Petra Diamonds sells Botswana exploration assets

Petra Diamonds

Petra Diamonds (PDL.L) has agreed to sell its Botswanan exploration assets to Botswana Diamonds (BODP.L) for $300,000 and a 5% royalty on future revenue, the diamond miner, which is in the process of restructuring, said on Monday.

The purchase price will be payable in two equal instalments on or before August 31, 2021 and August 31, 2022, Petra said. Botswana Diamonds has the option to buy out the royalty for $2 million in cash.

Petra’s subsidiary Sekaka Diamonds Exploration (Pty) Limited, which Botswana Diamonds would take over, holds three prospecting licences including the KX36 project, which has an indicated resource of 17.9 million tonnes at 35 carats per hundred tonnes.

Botswana Diamonds managing director James Campbell said KX36 would be the company’s most advanced project in southern Africa, and Sekaka’s exploration database would also be “hugely complementary” to its current activities.

Petra, which has been planning to sell Sekaka since June 2018, said the deal is separate to the sales process it announced last month as part of its restructuring.

“The first tranche of the purchase consideration is not expected to be received until August 2021, making the sale too long-dated to help with Petra’s immediate cash flow challenges,” said BMO analyst Edward Sterck.

The sale still requires approval from the Botswana Competition Commission, ministerial consent in Botswana, and approval from Petra’s lenders and debtholders.

Campbell said he hopes the deal will be sealed by August 31.

Botswana Diamonds digs up first stones at South African mine

botswanadiamonds-southafrica

Botswana Diamonds said Tuesday that it recovered the first diamonds from plant commissioning activities on its Marsfontein mine in Limpopo, South Africa.

The announcement comes only days after it received a mining permit for diamond-bearing gravels and residual unprocessed stockpiles around the operation.

Chairman John Teeling said the plant was very close to reaching full operations following the installation of an in-field screen, two rotary pans, grease and x-ray recovery system.

“I am delighted with the rapid progress the team has made on-site and it is noteworthy that the first diamonds were recovered within two weeks of the mining permit being granted,” Teeling said.

The Marsfontein mine was operated for two years in the late 1990s, with a payback of its entire development costs in less than four days. The mine’s grade was 172 carats per hundred tonnes, at a bottom cut-off of more than 1.2 mm, containing many fancy coloured diamonds.

The surrounding deposits in question were overlooked when the mine was closed.

Diamond miners are struggling across the board, especially those producing cheaper and smaller stones where there is an over-supply in the market.

Buyers, those that polish and cut diamonds for retailers, have been hit this year by lower prices and tighter credit, prompting them to delay purchases.

De Beers, the world’s top diamond producer by value, has responded by axing production — with a target of 31 million carats this year compared with 35.3 million in 2018.

It has also announced it would spend more on marketing. At the latest sale, the company increased the amount of stones buyers were allowed to reject in each lot purchased from 10% to 20%, according to people familiar with the auction.

Lucara finds blue and pink diamonds at Botswana mine

lucara blue and pink rough diamonds

Canada’s Lucara Diamond continues to find gem quality, coloured diamonds at its Karowe mine, in Botswana, which in April yielded the 1,758 carat Sewelô meaning “rare find” diamond, the largest ever recovered in the African country.

The Vancouver based miner has now recovered a 9.74 carat blue and a 4.13 carat pink diamond from direct milling of the South Lobe, the area that yielded the famous 1,111 carat “Lesedi La Rona” in 2015.

The announcement comes on the heels of last week’s display of a 123 carat gem quality, top white, Type II diamond, found at the same section of the mine.

It also follows the recent sale of a 2.24 carat blue for $347,222 per carat.

Karowe, which began commercial operations in 2012, has this year yielded 22 diamonds larger than 100 carats, eight of them exceeding 200 carats.

Since the start of the year, the miner has sold 19 diamonds each with an individual price in excess of $1 million at its quarterly tender sales. This includes seven diamonds that fetched more than $2 million each, and one diamond that carried a final price tag of over $8 million.

“Lucara is extremely pleased with the recovery of these rare, sizeable, fancy coloured diamonds, which have the potential to contribute meaningful value to our regular production of large, high-value type IIa diamonds,” chief executive, Eira Thomas, said in the statement.

The precious rocks will be put up for sale in December, during the company’s fourth quarter tender.

Lucara, which has focused efforts on the prolific Botswana mine this year, is close to completing a feasibility study into potential underground production and life of mine expansion at Karowe.

Botswana Diamonds identifies five targets likely to be kimberlites

Botswana Diamonds Thorny River

The targets identified are very similar to the pipe that constituted the high-grade and famous De Beers Marsfontein mine, in so much as the pipe had little surface indication due to dolerite rock cover but grew and swelled below the dolerite.

