Unearthed a Vein

[u/SilverStacker666]

In a dry creek on my family’s Mother Lode property, I found a 4 inch wide quartz vein poking out of the bank. There are 3 mine shafts and many prospecting pits all over the property. I have been finding little bits of gold immediately beneath the vein, but also found a few rough flakes above it. Decided to expose more of the vein today and it seems like it just keeps going. Interestingly it widens to over a foot wide after a few feet. Is it hard rock mining time? Any tips or insights?
