yesterday I wasn't sure if I had decent photo of the tourmaline at this spot. This isn't great, but if you enlarge the photo to full size and look at the darker areas below and to the left of the hammer's chisel tip, you can see acicular (needle-like) black crystals. That's tourmaline. Definitely not jewelry quality. And course, plenty of pyrite and possibly other sulphides shot through the rock. I have rarely seen galena and sphalerite at Quartzville, but the only sulphide I've been able to identify with full confidence at this quarry is pyrite.
