BUSINESS REVIEW
OMAHOLA PROJECT
MS7 Resource Update
An updated JORC Code Compliant Resource for the MS7 Alaskite deposit was completed by CSA Global (UK) Pty Ltd. Contained U3O8 was increased by 18% (1 Mlbs) with 65% of the resource classified as Measured and a further 15% in the Indicated category. The resource estimate (Table 1), at 6.8 Mt at 437 ppm U3O8 for 6.6 Mlbs U3O8 at a 250 ppm cut-off is an increase of 1.0 Mlbs U3O8 over the 2011 estimate, taking the Omahola Project Resource base to 39.6 Mt at an average grade of 437 ppm U3O8 for 38 Mlbs U3O8 at a 250 ppm cut-off. Figure 1 shows the Project’s resource outlines whilst Figure 2 shows the MS7 resource outline at the 250 ppm cut-off together with the 2012 drill collars.
Table 1: MS7 JORC Compliant Mineral Resource Estimate – November 2012

Grade estimation was completed using MIK. The portion of the MRE classified as Measured is based on drill holes located on an approximately 50x25 metre grid. Indicated and Inferred are based on drill holes located on an approximately 50x50 metre (and wider) grid. The MRE utilises all available drill hole sampling data collected over the history of the Project. Data used for the MRE comprised a combination of Fusion XRF assay values and down-hole gamma U3O8 equivalent grades. All figures are in metric tonnes based on a Dry Bulk Density of 2.65 t/m[3] . M&I is Measured + Indicated. Significant figures do not imply an added level of precision after all MRE tabulations. Conversion factor kilograms to pounds - 2.2046. No Ore Reserves have been estimated.

Figure 2: MS7 Deposit – 2012 Drill Programme and Footwall Discovery Location
Uranium mineralisation at MS7 is hosted by alaskitic granite, which occurs as voluminous masses and sheeted intrusive dykes, within the meta-sedimentary Khan Formation. The uraniferous alaskites at the MS7 Project are located in a large fold structure comprised of Khan-Rössing Formation marble and calc-silicates with localised large garnet clinopyroxene / magnetite skarns.
The major marble footwall unit is shown in Figure 3, and mineralized (>75 ppm U3O8 alaskite envelope) in Figure 4.

Figure 4: MS7 Mineralised Alaskite Shell and Footwall Marble Unit
The drill programme resulted in an improved alaskite interpretation and increased the reliability of the geological model as well as improving grade confidence in some areas. The repeatability of the previous results with the infill drilling has added to the increased confidence in the estimate.
Ongolo Alaskite Deposit
Fusion XRF chemical assay results from the ‘south-west’ sector of the Ongolo deposit (Figure 5) were received confirming high grade zones and deeper intercepts which are open to depth. The planned Ongolo drill programme comprises approximately 120 holes for 25,000 metres. It is anticipated that the programme will be completed early in 2013 with an updated resource estimate due in February 2013.
Selected significant results from the quarter’s drilling programme include:
o |
ALAR1453 | 6 | metres at | 448 ppm U3O8from 57 metres |
|---|---|---|---|---|
o |
ALAR1402 | 6 | metres at | 496 ppm U3O8from 63 metres |

o |
ALAR1470 | 9 | metres at | 401 ppm U3O8from 120 metres |
o |
ALAR1484 | 19 | metres at | 808 ppm U3O8from 143 metres |

and | 3 | metres at | 1,127 ppm U3O8from 203 metres |
o |
ALAR1490 | 8 | metres at | 1,280 ppm U3O8from 150 metres |
o |
ALAR1499 | 6 | metres at | 749 ppm U3O8from 176 metres |
o |
ALAR1417 | 6 | metres at | 491 ppm U3O8from 217 metres |
| and | 25 | metres at | 497 ppm U3O8from 245 metres | |
o |
ALAR1415 | 18 | metres at | 406 ppm U3O8from 227 metres |
Particularly encouraging is that the drilling is confirming contiguous zones of mineralised alaskite open to depth such as intersected in holes such as ALAR 1400, 1415 and 1417 (Figure 5) in the ‘south-west’ Ongolo Area. In addition, continuity of mineralisation from section to section will improve the resource category.

