These are located in Al-kharid, Legends Guild, Piscatoris, Verdant Valley and Mount Karuulm. Without tick manipulation, players can expect 45k - 55k Exp per hour.
You’ll want to power mine iron ores all the way until 75 for the fastest mining experience per hour. Use the 3-rock locations only as this is the most efficient setup for the maximum experience per hour. From mining level 60 you will start to insta-mine iron ore giving you a huge experience boost.
The three most common types of surface mining are open-pit mining, strip mining, and quarrying. See also mining and coal Surface mining, method of extracting minerals near the surface of the Earth.
