South Africa's Harmony Gold said on Tuesday that the strike in the sector had cost it about 500 kg in lost output.

The company also said in a statement that the deal it reached with the unions would include a profit share scheme on a quarterly basis that would be based on one percent of operating profits minus capital expenditure in its South African assets.

The strike against Harmony and its rivals AngloGold Ashanti and Gold Fields began on Thursday and ended on Tuesday when a wage deal was clinched with the unions.
