Chapter 3 How to sample for hard rock gold and free mill gold!
In the last part I talked about where to find hard rock quartz that might contain gold. Ok you will need some basic tools to start a gold pan is a must, hammer, chisel, piece of thick plastic bag or similar plastic, good thick gloves, good pair of safety glasses, small shovel, and a screen 1/8 mess (stainless steel food strainers work great), and container or bucket. Ok next look at the quartz vein you have found, is there loose material laying at the bottom, if so great sampling will be easy. 1. If there is no loose material you will have to chip some off, do this in the most mineralized section of the vein you can find, be very careful to catch as much of the fine pieces that come off while you are taking your sample, (Do not breath any of the fine dust, hard rock ore can contain some dangerous minerals) you are trying to get enough crushed quartz material to pan a small sample bigger chunks should be check for visible gold and gold indicators sulfides, then can be wrapped in thick plastic placed on a hard surface and crushed up with a hammer to release more fine material, screen and pan this material and look very closely for very small pieces of free gold a magnifying glass can be very helpful to see micro gold. With this type of sampling, you will be lucky to see a couple tiny specs due to sample size you will be only test tiny amount of material, rock crushers will improve these tests by allowing large amount of sample material to be tested, I will be adding a post on the befits of rock crushers and sampling in the future.
2. You have material that has weathered out of the vein, this is good start by inspecting some of the material that is lying around for gold and sulfides ( sulfides are minerals like pyrite that indicate gold might be present in one of the pics you can the heavy amount of sulfides in the quartz) now try to gather some fine material and screen it down to 1/8 inch and pan this material to check for free mill gold and sulfides just because you don't find visible gold, the sulfides might have gold locked inside (future post will be on roasting sulfides to release gold. Also, when panning this type of material, you will be looking for micro gold, which is very hard to pan then add some sulfides some can be almost as heavy as the gold then it gets really tricky to pan. Learn to back pan, learn to tap the top of your pan to bring the gold up to top of your pan, and go slow take your time or the fine gold you do have might just get panned out and be gone and you will never know it was even there.
Next Chapter 4 will be on what to do when you find gold.
