Cyprium Mining to Acquire Controlling Joint Venture Interest in the Historic Potosi Silver Mine in Mexico

MONTREAL, QUEBEC--(Marketwired - July 28, 2015) - Cyprium Mining Corp. ("Cyprium" or the "Company") (TSX VENTURE:CUG)(TSX VENTURE:CUG.DB) is pleased to announce that it has entered into a letter of intent with Minerales Nacionales de Mexico SA de CV, Minera Potosi Silver S de RL de CV ("Minera Potosi") and Daniel Valenzuela (collectively, the "Potosi Partners"), pursuant to which Cyprium and the Potosi Partners have agreed to form a twenty year joint venture for the exploitation and exploration of the Potosi silver mine located in the historic silver rich mining district of Santa Eulalia in Mexico (the "Joint Venture").

The Joint Venture will also have the exclusive rights of possession, usage and operations to the San Guillermo processing facility which is located seven kilometers from the Potosi silver mine, as well as all of the exploration and exploitation rights to a property adjacent to the Potosi silver mine known as La Chinche. The Potosi silver mine, the San Guillermo processing plant and the La Chinche property are 100% owned by the Potosi Partners. Cyprium will initially acquire a 53% interest in the Joint Venture in return for a US$2.5 million financial commitment to the Joint Venture to be completed by December 31, 2016. The Joint Venture is expected to be finalized before the end of August 2015 and is subject to several conditions including, without limitation, receipt of all necessary regulatory and TSX Venture Exchange approval, and other usual conditions for transactions of this nature.

Mr. Alain Lambert, Chairman and C.E.O. of Cyprium stated: "We are proud to form this partnership with Daniel Valenzuela, a third generation miner of the Potosi silver mine and operator of the San Guillermo plant. The mine operated continuously for over thirty-four years before it closed in 1991 when commodity prices were low and a labour dispute lead to a strike. The Potosi Partners have successfully, but inconsistently, carried out small scale production between 1991 and 2012. Together, we will restart mining operations at Potosi and San Guillermo."

Mr. Lambert concluded: "When I was appointed CEO of Cyprium in May 2015, I was very clear about the number one strategic imperative for our company: to secure medium to long-term supply of mineralized material with acceptable head grades from nearby mines to fill up the capacity of the Cyprium operated processing plant in Aldama, Mexico. The Joint Venture also meets another strategic imperative we had set at the time: the acquisition or co-participation of existing mines and/or plants where we can deploy our financial resources and technical expertise for the benefit of our shareholders. Needless to say, the transaction announced today goes a long way towards meeting those priorities. The combination of owning the rights to an existing operating plant and a historic silver mine, especially of the scale of Potosi, is quite a unique proposition for a junior mining company."

Santa Eulalia is a world class polymetallic mining district located in the central part of the State of Chihuahua, Mexico, approximately twenty-two kilometers east of the City of Chihuahua. Mineralization in the area was originally discovered during the Spanish colonial period in the 1500's, and recorded production has occurred over more than 300 years. Santa Eulalia ranks as one of Mexico's primary silver and base metal producing districts with nearly 450 million ounces of silver and substantial amounts of lead and zinc mined. The nature of the deposit in the Santa Eulalia district is a carbonate replacement deposit and is the historically largest of its type in Mexico. Mineralization occurs in an area about 10 km in length and 5 km in width. Production and reserves for the district have been estimated to be about 50 million metric tons⁽¹⁾ with grades of 125-350 g/t Ag, 2-8% Pb and 3-12% Zn⁽¹⁾⁽²⁾, along with appreciable quantities of tin and vanadium. 

The Santa Eulalia district covers approximately forty-eight square kilometers and is divided into three areas, the West Camp, the Central Camp and the East Camp. The Potosi silver mine is located in the West Camp. The West Camp has produced most of the minerals from the district from an area 4 km long in a north-south direction and 2 km wide in an east-west direction, with the Potosi silver mine being one of the primary producers.

Groupo Mexico, through its subsidiary Southern Copper Corp. owns the Buena Tierra mine in the West Camp and the San Antonio mine in the East Camp. MAG Silver Corp. controls all of the ground to the immediate south, except for La Chinche, and between the West Camp and East Camp.

