Golden Legends Tales of Buried Treasure

Here is another fine PDF courtesy of E. D. Gardener and C. H. Johnson. It was published by the US Bureau of Mines in September, 1934 Includes two very clear pages of diagrams. The rocker box itself is shown in a portrait style and reads better in landscape, but you can print it and read it easily then without cracking your neck. http://kf6bxh.com/rocker.html

Since one of the most popular search results to my website is "rocker box", here is a link to a ton of photos of rocker boxes. Really, all you need is a photo to build a good one. May your next trip to the gold fields be your greatest golden opportunity. http://www.bing.com/images/search?q=Homemade+Rocker+Box&qpvt=Homemade+Rocker+Box&FORM=IGRE

Good video and Arizona gold prospecting. https://youtu.be/PT_XsmFLsU4

It is said that where there is copper, there is gold and silver. What do you think? This is a fascinating story written by a gold-prospecting enthusiast and shared by his son who knows Michigan mining. Michigan has a much unknown history of gold, and this article will wet the appetite for it. It may be time to plan a vacation to Michigan! http://jimmar.hubpages.com/hub/Gold-Mining-in-Michigans-Upper-Peninsula-Old-Gold-Mine-Open-As-Late-As-1937 Gold Mining in Michigan’s Upper Peninsula: Old Gold Mine Open As Late As 1937 - HubPages

This project utilizes a 12 volt submersible water pump (750 gallon per minute), a standard bucket, and an 18 gallon capacity tub. http://www.minnesotagoldprospectors.org/bluebowlinst.pdf Your blue bowl kit can be found at  http://www.amazon.com/Blue-Bowl-Concentrator-Pump-Levelers/dp/B003DWESAK This runs $134, and at the time of publication there were only 10 left. 4 1/2 out 5 stars. I have used one and they are worth the money, as panning dirt is laborious. This device separates concentrates while saving time and energy (labor).

This excerp was taken from  http://www.minelinks.com/alluvial/dry_washer.html This is just a small portion of the information you can get at the link site above. But in the interest of time for those of you who understand the drywasher and what you want to build, here are the important numbers to remember! "In contrast to the single-weave canvas, silk or rayon permits a good extraction of gold, but too much dust goes through into the bellows. Heavier canvas is too tight for good separation. Copper-wire fly screen is used under the canvas. The riffle box is 11 inches wide and 40 inches long and contains six riffles. The slope of the riffle box is 5-1/2 inches to the foot. (Hand-operated machines are usually much smaller and the riffle box is set at a steeper angle than with powered machines.) The gravel and sand are shovelled onto a screen with 3/8-inch openings at the top of the washer. The bellows is operated at 250 pulsations per minute; the stroke is 3 inches. The capacity...

This video offers free construction instructions of a super sucker; if you watch this it does a good job of demonstrating how to make the build. Reed Lukens provides a written set of instructions that are excellent. If you want to learn about gold prospecting, this gentleman has 146 videos.You can skip from one to another and learn a heap of stuff. I highly recommend. http://www.youtube.com/watch?feature=player_embedded&v=f8Penqua6R8
