Mt Cecelia Project



WWI’s Mt Cecelia Project is located approximately 150km ENE of Marble Bar, 150km NW of Telfer Mine, and 120km NNW of Nifty mine (aerial distance).  The region is considered one of the country’s most prominent addresses for mineral exploration with several joint venture agreements being reached since RIO’s WINU discovery, approximately 70km E of Mt Cecelia, and AIM Listed Greatland Gold’s Haverion project E of Telfer.

RIO’s extensive 2018 pegging campaign included EL’s covering over 60% of Mt Cecelia’s border with its local interest increased through the $6m farm-in & joint venture agreement with Carawine Resources (ASX:CWX) to explore CWX’s Baton project which sits on Mt Cecelia’s SE boundary.

The Company signed an access deed with RIO Tinto Limited (“RIO”) in October 2019 and RIO submitted a Program of Works in January 2020 to build tracks on the Mt Cecelia tenement area to access their surrounding EL’s.  RIO’s activity is an indication of the prospectivity of West Wits Mt Cecelia project and improves the Group’s tenement access with the construction of tracks.

Mt Cecelia’s adjoins Carawine’s Baton project to the south east which was included in RIO’s farm-in agreement and also encompasses the Vines Fault. RIO EL applications on tenements adjacent to Mt Cecelia to the north and east were granted in October 2019.

Mid-tier miner, IGO Limited (ASX:IGO) has also demonstrated strong interest in the region having completed a $15m earn-in agreement with Encounter Resources (ASX:ENR) at ENR’s Yeneena project.  IGO’s interest extends via the execution of a $32m Joint Venture term sheet in June 2020 with Metals X (ASX:MTX) at MTX’s Paterson Exploration Project (PEP) but excludes the historically significant Nifty mine.  Both Yeneena, PEP and Nifty are located to the south of WWI’s Mt Cecelia project along the Vines Fault which was a focus of the PGN desktop review and the upcoming field work.

Exploration Program

Exploration Program

The HEM survey follows West Wits’ local exploration team’s initial reconnaissance trip in July 2020 which determined access and supply stations for future exploration as well as provide observations of geological outcropping and other features.  The field trip identified large areas of the tenement to be under sand cover, a common feature of the Paterson Province, which was a key motivator in commissioning the HEM survey.

SkyTEM is a world leader in the delivery of airborne electromagnetic (AEM), magnetic (Mag) and DTM data used in the determination of the value of mineral exploration, hydrological or geotechnical projects.

SkyTEM recently completed the helicopter-borne electromagnetic survey covering the entire 225km2 tenement area, flying 1,205kms survey lines at 200m spacing and 30-50m above ground level.

West Wits engaged Southern Geoscience Consultants (SGC) to provide geophysical expertise, having worked closely with SkyTEM previously and being associated with successful discoveries in the Paterson Province over the past 20 years.

The preliminary data was received by SGC on a daily basis to independently assess the data quality / coherence (QA/QC) and check for localised potential bedrock anomalism.  Five areas with potential anomalism were identified and resulted in a further 12 infill survey lines being completed, totalling an additional 36-line kms, to reduce the survey line spacing to 100m in these localised zones (Figure 2).  The infill flying was able to further refine and highlight the central locations for defined anomalies.

The collected data will contribute critical information to our project reports and models and will primarily be utilised to:

  • Determine the presence and depth of conductive bodies at depth
  • Obtain detailed 3D lithological information, including faulting and folding, where present
  • Provide geophysical input into the geological structural model over the area; and
  • Assist in target definition for exploration drilling


Additional information that may be obtained from the HEM survey data includes:

  • Delineation of geological boundaries and thickness variations of the underlying lithology, possibly identifying deeper seated zones of mineralisation and outlining of possible mineralisation traps; and
  • Assist in improved understanding of major geological structures, which may act as barriers or possible conduits to mineralisation.


Final data processing efforts have commenced at SKYTEM with data deliverables due in late October.  Final interpretation and enhanced processing will then be undertaken by SGC which is expected to be completed in 4Q 2020, identifying the high priority targets and guiding the next stage of exploration, which will be advanced in the Paterson Province region’s subsequent field season that commences in April 2021.


Desktop Study Review

PGN Geoscience were engaged by the Company to perform a detailed Lithostructural desktop study to assist in developing new exploration models for target generation at WWI’s Mt Cecelia project and to provide a context to existing/known mineralisation occurrences.

The study generated an improved geological map and the revised understanding which has significant implications for future exploration programs, primarily from the identification of a folded and faulted, banded-ironstone, felsic intrusive complex that is highly prospective for orogenic gold.

The new geological interpretation and resultant map introduces a considerably more complex geology than the currently available public geological map and includes a new interpretation for the Vines Fault a major structural element in the Paterson.

BIF–Hosted Orogenic Gold Target

The initial interpretation suggests that a folded banded-iron sequence is juxtaposed by a series of steep structures. The publicly available airborne magnetics further suggests a series of demagnetised zones internal to the BIF. The hypothesis is that these are prospective for orogenic gold mineralising systems.  The resultant new geological interpretation has resolved a new architecture and consequently new litho-structural framework for the Mt Cecelia project area within E45/5045, the central west area location is highly prospective for orogenic BIF hosted gold.

Polymetalic VMS & Manganese Targets

The study found, the Kylena Formation and Jeerinah Formation are prospective for VMS deposits. Both of which occur in significant volumes within the tenement area. These formations represent classic bimodal volcanic sequences and as such, present a significant opportunity and considerable spatial extent for exploration within the WWI tenure.

Through the extrapolation and resultant understanding from developing a district-scale exploration litho-structural map, Manganese deposits such as those locally related to the Baramine series of deposits ~8km to the south-west are hosted within a form-surface related to the synformally folded sequence of Pinjian Chert Breccia units.
