Download or read book How to Mine and Prospect for Placer Gold written by J. M. West and published by . This book was released on 2005-12 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased leisure time and increased interest in the out-of-doors is leading more and more families to experiment with placer mining of gold, and sometimes even to going on into small-scale production. This book supplies basic information on areas of occurrence, equipment needed, prospecting, sampling, mining, and regulations concerning the possession and sale of gold. Selected references are given for further study. Placer gold has tantalized many a person who has tried his luck and skill in the hope of striking it rich. Separating gold from embedded materials is basically simple, and can be done effectively on nearly any scale, depending upon the deposit and the capital available for investment. The final product is consistently in demand at a relatively stable price. Historically, however, one must be advised that rewards for the majority of small-scale miners-those who operate "on a shoestring"-have been depressingly small. First of all the placer miner must know where the placer deposits are located and he must have the technical knowledge to extract the gold. Additionally, he must face problems of land ownership, water supply, and water pollution, all of which have grown in complexity with the population. The costs of labor and equipment are relatively high now, although this may not seem significant to an individual mining a small deposit. Secondhand equipment may become available at relatively low cost because of a slowdown in construction or as surplus at the end of a war. By taking advantage of such opportunities, one can sometimes make an otherwise unprofitable operation successful, at least as long as the equipment holds up. To the novice or "weekend prospector," the more complex of placer mining may seem hard to comprehend. At any rate, the novice is often more interested in the recreational values offered by gold placering than in its profitability. Thus, the search for and discovery of even a small grain or nugget of gold is an achievement worth of considerable effort. As a start, the beginner may gain some benefit from visiting one of the many pan-for-a-fee tourist establishments typically found in gold-mining areas.

Download or read book Gold Prospecting Placer Deposits written by Adam Gregory Koch and published by Adam Gregory Koch. This book was released on 2013 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are countless prospecting books out there. They all teach the same general theories and show the same diagrams. While they are not bad books, in fact many are great, this book is written to take a different and simpler approach. A prospectors lifetime of knowledge is simplified and condensed into an easy to read and understand guide that will hopefully benefit those who never even held a gold pan as much as those who have spent a few years prospecting but might still have a few questions they are seeking answers to. It is the intent that this is the prospecting book that will read as a novel, and teach every bit as much as an informational guide. What are the types of equipment available and how do I use them? What is it that I am looking for when I am prospecting? What do I do with my gold once I find it and how do I sell it? Are my black sands worth anything? What are black sands made out of? How do I find a place I can go and prospect? Is there a way to know where I should dig in a stream? How do Mining claims work? These are some of the many questions that this book was written to address. While there is no guide that can tell you how to get rich mining for gold, this guide has been written for the purpose of helping you be more likely to find gold on your future prospecting trips. It is easy to become discouraged as a prospector, or allow yourself to believe others when they say "there is no gold left to be found, the old-timers got it all". You are just a few pages away from learning the facts; and that the gold has not all been taken and how you can get your share!
