Managem SA 85 % Indirect
In 2016, in the context of the partnership with Avocet Mining, Managem took an equity stake of around 40% in the JV. This was increased to 70% following the finalisation of the project feasibility study in 2018. In 2019, Managem launched the financing programme for the construction of Tri-K, amounting to an investment of 176m USD.

June 18, 2019 - Managem has taken control of the Tri-K gold project in line with the Group’s strategy to increase its gold activities across Africa and to reinforce its footprint in the Republic of Guinea. The remaining 30% stake held in the JV by Managem’s partner Avocet Mining has been acquired for 21 M USD.

Managem’s stake in the holding company of SMM (Les Sociétés Minières de Mandiana), owner of the Tri-K exploitation permit, now stands at 85% with the remaining 15% owned by SOGUIPAMI (Guinean Mining Estate Company).

Deposit type

  • Orogenic
  • Porphyry

Summary:

The Koulékoun deposit is part of a NW-striking and steeply dipping porphyry hosted orogenic disseminated style mineralisation system. The dominant geological feature is massive, quartz feldspar porphyry, typically 20-80 metres wide. This has been drilled to a maximum vertical depth of 400 metres and is open along strike and at depth. An important feature is a younger, sub-horizontal dolerite dyke of Mesozoic age, which cuts the mineralised geology and controls the position of the water table and therefore restricts the depth of weathering at Koulékoun to 80 metres. Gold grades are higher in the intersection of the porphyry dyke complex and locally occurring NE striking structures.

The Kodiéran deposit is located in sediments close to the contact of a large diorite intrusive to the west. The bulk of Kodiéran is located in a deeply weathered saprolite profile where the ore is weathered to a depth of up to 100 metres. Mineralisation dips shallowly to the west and is 20–60 metres thick. Mineralisation has been tested over 2,500 metres along strike to date and remains open along strike and at depth.
