Future Battery Minerals (ASX:FBM) said Rocktivity Nepean paid the final deferred consideration of AU$773,656 under the tenement sale agreement between its subsidiary Eastern Coolgardie Goldfields, Rocktivity, and Rocktivity Mining, according to a Tuesday filing with the Australian Securities Exchange.

Rocktivity will no longer make any cash payments under the agreement, except for a 1% net smelter royalty granted to Eastern Coolgardie on all minerals and metals produced and sold on the Nepean nickel project tenements and an additional $500,000 payment, subject to certain milestones, the filing said.
