Russian state uranium miner ARMZ plans an offer to acquire Canada's Khan Resources in a $33 million all-cash deal that would secure access to a large uranium field in Mongolia and boost its drive to expand abroad.

Prime Minister Vladimir Putin this year granted $1.5 billion to state nuclear giant Rosatom, the parent company of ARMZ, to boost the war chest of the world's second-largest uranium miner by resource base as it pursues assets abroad.
