UPDATE 1-Chile sees $105 billion mining investment from 2014-2023
(Adds detail on investments, background)
SANTIAGO Aug 25 (Reuters) - Mining investment in Chile, the world's top copper producer, is seen at around $105 billion from this year through to 2023, state copper commission Cochilco said on Monday.
Cochilco said investment likely to be completed over the five-year period 2014-2018 totals around $30 billion, equivalent to that of the five-year 2009-2013 period.
Chile is battling sliding copper prices, rising costs and falling ore grades in its aging deposits.
The period through 2023 includes investment by Codelco, the state-run company that is the country's largest copper operator, of $28 billion in a program of project expansion and new mines, Cochilco said.
Planned investments also feature 14 companies that are looking to implement medium- or large-scale mining projects in Chile for the first time, and nine new mining projects with an estimated investment of $8.9 billion, including seven for copper, Cochilco said.
Chile still produces about a third of the global supply of the base metal, used in construction, and no other country is likely to be able to catch up soon.
