...what also leads me to this Round Lake theory, look at the high resolution image of the Ross Pluton eruption. The centre of the Ross eye sits on the 1/3 third side of the slide under the 320000e vertical line. I am not sure an the scale given with the slide so i only speculate here on distance but i have compared to Sans magnetic image for distance. I think as you move West ( left ) on the centre of the slide follow the green line mark RL. You will notice two exits from the Pluton with the top exit a possible sources onto the greens and the bottom left exit a possible source of the main mine structure as we can see alot of magnetic structure. In the centre of the slide under 300000e and just above the centre you will notice a bunch of structures sitting in a East West direction and this is possibly sitting under Round Lake.
