Smelter Payday Countdown, page-83

In the photos of the DSO to be shipped we could see a minimum of 5 containers @ 25 tonne a piece grading 85 to 95% Cu of +40mm. I'm thinking of how many tonnes at what grade had to crushed to achieve this. When the company did the bulk test only 7.25% was above this size so if you do the math on what you think the grade was you start to come up with very high tonnage and a lot of product that falls outside of that +40mm. Well worth while revisiting the report of the bulk testing IMO.

"The native copper sample consisted of large diameter PQ (83mm), diamond drill core from 32 holes; a total of 2370m from across the native copper zone. The material was crushed and put through the HPGR, with Page 9 Fig 19: Removal of magnetite via Magnetic Separatorsome of this material kept in reserve for additional work. The head samples contained a total of 3% Cu (2.33% Cu as native copper and 0.67% Cu as sulphide copper). The cobalt content was 660ppm. However as found with the previous bulk sample test of the native Cu ore, representative sampling of nuggety deposits on a large scale is extremely difficult and a higher final grade is expected"
