A good place to begin is the goblin caves near here. There are greenstone deposits near the surface. There are of course goblins as well, so be very stealthy, or better yet find a strong sword arm to help you. Ask here at the inn or near the well, I have found willing companions in either place. Once you have the greenstones they are among the easiest to work with.
