I am not too good on the "Drilling Results".

Can someone tell me what this result actually means.

BBUD329: 4.7 metres @ 462.1g/t Au from 244.0 metres.

Is this number 462.1g/t lasting? and if so for how long. There just seems to be a very a large discrepancy in many of the numbers reported.

Many of the older mines, like "Newmont" for example would be lucky to get 2g/t. Their current costs of production, currently are around USD $1900.00 oz.

???

Thanks, in advance.