Much of the Thorny River area geology is comprised of a dolerite dyke swarm.

John Teeling, chairman, comments:

“It has long been held that there should be high grade kimberlite pipes other than the Marsfontein mine in the Thorny River area.

“The geology made discovery difficult. New geophysical technology tries to see through the dense dolerite cover.

“The company pioneering the work, Subterrane, believe they have identified five targets likely to be kimberlites.

“We are working to better define where to drill. The targets are shallow so will not be expensive to drill”.

Conventional geophysical techniques have been unable to detect kimberlites under the dolerite including those that are deeper seated. Subterrane, a partner using its proprietary technology, enables the company to explore geophysical anomalies beneath the dolerite and those that are buried.

This could lead to the discovery of kimberlites similar to Marsfontein.

Thus far Subterrane has identified five such target areas within the Thorny River project.

Botswana Diamonds Shares Jump On Licence Extension

Botswana diamonds

Shares in Botswana Diamonds PLC jumped Thursday after it extended two “strategic” diamond licences for further two years, as it considered forming a joint venture to develop the projects.

Shares in Botswana Diamonds were 9.9% higher at 0.54 pence in London on Thursday.

Botswana Diamonds – through its wholly-owned Sunland Minerals Ltd subsidiary – extended the Prospecting Licences PL232 and PL235 in Botswana to the end of September 2021.

The firm explained the “key” licences were “strategically located” in the centre of the Kalahari Desert in Botswana, covering 500 square kilometres. Botswana Diamonds has already identified “prospective drill ready targets” following “intensive” work at the sites.

Botswana Diamonds said it was “already in extended discussions” with a “major” diamond producer regarding the formation of a joint venture for the next phase of the work on the licences.

Vutomi to sell diamonds recovered from South Africa project

Vutomi Diamonds

Botswana Diamonds associate Vutomi has received approval to sell diamonds recovered during a bulk sampling programme at the Thorny River project in South Africa.

The Thorny River bulk sampling project is a joint venture between SouthernEra, Palaeo and Vutomi.

SouthernEra holds a 40% interest in the project and provides processing services while Palaeo holds a 40% stake and serves as the mining contractor. The remaining 20% interest is owned by Vutomi, which provides the ground.

Until 10 June, 256 carat of rough diamonds were recovered. Sale of these diamonds from the bulk sampling will fund further development by Vutomi, in which Botswana holds a 40% stake.

The trenching programme has identified a hotspot at the project site with a thick, 4m wide kimberlite intersection, indicating a kimberlite blow.

According to Botswana Diamonds, the bulk sampling programme is expected to generate short-term cash flow while developing the mineral resource.

Botswana Diamonds’ partner, SouthernEra Diamonds, has included its coarse tailings dumps produced from the mining of the Marsfontein and Klipspringer diamond mines into the same revenue share partnership agreement.

Vutomi has obtained a Section 27 mining permit for a portion of the contiguous Marsfontein farm.

Part of this farm hosts rich M8 kimberlite dyke, bordering the Marsfontein diamond mine.

De Beers, Botswana Prep for New Sales Deal

De Beers Botswana

Botswana once again finds itself at a crossroads. The sparsely populated, landlocked country is in a constant battle to ensure the longevity of its diamond industry.

Recognizing that diamond mining will not last forever, the government’s beneficiation program has sought to establish cutting and polishing, trading, and auxiliary services in an effort to diversify its industry — and economy — away from its reliance on the mining sector.

Beyond mining

De Beers, which counts around 59% of its production by value in Botswana, has played no small part in that effort. It did so initially by earmarking a part of its rough supply to be manufactured in Botswana, and today there are 18 sightholders with factories in the country. In 2013, De Beers moved its sales headquarters to Gaborone, meaning that its 10 annual sights were taken out of London, thus diverting traffic and diamond-related activity to the African city.

Furthermore, the establishment of the parastatal Okavango Diamond Company that same year gave the government access to 15% of production by Debswana, its joint mining venture with De Beers. That was the first time substantial rough sales from Debswana took place outside of the De Beers system.

The 2011 agreement that governed those developments is up for renewal in 2020, and negotiations are expected to begin in the coming year. For its part, the government is seeking to increase supply to local sightholders as a means of creating more jobs, newly elected President Mokgweetsi Masisi told Bloomberg in May.

Some question whether Botswana can handle more manufacturing, given that a few factories have closed in recent years. If profitability remains the biggest challenge facing manufacturers, Gaborone has yet to prove itself as a viable center for high-volume cutting. Perhaps De Beers can play a further role there, too.

