Stone
Stone is the most common ore. It gives nothing when mined.

Coal

Diamond
Diamonds are the second most common ore (stone doesn't count) in Oof Mines. They give about 1000 Money when mined. Its appearance is a cyan version of stone.

Unlike the last 2 ores, this ore has a unique sound when mined. the sound is the guy screaming when he beat a hard gd level (https://www.youtube.com/watch?v=TYU-G-MQ3dY)

Ruby
Rubies are the third most common ore (stone still doesn't count) in Oof Mines. They give like 1500 Money when mined. Its appearance is a red version of stone.

It shares the same mining sound as Diamond.

It plays a loud OOF sound when mined.

Tips

 * Rare ores are mostly around corners and lava.
 * Drills cannot collect ores and give the Money to the driver. If you see an ore, then stand up from your drill.
