Orea signs binding LOI to acquire gold assets in Colombia

Global Mining Review,

Orea Mining Corp. has announced the signing of a binding letter of intent (BLOI) to acquire gold projects with an existing ore processing facility, including significant plant and equipment, in Colombia, South America.


  • The BLOI was signed with the sellers on 21 December 2020 to acquire a 100% interest in 13 mining concessions in 3 separate blocks (the project) located in the Department of Bolivar, northern Colombia, South America.
  • The execution of the corresponding definitive agreement is subject to the successful completion of due diligence by Orea within 90 days from the signing of the BLOI.
  • The project covers a total surface area of 250 km2 encompassing numerous artisanal gold mines.
  • Orea considers the project to be highly prospective for large epithermal and porphyry gold-copper deposits.
  • The construction of a fully-permitted ore processing plant on the land holdings is near completion and will be fundamental to formalising mining in the region.

“After evaluating numerous opportunities in 2020, Orea is delivering on its promise to add a quality gold project to its portfolio, in line with its responsible mining approach,” commented Rock Lefrancois, President and CEO of Orea.

“As our Montagne d’Or Gold Project in French Guiana has entered mine permitting, this new acquisition within the emerging Northern Andean copper-gold province will be the driver for exciting development and further growth in 2021,” he added.

The project lies within the northern San Lucas mountain range, northeast of the Colombian Central Cordillera. The region is known for its gold production since pre-colonial times, which is presently subject to prevalent formal and informal artisanal mining. The project area is characterised by moderate topography and low elevations ranging from 40 – 700 m above sea level.

As is recognised all over the northern San Lucas range, numerous small-scale near-surface artisanal underground mines are documented over the project and surrounding areas. The mines are developed along narrow sulfide-rich quartz veins with economic grades in gold, silver, copper, zinc and lead. Within the northern San Lucas range these polymetallic veins are associated with granitic intrusion of Jurassic age. A potential second phase of the gold mineralisation has been recognised on the project interpreted to be associated with younger porphyritic domes of Tertiary age, where mineralised vein systems exhibit epithermal textures with associated alterations. The relation of the polymetallic vein-type mineralisation with buried porphyry-type gold-copper systems has not yet been investigated on the project.

Lefrancois said: “The acquisition of this large land package offers excellent exposure for the discovery of epithermal and porphyry gold-copper deposits for the implementation of industrial-scale mining in the region and almost immediate cash flow from the processing plant.”

Processing plant

As a business unit separate from exploration activities, an ore processing plant is under construction on the project to treat artisanal ore feed from mines within the project and surrounding mining concessions. The plant is estimated to be 75% complete and US$3 million capital expenditures are required for commissioning of the plant at a rate of 150 tpd. Crushing and grinding capabilities can be increased to process 200 to 300 tpd. The plant flowsheet uses standard crushing and grinding, gravity separation of the free gold and non-toxic chemical reagents flotation to produce a concentrate. No cyanide leach circuit is required to obtain >90% recovery of the gold. The flotation concentrate may be shipped to a refinery via Barranquilla, Santa Marta or Cartagena on the Caribbean coast. Free gold is poured into doré gold bars and exported via Medellin for refining.

A corporate and social responsibility strategy for responsible and sustainable development of the region has been implemented by the seller. Social licensing was achieved by toll mining. Social efforts have also been advanced in the different areas of influence with the support of local authorities such as vaccination days, educational talks, improvement of school infrastructure, tropical storm season relief, among others.

Project plans

Orea’s initial objectives for the development of the project include:

  • Project and regional scale geological evaluation and consolidation of the land package.
  • Exploration strategy, targeting and resource drilling.
  • Inventory of artisanal mines on the project and surrounding mining concessions.
  • Secure toll mining contracts with artisanal miners.
  • Commission and optimise processing plant at 150 tpd.
  • Mechanise and assure security protocols at artisanal mines to increase ore feed.
  • Increase plant processing rate to 200 to 300 tpd.

Terms of acquisition

The project is held within a Colombian private company (the Colombian entity), and the acquisition of the project will be completed in two stages with key terms as follows:

Stage 1

  • Acquisition of ~44% of the Colombian entity in exchange for cash of ~US$105 000, 6.6 million shares of Orea, and granting a 25% net profit interest of the project mill output to the seller, capped at 300 tpd ore feed and a maximum of 13.3 billion Colombian pesos (~CAN$4.9 million) (the NPI)
  • Issue 5 million shares of Orea to a third party for the assignment of the right to acquire the Colombian entity.

Stage 2

  • Upon the NPI being paid in full, or an equivalent amount advanced to the seller, acquisition of 56% (the remaining shares) of the Colombian entity in exchange for 20.4 million Orea shares.

Upon closing of Stage 1, Orea will:

  • Have security of the remaining shares.
  • Be granted voting rights to the remaining shares.
  • Be appointed operator of the project.
  • Assume all economic benefits and risks to the Colombian entity.

“By structuring this transaction as a two-stage acquisition, we managed to effectively have 100% control immediately, with minimal dilution as the most significant share payment will be issued in the future, and the cash component will be paid through the NPI,” concluded Lefrancois.

The transaction contemplated under the BLOI is subject to the approval by the Toronto Stock Exchange.
