Operational and Financial Performance

Alphamin achieved record tin production of 12,493 tonnes for the year ended December 2022, exceeding market guidance of 12,000 tonnes. Underground mining performed particularly well with both volumes and tin grades exceeding expectations. The processing plant achieved good recoveries at an average of 75%. A highly mineralised area underground, not previously included in the mineral resource or mine plan due to its structurally complex nature, was successfully mined and processed during Q3 and Q4 2022. This area delivered ore at good tin grades but contained high levels of sulphides which impacted processing recoveries.

Contained tin production of 3,113 tonnes for Q4 2022 was in line with the previous quarter and above market guidance of 3,000 tonnes.

Sales volumes for FY2022 and Q4 were in line with production at an average achieved tin price of US$30,636/t and US$21,436/t, respectively. We expect contained tin production and sales of approximately 12,000 tonnes for the year ending December 2023.

AISC per tonne of tin sold remained relatively flat year-on-year at US$14,289/t in FY2022.

EBITDA for FY2022 and Q4 2022 is estimated at US$222m (2021: US$198.6m) and US$27.1m (Q3: US$30m), respectively. The record estimated FY2022 EBITDA saw an average tin price achieved of US$30,636/t, in line with current tin prices of around US$30,000/t. The Company remains of the opinion that global tin supply is likely to be constrained during the next five years while demand for tin is expected to increase. In light of these market fundamentals, the development of the Mpama South project and consequent planned production expansion to approximately 20,000 tonnes of contained tin per year bodes well for future cash flow generation. The Mpama South project development remains on track for commissioning in December 2023.

The Alphamin consolidated Net Cash position of US$109 million at year-end is after dividend payments of US$71.5m to Alphamin shareholders and minority shareholders of the operating mine, US$30m cash applied towards the development of the Mpama South project, US$16.7m spent on exploration activities and DRC taxes paid of US$49.4m. Capital allocation during FY2023 will be prioritised towards the development of the Mpama South project, DRC income tax payments and shareholder distributions.

Alphamin’s audited consolidated financial statements and accompanying Management’s Discussion and Analysis for the year and quarter ended 31 December 2022 are expected to be released on or about March 13, 2023.

Final FY2022 Dividend Declared

The Board has declared a final FY2022 cash dividend of CAD$0.03 per share on the common shares (approximately US$28.7m in the aggregate). The Dividend will be payable on 10 March 2023 to shareholders of record as of the close of business on 24 February 2023. Together with the interim FY2022 dividend of CAD$0.03 per share declared on 5 July 2022, the total FY2022 dividends declared amount to CAD$0.06 per share.