Mr. Cesar Duarte, Governor for the State of Chihuahua noted: "The Potosi silver mine is a significant asset which is central to the long and vibrant history of success of the Chihuahua mining sector. Cyprium's US$2.5 million investment in restarting the mine is in addition to Cyprium's recent US$400,000 investment in the Aldama plant. These investments will lead to the creation of several hundred direct and indirect jobs, as well as goods and services being purchased locally for the benefit of all residents of Santa Eulalia, Aldama and Chihuahua. Cyprium now joins larger Canadian mining companies such as Agnico Eagle Mines Ltd. and Goldcorp Inc. that have operating mines in Chihuahua. We look forward to providing them all the support they need to make their operations successful."

Strategic advantages and deal highlights

• All historic technical reports were preserved by the Potosi Partners and will be available to the Joint Venture.
  
  
• The Potosi silver mine, which is twenty-one level deep, stopped operating because of low commodity prices and a labour dispute, not because of lack of mineralized material.
  
  
• Much of the infrastructure at the mine such as buildings, while in need of renovations in some cases, is still available.
  
  
• The Santa Eulalia mining district is one of the most researched mining districts in Mexico.
  
  
• The Potosi silver mine is located approximately 22 kilometers from downtown Chihuahua and is 100% accessible by paved roads.
  
  
• The Potosi silver mine is located only 42 kilometers from Cyprium's Aldama plant.
  
  
• The team currently working at the Aldama processed at that plant mineralized material from the Potosi silver mine in the last few years and all the technical information is available to the Joint Venture.
  
  
• The Potosi Partners invested over US$600,000 between 2010 and 2012 on the rehabilitation of the San Guillermo plant as part of a plan to deliver a processing plant with capacity between 400 and 500 tons per day. The Joint Venture intends to make investments in the San Guillermo plant in 2016 as and when additional production capacity is required over and above the Aldama plant existing capacity.
  
  
• The Aldama plant has enough capacity to process the planned initial production from the Potosi silver mine meaning that the Joint Venture does not need to immediately invest in a processing plant in order to resume production.
  
  

Concurrent Transaction with Trafigura

Concurrently with the signing of the final documentation to form the Joint Venture, the Joint Venture will enter into a renewable six year commercial agreement pursuant to which it will sell, and Trafigura Mexico SA de CV ("Trafigura") will purchase, metals from the Potosi silver mine in accordance with the terms contained in the said commercial agreement (the "Offtake Agreement").

Juan Antonio Moran, Commercial Manager - Mexico at Trafigura said: "Trafigura is pleased to start working with Cyprium Mining in order to restart the Potosi silver mine. Our relationship with the mine goes back several years and we believe the mine still has good production and exploration potential. We also look forward to evaluating other opportunities to work with Cyprium in Northern Mexico."

Other Transaction

In addition, an arms' length third party holds certain rights with respect to the Potosi silver mine and San Guillermo plant, including the rights to mine at the Potosi silver mine and the rights of possession, usage and temporary operation of the San Guillermo facilities (the "Rights"). Concurrently with the entering into of the Joint Venture and the Offtake Agreement, Cyprium or NewCo will purchase the Rights from the third party. The total purchase price for the Rights to be paid by Cyprium or NewCo will be US$746,846 (the "Purchase Price"). The Purchase Price shall be paid as to US$400,000 in cash at closing, and US$346,846 to be paid in monthly installments starting eight months after closing.

Development Plan

The Joint Venture intends to carry out two principal projects in 2015. The first project is the rehabilitation of shaft #3 of the Potosi silver mine. The goal of this project is to gain access to mine levels 2, 3 and 4 where the Potosi Partners last mined between 2010 and 2012. The budget for the rehabilitation of shaft #3 and the working capital required to start small scale production are estimated at US$100,000 in 2015 with a further US$100,000 investment being planned in early 2016 to increase production capacity. Once production resumes, Cyprium intends to send the mineralized material extracted through shaft #3 to the Aldama plant.

The second project of the Joint Venture has an estimated budget of US$1.1 million and involves the rehabilitation of the larger and deeper shaft #5 which will provide access to all levels of the Potosi silver mine down to level 10. The rehabilitation of the shaft #5 is expected to take eight months. Once shaft #5 is rehabilitated, the initial exploration and production will focus on level 9 and 10 where the most recent exploration activities have taken place.

