The North Kimberley Diamond Project covers an area of 1,000 km2 in a highly prospective region of Western Australia. Lithoquest owns 100% of the Project.

 

The Project is located in the northern portion of the Kimberley Plateau, approximately 225 km fromĀ 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

Sampling conducted in 2007 and 2017 has produced results that suggest the discovery of new kimberlites on the property is likely. Rocks discovered on the property have textures typical of weathered kimberlite. The chemical composition of indicator minerals recovered from the rocks suggests conditions favourable for diamond formation and preservation. Follow-up work is required to confirm the presence of kimberlite and to obtain material for further testing. Key highlights of the project include the following:

  • The area is prospective for economic diamond deposits – the Ellendale and Argyle diamond mines are associated with the Kimberley Plateau and bulk sample tests were conducted on the local Ashmore and Seppelt kimberlites (Seppelt has reported a grade of 2.25 cts/t*)
  • The property is a significant, contiguous land package covering an area over 100,000 Ha in size. To date, 6 kimberlite pipes and 8 kimberlite dykes have been identified on the property. All are associated with structural features.
  • Rock samples collected from 2 locations in 2017 exhibit textures similar to weathered kimberlite. The rock samples were collected from target areas where sampling in 2008 produced high priority kimberlite indicator minerals with no known source.
  • Gem quality macro diamonds have been recovered from documented stream samples throughout the area, including a 1.73 ct diamond.
  • The area can be accessed by road.

Lithoquest has planned a program of work for 2017/2018. The program will comprise both field and office components. Office work will involve desktop studies to develop and identify additional priority targets for follow-up. Field programs will consist of drilling on high priority targets as well as geophysical surveying and prospecting over areas of interest.

Target 0702

Target 1702 is a 3 Ha sized oblate geomorphic feature associated with a NE trending structure. The local bedrock is Proterozoic aged sandstone overlying volcanics. Rock samples from exposed bedrock in a weathered drainage at 1702 display porphyritic textures similar in appearance to olivine macrocryst kimberlite. Float in the area is common and exhibits silicified skeletal or fragmental textures. Samples from the feature yielded pyrope garnet, chrome diopside, picroilmenite and chromite. The presence of G10D garnets and the geothermobarometry determined from chrome diopside demonstrates the minerals formed in the diamond stability field.


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.
