@hiblue by my reckoning PPM in gold parlance equates to grammes/tonne so 1,000 ppm would be 1 kg metal/ 1,000kg ore or 0.1% in this case Copper. Clearly these are soil samples so you would expect them to be less than an underlying ore body.
It is always worth bearing in mind that Sentinel mine resource grades at 0.5% Cu and that is profitable, so soil samples of 2,790ppm are half the grade of a working profitable nearby mine which in my view bodes very well indeed for ARCM.
DYOR, but happy to be corrected if you think my maths is out?
