Robin Hood - Sherwood Builders

Believe I was awarded a pickaxe as I had one after completing the Tuck tutorial - I didn’t craft one. I found clay deposits along the creek west of the starting village. They are orange and almost waist high stand-alone boulders. Use the pickaxe to completely mine the clay and this will unlock. One deposit takes a few tries - a few small pieces are in top of the boulder then more picking at the large remaining boulder piece.
