They are in the sand business not rocks. So with that, the gold will settle in these rocks and travel on down to bedrock.
Often wondered hearing two different opinions:
- Gold is heavy and will on its own drill down through soil / cobble / rocks to bedrock.
- Gold in a mix of material will remain stationary until disturbed. ie. a flow of water needs to suspend / stratify the material for gold to settle out lower
Which one of these is true?
If I put some nuggets on the top of a pail of dirt I should be able to leave them in the garage and some time later (long time) they will reach the bottom of the pail?
Edit: Just thought of another aspect of the settling thought:
Rarely see flour gold vs larger gold regarding settling discussed. Also heard two different theories here.
- Flour gold is so small relative to the cobbles/rocks/sand mix that it typically remains mixed in with the sand. Some of it will settle out during flow through water but for the most part it is light enough it does not settle and concentrate like larger particles.
- All gold is so heavy that it will settle out to bedrock or false bedrock
When prospecting is there a different model to consider for flour gold vs larger gold. They both share common properties and behavior but I get the sense that flour gold behaves differently vs larger gold in terms of transport / settling / concentration?
