FACTBOX-Chile copper mines, oil refineries at risk from quake

  (Adds comments from mining minister, list of smelters)

 SANTIAGO, Feb 27 (Reuters) - Chile, the world's biggest copper producer,
was rocked by a huge magnitude-8.8 earthquake on Saturday, putting at risk
operations at several of the country's mid-sized mines near the capital and oil
refineries, but sparing the massive deposits in the north.

 The quake affected the 116,000 barrel pre day (bpd) Bio Bio oil refinery
run by state energy firm ENAP, the country's largest, said Mining Minister
Santiago Gonzalez. Bio Bio is located just north of the city of Concepcion,
near the epicentre. [ID:nN27202760]

 ENAP said the quake had also affected its roughly 100,000 bpd Aconcagua
refinery near the capital, and that it would need to increase diesel imports to
meet demand. It said it had sufficient gasoline stocks to last two weeks and
diesel stocks for 10 days. [ID:nN27176503]

 The U.S. Geological Survey said the earthquake struck 56 miles (90 km)
northeast of Concepcion -- which is south of Santiago -- at a depth of 22 miles
(35 km) at 3:34 a.m. (0634 GMT).

 As of 1800 GMT, operations at mines producing over 1 million tonnes a year
-- near one-fifth of the country's total 5.4 million tonnes last year -- had
been suspended by the quake, but they appeared undamaged.

 State-run Codelco said all of its operations were unaffected except for its
El Teniente and Andina mines, which were suspended because of electricity cuts
after the quake but were otherwise undamaged. Garcia it could take two days for
the mines to resume production.

 Freeport McMoRan Copper & Gold Inc (FCX.N) said the quake did not damage
its two mines in the country, but it is facing a power outage at its Candelaria
mine, which will result in a temporary shutdown. [ID:nWEN0976]

 Smaller miners reported little impact. Barrick Gold Corp (ABX.TO) and
Breakwater (BWR.TO) said its mines had not been affected. Teck Resources Ltd
(TCKb.TO) said the quake had not impacted its Andacollo and Quebrada mines,
though they could still be hit by power supply restrictions.

 Here are some facts on key mines in Chile's south-central
region:

 * Anglo-American's (AAL.L) Los Bronces and El Soldado mines
are the closest to the earthquake epicenter. Together they produce around
280,000 tonnes of copper annually. The company is moving ahead with plans to
expand its 238,400 tonnes of copper-per-year Los Bronces, one of the world's
biggest copper mines.

 * Codelco's El Teniente had an output of 404,000 tonnes in 2009. That
marked the end of four consecutive years of dwindling output as lower grades at
aging mines and labor strikes hit output.
