Operational and Financial Performance

Contained tin production of 4,106 tonnes for the quarter ended June 2025 was below the

targeted quarterly production of 5,000 tonnes due to the impact of the temporary cessation of

operations on 13 March 2025 related to security concerns and the phased restart from 15 April

2025. The months of May and June 2025 recorded contained tin production of 3,361 tonnes

which was in line with the annualised target of 20,000 tonnes. The processing facilities

performed well and above target – overall plant recoveries averaged 77% during the quarter

(Q1: 75%).

Q2 2025 contained tin sales of 4,587 tonnes was recorded against production of 4,106 tonnes

as the sales backlog from Q1 was cleared. The average tin price achieved was in line with the

prior quarter at US$32,512/t – the tin price is currently trading at around US$33,700/t.

Q2 2025 AISC per tonne of tin sold is estimated at US$16,500 (Q1: US$16,279) which is higher

than under normal operating conditions due to the impact of the operational stop on 13 March

2025 and subsequent restart during the second half of April 2025. Operating expenditures

included fixed costs and payroll for the full quarter as well as care and maintenance and mine

restart costs while tin production recommenced in a phased manner from 15 April 2025.

EBITDA guidance for Q2 2025 is US$75m, 21% higher than the previous quarter’s actual of

US$62m. This increase is primarily due to additional tin sales during Q2 2025 which included

clearing of the backlog experienced during the prior quarter.

The Company had US$110m in cash at 30 June 2025 after settlement of its FY2024 final DRC

tax payment of US$38m at end April 2025, a reduction of its overdraft balance by US$14m to

US$39m and payment of the first FY2025 provisional DRC tax instalment of US$14m. The Net

Cash position of US$50m improved by US$52m from a Net Debt position of US$2m the prior

quarter. During Q2 2025, the Company recommenced utilisation of a portion of its tin

prepayment arrangement with offtaker Gerald Metals.

Exploration update

Alphamin’s exploration strategy focuses on three key objectives:

1. Increase the Mpama North and Mpama South Resource base and life of mine

2. Discover the next tin deposit in close proximity to the Bisie mine

3. Ongoing grassroots exploration in search of remote tin deposits on the large

prospective land package

Exploration drilling at Mpama North and Mpama South re-commenced during Q4 2024.

Mpama South

A single rig surface drilling campaign at Mpama South targeting both down-dip, up-dip and

strike extensions is underway with four holes completed to date. The first two holes to the far

south of the current mineralised zone designed to test the lower grade southern extents did

not intersect visual tin mineralisation. The subsequent holes were planned 50-80m below the

current resource boundary and at depth. The first of these holes (BGH191A) intercepted

multiple narrow cassiterite veins 82m below the current Resource boundary over three zones

of 9.04 m, 0.86m and 1.04m that potentially extends the mineralised system. The next two of

these drillholes (BGH192 and BGH193) were completed with BGH192 intersecting visible

cassiterite veins and BGH193 not intersecting any visible cassiterite. Hole BGH194 was drilled

and completed during Q2 2025 and intercepted visible cassiterite veins further north of

BGH193 and below the current Resource.

Mpama North

A single rig exploration campaign of geological fan drilling from underground at Mpama North

on the northern open extensions of the mineralised zone started in Q4 2024. This campaign

was aimed at better understanding the geological structure in this area. These eight holes

totalling 1,525m, intersected a number of chlorite alteration zones associated with tin

mineralisation as well as minor cassiterite veins. One hole in particular intersected wide zones

of massive sulphides which are frequently used as a hanging wall marker horizon potentially

indicating further cassiterite mineralisation at depth.

The next drill holes at Mpama North are targeting an extension to mineralisation at depth along

strike to the north. The first of these drillholes (MNUD008A) was completed in early January

2025 and intersected a thick chlorite altered zone of visual tin cassiterite approximately 20m

north of the previously most northerly Resource drillhole and some 200m below the bottom of

the current mining echelon. The second of these planned drillholes (MNUD009) also

intersected a thick zone of significant visual tin cassiterite a further ~20m north of drillhole

MNUD008A. The third drillhole on strike was completed in Q1 2025 without a visual cassiterite

intersection.

The Company will be flying a dedicated surface drill rig to site to commence with drilling for

extensions of the Mpama North deposit at depth.

The Company expects to release external laboratory assays for exploration drilling to date

during Q3 2025.

Amendments to Constitution

The Company has filed an amended Constitution with the Registrar of Companies (Mauritius)

that contains certain changes to its Constitution relating to the election, appointment and

removal of directors and the declaration and payment of dividends, to clarify these provisions

approved by shareholders by special resolution at the Company’s annual general and special

meeting held on June 18, 2025 (the “Meeting”). Full details of the amendments are contained

in the Company’s management information circular dated May 8, 2025 furnished in connection

with the Meeting and a copy of the full amended Constitution will be filed under the Company’s

profile on SEDAR+ at www.sedarplus.ca once the filing is approved by the Registrar.

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.

NET CASH/ NET DEBT

Net Cash demonstrates how our debt is being managed and is defined as cash and cash

equivalents less total current and non-current portions of interest-bearing debt and lease

liabilities.

Neither the TSX Venture Exchange nor its regulation services provider (as that term is defined

in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or

accuracy of this news release.
