Estimates of mineralization and other technical information included herein have been prepared

in accordance with N I 43-101. The definitions of proven and probable reserves used in NI 43 -

101 differ from the definitions in SEC Industry Guide 7. Under S EC Industry Guide 7 standards,

mineralization may not be classified as a “reserve” unless the mineralization can be economically

and legally extracted or produced at the time the “reserve” determination is made. As a result,

the reserves reported by the Co mpany in accordance with NI 43 -101 may not qualify as

“reserves” under SEC Industry Guide 7. In addition, the terms “mineral resource” , “measured

mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in

and required to be disclosed by NI 43 -101; however, these terms are not defined terms under

SEC Industry Guide 7 and historically have not been permitted to be used in reports and

registration statements filed with the SEC pursuant to SEC Industry Guide 7. Mineral resour ces

that are not mineral reserves do not have demonstrated economic viability. Investors are

cautioned not to assume that any part or all of the mineral deposits in these categories will ever

be converted into reserves. In particular, “inferred mineral res ources” have a great amount of

uncertainty as to their existence and great uncertainty as to their economic and legal feasibility.

It cannot be assumed that all or any part of an “inferred mineral resource” will ever be upgraded

to a higher category. Discl osure of “contained ounces” in a resource is permitted disclosure

under NI 43 -101; however , SEC Industry Guide 7 normally only permits issuers to report

mineralization that does not constitute “reserves” by SEC Industry Guide 7 standards as in-place

tonnage and grade without reference to unit measures. Accordingly, descriptions of the

Company’s mineral deposits in this press release may not be comparable to similar information

made public by U.S. companies subject to the reporting and disclosure requirements of SEC

Industry Guide 7.
