Hope you know how to use a gold pan. Someone told me I didn't know what I was talking about. I was taught how to gold pan 65 years ago. The man was panning all his life. He was about 70 at the time. I was sitting next to a ball mill with two prospectors 15 years ago. They did it the same as I did. Point is plastic pans were never used. Large metal if you can find one. Burn it blue-black to start. Store with light oil, never use vegetable oil. If you use oil burn off next time out.
