Daily price fluctuations, or even on a weekly basis, have little to do with us because we are not producing nor are we close to.
At this moment in time we are concerned with the size of the resource and it's quality ( concentration ) thus determining it's economics of production. The metal prices being merely an exercise as to the value in ground as an aid to guesstimating what the share price could or should be.
The metal prices will be of real interest about two to five years from now, when we first apply for financing of mine for construction ( in-ground resources as collateral ) and later once we start producing ( i.e. profits start coming in).
The short version of the above is - Metal prices have little or no effect on our share price - Now.
