Mustang hopes for more ruby sales in October

Ruby miner Mustang Resources is on track to store some 200 000 carats of inventory at its Montepuez project, in Mozambique, ahead of a planned auction in October. The ASX-listed junior told shareholders that a current A$1-million plant upgrade has been highly successful, allowing processing grades to ramp up. The upgraded plant is designed to achieve a throughput rate of 250 t/h, with Mustang saying that it would initially operate the plant for one seven-hour shift a day.
