Remote sensing involves gathering data and information about the physical “world” by detecting and measuring signals composed of radiation, particles, and fields emanating from objects. This data are collected without direct contact with the object and can be used to identify and categorize objects of interest. Remote sensing has a variety of applications.
Heavy metal is any metallic chemical element that has a relatively high density and with high toxicity, even at low concentrations. Examples include: mercury (Hg), Cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb) Cobalt (Co), Nickel (Ni), Antimony (An), Vanadium (V), Zinc (Zn), Platinum (Pt), Palladium (Pd), Rhodium.
Diamond which has its name from the Indian word “ADAMAS” meaning eternal is a high value commodity which price increase with size because big sized diamonds are rare and are worked easily. There exist many gemstones that have similar properties to diamond such as density and colour, hence making diamond difficult to identify properly. However, the hardness of diamond is unmatchable and constitutes its most distinctive property.
Element Copper (Cu) is a pinkish-orange colour element found in Group 11, Atomic Number 29, d-block, Mass 63.546 particularly useful in all aspects of electrical appliances. Geologically, copper occurs in Carbon bearing shale (Congo and Zambia), commonly as the copper porphyry deposit type as well as massive sulphides deposits.
Copper porphyry largely occurs in Chile with the biggest world deposit located in Chuquicamata. Other deposits include the Bingham (USA), Grasberg (Indonesia), Oyu Tolgio (Mongolia).
Computerized data management is one of the major developments in mineral exploration. The flow of large amount of data generated by modern instrumentation, as well as speeding up and improving decision making in mineral exploration can be achieve using computerized softwares (Moon and Whateley 2006). However mineral exploration data can be handled using either the Geographical Informations Systems (GIS) for early stage exploration data, or mining-specific packages designed to enable mine planning and resource calculations.
