Ann: Ultra High-Grade Gold and Silver from Birdsnest Costeans, page-42

Its high grade surface gold at this stage -which is now very aptly described as ultra high grade -which drilling thus far has not yet identified a continuation of at depth. You need to go to gold fields like I have done in the Philippines or in Africa where surface grades are in the thousands of ozs /tonne with hordes of artisanal miners mining gold. As happens in most cases Aust or American companies explore at depth beneath those artisanal workings - delineate substantial ore bodies and are now very profitable gold producers.
