Prospecting for Pegmatites

What many people don’t realize is that the Comstock Lode produced over 8,000,000 ounces of gold…
Mining Pegmatite Deposits
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Gold Placers of the Kenai Peninsula, Alaska
The biggest obstacle is that like many streams on the Kenai Peninsula, high water during the summer months from snow melt and rain can make dredging nearly impossible. The best dredging is in the colder months of the year.
Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
Sierra County Gold—Part II
...we will continue our examination of the rich streams and mining districts, and then take a look at some of the big nuggets that have been found here.
