Campbell currently leads the Cappielow scoring charts with nine strikes and, ahead of tomorrow's clash with Livingston, Moore has hailed his young strike star.
He said: "Wee Archie has popped up with a few goals and the rest of the team are chipping in and doing well.
"He has done well for us and he is relishing it up there. We are playing the sort of balls he likes and he is putting his chances away when he is getting them.
"And long may that continue because we only have him and Peter [Weatherson] at the moment, with Martin [Hardie] only making cameo appearances so far.
"Archie is playing with confidence just now and we are playing a way that he likes.
"He is putting chances away this year, whereas he was maybe snatching at them last year.
"That comes from confidence and he is getting that by scoring goals."
