Here are the inaccuracies (paraphrased) in the The Northern News Services (see below) that Dave Webb communicated to me today:

In the sentence is inaccurate,“….Tyhee Development Corp. is beginning work on a pre-feasibility study for the future mine located 90 km north of Yellowknife.” Tyhee is, in fact, advancing towards production, and much of what is now being done are components of, or are required for a prefeasibility or feasibility study.

In the fifth, sixth etc. paragraphs one is led to believe Tyhee would complete a prefeasibility and then move on to a feasibility study. In fact, when Tyhee’s current studies on the resource, engineering, environment, permitting etc., are completed, Tyhee may well decide to move straight to a Feasibility Study. (Note: The major difference between a PF and F study is the level of detail and what financers ask for.)

It is also worth noting that webb reminded me that there is no requirement to do one, both, or either to bring a mine into production and there is no hard and fast manual that describes what each study is, only what is “generally” described. Each and every aspect of the PA, PF and F studies contain words like “in the (geologist’s, engineer’s, metallurgist’s) opinion. These are quantitative studies with subjective determinations.
