Investors are also cautioned that while National Instrument 43-101 and subpart 1300 of SEC Regulation S-K recognize measured mineral resources , indicated mineral resources and inferred mineral resources , investors should not assume that any part or all of the mineral deposits in these categories will ever be converted into a higher category of mineral resources or into mineral reserves.

Further, inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. In accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under National Instrument 43-101.
