Lithoquest discovered kimberlite on its first drill program at the North Kimberley Diamond Project. Micro-diamonds were also recovered from its first sampling program.

 

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:

  • 1,500km2 project area 100% owned by Lithoquest
  • 20 priority target areas defined for a two-phase field program (2019)
  • Discovery of kimberlite in maiden drill program (2018)
  • Kimberlite boulders identified over a wide area of the project
  • Gem quality diamonds recovered from documented stream samples throughout the area, including a 1.73 ct diamond. 3 micro-diamonds found in a 10kg sample (2018)
  • one microdiamond found in a sample taken in a separate area (2018)
  • Project is accessed by a seasonal road and is located on tide-water
  • 2019 Targets

  • Core from Target 1804, drilled in September 2018

  • LDI.V mineral tenements, Western Australia

NEW 2019 Targets Section

20 high priority targets have been identified on the North Kimberley Diamond Project for follow up during the 2019 field season. Three criteria were used to select the priority target areas: 1) the presence of Kimberlite Indicator Minerals (KIMs), 2) geophysical anomalies, and 3) areas of interest resulting from a geospatial analysis designed to detect kimberlites. Three target areas met each of the criteria and are considered the highest priority. A majority of the remaining 17 target areas met at least two of the three criteria.

The objective of the 2019 field program is to investigate and prioritize the target areas, followed by drill testing of the most promising kimberlite targets. Field work to define drill targets is expected to commence in early June and will include geologic mapping, prospecting, geophysical surveying and KIM sampling. Drilling is expected to begin in August.

  • 1827 Target Area is characterised by the following criteria: 1) The presence of diamond and abundant KIMs, 2) Coincident magnetic and conductivity anomalies 3) A very high priority geospatial target

  • 1827 Target Area is characterised by the following criteria: 1) The presence of diamond and abundant KIMs, 2) Coincident magnetic and conductivity anomalies 3) A very high priority geospatial target

  • 1826 Target Area is characterised by the following criteria: 1) The presence of abundant KIM’s 2) A discreet magnetic low anomaly

  • 1805 Target Area is characterised by the following criteria: 1) The presence of diamond and abundant KIM’s 2) A wide, linear magnetic low anomaly 3) A very high priority target from geospatial analysis

  • 1902 Target Area is characterised by the following criteria: Large, coincident magnetic and conductivity anomalies

  • 1902 Target Area is characterised by the following criteria: Large, coincident magnetic and conductivity anomalies

  • 1828 Target Area is characterised by the following criteria: 1) The presence of abundant KIM’s 2) A very high priority geospatial target


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. The kimberlite breccia is characterised by xenoliths derived from the local volcanic and sedimentary sequence. Laboratory age dating analysis shows that 1804 is 600Ma younger than its nearest neighbours, the Ashmore and Seppelt kimberlite fields.

Laboratory analysis concludes that 1804 displays textures and physical properties typically associated with kimberlite pipes. Additional drilling and petrographic work will be required to definitively determine the geometry and nature of the body. The Company believes its understanding of the characteristics of target 1804 will provide guidance to further kimberlite discoveries in 2019.

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.
