Project Description

The Leviathan Project covers a large approximately 4 km in diameter gravity anomaly.

The Leviathan gravity anomaly has no previous exploration as it was not visible until new gravity data became available in 2019. The anomaly is surrounded by a suspected field of up to 100 volcanic pipes reported by Gunson Resources and DeBeers in 2003. It is considered prospective for copper-gold-rare earths mineralisation related to volcano-intrusive complexes.

The Leviathan project is located approximately 140 km to the south of the Company’s Behemoth Project, within an area where there is no Native Title Determined or Native Title Claim made. This removes the requirement for Aboriginal Land Access & Mineral Exploration Agreements and Aboriginal Heritage Surveys to be conducted. Therefore, the only remaining major regulatory hurdle prior to drilling at Leviathan is a Programme of Works from the Western Australian government to use mechanised equipment within the project. This is a highly beneficial feature of the Leviathan Project.

Recent Work

A small number of the volcanic pipes were drilled by DeBeers in diamond exploration. No diamonds were discovered, but historical drill records viewed by the Company contained multiple references to disseminated sulphides. As sulphides can be related to copper-gold mineralisation the Company accessed historical drill cores stored in the Western Australian drill core library.

Recent petrographic analysis of historical drill core WSH003 by Dr Franco Pirajno confirmed a lamprophyre (volcanic pipe) that contained tuff material with fragments of galena (lead sulphide) and chalcopyrite (copper sulphide). Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption and then compacted into solid rock.

Maria Resources has applied for drilling funds for the Leviathan copper-gold-rare earths project from the Exploration Incentive Scheme, a competitive program that supports innovative exploration drilling projects.

Companies awarded funding under the Exploration Incentive Scheme will be notified in November 2019

Upcoming Work

Maria Resources has commenced a ground-based gravity survey program, 3D inversion and forward modelling at the Leviathan Project. The gravity survey is designed to follow up the gravity high anomaly identified at the Leviathan Project.

More detailed gravity applicable for modelling the Leviathan anomaly is currently being conducted by Atlas Geophysics and consists of a total of 349 gravity stations at 400m spacing with two infill lines running north-south at 100m spacing.

3D inversion and forward modelling by Southern Geoscience Consultants will aid in the identification of the approximate depth of the gravity anomaly, targets and structural zones for further follow up work.

Leviathan Project Geology

In geology, lamprophyre volcanic pipes are associated with alkaline and carbonatite intrusions. The Leviathan gravity anomaly is postulated to be the top of an alkaline intrusion and potential associated carbonatite surrounded by the lamprophyre volcanic pipes identified in De Beers drill cores and magnetic data. It is considered prospective for copper-gold-rare earths mineralisation related to volcano-intrusive complexes.

Carbonatites consist of more than 50% carbonate material that are highly prospective for copper-gold-rare earths. The approx. 3km diameter Mt Weld carbonatite in Western Australia is one of the world’s richest sources of rare earths. Other alkaline intrusions and carbonatites are associated with copper, gold and niobium.
