Richard Schodde at Minex Consulting - Enough new mines / Cost of Discovery / Delay from Discovery to Development / Commodity Prices vs Exploration

I have previously linked to the excellent presentations by Richard Schodde at Minex Consulting......

Sprott have just published an article reviewing some of Schodde's work questioning whether we will have enough new mines.

There is much more at the Minex site worth attention  with plenty of graphical presentations for example

• Key issues affecting the time delay between discovery and development
• The impact of commodity prices and other factors on the level of exploration
