The Lava Flow Mine is one of the most important locations of Keldagrim, being the main source of the dwarven city's power supply. It is run collectively by the Consortium and overseen by Foreman Jaak. The mine was first released along with the quest King of the Dwarves on 4 January 2011. Later, a training area associated with the mine was released on 16 May 2011. It is a place for players to train Mining quickly without gaining ores (though gems may be acquired) and by pleasing the Liquid Gold Nymph, players may attain pieces of the golden mining suit. A Mining level of 65, a Smithing level of 70, and a Strength level of 77 are required to complete the quest and are therefore required to use the mine.

The Lava Flow Mine acts as a geothermal power plant, using Gielinor's thermal energy (the lava) to turn water into steam, which in turn operates the various mechanisms around Keldagrim.

Mining urns, Bonus experience, and clan avatar experience boosts work at the Lava Flow Mine.

Mine info[edit | edit source]

History[edit | edit source]

Located in Keldagrim, the Lava Flow Mine is used as the primary power source for the city. It creates steam, on which many of the city's machines work (similar to the Blast Furnace). It is a vital part of Keldagrim - the Green Gemstone Director calls it the single most important piece of machinery in Keldagrim.

At the start of King of the Dwarves, a cloaked figure blows himself up in the mine, causing a cave-in, which wounds six of the miners. He blows up the secondary boilers only, and black guard troops come to fix them very soon. They leave the miners under the rubble, for the player to mine them out. Though at first it seemed that the guards were not concerned about the trapped miners, it is revealed that if the boilers weren't fixed, they might have exploded, causing further deaths and leaving most of Keldagrim without power for days. After the quest it seems 3 of the 6 miners have died: 2 died immediately, and 1 more died of his wounds later on.

During the quest the Blue Opal Director reveals how the lava flow mine works. The lava comes from the sub-Barendir magma vent. It is siphoned off from this vent and run along channels in the mine. The lava heats water in primary boilers over the channels, and the steam created is channelled into seven secondary boilers in the centre of the mine. From here, the steam is pushed through distribution vents to the various machines around Keldagrim, such as the mine carts and the blast furnace.

Location[edit | edit source]

The Lava Flow Mine is located through an opening on the east wall of Keldagrim. The easiest way to get there is by using the mine cart from the Grand Exchange to travel to East Keldagrim, and then run northeast.

Alternatively, players who have level 99 in at least one skill or are able to wear the quest point cape can tune the Prifddinas Max Guild skilling portal to the Lava Flow Mine. The portal will teleport the player inside the Lava Flow Mine.

Requisites[edit | edit source]

Required[edit | edit source]

Recommended[edit | edit source]

Optional: Ghostspeak amulet, cramulet, or completion of the hard Morytania achievements to speak to the Dwarven ancestor spirit. This is required to understand him and hear his story. These items are not needed to get the reward +10% experience for 10 minutes.

Segment Location Table

Mining[edit | edit source]

The main purpose of the Lava Flow Mine is to mine off crust from one of the four lava channels. Foreman Jaak will say which of the four lava channels needs the most attention, which will also yield the most mining experience per successful cut of the crust. You can check the steam gauges next to each channel segment to see the flow in that segment - the segment with 50% flow gives the most experience.

After a while (anywhere between 4 to 7 minutes), the flow rates change; you will receive a message in your chatbox when this happens. Jaak will know which one yields the most experience again. Unless the world is fairly full, it is advised to talk to Jaak instead of finding the correct flow yourself, because finding it with too few people might take too long. The segments next to the one with 50% flow will have 60% flow, and the next segments 70% flow and so on. This can help in finding the best segment to mine.

When mining the best channel segment, one successful cut yields 100 experience when the exact correct part of the correct flow is mined. Experience gained is proportional to the flow in that segment, as shown in the table below.

Flow rate Experience per mine
50% 100
60% 90
70% 80
80% 70
90% 60
100% 50

Strange rocks can be obtained from mining the crusts.

Finding the blockage[edit | edit source]

When the blockage segment moves, immediately go to Foreman Jaak near the entrance to find the new channel. Once you know this information, go to the steam gauge for either segment 4 or 5 of the new channel and find the percentage. If it isn't 90% (which only one end can be from the centre segments) or 50%, then check the other segment's value and use that as an offset to find the location.

Segment 5 Segment 4 Blockage
90% 80% 1
80% 70% 2
70% 60% 3
60% 50% 4
50% 60% 5
60% 70% 6
70% 80% 7
80% 90% 8

As an alternative to asking Jaak, the correct channel can be found by reading the flow at two central locations in segments 4 or 5: between channels A and B, and between channels C and D. At each location read the two dials, and stop as soon as you find the one with less than 100%. Then read the neighbouring dial to find the direction of the correct segment.

Maximising experience rates[edit | edit source]

To maximise experience rates while in the Lava Flow Mine, you must be mining the segment with 50% flow. This can be quickly identified by firstly looking in segments 4 or 5 of each channel to find the one with below 100% flow, or talking to Foreman Jaak to be told which channel letter is slower, and then moving along it until you find the 50% flow, once here, you should begin mining.

Also, it is recommended to mine in any of the unofficial worlds with a clan to find the 50% segments faster.

At level 80, the maximum experience per hour with only a lava titan, no other boosting equipment/items, and a pickaxe:

Pickaxe XP per hour (no urns) XP per hour (with decorated urns) XP per hour (with decorated urns + urn enhancer)
  • Necronium pickaxe + 4
  • Crystal pickaxe
60000 72000 75000
  • Bane pickaxe
62000 74000 78000
  • Bane pickaxe + 4
  • Imcando pickaxe
68000 80000 85000

The current maximum experience is around 100,000 per hour (200,000 per hour with Bonus experience) at level 99 with a good team and a lava titan.

