Geophysics in Mining Exploration
One of the most interesting series of corporate videos that I have run across have been put together by John-Mark Staude of Riverside Resources (RVS.V). His geo-tutorials walk investors through the mineral exploration process. (I've posted several them here on my blog). The exploration process uses many tools and industry professionals sometimes assume that their investors are going to know what all of them mean.
The 6th video in the series covers geophysical exploration methods.
If you want to approach investing with a "beginner's mind", these videos are awesome. I'd love to see a series of videos on the mining finance side (what happened to the "bid crusher" video?) but the dark side doesn't like too much attention.
