CAUTION REGARDING FORWARD LOOKING STATEMENTS

Article content

Information in this news release that is not a statement of historical fact constitutes forward-looking information. Forward-looking statements contained herein include, without limitation, Q3 2025 EBITDA and AISC guidance and FY2025 contain tin production guidance, estimated Q4 2025 contained tin production and estimated timing for the completion of the current two Mpama South drill holes in progress. Such statements reflect the current views of the Company with respect to future events and are subject to certain risks, uncertainties and assumptions. Many factors could cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements that may be expressed or implied by such forward-looking statements. Such factors include, without limitation: the availability of ore at expected quantities and grades, uninterrupted processing of ore at targeted processing recoveries, uncertainties regarding logistics and the timing of supplier responses to orders; uncertainties with respect to social, community and environmental impacts, adverse political events and risks of security related incidents or threats of security related incidents which may impact the operation or cause a stop to mine activities, outbound roads used to transport product and consumables or the safety of our people, uncertainties regarding the legislative requirements in the Democratic Republic of the Congo which may result in unexpected fines and penalties and tax payments; the speculative nature of mineral exploration and development as well as “Risk Factors” included elsewhere in Alphamin’s public disclosure documents filed on and available at www.sedarplus.ca.

USE OF NON-IFRS FINANCIAL PERFORMANCE MEASURES

Article content

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

Article content

EBITDA

Article content

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.

Article content

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

Article content

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.

Article content

AISC

Article content

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.

Article content

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.

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

Article content

Mpama North diamond drilling was completed from underground 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 75μm 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 75μm. 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.
