The gold miner produced 1.228 million ounces in the year ended June 30, beating its 1.18Moz guidance, making the 2018 financial year the third consecutive year the miner met or exceeded its full-year guidance.

Gold output from its South African operations rose 14%, with a 10% contribution from Moab Khotsong, which produced 105,900oz in the four months it had been included in Harmony' portfolio.

The company announced in October its acquisition of Moab Khotsong from AngloGold Ashanti for US$300 million in cash.

Underground recovered grade rose for the sixth consecutive year, increasing 8% to 5.48g/t.

Harmony expects all-in sustaining costs to be below the R520,000 (US$38,424) per kilogram (R14,742 per ounce) guidance.

The company plans to release its full operational and financial results on August 21.

Harmony said it had fully repaid the US$200 million bridge facility raised for Moab Khotsong using available cash resources and the proceeds received from a recent share placement.

The company's shares were up 2.27% Monday to R21.63 per share.
