I always try to kill 2 birds with 1 stone. When you need silver or plan on clearing some frost caves, head to the mountains, fix up a log cabin or keep and plop in a portal. When I go searching for silver, I will take a few deer meat with me, just in case. Dig out the silver when you find it, but don't mine it, use the pit for taming 2 star wolves. Give the silver pits a noticeable icon for your mini map (I use the campfire icon), that way you quickly know where there is a taming pit available once you are chased by a 2 star. Be ready though as 2 star are usually part of a pack of 3 wolves. The key of course is having a shield handy, cause it is not that hard to block/parry back them up into the pit, and hope you see them at range before they see you, so you can take out the non 2 stars.
