Iron Rock detected with MXT and SST?

[Featherdfishead]

Hello everyone,
My Gold Bug Pro arrives tomorrow !!!

Got a question, my buddy's been detecting about 9 yrs and just the other day we were detecting and digging around an old open pit copper mine. As i'm chunking off some beautiful malachite and azurite rocks and were bs'n, jimmy says I never have found a rock that read iron, negative or neutral. About ten minutes later were both detecting just 10ft from the pit when I hit a two fist sized rock that hit as iron. I was using a Whites SST and jimmy an MXT. Sadly we left the roc k in a pile went ment to bring home but didn't. No biggy really not many people go to the old mine so they'll likely be their. Curious to test it on my GBP.
Any Ideas?
Thanks, Happy Days - Happy Hunting!
Adam

If it has enough iron content in it, that's very possible.

Did you test it with a super-magnet to see how that test turned out? Often, that's a good, quick test for iron content.

All the best,

Didn't test with magnet but will. I figured that iron rocks would detect as so and was surprised to hear that my buddy hadn't came across them. I 've detected with him on and off for the last 6 yrs or so but am new with my own machine and that day brought up the topic because I walk rivers in my work and know iron rocks that are fist sized that are some of the heaviest rocks Iv ever seen.

When I did surface suction mining, and I'd come across big chunks of heavily iron-impregnated rock, I knew I'd soon be seeing visible gold in the seam. Big chunks were a great sign that I was in an area where the super-heavies had dropped out, and any gold running with them would drop out too.

Yes, some iron-rich rocks are fist-sized, and some can be much bigger too.

Big chunks of iron-rich meteorite fit into that category as well.

All the best,

Lanny
