Method, system and apparatus for use in locating subsurface ore bodies

摘要

A method and system for locating subsurface ore bodies. Samples of near surface soil are collected over a predetermined geographical area. The samples are analysed to discover any chemical anomalies in the dust particles as a way of identifying possible subcropping mineralization. A tine (22) and collection tube (24) engage into subsurface soil and samples are drawn up the tube into a dust collection module (12). Sub 5 micron particles are captured on an electrostatically charged tape (40). Consecutive samples are indexed on the tape e.g. with a barcode. Collected dust samples are ablated by a laser ablation cell (72) and the ablated sample analysed by a mass spectrometer for presence of ions indicating presence of a resource body, such as a body of ore, minerals or hydrocarbons.
