I take no credit for the farming glitch below just wanted to share it. It says Ch. 8 but I missed it and was able to go back during Ch. 9 as the side quest will take you to the room. You can literally stand outside the door, open it, back up, let it close and then open it again. I did it about 20 times and then would enter the room, rinse and repeat.
After 40 mins I had the following:
Tungsten: 423
Semiconductor: 1,311
Scrap Metal: 5,071
Somatic Gel: 1,694
Transoucer: 872
I had just upgraded my suit right before doing this so I was able to farm quite a bit of resources.
