The miner said it anticipated its headline earnings per share (HEPS) - the main profit measure in South Africa - for the year until June 30 to stand between 14.8 cents and 16.8 cents, representing an increase of 107.4% to 108.4%.
In a stock exchange statement, the company said it expected to report a record operating profit of 2.4 billion rand ($156.47 million), which it attributed to efforts to contain costs and a higher basket price.
The group had also achieved record production from its own operations, up 7.4% on 2018, while sales volumes increased by 23.3%, it added.
Normalised headline earnings, which in Northam's case are adjusted for the impact of a black economic empowerment transaction, were expected to rise by over 220% to 1.3 billion rand, it said.
