If I have 10 drill intersections of grades that appear to be above most mines average grade, is there an ore reserve there?
Firstly you need to establish that the resource has continuity and that your information is representative of it. However, for a deposit of any size, it would have to be very uniform and consistent for continuity to be demonstrated by only 10 holes. Secondly, if the resource has substance, the mining method, mining costs, treatment method, treatment costs and metal recovery need to be established.
