Unicorn Project Reborn in Game Changing Turnaround

Detailed metallurgical test work, analysis, and efficient application of conventional, standard industry practice and design has demonstrated the technical achievability of saleable Molybdenum (Mo) and Copper (Cu) products from the Unicorn deposit(see ASX Release “Unicorn Project

Page 1

Dart Mining NL

Report for Quarter Ended 30 September 2014 | 27 October 2014

Reborn” - 31 July 2014). This means a turnaround for the Unicorn project and greatly enhances its development to production prospects (see ASX Release “Unicorn in Game Changing Turnaround” -11 September 2014). Of particular note is that:

  • Saleable Metal (both Mo, and Cu) is able to be recovered from the Oxide portion of the resource;

  • Saleable concentrates are able to be produced from across the entire Unicorn deposit resource;

  • Previous Zinc separation issues have been resolved and overcome;

  • Proven (conventional, standard industry practice) processes have been applied, so reducing technological and commercial risk; and

  • A whole-of-deposit, draft process flowsheet has been developed which will be further detailed and refined as feasibility studies and analyses progress.

Highly experienced metallurgist, Dr. Colin Seaborne, who designed, analysed, and directed all the foregoing test work and studies, using two independent laboratories, and who achieved the Unicorn turnaround, has been appointed Dart’s PFS Manager.

During the Quarter, Dart produced a new annual production schedule (for internal valuation purposes) of current Unicorn resources based on the newly defined metallurgical parameters that now allow:

  • Incorporation (and recovery) of significant metal content from the Oxide resource material (previously designated as ‘waste’) into the Mill/Process Plant Feed stream; and

  • Recovery, with industry standard ease, of Molybdenum, Copper, Silver (and Zinc) from across the range of fresh resource material within the deposit.

Regional Exploration

Regional exploration at Fairley’s, Onslow Reefs and Onslow South prospects continues to expand the geochemically anomalous zones. Greenfields soil traverses tested a series of targets (Figure 1). An exploration review by Dart’s Strategic Advisor - Exploration, Dave Royle, has highlighted the potential of the porphyry and gold prospects and refined the exploration strategy. Efforts in the forthcoming Quarter will be focused on the drilling underway at Unicorn. Drilling at Copper Quarry, Gentle Annie, Fairley’s and Onslow Reefs is planned at the end of the Unicorn drill programme. Soil geochemistry is planned for Fairley’s, Onslow, Mountain View South, Scorodite Ridge and Donovan’s.

Fairley’s Prospect

RESULTS FOR THE QUARTER: Geochemical sampling has extended arsenic anomalism associated with the main Fairley’s line and defined two new trends to the north and the west (Figure 2). The Fairley’s line remains open to the south but has been closed to the north. The new line to the north is offset from the Fairley’s line and remains open to the north and south. Four adits have been found on this northern line. The new line to the west has not previously been worked. The line has been closed at the northern end but remains open to the south. The soil samples were collected from the top of the clay layer (B Horizon) using an auger and analysed by pXRF in the field enabling sampling to follow the elevated arsenic readings.

Figure 2. Colour coded arsenic (As) in soil (pXRF) at the Fairley’s prospect over colour digital elevation model. Earlier 2007 Dart Mining laboratory soil results for arsenic are included. New lines of anomalism have been identified to the west and north of the main Fairley’s line.

TARGETS & PLANS: Dart Mining now understands Fairley’s to be a series of sub-parallel faults with internal gold shoots. Ongoing geochemical sampling will continue to locate and delineate the distribution of the shoots at surface. Drilling is planned at Fairley’s during the forthcoming field season.

ABOUT FAIRLEY’S PROSPECT: Dart Mining was the first to recognise a disseminated style of gold mineralisation within the historic Buckland Goldfield. Dart Mining conducted soil geochemistry over the main Fairley’s workings in 2007 (Figure 2) and drilled the first scout holes into the prospect of 11 RC and 2 diamond holes in 2008. The best drill intercept was 21 m @ 1.41 g/t gold and chip sampling of historic workings returned 12.5m @ 6.62 g/t and 10m @ 2.99 g/t gold

Onslow Reefs and Onslow South Prospects

RESULTS FOR THE QUARTER : An expanded soil grid was established to test for previously unidentified mineralisation surrounding the Onslow Reefs and Onslow South prospects (Figure 3). Infill of new anomalous zones has begun and the Onslow South trend has been extended further northwards. This trend is over 400 m long and open north and south. A shallow shaft and an adit were found adjacent to the arsenic anomalism at Onslow ‘A’. No workings have been found at the other anomalies identified. The soil samples were collected from the top of the clay layer (B Horizon) using an auger and analysed by pXRF in the field enabling sampling (and assaying) to follow the elevated arsenic readings.

TARGETS & PLANS: Dart Mining now understands that multiple reefs occur in the Onslow vicinity. Drilling is planned at Onslow Reefs and Onslow South during the forthcoming field season.

ABOUT ONSLOW REEFS AND ONLSOW SOUTH PROSPECTS: The historic Onslow Reef workings occur as a small isolated cluster 8km south of Unicorn and show narrow quartz-sulphide lodes with true widths between 0.7 and 1.5m where mapped in the main adit level. Historic records describe further workings at Onslow South and to the north of Onslow Reefs, although the latter has yet to be located.

Other soil surveys conducted during the September Quarter

Follow up soil geochemistry at Empress South failed to expand the copper anomalism previously reported [see DTM: ASX Release 30 June 2014] or find new areas of mineralisation. Soil traverses at Bullocky Creek were conducted to try to find the source of the gold at the top of a series of alluvial workings where there are historic reports of nuggets up to 8 oz. However, the geochemical results failed to delineate a source. A soil traverse at Sylvester’s, a structural target, encountered weak arsenic mineralisation (up to 34 ppm) but will not be followed up.

Copper Quarry Prospect

RESULTS FOR THE QUARTER: New exposure at Copper Quarry has revealed sheeted veins sets (Figure 4) and extensive disseminated pyrite (+ chalcopyrite + chalcocite) mineralisation consistent with phyllic alteration above a mineralised porphyry.

==> picture [452 x 264] intentionally omitted <==

Figure 4. The face at Copper Quarry showing sets of sheeted veins (upright and dipping downwards towards the right of the photo) and iron staining, in part from weathering of disseminated sulphides.

TARGETS & PLANS: Dart Mining believes Copper Quarry is the surface expression of a mineralised porphyry and has an exploration model to guide testing this system at depth (Figure 5). Two drill holes are planned to test for alteration changes with depth and to allow for downhole geophysics or deeper drilling if successful.

ABOUT COPPER QUARRY PROSPECT: The Copper Quarry prospect shows highly anomalous copper over 400m from soil sampling. Variable composition of cross-cutting igneous rocks at the surface suggest a complex intrusive history. Dart Mining has completed a 50m x 50m soil grid and infill sampling and geological mapping during the initial exploration phases.
