Siliceous Rock Found At Nundle, New England, NSW.

A good Friend & fellow group member came to our Winter Solstice Masquerade Party yesterday bareing gifts, two pieces of soliceous rock which he picked up in Nundle at the gold mine. The images here are of the larger piece. Believed to be Australian flint, I think it looks more like quartz. Whichever it is, it would be great for gun flints or flint & steel fire lighting.
