I couldn't find this anywhere else, so I decided to put it in here. It's a great way of mining gold fast.
Requirements:
Must have at least started Fairy tale part 2 and have use of the fairy rings
Must have started Holy grail quest.
Use Lost City Bank. Bring your pickaxe and drammen- or lunar staff.
Use Fairy ring transport with code BJR. Go toward houses and pick up magic whistle.
Blow whistle, and you are in Brimhaven gold horseshoe mine.
Mind ur gold, go stand under hut and blow ur whistle again. Cross bridge and use fairy ring back to Lost city.
You can either use fairy ring, or you house if you move it to Brimhaven.
Good luck

Edit: You don't need glory ammi to bank your stuff. You just walk under the house and blow the whistle, then use fairy ring back to Lost City.