Distractions[edit | edit source]

There are multiple distractions that can occur while mining the crusts.

Players fixing a broken boiler in the Lava Flow Mine.
  • Boiler breakages - As a result of the chaos dwarf attack, the boilers overheat. Repairing them takes a random Smithing level (70 to 90, boosts may be used) and a hammer (tool belt works), which spawns at the mine entrance. If you fix it you will gain Smithing experience based on the required level. This cannot be assisted. A boiler will break on average about every 1 hour and 10 minutes[source needed], although the time between breakages is random. You will get a red message in your chatbox whenever a boiler breaks.
    • To see how much experience you would get when repairing a boiler, see the calculator below. You can only repair one boiler per hour.
    • This formula is where is the smithing level required.
 template  = :Lava Flow Mine/Boiler calculator/Temp
 form      = CalcForm
 result    = CalcResult
 param     = Smithing|Smithing level (70-90)|70|int|70-90
This text will disappear if the form is loaded properly.
  • TzHaar hero - The TzHaar hero will chase a lava monster along the channels of the mine. Players can stall the lava monster by taunting it. If they can do so for long enough for the TzHaar hero will catch it, everyone inside the mine will be twice as likely to find gems for the next ten minutes. You will get a red message in your chatbox when the bonus comes into effect and also when it ends.
  • Possessed pickaxe - A Dwarven ancestor spirit will take control of a nearby pickaxe. If the pickaxe is defeated, the ancestor will grant a 10% Mining experience bonus for ten minutes to the player who killed it. You will get a red message in your chatbox when the bonus comes into effect and also when it ends. The bonus stacks multiplicatively with a Double XP Live multiplier. Note that killing multiple Possessed pickaxes and speaking to the Dwarven ancestor spirit within 10 minutes of one another will not add an additional 10% bonus but will restart your 10 minutes.
  • Liquid Gold Nymph - The Liquid Gold Nymph appears once you fill your progress bar. She will give a piece of the golden mining suit when talked to. If you already have a full set of the outfit, she will offer you 2,500 Mining experience or the option to gild any single pickaxe you have in your inventory or on the tool belt (not including the inferno adze, crystal pickaxe, dwarven army axe, or sacred clay pickaxe). You will get a message in your chatbox when she appears, and a sound will play. The progress bar (upper, blue bar) fill rate is affected by the stamina bar (lower, yellow bar), the possible progress you do per strike is based on whether the stamina bar is 100%, 1-99%, or 0% full, doing 100%, 90%, or 20% damage respectively. So keeping it from becoming empty by clicking on the mining location again at any time before or after it becomes empty makes this process faster. It IS possible to four tick this by clicking every 2.4 seconds, but as this only increases your damage from 90% to 100%, it’s likely not worth the effort. Each bar takes approximately 10–20 minutes to fill depending on stamina bar maintenance.
  • Lava geyser - (requires completion of Birthright of the Dwarves): Occasionally a lava geyser will appear in one of the lava sections. First, players have to cool it down by using Water or Ice spells. After it has cooled down, it can be mined for a hefty amount of Mining experience. When the cooled down geyser has been mined completely, it will disappear and players will receive an Imcando pickaxe fragment.
    • Note: It is announced in the chatbox when a geyser appears.

Monsters[edit | edit source]

Rewards[edit | edit source]

Golden mining suit[edit | edit source]

In addition to the Mining and Smithing experience obtained by contributing to the mine, the Liquid Gold Nymph will appear when the progress bar is filled and reward players with a piece of the golden mining suit in the following order. Wearing all five pieces gives a 6% boost to experience while Mining (1% set bonus), similar to the effects of the lumberjack clothing set. It is no longer possible for a player to obtain multiple suit pieces. Previous to a recent update, one could drop a piece that they wish to obtain and then talk to the nymph for another then proceed to pick up the piece they dropped after they receive the piece they want from the nymph (The option to drop was replaced with destroy).

*If the player owns any Varrock armour, the mining top will also give the chance of receiving extra ores (up to whatever ore your Varrock armour would normally allow). 

Gilded Pickaxes[edit | edit source]

The Liquid Gold Nymph will also offer to trim the pickaxe in the players inventory or tool belt, if they have acquired the complete golden mining suit. Foreman Jaak can remove the gilding on any of the pickaxes.

The player also has the option to get a 2500 experience reward instead of a gilded pickaxe, by asking if the Liquid golden nymph has nothing other than gold.

Imcando pickaxe[edit | edit source]

The Imcando pickaxe.

During the Lava geyser distraction, the player has the chance to obtain Imcando pickaxe fragments. These fragments can be used to create an Imcando pickaxe. To do this the player will need to bring the following to Thurgo after completing Birthright of the Dwarves:

Trivia[edit | edit source]

  • If you speak with the Dwarven ancestor spirit while wearing the ghostspeak amulet or the cramulet, he will tell you a story about how he used to be the #2 miner in ancient Keldagrim, and he was killed by a lava monster before he was able to compete for the #1 miner spot.
  • Mining from a lava flow or even being within the mine should kill the player due to convection and radiant heat, since the heat from the lava would convect (and be radiated) into the air making the temperature too high for a human to survive; the foreman mentions this and says it's a wonder that it doesn't happen.
  • On 12 January 2012, after The Firemaker's Curse game update, players at the Lava Flow Mine found it impossible to cross the bridges to access other channels. This was later fixed in a system update.
  • Sealed clue scrolls may also be obtained from mining crust.
