Metallis has drilled several holes into the area and have come up with long intercepts of mineralization, albeit not at a grade high enough to attract a lot of attention yet.
Chief Geologist, Dr. Razique noted "Our updated 3D geological modelling and structural reconstruction has revealed that the Cliff is a substantial porphyry system capped by a series of northeast trending sub-parallel mineralized zones linked to a much larger magmatic-hydrothermal system underneath".

Can you comment about the grade of mineralization in the system at Cliff?

The company further explains: "Metallis is sitting on a Complete porphyry system – Top to Bottom. The system runs ~7km in length and pinches/swells from 150-300 meters in width along the whole thing. Last years drilling has confirmed continuous mineralization at the upper levels for 4kms in the south and at Cole at the northern end, drilling in the middle will help show its continuous thoughout. Erosion has removed small portions of the system but this has facilitated better understanding. Recent drilling and surface has exposed (outlined) the upper part of the high grade potassic core to date but still pretty shallow. By analogy to most porphyry systems in the Golden Triangle"
The expectation is that grade
to improve with depth (1km) and increase with width - as is common in the Golden Triangle.
