* Sees $5 bln revenue over 10 yrs
* Sees capex of $405 mln
March 22 (Reuters) - Centerra Gold said it expects to extend mining and milling operations at its Kumtor project in the Kyrgyz Republic to 2021 and projected a net cash flow of about $1.5 billion in the next 10 years.
The gold miner forecast $5 billion in total gross revenue from January 2011 to 2021 and capital expenditures of $405 million, including the replacement of existing open-pit mining equipment.
The forecast is based on a new life-of-mine plan, which accounts for the mine's open-pit reserves and not production from underground mining, Centerra said in a statement.
Shares of the Toronto-based miner closed at C$16.01 on Tuesday on the Toronto Stock Exchange.
