Dr. Joe Champion left a simple, step-by-step method that he claimed could produce gold from silver using “mutant” yeast.

Mutant Yeast ---
Making Gold
Prior to starting, I warn you that you that the probability is you may fail. I am not being negative, but realistic. To understand this more, please visit this page. It will cost you some money to get through the first step to see if you have the abilities to achieve the first level. Millions of dollars and brilliant people have attempted this process and I know of only two people who have reached near commercial production. If you attempt it, I wish you total success. However if you fail, please accept the risks for your money and time. To my knowledge there is no danger in this procedure or I would not be doing it...
Requirements include the following:
I bucket similar to a 5 gallon bucket purchased at a hardware store
10 to 15 ounces of silver shot which can be ordered from any jewelry store.
One gallon of distilled water
One kilogram of yeast [Preferred Fleischmann’s yeast]
Place the silver yeast and water in the bucket and place the bucket in a area that is warm. I use the sun as my heater but sunlight is not required.
The preferred temperature is near 100 degrees but the process will work at lower temperatures but is slower. Try to stir the bucket at least three times a day. During the first two days you may see the yeast rise. Just stir in back into the water. It will take between four and seven days for you to start seeing the first gold color on top of your silver shot. Depending on conditions it may take upwards to twenty days...
