Composite strip log with downhole lithology, copper, tungsten and molybdenum geochemistry, alongside LWIR and SWIR spectral classifications of key alteration and skarn minerals. A spectral domain classification computed through waveform tessellation uses abrupt changes in TerraCore’s spectral data backed by lithogeochemistry to identify unique zones of alteration ranging from high-temperature hornfels-altered siltstones and garnet-altered limestone in the upper hole, to intense dolimitization in the lower part of the hole, including around the copper-rich diorite porphyry at 610 m. Of note is that many hydrothermal alteration assemblages are obscured by a Tertiary hydrothermal argillic overprint related to nearby volcanism.
