Abstract: 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.

Abstract: A method of coating a masonry product or structure, in which a single coating of a tinting composition is made on the exposed surface of the masonry product or structure that maintains its look, feel or texture, the masonry product or structure being chosen for suitability by passing one or both of the following tests: A) Wet Area Method: 2 milliliters of water discharged onto the masonry surface within one second at 20-25° C. Will wet out approximately 6 to 34 square centimeters (1 to 5 square inches) of the masonry surface in one minute, or B) Total Absorption Method: 2 milliliters of water discharged onto the masonry surface within one second at 20-25° C. is completely absorbed into the masonry surface within the period of 10 to 60 seconds. The preferred tinting compositions are aqueous latex emulsions.
