SA’s Vutomi project can start production end of 2018 – John Teeling


Botswana Diamonds entered into an option and earn-in agreement with Vutomi Mining and Razorbill Properties, a private diamond exploration and development firm in South Africa last February. It agreed to pay Vutomi a total of £942,000 in cash, of which £581,000 would be used to fund exploration activities. In addition, the company would issue 100 million ordinary shares of 0.25p each to Vutomi shareholders, after which the company would own 72 percent of Vutomi. The flagship project, Frischgewaagt, was in the Limpopo Province 300km north of Johannesburg and was immediately adjacent to the Marsfontein Mine which was previously operated by De Beers. It recently recovered 223 microdiamonds from 160kg of kimberlite drill core from the project. Botswana Diamonds said the kimberlite drill core results were modelled to an estimated grade range of 20 to 270 carats per hundred tonnes at a bottom cut off of 0.6 mm, with the largest stone being a white transparent crystal diamond falling in the -1.18+0.85 mm sieve. Company chairperson John Teeling told Rough & Polished’s Mathew Nyaungwa on the sidelines of the Botswana Resource Sector Conference in Gaborone that it was possible that they might consider some production by the end of next year, if not early 2019 as they were looking at the possibility of using other people’s plants rather than their own, a move that would significantly lower capital expenditure. Teeling emphasised that production was only feasible if they follow a low-cost regime, adding that the project won’t be “huge”, but the diamonds produced would be of “good quality”. He also commented on Botswana Diamonds’ three-and-half-year relationship with their joint venture partner, Alrosa as well as the implications of the liquidation of their partner in the Maibwe project, BCL.

Proximity doesn’t matter, your pocket does: Tanzanians interested in tanzanite jewellery can testify

19 june 2017

Tanzanite, a rare blue/purple gem, was discovered in the Merarani Hills of Manyara Region in northern Tanzania in 1967, a few miles from Arusha and Mount Kilimanjaro. It is used as a gemstone and of late Tanzanians are manufacturing quality jewellery as witnessed by our African Bureau Editor Mathew Nyaungwa during the Arusha Gem Show. However, in as much as this is an interesting development, most Tanzanians are said to be finding it difficult to afford jewellery made from a gemstone, which is only found in their country. Gem Tanzanite owner Osman Abdulsattar told Rough & Polished on the sidelines of the show early May that they had decided to make jewellery made of light (low quality) tanzanite and silver for the local market, to allow low income earners in the country get tanzanite for their engagement ceremonies.

Tanzania to cautiously extend ban on export of rough gemstones from tanzanite

22 may 2017

Tanzania, which imposed a ban on the export of rough tanzanite more than 1 gram to encourage local beneficiation, said it will cautiously extend the moratorium to other precious stones in the country once it has the capacity to cut and polish all gemstones, locally. Gemstones found in the East African country included tanzanite, ruby, tsavorite, garnet, emerald, sapphire and alexandrite. Commissioner for minerals Benjamin Mchwampaka told Rough & Polished on the sidelines of the Arusha Gem Fair, which took place early May, that they don’t want to “paralyse” the whole industry by imposing a blanket ban on the export of all rough gemstones when there is no capacity to add value in the country. He, however, said both government and the private sector had started training locals in cutting and polishing in preparation for the future ban of rough gemstones. Mchwampaka also said government would consider issues raised by mining companies following its directive to have them cede 30 percent of their equity to the “public” as well as list on the local stock exchange. He said Dar es Salaam was also engaging Petra Diamonds over its shares in Williamson Diamonds and a decision on whether it should be subjected to the new regulations that would be reached at after discussions. The Tanzanian government currently owns a 25 percent stake in the diamond mine. Below are excerpts of the interview.

De Beers sees sales volumes returning to “more normal” levels

15 may 2017

De Beers registered a higher than usual volume of sales in the first quarter following a “strong” rebound in demand levels for lower value stones during the first sales cycle of 2017. The unexpected introduction of demonetisation in India late last year had resulted in weak demand, albeit temporary, for smaller, lower quality rough diamonds from the Asian country’s cutting and polishing industry. De Beers had to temporarily put in place some additional flexibility for Sightholders purchasing a range of lower value rough diamonds following the introduction of the Indian demonetisation programme, as they recognised the challenges some customers would face as they adjusted to the new monetary environment. However, group senior manager, media and commercial communications, David Johnson told Rough & Polished’s Mathew Nyaungwa that the diamond giant was now projecting sales volumes for the rest of the year returning to more normal levels as demand was more balanced across the assortment. He said the group had already reverted to the normal supply situation with its Sightholders.
