SOLG MRE, page-7

Which way do you think this resource will be mined? Most of the resource found is located many hundreds of metres under the surface....taking that there is 700-1000 metres of resource there. Open cut will be a huge undertaking knowing the diameters (width, length and depth) involved and what do they do with that overburden? Huge project in the middle of mountainous, undeveloped forest and jungle.

There is also some conjecture that access to /mining of resource will be undertaken from the side by tunneling. As a mining technique I would have thought this would severely limit how much one could extract.....limited to height and walls to hold up the ceiling, etc. 1000 metres of found resource depth would be limited to carving out layer - gap - layer - gap and so forth, and therefore could it be expected actual extraction might be limited, i.e., to say one tenth of 1 billion tonnes????????? No use celebrating 1 billion tonnes as a MRE if one can only mine and extract a small percentage of it.

Obviously the less dirt to be extracted before reaching the desired resource being mined the better...so how does this compare to all the other copper/gold resources located in near areas of South America and around the world? It won't matter how good the surrounding infrastructure advantages are, e.g., access to road, water, workers, rail and power, etc., if at the end of the day, the mining technique that can be used is not environmentally and economically sound and the project is ultimately not sustainable.
