A method of assaying the compressive strength of rock comprises testing a primary plurality of rock samples of similar lithology, at least some of which have different porosities, to determine, for each sample respectively, values corresponding to compressive strength and porosity. A first series of pairs of electrical compressive strength and porosity signals, the signals of each pair corresponding, respectively, to the compressive strength and porosity values for a respective one of the samples, is generated. These signals are processed by a computer to extrapolate additional such pairs of signals and generate a second series of electrical signals corresponding to compressive strength as a function of porosity. The second series of signals may correspond to unconfined compressive strength, and may be further processed to generate a cumulative series of signals, using electrical adjustment signals corresponding to other conditions affecting the compressive strength of the rock.
