Cautionary Note concerning Historical Resources
Threegold has not verified the classification of the Standard Gold Property resource under National Instrument 43-101 and therefore the above-quoted figures are reported as an unclassified historical resource estimate. Resource estimates prepared under reporting codes other than National Instrument 43-101 should not be relied upon to conform to current standards and definitions. Furthermore, readers are cautioned that mineral resources are not economic mineral reserves and that the economic viability of resources has not been demonstrated. Historical unclassified resources are considered too geologically speculative to have any economic considerations applied to them. It cannot be assumed that all or any part of a historical mineral resource will ever be upgraded to a higher NI43-101 category.
