Thieves Steal 20ct. Diamond at Vegas Show

Two men stole a 20 carat diamond from an exhibitor’s booth at the JCK Las Vegas trade show, the Jewelers’ Security Alliance (JSA) said last week.

The men were able to slide open an unlocked display case on June 2 while employees were not looking, the organization alleged. One man then sat down at the booth and began speaking with an employee, while the second placed a catalog on top of the showcase. The second man then reached into the case and removed the stone.

The JSA has distributed pictures of both alleged thieves, but neither has been identified yet.

Botswana Diamonds picks up high potential kimberlite pipe in South Africa

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”.

Zimbabwe Forecasts Surge in Diamond Output

Zimbabwe’s rough diamond production will more than triple to 11 million carats in 2025, according to the nation’s state-owned mining operation.

Output will grow at an average of 21% per year from 3 million carats in 2018, a spokesperson for the Zimbabwe Consolidated Diamond Company (ZCDC) told Rapaport News Monday.

“This growth is anchored on investment of around $400 million across the entire diamond value chain in the next five years,” the spokesperson said.

In addition, the ZCDC named Killiam Ukama, an engineer, as the chairman of the ZCDC’s new board.

The ZCDC produced 1.8 million carats in 2017 from the controversial Marange diamond fields, where security forces killed more than 200 illegal workers in 2008. The company suspended sales for nine months last year as it carried out a restructuring, and resumed tenders in the first quarter of this year.
