JSE-listed tin concentrate producer Alphamin Resources has increased its tin production by 29% quarter-on-quarter to 2 739 t, while also managing to reduce its all-in sustaining costs (AISC) by 13% to $10 849/t.
Alphamin operates the Bisie tin mine, in the Democratic Republic of Congo, and attributes the higher production, which is better than previous market guidance, on its better-than-expected tin feed grades.
