DIAMOND MINE PROJECT IN KEROUANE-MACENTA

The Kerouane and Macenta diamond mining concession consists of blocks totaling 280 square kilometers. Tigui Mining Group (TMG) holds 100% interest in the property.

 

CDGTN holds three diamond licenses on the property which is located in the Macenta and Kerouane Districts in the southeast of the Republic of Guinea, approximately 750 km east of the capital Conakry.The diamond licenses are situated within the southern portion of the Guinean diamond triangle, which hosts the majority of the country’s alluvial and hardrock diamond potential.The permits are divided as follow:

            

  • Kerouane Permits are 189km2

  • Macenta Permits are 91km2

 

CDGTN required an independent report to summarize the prospectivity of the three license areas. Based on existing data that CDGTN sourced and provided to SRK ES, SRK ES  prepared a series of recommendations for next step exploration activities and potential multi disciplinary studies.These recommendations were intended to direct  the process of taking each project through the stepped process of defining Mineral Resources.The report may be then used for fund raising and to actract investors who will support the development of the licenses.

 

It is unclear what level of commodity-specific and detailed commercial exploration has been conducted in these ares in the past although commercial companies presently operating around the area of interest may have historically undertaken work here. The Bureau de Recherches Geologiques et Minieres (France)(‘’BRGM’’) conducted regional geological mapping and exploration in the mid -20th century on behalf of the Guinea government. 

 

In Phase I, SRK ES proposes to undertake a desk based review of all the historical data sourced by CDGTN, relating to the licenses and to incorporate this with any relevant open source data that SRK ES is able to obtain. Phase II and Phase III have been outlined in the term of Reference section of the proposal.

 

SRK ES will provide a concise, detailed cost estimate for Phase II work based on past experiences,  which CDGTN will then be able to use for budgeting purpose.

 

Phase I Scope of work:

 

The review will consider and include:

  •  Prospectivity of the license areas

  •  Historical mining

  •  Level and detail of existing data

  •  Quality and reliability of the existing data

  •  Broadly determine the most prospective areas to the available data

  •  Review of any existing mineral resources

  •  Exploration strategy

  •  Recommendations towards Phase II (project development)

 

The data sourced by CDGTN include:

  • Exploration reports

  • Geological setting

  • Historic mining and production

  • Geological and drilling reports

  • Satelite imagery and geological maps

  • Exploration license boundary

  • Infrastructure and logistics network

 OVERVIEW

Key permits characteristics:

  • Located in the highly prospective Kerouane – Kissidougou – Macenta Diamond Triangle

  • Evidence of artisanal mining

  • Major multinational diamond mining companies near the permit

 

The licensed area is underlined by Archaean-age rocks of the Man Craton that consists principally of the magmatic granites, granite-gneisses, amphibolites and rare, quartzites.  The rocks are intruded by dolerites of suspected Jurassic age and Cretaceous-age kimberlites.  The kimberlites occur within a well-defined structural corridor referred to as the Bounoudou kimberlite zone.

 

Permits are located in the Gbonodou area, which has a history of significant diamond mineralization.  This area is one of the most prolific sources of mined diamonds in Guinea for its high grade and shallow alluvial deposits near Gbonodou.  These also include diamond-bearing kimberlites and associated secondary diamond deposits. 

Permits lie within the valley of the Dani River (a large north-south flowing river that drains into the Atlantic through Liberia).  To the west is the Ziami Mountain range where summits rise to over 1300m.  North is the Ziami Mountain’s summit with altitudes between 800m and 950 m.  This upland is drained partly by the headwaters of both the Diani and Milo Rivers, a north flowing tributary of the Niger River.

 

The high grades from bulk sampling at the Katcha Dyke at the northwest region of Droujba Project demonstrates its potential for Stellar Diamond to enlarge the project’s resource base, because of the presence of several large near gem quality diamonds up to 15.8 carats in size.

 

LOCATION

 

CDGTN’s permits are located in southeastern Guinea centered on the village of Gbonodou, which lies approximately 48km east of Macenta. The current exploration license is adjacent to West African Diamonds and Friendship Diamonds, both of which are fully own subsidiaries of Stellar Diamonds Plc. The current license was issued to CDGTN in 2010.  Previously, African Diamond Friendship had performed work on CDGTN’s permits. CDGTN's permits are easily accessible by road; it is approximately 800km from Conakry. 

 

The nearest landing strip is in Macenta with a 1.5-hour flight time to Conakry. During the summer of 2011, CDGTN performed mineralization studies. The main diamond deposits in Guinea are located in the prefectures of Kerouane, Kissidougou, and Macenta. The Baoule, Milo and Dani Rivers support the area. Some of industry leaders, such as DeBeers, Stellar Diamonds and The Aredor Concession, have a presence in this region.
