Gwen Preston is the Resource Maven.

Years as a mining journalist gave her a deep base of knowledge and a broad network of contacts in the resource sector. She understands which projects and pieces of news matter. She understands what it takes for a project to advance along the exploration-development-production path and what opportunities each stage offers.

She knows how the metals markets work, alone and within the global economy, and how to profit from commodity cycles.

Resources are Gwen’s world and she seeks to pass that knowledge on to others. Contact:


What Subscribers Say?

Besides your far superior record, your format is the best I’ve seen in PM newsletters.  It’s so easy to go back for older info on companies when appraising my portfolio.  This compliment is from someone who has hired about a dozen letter writers so it has perspective.  Keep up the good work.
