Oct 17 (Reuters) - Australia's largest gold miner Newcrest Mining on Tuesday posted an 18.1% sequential fall in quarterly gold production, hurt by maintenance shutdowns during the quarter.

Planned maintenance activities at the miner's Cadia, Telfer, Brucejack and Red Chris projects resulted in a lower throughput during the quarter.

Newcrest, which is currently in the final stages of ratifying a $16.81 billion takeover from Newmont, produced 454,312 ounces (oz) of the precious metal in the three months ended Sept. 30, compared with 556,187 oz in the quarter ended June 30.

The country's largest gold miner said output from its key Cadia mine in New South Wales came in at 122,663 oz, down 19.3% from previous quarter. (Reporting by Nausheen Thusoo and John Biju in Bengaluru; Editing by Shailesh Kuber)
