Lam is back in the country - for the first time since he left Wigan in 2004 - on a fact-finding trip ahead of the end-of-season World Cup, checking out training facilities and the form of the six PNG players based in England.
"I think we'll bring a squad of 22 and that may include 12 locals, five or six of which are really talented." said Lam, who will be taking part in his fourth World Cup, his second as head coach. "I think once the Super League see them, they'll be snapped up straight away. Three of them are pretty special, as good as any in the world."
He added: "Once the Super League clubs see these young kids, they'll be all over them. They'll be in the shop window and they'll be cheap."
Lam watched Wakefield hooker Paul Aiton in action against Hull KR on Sunday and is catching up on the progress of Huddersfield second rower Jason Chan as well as Championship players Menzie Yere (Sheffield), Rodney Pore and Jessie Joe Parker (both Whitehaven) and Makali Aizue (Dewsbury).
"Everyone is under consideration," said Lam, who will also be able to call on several stars from the NRL.
The youngsters will be aiming to follow in the footsteps of Stanley Gene, who arrived with the 1995 Kumuls and stayed in England after the World Cup to enjoy a long and productive career with Hull KR, Hull FC, Huddersfield and Bradford.
Gene is now on the backroom staff at Craven Park, where PNG will open their campaign with a group B match against France on Sunday, October 27.
Samoa and holders New Zealand are the other teams in a tough-looking group, with three to qualify for the quarter-finals.
