The deaths occurred on August 15 at its Thembelani mine, and on September 11 at its Dishaba mine, Amplats said.
It was investigating the deaths.
The lost-time injury frequency rate at managed operations for the year-to-date September 2014 was 0.64 per 20 000 hours worked, 41% lower compared with the same period in 2013.
Total equivalent refined platinum production - equivalent ounces are mined ounces expressed as refined ounces - decreased by 14% to 533 000 ounces, compared to 623 000 ounces in the third quarter of 2013.
The year-to-date ounce production loss as a result of the platinum strike and subsequent ramp-up amounted to 532,000 ounces. The strike accounted for 424 000 ounces and the ramp-up for 108 000 ounces.
Association of Mineworkers and Construction Union members at Amplats, Lonmin [JSE:LON] and Impala Platinum [JSE:IMP] downed tools on January 23, demanding a R12 500 basic monthly salary.
The strike ended on June 24 when they accepted a three-year wage deal that would increase salaries by R1000 in the first and second year and R950 in the third year.
The company said: "Rustenburg, Union and Amandelbult mines successfully returned to normal production during the quarter, however, output was 98 koz (thousand ounces) or 34 percent lower at 192 koz.
"This was as a result of the ramp-up following the conclusion of the strike contributing 92 koz and planned lower production from Rustenburg and Union following the restructuring."
Refined platinum production decreased 31% to 460 000 ounces due to lower mined supply and the build-up in pipeline inventory following the drawdown on inventories during the strike.
Sales volumes declined over the prior year due to a reduction in refined metal produced following the strike.
"Preparations for the sale of Union mine and concentrator have been finalised and the sale process has commenced."
