The Angry Geologist

In his own words, per the interview with Global Mining Observer, another quality blog (which doesn't have an RSS feed yet unfortunately):

"My idea behind the blog was to try and help average investors to better understand the technical data presented by exploration companies, remove the technical jargon and present the data in a way that it is easy to understand, to show where potential problems can exist and identify potential upside in a project."

My opinion on The Angry Geologist: I like the way how he analyzes and explains things thoroughly and gets to the essence of a resource (as far as I can see as a non-geologist) by the information available to that point, and I especially like his use of software like Leapfrog, which is professional geo software used to build resource models, to guesstimate resource estimates.
