1Information is disclosed on a 100% basis. Alphamin indirectly owns 84.14% of its operating subsidiary to which the information relates.2Q2 2026 EBITDA and AISC represent management's guidance. 3This is not a standardized financial measure and may not be comparable to similar financial measures of other issuers. See "Use of Non-IFRS Financial Measures" below for the composition and calculation of this financial measure. Apparent computational errors due to rounding are not considered significant.

Operational and Financial Performance

Contained tin production of 5,013 tonnes for the quarter ended June 2026 was in line with the target guidance of 20,000 tonnes per annum and that of the previous period. Tin sales of 5,014 tonnes were achieved compared to 5,016 in Q1 2026, resulting in the first four quarter rolling period of 20,000 tonnes achieved. Processing recoveries dipped 2% from 74.2% in Q1 2026, to 72.8% in Q2 2026. The metal sulphides in the current mining area are above average levels, and this resulted in excessive near gravity material interfering with the efficiency of the gravity circuit.

EBITDA for Q2 2026 is estimated at a record US$167m (Q1 2026: US$158m). The EBITDA variance compared to the prior quarter is attributable to a 5% increase in the tin price, from a US$49,278 average in Q1 2026, to US$51,957 average in Q2, 2026 (current price circa US$53,000). Guidance for AISC per tonne of tin sold in Q2 2026 is estimated at US$19,043, up 6% from the previous quarter of US$17,968 due to a combination of off-mine costs in the form of increased royalties, export duties, marketing commissions and net smelter returns, which increase as tin price increases, and timing on capital expenditure. On-mine operating costs increased largely as a result of higher fuel prices impacting diesel and transport costs. Fuel stocks have been and remain at full capacity with higher prices expected to continue into Q3 due to ongoing orders at elevated prices.

Alphamin's unaudited consolidated financial statements and accompanying Management's Discussion and Analysis for the three and six months ended 30 June 2026 are expected to be released on or about July 31, 2026.

Exploration update

Drilling Progress

Drilling continued in Q2, 2026 at Mpama North and South with mixed results;

A total of 5,547m (Q1 2026: 4,673m) was drilled (3,654m at Mpama South; 1,893m at Mpama North).

Mpama North

1,893m was drilled at Mpama North in Q2, with three holes completed and a further drill hole abandoned due to difficult ground conditions.

MND057D2_T7 Deflected from the MND057 mother hole. Intersected 1 metre of intense chlorite alteration with thin visible cassiterite mineralisation at 696m depth. Although thin, this is the deepest cassiterite intersection recorded at Mpama North to date, confirming that the tin mineralising system extends to at least this depth below surface. Sampling is underway with external laboratory assay results pending.

MND056BD4_T5 Deflected from the MND056B mother hole. Intersected 11 metres of amphibolite host rock from 609m, including 1 metre of intense chlorite alteration at 619m. No visible cassiterite mineralisation was intersected. The intersection is interpreted to be at or beyond the lateral margin of the mineralised corridor. This result informed the design of an up-dip deflection to re-test the mineralised envelope at a shallower position within the same structural corridor.

MND057D1_T6 Deflected from the MND057 mother hole. Intersected 3.5 metres of amphibolite host rock from 702m with moderate chlorite alteration. No visible cassiterite mineralisation was observed, consistent with the lateral margin of the mineralised system at this depth.

Mpama South

A total of 3,653.7m was drilled at Mpama South in Q2, with 5 holes completed and a further 2 abandoned due to difficult ground conditions.

The Mpama South orebody is hosted in the same north-south trending shear zone as Mpama North, approximately 300m to the south. Q2 drilling targeted extensions of the defined resource at depth, with three of five completed holes intersecting visible cassiterite mineralisation.

BGH206D2_T5 Visible cassiterite mineralisation observed over 19 metres, with intense chlorite and sulphide alteration from 427m depth. This is the most significant new intersection at Mpama South in the current programme. Two deflections from the BGH206 mother hole are planned at 275m and 230m depth to test continuity of mineralisation with the defined resource above. External laboratory assay results are pending.

BGH204D1 Visible cassiterite mineralisation observed over 17 metres, with intense chlorite and sulphide alteration from 524m depth. External laboratory assay results are pending.

BGH203D1 Visible cassiterite mineralisation observed in thin veins over 1.35 metres, with intense chlorite alteration from 577.85m depth. External laboratory assay results are pending.

