* Gold output -14.4 pct yr/yr in October
* Non-gold output up 6.5 pct yr/yr in October
* Total mining output up 3.5 pct yr/yr in October
JOHANNESBURG, Dec 9 (Reuters) - South African gold output fell 14.4 percent in volume terms, while overall mineral production was up 3.5 percent in October compared with the same month in the previous year, official data showed on Tuesday.
Production of non-gold minerals rose 6.5 percent, Statistics South Africa said on its Web site www.statssa.gov.za
South African gold output has fallen since state-owned power utility Eskom [ESCJ.UL] suffered a near collapse in the electricity grid in January.
Eskom has since limited supply to around 90 to 95 percent power to mines in the country, the world’s biggest source of platinum and the second-ranked gold producer. (Reporting by Agnieszka Flak)
