Channel/trench samples are generally taken across a mineralised structure and clearly PRA have got something. However, it is customary, necessary* even, to report widths not just a point assay. How many trenches or channels were cut, how wide were they, how was the sampling done, how many assays are there, and - more to the point - how wide are the significant intercepts? Again this lack of critical information makes me shy away from this one.

I think my OP and subsequent post put it quite clearly. Has this company got an exploration target or not?

*look at the "Reporting of Exploration Results" section of the JORC code
