Probably drill assay results.
Expect Nickel and Copper results from massive sulphides.
My view is that Cu MS's could be as high as 8% (but probably 4-5%) and Ni MS's could be running between 2.5 and 4%.
My view based on the data provided by SIR to date and mineralization in brecciated sulphides + current exploration.
If numbers like these come out the whole MC of SIR will have to be re-written AGAIN aftyer only 8 weeks.
