Mining Quarry

As of this writing, December 9th 2019, for the server I'm on...
The HQM Quarry consumes 4x Low Grade Fuel to produce 2x High Quality Metal Ore. This is the smallest amount of Low Grade Fuel you can use to get anything.
Each Low Grade Fuel takes about 10 seconds to consume (rough timing), so you can then derive how long it will take to consume the Low Grade Fuel you have, and how much you will get out of it.
I recommend that you stack your Low Grade Fuel in numbers divisible by 4, so that you don't waste Low Grade Fuel only partly mining.
For example, a 248 stack of Low Grade Fuel will produce 124 High Quality Metal, and take ( 248 x 10 / 60 ) 41.333 minutes to consume and produce.
Generally, a time costly endeavour, but an option if you have a glut of Low Grade Fuel and can't find any other sources of High Quality Metal Ore.

You cant craft Mining Quarry anymore. So i dont know why are Survey charges still ingame

Basically useless unless you are really low on HQM. May be useful for a big clan, but don't farm sulphur with it.

The current output information is outdated!
