Hard Rock and Placer Gold of Manhattan, Nevada
October 2019 by Chris Ralph
He found 5 to 7 feet of gravel containing half an ounce per yard. This started a rush of placer activity and several other shafts were sunk, with some large multi-ounce nuggets being found.
Understanding and Prospecting Benches
The most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.
Rare Silver Nuggets And Their Origins
Silver nuggets have been described as “ultra-rare,” “prized” and “unique.” Naturally occurring silver nuggets are rare enough to suggest caution when purchasing. Fakes have reportedly been produced and misrepresented for sale as genuine specimens.
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.
Perception of Mining vs. Reality
How Mesothermal/Orogenic Gold Deposits Form
These deposits are very widespread across the planet. In fact, they are so extensive that something around 75% of all the gold ever mined comes from these types of deposits (if one includes the placer deposits that also formed from them).

Placer Gold Deposits of New Mexico
While a large number of locations have yielded some placer gold, most of the state’s placer production has come from a few productive districts.
