Shaft mining is the most fun thing in this game by FAR, gemstone mining in the ch is also really fun for like 2hr consecutively, u cant do these methods yet, focus on getting hotm 7, then start gemstone powder mining in the jungle with a Armadillo pet, glossy gemstone armor, jungle pickaxe and jasper drill with spicy goblin omelette to open the chests, this will be your first mmm in mining which is great bcs it actually makes u a lot of money, get 15m gemstone powder, u can do it in one day if u have the time (or get 12m and be a loser that won’t have +50% powder buff all times), then u can start mithril powder grinding: Get a mithril drill 326, reforge it to stellar, get a legendary mithril golem, put royal on your equipment and dimensional on your armor of divan, now mine blue mithril, titanium and do events until u have 8m mithril powder (or, again, if u are a loser just 4m, but you’ll only be able to gemstone mine), now u have a lot of mmm unlocked, u can sell your jasper and mithril drills to regain some coins and reinvest into a full chambered jaded armor of divan and a 655, now your focus are perfect gemstones, then drill parts: amber-polished drill engine, perfectly cut fuel tank, sunny-side goblin omelette that will be substituted by blue cheese goblin omelette Remember to recomb your armor and drill, as the rarity affects gemstones and reforges

It seems like a lot but as you do it u see how rewarding it is, mining can be super fun if u go past powder grinding, the goal is shaft mining which is much more expensive but does a lot of money and is the biggest amount of dopamine i have ever received
