Mining Prospecting and exploration BritannicaProspecting and exploration Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit.

mineralsthe prospector of today has advantages which to some extent make up for the increased difficulty of finding ore deposits. one of these advantages is a greatly increased knowledge about the geologic factors that have localized ore deposition. but the search for new deposits has become a complex undertaking, and the prospector should be as well informed as possible. he should acquire the ability to identify not only ore minerals, but also common rocks and their minerals, and he must be familiar with the main kinds of geologic structures. this knowledge is best acquired by academic training, but much can be obtained through use of such reference books, and others listed at the end of this booklet. geologic reports and geologic maps of areas of interest should also be studied. topographic maps or air photographs of areas to be prospected should be obtained and used to plot sample locations and other appropriate data. a prospector can outfit himself in various ways according to his means see full list on 911metallurgist.com many mineral deposits are not exposed at the earths surface. they may either be concealed by thick soil cover, or they may lie buried beneath layers of rock. to find these deposits more complex techniquesbased on geochemistry, geophysics, and geobotany can be very helpful. most of these techniques require specialized training and, in some instances, expensive equipment. geochemical prospecting is based on systematic measurement of one or more of the chemical properties of rock, soil, glacial debris, stream sediment, water, or plants. the chemical property most commonly measured is the content of a key trace element. the purpose is to discover zones in the soils or rocks that contain comparatively high concentrations of particular elements that will guide the prospector to a hidden deposit. such concentrations of indicator elements in rocks or soils constitute a geochemical anomaly. the actual amount of the key element in a sample may be very small and yet constitute an anomaly see full list on 911metallurgist.com geophysical prospecting combines the sciences of physics and geology to locate ore deposits. familiar examples of geophysical prospecting include the use of geiger counters for detecting radioactive uranium deposits and magnetic surveys to find iron deposits. five major geophysical methodsmagnetic, gravimetric, electrical, radiometric, and seismicare successfully utilized in mineral exploration. some of these methods require complex and costly instruments and highly trained operators. others, however, are relatively simple and inexpensive. among these are the magnetic and radiometric methods described below. see full list on 911metallurgist.com plants have been successfully used as aids in mineral prospecting, and under certain conditions may assist in locating buried mineral deposits. so many factors are involved, however, that it is not always possible to predict conditions under which plants will be of practical assistance. many plants, by means of their extensive root systems and the absorptive ability of their roots, effectively sample many of the elements that are within reach of the roots and transfer these elements to the branches, stems, and leaves, which can be chemically analyzed. thus, under ideal conditions, the plant has sampled the underlying soil or rock in its root zone to depths of as much as 50 feet. the advantages to the prospector of being able to sample plants and thus obtain information about the metals that occur at considerable depth are at once obvious, although problems in interpreting this information may render this method of prospecting impractical under many field conditions. for a review of see full list on 911metallurgist.com once a promising mineral deposit is discovered, the prospector must know whether the deposit can be staked, purchased, or leased. on privately owned land, the mineral rights must be obtained from the owner, generally through purchase or lease. the acquisition of mineral rights on public land is regulated by state and federal lawsthese rights are generally obtained by staking a claim or by leasing the land from the appropriate governmental agency. federal mining regulations are administered by the bureau of land management, which has issued several pamphlets of interest to the prospector. these include, information in regard to mining claims on the public domain, and circular 1941, lode and placer mining regulations, and they are available free of charge from the information office, bureau
