    Hey TC

    Just saw yours & FHs convo on grades etc.

    No Geo so any discussion & ideas / thoughts is always great to read.

    This interval calc could be handy tool as well https://corebox.net/drill_interval_calculator

    Though who knows if I'm working it right but found it interesting. By the way fyi the web certificate is not up to date so you should get warning on it if go to the website if your security kicks in.

    "This calculator is a first pass tool for determining what might be ore and what might be waste. That determination (ore vs. waste) has enormous implications regarding the exploration potential (the size) and eventual value of a prospective property.By knowing the average grade of the excluded material we can tell if the company has been pushing high grade assays into very low grade rock (smearing) or if the long interval is actually representative of the entire quoted drill interval"

    "Often news releases that announce drill results report a long interval grading “X” grams per tonne gold (or any metal) over “Y” meters. The Y interval may contain smaller, higher grade intervals within; this is generally indicated by a statement such as: “Including __ grams per tonne gold over ___ meters.” Although this is useful information it only tells half the story. We also need to know what the rest of the interval grades when the high grade intervals are excluded. Would the excluded interval make money (ore) or lose money (waste) if it were mined?"

    I found it some time ago from a link on the Angry Geologist from memory

    http://angrygeologist.blogspot.com/2017/03/

    I do recall his blog at the time re smearing caught my cynical eye tongue.png and it is also below for a read.

    Anyway...just throwing out there as a possible tool some may wish to play with to see if relevant or not.

    Using say the current topic MKG eg on NARC 145 & 143.
