The company noted that it will have an opportunity to acquire all the shares by way of a compulsory acquisition, if it is successful in acquiring 90% of the Rockgate common shares.
Denison president and CEO Ron Hochstein said the company has received good support from Rockgate shareholders.
"We encourage any Rockgate shareholders who have not yet accepted the offer to do so as soon as possible to enable Denison to proceed to compulsory acquisition," Hochstein added.
Denison is a uranium exploration and development company, which has interests in exploration and development projects in Canada, Zambia, Namibia, and Mongolia.
The company’s project portfolio includes 49 projects and totals around 597,000 hectares in the Eastern Athabasca Basin region of Saskatchewan, with 22.5% ownership interest in the McClean Lake joint venture that covers several uranium deposits and the McClean Lake uranium mill.
