The first was to test the grade of the fresh kimberlite and the second was to confirm the grades of one of the mine dumps. Both were achieved, and proof of the fresh kimberlite grade paves the way for further exploration work on Marsfontein to target potential blows. The kimberlite grade is aligned with those achieved at Klipspringer mine and Thorny River, which are both nearby, indicating the considerable extent of the kimberlite dyke system. Options will be investigated on exploitation of the dumps once the nationwide lock down in South Africa is lifted and a sense of normality returns to diamond markets, post the global Covid-19 pandemic crisis.\"\n \n \n \n \n \n The results of the bulk sampling programme, including modelled results are illustrated in the table below:\n \n \n \n \n \n \n \n \n \n \n \n \n Source\n \n \n \n \n Sample Size (tons)\n \n \n \n \n No of stones\n \n \n \n \n Carats\n \n \n \n \n Raw Grade (cpht) +1.7mm BCOS\n \n \n \n \n Average stone size cts\n \n ...
