Environmental Impact Assessments and Mining Licence Applications – INCA, Tubas and Shiyela
Reptile Uranium Namibia Ltd (RUN) submitted Environmental Impact Assessment reports (EIA’s) to the Ministry of Environment and Tourism (MET) for the INCA and the Tubas Red Sand deposit areas (See Figure 1).
The EIA for the INCA deposit incorporates an environmental assessment for an open pit mine producing uranium and iron bearing ore of up to 2.5 million tonnes per annum which could result in the production of up to 2.5 Mlbs per annum U3O8, depending on project economics. It includes a process plant which could be utilised to chemically leach output from a Schauenburg hydrocyclone plant processing ore from the TRS deposit.
The EIA for the Tubas Red Sand deposit includes an environmental assessment for a shallow, free dig open pit mine producing uranium ore which will be upgraded by physical beneficiation (utilising the Schauenburg Process) to produce a high grade uranium rich paste amenable to acid or alkali leaching. The strategy is to produce a loaded resin intermediate product to could be sold to one of Namibia’s existing uranium producers.
RUN also submitted two Mining Licence Applications (MLA’s) to the Namibian Ministry of Mines and Energy. The applications were made on behalf of two of its 95% owned subsidiaries, INCA Mining (Pty) Ltd and TRS Mining Namibia (Pty) Ltd, under section 91 of the Minerals (Prospecting and Mining) Act of 1992.
A local Namibian company, Oponona Investments (Pty) Ltd, holds the remaining 5% of both entities.

RUN also submitted an MLA for Shiyela to the Namibian Ministry of Mines and Energy on 11 December 2011 (Figure 1). The application was made on behalf of a 95% DYL owned subsidiary, Shiyela Iron (Pty) Ltd under section 91 of the Minerals (Prospecting and Mining) Act of 1992. Oponona Investments (Pty) Ltd, a local Namibian company and RUN’s empowerment partner, holds the remaining 5%.
OMAHOLA PROJECT
Ongolo Alaskite Deposit
The Ongolo Alaskite Deposit JORC Compliant Resource was tripled to 20.5 Mt at 400 ppm U3O8 for 18 Mlbs U3O8 at a 250 ppm cut-off. The updated Indicated and Inferred Mineral Resource estimate was completed by Coffey Mining Pty Ltd (Perth) (Coffey). The new Resource represents an increase of 11.8 Mlbs of contained U3O8 compared to the May 2011 estimate. Approximately 73% of the 18 Mlb resource (13.2Mlbs) is classified in the Indicated category.
Ongolo was discovered by RUN in April 2010, approximately 12 kilometres NE of its INCA deposit (Figure 2). The maiden JORC Resource estimate for the deposit, based on 2010 drill data, was completed by Coffey and announced on 12 May 2011. The 2011 drill data was incorporated with the 2010 data giving a drillhole database for the estimation of 342 RC and 18 diamond holes totalling 71,081 metres. The drillholes were typically drilled at 60° towards 135°.
Grades within the mineralised zones for U3O8 were estimated by block Multiple Indicator Kriging (MIK). A Selective Mining Unit (SMU) of 5 x 5 x 3 metres was selected to simulate the anticipated mining parameters. SMU corrections were applied to the estimate to report expected recoverable resources.
By count, approximately 20% of the composites used in the estimate were sourced from chemical data and 80% from factored radiometric assays. However, as the high-grade regions of the drilling were typically character assayed by chemical methods, approximately 65% of the resource metal endowment was sourced from chemical assay methods. The deposit is still open along strike and down-dip in some areas.
MS7 Alaskite Deposit
The MS7 alaskite deposit, located approximately 2 kilometres to the west of Ongolo (Figure 2), was discovered in May 2011 and an interim JORC Inferred Mineral Resource was prepared by Coffey in October 2011 based on drilling to mid-September. Subsequently a further 80 RC and 5 diamond holes for 14,766 metres were added to the resource database which now comprises 207 RC and 7 diamond drillholes for a total of 38,350 metres. This database was used by Coffey to update the Resource in December 2011, resulting in it being more than doubled to 5.4 Mt at 470 ppm U3O8 for 5.6 Mlbs U3O8 at a 250 ppm cut-off.
Approximately 60% of the 5.6 Mlbs resource (3.3 Mlbs) is classified in the Indicated category. The higher grade Inferred Resource, at 540 ppm U3O8, reflects recent high grade intersections that are open to depth (to the north) and which will be targeted for infill and extensional drilling in the New Year.
The main mineralised zone now extends about 800 metres along the strike and is up to 400 metres wide and is open to depth below 200 metres. Drill spacing is 50 x 50 metres to 100 x 100 metres.
Although Ordinary Kriging (OK) was used initially for MS7, the updated resource estimate was calculated using the MIK method which was also used in for the Ongolo deposit upgrade.
Approximately 30% of the composites used in the MIK estimate were chemical XRF-Fusion assays and 70% from factored radiometric data. Importantly, approximately 60% of the total metal endowment of MS7 is underpinned by the chemical assays.
Drilling at MS7 intersected some of the highest grades encountered in our Alaskite exploration to date, including :
-
ALAR847 3 metres at 5,531 ppm U3O8 from 172 metres including 1 metre at 1.15% U3O8 from 173 metres
-
ALAR886 33 metres at 2,207 ppm U3O8 from 39 metres and 69 metres at 1,229 ppm U3O8 from 92 metres
-
ALAR793 6 metres at 2,303 ppm U3O8 from 265 metres

Omahola Project Updated Resource Statement
Conceptually the Omahola project comprises a processing plant located close to the Ongolo Alaskite deposit treating a blend of primary ore from the Ongolo and MS7 Alaskite deposits and the INCA uraniferous magnetite deposit (Figure 2). The TRS deposit, which was historically a part of the Omahola Project, has now been excluded as a result of the decision to investigate a standalone operation supplying uranium loaded resin to one or the two existing uranium producers in Namibia.

