Kango Iron Ore Project - Exploration Target

Emerging West Africa focussed iron ore company Volta Mining Limited (“Volta Mining”) (ASX: VTM) is pleased to to advise that a recently commissioned report “Kango Exploration Target Estimate”, dated May 2013 by SRK Consulting (Australasia) Pty Ltd and associates (Fathom Geophysics) (“SRK”) confirms that its Kango Iron Ore Project (the “Project”) in Gabon is prospective for itabirite mineralisation, with three (3) large scale magnetic anomalies identified within the licence area, interpreted to reflect favourable zones for iron mineralisation.

Key Points » Kango Iron Ore Project prospective for itabirite-hosted iron mineralisation

» Historical drilling (2009) of 15 holes confirmed the presence of several itabirite zones

» Hematite enrichment of the itabirite recognised in some of the surface rock chip samples with grades ranging between 39% Fe and 61% Fe

» Three (3) large scale magnetic anomalies identified and interpreted to reflect favourable zones for iron mineralisation over a 40km strike length

» Kango Project lies approximately 25km from the multi-user Trans–Gabon Railway (“TGR”) and approximately 125km from the port of Owendo – Figure 1.

SRK considers the Kango Iron Ore Project to be early in the exploration cycle, however, limited drilling and surface sampling has confirmed the presence of itabirite in both magnetite and hematite enriched forms, with grades reported to range between 39% Fe and 61% Fe.

SRK’s estimate of the Exploration Target, based on several phases of unconstrained geophysical inversion modelling and geological interpretation, is 98Mt to 750Mt of material grading between 30% Fe to 45% Fe, with possible grades up to 60% Fe in places. It should be noted that the potential quality and grade of the Exploration Target is conceptual in nature, that there has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimate of a Mineral Resource.

Managing Director of Volta Mining, David Sumich said, “The Exploration Target for our Kango Iron Ore Project presents another exciting opportunity for Volta Mining.

Exploration Target SRK’s estimates for the Exploration Target are based on several phases of unconstrained geophysical modelling and geological interpretations, with the understanding that the distribution of magnetic material may help define the distribution of iron rich zones within the Project area.

Geophysical inversions were conducted using variations of the traditional total magnetic intensity methods in order to counteract issues of remnant magnetism observed within the aeromagnetic data. An inversion process using the analytical signal was used (RTP VIAS), and an acceptable fit to the observed data was achieved. Isosurfaces reflecting the distribution of the magnetic material within the Project area were created for further interpretation.

ASX Announcement12 June 2013

Additional geophysical image processing was conducted in order to highlight structural features with the Project area. Based on the inversion modelling, processed images and geological datasets, distribution of a potential iron rich geophysical unit was interpreted across a 40km strike length of the Kango licence. Three dimensional modelling of this unit was undertaken in order to define its lateral and subsurface extents, and to provide a geologically and geometrically realistic context to the magnetic anomaly.

A range of analysis considering the array of potential iron grades, thicknesses, unit tonnages and magnetic susceptibilities were tested in order to estimate the Exploration Target. A number of assumptions were required in order to undertake the range analysis in consideration of a geologically reasonable scenario for iron mineralisation. These were:

» Volumes were depth limited to 150m below surface, as this is considered a reasonable first-pass minable depth;

» The interpreted geophysical unit was assumed to host itabirite, with the interpreted mineralised volumes limited to this domain;

» This geophysical unit was assumed to only be mineralised within zones of elevated magnetic susceptibility (>0.04 SI); and

» Due to large variation of ranges for the magnetic inversion results, zones representing hematite enrichment could not be reasonably assessed.

Results of the range analysis are summarised below – Table 1.

Fe Grade (%) Tonnes (t) Unit Width (m) Magnetic Susceptibility (SI)

Min Case 30 98,000,000 5 0.07

Mid Case 45 750,000,000 15 0.06

Max Case 60 7000,000,000 40 0.04

Table 1: Summary of range analysis and resultant estimated Exploration Target ranges

Given the uncertainties associated with the geophysical modelling, SRK recommended that an Exploration Target for the Kango Iron Ore Project be considered at the lower end of the range; being 98Mt to 750Mt of material grading between 30% Fe to 45% Fe, with possible grades up to 60% Fe in places.

