Mr. Glenn Catchpole, President and Chief Executive Officer, acknowledged the significant contribution of Mr. Hartman: “George was the key person for Uranerz in the negotiation and acquisition of a number of Uranerz’ assets. He has led the Company’s exploration efforts and most recently construction of our Nichols Ranch ISR Uranium Project. On behalf of the Company’s Board and Management, I thank him for his dedication to Uranerz and wish him the very best in his retirement.”

Mr. Hartman commented: “I have found my time at Uranerz extremely rewarding as the Company has progressed from an early stage exploration company in 2005 to now, very near completion of construction of its first commercial ISR uranium mine. It has been of great personal satisfaction to me to assemble and train a new generation of uranium mining and exploration professionals that can competently guide Uranerz into production at Nichols Ranch.”
A succession plan is in place for each of the executive officers of the Company.

About Uranerz

Uranerz is a U.S. mining company focused on near-term commercial in-situ recovery (“ISR”) uranium production; the Company is currently constructing its first ISR mine in Wyoming. ISR is a mining process that uses a “leaching solution” to extract uranium from sandstone uranium deposits; it is the generally accepted extraction technology used in the Powder River Basin area of Wyoming (ISR comprised 45% of world uranium production in 2011). The Company controls a large strategic land position in the Pumpkin Buttes Uranium Mining District of the central Powder River Basin of Wyoming. Uranerz’ management team has specialized expertise in the ISR uranium mining method, and a record of licensing, constructing, and operating ISR uranium projects. The Company has entered into long-term uranium sales contracts for a portion of its planned production with Exelon and one other of the largest nuclear utilities in the country.
