Coal miner Stanmore Coal has completed its debt refinancing, aimed at reducing the overall cost of financing. The ASX-listed company on Monday said that it had extended the term of an existing facility with financier Taurus from November 15 this year until the end of June 2022, and has increased a working capital facility from $22-million to $28-million, to match the company’s larger business scale following an increase in production from 1.2-million tonnes to 2.3-million tonnes a year.
