Drake nests that spawn eggs have a nearby vein quite often.

I was in a mountain with both obsidian and a drake nest, no silver, even tried re-equipping the wishbone lol. Unlucky I guess.

obsidian and drake nests can be below the silver line.. stone golems are 99% sure.
The only time I found a stone golem without silver was a one peak mountain just high enough for the golem but probably not even room for the silver.

But that is rare. Stone golem and above is pretty much a sure thing.
