Rubium deposits are rocks found in the Charred Dungeon that can be mined at level 68 Mining to obtain rubium geodes and between 10-100 Mining XP. The geodes can be broken open with a hammer and a chisel to obtain rubium splinters, the quantity of which scales with Mining level. The geodes are not stackable, but the splinters are, so by breaking the geodes players can remain in the mine indefinitely without banking.
Only one of the two deposits is active at a time; the moment one depletes, the other replenishes. Once a player starts mining a rock, it lasts between 4 and 5 minutes, after which the next geode gathered will cause it to deplete.
The resource-duplicating effects of Varrock armour 3, Mining cape, and celestial rings/signets can all trigger when mining a deposit.
To access the deposits, players must moor at Charred Island, requiring level 60 Sailing, and permanently attach a rope to the dungeon's entrance. A rope spawns on a crate just south of the dungeon entrance. The route through the dungeon passes through a multicombat area with aggressive red and black dragons to reach the mine with rubium rocks and deposits.
Locations
Mining info
The deposits produce one rubium geodes on every successful mining attempt, though more can be gained using special equipment.
When a geode is received, a random amount of Mining experience is selected from the table below. Each value is equally likely.
Pre-roll
The mining gem drop table has a 1/256 chance to roll on every mining attempt;[1] if the player is wearing a charged amulet of glory, amulet of glory (t), or amulet of eternal glory, the probability increases to 1/64.2.[2][3] If the table successfully rolls, the player may receive an uncut gem or nothing, and in either case can not receive an ore.[4] This neither depletes the rock nor grants Mining experience. The rates shown are for every mining attempt.

Equipment
Varrock armour 2 gives a 10% chance to receive an extra geode.
Celestial rings and signets provide an invisible +4 boost to Mining level, regardless of charges. When charged with stardust, they also give a 10% chance to receive an extra geode.
Prospector kit boosts Mining experience by 2.5%.
Amulet of glory increases the chance of obtaining gems when charged.
Mining capes give a 5% chance to receive an extra geode.- Varrock armour, celestial rings, and Mining capes roll independently; multiple bonus resources can be given.
