Operational and Financial Performance

Contained tin production of 5,237 tonnes for the quarter ended December 2024 was 7% above the prior period. The volumes and tin grade of ore processed were slightly above that of the previous quarter and in line with the annualised target of 900,000 tonnes at a grade of 3%. The processing facilities performed exceptionally well – overall plant recoveries averaged 75% during the quarter, above the target of 73%. For the year ended 31 December 2024, the Company produced 17,324 tonnes of contained tin, 38% above that of the previous year and within the guidance range of 17,000 to 18,000 tonnes. This increase is a result of production from the Mpama South expansion which was completed during Q2 2024.

Tin sales volumes for the quarter decreased by 11% to 4,942 tonnes – the previous quarter’s sales of 5,552 tonnes included the clearing of a ~600 tonnes sales backlog. As has historically been the case, Q4 experienced high rainfall which impacted the outbound road conditions and transit times and as a result sales volumes for Q4 were 295 tonnes below tin volumes produced with the backlog expected to clear during January 2025.

Q4 guidance for AISC per tonne of tin sold is US$15,106 at 4% below the prior quarter’s actual AISC of US$15,728, primarily due to a ~60% reduction in marketing fees as a condition to the previously announced extension of the tin concentrate off-take agreement with Gerald Metals.

EBITDA for the year ended 31 December 2024 is estimated to increase by 102% to US$274m (FY2023 actual: US$136m) due to higher tin production and sales volumes following the Mpama South expansion as well as the benefit of a 17% increase in the average tin price to US$30,345/t. The Q4 EBITDA guidance of US$76m is 17% below the actual of the previous quarter due to lower sales volumes for the reasons outlined above as well as a 4% lower tin price.

Alphamin’s audited consolidated financial statements and accompanying Management’s Discussion and Analysis for the year and quarter ended 31 December 2024 are expected to be released on or about March 14, 2025.

Production guidance for the year ending December 2025

Production guidance for the year ending December 2025 is approximately 20,000 tonnes of contained tin (FY2024: 17,324 tonnes) with the full year expected to benefit from the Mpama South expansion.

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 surface drilling campaign at Mpama South targeting both down-dip, up-dip and strike extensions is underway with three 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.

Mpama North

A short 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. Two more step-out holes are planned from underground targeting these strike and dip extensions, after which surface drilling targeting further dip and strike extension is planned.

Forward-looking statements are based on assumptions management believes to be reasonable at the time such statements are made. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

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.
