Good on you for having a go but as I wrote in my last post, you need to take great care with the way you interpret JORC resources/reserves. Using generalised weightings depending on the resource/reserve status of a deposit is being too simplistic imo. My experience as a geologist with LFB goldies has been that ounces increase going from what is predicted at the resource stage to what is recovered by mining. For MCO, this grade factoring is up to 2.5 and for HEG it is likely to be at least 1.5.
I disclose that I have holdings in both of these companies.
