Section 8 Other Events

Item 8.01

Uranerz Energy Corporation announces the staking of 222 additional federal mining claims in the area of the Pumpkin Buttes mining district of Wyoming’s Powder River basin. Uranerz selected prime areas it believes will contain oxidation-reduction geochemical (roll) fronts as well as uranium-mineralized areas not currently claimed by others. The staking is based on historic geological data, together with our exploration results from last year, as well as data obtained from recent drilling.

It is planned that these geochemical fronts and suspected mineralized areas will be drilled by placing drill hole fences perpendicular to the strike of the geochemical front to evaluate the strength of the intercepts. Once a series of wide spaced fences are complete and evaluation is finished, actual mineralization targets should be established and delineated.

Uranerz continues to research land availability in relation to suspected mineralization focusing on the Powder River Basin. Additional land acquisition is planned for the near future.
