Resource: Identified: geologic evidence suggests the location, quality and quantity of a resource Undiscovered: a material that is surmised to exist based upon broad knowledge and theory –hypothetical and speculative

2.Reserve: part of the resource that can be extracted economically –Measured: amount is known from a working mine –Indicated: amount is known from a sample data –Inferred: estimated amounts based upon similar experience
