Download credits are obtained by submitting useful information back to us that we can use to improve the accuracy of our existing models - or even build new ones. Registered users are issued with a user ID and password that gives them access to all mine models posted to the site. Each mine model download is charged to users at the price shown beside each model listed on the Mines Download page. There are no other charges. There are no membership fees.
Registered users receive a short monthly email report advising of model additions and revisions.
The monthly email also helps us to keep track of subscribers. If you do not wish to receive the monthly email report, you may cancel it but this will also cancel your user ID and password, however you can always re-register. Two payment options are available. For corporate users, we simply bill you by fax for any model downloads. Payment is made by check posted to our Wilmington office or by bank wire transfer.
