On the way to the Munbury Mountain, I chose to not service the Northcrest guard (to unlock his heart you have to be a submissive bottom to get this interaction).
Once Dulrig started to mine emerine, I walked around the dungeon until the Golems appeared (I didn't use teasing attacks to defeat them), just ate Dulrig out ONCE (I think that interacting with him too much may affect the results of the mining but i might be wrong), and at the end I put 5 emerine crystals of my own.
those are all the steps that I followed, and I used the game log and the wiki for some help. Sorry if my explanation or writing is a bit faulty (。﹏。*)
