A New Method for Handling Stubborn Gravity Middlings
July 2016 by Gavin & Randy Clarkson
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.

Preserving the True History of the Ivanhoe
April 2019
My partner had the contacts and it wasn’t long before we had an agreement in place and the company had a geologist on site. I recall a time when he was getting the lay of the land, so to speak, and he broke off a rock sample and inspected it with his magnifier.
Who is a Qualified Person?

So you think you have an ore deposit? The work has been long and hard, but there are a few drill holes, lots of samples and assays. The data is in a reliable computer and there may be a mine at the end of the tunnel. What is the likelihood of a profitable operation? Can you raise capital for development or exploration?

Proper Assaying of Placer Samples
November 2012
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.

Small-Scale Processing of Hard Rock Ores
December 2014
Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that may be present.
