There now are hundreds (maybe thousands!) of questions from Gold Rush game players that are posted in the Yahoo Answers system. The answers to the questions are provided by other users and contain a lot of clues, solutions and hints. When you go to their site, type in the keywords in the "Search for questions" box. I tried these keywords "Gold Rush" and got lot's of hits. To narrow the search try using the keywords "Gold Rush Round 5", or any other Round # for which you need hints / clues or answers.
