Silver and gold biomes

Anyone have suggestions about how to give me sweet sweet gold and silver?
I shall call the planet the Ives.

I wish I knew which biome gave me the 8.4% I rolled for my latest sov, but I was actually looking to push sapphire

Awww…No luck with the sapphire :(?

It didn’t turn out badly at all, just not a showstopper thats worth paying for
