Tomichi is a porphyry copper-molybdenum deposit that has all the characteristics of porphyry systems including multiple intrusions, zoned hydrothermal alteration, and multiple stages of veining and sulphide mineralization. Mineralization is characterized by disseminated and fracture controlled molybdenite and chalcopyrite hosted by a mid-Tertiary, potassic altered, intrusive system dominated by a porphyritic quartz monzonite. The mineralized porphyry is exposed at surface on top of Copper Hill. Diamond drilling has intersected copper-molybdenum mineralization over a surface area in excess of 1,500 metres by 800 metres, to a depth of at least 600 metres and remains open to the north, east and at depth. Many drill holes were terminated at depths ranging from 300 to 400 metres below surface in economic mineralization.
