I went through the entire bag that contained the e-scraps and most of them are CD-ROM drive I guess, but could find the following cards which seem to be audio and graphic cards, which seem to have the fingers you mentioned in your post here. Please advise

I also messed around with the copper coils in this board, and It weighed around 2.75 grams what seems to be pure copper from on that board. So by doing the math here;
150 gram board has 2.75 grams of pure copper coil
100 grams is 100 x 2.75 / 150 = 1.82% copper. which is pretty good for mining world to have this grade copper. Just a thought.
Thanks