BGH205D1 No visible cassiterite observed.

BGH208A No visible cassiterite observed.

External laboratory assays on previously disclosed holes were received and included below;

Mpama South: BGH196A_D1: 12.94m @ 2.10% Sn from 407.84m

Mpama North: MND056A_D1_T1: 0.81m @ 0.72% Sn from 567.63m

See Appendix 2 for additional assay results.

All intercepts are reported as apparent widths and are not true widths.

Future Initiatives

Airborne Survey: A VTEM (Versatile Time Domain Electromagnetic) airborne survey covering the full Alphamin licence area was completed in mid-June 2026. Interpretation of results is underway and expected to be delivered in Q3 2026. This is intended to provide advanced targets across ABM's license areas using the spatial association of sulphide mineralisation with cassiterite (tin).

Geochemical Surveys: Geochemical (soil) surveys commenced in Q2, to cover the Mpama Ridge north of the Oso River and all areas adjacent to basement rock units (similar geological settings to the Mpama Ridge which houses the Bisie deposit) with 13,000 samples planned for phase one of the survey which is expected to take six months to complete.

Downhole Geophysics: A downhole electromagnetic (EM) survey tool has been mobilised to site in Q2, 2026 and commenced operation in early Q3 2026. This will assist in mapping the apparent spatial association between massive sulphides and tin mineralisation in order to identify further resource extension drilling targets.

Further Extension Drilling: Further drilling is planned to test the gap between Mpama North and Mpama South, Mpama North depth extensions beyond the current faults and north of Mpama North as depicted by the white circles in image 1.

Resource and Reserve Update: The Company plans to release an updated resources and reserves estimate in Q4, 2026.

Liquidity and dividend update

The Company's Net Cash3 position was US$91m as at 30 June 2026 (31 March 2026: US$140m) after distributions to shareholders of US$160m (US$121m to shareholders of the Company, US$26m to minority shareholders in the Company's subsidiary in the DRC and US$13m in dividend withholding taxes in the DRC) and corporate tax payments of US$26m.

The Company intends to make a FY2026 interim dividend decision in Q4, 2026.

Security and health update

The regional security situation remains largely unchanged and operations continue as normal.

In Q2, 2026 an Ebola outbreak was declared in the Ituri province of Northeastern DRC. Whilst several cases have been reported in North Kivu, there have been none to date in the Walikale health zone, where the mine operates. The Company has implemented enhanced hygiene and screening protocols and expects operations to continue uninterrupted.

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/Debt

Net cash/(debt) demonstrates how our net cash/(debt) is being managed and is defined as net cash and cash equivalents less total current and non-current portions of debt and lease liabilities.

Appendix 1: SAMPLE PREPARATION, ANALYSES AND QUALITY CONTROL AND QUALITY ASSURANCE (QAQC)

Mpama North and Mpama South diamond drilling was completed from surface. The collar positions of the drillholes were accurately surveyed by Alphamin Bisie Mining (ABM) and down-hole surveys were completed by the drilling contractor allowing for accurate location of the mineralised intercepts. Cores were logged, mineralised intervals were identified and half core samples were taken at nominal 1 m intervals by the ABM geologists, which included the insertion of various certified reference material and blank samples (QAQC). No significant issues with the QAQC samples were noted. At the on-site ABM laboratory (managed by Anchem), samples were first checked off against the submission list supplied and then weighed and oven dried for 2 hours at 105 degrees Celsius. The dried samples were crushed by jaw crusher to 75% passing 2mm, from which a 250g riffle split was taken. This 250g split was pulverised in ring mills to 90% passing 75mum from which a sample for analysis was taken. Received samples at ALS Johannesburg are checked off against the list of samples supplied and logged in the system. Quality Control is performed by way of sieve tests every 50 samples and should a sample fail, the preceding 50 samples are ground in a ring mill pulveriser using a carbon steel ring set to 85 % passing 75mum. Samples are analysed for tin using method code ME-XRF05 conducted on a pressed pellet with 10% precision and an upper limit of 5,000ppm. The over-limit tin samples are analysed as fused disks according to method ME-XRF15c, which makes use of pre-oxidation and decomposition by fusion with 12:22 lithium borate flux containing 20% Sodium Nitrate as an oxidizing agent, with an upper detection limit of 79% Sn.
