1-15 minde tin ore. Will need around 10 ores to reach level 15 mining.
15-30 mine iron ore, will need around 20-30 ores to reach level 30 mining.
30-55 you will need to mine coal. You will need around 50-60 ores to reach level 55 mining.
55-70 you will need to mine mithril ores. You will need around 180-200 ores to reach level 70.
70-85 you will need to mine adamant ores. I'll get 99 mining soon so pm me in game if you want to know how many ores 70-85 you need to mine.
85-99 mine rune ores. As I said earlier just ask.
You make some profit, but I would suggest using your ores to train smithing skill. I'm 1 smithing but I'll be realising guide soon.
You also get rocks such as uncut diamonds,dragonstones, ect which means you make extra profit. Or you could use stones to train skill crafting. You wont get enough rocks to 99 crafting so yeah.
Thanks for your time reading this, this is my first guide. Hope it helped.
