Curious as to the meaning of some Atomic Absorption Analysis assay results I am looking at, any help would be appreciated.
Specifically the last line "AuSw" appears for these samples only, none of the other samples have an AuSw line.
Some of the other sample results came back with higher ppms for AU but no AuSw line?
These are from quartz vein grab samples containing copper and iron oxide.
