Lost mines have been using under water drones for some time now. Absolutely awesome video footage that they have done, mine carts hidden from veiw for umpteen years. Inaccessible tunnels and drifts. Great to see you using technology to explore sections of the mines not accessible normally, looking forward to some great video footage fella.
Ay up me duck. Nice one buddy, look forward to seeing some great underwater footage in the future but please, no more of Richie with his shirt off, lol. 👍🙂
