Nov 7 (Reuters) - Canada's Barrick Gold ( GOLD ) missed

Wall Street estimates for third-quarter profit on Thursday,

weighed down by lower production at its mines.

Barrick's third-quarter gold output missed estimates in

October, weighed by a fall in output at its Carlin and Cortez

mines in Nevada.

All-in sustaining costs (AISC) for gold, an industry

metric reflecting total expenses, rose to $1,507 per ounce in

the quarter, from $1,255 per ounce last year.

On an adjusted basis, the world's second-largest gold miner

posted a profit of 30 cents per share in the quarter ended Sept.

30, compared to an estimate of 31 cents per share, according to

data compiled by LSEG.
