Contacted Eco Lab...andHere is what they said..
"We are an assay and geochem lab. We do not process concentrate samples here at our lab, that is done by the client or his agent. When samples are sent to us, we have no control over how the sample(s) are taken or treated before they arrive here at our facility.We analyse the samples that are sent to us. If the sample is small (eg 5g) then all of the sample that was sent to us would have been analyzed.
We report our samples in grams per short ton, not metric tonne or long ton. The conversion factor from g/t (short ton) to g/T (long ton) is 0.892853143."
Now of course by me being a novice.. i have no clue what this means.. but I'm hoping someone else can make sense of this.
