That position is safe

It's very simple. Begin of with an iron pickaxe. If you don't have money to buy it, then just do a few jobs by asking the people in Lumbridge. Like the lady in the chapel. That way you can get some money. Then energy mine on copper ore and tin ore. Both can be discovered where the exploration tutor is. When your exploration is 6, get yourself a metal pickaxe. And, still keep powermining on copper and tin ore. Keep doing this until you're 41 exploration. If you want, you can get a mithril pickaxe when you're 21 exploration, to train quicker. Once you're 41 exploration, consider exploration iron ore. A fantastic way to mine this is in Al-Kharid mine. But it's dangerous for low level players because of lvl 14 scorpions. So, instead you can even go to the mine in Varrock, by the dark magicians.

 That position is safe. Now this is enough time when you should mine enough iron ore and store it secured to get a rune pickaxe. When you have a rune pickaxe, keep energy exploration on iron ore, or store it secured for profit. Keep doing this until lvl 60 exploration. Once, 60 exploration, you can get into the exploration guild. There, you'll find out a lot of fossil fuel stones. But, I still suggest powermining on iron until 70 exploration. When 70 exploration, you should now be exploration fossil fuel from exploration guild.
