Digging into the historical reports for the area a bit deeper. I wanted to look more closely at that spectacular reading of 1640ppm. I can't find the document at the moment but from memory SIR's anomolous readings were in the hundreds range not the thousands..
This following from wikipedia explains one of common geochemical signatures associated with komatitie nickel deposits.
the Kambalda Ratio Ni:Cr/Cu:Zn identifies areas of enriched Ni, Cu and depleted Cr and Zn. Cr is associated with fractionated, low-MgO rocks and Zn is a typical sediment contaminant. If the ratio is at around unity or greater than 1, the komatiite flow is considered fertile. Other geochemical trends sought include high MgO contents to identify the area with highest cumulate olivine contents; identifying low-Zn flows;
How does that compare? The assays from that particular sample are: Ni: 1640ppm Cr: 655ppm Cu: 76ppm Zn: 28ppm
That gives ratios of Ni:Cr - 2.5 Cu:Zn - 2.7
As an academic exercise I scanned through all of the soil samples and picked out all the ones with Ni reading greater than 50ppm. Of these I calculated the Ni:Cr ratio (sorry I didn't do Cu as there was a lot of pages to scan through).
Remember these were spaced on 1km grid so they were looking for trends not particularly high readings. I found 78 samples and of those 51 had a ratio >= 1. The average ratio for all positive reading was 1.62 ranging up to 4.45. To say zone is prospective is an understatement.
To put that all in context those drill samples covered a huge area. Basically the entire area with the black boundary on this map. The red is BFE tenements and the southern one is partially included in this zone. The northen one with it's cluster of faults running through looks even more tasty to me.
