While the web page still prompts users to enter an authorization code to continue, there is no working access code for Kreludan Mining Corp. The web page was used as a part of a previous Neopets plot and is no longer functional.
The Kreludan Mining Corp. page is a relic of a past Neopets plot. During the old Lost Desert plot, the access code was available from the Fortune Teller. After the plot ended, the numbers ceased being available and it is not possible to progress into the mine.
However, there is an unrelated Neopets game with the same name available in website's game section.
