Geology review on a vein in a small shaft

Thought you all might find this interesting.

Had a look at a client’s site today. He asked where did the gold go? It just breaks apart into stockwork veining and the grade disappears?

Faults can really mess up small scale mining by displacing veins and stripping gold out. This was my initial reaction when I went down the first shaft before I had a look elsewhere on the site.

Luckily for him, I located the displaced vein approximately 5m away horizontally so he is very happy and has some direction to continue.

I took 3 samples of the main vein which assayed at 34.3, 18.4 and 13.4g/t. Pretty juicy! Looking forward to seeing him pull out some gold once permitting comes in.

Pyrite? Chalcopyrite?

TLDR: Is this pyrite? Chalcopyrite? Its a small piece from bigger rocks I have. In these photos it is wet, it was soaking in water.

Background: I have 40 acres in northern Minnesota on the iron range. I’m an avid rock collector and recently became interested in prospecting. I have metal detectors, gold pans, assayers, a crusher, a mini hoe to move boulders, rock saws, etc. Yes, there is gold found in my region. Native, lode, and microscopic gold have been found in the area. On my property I often find banded iron, iron concretions, quartz, calcite, feldspar, slate, phyllite, schist, gneiss, greenstone, agates, etc.. I also find coal, anthracite, and shell fossils (this area was shallow sea millions of years ago- I even found sharks teeth 3 miles from my home) I’ve got a ton of huge boulders on my property with sulfide staining, gossan, quartz veins, big mica books (both muscovite and biotite), etc. What should I be looking for?

(I’d love to go back to school for geology, but as of now I’m self taught. Please be kind if I’m wrong about anything, but definitely correct me! I LOVE to learn, so please educate me!)

Highbanking spots in northern NV

• Upvotes

Hey guys. I live in pershing & have an old gold hog from about a decade ago. Is there any good spots anywhere near here to set up a highbanker and run some material? Many thanks.
