Lithoquest discovered kimberlite on its first drill program at the North Kimberley Diamond Project. Micro-diamonds were discovered from its first sampling program and a 3,000-grain sample was recovered from the second sampling program in 2018.


The 100% owned project covers 1,500 km2 and is located in the northern portion of the Kimberley Plateau, approximately 225 km from Kununurra. The Gibb River and Kalumburu Roads provide ground access to the project area from either Derby or Kununurra. Locally, the Plateau is flat-lying and characterized by escarpments and isolated mesas.

Key Highlights

Lithoquest has developed compelling evidence that a field of diamond bearing volcanic pipes, called kimberlites, exists on its 100% owned North Kimberley Diamond Project. In 2018 the company discovered kimberlite in its first drill program, confirming the prospective nature of the project.

Key highlights of the project include the following:

  • 100% ownership with no royalties
  • Discovery of kimberlite in maiden drill program (2018)
  • Apparent (weathered) kimberlite boulders with high-interest chemical compositions have been discovered in four widely spaced locations. The boulders are thought to be derived from local sources.
  • Gem quality diamonds have been recovered from documented stream samples throughout the area, including a 1.73 ct diamond
  • The project can be accessed by a seasonal road and is located on tide-water
  • Heritage Protection Agreement in place with Traditional Owners
  • 2019 priority targets are indicated in red.

  • Core from Target 1804, drilled in September 2018

Target 1804

Kimberlite was discovered at target 1804 in 2018 during the Company’s maiden drill program on the North Kimberley Diamond Project. The target is defined by coincident magnetic and gravity anomalies as well as indicator minerals, including one diamond, recovered in historical* loam and stream samples. The kimberlite breccia is characterised by xenoliths derived from the local volcanic and sedimentary sequence.

The textures observed in the kimberlite and results from ground geophysical surveys over target 1804 suggest the occurrence is a pipe; however, additional drilling and petrographic work will be required to definitively determine the geometry and nature of the body.

Target 0702

Target 702 is defined by an occurrence of apparent (weathered) kimberlite boulders from which diamonds and indicator minerals with high-interest chemical compositions have been recovered.
Locating the source of the apparent kimberlite boulders is a high priority for Lithoquest Diamonds. Work completed at the target in 2018 included ground geophysical surveys, loam sampling as well as the collection of surface and sub-surface rock samples. All samples have been submitted for laboratory analysis and results are expected in Q4, 2018.

Target 1605

Target 1605 is a 200m x 80m topographic high that is adjacent to a NE structure feature. The surrounding area is largely sandstone, while the feature is characterized by red-brown pisolitic soils and ferruginous rock float. The float has fragmental textures and samples reported pyrope garnet and picroilmenite.
