Officer Basin

The Officer Basin

Strategic Elements is backing a major mineral hunt targeting rocks in remote Western Deserts, long ignored for their mineral potential.

The Company believes that certain areas of “Permian” aged rocks in the Great Victoria and Gibson deserts of the Officer Basin have excellent potential for a style of base metal deposits more commonly known in Germany and Poland.

The Officer Project is the first project developed in collaboration with world leading geologist Dr Franco Pirajno, who has been involved with several copper discoveries.

Ilkurlka Project

The Ilkurlka Project is one of three separate projects in the Officer Basin with unexplained buried magnetic ring features.

Meteorite impact structure expert Andrew Glikson proposed that the magnetic rings and other characteristics are indicative of a potential meteorite impact structure.

Other scientists suggest that the magnetic rings represent an igneous ring complex.

Ilkurlka is therefore prospective for:

  1. Ilkurlka is situated within a large shear zone named the Lasseter Shear Zone and adjacent to the continent-wide Mundrabilla Fault which runs north- south through the project area.
    These potentially provide a plumbing system for gold-bearing fluids.
  2. Hydrothermal zinc-copper-lead-(gold)- (uranium) mineralization related to a meteorite impact.
  3. Magmatic nickel-copper-PGE massive sulphide mineralization associated with a buried mafic – ultramafic intrusion.

Gold Anomaly

There is a significant gold in soil anomaly with peak value of 119ppb that has been identified from historical CRA diamond exploration at the Ilkurlka project in the Officer Basin.

Gold in soil values of 10.8 ppb, 14.2 ppb, 24.3 ppb, 24.5ppb, 28ppb, 32.4ppb, 51.7ppb and 119ppb were all recorded from within the area of the circular magnetic ring features of the Ilkurlka project.

The anomalous gold in soil is open in numerous directions and have been generated on wide spaced lines that are up to 1km apart, so there is much scope for better definition with extended infill and sampling.


In the mid 1990’s, WMC conducted diamond exploration 280km to the SW in the Tropicana area and detected a 10ppb -30ppb gold anomaly in soil. They reported “a number of minor gold anomalies up to 32ppb but none were deemed worthy of follow up”. These gold anomalies in soil were finally followed up by AngloAshanti in 2005 and led to the discovery of a new type of gold deposit, the +6,0000,000 ounce Tropicana gold deposit.

In light of the Tropicana Gold Deposit discovery via a 10ppb ‐ 30ppb Au soil anomaly, the 10ppb -119ppb Au in soil samples at Ilkurlka warrant prioritization of a gold-focused, surface geochemical program utilizing modern technologies and methodologies across the Ilkurlka Project area.

Ilkurlka Project Geology

Little is known about the geology of the area. Published geological map sheets of Wanna (SH52-02) and Vernon (SH52-01) contain annotations stating that geology in most of the areas covered are inferred, due to a lack of outcrop, together with a lack of field mapping work.

There has been no exploration drilling except for shallow mineral sands. No gold assays were taken. The stratigraphic BMR Wanna 1 hole was drilled in in the eastern section of the extended Ilkurlka Permit Application area to a total depth of 154m and ended in Paterson Formation.

Further Work

The 1999 CRA surface sampling was located around small magnetic anomalies identified for diamond potential and was not targeted for gold.

Follow up in-fill sampling will be specifically targeted for gold.

The Company has lodged a further 200 km2 of ground around the existing Ilkurlka project. Most of the project area remains totally unexplored with no historical soil sampling at all. The orientation, extent and significance of the gold mineralisation can only be determined with follow-up infill soil sampling of the historic regional soil anomalies and will be conducted as soon as possible.

Lennis Project

100% owned Maria Resources Pty Ltd has been awarded drill funding under the WA Government Exploration Incentive Scheme (EIS) for the Lennis Project in the western Officer Basin.

Magnetic geophysical data over the Lennis Project reveals a buried circular 7km diameter magnetic ring anomaly with a complex magnetic central core. This feature is potentially caused by a meteorite impact or igneous ring complex. Gravity geophysical data shows a distinctive, strong gravity high potentially related to a buried intrusive body located within the magnetic ring feature.

Maria Resources has been advised by the Department of Mines and Petroleum that the Lennis Project has successfully been awarded EIS funding after a competitive process with independent peer-review assessment.

Under the EIS, funds committed by Maria Resources towards the approved drill program will be matched with approx. $140,000 from the Western Australian Government.

Meteorite impact structure expert Andrew Glikson has posed the magnetic rings and other characteristics are indicative of a potential meteorite impact structure. Other scientists propose the magnetic rings represent an igneous ring complex. Lennis is therefore prospective for:

  1. Hydrothermal zinc-copper-lead-(gold)-(uranium) mineralization related to a meteorite impact.
  2. Magmatic nickel-copper-PGE massive sulphide mineralization associated with a buried mafic – ultramafic intrusion.

Existing gravity coverage at Lennis is wide spaced and an infill ground based gravity survey will be conducted to generate more detail on the gravity anomaly prior to drilling. It is intended that this survey will be conducted in the last quarter of 2017 with drilling to follow in early 2018 after all approvals have been received.

Maria Resources thanks the WA Government for its support and considers the grant of EIS funds to be indicative of the quality of the Lennis Project and the technical work conducted to date. The EIS co-funded drilling programme preferentially funds high quality, technical and economically based projects that promote new exploration concepts and are assessed by a panel on the basis of geoscientific and exploration targeting merit.
