Webgogs - Any hints where/how Capex costs can be saved or insulated from inflation? Conveyor?

The most interesting to me is the expansion of the main deposits and how they are creeping back into Mt LaCasse. As the new (TBA) mine rim moves out to the north and NE the steep 1.2km high pit wall on the NE corner becomes increasingly lower as you move into the mountain. For a while, each 1m of extention of this part of the mine means about 2 m lower pit wall elevation. This isn't really a Capex item, but a potential OPEX cost saving.
