I found that the most efficient way to work this house is to have a rune on the porch to the cave entrance and have two archer bots in the porch back doorway behind a table wall and a couple of stools to form a trap at the porch door entrance. Grab a golem or two from the cave and run onto the porch and recall back to the cave after the golems have been trapped. By the time you bring the next golem to the house the first one(s) should be dead. All of the ore just falls onto the porch and you can smelt it all at the end of your session. Jonah and Ringo were my archers, so yeah... it worked well as the golem leaderboard below shows
