Depending on your browser and what other tools you have available to you you can try to print the page and zoom into your contents either prior to or after saving the document (PDF usually works best). There are also many tools available online and on some computers that allow you to "screen grab" or "capture" an image online.
These might be your best online options besides saving the actual Mining Guide Updates from the Pick & Shovel issues themselves. Thanks for understanding our efforts to protect the value of everyone's memberships by securing these pages from illicit reproduction until we find a better solution.
Good luck out there and happy prospecting!