The rehabilitation of the San Guillermo processing plant is planned for 2016. The timing and final technical plans will be dependent on expected production at the time and the capacity available at the Aldama plant.

Geological Setting, Deposit Type and Mineralization

Mineralization in the Santa Eulalia district is characterized by massive sulfides, dominantly pyrrhotite, sphalerite, galena and pyrite that are hosted mainly in horizontal mantos and steep chimneys of sulfide material that replace limestone, with some breccia bodies also occurring. Mineralized bodies occur along laterally continuous discrete structural zones that mainly trend in a north-south orientation, with mineralization forming preferentially in certain stratigraphic units. Past mining has reached to as much as 700 meters depth below the surface on 21 levels. Production in the West camp was diminished until the late 80's with the discovery of new mineralization. Currently there is little production in the district.

Exploration Program

Cyprium has started an underground exploration program consisting of channel sampling. The primary objective is to audit past exploration results from over 500 sample results taken in 2014 on levels 9 and 10 of the mine by an independent third-party. This sampling includes taking duplicate samples as well as sampling in new areas. This sampling program will also include additional channel samples taken on levels 3 and 4 of the mine where initial production will be focused.

National Policy 43-101 Report

Cyprium has engaged Dr. Craig Gibson to complete a National Instrument 43-101 report with respect to the initial mine levels 2, 3 and 4 of the Potosi silver mine. It is expected the report will take two months to complete. The report to be prepared by Dr. Gibson shall not contain a resource or reserve calculation.

Joint Venture Structure

The Joint Venture will be carried-out through a new company to be created ("NewCo") which will be initially owned as to 53% by Cyprium and 47% by Minera Potosi. The US$2.5 million financial commitment of Cyprium, which needs to be completed by December 31, 2016, shall consist of a US$1.9 million equity investment in NewCo and a three-year, 12% loan to NewCo in the amount of US$600,000 to be advanced at the entering into of the Joint Venture. In consideration for the loan, Cyprium will be entitled to a 0.75% ten year royalty on sales of concentrates from the Joint Venture. If Cyprium fails to invest the US$1.9 million by December 31, 2106, Cyprium's percentage ownership in NewCo shall be reduced proportionally. Cyprium will exercise operational control of the Joint Venture. The Joint Venture will be for a duration of twenty years, with right of renegotiation on the tenth anniversary if the Joint Venture is not processing an average of 400 tons per day on at the anniversary date. Mr. Carlos Arzola, a director of Cyprium, was involved in identifying the Joint Venture opportunity and played an essential role in bringing the parties together. Mr. Arzola has and continues to assist in the negotiations for the formation of the Joint Venture. Subject to the parties entering into a formal agreement for the formation of the Joint Venture, the Company will pay a finder's fee to Mr. Arzola of US$25,000 in cash and the Company will also issue to Mr. Arzola 500,000 common shares of Cyprium (the "Finder's Shares") with a deemed value of $0.14 per share. The issuance of the Finder's Shares is subject to approval of the shareholders of Cyprium and the approval of the TSX Venture Exchange and the Finder's Shares will be subject to a four-month and one day hold period, in accordance with the applicable securities laws.

In consideration for transferring the exploration and exploitation rights to the La Chinche property to the Joint Venture, Cyprium will, subject to regulatory approval, issue 1,000,000 common shares of Cyprium with a deemed value of $0.14 per share and 100,000 five year warrants exercisable at a price of $0.17 per share to Daniel Valenzuela.

Financing of the Joint Venture

The investment by Cyprium in NewCo will be financed from the proceeds of the previously announced non-brokered private placement (the "Bond Financing") of bonds of Cyprium in the aggregate amount of US$4,500,000. It is anticipated that the second tranche of the Bond Financing for an amount of US$2 million (the "Second Tranche Disbursement") will close concurrently with or before the entering into of the Joint Venture. The Bonds will bear interest at a rate of 12.5% per annum, calculated and payable quarterly in arrears commencing on September 30, 2015. Subject to closing the Second Tranche Disbursement, the Corporation will pay a finder's fee of 8% of the Second Tranche Disbursement in cash and the Corporation will also issue to the finder 1,039,423 share purchase warrants with an exercise price of $0.14 per share for a period of three years. Pursuant to applicable securities laws, all securities issued pursuant to the Bond Financing will be subject to a hold period of four months plus one day following the date of issuance of such securities.
