Any one tell me what this is? I weighted the rock before I crushed it and it was 8.2 oz a rock the same size that looked to be granite was 3.4 oz. it's not magnetic and has a specific gravity very similar to lead. It reacts with nitric acid but does not change colors. I'm totally stumped. It came from a tailings pile of a 3 metals mine. Helps please.

Bornite (peacock ore) looks like.

Im not sure that its bornite because its to heavy to have a SG of 5.6. from the best I can tell its SG is somewhere around 11-12

Here are two interesting examples of the quartz that I've been finding around central Minnesota. I've been interested in gold for a few years now and looked a a Gazillion google images. There i an old iron range where i'm from, the pits are all lakes now, but they report finding some, not a lot but some gold, along with lots of iron, copper, manganese, etc. I'm glad I ran into your thread I hope you can tell me about the stuff I've been coming across. Thank you.

Great forum! lots of good intimation. Soaked some pieces in muriatic acid for a few days.. Half debating on saving it instead of crushing. Think it's anything good? Or crush it up and pan?

Painite ?

I'm at work right now but I'll watch the video as soon as I'm on lunch. I ended up taking a smaller piece and crushed it. Had some great interesting things in the bottom of the pan, I'll post a pic this evening

I recently bought my first mining claim and picked up a few buckets of material to test and figure out where to search. The problem is that I don't really know exactly what I'm looking for yet. I've panned a little gold previously and collected rocks but I don't know much about them. I was referred to this website and it looks like I found the right place for mineral hunting! I think this rock may be silver ore but I'm not sure. Thanks for your help!

I have this Rock that is a shiny silver/gray color with the orange color around the edges. It is very heavy, non magnetic and is about the size of my two hands cupped together. I did a silver test on it using nitric acid and muriatic acid. It came in a bottle I bought online. I found this Rock in Chickasha, Oklahoma just outside by my house. When I did the silver test, I scratched off some of the Rock and put the drop of acid on it. It bubbled and the shavings turned gray. I just want to know what this Rock is. Can you help me figure this out?

I'm new to the site so if I go about things the wrong way I apologize. I recently began hunting for geodes and I'm hooked let me tell you!! I have found several very interesting pieces in the past two days. This one I found in a stream near my house. I chose to post it because it's easiest to see the detail without a magnifying glass. The others are difficult to capture the details in photographs
