I guess I will be the bearer of bad news when it comes to the brown IBM boards. This is just about the gold overlay on the connector pins. I have read all the post on the forum pertaining to them. I happen to come across some awhile back and so I started doing some research. I decided to have an assay done so I would know if they are worth looking for and buy for refining.
I had a couple of boards that had been covered with water and mud and I was able to pull just the pad off of the connector. I called a guy about having an assay done and sent him one gram of the pads that I had pulled. It took 155 pads to make 1 gram.
I sent the pad only and not the connector. The pads are pressure bonded to the connector. The connectors had corroded enough I was able to pop the pad off the connector. On the back side of the pad you could see were the pad had been pressure bonded to the connector.
So I did some math and I have just over a gram of gold in my 6000 gold connector pads on my boards.
according to the essay from 1 gram of pads there is 30 milligrams of gold in 155 pads. That's about 6 and a half clips to get a gram of pads. Each clip has 24 pins per clip.
So to get 1 troy ounce of gold from the connector pins on the brown IBM board you would need roughly 6695 clips.
That would be 160,680 connector pins
I pulled the whole connector with the pad attached off a board and it takes 17 whole connectors to make a gram.
1 ounce of pins = 481 pins that equals roughly 20 clips and that's about 1/10 of a gram of gold per ounce of pins.
I spent $60.00 for the assay and I wont get that much gold out of my pins but if I can help members here on the forum from spending money on those boards looking at getting a return from the connector pins on those boards it was worth it to me. I would dismiss all other info posted about those connector pins.
I know Lou and goldsilverpro say to get 2 assays done. I am not going to follow their advice on that. I do have 1 more gram of just the pads. If a trusted member would like them to have an assay done I will give them up freely.
Pictures added if they are to big will a mod please resize them. Tried to post them from photobucket but don't know how.
Sorry about the long rambling post.
