The intrinsic attraction of tanzanite and the finite nature of a single known resource at the foothills of Mount Kilimanjaro in northern Tanzania are undoubtedly part of tanzanite’s allure.
TanzaniteOne is the largest and most scientifically advanced miner and supplier of rough tanzanite, a unique position that affords it the opportunity to support and influence the entire channel, from mine to market, ensuring that maximum stakeholder value is achieved at each stage of the process.
Our leading position in the tanzanite market has ensured TanzaniteOne the recognition and respect of its peers and provides the opportunity for expansion into a broader range of PCGs located at various key sights around the world.
Objective To be world’s leading premium coloured gemstone mining company
Tanzanite Strategy Continued exploration, expansion and improvement of the available skills, resource base and market positioning of this magnificent product.
The world's only known source of tanzanite is situated in the Simanjiro district of Tanzania, 70km south-east of Arusha and 16km south of Kilimanjaro International Airport. In 1990, the Tanzanian Government demarcated the tanzanite mining area into four blocks: A, B, C and D, measuring approximately 5km by 2km in total. anzaniteOne owns the mining licence for Block C, the largest block at the centre of resource.
Tanzanite is located within a relatively complex geological environment and is found in 'chocolate-tablet' boudin structure, typically located in the hinges of isoclinal folds (folds dipping in the same direction) present in the ore body.
TanzaniteOne has made significant strides towards delineating the tanzanite deposit. Deep hole drilling, geophysics, geochemical analyses and structural and geological mapping have all increased our level of geological knowledge and confidence. our drilling programme has shown that the lower horizon, which hosts the economic mineralisation, extends three times further dip than initially anticipated. This databank of proprietary geological know-how is unrivalled and will become more important than ever as mining operations deepen and the artisanal mining styles employed on the other licence blocks become redundant.
A conservative estimate of TanzaniteOne's resource, and as published at the time of listing on AIM in 2004, would place the figure at 63-83 million carats. At an average price of $ 12/carat in the rough, this represents an estimated $756 million to $996 million in the ground.
