The pursuit for diamonds depends on experience, industry and location know-how and is supported by advanced exploration technology
Early Stage exploration
In the reconnaissance and discovery phase it is decided where to explore and identify potential targets for further analysis by sampling soil or stream sediments for indicators of the host rock that carried the diamonds to the surface; kimberlite. Once geophysical studies indicate a potential diamond deposit a drilling campaign is launched to extract minerals for examination.
Talvo focuses all its early stage exploration efforts on the Tshikapa Diamond Belt in the Kasai-Oriental Province of the Democratic Republic of the Congo.
Priority areas identified during the early stage exploration activities are targeted for high density sampling programs and geophysical surveys. A highly skilled exploration team will collaborate to combine their interpretations of geology, surficial sampling, and geophysics to short list the most promising targets for the advanced drill testing program.
The drill samples are analysed to estimate the grade of the potential deposit. Diamond grades are measured in carats per tonne (cpt), or carats per hundred tonnes (cpht) where one carat is equivalent to 200 milligrams of diamond. This information is used to calculate the potential carats of a possible mine.
Not every discovery is economically viable. In fact, 85 per cent of the discoveries do not contain diamonds.
Talvo works together with industry experts to confirm the viability of its discoveries and continuously increases its portfolio of new deposits.