The government will also likely want to increase the percentage of Debswana supply that Okavango receives. And it might want to renegotiate greater access to the large and high-value diamonds Debswana recovers.

Digging deep

Botswana has some leverage in the relationship with De Beers. It owns a 15% stake in the group, with Anglo American holding the remaining 85%. And the two are equal partners in Debswana and in DTC Botswana, which sorts and mixes production for De Beers and Okavango.

De Beers, meanwhile, brings to the table its mining expertise and budget. In 2010, it committed to investing $3 billion over 15 years in the Cut-8 expansion of the Jwaneng mine — considered the world’s most valuable diamond-producing asset.

That project is already the main source of ore at Jwaneng and is expected to  extend the life of mine to 2030 and by some 93 million carats. Studies for the viability of Cut-9 are under way, which would further extend the life of Jwaneng. A final investment decision on the project is expected later this year, reports a De Beers spokesperson.

De Beers could use the potential Cut-9 investment, as well as funding extensions at the Orapa and Letlhakane mines, as a bargaining tool in negotiations with the government.

African investments

De Beers walks a similarly fine line in other African countries where it operates.

In South Africa, it may have to reduce ownership of its local businesses from 74% to 70% under the new mining charter, as the government wants to see more local black economic empowerment (BEE) involvement. That said, De Beers is engaged in a $2 billion project to develop underground mining at the Venetia asset. From next year, Venetia will be its only mine in South Africa, as it plans to close the Voorspoed mine. It has already sold the Finsch, Cullinan and Kimberley operations over the past decade.

Meanwhile, in May 2016, De Beers signed a 10-year sales agreement with Namibia, in which it ceded 15% of local supply to the government and promised more diamonds to local cutters. The company subsequently announced major investments in its marine mining operations off the Namibian coast.

It’s that give-and-take that Masisi is hoping will result in a “win-win” for both parties as they negotiate their next long-term deal — especially given that so much of Botswana’s future diamond production depends on Jwaneng’s expansion.

“We have had a wonderful relationship with De Beers, and we expect that relationship to be even more cemented,” the president told Bloomberg in May. “The returns [from the Jwaneng development] are going to be realized in the period of the next deal. This is a marriage we’re after.”

Botswana Diamonds picks up high potential kimberlite pipe in South Africa

rough diamonds

Botswana Diamonds has been awarded the priority 2.5 ha Mooikloof kimberlite pipe concession. Using recently developed exploration techniques it will re-assess this high potential pipe.

The award of the Mooikloof Prospecting Licence is an important development for Botswana Diamonds.

Mooikloof was last prospected in 1986. The adjacent Oaks mine was owned and successfully operated by De Beers. The Oaks mine had a grade of 53 cpht at a value of $156 per carat.

The large flagship Venetia mine, operated by De Beers, is close by and in the same general geology.

Based on Botswana Diamond’s experience elsewhere, it suspects that past explorers may have systematically under estimated the kimberlite pipe size, grade and diamond quality of the Mooikloof kimberlite.

It will deploy state of the art exploration techniques to reassess the Mooikloof kimberlite, and maybe open another by passed kimberlite pipe development.

Botswana Diamonds has now received the Technical Economic Evaluation Report on the Thorny River Project.

The deposit is between 1.2 and 2 Mt, the grade is between 46 and 74 cpht and carat values between US$120 and $220 per carat.

The Technical Economic Evaluation Report indicated positive economics could potentially be achieved using the top end of the grade and value ranges, assuming additional kimberlite volume of similar grade and value can be defined with further exploration.

While not a Scoping Study as Botswana Diamonds had previously envisaged in the announcements dated 15 February 2018 and 21 March 2018, the Technical Economic Evaluation Report has provided the company’s directors with sufficient information to conclude that the Thorny River Project requires further investigation.

Consequently, the directors are considering the company’s various technical and commercial options, which will be studied simultaneously with ongoing exploration.

Drilling at Ontevreden confirmed the existence of a kimberlite pipe, but showed the pipe to be smaller than the previously indicated geophysical anomaly.

Given Botswana Diamond’s attractive priorities elsewhere, it now proposes no further work on Ontevreden.

“Significant progress has been made on our joint venture projects in South Africa,” comments Botswana Diamonds chairman, John Teeling.

“Analysis shows that a mine on the Thorny River deposit could be profitable assuming positive results from additional exploration. Now we must refine the volume, grade and value estimates while working on the mining model.

“But modern mineral exploration technology is not a magic bullet. Modern geophysics indicated a 0.7 ha pipe at Ontevreden. Our drilling confirmed a smaller pipe, which is not currently commercial”.
