I reckon it's got to do with the restructuring of the HGO gold royalty of $150/oz.

This was from the West Australian:

UPDATE 3pm: Gold miner Metals X has paid almost $1 million in royalties to ASX-listed Carnegie Wave Energy over its Higginsville operations, 152km south of Kalgoorlie-Boulder.

Carnegie today said it had received a payment of $950,115 relating to all mining activities up to December 31.

Metals X secured what many considered the gold bargain of 2013 when it acquired the Higginsville and South Kalgoorlie operations from Alacer Gold for $40 million.

But it inherited a $150 an ounce royalty at the Trident underground mine at Higginsville, which Metals X managing director Peter Cook has called "crippling" to the point it places the mine's future in doubt.
