1. A method of measuring at least one property of a material from a wellbore, the method comprising:
obtaining at least one sample of fluid including at least fines from a downhole environment;
exposing the at least one sample to a magnetic field produced by a nuclear magnetic resonance (NMR) spectrometer;
measuring a magnetic susceptibility of the fines in the at least one sample in response to the magnetic field; and
identifying at least one mineral present in the fines based at least partially on the magnetic susceptibility.
