Understanding Pilbara conglomerate

  1. 31 Posts.
    Dear fellow holders- I am looking to invest a bit more in this gold rush -
    though coming from non geologist background- I feel I lack some understanding of the basic problem here -compared to other gold areas-

    So conglomerate means a lot of little stone pebbles and then now and then a big gold nugget-

    Now for my understanding of this conglomerate story - drilling could probably underestimate the gold per tonne if they don't hit the nuggets exactly ??
    How do you estimate this resource if it consists of a few 15 cm large chunk nuggets and plenty of dirt in between without any gold?

    I feel simple drilling could potentially result in serious underestimation of the gold per tonne - true

    Please dear geologists -in plain English -how do we actually estimate gold per tonne in conglomerate ?
