So many unknowns at that early stage that Micon keeps referring to.

"Given the early stage of the project’s development, no detailed information is available in respect of operating costs for mining, processing and general and administration in respect of a potential open pit mining operation. As well, no geotechnical information is available upon which to estimate an overall slope angle. Consequently, Micon derived estimates for these items on the basis of its experience in the region and from general knowledge. It is to be noted that the estimates presented are only for the purpose of developing an initial optimized open pit shell, and the assumed values will likely change with further detailed work."
