Bisichi Mining PLC (AIM:BISI) flew 46% higher on Friday in response to a glittering half-year report.
The small-cap coal miner saw a manifold increase in profit before tax, from £300,000 last year to £5 million.
Earnings per share escalated to 18.33p, from a 3.18p loss in the first half of 2023.
Bisichi attributed this to “a significant improvement in mining production and lower mining costs at Black Wattle Colliery, the Group’s South African mining operation”.
Total mining production from Black Wattle came to 708,000 metric tonnes compared to 354,000 metric tonnes in the first half of 2023, and 453,000 in the second half of that year.
Shares hit an eight-month high of 128p.
