Predicting rock type and detecting hydrothermal alteration using machine learning and petrophysical properties of the Canadian Malartic ore and host rocks, Pontiac Subprovince, Québec, Canada

•Physical properties measurements of 819 samples from Canadian Malartic deposit.•Hydrothermal alteration is marked by formation of pyrite from Fe-bearing minerals.•Hydrothermal alteration mostly affect sedimentary rock magnetic properties.•Support vector machines can predict rock type and alteration from physical properties.•Conceptual petrophysical models are proposed to guide geophysical exploration.
