Last year, the explorer found three diamondiferous kimberlite bodies within its vast exploration permit, named White, Black and Grey Wolf along with three kimberlite dykes.
Tests from 409.3kg of kimberlite from these new discoveries yielded 1,032 diamonds.

On Tuesday, the firm said preliminary results from esker sampling (sand and gravel remnants from the end of the ice age) highlighted at least three separate areas away from the known kimberlites, which show diamond indicator minerals.
Arctic said that "strong evidence suggests there are many more kimberlites to be found".
Encouragingly, Arctic said that esker samples near the known kimberlites "light" up with diamond indicator minerals. A similar anomaly occurs in an esker system 20km to the north east of the Wolf kimberlites, it said, and two other anomalies occurs 20km and 40km SSE (south south east) of the Wolf kimberlites respectively.
These four new areas will be followed up by closer spaced esker sampling, till sampling and will allow the company to focus planned airborne geophysical surveys, it said in a statement.
Meanwhile, geophysics and testing magnetic anomalies with an excavator at Timantti has now begun and results are expected within three to four weeks and will be reported as received.
Kimberlites with significant diamonds will be drill tested to determine size, and promising magnetic anomalies that could not be trenched will also be drill tested, the firm said.
