The profit rate assumes 550 pay-dirts are excavated per hour by default. Other assumptions include that the player has 99 Mining and is wearing the prospector's outfit and has all upgrades to the mine purchased. For the expected profit rates at lower levels, see the table at the bottom of the guide.

Motherlode Mine, located in the Falador Dwarven Mines, is a somewhat popular Mining training method as it is low effort, can yield good profit and 30,000-60,000 Mining experience per hour.

By mining pay-dirt and cleaning it in the machine located in the centre of the mine, players collect random ores from the sack. Depending on their mining level they can obtain coal, gold (134), mithril (141), adamantite (553), and runite (10,158).

Randomly, players can also receive golden nuggets that can be traded in for a prospector's outfit, which grants a 2.5% XP boost to Mining if the full set is worn.

At 57 Mining, which cannot be boosted, 100 nuggets can be spent to unlock permanent access the upper level which has veins with longer depletion timers. For another 50 nuggets, a chute can be unlocked to deposit pay dirt from the top floor instead of needing to use the ladder. For 200 nuggets the pay-dirt sack can be upgraded to hold 189 ore instead of 108 ore.

A dragon pickaxe or crystal pickaxe are strongly recommended.

Using a charged amulet of glory and a gem bag only slightly raises the overall profit due to how receiving a gem works. However, due to the sack capacities being a multiple of 27, holding a gem bag (or hammer) has no negative effect on rates.

A coal bag can be used to speed up the banking of the ores retrieved from the sack (best used with an upgraded sack).

Upon completing the Elite Falador Achievement Diary, players will have an increased chance of receiving higher ores when cleaning pay-dirt, which will increase profit per hour.
