The best you could do really with bronze is base close to a copper deposit or several ones. What i do is get all the copper needed to make the forge, forge and workbench upgrades, a bronze axe, 5 mead barrels (because it fits perfectly on the upper floor on the back of my room and you get exactly 3 stacks of the mead you prepare every time) and bronze for a Karve. Then i move on to iron.
