|Originium Crude Ore||300|
|Originium Ore||300 ~ 1800|
- The amount of Orundum received will only be shown after the mining operation is completed.
- If the mining operation does not reach an Originium Vein, the next mining operation(s) are more likely to reach it. If the Originium Vein was not reached by the end of the event, then the last mining operation is guaranteed to reach an Originium Vein.
- Unused mining operations do not transfer over to the next day, so they must be used before the daily reset.
