Operational and Financial Performance

Contained tin production of 5,008 tonnes for the quarter ended December 2025 was in line

with the targeted quarterly production of 5,000 tonnes and 4% lower than the prior quarter.

The tin grade of ore processed for the quarter was higher than planned and, as a result,

throughput was reduced to balance contained tin in the plant. The processing facilities

achieved recoveries of 73% for the quarter, below the target of 75% and impacted by higher

than usual feed grade fluctuations.

For the year ended 31 December 2025, the Company produced 18,576 tonnes of contained

tin, substantially in line with revised guidance (18,000 – 18,500 tonnes) and 7% above that of

the previous year. Overall processing recoveries for the financial year were in line with target

at 75%. FY2025 tin production was impacted by the temporary cessation of operations related

to security concerns in March 2025 and the phased restart from 15 April 2025. The Company

achieved a pro-forma annualised run-rate of approximately 20,000 tonnes contained tin

produced during FY2025 when adjusted for the period during which operations were

temporarily ceased.

Tin sales volumes for Q4 2025 and FY2025 were 5,045 tonnes and 18,638 tonnes,

respectively, in line with production.

Q4 2025 AISC per tonne of tin sold was US$16,815 at 5% above the prior quarter’s AISC of

US$15,978, primarily due to an increase in the diesel prices due to additional taxes imposed

by the DRC government and an increase in marketing fees, which increase from 2.25% to

3.35% above a $40,000 tin price. The Q4 2025 tin price achieved of US$37,995/t was 12%

higher than the previous quarter. The current tin price is trading at approximately US$50,000/t

– for illustrative purposes, at this higher tin price off-mine costs are expected to increase by

~US$1,500/t net of lower 2026 smelter charges.

EBITDA for the year ended 31 December 2025 increased by 25% to US$341m (FY2024:

US$274m) due to higher tin production and sales volumes which included a full year from the

Mpama South expansion which was completed mid 2024 as well as a 13% increase in the

average tin price to US$34,373/t (current tin price: ~US$50,000/t). The Q4 2025 EBITDA of

US$108m is 13% above that of the previous quarter mainly due to a 12% higher tin price

achieved.

The Company had US$56m in cash at 31 December 2025 (prior year: US$30m) after debt

reduction and service costs of US$45m, DRC tax payments of US$106m and total FY2025

dividend payments of US$123m. The current tin price and continued steady production bode

well for increased cash flow generation and the potential for higher dividends to shareholders.

During FY2025, Alphamin Resources declared dividends totalling CAD$0.11 per share

compared to CAD$0.09 in FY2024. The next dividend decision is targeted for the end of April

2026 following finalisation and approval of the Company and its DRC operating subsidiary’s

audited financial statements for the year ended December 2025.

Production guidance for the year ending December 2026

Production guidance for the year ending December 2026 is approximately 20,000 tonnes of

contained tin (FY2025: 18,576 tonnes).

Exploration update

Alphamin’s exploration strategy is built on three key objectives:

1. Expand the Mpama North and Mpama South resource base to extend mine life.

2. Discover the next tin deposit near the Bisie mine.

3. Continue grassroots exploration across our large, highly prospective land package.

The Company has hired Mr Jamie Anderson as its Head of Exploration effective 01 March

2026. Jamie spearheaded the Mpama North drilling campaigns from the initial exploration in

2012 through to 2018, as well as the Mpama South drilling from 2020 to 2021.

Alphamin is investigating implementing downhole electromagnetic (EM) surveys to use the

apparent spatial association between massive sulphide mineralisation, that typically occurs in

the hanging wall, and tin mineralisation in order to locate resource extension drilling targets.

In order to advance its regional exploration initiatives, a VTEM (Versatile Time Domain

Electromagnetic) survey, which is an airborne geophysical survey method, is planned for the

entire license package area which will commence at the end of March 2026, with a view to

identifying additional exploration/drill targets.

The Company currently has three drill rigs operating at site with a fourth scheduled to

commence drilling in mid-March. The Company plans to execute a substantial drilling

campaign throughout 2026.

Security Risk

The Company continuously monitors the security situation. At this time, the Company

continues to operate within guidance parameters. As a result of the ongoing security risks in

the area, the operating risk profile remains elevated and a sustained advance closer to the

mine location could result in mining operations being affected. The safety of the Company’s

employees and contractors and compliance with the DRC and international laws remains our

committed focus.

Award of Stock Options and Share Appreciation Right Equivalent Shares

On March 11, 2026, the Company awarded, subject to regulatory approval, stock options and

SAR Equivalent Shares pursuant to its Omnibus Incentive Plan. The Company has granted

stock options to acquire an aggregate of 4,100,000 common shares to employees and

directors of an Alphamin subsidiary, with each option exercisable for a seven-year term to

acquire one common share at a price of C$1.26 per share. 3,300,000 of the options granted

vest over a two-year period from the date of grant. 800,000 of the options granted vest over a

three-year period from the date of grant.

The Company also authorized the issuance of 1,683,000 SAR Equivalent Shares (“SARES”)

to two senior officers of the Company. The SARES are functionally equivalent to stock

appreciation rights however, any entitlements are satisfied by dividend payments on the

SARES. The reference price for the SARES awarded is C$1.26 and dividends shall be payable

on the SARES (to the extent that they are “in-the-money”) on the first, second and third

anniversaries of the date of award.

USE OF NON-IFRS FINANCIAL PERFORMANCE MEASURES

This announcement refers to the following non-IFRS financial performance measures:

EBITDA

EBITDA is profit before net finance expense, income taxes and depreciation, depletion, and

amortization. EBITDA provides insight into our overall business performance (a combination

of cost management and growth) and is the corresponding flow driver towards the objective of

achieving industry-leading returns. This measure assists readers in understanding the ongoing

cash generating potential of the business including liquidity to fund working capital, servicing

debt, and funding capital and exploration expenditures and investment opportunities.

This measure is not recognized under IFRS as it does not have any standardized meaning

prescribed by IFRS and is therefore unlikely to be comparable to similar measures presented

by other issuers. EBITDA data is intended to provide additional information and should not be

considered in isolation or as a substitute for measures of performance prepared in accordance

with IFRS.

CASH COSTS

This measures the cash costs to produce and sell a tonne of contained tin. This measure

includes mine operating production expenses such as mining, processing, administration,

indirect charges (including surface maintenance and camp and head office costs), and

smelting, refining and freight, distribution and royalties. Cash costs do not include depreciation,

depletion, and amortization, reclamation expenses, capital sustaining, borrowing costs and

exploration expenses. On mine costs, exclusive of stock movement, are calculated on a cost

per tonne produced basis, off mine costs are calculated on a cost per tonne sold basis.

AISC

This measures the cash costs to produce and sell a tonne of contained tin plus the capital

sustaining costs to maintain the mine, processing plant and infrastructure. This measure

includes the Cash Cost per tonne and capital sustaining costs together divided by tonnes of

contained tin produced. All-In Sustaining Cost per tonne does not include depreciation,

depletion, and amortization, reclamation, borrowing costs, foreign exchange gains and losses,

exploration expenses and expansion capital expenditures.

Sustaining capital expenditures are defined as those expenditures which do not increase

payable mineral production at a mine site and excludes all expenditures at the Company’s

projects and certain expenditures at the Company’s operating sites which are deemed

expansionary in nature.
