Nah no photos allowed as it was gold core work. You basically see if a mine is going to strike gold over next few years before everyone else does (think stock market performance impacts). Too much risk of data exfiltration given they had enough of a problem with word of mouth.
Because these results can show more information than just a single bit?
The result might not just show “not worth digging” vs “worth digging”, but something like “the gold will flow for 4 years and then only trickle for 2” vs “the gold will flow for 8 years and then nothing”.
This ^^^ We weren't drilling core for todays mining. We were sampling to see if the mine was viable years ahead and where underground would be directed over the coming months. The deeper you are or the further you are from the pit or underground path the further into the mines future you are looking essentially.
Edit: Also these are big publicly traded companies, drill reports get added onto forecasts for mine productivity which affects stock price projections & profit projections.
You wouldn't be able to know how many years exactly from the core drilling visuals, for that you'd need to assay the cores for the grades, build a mining block model and then develop a mining plan from that. It's more of a qualitative "oh dam they've struck gold a lot of it" sort of thing that would move markets. Disclosures to markets in mining need to be done publically and with proper backing of data, legacy of BreX salting their core samples and reporting the motherload of gold mines.
