An exceedingly, high grade chunk of gold mineralization! The piece is composed of bright gold, streaking through a matrix of, predominately pyrite. As well though, there are clots, to 9mm across, of a grey, micaceous telluride, near the centre and back of the piece. Also, there are black patches of small tourmaline crystals here and there through the pyrite. Very small amounts of quartz.
The Beaufor Mine is a past producer that gave up 1.2 million troy ounces of gold before production was suspended a few years ago. Sawn on one side to better reveal reveal the gold and telluride mineralization. I estimate 0.75 troy ounce of gold in this piece. Dense!!
