Report for the Quarter Update Ended 30 September 2015

16 October 2015

ASX Code: DTM

Key Projects:

Unicorn Porphyry: Mo-Cu-Ag

Copper Quarry: Cu-Au Gentle Annie: Cu

Morgan Porphyry: Mo-Ag-Au

Fairley’s: Au Mountain View: Au

Investment Data: Shares on issue: 243,257,892 Unlisted options: 15,473,048

Substantial Shareholders: Top 20 Holdings: 51.13%

Corporate Update

  • A review of the Company’s direction and strategy was implemented over the course of the period.

  • Further study around the immediate viability of the Mt Unicorn Mo-Cu-Ag project was undertaken and completed.

  • Conclusions drawn from the Mt Unicorn project study indicate that for the time being economic risks around further work and development are too great to proceed with any substantial expenditure and development at this time.

  • The board continues to seek potential joint venture partners for the Mt Unicorn project which may materialize over time as and when a recovery in the Mo price is seen as sustainable.

  • The board adopted a recommendation to pursue the acquisition and development of more Au projects that fit predetermined criteria. These criteria are limited by Geographic location, Project size (large and small), as well as Financial capacity to execute such ventures.

  • Development work on Mt View progressed as the company seeks to bring the project into production.

  • On-going Au opportunities and negotiations are the Company’s primary focus for the immediate future.

  • At the end of the quarter the Company’s cash position stood at approximately $683,000.

Unicorn Project – Study Update

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.

GOLD ASSET DEVELOPMENT UPDATE

Following the appointment of a new Board at the general meeting (18 June 2015), 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 and Fairley’s prospects have been further reviewed with the aim of assessing the viability of each prospect for gold production (Figure 1).

MOUNTAIN VIEW PROJECT

Scoping level mine design and costing aspects of the proposed Mountain View open pit have been completed with bulk sampling now necessary to complete detailed metallurgical studies. A work plan has been submitted to carry out the bulk sampling program, with approvals expected early in the next quarter. The bulk sampling will provide recovery details and indicate the best toll treatment facility for the ore style, this will also allow negotiations to be finalized on treatment costs and allow completion of a preliminary economic assessment of the Mountain View mineralisation.

A program of targeted infill soil geochemistry using a portable XRF (pXRF) has recently been completed. The infill soil traverses test a 1.2km long area to the north of the previously conducted Mountain View gold soil grid (Figure 2). The results have been very encouraging, confirming previous board scale soil geochemistry lines that showed anomalous gold and arsenic in soils around the historic workings of the New Discovery mine, some 1.3km north of the Mountain View mine. The recent infill soil survey has now identified four arsenic in soil anomalies up to 350m in length from insitu B horizon soil sampling, the soil traverses are spaced at 20m along the strike of mineralisation and each sample is collected at 5m intervals across strike (Figure 2). This soil survey highlights the likely repetition of gold mineralised sulphide lenses; the most northern arsenic anomaly (350m in length) corresponds with the historic New Discovery lens. Previous rock chip sampling (See ASX DTM 12 March 2009) has shown up to 1.5m @ 5.38 g/t Au within the historic workings. The potential for the repetition of mineralised pods along the strike of the Brown’s Creek fault had already been established to the south of the Mountain View mine with further historic workings located at the South Golden Bell, also showing corresponding elevated arsenic in soil. Discreet arsenic in soil anomalies along the Mountain View line are now evident over some 2 km of strike length with six zones currently identified that are worthy of first pass shallow drilling.

FAIRLEY’S PROJECT

A mineralisation Report is currently being prepared for the Fairley’s Project using all available drill and rock chip data to model the currently tested near surface mineralisation. The mineralisation report will accompany an application for the renewal of the Buckland EL4724 (Figure 1). The completed pXRF soil sample traverses at Fairley’s have highlighted the growing scope of the system to host multiple outcropping mineralised zones over the completed 800m of the survey grid (Figure 3) as well as the deeper potential already identified in the previous diamond drilling. The two additional soil traverses at the far south of the grid have again shown some very exciting results with highly anomalous soil arsenic levels up to 450m in width, the highest arsenic in soil levels within this southern zone may correspond with a new Central Shear (identified during early exploration mapping) and the strike extension of the western lines toward the western end of the traverses. The new central zone and the previously identified anomalies clearly warrant drill testing and require the preparation of a new work plan for drilling and drill access track construction. The mineralisation report and EL4724 (Buckland) renewal application will be the focus of the next Quarter, with additional soil traverses and work plan preparation for further drilling planned for the March 2016 Quarter.

ONSLOW REEFS PROSPECT

A small program of RC drilling that was scheduled for the September Quarter at the Onslow Reefs was deferred pending the outcome of detailed metallurgical test work on the Mountain View mineralisation and completion of the scoping level economic viability study. Outcomes of the Mountain View study are likely to be directly applicable to the Onslow Reefs system with a similar silica / sulphide mineralisation style.
