    Description
    The sampling and the estimation of the gold present and recoverable play a very important part in the history and development of all placer deposits. For this reason everyone interested in placer mining should know the best methods of working this class of mineral deposit. The purpose of this bulletin is to indicate and describe to the miner and to the layman the best general methods used, so that they may understand and know how to do each and every part of the work, as well as to make the necessary calculations. The work may be divided into three general subdivisions, namely: (1) The Sampling of the Deposit, (2) The Testing of the Samples, and (3) The Estimation of the Total Gold Present and the Gold Recoverable in the Deposit. 17 p.
