This line stuck out for me in the last ann:

“Silver metal was added to the smelt in flux A in this sample (TERC-006, 26-28 metres) to test whether this would aid the extraction of gold into the copper bar. The levels of silver recovered for this sample were below the quantity of silver added.”

By below, they mean zero silver was recovered from the sample when they added silver. But the sample did yield 37 gpt of gold.

I asked a metallurgist friend a while back and he simply said there wasn’t enough information available to go on and that he didn’t have enough time in the day to investigate what they are doing.

There has been more information released since then, so I’d be interested to hear his (and others) opinion again.
