Everest Metals catches a golden wave at Revere as bulk sampling
Additionally, it expects to deliver meaningful gold recoveries from the program using a simple gravity gold circuit for processing Revere ore as well as generating a substantial inferred (and possibly indicated) resource through the conversion of historical high-grade mineralisation results (17g/t to 325g/t gold). Processing of the bulk sample ...

The samples can be assayed for several elements if there is not any economical restriction, otherwise the assays must include at least gold and silver. In this way we can know a preliminary distribution of metals. For example, of 100 samples collected the average gold value can be 2 g/t, with 40 samples reporting more than 1 g/t gold.
