The future of Egina?…

Hmmm. And what if the gold bearing layer is between 3 ft and 6 ft deep gc?
Dats da thing. How to remove without deeluve

Hello Venetian Open Heart Miner,
According to Q the overburden is only 20 cm thick and the gravel in the swale is unconsolidated and just sort of 3-4 m deep.
Do you think these scrapers in the videos could be cost effective and up to the excavation task (one piece of equipment instead of two) or do you think it would be more efficient with shovels and dump trucks…or?
Love to hear your opinion V, much appreciated.

Scrapers are for scraping, not for load and hauling. If the material is loose enough the most efficient would be front end loading. If not then shovels. Loaders are faster and they make for a more level floor also. If the overburden is only 20 cm and the pay is 3 to 4 meters then it will probably all be picked up and put through the system. Trying to seperate ore from waste will result in a stew anyways.

Thanks V-Stud.
What do you (or anyone else) think about processing the Egina terrace gravels?
I picture splitting the gravel into four streams...
1) Sand and fines
2) Small gravel up to say 25mm (whatever the optimal size range for eddy current is)
3) Larger gravel up to 100 or 125mm (optimal size for the Tomra sorter)
4) Larger rocks would be crushed or waste depending on the value of that stream.
The sand is waste (Q), the small gravel would go to the eddy current non-ferrous metal separator, and the larger gravel could go through the Tomra. Waste sand and rock could be re-mixed with tailings pre backfill.
Excavate, separate, sort, remix, backfill, rehab.
Just a picture.
