On March 7, 2013, Denison's Board of Directors approved an amendment to the Company's by-laws which is subject to shareholder confirmation at the Company's annual and special meeting of shareholders on May 9, 2013. The amendment sets a deadline by which shareholders must submit a notice of director nominations to the Company prior to any annual or special meeting of shareholders where directors are to be elected and also sets out information which a shareholder must include in that notice. In the case of an annual meeting of shareholders, notice to the Company must be provided not less than 30 days prior to the date of the meeting. For this year's meeting, any notice of director nominations must be delivered to the Company prior to the close of business on Tuesday, April 9, 2013. The amended by-laws are available on the Company's profile on SEDAR at www.sedar.com and will be described in detail in the Company's management information circular to be mailed to shareholders in early April.

Outlook for 2013

Canada

Exploration

Denison will manage or participate in 11 exploration programs, of which Wheeler River will continue to be the primary focus. In addition to the Wheeler River project (25,000 metres), winter drill programs are also planned for Moore Lake (6,400 metres), Hatchet Lake (1,940 metres), Wolly (2,500 metres) and McClean Lake (4,000 metres). Wolly and McClean Lake are operated by ARC and Denison's interest is 22.5% in each of those projects. Exploration work including drilling or geophysical programs will also be carried out on the Crawford, Bachman, Russell Lake, Stevenson River, Perpete Lake and Bell Lake properties. The total budget for these programs is CAD$14,600,000, of which Denison's share is CAD$9,900,000.

Development / Operations

Denison and its partners have budgeted CAD$3,500,000 (Denison's share CAD$814,000) to be spent on the SABRE program as well as the Midwest and McClean Underground development stage projects in 2013. The majority of the expenditures are planned for the evaluation of the results of the SABRE two hole test program, completed in 2012, and the preliminary evaluation of the SABRE mining method for the Caribou and Midwest deposits. The McClean Underground project Feasibility Study was completed in the fourth quarter of 2012, and it was agreed to postpone a production decision due to the poor condition of the uranium market. A production decision will be revisited in 2013. Very little work is currently planned on the Midwest project.

The McClean Lake mill continues to be on stand-by, but activity at the mill has begun to ramp up in preparation for processing of Cigar Lake ore anticipated to begin later in 2013. Construction on the McClean Lake mill expansion, which is 100% funded by the Cigar Lake Joint Venture, began last summer and will increase annual production capacity to 24 million pounds U3O8. Denison's share of operating and capital expenditures in 2013 is estimated at CAD$1,800,000. Denison expenditures are expected to be offset by revenue projected at CAD$1,500,000 from toll milling revenues and the proceeds from the sale of approximately 25,000 pounds U3O8 recovered from McClean Lake ores processed as part of the Cigar Lake commissioning efforts.

International

On its wholly owned Mutanga project in Zambia, the Company plans to carry out extensive programs of geological mapping and geochemical and geophysical surveying to increase the confidence in existing drill targets and identify new targets. At this point no exploration drilling is planned for 2013. The Zambian program will total an estimated $3,500,000.
