HARMONY Gold Mining Company posted a dip in its cash operating profit to R100,4-million for the last quarter of 1998, compared to R104,3-million in the previous three-month period, the company announced on Monday. Net earnings fell dramatically to R38,8-million in the last quarter from R78,2-million in the third quarter, largely as a result of R30-million in retrenchment costs incurred at the Evander and East Rand operations. Harmony said, however, that it is on track to deliver in excess of a million ounces for the financial year, and it is estimated it will reach this target by April.
