I think you are underselling it a little .. Remember that all holes are true width only (Don't know whether your SYR Holes are True width) but TON High Grade zones (In fact all Ton zones stated ) continues for "at least" 500m down at depth (400m of which is mineable via a Open Cut given we are on a 250m high hill)
So assuming 40m wide over 500m Depth x 5km Strike length with Specific gravity of 2.7 is
500m x 40m x 5000m x 2.7SG = 270 Mill tonnes @ that grade
....assuming 5km length (Currently confirmed over 3.2km)
Does not factor in Charmers /Black hills either which are known to have 18% Present not drilled yet
