Saltpetre detail

Saltpetre is obtained using a spade on a saltpetre spawn, in the Hosidius region of Zeah, south of the main bank. It spawns at one of five possible locations, moving when it is depleted. It can also be obtained as a reward from the Chambers of Xeric and Wintertodt.

Players with a high Mining level can collect 1500+ saltpetre per hour; however, players with level 1 Mining will only be able to get about 850. This is because when you mine saltpetre, you have a chance of receiving two blocks, and this chance is roughly equivalent to your Mining level out of 100. A higher Agility level, energy potions and weight-reducing clothing are also advantageous.

Saltpetre ingame

A half-depleted saltpetre spawn.

The NPC, Konoo, will follow the saltpetre around, so it's helpful to look for a yellow dot on the minimap when searching for the new spawn. He provides players with a free spade, should you not have one.

Hopping worlds to find the saltpetre location just south of the bank can cut down on banking time.


Saltpetre is used with regular compost to create Sulphurous fertiliser, which can then be used to gain favour with House Hosidius by donating it to the clerk south-west of the bank, at a rate of 0.1% favour per two buckets. This also grants 2 Farming experience per bucket of fertiliser made.

Saltpetre is also an ingredient in making dynamite for Blast Mining, in addition to being used to fertilise vine patches in the Vinery.
