If you are interested in making money, just bank most of your ores and sell them for profit, or use them for smithing, crafting and runecrafting skills.
Farmer100 reminds you should know about pickaxe at first. You can use pickaxe as a weapon to helps you get ores. A player’s mining level determines the type of pickaxe you can mine with. The better pickaxes you use, the higher level ores you can mine, such as Asamantite, Mithril and even Runite. Pickaxes can be bought from Nurmof in the Dwarven mines, Bob in Lumbridge and the Grand Exchange.
Mines are labeled with a grey pickaxe on the map and there are some special mining areas, such as shooting star, Arainian mine and Living Rock Caverns. Personally, I like Living Rock Caverns best, as it has rich coal rocks and gold rocks, which can be mined for multiple amounts of coal and gold. You can also gain a lot of experience and good amounts of money with the nearby deposit box. However, you need certain levels with your cheap runescape accounts to mine them, the coal is 77mining and the gold is 80 mining.
For me, I am now at level 42, in order to make more money instead of leveling up only, I prefer to mine gold ore. It is valuable and always in demand, it is also can be used to make jewellery or smelted into bars for smithing experience. In this case, crafting guild is a good choice for you to get gold ore efficiently. Unless you hit level 80, the Living Rock Caverns will make you profitable. To save your energy and time, remember that farmer100 has runescape accounts for sale.
To mine ores, you only need to left-click once on any rock which contains ores. The color of a rock’s vein is similar to the ores’ color, that is to say, a black vein will yield coal ore, a dark blue vein will yield mithril ore. Right click and select prospect, then you could learn which ore the rock contained. If you are a seasoned player, it is better to recognize the color of the rock instead of prospecting. After changing color, the rock will finally respawn another ore, which you can continue to mine. The more people in the world, the less time it takes to respawn.
Hope this helps you.
