That's how all the 925 silvers come out of the ground here. Something to do with mineralization, lots of sulfides I reckon, and quite annoying! The tag has got 1ton 1951-52 stamped on it. Was an apple orchard years ago so assuming it was off a crate of apples. My mate found a few stencils of weights and numbers cut out of copper sheets too. Only got through the immediate yard area so will have to head back to check out the paddocks and creek soon.
