ontréal, April 29, 2025 / Sydney, April 30, 2025 - Champion Iron Limited (TSX: CIA) (ASX: CIA) (OTCQX: CIAFF) (“Champion” or the “Company”)

reports production results and mining operating expenditures for its financial fourth quarter ended March 31, 2025. Detailed operational and

audited financial results are scheduled to be released prior to the Company hosting a conference call and webcast on May 29, 2025.

Champion’s CEO, Mr. David Cataford, said, “Our team’s agility and dedication were key to the successful completion of our scheduled semi-annual

maintenance program during the period. While scheduled maintenance was expected to temporarily impact production, it also provided an

opportunity to strategically reduce stockpiled iron ore inventories, despite seasonal logistical challenges. As global economies face uncertainties

with rising trade tensions, our Company benefits from robust financial liquidities and diversified global partners, enabling us to diligently advance

our growth initiatives.”

Conference Call Details

Champion will host a conference call and webcast on May 29, 2025, at 9:00 AM (Montréal time) / 11:00 PM (Sydney time) to discuss the results of

the financial fourth quarter ended March 31, 2025. Call details are set out at the end of this press release.

1. Quarterly Highlights

Operations and Sustainability

• During the three-month period ended March 31, 2025, no major environmental incidents were reported, but following a snowfall

incident that caused minor injuries, safety procedures were reviewed as part of the Company’s continuous improvement process;

• Quarterly prod uction of 3.2 million wmt (3.1 million dmt) of high-g rade 66.5% Fe concentrate for the three-m onth period ended

March 31, 2025, down 13% from the previous quarter, mainly attributable to the scheduled semi-a nnual shutdowns of both

concentration plants, and down 3% over the same period last year;

• Record quarterly sales of 3.5 million d mt for the three-month period ended March 31, 2025, up 6% from the previous q uarter and 18%

from the prior-year period due to the commissioning of additional rail equipment in the previous quarter, and despite winter conditions

that usually impact rail shipments;

2 Page

• Iron ore concentrate stockpiled at Bloom Lake decreased by 341,000 wmt quarter-over-quarter to 2.6 million wmt as at March 31, 2025,

as sales volumes exceeded production volumes during the quarter, benefiting from improved rail shipment capabilities. The Company

is confident that the iron ore concentrate currently stockpiled at Bloom Lake will continue to decrease in future periods; and

• Record material mined and hauled at Bloom Lake, totalling 20.4 million tonnes for the three-month period ended March 31, 2025, up 2%

from the previous quarter and 27% from last year.

Financial Results

• C1 cash cost for the iron ore concentrate delivered to Sept-Îles port facilities totalled approximately $80/dmt1 (US$56/dmt), an increase

of 2% quarter-over-quarter, and 4% year-on-year;

• Cash balance totalled $117.5 million as at March 31, 2025, an increase of $24.4 million since December 31, 2024, mainly resulting from

the reduction in iron ore concentrate stockpiled at Bloom Lake, while continuing to advance the DRPF project; and

• Available liquidity to support growth initiatives, including amounts available from the Company’s credit facilities, totalled $605.9 million1

at quarter-end, compared to $595.0 million1 as at December 31, 2024.

Growth and Development

• The DRPF project, designed to upgrade half of Bloom Lake’s capacity to DR quality pellet feed iron ore grading up to 69% Fe, is

progressing as planned, with the commissioning phase expected to start in December 2025;

• As part of the previously disclosed binding agreement to form a partnership (the “Partnership”) for the joint ownership and development

of the Kami Project (the “Transaction”) with Nippon Steel Corporation and Sojitz Corporation (collectively, the “Partners”), the Company

and the Partners have made progress towards finalizing the definitive documentation with respect to the Transaction. During the period,

Champion and the Partners advanced the definitive feasibility study for the Kami Project (the “DFS”) which is expected to be completed

in the end of calendar 2026; and

• The Company received financial support from the Government of Québec for the development of a technology using Bloom Lake’s iron

ore in battery production and for the development of innovative technologies and processes, including geometallurgical tools to improve

knowledge of mineral deposits and optimize the planning, concentration and production of high -purity iron. These two scientific

research projects highlight the rare high-purity of Bloom Lake’s iron ore and its potential to contribute to technologies beyond the green

steel supply chain.

2. Bloom Lake Mine Operating Activities

Bloom Lake produced 3.2 million wmt (3.1 million dmt) of high-grade iron ore concentrate during the three-month period ended March 31, 2025,

a decrease of 3% compared to 3.3 million wmt (3.2 million dmt) during the same period in 2024.

As expected, during the three-month period ended March 31, 2025, production was impacted for several days by the scheduled semi-annual

shutdowns of both concentration plants and adjustments to maintenance and recovery strategies caused by the adaptation to new ore feed

zones, in line with the Company’s long-term mine plan. Bloom Lake’s overall performance was also impacted by winter conditions, which primarily

affected transportation logistics and equipment availability.

During the three-month period ended March 31, 2025, Champion achieved record sales volumes attributable to the additional railcars and rolling

stock recently commissioned by the Company and the rail operator, respectively. Due to the scheduled semi-annual shutdowns, sales volumes

exceeded production, enabling the reduction in iron ore concentrate stockpiled at Bloom Lake by 341,000 wmt quarter-over-quarter to

2.6 million wmt as at March 31, 2025. The Company is confident that the iron ore concentrate currently stockpiled at Bloom Lake will continue to

decrease in future periods as Champion should continue to benefit from the recent improvement in rail shipment capabilities. Future destocking

of iron ore inventories is expected to occur at different rates considering the scheduled semi-annual maintenance work at the mine and on the

railroads, and the seasonal impact on transportation logistics. Champion continues to seek improvements from the rail operator in order to

receive contracted haulage services on a continued basis to ensure that Bloom Lake’s production, as well as the iron ore concentrate currently

3 Page

stockpiled at Bloom Lake, is hauled over future periods.

