Prospecting & Detecting
Coprolite—A Prospector's Tale
February 2014 by David C. Freitag
Gold nuggets come in all forms, but I never expected that dinosaur nuggets would too, and at a decent price.
Follow Up to "Just One More Time"
…the “One More Time” has turned into three more trips and each of the three has yielded more gold each time down.
Large Gold Deposit Types
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
Proper Spacing of Placer Sample Sites
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
Bedrock Gold: When It’s There and When It Isn’t
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
Understanding Skim Bar Placers
Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
Research and Fieldwork Yield Some Promising Gold
A week later, a small team of us hit it again, and this time the gold really showed up.
A Good Start
We split up in order to cover a larger area and found good color almost everywhere. The bedrock was shallow on both sides of the river, but the inside bend was where we concentrated our prospecting.
