There are many ways to invest, but here are some you may want to think about:
1) Buy physical gold and store it with a reputable dealer 2) Mining producers - companies that have already found gold and are producing it 3) Mining explorers - companies that are not yet producing. These vary enormously, some have found some gold and are looking to take it into production, whilst others have found nothing economical. 4) ETF's - these provide different exposure to the market. You need to clearly understand what you are investing in.
I'd suggest you speak with your professional financial advisor before making any investment in this market.
