The Snapshot

Once all the numbers from all the samples and water tests are compiled, a snapshot of the performance of each tank in the process circuit can be seen side-by-side.
Regarding "Good Assays and Bad"
Last month I wrote an article entitled “Good Assays and Bad,” which gathered a few comments.
Pumping Water With Solar Power
Solar energy can be used for any size placer or hard rock mining operation. It is most practical for small and longer-term operations provided your mine is not located in a dense forest.
How to Interpret Assay Values
This assay system of ounces per ton sounds simple enough, but the use of the metric system and the additional measuring terms of “grams per ton” and “parts per million” (ppm) has created some misunderstanding of ore value.
How Long Does It Take to Find and Recover An Ounce of Gold?
Some ask if a prospector can collect an entire ounce in a day. It is possible; I’ve done it before.
Proper Spacing of Placer Sample Sites
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
