Minto, a tough and experienced 38-year-old heavyweight from Pennsylvania, was similarly relaxed about the arrangement.
"We're not trying to intimidate each other, it's business. As he said, once the bell rings, that's when the action starts.
"We've got a lot in common, both being family men ... we're just trying to be professional about it."
Cameron's manager Ken Reinsfield added: "This fight doesn't need talking up. Both these guys are professionals, they don't need to talk trash to each other. This fight doesn't need to be hyped ... this will be a real scrap."
This is an important fight for Cameron, his first for 12 months since his disappointing defeat to Australian Danny Green as a cruiserweight. Victory would re-establish him in the heavyweight ranks; defeat would leave his career in limbo.
Cameron said there were no mental issues to contend with in terms of his inactivity, but conceded he has come a long way since beginning sparring about eight weeks ago.
"The first two weeks were really rusty for me, I took punches I shouldn't have taken, but once I got the rust out I started to find my groove again."
In terms of his future, he said: "I need to take care of Minto first, if I don't it's a big grinding halt to my career. Beating someone like Minto, he's certainly a well-known name in the professional world ... he's a good name to have on your record. My goal is to get another shot at a world title."
Minto, who said he considered himself a "spoiler", is being trained in New Zealand by Kevin Barry, who underlined his new charge's awkwardness, saying it could create difficulties for the 36-year-old Cameron.
