10 questions when picking junior miners
This article by author Allan Trench, appeared in the March 2013 ASX Investor Update email newsletter.

3. Are the projects of significant scale?

Understanding this aspect of a screening process for explorers requires some geological knowledge.  Scale in this context does not simply relate to the area covered by a company's exploration projects - although, everything else being equal, larger areas (100s to 1000s of square kilometres) are better than smaller areas (1 to 10 square kilometres).
Scale in this context relates to the "size of the prize" if exploration is successful.  In gold, for example, does the company see potential for a 20,000-ounces per annum mine or 100,000 ounces?  The latter is better.
In copper, that could be 20,000 tonnes per annum production or else closer to 100,000 tonnes. Again the latter is better.  The geology of different deposit styles tends to drive what is possible in terms of potential production levels.  Everything else being equal, bigger is better.

Think Ancuabe and multiple leases in Mozambique.
TON did their homework IMO.