Exploration Work Completed Between 2009 and 2013 Core Mining Gabon SARL (“Core Mining”) identified a large magnetic anomaly extending over 40km along an ENE strike within the aeromagnetic datasets. Field work conducted by Core Mining as well as previous sampling by the Gabon Mines Department identified itabirite within the licence, with upgrading in some areas to hematite-itabirite. Several of these itabirite samples were found to correlate well with the identified anomalous magnetic zone.

In 2009, SRK conducted an exploration assessment of the Kango Iron Ore Project licence area and confirmed itabirite in outcrops and evidence of hematite enriched itabirite close to the western boundary of the licence – Figure 2.

ASX Announcement12 June 2013

Figure 2: Volta Mining’s Kango Iron Ore Project, Gabon - selected examples of hematite-enriched itabirite historically sampled (provided by Core Mining)

A limited drilling programme of 15 drill holes was undertaken by Core Mining, targeting the magnetic anomaly – Appendix B. Several zones of itabirite were intersected during the drilling campaign indicating a strong magnetic response in approximately 50% of the identified zones. Itabirite zones were found to be typically thin, ranging from 1 – 24 metres in width.

Further Work The large range of the Exploration Target strongly reflects the very long strike length of the observed magnetic feature, which extends over 40km within the licence. It is unlikely that itabirite mineralisation would extend continuously along the entirety of this feature. Further drilling and geological mapping along the extents of this feature is required in order to better correlate observed magnetic bodies with geological features. Such validation work will include, subject to obtained results:

» Geophysical surveys including closer spaced aeromagnetic data (<500m grid spacing) and possibly gravity data;

» Geological and structural mapping of the itabirite to resolve the true nature and 3D distribution of the observed magnetic features across the licence

» Collection of surface rock samples for the whole rock iron suite assay and the determination of petrophysical rock properties; and

» Approximately ten (10) drill holes, for a preliminary total of 1,500m of drilling, to drill test in the Exploration Target area, and specifically, the clearly elevated magnetic signatures and the presence of itabirite samples within proximity of these zones – Figure 3.

Volta Mining has an experienced field team in Gabon and intends to commence ground field work in the coming months. The collection of airborne data and drilling will be subject to the availability of third party contractors to undertake the work, the results obtained from the geological and structural mapping, and assay results.

Data aggregation methods

• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.

• Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

• The assumptions used for any reporting of metal equivalent values should be clearly stated.

• No assay results were available for historical drilling. Grades used within the study were based from rock sampling assays with values quoted by Volta on their website ranging between 39-61% (Volta Mining, April 2013);

Relationship between mineralisation widths and intercept lengths

• These relationships are particularly important in the reporting of Exploration Results.

• If the geometry of the mineralisation with respect to the drillhole angle is known, its nature should be reported.

• The true subsurface nature of the ore body is as yet not fully understood and as such drillhole widths are reported only as down-hole widths. True widths not known

• If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’).

Diagrams • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drillhole collar locations and appropriate sectional views.

• Figure 1: Locations of Surface Samples and Drill Holes Collars within Kango Project • Refer to SRK (2013) for additional spacial data

Balanced reporting • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

• Full list of surface exploration results presented in SRK (2013)

Other substantive exploration data

• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test

• Several phases of geophysical modeling and geological interpretation of aeromagnetic data were conducted in order to define an Exploration Target for the Kango Project. Details are outlined in detail within the SRK (2013) and outlined as follows:

• Magnetic Data: Aeromagnetic data was collected as part of a regional survey over the Kango Project with a line spacing of 500m

• Magnetic Inversions: Unconstrained 3D magnetic inversion modelling was conducted

of the aeromagnetic data • Geophysical Imaging: Reduced to Pole and Structural Detection Images were

produced from aeromagnetic datasets. • Geological Interpretations: Geological interpretation of and 3D geological modelling

was conducted. • Exploration Target Estimates: A range analysis considering:

Mid Case 45 750,000,000 15

Max Case 60 7,000,000,000 40

• It should be noted that these Exploration Target ranges are reliant on a number of assumptions and interpretations of an unconstrained magnetic inversion. As such, SRK recommends that an Exploration Target for the Kango Project be considered at the lower end of the range (i.e. the Min and Mid cases), being 98Mt to 750Mt of material grading between 30 to 45% Fe, with possible grades of up to 60% Fe in places.

Further work • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).

• Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

• Geological mapping of the Kango Project area has been proposed at a scale of 1:25,000
