes, depletion, and depreciation, and as adjusted for

certain other items.

Cash Earnings and Cash Earnings Per Share

Cash earnings in the June 2026 quarter was $69.2 million compared to $97.7 million in the 2025 comparative quarter. Cash

earnings per share was $0.39 in the June 2026 quarter compared to $0.60 in the 2025 comparative quarter.

Cash earnings and cash earnings per share are measures used by the Company to evaluate its performance ; however, they

are not terms recognized under IFRS Accounting Standards . We believe that the presentation of cash earnings and cash

earnings per share is appropriate to provide additional information to investors about how well the Company can earn cash

to pay its debts and manage its operating expenses and investment. Cash earnings is defined as cash flow from operations

before the net change in non-cash working capital balances, income and mining taxes paid, and interest paid. Cash earnings

per share is the same measure divided by the weighted average number of common shares outstanding during the year.

Cash Cost Per Pound of Copper Produced

Management uses this non-GAAP financial measure to monitor operating costs and profitability. The Company is primarily

a copper producer and therefore calculates this non-GAAP financial measure individually for its two operating copper mines,

Mount Polley and Red Chris (30% share), and on a composite basis for these mines.

Variations from period to period in the cash cost per pound of copper produced are the result of many factors including:

grade, metal recoveries, amount of stripping charged to operations, mine and mill operating conditions, labour and other

cost inputs, transportation and warehousing costs, treatment and refining costs, the amount of by -product and other

revenues, the US$ to CDN$ exchange rate and the amount of copper produced .
