Gold assays

Hi, does anyone know much about gold assay readings. Wonder if someone could shed some light on one for me. I realise it's not a lot of information but any information, good, bad, encouraging, nothing special I would very much appreciate it. Thank you.

7 metres at 4g/t and 24 metres at 3.05g/t. Shallow gold deposit identified - estimated 300,000 tonnes grading 2g/t for a potential 19,000 ounce resource
