For those who have maxed out their general mining skill, advanced mining as a skillset is now available.

It requires an enhanced mining laser, which is available in the Pyramid for sale, as well as the initial starter access card, which is currently available from Professor Humbert (page/assist me if you need one).

The rocks/fossils for this skillset can only be found in certain newer caves, so you may need to do some trekking to get there.
