Image 4: PIU-04 349.79 – 355.0 m. Volcanic andesite host rock with strong biotite-magnetite alteration and consistent quartz-sulfide veining. Hole PIU-04 has significantly expanded the footprint ...

however local zones of magmatic-hydrothermal breccia with biotite-magnetite cement occur. Below 570 m the hole intersected intervals of the quartz-bearing "causative" porphyry, similar to those ...

Brecciation is predominantly pre-mineral magmatic-intrusion breccia, however local zones of magmatic-hydrothermal breccia with biotite-magnetite cement occur. From 570 to 660 m and again from 810 to ...

The hole encountered 24 meters of overburden before hitting a mineralized semi-crowded feldspar-biotite-quartz porphyry with quartz-magnetite-chalcopyrite-pyrite veinlets along with remnant patches of ...