The Company’s focus remains to deploy work programs tailored to optimize operations and reliably produce at Bloom Lake’s nameplate capacity.

Additionally, Champion continues to analyze opportunities to structurally increase Bloom Lake’s nameplate capacity beyond 15 Mtpa over time.

To optimize operations, since the fourth quarter of the 2024 financial year, the Company has arranged for both plants’ scheduled maintenance

to occur in the financial second and fourth quarters. This creates significant quarter-over-quarter variances in production output, mining and

processing costs and inventory valuation at quarter-end.

During the three-month period ended March 31, 2025, the Company set a new record by mining and hauling 20.4 million tonnes of ore and waste

at Bloom Lake, exceeding the previous quarter’s output and surpassing last year’s volume of 16.0 million tonnes recorded during the same period

last year. This quarter-over-quarter improvement in mining performance was driven by the Company’s strategic investments in additional haul

trucks and loading equipment, as well as enhanced utilization and availability of mining equipment. Champion anticipates maintaining elevated

stripping activity levels in future periods, in accordance with its LoM plan.

The strong mining performance allowed the Company to mine and haul a higher volume of waste material, resulting in a stripping ratio of 1.15 for

the three-month period ended March 31, 2025, significantly higher than the 0.69 ratio recorded in the same prior-year period and the 0.94 ratio

in the previous quarter.

During the three -month period ended March 31, 2025, the two concentration plants at Bloom Lake processed 9.2 million tonnes of ore,

comparable to the same prior -year period. Although both periods were impacted by scheduled semi- annual shutdowns of the concentration

plants, the volumes processed during the three-month period ended March 31, 2025, remained adversely impacted by ore hardness and limited

milling capacity.

The iron ore head grade for the three-month period ended March 31, 2025, was 29.2%, comparable to the same period in 2024 . The variation in

head grade was within the anticipated range of normal fluctuations outlined in the mine plan.

Champion’s average Fe recovery rate was 78.3% for the three-month period ended March 31, 2025, compared to 80.2% for the same period in

2024. This decrease was primarily attributable to the geological sequence encountered since the previous quarter. The normal evolution of the

mine plan required adjustments to ore blending strategies, hardness management and recovery circuits. The Company continues to optimize its

operations and remains focused on improving and stabilizing recovery rates over time, despite the expectation that ore hardness challenges will

persist in the coming months.

3. Mining and Processing Operating Expenditures

For the three -month period ended March 31, 2025, the cost of sales totalled approximately $280 million with a C1 cash cost of $8 0/dmt1,

compared to $227.5 million with a C1 cash cost of $76.6/dmt1 for the same period in 2024, and $258.7 million with a C1 cash cost of $78.7/dmt1

4 Page

for the previous quarter.

C1 cash cost for the three-month period ended March 31, 2025, was impacted by higher mining and processing costs, primarily driven by slightly

higher costs related to the scheduled semi -annual shutdowns performed at both concentration plants , higher stripping activities aligned with

the long-term mine plan, and additional maintenance on crushers and grinding circuits that experienced premature wear due to the hardness of

the ore processed. The increase in mining and processing costs was partially offset by lower land transportation and port handling costs, mainly

attributable to the rail operator’s semi-annual fuel price indexation and increased sales volumes during the period to amortize fixed costs at the

Sept-Îles port facilities.

4. Exploration Activities

During the three-month period ended March 31, 2025,

• the Company maintained all its properties in good standing and no farm-in or farm-out arrangements came into effect. Subject to final

negotiations and the execution of definitive transaction documents, the Partners agreed to jointly conduct and fund certain components

of the Kami Project’s DFS on a pro -rata basis, in accordance with their respective ownership interests. Expected reimbursements of

expenditures already incurred by Champion pursuant to the existing collaboration agreement with the Partners were deducted from

exploration and evaluation assets;

• approximately $11 million was incurred in exploration and evaluation expenditures, compared to $1.6 million for the same prior -year

period; and

• exploration and evaluation expenditures were related to activities carried out in Québec and Newfoundland and Labrador.

About Champion Iron Limited

Champion, through its wholly-owned subsidiary Quebec Iron Ore Inc., owns and operates the Bloom Lake Mining Complex located on the south

end of the Labrador Trough, approximately 13 km north of Fermont, Québec. Bloom Lake is an open -pit operation with two concentration plants

that primarily source energy from renewable hydroelectric power, having a combined nameplate capacity of 15M wmt per year that produce low

contaminant high-grade 66.2% Fe iron ore concentrate with a proven ability to produce a 67.5% Fe direct reduction quality iron ore concentrate.

Benefiting from one of the highest purity resources globally, Champion is investing to upgrade half of Bloom Lake’s mine capa city to a direct

reduction quality pellet feed iron ore with up to 69% Fe. Bloom Lake’s high-grade and low contaminant iron ore products have attracted a premium

to the Platts IODEX 62% Fe iron ore benchmark. Champion ships iron ore concentrate from Bloom Lake by rail, to a ship loading port in Sept-Îles,

Québec, and has delivered its iron ore concentrate globally, including in China, Japan, the Middle East, Europe, South Korea, India and Canada. In

addition to Bloom Lake, Champion owns the Kamistiatusset mining properties, a project with an estimated annual production of 9M wmt per year

of direct reduction quality iron grading above 67.5% Fe, located near available infrastructure and only a few kilometres south-east of Bloom Lake.

In December 2024, Champion entered int o a binding agreement with Nippon Steel Corporation and Sojitz Corporation to form a partnership to
