Mineral Exploration and Prospecting Quiz

Geochemical Prospecting

• Geochemical prospecting is used to trace ore deposits and mineralization.

Coal Properties

• The most important quality specification of coal is its calorific value or energy content.
• The measure of coal is expressed in terms of its energy content, usually in kilojoules per kilogram (kJ/kg) or British thermal units per pound (Btu/lb).

Cement Production

• Aside from limestone, clay is another raw material necessary in the production of cement.

Diamond Drilling

• For accurate logging of diamond drill cores, it is essential to ensure that the core is properly oriented, logged, and sampled.
• A stratum of coal or coal bed is called a coal seam.

Exploration Methods

• The most effective method of exploration for developing or delineating an orebody to define ore reserves is diamond drilling.
• Initial reconnaissance exploration is usually conducted in areas with favorable geology, such as along structural trends or near known mineral deposits.

Diamond Drilling Equipment

• The cylindrical chamber for receiving and retaining rock samples as diamond drilling progresses is called a core barrel.

Core Sampling and Preservation

• The system that preserves diamond drill core samples for future references while providing adequate samples for geologic interpretation and grade establishment is called core logging and sampling.

Hand Sampling

• The hand sampling procedure that yields the most accurate results with the smallest possible error is the channel sampling method.
