The gold mineralization occurs within a broad zone of disseminated and fracture-controlled sulphides within a volcano-metasedimentary package of variable composition. The main sulphides are pyrite and pyrrhotite, with the former typically predominating. The mineralized zone is generally low grade (0.25 g/t Au to 5 g/t Au), is up to 120 m wide and stretches for more than 1.6 km along strike. It is characterized by local silicification but lacks lithological control and quartz veining. The broad zone encompasses multiple/variable host rock metasedimentary horizons and subordinate intrusives of acidic to intermediate composition, all of which display feldspathic, chloritic and biotitic alteration. On the basis of the mineralization features, Micon believes that the deposit is associated with an Archaean-age copper-deficient porphyry system.
Porphyry system is being suggested. The mineralizing fluids ascended from the SE and reached surface at around the Section 0m. There a good chance that a higher grade zone exists trending SE towards the source of the mineralization (i.e. pluton). Unfortunately, Probe need's to acquire the claims they do not own (immediately adjacent to their deposit) if they want to even attempt to mine the high grade at Section 1200SE and beyond.
Once these claims are in their stable, underground extraction of the high grade is possible (I would venture a 3g/t cut-off would do the trick for a near surface deposit). The production profile/grade of the project would change significantly as both high grade (U/G) and lower grade (pit material) would be extracted simultaneously.
So to recap...there are 2 missing pieces I am most interested in:
1- Getting the claims they are missing around the lake, and
2- Demonstrating that the high grade (>3g/t over 30 meter) continues underneath the lake.
