Thanks 1halfgram4three for posting the above blog "Prospecting for Gold" Professor Housel is amazing. I have kept it in my favourite bookmarks for future reading, there's so much information about Geology & great photos of different gemstones & precious minerals, a great read for anybody, Cheers David
