The miner, who operates the Mpama North tine mine in the Democratic Republic of Congo, said its net cash for the quarter hit $129.51 million, having risen 90% year-on-year.
Alphamin produced 3,061 tonnes of tin and sold 3,336 tonnes. Production was down 2% year-on-year, but sales rose 9%.
The company achieved an average tin price during the three months of $43,813/t, which is up 14% year-on-year.