Figure 5: Ongolo Deposit and Regional Reconnaissance Drill Programmes
Tubas Sand Project
An 8,000 metre detail resource drill programme on the Tubas Sand Project commenced in November 2012, targeting the conversion of JORC Code Inferred Mineral Resource estimates to higher levels of confidence in two priority areas (Figure 6). Planning is also underway for a pre-feasibility study which will include additional metallurgical testwork although this is contingent on a successful outcome of the drill programme.
The 2012 Inferred Mineral Resource for the deposit totals 87 Mt at 148 ppm U3O8 for 28.4 Mlbs U3O8 at a 70 ppm U3O8 cut-off comprising a carnotite bearing red sand that is amenable to upgrading via physical beneficiation.
The drill programme should be completed early in 2013, with drillhole spacing of 100 by 50 metre in the initial phase and then to 50 by 50 with close-off areas at 25 metre spacing on the 50 metre lines. Holes will mostly be shallow (<15 metre deep) based on mineralisation in previously drilled surrounding holes. All holes are being gamma logged within the rods and collars surveyed by DGPS. Samples are collected every metre and those from anomalous zones are analysed by pressed powder XRF in RUN’s Swakopmund laboratory with regular check samples being sent to third party laboratories.
In preparation for the planned PFS for the Project, the following programmes will also be undertaken in addition to the RC drilling:
-
Metallurgical testwork.
-
Bulk sampling to establish a representative bulk density for the deposit.
-
Gangue acid consumption testwork assays.
-
Survey control to establish an accurate topographic surface over the deposit.

Mining Licence
The Ministry of Mines and Energy of the Republic of Namibia (MME) issued a Notice of Preparedness to Grant a Mining Licence for the Project (Figure 7). The standard terms and conditions contained within the notice of preparedness were accepted and therefore, in accordance with Namibia’s Minerals (Prospecting and Mining) Act, 1992, it is expected that the Minister of Mines will now direct the Mining Commissioner to issue a Mining Licence to the company.
JORC Resource Update
An updated resource estimate was produced by Golder Associates Pty Ltd (Golder) (Perth) during the quarter. The December 2011 Inferred Mineral Resource was increased by 36.4 Mt to 115.1 Mt at an enhanced grade of 19.5% Fe.
The magnetite-dominant M62 deposit, capable of producing a 68% Fe product, has an Indicated and Inferred Resource of 44.7 Mt at 17.3% Fe and overall weight recovery of 16.37%. A satellite deposit to M62, known as M62R (Figure 7), has an Inferred Resource of 9.3 Mt at 16.3% Fe with an overall weight recovery of 17.4%.
The mixed magnetite-hematite M63 deposit, capable of producing a 63.8% Fe product, has an Indicated and Inferred Resource of 61.2 Mt at 21.6% Fe with an overall weight recovery of 28.9%.
The resource update was based on results obtained from a PQ core drilling campaign completed early in 2012 and additional metallurgical testwork; Davis Tube Recovery (DTR) and Davis Tube Concentrate (DTC) assays on the magnetite domain samples and Fusion X-ray Fluorescence (XRF) assays on hematite domain samples. As a result, almost 80% of the M62 magnetite deposit is in the Indicated category, whilst for M63 approximately 10% of the mineralisation has been classified as Indicated. A summary of the Shiyela Mineral Resource is given in Appendix 3.

Metallurgical Testwork Programme
A large diameter diamond drilling programme (PQ – 85 mm) was completed early in 2012 to provide core for the next phase of metallurgical testwork, which was overseen by Mintrex Pty Ltd (Mintrex), as a part of an updated Scoping Study. The programme comprised approximately 1,000 metres of PQ core and generated some 16 tonnes of mineralised material from M62 and M63.
A series of metallurgical testwork programmes were conducted on the core, including testwork on the magnetite, recovery of hematite from magnetite tailings and recovery of hematite from a predominant hematite source. The additional testwork provided the information required for an improved flowsheet design (Figure 8) to allow the recovery of both magnetite and hematite. It is expected that up to 85% of the contained Fe will be recovered by the new plant design.
The process flow plant will initially recover iron by dry magnetic separation (at a 3 millimetre grind size) at two fields strengths followed by a relatively coarse grind to 80% passing 250 micron followed by low intensity magnetic separation (LIMS) and low strength wet high intensity magnetic separation (WHIMS). The magnetite can be recovered to a concentrate grade of 68% Fe and the hematite to a grade of 61% Fe, demonstrated on a range of samples from 5% Fe in feed up to 40% Fe with varying proportions of magnetite and hematite.
Testwork demonstrated that grade could be adjusted by slight changes in grind size which was therefore designed into the capability of the plant. On this basis a 68% Fe product has been adopted as the nominal grade of the magnetite after grinding to 80% passing 250 micron.
The plant has a 1200 gauss collection of magnetite followed by a 7000 gauss dry magnetic separation and 3000 gauss WHIMS in a wet section – it has been assumed that all magnetite measured by the Davis Tube (3000 gauss) will be collected in the plant – i.e. 100% yield.
Hematite testwork looked at hematite recovery from magnetite tailings and hematite recovery from ores classed as hematite. A programme conducted to test the possible process route involved testing three sizes

