Botswana Diamonds Starts Scoping Study To Find Potential Commerciality at Thorny River

February 19, 2018

Botswana Diamonds said that it has commenced a scoping study to determine the potential commerciality of the Thorny River Diamond Project, in South Africa. 

The study, it said, would further refine the volumes of diamonds in-situ, the grade and the value per tonne of ore. 

“A critical aspect will be to evaluate the processing and mining options,” said Botswana Diamonds. 

“This work is expected to take up to six months.” 

The company also said that further analysis of the work completed to date at Thorny River had led to an updated estimate of the diamond value range of $120-$220 per carat. 

Extensive drilling, geophysics and sampling work had been undertaken at Thorny River during the last twelve months. 

It said the estimated diamond grade range remained at 46-74cpht, while its estimated volume range also remained at 1.2 -2.1 million tonnes of kimberlite. 

“We now have a much better understanding of the geology and metrics of the Thorny River deposit. What is emerging is a project with similar metrics to the neighbouring Klipspringer Mine,” said company chairperson John Teeling. 

“We are now undertaking a detailed study to refine our processing, geological and commercial parameters.” 

The Thorny River Project was a consolidation of the Frischgewaagt, Hartbeesfontein and Doornrivier properties into a 2,771 hectare area in the Limpopo Province. 

It comprised the eastern extension of the kimberlite dyke/pipe systems on which the Klipspringer & Marsfontein Mines are located, both of which have been economically mined.
