Leveraging our technical expertise, base metals focus and financial strength, we believe further opportunities exist to create meaningful stakeholder value. The addition of Chapada further solidifies Lundin Mining’s position as a leading intermediate base metals producer with high-quality low-cost copper exposure."

Chapada Overview1

Located in Brazil’s Goiás State, Chapada is expected to produce approximately 54.5 kt of copper and 100 kozs of gold, or approximately 75 kt of copper equivalent2, in 2019 at co-product cash costs of $1.60/lb to $1.80/lb copper and $430/oz gold equivalent based on latest Yamana guidance. In 2018, the operation produced approximately 58.6 kt of copper and 121 koz of gold, or approximately 82 kt of copper equivalent3, at co-product cash costs of $1.74/lb and $388/oz gold equivalent, respectively.

Since production commenced in 2007 to the end of 2018, the operation has processed 225 Mt of ore grading 0.38% copper and 0.33 g/t gold, producing approximately 743.5 kt of copper and 1.6 Moz of gold in concentrate. Potential process plant expansions are currently being studied and based on work completed to date by Yamana, a phased approach shows potential to sustain annual production in the range of 68.0 kt to 72.5 kt of copper and 100 koz to 110 koz of gold until at least 2034, as disclosed in Yamana’s fourth quarter and full year 2018 results news release dated February 14, 2019.

The Chapada orebodies are part of a large copper-gold mineralized system located in gently undulating terrain at low elevation, approximately 270 km northwest of the national capital of Brasilia. The operation is connected to the national grid via a private powerline with excess capacity for expansion.

Asset Highlights:

  • Mine operations – traditional open-pit truck and shovel operation with a relatively low strip ratio and benefiting from an in-pit crusher. Mine production is currently from three open pits in close proximity. Collectively, these open pits are the Chapada mining area.
  • Processing – conventional crush, grind and flotation processing producing a gold-rich copper concentrate. The Chapada concentrator is located at the northwest end of the pit rim and is designed to treat sulphide ores at a capacity of approximately 65 ktpd or 23.4 Mtpa. In 2018, the treatment plant processed an average of 63 ktpd with average copper and gold recoveries of 82% and 63% respectively. Plant expansion opportunities to increase the processing rate to a range from 28 Mtpa to 32 Mtpa are currently being studied by Yamana and Lundin Mining intends to evaluate further.
  • Copper concentrate – clean copper concentrate with significant gold by-product credit. During mine operations, the copper concentrate grade is expected to be between 24% and 25% copper with gold grades between 10 g/t and 15 g/t and silver grades between 40 g/t and 45 g/t.
  • Operating costs – co-product cash costs are expected to be $1.60/lb to $1.80/lb copper and $430/oz gold equivalent in 2019 based on latest Yamana guidance. Operating costs are tracked and well understood as the mine has been in production since 2007. Life-of-mine average unit operating costs are expected to be $8.03/t processed, consisting of mining, processing, and site general and administrative costs.
  • Mineral Reserves – Chapada Zone copper Mineral Reserves are estimated by Yamana to be 664.6 Mt at an average grade of 0.25% copper and 0.16 g/t gold, containing approximately 1.68 Mt of copper and 3.48 Moz of gold estimated using a copper price of $3.00/lb and gold price of $1,250/oz. Additional gold Mineral Reserves in the Suruca Zone of 65.2 Mt at an average grade of 0.51 g/t gold, containing 1.06 Moz of gold estimated by Yamana using a gold price of $1,300/oz. The copper Mineral Reserves support a 28-year operational life at the current processing rate of 23.4 Mtpa.
  • Tailings facility – The tailings storage facility (TSF) is located to the northwest of the Chapada open pit. The TSF is comprised of three dykes, each of which is constructed by the centreline method. The Main Dyke and Dyke III comprise compacted earth fill starter dams that have been subsequently raised using cyclone tailings. Dyke II is an entirely compacted earth fill dam and retains the TSF supernatant water. Due diligence was performed on the TSF and related infrastructure by Lundin Mining’s Technical Services group and independently by a leading third-party consultancy.
  • Communities and Employees – acquisition of an established operation with a proven track record, high-quality operating team and experienced workforce drawn from local communities.

Expansion Potential

Several initiatives are underway to further improve the performance of the Chapada processing plant following optimization projects completed in 2016 and 2017 which increased copper and gold recoveries, according to Yamana’s fourth quarter and full year 2018 results news release dated February 14, 2019. The next phase of this optimization, involving expansion of the scavenger flotation circuit, is expected to increase copper and gold recoveries by a further 1.5% to 2.0% with commissioning expected in the second quarter of 2019.

In addition, Yamana has been assessing plant expansion opportunities to increase the processing rate to a range from 28 Mtpa to 32 Mtpa and the relocation of some plant infrastructure to allow the push-back of the pit wall for the development of the Sucupira deposit. Lundin Mining intends to further evaluate these and other value creating scenarios for expansion by leveraging our technical expertise, financial strength and a copper-focused exploration potential of the mineral properties.

Yamana will also receive contingent consideration if certain gold price thresholds are met and development of a pyrite roaster is completed, as outlined below:

Up to US$125 million in aggregate over five years of contingent annual gold price payments based on the following structure:

  • a US$10 million payment if the gold price averages at least US$1,350/oz in any sequential annual period over the five years commencing on closing of the Acquisition,
  • a US$10 million payment if the gold price averages at least US$1,400/oz in any sequential annual period over the five years commencing on closing of the Acquisition,
  • a US$5 million payment if the gold price averages at least US$1,450/oz in any sequential annual period over the five years commencing on closing of the Acquisition.

A US$100 million contingent payment based on the development of a pyrite roaster which Lundin Mining will continue to evaluate.

In addition, upon closing Yamana will retain a 2.0% NSR royalty on any future gold production from the Suruca gold deposit.

Completion of the Acquisition is expected to occur early in the third quarter of 2019 and is subject to typical closing conditions, including third-party and requisite regulatory approvals. The Acquisition does not require shareholder approval of either party.

Existing Metals Sales Agreements

Yamana and certain of its subsidiaries related to Chapada had previously entered into metals purchase agreements which an affiliate of Lundin Mining will assume upon closing.

Sandstorm Gold Ltd. (“Sandstorm”) and Yamana entered a multi-asset stream transaction in October 2015.  Sandstorm is entitled to purchase 4.2% of the payable copper produced from Chapada up to a maximum of 3.9 million pounds (Mlbs) annually at 30% of the market price. The percentage of payable copper is subject to two reduction thresholds. Once an aggregate of 39 Mlbs has been delivered the percentage of payable copper reduces to 3.0%. Upon delivery of 50 Mlbs of copper the percentage of payable copper reduces to 1.5% for the remaining life of mine.

Altius Minerals Corporation (“Altius”) closed a copper purchase streaming interest in Chapada with Yamana in May 2016. Altius is entitled to purchase 3.7% of the payable copper produced from Chapada at 30% of the market price. The percentage of payable copper is subject to two reduction thresholds. In the event of a specified expansion at Chapada, which is deemed effective at such time as throughput increases to an annualized run rate of more than 26 million tonnes for a period of 150 days with a corresponding increase in copper production from a base rate for copper production of not less than 33%, the percentage of payable copper reduces to 2.65%. Also, upon delivery of 75 Mlbs of copper in aggregate the percentage of payable copper reduces to 1.5% for remaining life of mine.
