Lundin Mining Announces Agreement to Acquire Interest in High Grade Copper/Gold Project from Freeport

TORONTO, ONTARIO--(Marketwired - Mar 3, 2016) - Lundin Mining Corporation (TSX:LUN) (OMX:LUMI) ("Lundin Mining", "Lundin" or the "Company") is pleased to announce that it has entered into a purchase agreement with an affiliate of Freeport-McMoRan Inc. ("Freeport") to purchase an interest in Freeport's stake in the Timok project located in Serbia. The high grade copper-gold Cukaru Peki deposit is situated on one of the four mineral licenses comprising the Timok project. The project partners are currently Freeport, who is operator of the project, and an affiliate of Reservoir Minerals Inc. ("Reservoir") which holds a minority stake in the project and has certain transfer rights as a result of the proposed transaction.

Total consideration of up to US$262,500,000 is payable in stages upon the achievement of key development milestones defined under the purchase agreement, as more particularly described below.

The transaction is subject to Reservoir's right of first offer ("ROFO"), as well as other customary closing conditions. Prior to entry into the purchase agreement, a ROFO notice was provided today by Freeport to Reservoir, and is open for acceptance by Reservoir for 60 days from the receipt of notice. If the ROFO is not exercised by Reservoir, the transaction is expected to close in the second quarter of 2016.

Mr. Paul Conibear, President and CEO commented, "The acquisition of an interest in the Timok project is consistent with our growth criteria that we have rigorously followed over the last few years. This high quality copper/gold project fits ideally within our overall asset base of operations in the Americas and Europe. This transaction enables the existing Freeport/Reservoir partnership to leverage our proven underground base metals development, construction and operating skill sets to advance the Timok project into operation in a timely manner. The Timok project is expected to enhance the Company's long term copper growth pipeline, while preserving our strong balance sheet. We are very pleased to be able to extend our partnership with Freeport and we intend to advance a meaningful and cooperative relationship with Reservoir to the benefit of all stakeholders including those in Serbia."

Transaction Terms

Under the purchase agreement, and subject to Reservoir's ROFO, Lundin will acquire (1) 100% of Freeport's interest in the upper zone of the Cukaru Peki deposit which is characterized by high grade massive and semi-massive sulphide mineralization (the "Upper Zone"), as well as Freeport's interest in all the mineral licenses comprising the Timok project, and (2) 28% of Freeport's interest in the lower zone of the Cukaru Peki deposit which is characterized by porphyry-style mineralization (the "Lower Zone"). Freeport will retain the remaining interest in the Lower Zone. In addition, Freeport has the option to have any new large mineral deposit containing at least four million tonnes of contained copper equivalent characterized in the same manner as the Lower Zone upon the payment to Lundin of two times drilling, study and other similar costs plus other direct costs such as land acquisition costs.

As part of the transaction, Lundin will be appointed as operator of the Timok project until the occurrence of certain events and Lundin will advance the development of both the Upper Zone and the Lower Zone in accordance with approved budgets and work programs. Lundin will have the sole right to propose budgets and work programs relating to the Upper Zone and for certain agreed Lower Zone work, and Freeport will have the sole right to propose budgets and work programs relating to the Lower Zone, subject to specified exceptions.

Until the delivery of a feasibility study Lundin will fund 100% of the Upper Zone development costs, as well as $20 million of agreed Lower Zone work, and Lundin and Freeport will fund 28% and 72% of all other Lower Zone development costs, respectively. After the delivery of the feasibility study, Lundin and Reservoir will be responsible for funding the development of the Upper Zone on a pro rata basis (75%/25% respectively) and each will be entitled to its pro rata share of economic benefits of the Upper Zone. Freeport, Reservoir and Lundin will be responsible for funding of the development of the Lower Zone on a pro rata basis (54%/25%/21% respectively) and each will be entitled to its pro rata share of economic benefits of the Lower Zone.

Key Investment Highlights

• High grade copper and gold deposit: High grade copper and gold epithermal deposit overlying potentially large porphyry-style mineralization.
• Located in a historic mining region: Project stands to benefit from existing extensive infrastructure which is in place to support the nearby RTB Bor mining complex that has a long mining history.
• Lundin core competency: Size, quality and stage of the Upper Zone is ideal for Lundin Mining and fits well with our exploration, project development and underground base metals operating skill sets.
• Staged development: Staged development of the Upper Zone and Lower Zone will allow time to quantify and fully develop the Lower Zone potential to advance this prospective large-scale deposit in an optimal manner.
• Balanced acquisition cost: Total acquisition cost is paid over time and is directly tied to key project development and commercial operations milestones.
• Excellent exploration potential: Timok project comprises a total of four mineral licenses covering an area of over 200 square km of prospective ground.
• Minority interest in potential large-scale asset: Provides Lundin with an opportunity to participate in a potential large-scale porphyry deposit.

Transaction Overview

Timok Project Joint Venture

The Timok project is currently held 55% by Freeport and 45% by Reservoir. Freeport is currently operator of the project and is fully funding the project pursuant to a joint venture/shareholders agreement ("Timok JVSA") dated December 15, 2015. Upon the delivery of a feasibility study, Freeport will earn an additional 20% interest, for a total project ownership interest of 75%, at which time Reservoir will be required to contribute its pro rata share of development expenditures. Freeport may cease to sole fund at any time, in which case it would not be entitled to earn the additional 20% interest.

Subject to the ROFO, upon the completion of the transaction, Lundin's ownership interest in the Timok project will be as follows:

• 55% of the Upper Zone (Reservoir 45%), and
• 15.4% of the Lower Zone (Freeport 39.6%, Reservoir 45%)

Following the delivery of the feasibility study upon which Freeport's interest in the project will increase to 75%, Lundin's ownership interest in the Timok project will be as follows:

• 75% of the Upper Zone (Reservoir 25%), and
• 21% of the Lower Zone (Freeport 54%, Reservoir 25%)

Purchase Price

Total consideration of up to US$262.5 million is payable as follows:

• US$135 million payable to Freeport upon closing of the transaction
• Up to a maximum of US$20 million to be spent by Lundin in connection with agreed exploration and study work on the Lower Zone
• US$45 million payable to Freeport upon the earliest to occur of (i) a build decision on the Upper Zone, and (ii) access to any ore body for direct ship ore
• US$50 million upon the achievement of commercial production
• Up to US$12.5 million in recoupment of project expenditures

Project Overview

The Timok project is located in eastern Serbia and is currently centred on the development of the Cukaru Peki deposit located within the Brestovac-Metovnica mineral license. The project contemplates the development of a high grade massive and semi-massive sulphide deposit and conceptually, an underlying deep seated copper-gold porphyry deposit. The Cukaru Peki deposit is located approximately 6 km south of the famous century-old RTB Bor copper-gold mining/smelting complex. The region has a rich mining history and is complete with the necessary infrastructure and skilled workforce.

Please refer to Reservoir's news release dated January 27, 2014, and to the NI 43-101 Technical Report dated January 2014 for the initial mineral resource estimate for the Upper Zone.
