Had another look at the Martha Gold mine, from what they are using today to extract the ore to what was used in the past is intresting, If you look real close (botterm left) you can see one of the old tunnels that the miner would have crawled through when it was still the underground mine.
With the open pit mining they would have used water for slucing to get the ore and then moved to blasting the rock ..
Old slucing machine and the new way, drilling holes for blasting
You can see the size with Gill standing beside one of the dump trucks that is on display
The sun is ment to shine thisweekend so all take care ...
