Test results obtained by us for certain portions of our properties and concentrates by independent
assayers may prove inaccurate for all or any portion of a property or some concentrates.
We have relied primarily on independent assays to determine that the Skull Valley
Concentrates have value. The independent assays were based on samplings and certain assumptions
as to the size, formation and concentration of an ore body. While assays are used to calculate a
reasonable indication of probable precious metal content, their accuracy is not guaranteed. Sampled
metals, regardless of how frequently spaced within a resource, may not be representative of the entire
inventory. If any assumptions related to the assays on which we rely, or out internal analyses, are
inaccurate, estimates as to the value of metals in which we have an interest, such as the value of the
Skull Valley Concentrates, may prove to be inaccurate. Since our business plan and the value of our
company is based to a large extent on our estimated value of the Skull Valley Concentrates, any
significant errors in such estimates would change the value of our company and the amount of any
potential future revenues.
