The paperclip comparison for one gram per tonne is a great way to picture grade. The heap leach entry is a useful one for newcomers too, since the US Bureau of Mines did much of the early work on heap leaching low-grade gold ore in the late 1960s, which is part of why so many small oxide deposits became mineable. The line that inferred ounces are mostly hope is one every new speculator should keep handy.
Thank you. Plain, simple language with just enough humor to denote a need for wariness. One of the best explanations of basic mining terms. Every investor should read/reread this piece. Look forward to #s 2 and 3.
As long term miner back in the 70s and 80s I can confirm that this primer is accurate.

Great overview as always, John. Practical and well-written. Look forward to subsequent installments.
Calling everything before the assay guesswork or hype changed how I read press releases.
Excellent, thanks :)
fascinating. Every industry has a niche.
