RE:RE:RE:RE:RE:RE:RE:option done!Thanks guys fot your input, I also "just" received an official answer from the company for the same question:
There is no question that the river will have to be diverted in order to maximize the mine plan for Santo Tomas. Once we have more drilling data from the North Zone, we will identify the best diversion strategy for the river. The choices are likely to be (a) a controlled spillway through an adit driven east to west underneath that area of the deposit that lies in between the North and South Zones, or (b) a cut in the shape of an arc through the Brasiles Zone which lies to the northeast of the North Zone on the north side of the river. From an engineering perspective, either solution is relatively straight forward. Other than the capital cost, which is yet to be calculated, the main issue will be environmental compliance. The river is currently controlled by the Huites Dam, which is about 20km downstream, for agricultural and power generation purposes. We anticipate that the potential magnitude of the Santo Tomas project and the positive consequences that will be derived for the local communities will assist us in developing a diversion plan that will not create any long term adverse conditions for the waterway. However, it is an important aspect of the project development plan that will have a significant impact on the scope of the project.
I hope that this reasonably summarizes the situation.
