Perth, Australia – 19 August 2024 | Litchfield Minerals Limited (ASX: LMS) ("Litchfield" or "the Company") is pleased to announce the discovery of significant gravity anomalies at the Dumunzi and Patmungala targets within the Mt Doreen Project, located in the West Arunta region of the Northern Territory. These findings have been identified through recent ground gravity surveys and three-dimensional inversion modelling, adding substantial value to the ongoing exploration efforts in this highly prospective area.
Highlights:
-
Discovery of Multiple Density Anomalies: Ground gravity surveys conducted at the Dumunzi and Patmungala targets have revealed multiple significant density anomalies. These anomalies, particularly at Dumunzi, are situated within an east-northeast dilatational jog, a structural feature that could create favourable conditions for the formation of mineralized systems.
-
Dumuzni Target Insights: The Dumunzi target has shown a complex structural-magmatic zone, with inversion modelling suggesting a possible alkaline intrusion or carbonatite affinity. The identified dense anomalies are broadly coincident with a reversely magnetised linear feature, further indicating the potential for significant mineral deposition in this area.
-
Patmungala Target Developments: At Patmungala, the gravity survey has identified several shallow density anomalies. While no direct relationship has been established between these anomalies and the deep-seated magnetic source known as "Megalith", their presence suggests a possible metallogenic connection, which warrants further investigation.
-
Next Steps for Exploration: Litchfield plans to conduct further geochemical sampling and shallow drilling at these targets to assess the mineral fertility and explore the potential for economically viable mineral deposits.
Matthew Pustahya, Managing Director & CEO of Litchfield Minerals, commented: “I’m extremely pleased with the results of the gravity survey and 3D inversion modelling for both the Patmungula and Dumunzi areas. These datasets have provided our team with valuable insights into these regions.
I’m particularly excited about the Dumunzi data, which is revealing a relationship between dense gravity anomalies and a reversed magnetised structure interpreted as a dilatational jog, which are areas that provide the physical space needed for mineral deposition where mineral rich fluids can flow and precipitate.
While it’s too early to draw any conclusions and further work is needed to assess the mineral fertility, it’s encouraging given the similarities between our location in the West Arunta and some of the geology of the various Carbonatites being discovered in the region such as WA1’s Luni and Encounter Resources Emily Niobium/ Rare Earth deposits.
In the Patmungula zone, while we’ve identified dense anomalies - one of which crosses a major structure, there doesn’t appear to be a direct relationship with the large magnetic body we’ve named “Megalith” at depth. The team had hoped to see a clear connection between the two to guide our potential drilling of this large, deep magnetic body.
With that said, I'm excited about the dense anomalies identified by the gravity survey in the western section of the Patmungula area. These anomalies align across structure to the known copper, lead, and fluorite mineralized zones to the southeast within Patmungula. The company still has more work ahead to fully assess the exploration potential of this area."
