Hi @hedac! Thanks for showing your interest in reading the article. You are correct it's very much fascinating!

The reason I didn't mentioned about detection of gold was because I was taking care of not making the article more lengthy as it is a very vast area for exploration! Also some of the things I explained in my past articles and some of them I have stored for my future articles.. :)

Moreover, I think I have given sufficient references about the information I shared in the article. But thanks for taking out these points for me, this will indeed going to help me a lot!! :)

Following you too!!
Cheers!! ;)
