The company said it had modeled the kimberlite at 270ha, which compares with the Se251 kimberlite in Angola, which measures 220ha, the MK1 kimberlite in Botswana, measuring 180ha, and the Mwadui kimberlite in Tanzania, measuring 146ha.

The new discovery stems from the company’s findings earlier in 2013 of two kimberlites, Magi-01 and Magi-02, at the project.

Pangolin chairman of the board Leon Daniels said, "The geophysical models available to Pangolin strongly suggest the potential for discovering additional very large kimberlites in the Tsabong North project area."

The company expects to start further work soon, with seven additional holes laid out for core drilling to determine the final size of the Magi-kimberlite.

Situated around 100km north of the town of Tsabong in south-western Botswana, the Tsabong North project is 1,545kmĀ² in size, features anomalous concentrations of kimberlite indicators, and has large geo-botanical features.
