​OSRS Volcanic Mine Guide

Nov-25-2020 PST

Underneath the Fossil Island Volcano, there is a large volcanic chamber called the Volcanic Mine. The entrance is located in the north-eastern corner of the volcano, with an NPC named Petrified Pete guarding its entrance. You need to have a Mining level of at least 50, 150 Kudos and five unidentified small fossils from Peter.

Keep in mind that players have to pay 30 numulites (a form of currency on the Fossil Island) to Petrified Pete if they wish to enter the mines again.

Equipment Setup

- A good equipment setup consists of the full prospector kit for the 2.5% extra Mining XP.

Inventory Setup

· 12-16 Monkfish or Better

· A Prayer Potion (Not needed if you have 91+ Prayer and 30+ Prayer bonus)

· A Pickaxe

· Stamina Potion

· Numulite

· Teleport to House Tablets

· Volcanic Mine Teleports


An item called heat-proof vessel is given to whoever enters these mines. The time limit given to a player to organise themselves is 30 seconds, after which the game will start as the volcano rumbles. After the game begins, the players will have exactly 10 minutes to mine and get out, because after that the volcano will erupt and anyone who hasn’t escaped will be killed.


Your first and foremost goal is to mine the large boulders that can be found in the lava channel. These boulders get smaller in size as they’re mined and are carried downstream as you mine it, so you must follow it down the stream and mine it whenever it stops. The smaller the boulder gets the more points are to be gained. Depending on the player count, a boulder will spawn. If the player count is around 10, then the boulder will spawn in the central channel, and if there are more then another boulder will spawn at the western channel. Likewise, if there are more than twenty, then the third one will spawn at the eastern channel.

NPCs called lava beasts start to appear as well, upon entering the lower level. They attack by launching fireballs, and it is recommended that the player keep 'protect from missiles' on to reduce the high damage attacks to 1. To walk around in the lower level where lava is more, one must harden the lava by pouring water on it from the heat-proof vessel that you received when you entered the arena. The vessel can be used up to 35 times per game and around 70 if the player has unlocked the larger capacity with his points. The lava that is hardened has a time limit of melting, which is around 90 seconds and can be indicated by its colour change (orange indicated that it’s about to melt). Falling into the lava will not kill you depending on your hp, but you may take in a massive amount of damage.

While mining the boulder, you may receive other different ores as well, along with normal ore fragments. Different ores being; Calcite, Pyrophosphite, Numulite, and Unidentified Fossils.

As you can see on your right, there are three volcanic gas chambers into the volcano and there are two vents for each of these chambers. One of each set is on the downstream and upstream side of the lava channels, and the pressure from these vents is revealed to all the players inside the game. After every five minutes, the statuses of these chambers shift and are randomised, as well as hidden for players to find again. Gas chambers can also be blocked by large rocks to increase the pressure, or mine the large rock away to decrease it. This should be done because the pressure of each chamber must be kept around 40-60% or else the volcano will start to become unstable and start to shoot out fireballs.


If the mine stability becomes 0%, the volcano will erupt and kill everyone who is inside. During the occurrence, players who haven’t escaped through the rope exit will not receive any reward points or experience.

There is also a good strategy for players who run out of water in their vessels, which is using the gas holes. These holes are scattered throughout the mines and be ‘felt’ to shoot them to the other side of the lava channel. This does cause a little bit of damage but opens up a shortcut for players who are low or run out of water.

If all the players together manage to completely mine the boulder, then it will flow into the vortex of lava, which will grant all the players who are in the lower level with 100 extra points.

In the last 10 minutes of the time, or if the stability of the area becomes low and results in the eruption of the volcano, then it is recommended to start running towards the exit when around 30-40 seconds are remaining or you won’t end up making it, which will result in your character being killed. If the player ends up dead, not to worry because the items can be bought back from Petrified Pete for 150 Numulites.


- Leaving the mine alive and through the rope exit, players will gain participation points depending completely on how they performed in the minigame. The ore fragments that are obtained by you during the game will be given to Petrified Pete automatically, who will grant you with Mining experience and Bonus points in return, and can be spent in Pete’s Ore Shop. For each point earned, Pete will grant you with around 5-5 mining experience and players who die inside will unfortunately not receive any points or bonus experience.

- You can get up to 40,000 Mining experience per hour through volcanic mine at level 50 Mining, and around 85,000 – 95,000 Mining experience if you’re at level 99 Mining.

- Also, the maximum amount of points that a player can have is 2,097,151. Any more than that, a warning message will be shown next to the points.

- The most valuable ore per point is Runite ore, and volcanic ash is also valuable and useful for Ironmen.
