Well here it goes for an nice premium
Items needed:
1 - Y-8 Mining Ship (POB) Outfitted with everything to fly (and shield) and a Y-8/POB Cargo Hold
1- Mining Laser (Best to use one for a Y-8, or the best one you can get)
3 - Tractor Beams
1- Master Pilot (you)
Place the mining laser for pilot operation
Place the tractor beams in the two front (lower) turrets, and one in the top turret (sorry, forget which mubers they are)
Get in the space where the asteroid you want to mine is
Run your overloads (I recommend Weapon Capacitor and Weapon Overloads and maybe Reactor if you need to)
Get in the top turret and press the firebutton to engage Tractor beam... HOLD THE BUTTON DOWN!
KEEP HOLDING THE BUTON and press "L" to leave the turret. You should still hear the tractor beam running as you move around the ship (but may/maynot see the beam out the windows)
Go to the lower/front turrets
Aim and repeat what you did in the top turret (REMEMBER: Hold the fire button down as you exit the turret)
Repeat for the next turret.
**NOTE: There is a possibility that the other turrets (after the first one is done) will not appear to fire at all, or appear to fire something else entirely.. not to worry.. its a glitch.
Now your ready to mine.
Go to the asteroid and open fire. Keep within 200 meters of the large chunk as you fire to break it appart.
This range will allow for the beams to work seperatly and bring in nearly 90% more of the material than you wold in another ship.
Keep in mind that the cargo hold is HUGE and to get to 1% is a LOT of asteroid.
I usually mine EVERY type in space in a single run... taking 1%-2% of each before landing. This is usually plenty to craft with with exception of maybe making chassis.
