SANTIAGO, Dec 20 (Reuters) - Chile's state-run copper

giant Codelco produced 125,500 metric tons of the metal in

November, up 18% year-on-year, but still fell behind its target

for the month, an internal document obtained by Reuters showed

Friday.

The miner's output was 3% lower than expected, according to

the document titled "Preliminary Corporate Results" and dated in

December. The only divisions to meet their target were the

massive El Teniente and the smaller Radomiro Tomic.

Codelco did not immediately respond to a request for

comment.

The copper giant, which is the world's biggest producer of

the red metal, has been aiming to quicken production to meet its

2024 target after levels in the last two years hit a

quarter-century low.

After November's performance, Codelco will still need to

produce more than 161,000 tons of copper in December to reach

the low-end of its target, which the company earlier this year

put between 1.325 million to 1.352 million tons.

Senior company sources previously told Reuters that

Codelco expects to end the year at 1.331 million tons, which

would be 0.5% above last year's output.

November production was hurt by delays at the Rajo Inca

project at the Salvador mine, according to the document. It also

showed lower recovery and processing at the Andina, Chuquicamata

and Gabriela Mistral units and lower ore grades at Ministro

Hales.

Smelting and cathode production were also below

Codelco's target in November, according to the document.
