Gold, Quartz & Chalcedony—Part II
November 2011
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.

Eolian Placer Gold
February 2012
I would first like to mention that I am not a geologist. I have, however, spent the last 8 years intently searching for gold nuggets with a metal detector. I have found gold in numerous locations, and in several different types of gold deposits.

Prospecting for Nickel Deposits
November 2010
The periodic exploration efforts for nickel during periods of high prices have been sporadic and incomplete. There is a role for the prospector and geologist in searching laterites potentially rich in nickel and mafic igneous bodies that may be rich in nickel.
