Location

The Blast Mine is located in the northern section of Lovakengj. Blast mining is a minigame which grants Mining and Firemaking experience. Participating in the minigame requires 43 Mining and 100% Lovakengj favour.

Blast mining requires dynamite, which is made by combining volcanic sulphur, juniper charcoal, saltpetre, and a pot, then adding a ball of wool to the resulting dynamite pot. Players use it to blast chunks of valuable ores from within hard rock.

Gameplay[edit | edit source]

The dynamite explodes, blasting rock out of the cavity.

Players must first excavate hard rock using a chisel, then use a pot of dynamite on the resulting cavity. Then, they must light the dynamite with a tinderbox and run at least three squares away from it, or take about 15 damage.

Once the dynamite explodes, players should collect the blasted ore from the ground and deposit it into an ore sack near a working operator. Players have one minute to deposit the blasted ore before it disintegrates, so it is important to be quick. When there are 450 of any single type of ore in the sack, it will become full and the player will need to collect it; the nearby operator will notify them of this. Players can talk to the brown-haired operator on the east side of the machine to collect the ore they mined in noted form, along with Mining experience according to the ores obtained.

Excavating the hard rock earns 20 Mining experience, and lighting the dynamite earns 50 Firemaking experience. Additional Mining experience is awarded along with the cleaned ores.

The Blast Mine is unique in that it enables players to obtain ores as if their Mining level were 10 levels higher. For example, a player with 75 Mining can obtain runite ore here. Boosts work in obtaining ores as well, but it must be active before the blasted ore appears. The experience gained per hour varies depending on Mining level and overall efficiency.

Assuming 330 dynamite used per hour, at level 70, players can expect approximately 50,000 Mining experience and 310,000 coins per hour. This scales up to 80,000 and 800,000 respectively at level 99, with the profit increasing significantly at level 75 with runite ore becoming available. In addition, Firemaking experience is gained at 16,500 per hour, which does not scale.

Including the excavation, each dynamite is worth approximately 180 experience at 75 Mining and 240 experience at 99.

Unlike level boosts, the prospector kit affects the experience received while collecting the washed ore. It is not required to wear it while blasting ore and depositing blasted ore to obtain the bonus experience.

Strategy[edit | edit source]

The north-western corner of the Blast Mine; rocks numbered for reference

To do Blast Mining efficiently, it is important to:

  • Minimise the time wasted waiting for dynamite to explode.
  • Minimise the time spent running to and from the deposit sack.
  • Minimise the amount of damage taken.

These are much easier if a consistent strategy is used. There are multiple patterns that may be used, with little variation.

Only a chisel and tinderbox are required for the activity. A pickaxe is not used, though the special attack of a dragon pickaxe or higher as well as celestial ring slightly increase experience and profit. Graceful outfit is highly recommended, and some run energy restoration (such as stamina potions) is useful for some patterns as they slowly drain run energy.

One efficient method is using the north-west corner, depositing six blasted ore with each cycle. This leads up to 336 dynamite used per hour.

Using the image as reference:

  1. Excavate, place and light dynamite on rock 1
  2. Excavate, place and light dynamite on rock 2
  3. Excavate and place dynamite on rocks 3 and 4, then light them
  4. Excavate and place dynamite on rocks 5 and 6, then light them
  5. Pick up blasted ores 2, 3, 4, 5, 6 and 1, deposit them in the sack by the operator, and repeat (grabbing more dynamite from the bank chest as needed)

When done correctly, no damage is taken and there is room for error without the ore disintegrating.

Changes[edit | edit source]

Date Changes

(update | poll)

It is now possible to place Dynamite into rock cavities at the Blast Mine via a left-click option, rather than having to use Dynamite on a cavity.

A tile of stray blocking in the Blast mine has been removed.

Trivia[edit | edit source]

  • If the player speaks to the operator about the machine, they will state that it is used to quickly clean the blasted ores, and that the design is a secret, with those who try to copy it would "never get it quite right" and that "their machine would break down all the time". This is a reference to the fact that the struts on Prospector Percy's water wheel in the Motherlode Mine often break, while the blast mine's machine never breaks.
