Meridian Mining Completes Due Diligence and Proceeds with Investment in Tin Project in Rondônia, Brazil

  • Positive due-diligence confirms potential for tailings reprocessing and regional exploration
  • Tailings Reprocessing Area expanded to more than 875ha

AMSTERDAM, March 16, 2017 /CNW/ - Meridian Mining S.E. (TSX V: MNO) ("Meridian" or the "Company"), today announced that, through its wholly-owned subsidiary Meridian Mineração Jaburi S.A. (formerly named Brasil Manganês Corporation Mineração S.A.) ("Meridian Brasil"), it has successfully completed its due diligence on the Bom Futuro tin joint venture in the state of Rondônia, in Northwest Brazil and has notified the Cooperativa de Garimperiros de Santa Cruz Ltda. ("Coopersanta") and Cooperativa Metalúrgica de Rondônia Ltda. ("Coopermetal") (together the "Cooperatives"), that Meridian Brasil will proceed with the transactions contemplated in the investment agreement (the "Investment Agreement") previously announced on December 19, 2016. 

Due Diligence

Meridian Brasil has completed the preliminary technical audit of the Tailings Area and has completed initial exploration on the Central Area and the Non-Explored Area. Initial results were announced in the news release dated February 15, 2017. Key highlights to date include:

  • Tailings program: 361 auger holes have been completed. Peak composite grades of 0.13% tin. Encouraging thicknesses of tailings were encountered in the Jacare Leste area, where auger holes terminated still within tailings at depths of up to 10m. This area has been prioritized for initial resource evaluation, with percussion drilling commencing to penetrate the full thickness of the tailings profile. Maximum depths of 18m have been encountered where the tailings infilled older valley systems.
  • Exploration: The core drilling program has concluded with 11 holes completed for 1,288 metres. Results confirm that pegmatites and quartz veins containing coarse cassiterite persist at depth in outward-dipping ring structures around the hill (complete analytical results pending). Trial geophysical surveys indicate that a combination of ground magnetics, induced polarisation techniques and ground penetrating radar assist in the definition of primary structures and palaeochannel positions. The orientation surveys provide a valuable template for expansion into covered areas regionally through the joint venture area.

  • Provisional metallurgical testwork supervised by independent consultant Ian Gordon shows positive results with finer cassiterite fractions amenable to concentration through Falcon Concentrators and coarser material amenable to jigging. Results from spiral tests are pending. The next phase of testwork will utilise composites gathered through the percussion drilling program.

"We are pleased with the progress we made during the due diligence period and outcomes of our due diligence work program," said Anthony Julien, President and Chief Executive Officer of Meridian. "We continue to receive excellent logistical support from Coopersanta, our joint venture partner. Together, we believe there are excellent opportunities to apply modern technology to optimize recoveries and explore for new tin deposits in this important mining centre. We are pleased to receive such positive results and to finalize our technical audit so we can continue to advance the joint venture together with the Cooperatives."

Cooperative Update

During the due diligence period, the Cooperatives obtained a favourable commitment from the Public Prosecutor's Office and Centrais Eléctricas de Rondônia S/A – CERON (Electrobrás) ("CERON") for the granting of the necessary approvals for Meridian Brasil to take over construction of a power transmission line. The Cooperatives also approved a Tailings Reprocessing Permit and the Exploration Permit over the Total Area.

In addition, the Cooperatives agreed to significantly expand the Tailings Reprocessable Area to 878.80ha from 492.57ha initially contemplated in the Investment Agreement. In addition, the Cooperatives have also granted to Meridian Brasil the exclusive right to carry out mining operations in the Non-Explored Area, prior to the completion of a feasibility study as originally contemplated in the Investment Agreement, provided that the committed investment and exploration works continue. The interests of the parties in the mining operations will be 80% for Meridian Brasil and 20% to the Cooperatives.

Investment Arrangement

Meridian Brasil can earn an interest in up to three components of the Cooperatives' operation. Pursuant to the Investment Agreement, as discussed in further detail in the news release dated December 19, 2016, Meridian Brasil has: (i) the right to provide tailings reprocessing services on certain tailings deriving from the Tailings Reprocessable Area to the Cooperatives and will execute a formal services agreement in this sense with the Cooperatives; (ii) a right of first refusal on either the acquisition of the mineral rights or the provision of underground mining services in the Central Area; and (iii) the right to earn 80% of the Non-Explored Area surrounding the mines and, in addition, as mentioned above, can now (iv) exploit the Non- Explored Area, prior to the conclusion of the exploration phase and issuance of the feasibility study, provided that the committed investment and exploration works for this area continue.

The Bom Futuro mine has produced more than 192,000 tonnes of tin since its discovery in 1987, and is the largest producing tin mine in the Ariquemes district. The Ariquemes District, located in Rondônia, NW Brazil has produced approximately 3% of the world's tin supply over the past 30 years
