Not the first time having rocks ring up . Usually it's slag however this rock is different
silver ore Appreciate and feedback. Just looked at it under my loop it has black crystal on one side
I take all my "hot rocks" and put them into a bucket until the bucket is full.
Once the bucket is full I break the rocks in half to see which side is still hot while discarding the parts that are not. I repeat the steps until finding something in the rock or discarding the waste.
I run my detector over the waste, and if it detects something I separate half into another bucket and repeat the steps until I find something or simply learn the rocks won this time against me...lol.
