Both are among 24 local government areas allocated a base amount of $1 million in the program's eighth round, with applications now open to determine which areas and projects will be granted the lion's share of the remaining $51 million.

Deputy premier John Barilaro announced the new round of funding on Monday, explaining necessity will be the biggest factor in determining additional funding for the eligible communities.

"You've heard me say there is more to come and here it is, another $75 million to fund projects and programs that will ensure our mining communities remain strong for generations to come," Mr Barilaro said.

"We know that the mining industry can put extra pressure on local infrastructure in regional towns and this fund is about giving back to these mining communities that contribute so much to the NSW economy.

"It's absolutely crucial that we continue to support regional mining towns that supply our state with the resources we need.

"Round eight of the ... fund will build on the success of the previous round, which provided $50 million for 84 projects that helped create new jobs and stimulated local economies through infrastructure and program delivery."

Since its inception in 2012, the Resources for Regions program has delivered 149 projects worth $345 million to the state's mining communities, and the NSW Minerals Council welcomed Monday's announcement of additional funding.

"It's good to see the NSW Government will continue to drive this important investment in mining regions," NSW Minerals Council chief executive officer Stephen Galilee said.

"The $75 million of additional funding ... is a significant increase on the previous round and will be welcomed by NSW mining communities."

Applications for the eighth round of the program are now open and close on July 12 at 12pm. Program guidelines and eligibility criteria are available on the NSW Government's website.
