The key findings and assumptions around the 27 May ASX Announcement concerning the Unicorn Project are being documented in a detailed report by Metallurgist Colin Seaborn. This report will pull together the findings and extensive test work conducted as part of the ongoing study since May 2014. The study was commissioned by the Board to clarify the level of accuracy for each aspect of the various studies undertaken as input into the 27 May ASX release. The market has previously been informed (latest as of 26 September 2014 in the company Annual Report) that a Prefeasibility Study (PFS) would be completed for the Unicorn Project by June 2015 – being part of the $9.9M Strategic Plan (ASX release 24 March 2014). A PFS is generally accepted as having a +/- 25% level of accuracy for the input data, this allows economic assessments to be made of projects within this level of confidence. The previous reporting around the confidence level (accuracy) of the various studies has been confusing, firstly being referred to as an industry standard PFS (Prefeasibility Study) in the March 24 2014 ASX release, then as a Project Study in the 2015 March 31 Quarterly Report and finally as a Project Definition Study (PDS) in the 27 May release. The Unicorn Project PFS Update report seeks to identify where each key aspect of the project is with respect to the desired PFS level of accuracy.

Upper Murray Goldfield – Regional Porphyry Stream Sediment Survey

Results for the Quarter: Regional stream sediment sampling conducted in the remote SE exploration area of Dart Mining’s tenement package (Figure 1) has been completed and initial interpretation carried out. The broad-scale stream sediment sampling program (Figure 2) was designed to identify anomalous metals associated with gold and potential porphyry related mineralisation within previously un-explored regions. Figure 2 illustrates the dense soil and stream sediment sampling that has been carried out by previous explorers in the area and also highlights the absence of previous sampling in the SE sector.

Of the 42 catchments sampled during the program, 4 contained low level gold B ulk L each E xtractable G old (BLEG) anomalies and two possible low order porphyry signatures with a coincident Ag-As-Bi-CuW-Sn-Mo-Pb-Sb-U and Ag-As-Sb-Cu-Zn-Ni anomalism, both identified to the south of the Boebuck Quartz Diorite in EL5468. BLEG samples are collected from a number of locations across a small area in the creek and sieved to -2mm. The -2mm sieved samples are sent for static leach (ALS CN12) at a commercial laboratory. 2 -3 kg Stream Sediment samples are similarly collected at a number of locations in the creek over a small area and returned to base to be dried and sieved to -80# (Mesh). The -80# sample is sent for 42 element analysis (ALS ME-MS61). A stream sediment sample is collected approximately every 10km[2] to allow low order anomalies to be detected. Follow-up geological mapping is planned when winter track closure is lifted to the area to identify any associated alteration or visible mineralisation within the anomalies identified.

Donovan’s Prospect – Soil Survey

Results for the Quarter: Donovan’s Prospect lies 2.5 km north of the polymetallic (Cu, Ag, Sn, Zn, Pb and Au) Mammoth Porphyry Prospect (Figure 2). A targeted soil program within a 5 km x 5 km grid was established to test the validity of a base metals soil anomaly interpreted through soil sampling conducted by previous explorers, thought to have potential to represent patterns of alteration and metal zonation

expected to be developed above a buried intrusion (Figure 3). All soil samples are collected at the top of the B horizon (clay layer) and sieved to -2mm prior to analysis carried out using a pXRF unit back at base. Rock chips are collected over an area of outcrop (2 - 5m[2] ) as a representative sample or from chips evenly distributed across a defined sample interval. The samples are submitted for whole sample pulverization and 42 element analysis (ALS ME-MS61).

Interpretation of the results of both soil and rock chip geochemistry with prospect geological mapping suggest a structural link with the regional Saltpetre Gap fault zone (a regional NW dipping thrust fault) that may have developed narrow shears at right angles (normal) to the main fault trend. Evidence of sheared material and gossanous alteration / mineralisation with associated base metal anomalism flank the NW trending shear structures over 1000m along the interpreted strike (Northeast, Central and Western Anomalies – Figure 3). The base metal anomalies may be related to mineralizing fluids tapped by the Saltpetre Gap fault zone during periods of extension and emplacement of the Mammoth Porphyry, which is exposed some 2.5kms to the south. Previous drilling by Dart Mining has shown the Mammoth Porphyry continues at depth below the regional Saltpetre Gap fault zone, trending to the north below Donovan’s Hill (Figures 2 & 3). The metal signature shows a suite of distal metals, indicating the source of the mineralizing fluids is likely to be buried deeply below Donovan’s Hill or represents structural leakage of mineralizing fluids along shears. As such the Donovan’s geochemical target has been downgraded against other porphyry targets such as Morgan, Gentle Annie, Stacey’s, Copper Quarry and satellite anomalies to the Unicorn Porphyry.

Interpretation illustrates the potential structural links at right angles to the Saltpetre Gap Thrust (a regional fault zone) which intersects the northern surface extent of the mineralised Mammoth Porphyry, some 2.5 km south.

GOLD ASSET DEVELOPMENT PROJECTS

Leading up to the General Meeting of 18 June 2015, significant attention had been placed on the development of promotional presentation material to assist in the disposal or joint venture of porphyry and gold assets held by the company. Following the appointment of a new Board at the general meeting, the main focus of exploration has been on further work around the known gold prospects within the tenement package. The approved Mountain View Mining Licence (ML5559) and gold mineralisation identified at the Onslow Reefs prospect have received significant attention. Topography surveys using a differential GPS have been conducted to better define detailed topography and mining features in the prospect areas. This survey will allow scoping study mine design to begin, leading to a preliminary economic assessment over the Mt View area. Ongoing soil geochemistry is being extended north of the Mountain View Mining Licence to test the size of previously identified gold anomalies associated with historic workings.

At the Onslow Reefs, a small program of RC drilling is scheduled for the September Quarter under the approved work plan. The initial drilling is targeted at shallow mineralisation above the 60m adit level where previous chip sampling of the lode has identified high grade gold mineralisation. The length of the mineralised zone is not defined at depth and requires drill testing. The planned drilling will be the first to be conducted at the Onslow Reefs prospect and will identify any low grade halo to the reefs and the continuity of structure and grade of the lode between surface and approximately 60m depth. The initial drilling will assist in estimating the potential of the prospect to host economic mineralisation and determine if additional drilling is warranted to estimate a resource. Up to 500m of RC drilling is planned in a series of vertically and horizontally fanned holes from up to two drill pads.
