(All amounts expressed in US dollars unless otherwise indicated)

TORONTO, June 25, 2012 /CNW/ - Royal Nickel Corporation ("RNC") (TSX: RNX) is pleased to announce, further to its news release of May 14, 2012, that the full Dumont Nickel Project ("Dumont") NI 43-101 compliant technical report ("revised PFS") has been filed under RNC's profile on SEDAR at www.sedar.com and on RNC's website at www.royalnickel.com.

A stated key focus for RNC in 2012 is to advance its goal of securing a project partner for the development of Dumont. With the completion of the revised PFS and following several months of informal discussions, RNC has now entered the formal phase of the partner process during which formal discussions with interested parties will take place and prospective partners will be invited to submit proposals. RNC's financial advisor for the Dumont project, Rothschild (see RNC news release dated January 18, 2012), will play a key role in the partner process and the contemplated project financing for Dumont.

"The full revised PFS is now complete and the hard work continues as our team has turned its full attention to key near-to-mid-term milestones such as the project partnership and finance process and advancing the feasibility study, which is already underway," said Tyler Mitchelson, President and CEO of RNC.

The previously announced highlights from the revised PFS (base case including trolley assist option) compared to the previous PFS filed on SEDAR in December 2011 include:

• 31% increase in after-tax NPV_8% to $1.4 billion; 19.5% after-tax internal rate of return ("IRR")¹
• 16% increase in the initial 50 ktpd nickel production to 33 kt (72 million pounds or Mlbs) annually
• 12% increase in production to 49 kt (108 Mlbs) annually during 19-year mine life; and a 7% increase in production to 29 kt (63 Mlbs) annually for the subsequent 12 years from processing of the lower grade stockpile
• 10% increase in recoveries over life of the project to 45%; including an average recovery of 52% during the 19-year mine life
• C1 cash costs² of $4.07 per pound ($8,973 per tonne), second quartile unit cash costs
• Diesel consumption reduced by 28% through use of electric trolley assist in haul trucks
