Just be aware that if a company decides not to define JORC-compliant resources, then it can't keep its investors updated on what resources/reserves it has. It thus means you will be placing a great deal of trust in management who will be restricted to making statements like "it's all OK", "there's plenty more like that" and "trust me I'm a mining engineer".

The Scoping - pre feas - full feas route is tortuous, but if done properly injects some rigour into the process and acts to highlight any weaknesses or areas of concern BEFORE you start mining. A bunch of dudes in Perth and China plucking numbers out of their backsides and venturing off-piste would be funny if it was just their own money they were spraying up against the wall.