Figure 2: Ongolo-MS7-INCA Trend Showing Resource Outlines at 250 ppm U3O8 Cut-Off
The Project’s Resource base, which will be predominantly mineable by open pit methods, now totals 40.7 Mt at an average grade of 413 ppm U3O8 for 37 Mlbs U3O8 (Table 1). Resources at both MS7 and Ongolo are increasing through ongoing exploration success which is expected to continue in 2012.
Coffey commenced high level pit optimisation exercises at the end of 2011 on both the Ongolo and MS7 deposits using forecast operating costs to test the economics of both and thereby enhance the effectiveness of the next phase of exploration drilling.

Next Steps
An Environmental Impact Assessment of the Ongolo-MS7 area will commence in 2012 once there has been sufficient resource definition and the likely location of the processing plant has been selected. Limited sterilisation drilling has already been conducted.
SHIYELA IRON PROJECT
Maiden JORC Resource Estimate
Golder Associates Pty Ltd (Perth) completed a maiden JORC Mineral Resource estimate for Shiyela in December, returning an Inferred Mineral Resource estimate of 78.7 Mt at 18.88% Fe at 10% Davis Tube Recovery (DTR) cut-off for the M62 and M63 magnetite deposits with an average DTR magnetite content of 16.17% (Appendix 3). The database included 202 RC holes for 36,277 metres and 8 diamond holes for 2,196 metres drilled over the two deposits M62 and M63, whilst a total of 141 holes were used in generating the wire frame models for both deposits. DTR results from 1,699 four metre composite samples were used in the estimate (Figures 3 and 4).

Process Flowsheet
A minesite-located process plant will be designed to produce a final product at 80% passing -150 micron (μ) using a wet Low Intensity Magnetic Separation (LIMS) circuit. It is expected that the basic flowsheet will consist of a two-stage crushing circuit followed by High Pressure Grinding Rolls and inter-stage magnetic separation producing a 400 μ pre-concentrate feeding a milling/magnetic separation circuit to produce the final -150 μ product.
ProMet commenced the Scoping Study for the Shiyela Iron Project during the quarter based on mine and plant producing 2 Mtpa concentrate. The report was nearing completion by the end of the year and results will be announced early in 2012.
Forward Programme
A large diameter diamond drilling programme (PQ – 85 mm) is being undertaken to provide core for the next phase of metallurgical testwork to be conducted by ProMet, as a part of a planned accelerated Feasibility Study. The programme will comprise at least 3 holes at both M62 and M63 for approximately 1,000 metres of PQ core to generate some 16 tonnes of mineralised material.
Subject to the outcome of the Scoping Study and the availability of funding for the project a programme of RC and diamond drilling to target lateral and depth extensions to the M62 and M63 deposits will be conducted in 2012. In addition the 20 kilometre long magnetic anomalism that hosts M62 will be explored by RC drilling to outline additional resource potential.

Leichhardt Project
The Leichhardt Project comprises EPM 14367 Spider (Altona JV – DYL 80%) and EPM 18127 - Leichhardt River (DYL 100%). Following a desk top study reviewing the uranium potential of the region a reconnaissance programme was undertaken to validate the generated targets. The reconnaissance programme continued during the quarter at the Spider Project and at the Wild Dog area of the Prospector EPM (Figure 6), where known historical prospects and previously unidentified radiometric and magnetic targets were investigated. Numerous uranium occurrences have been identified for follow-up work.
The project area lies immediately north of the high grade Anderson’s Lode (14 Mlbs U3O8 at 1,430 ppm U3O8) along a strongly developed North-South structural corridor which hosts mineralisation at Andersons and the Big Dip and A25 prospects.

Officer Project
Following negotiations with the Traditional Owners and the Central Land council (CLC) the Officer Hills Deed for Exploration covering Exploration Licence Applications 25097, 25155, 25177, 25212, 27140, 27141 and 27334 was executed on 30 November 2011. In addition a Deed incorporating granted EL 10223 with the above applications into one Deed was executed on 1 December 2011.
The Deed for Exploration for the Officer Project (Figure 7) will be lodged with Department of Resources following return from stamp duty assessment by NT Revenue and grant of the licences are expected by the end of February 2012.
Lake Mackay Project
The CLC advised DYL of the outcome of a late September meeting for the Lake Mackay Project tenements (Figure 7). Access to a number of tenements has been vetoed and an exploration exclusion zone has been declared around the lake shore. Further consultation with Traditional Owners is required prior to a formal notice with respect to access to the tenements for uranium exploration.
Napperby Project
Results from the recent AEM Survey over the Napperby Project areas have been received. The data shows a deep (± 100 metres) conductive zone on the west side of Lake Lewis (Figure 8), which is considered to be a possible target channel. In the shallow data set (30 metres) the conductive lake sediments mask the channel position.

In addition the new data has outlined a potential ‘deep channel’ to the north of the Napperby resource (Figure 8). A fence of shallow auger (15 metre) holes were drilled across the channel by Uranerz in 1980, but no uranium anomalies were identified. The channel will be tested by a deep drill programme in the June quarter.
