Gold Exploration Company Development... Need Suggestions.

I'm working with a gold company in expanding operations and developing the company further. We're actively looking for new investors to invest. Not in gold, but in the actual exploration of gold. The company dig site has shown, based on 3rd party verification through NI 43-101, that it can produce about 2 ounces of gold per tonne with and estimated 5 million ounces of gold on only 100 acres of the company's 1200+ acres. The return would be about 85% for the current year and 171% for the following years.

I need suggestions on how to find some solid investors. Any way of doing so other than advertising or cold calling? I'd prefer not to do either, especially since this is a solid proven and established company that is looking for qualified and verified investors with a minimum net worth.

Any ideas or suggestions would be much appreciated!
