Project Location
The Goe Fantro Iron Ore project is located in Liberia, West Africa and is approximately 15km from the coast and part way between Monrovia and the port of Buchanan. The project exploration license is governed by a Mineral Development Agreement (“MDA”) and is 100% owned by Cavalla Resources Ltd.

Project Description
The project hosts a JORC compliant inferred resource of 568mt, including 101mt Direct Shipping Ore (“DSO”) averaging 57.2% Fe at a cut-off grade of 50% Fe. A Scoping Study was conducted on the project in 2009 that indicated an output of 5 million tonnes per annum with a mine life of 20 years. Optimisation studies have commenced to determine the optimal transport logistics for the project. Significant resource upside potential exists at Goe Fantro, as the initial resource is located to the south of the deposit. Higher grade ores were found to the north of the deposit in the “Firestone” area where limited drilling has been undertaken to date.

The project has excellent infrastructure options, being 70km from the port of Buchanan with existing tarred roads. It’s located within 7km of the navigable Farmington River which is 21km from the coast offering a possible barging and transhipment solution.

The project’s high quality ore and proximity of infrastructure options sets Goe Fantro apart from its peers enabling a fast track, low cost route to production.

Mineral Resource Estimate:
The Goe Fantro project consists of the Goe, Goe North and Firestone ranges in the county of Grand Bassa.

The global mineral resource estimate (using JORC 2012 guidelines) for Goe, Goe North and Firestone as at May 2014 at a cut-off grade of 20% or 30% Fe (for low grade mineralisation) and 50% Fe (DSO) is summarised as:

DSO Inferred 101 Mt at 57% Fe at a 50% Fe cut-off
JORC- compliant resource 466 Mt at 57.2% Fe ranging from 20% Fe to 50% Fe

 

Project Geology
The stratigraphy of the Goe Fantro project consists of three formations tectonically interleaved with basement gneiss and amphibolite. The area to the east of the regional normal fault is interpreted to be underlain by the formation in the centre of the project area which is mainly quartzites and schists with minor silicate facies BIF. At Goe North it consists of a moderate west to southwest dipping sequence of quartz sericite schist, underlain by itabirite and an intercalated unit of quartz sericite schist and itabirite. There were isolated DSO grades intersected in the itabirite; however these appeared to be relatively narrow and discontinuous.

The first anomaly consists of schists, quartzites and itabarite and is normally poorly mineralised or barren. The second iron formation, which is bound by faults, consists of quartz-muscovite schists overlain by oxide facies itabarite. This unit hosts the iron ore mineralisation at Goe and Goe North and forms the main northwest-southeast ridge. The third anomaly is a complex series of quartz-muscovite schists, amphibolites and quartzites. This zone is sporadically mineralised.

The second iron formation near the Goe Range consists of a folded northwest trending synclinorium and is bound to the northeast by a normal fault and to the west by a thrust fault. The itabirite consists of Fe-bearing minerals martite-goethite with lesser haematite. Typically higher grade friable itabirite is found within the oxidised zone and is interpreted to be formed by leaching of silica during the weathering process. The mineralisation terminates against a normal fault to the east and northeast and at the footwall contact of the itabirite unit with quartz sericite schist.

Firestone geology and mineralisation
The Firestone prospect is located in the northwest part of the project area. The geology is less structurally complex than Goe and Goe North and the area is underlain by a relatively simple northwest trending and southwest dipping sequence formation that overlies the basement granite gneiss.

Although the itabirite at Firestone is interpreted to be the same formation as at Goe and Goe North, it is more siliceous. The average iron content of fresh itaribite at Firestone is 26% Fe to 28% Fe versus 35% Fe to 36% Fe at Goe and Goe North. The content however is very similar which indicates a low amount of interbedded clay rich sediment within the itabirite at both areas.

The itabirite consists of Fe-bearing minerals martite-goethite with lesser haematite. Typically higher grade friable itabirite is found within the oxidised zone, interpreted to be formed by leaching of silica during the weathering process. Areas of higher grade DSO mineralisation defined by the 50% Fe grade shell typically occur along the crest and flanks of ridges underlain by itabirite. DSO mineralisation is thickest beneath the crest of ridges and may exceed 15m thick but pinches or wedges out along the flanks.

Geological Interpretation
At Goe and Goe North the DSO mineralisation extends approximately 3 000m north-south, with an average width of 200m and a variable depth between 50m and 200m. The deepest section lies towards the top of the ridge line at Goe and Goe North. Low grade itabirite is generally limited to a similar extent with some deeper extensions interpreted to 300m to 400m below surface at Goe North as a result of faulted blocks and some deeper drilling. Compact material is limited at Goe as the folded itabirite generally lies above the fresh weathering surface.

Goe Range geology and mineralisation
The host rock to mineralisation at Goe and Goe North is the second itabirite unit which, consists of Fe-bearing minerals martite-geothite with lesser haematite. Typically higher grade friable itabirite is found within the oxidised zone, interpreted to be formed by leaching of silica by the weathering process. The higher iron grades occur on the central syncline of a shallow south plunging synclinorium. Mineralisation terminates against a normal fault to the east and northeast and at a footwall contact of the itabirite unit to the west.

Work Program 2016/2017
The 2016/ 2017 work program will consist of infill drilling of the Goe and Firestone Ranges to enable the resource to be upgraded to the indicated or measured resource classification. In addition, metallurgical studies, density measurements and environmental and social studies will be expedited in order to complete a scoping study and subsequently a pre-feasibility/ feasibility study.

Initial exploration activities will include further drilling of approximately 2000 metres at Goe Fantro. The drilling program would seek to define the distribution and extent of any potential mineralisation.

Subject to the results of earlier activity, the work program for phase two is expected to comprise of the following;

Subject to the results of earlier activity, the work program for phase two is expected to comprise of the following;

  1. Phased drilling of any mineralisation defined at Firestone to delineate the ore body;
  2. Closer spaced drilling of Mt Goe and Goe North to allow generation of geology and structural models that may be used in resource modelling;
  3. Infill drilling for further resource definition.

Other activities may include;

  1. Commencement of scoping study and ESIA; and
  2. Commencement of DFS
