"The Symmetrium mine tracks its single ore and continuously upgrades it over time. It's azure flame protects the ore from being burnt. Ore is replaced instantly when destroyed."


The Symmetrium Mine is a Reborn-tier dropper. It was first unveiled on Berezaa's Twitter and his old website. The Symmetrium Mine's ores can pass through upgraders that inflicts fire onto ores without being put on fire. However, this blue flame can be removed by the Tesla Resetter, Wild Spore, and Freon upgraders.

Symmetrium ores can only be self-upgraded if the mine they came from exists on the player's baseplate. Symmetrium can be used to replace the 30-second rebirth method that Berezaa patched by attaching Symmetrium Mine to a Cell Particalizer which makes more money than a Yunium Mine.


  • The Symmetrium Mine was released in the same update as the Morning Star with the idea that players would use the mine in Morning Star loops without having to worry about ores being put out.
  • The name "Symmetrium" might be named after a character name Symmetra from the 2016 FPS Overwatch. Berezaa is an avid Overwatch player, who often plays competitive mode (Overwatch is not ROBLOX appropriate).
  • This is the 6th dropper in Miner's Haven to have a special effect. The other droppers are 'Ol Faithful, Noobite Mine , Santa's Workshop , Wubium Mine, Scorpium Mine, and Autumn Breeze.
  • According to Berezaa's Twitch, this item would have replaced Atomium as the go-to mine for high-life setups.
  • Although Symmetrium Mine won't drop another ore until the original ore has been destroyed, Symmetrium ore can be cloned by Ore Replicator althought the clone doesn't self upgrade.
  • Has an Evolved Reborn upgrade called the "Symmetryte Mine." It can be obtained by performing a rebirth with at least 8 Symmetrium mines placed on your base
  • The Symmetrium mine was nerfed from self-upgrading 600 (taking 10 minutes) times to 300 times (taking 300 seconds). In May 2017, ores from the Symcorpium Mine can upgrade themselves 600 times.
  • Upgraders that remove fire from ores such as Wild Spore, Freon-Blast Upgrader, and Tesla Resetter will remove the fireproof effect but not the self upgrading effect. The upgrade effect is linked from the ore to the mine it came from, so as long as the mine exists on the baseplate, the ore will receive its constant upgrade.
  • The Symmetrium mine used to be the highest value mine you can use on Cell Furnaces until the Dragonglass Mine was released on 11/13/2016.
  • The Azure Refiner destroys the ore if the fireproof effect is not treated with an extinguishing device.
  • If the ore still has the blue flames, it can not be accepted by the Sakura Garden. To solve this, simply put a Freon Blaster or Wild Spore before Sakura Garden so it can accept it. (This also works for the Azure Refiner as well)
  • The spout is long enough that it can reach to blocked sides with a 1 unit width.
  • The Symmetrium ores that still have their flame are classified as "hot" and receive a x2 multiplier from Scorching Heat.
    • Ores that had their flame removed will be considered "warm" and get a x4 multiplier instead.
  • This is on the "Reborn" Achievement, showing many of this placed down.
  • Its description has a typo, showing 'it's' instead of 'its'
  • This mine will not work with the Candy Bag unless the Candy Bag has been placed first.
  • There is a panel on the bottom of the mine with a smashed screen and a script code.
  • The screen on the front of the Symmetrium Mine features a lua script which contains the following:
function Weld(x,y) 
local W ="Weld")
W.Part0 = x
W.Part1 = y
W.C0 = x.CFrame:inverse()*
W.C1 = y.CFrame:inverse()*
W.Parent = x
function Get(A) 
if = A.className == "Part" then 
Weld(script.Parent.Handle, A)
A.Anchored = false
local C = A:GetChildren()
for i = 1, #C do
function Finale()
  • As of 12/26/17, Symmetrium Mine doesn't drop ores when directly placed on Dreamer's Anguish.
