Under the terms of the agreement, MCFN will pay 14.7% of the actual capital cost of the East Tank Farm Development once the assets become operational, which is currently anticipated to be in the second quarter of 2017.

"We are very excited that MCFN has joined us as a partner in the East Tank Farm Development," said Mark Little, executive vice president, Upstream, Suncor. "We have worked closely with MCFN for many years and this type of joint venture partnership is an exciting next step for both of us. Not only will it provide the community with a long term revenue stream, it recognizes the value of relationships, building mutual trust and respect and strengthening the participation of Aboriginal Peoples in energy development."

MCFN's 14.7% share of the actual capital cost of the East Tank Farm Development is currently anticipated to be approximately $147 million which will be payable to Suncor upon closing. The transaction is subject to a number of closing conditions including the negotiation of definitive documentation, the First Nation obtaining suitable financing, due diligence and other conditions customary for transactions of this nature and is anticipated to close in the second quarter of 2017.

Revenue from the long-term terminaling services agreements with the Fort Hills partners will underpin MCFN's independent financing of the transaction. Suncor will be the operator of the East Tank Farm Development once operational.

"The signing of this agreement has great significance for our people. It means long-term financial stability and increased independence while helping ensure future generations of our community remain a partner in regional development," said Chief Steve Courtoreille, MCFN. "We are very pleased to be working together with our partners at Suncor in this business opportunity."

MCFN's equity interest is in addition to the 34.3% equity interest announced in September by Suncor and Fort McKay First Nation. The combined equity interest by Fort McKay First Nation and MCFN in Suncor's East Tank Farm Development is 49%.

The East Tank Farm Development is a Suncor-operated midstream asset currently under construction in the Wood Buffalo Region of Alberta. The facility will consist of bitumen storage, blending and cooling facilities and connectivity to third party pipelines.

Mikisew Cree First Nation (MCFN) MCFN signed Treaty 8 in 1899. The Mikisew Cree have resided in Northeastern Alberta since time immemorial. We have lived a traditional lifestyle that included close understanding of the natural way of life. Even today most of our members in Fort Chipewyan rely on "country foods" such as fish, birds, and moose for a significant portion of our diet, and many of our members continue to enjoy a lifestyle featuring travel and time spent on the land. Athabasca Delta, which is in the centre of our traditional lands, is a unique international ecosystem which we cherish. It is the source of much that sustains us. When the fur trade came west and established a trading fort in this area, the Mikisew Cree were among those who traded furs.

The traditional lands of the MCFN range over much of the area where the Athabasca Oil Sands deposits have been found. MCFN shares this territory with four other First Nations that make up the Athabasca Tribal Council. At the present time most members reside in Fort McMurray, Edmonton, Fort Smith, NWT and Fort Chipewyan. Our Nation has the largest population of the five Athabasca Tribal Council Nations. In 1986, we signed a Treaty Land Entitlement with Canada that created several reserves in and around the Fort Chipewyan area and into the area north of Lake Athabasca and in 2005 we were able to win a legal case at the Supreme Court of Canada affirming our rights and title interests to areas of the Wood Buffalo National Park. We are today working out the details of our relationship with the National Park administration. We continue to press for our rights for the Agricultural Benefits from Treaty 8, and we are in the process of settling the long outstanding remaining "unfinished business" from our 1986 Treaty Land Entitlement settlement. MCFN is proud of our heritage, and confident in its bright future.
