Val-d’Or, Quebec, October 28, 2010 – Cartier Resources Inc. (TSX-V: ECR) (“Cartier”) is pleased to announce that it has signed a Letter of Intent (“LOI”) for its Rivière Doré property, located south-east of the town of Val-d’Or in the province of Quebec. Cartier has signed a binding LOI with Copper One Inc. (TSX-V: CUO) (“Copper One”), a corporation incorporated under the laws of British Columbia. Subject to customary conditions and a legal, technical and business due diligence, both parties have agreed to work towards signing a definitive agreement on or before January 15th 2011. The definitive agreement between Cartier and Copper One will be structured to optimize the exploration and development of the Rivière Doré copper project.

Under the terms of the LOI, Copper One is granted an Initial Option to acquire an undivided 51% interest in the Rivière Doré property by making cumulative exploration expenditures of $5,000,000 on or before December 31, 2015, including a firm first year commitment of $750,000 and paying $250,000 and issuing to Cartier 350,000 common shares of Copper One. Upon the valid exercise of the Initial Option, Copper One shall have an Additional Option to acquire a further 24% interest in the Rivière Doré property by continuing until the completion of a definitive feasibility study or making further cumulative expenditures of $20,000,000 by or before December 31, 2020.

The following schedule summarizes the terms of the LOI:

• Initial Option (to acquire 51%):
  • First Year (ending December 31st, 2011): a firm commitment for work expenditures of $750,000;
  • Years Two through Five (ending December 31, 2015); cumulative work expenditures of $5,000,000 (with expenditures being approximately $1,062,500 per year); and
  • Payment of $250,000 and issuance of 350,000 common shares of Copper One.

• Additional Option (to acquire 75%):
  • Completion of a definitive feasibility study; or
  • Years Six through Ten (ending December 31, 2020): cumulative work expenditures of $20,000,000 (with minimum expenditures of $1,000,000 in each year after December 31, 2015)

Cartier will manage the exploration program during the Initial Option period. After the first year of the Initial Option, Copper One may elect to operate the project. If it elects to do so, Copper One will make an annual cash payment to Cartier of $50,000 for each year that it shall operate the project during the Initial Option. The proposed agreement contemplates that a joint venture will be formed once Copper One has vested at 51% or 75%. The parties also agree that the definitive agreement will include negotiated terms for the joint venture agreement.

“Dealing with a company whose core business is copper provides the best opportunity for success on Rivière Doré,” commented Philippe Cloutier, President and CEO of Cartier. “We are very pleased with the design of this agreement as our partner’s investment is focused towards expanding on the 2009 surface discoveries and explore numerous other targets on the property.”