for dry magnetic separation (DMS) and medium intensity dry magnetic separation (MIMS) and testing the dry concentrate at four different sizes using heavy liquid and tabling at three different gauss levels.
As a result of these tests the final process selection was for a grind of 80% passing 250 micron and a WHIMS gauss of 3000 gauss, which gave a concentrate grade of 63.8% (mixed magnetite and hematite) and a 92.9% Fe yield to concentrate. A conservative estimate was thus made of an 85% Fe yield and with 68% Fe from the magnetite and 61% Fe from the hematite. The hematite grade was 62.3% Fe at the target conditions and magnetite from the same sample was 68.6% Fe.

Scoping Study Update
Mintrex Pty Ltd completed a scoping study for the Shiyela Iron Project, with economically encouraging results. The capital cost estimate for a mine producing 2 Mtpa of concentrate and at a confidence level of +/30% was US$367 million whilst operating costs were estimated at US$63.20 per tonne of concentrate FOB. Plant capital cost is US$207.3 million with the remainder made up of mining-related capex and infrastructure.
Three types of ore can be processed by the plant design, magnetite, magnetite with significant hematite tails, and hematite with minor magnetite tails.
The Scoping Study was based on the results obtained from a comprehensive three-stage testwork programme which allowed the development of the process flowsheet and preliminary plant design (see Figure 8).
The positive outcome of the scoping study will allow the company to pursue its previously announced partner strategy for the project.

AUSTRALIA
Divestment of Australian Exploration Portfolio
DYL announced in June that it had decided to divest its portfolio of early stage exploration assets in Australia to allow it to focus on its advanced stage projects in Namibia. The Australian portfolio consists of projects located in both Queensland and the Northern Territory and includes the 7.4 Mlb of JORC compliant resources at the Napperby Deposit. DYL appointed Patersons Securities Limited (Patersons) to investigate a trade sale, merger or spin-off of the portfolio which may lead to a full or partial divestment of its interest in these projects. Patersons identified a number of target companies that were approached to gauge interest and discussions with these are ongoing. Interest picked up after the announcement of the process to allow uranium mining in Queensland.
CORPORATE
Financial
DYL completed the Quarter with cash and liquid assets of $7.2 million at 31 December 2012.
During the quarter 5,500,000 performance share rights were issued and 920,000 lapsed according to their terms and conditions.
Capital Raising and Share Issues
DYL successfully completed the placement of shortfall shares from the previous quarter’s non-renounceable entitlement issue. The placement of 154,761,905 ordinary fully paid shares at 4.2 cents per share for $6.5 million was made to a specialist mining fund, Laurium L.P. (‘Laurium’). As a result of the placement Laurium became a substantial shareholder with 9.96% of the Company’s expanded share capital.
On 24 December 2012 DYL issued 129,333,333 to Raptor Partners Limited (‘Raptor’) and remitted $100,000 in consideration for the termination of an Earnout Agreement between the two parties.. The Earnout Agreement required DYL to pay Raptor1.5% of the in-ground value of each identified uranium oxide Mineral Resource within the RUN Tenements upon completion of a definitive feasibility study and in respect of which a decision to mine is made.
Board Appointment
DYL announced the appointment of Mr Christophe Urtel, Laurium’s Senior Fund Advisor, to the Board as a Non-executive Director. Mr Urtel has more than 13 years’ industry experience and prior to joining Liberum Capital in 2011 he was an Executive Director in J.P.Morgan’s Principal Investment franchise in London responsible for natural resources investments.
