Indicated Mineral Resource means that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.
Geothermal energy means energy contained in heat that continuously flows outward from the earth that is used as the sole source of energy to produce electricity.
Geothermal resources means the natural heat of the earth, the energy, in whatever form, below the surface of the earth present in, resulting from, or created by, or which may be extracted from, the na- tural heat, and all minerals in solution or other products obtained from naturally heated fluids, brines, associated gases, and steam, in whatever form, found below the surface of the earth, exclusive of oil, hydrocarbon gas, helium or other hydrocarbon substances, but including, spe- cifically:
Useful thermal energy means, with regard to a cogeneration unit, thermal energy that is:
Other Minerals means sulphur, lignite, coal, uranium, thorium, iron, geothermal steam, water, carbon dioxide, helium and all other minerals, ores or substances of value whether or not generally produced from a wellbore in conjunction with the production of oil and gas.
