adminreported in its latest quarterly report.
Zimbabwe-based Mimosa is a 50-50 joint venture between Implats and Aquarius Platinum, which are both domiciled in neighbouring South Africa.
Implats said Mimosa will maintain this production level for the next five years supported by capital expenditure of about US$35 million a year.
Higher-than-anticipated labour costs, material use, consumable costs and a stronger rand adversely impacted unit costs at the platinum mining firm.
But Mimosa produced a record 104 900 ounces of platinum in concentrate for the 2010/11 financial year, noted Implats in its integrated annual report for the 2010/2011 financial year.
Milled tonnage increased by 1 percent to 2,3 million tonnes, while concentrator recoveries increased by 77 percent during the period under review.
Implats noted that the increase in labour costs was due to salary rate adjustments while material costs were impacted on by the need for additional material use in both production and support as a result of poor ground conditions experienced north of the Blore shaft.
