Exactly what I was going to saySilver laced rooster over silver laced hens will produce 100% pure silver laced hens. And 100% silver/gold laced cockerels.
Silver/gold is sex linked. Females have to be one or the other and they get their gene from their father.
Males can be either or or one gene of each. That's what yours will be. They'll get a silver gene from dad and a gold gene from mom.
They will look silver lace but with a little age the silver will get a yellowish tint from the gold trying to bleed through.
Those cockerels can produce either silver or gold pullets when bred to either silver or gold females.
