I have the 2020 50th anniversary edition mining guide. Is this the most recent edition? If not, how do I go about upgrading? If it is the most recent, how often do they put out a new guide?

I find that the guide is a lot more helpful on claim boundaries than the website. Many of the website claims only have an ingress and a center point (sometimes). When they are in the guide, they tend to have more information........or is there some secret menu online that I don't know about where I can access it all? lol


Thanks, Robert
