Nov 18 (Reuters) - Canadian miner Orla Mining ( ORLA )

said on Monday it would buy the Musselwhite Gold Mine in Ontario

from Newmont ( NEM ) in a $850 million all-cash deal, part of

which is contingent on gold prices.

Orla said the deal will be funded through a combination of

cash, existing undrawn debt capacity, new indebtedness, a gold

pre-pay facility and convertible bonds led by its existing

cornerstone investors.

The company said the deal would help more than double its

gold production to over 300,000 ounces.
