Botswana is continuing to establish itself as a diamond exploration hot spot, with Pangolin Diamonds (CVE:PAN) hitting a new 52-week high on Monday after two kimberlite discoveries at its Tsabong North project in Botswana last week.

One of which was among the world's largest at 270 hectares.

Pangolin discovered a new kimberlite - Martin 01 - at its Tsabong North project, which is located about 12 kilometres north of the giant Magi kimberlite announced a day earlier.

The Magi kimberlite stems from its findings earlier this year of two kimberlites - Magi-01 and Magi-02 - at the project. The company said that these Magi kimberlites are in fact part of a single intrusive complex, with a total surface area estimated at 270 hectares.

This compares with the Se251 kimberlite in Angola that measures 220 hectares - another of the world's largest kimberlites - and the MK1 in Botswana that measures some 180 hectares.
