 · Hello I'm new to PM recovery etc. I'm trying to set up an indoor space in my detached garagelandfill. I tried one small experiment outside before but when I realized the gold quantity I got looked like Sreetips (YouTube and I believe Kadriver on here) dirty filter papers I decided to accumulate more to process and set up a indoor spot.
