In most locali- 18 2011 Schedule of Events ties the top 4 inches of soil has been pretty well depleted 19 Contact List of older coins. To reach the depth where the remaining coins reside requires a detector that has excellent ground balance capabilities to minimize the effect of minerals on the electromagnetic field of the detector coil. The field must reach deep enough to detect the coins. The detector must also be sensitive enough to provide a good signal at that distance from the coil. The general rule is that if it won't detect it in the air at that distance, it won't detect it in the ground. To qualify this, it is nec- essary to do air tests in a location that doesn't have elec- tromagnetic interference in the air. This can sometimes be a challenge. To make the choice of the right detector you must take into consideration the locations you will primarily search. Mountains may require a different detector than the prairie or farmland. Red iron rich clay soil will probably require a different choice than black humus rich farmland. Alkali soil, salt water beaches, clay rich soils, and abundant black magnetic sand all create their unique problems for the coin detector.

Setting up the Hopper / Frame Step 1: Your drywasher may have slightly different frame components than the illustration but the easiest way to as- semble a drywasher is usually to place the Hopper on the ground upside down. The upper part of the front and rear legs are at- tached to the hopper and need to be lifted so that the point where they intersect can be bolted together making the frame rigid.

We have improved the standard Power Jet and created a more efficient, easy to use and over-all superior jet! The new design involves a slight enlargement of the jet tube, making it a bit larger than the interior of the suc- tion hose. This modification creates a smooth, seamless flow from hose to jet. Rock jams and other obstructions are virtually eliminated providing less downtime. The quick coupling fea - tures two side mounted snap levers for quick and easy joining. Each oversized power jet comes with the suction hose quick coupling. Available in 2, 2.5, 3, 4, 5, 6 and 8 inch Jet sizes.

  • The Dry Washer Featuring Model 151 & Model 140 by James Klein
    The Dry Washer Featuring Model 151 & Model 140 By James Klein Dry washers are most popular in areas where water is not available, such as dry washes and desert areas. A dry washer utilizes air, vibration and static electricity to very effe c t i v e l y separate gold from the waste gravel. The use of vibration to move mate- rial through a sluice box is similar to the same movement created by water ve l o c i t y . This method of dry recovery can be extremely effective when the proper balance of air separation and vibration is employed. The concept of air separation is also vital to proper dry recovery, as vibration alone cannot create proper separation. Keene has employed an adjustable oscillation system that cre- ates a balanced vibration and air flow. If air is induced properly it can create a static charge that will create a conduc- tive field that will attract only heavy met- als such as gold. This static charge is created when it is forced through a spe- cial fibrous material that lines the recov- ery trough of the dry washer.

  • Bird Tailings
    BIRD TAILINGS Volume 34-6 A Monthly Newsletter Published by the RoadRunner Prospectors’ Club June 2020 President’s Corner Hello everyone. I hope everyone is well and staying safe. It seems like a lifetime since we have gathered as a group, whether at an outing or monthly meeting. I, for one, miss both events. It looks like we are in for more changes in our way of life. I hope it is temporary, but we will have to endure this situation a little longer. The Board of Directors is still hesitant to have a general meeting of the members. We have discussed how to have the June night dig and have it safe. At this time, the Board does not feel it would be a good idea to have the dig. It would be hard to control the dig site and keep the distancing that is needed. Also, we feel we would be putting the organizers of the event in jeopardy. I know that a lot of new members have joined the club so they can participate in club activities. The Board is deeply sorry to cancel all these events, but we hope you under- stand. The Board members are also members and like to participate in these events as much as the rest of you. We miss them as much as you! We will send out mass emails, announce on our Facebook page, and our web site, www.roadrunnergold.com, of any changes, so stay tuned. I would like to give you some statistics about the club. Did you know? As of today, we have 1264 active members.

Our underlying goals are to foster science literacy and arts education through structured activities that are engaging and challenging and by which kids—and the adults who mentor them—learn while having fun. INTRODUCTION . Philosophy behind the FRA Badge Program & Suggestions on Using It I’ve developed this manual so as to enable the American Federation of Mineralogical Societies to sponsor a youth program via Future Rockhounds of America, a program that rewards kids on an on-going basis as a means of encouraging and cultivating their interest in the earth sciences and lapidary arts. Through this, we’ll uphold our chartered goals as nonprofit, educational organizations by actively seeking to foster and develop science literacy and arts education among our youngest members. My guiding philosophy has three underpinnings. They come from both my own values as a person invested in the positive development of young people and from a wealth of research indicating that if one wants to design and deliver programs that effectively promote positive development among young people, three steps are crucial to enact.

    Rockhounding and Prospecting in The Southwest Thomas Farley Copyright Page Dedication To The Best Parents a Son Could Ever Have Acknowledgements Special thanks to Linda Dodge, Summer Wintemberg, Donna Pollard, Rolf Luetke, Drew Barkoff, Bryan Smalley and Sharon Artlip. The dozens of my other helpers are mentioned at various places in this book. My appreciation cannot be expressed in words. Introduction Welcome to rockhounding and prospecting in the Southwest. This book introduces exploring, discovery, and collecting of all things rock related. It is not a gem trail guide, rather, this title accompanies, makes practical, and expands on those guides. Most importantly, it outlines the tools needed for the rockhound to make their own guide, current every time. This book demonstrates the map and vehicle skills needed to get to traditional collecting sites but it goes beyond that. It shows how to find new places and different materials old guide books don’t mention. Few guides describe variscite, rare earth minerals, pegmatite rock, or unusual rocks in general. This book does. The great hope is for this title is to go further than any guide, to let the rockhound or prospector find their own path to discovery and joy.
