Great to see a real mine in operation,have enjoyed all your posts.Can't waite till you hit the high-grade reef. Have you figured out a concentration table for your mill yet? Thanks for the picks. Chuck

I picked up the bogger for $1500 and it cost me $500 in transport costs to get it from Broken Hill, they run on air, Im using a 190cfm compressor and it runs it easily.
The reef at the face is looking promising, Im going to start building a shaker table shortly thats going to be a cross between a Wilfley and a Gemini. Ive been working on the design and I think Ive got it all sorted, when Im finished Ill post the plans.
Im also going to make a few more videos of drilling and blasting etc to post.
How are you going with your mine Kid , you putting a bit of that reef through your mill?

That's a cool video!!! Thanks for sharing. What is the host rock made up of? That's a mighty smooth hanging wall

 

[centennial]

Host rock is Devonian sandstone, siltstones and shale, these beds were lay down in a shallow sea on the coast of Gondwana about 360 million years ago, along the coast at that time was a large string of volcanoes above a subduction zone (The Baldwin Volcanic Arc ).
During the Permian about 260 million years ago the volcanic chain had eroded away and compression in the area uplifted, folded and faulted these sediments.
During the Cretaceous about 60 million years ago , further volcanic activity in the area forced mineralised fluids into the fractures and faults in the tops of these folds (anticlines)and eruptions brought with them rubys which had formed about 20 km deep and are now in some of the creeks.
About 45 million years ago Australia broke away from Gondwana and started drifting north.
About 140 years ago two timber cutters found gold in the creeks and soon prospectors found the mineralised fractures (reefs).
Its a long story.
Heres some of the rubys from the area
