Hello, I wanted to share this object I found and get peoples thoughts on it. It was found while gold dredging this summer in the North Central Cascades, Washington State, USA. It appears to me to be a micro engraved artifact of unknown origin. It measures approx. 4.1mm x 3.1mm and is .49mm thick. It appears to be copper coated gold with a precision micro engraved repeating pattern etched into the surface.

Other objects that appeared to be VERY old electronic components have also been collected from the area in the past but were stolen from my collection. I’d love to hear from people who know more about these things, Thanks.
(The collection site is in the mountains 22+ miles from the nearest town)
