RE:I dont think this is what shareholders expected ! The NR only address two of the technical economic factors of the project. Just looking at alternative mine plans (a linear deposit mining instead of parallel pit construction if I understood correctly) and further metalluragy analysis to simplify the plant process flow.
The cost of fuel is a fairly minor factor for SPA.v because the site is so close to grid power (<10km) they won't require onsite generation. This avoids one of the large opex costs for a mine, but this will already be reflected in the existing PEA. The drop in $CAD will be a much larger (and very positive) impact on the project economics than fuel costs.
I interpret this NR as they are doing research on several technical topics, it's going well in the early stages of their analysis and the conclusion of these will determin if there is a material impact that would benifit and feed into the new PEA.
The updated PEA will include the current fuel, $CAD, POG, and updated process flow, throughput, mine plan, and LOM economics.
We'll know more in a couple months as to what they find and what comes next.
