"may not be achieved and cannot be relied upon"

Whats up with this wording?

I have been under the impression that the 2013 FS was sandbagged plus the dollar was at par at the time so we are WAY more profitable now.  Yes, metal prices are lower but the forecast of copper is generally held to be on its way up over the next few years.  I would expect the wording to be something along the lines of the 2013 FS is out of date and the economics of the project have greatly improved and should be considered with this data.

So what does this mean?
