Placer Deposit Grade

When it comes to grade, one that ranges from thirty to around one hundred feet per mile will help the deposition of gold. In places where the grade is over that, like in the streams of the mountains or in narrow canyons, will not be a very good source of placer deposits. After a stream has left its mountain canyons and goes into a flatter country or in a body of still water, the materials that are moved along by the stream are embedded in the form of a fan or a delta. At the top of this fat the fine gold becomes deposited and might never get to the bedrock. The movement that takes place in the harsh mountains during flooding season, which lets gold get to the bedrock, does not occur in the delta. To close, keep in mind that gold weighs more than other material that is found in the stream bed, and that it will fall anywhere the flow or grade alters, making the stream to reduce in speed and lose its power to carry; these are specifically the type of places prospectors will want to look into. Every time there is a rainy season you can be assured that at least some gold is coming down from the hills and into the stream beds. Remember also that the early miners used to work in deposits that had time to develop for thousands of years, whereas now we this is different. Go after the material that has not been worked on and try to get to the difficult places to reach where the gravels have not been worked on as much.
