ASX QUARTERLY REPORT

FOR PERIOD ENDED 30TH JUNE 2013

Mt Thirsty Cobalt – Nickel Oxide Project - positive results continue …

Highlights

Further metallurgical test work, process development and financial modelling carried out by Consultants RMDSTEM during the quarter:

  • Agitated leach tests prove the ability of SO2 alone to extract ~80% Co and 25% Ni from Mt Thirsty ore in 4 to 5 hours with low Fe extraction and acid consumption.

  • Value adding by production of Ni-Co oxide chemicals from a Co-Ni hydroxide precipitate could have a premium of 15-20% above their LME metal values.

  • Revised Capex of $66.7-$68.5m for two 3000 tpd processing options including $20m for site infrastructure. Opex estimated at $5.53 to $5.75/lb Co.

  • Company name changed to Conico Ltd to reflect operational focus.

Metallurgical Testwork

Subsequent to the test work successfully completed last quarter consultants RMDSTEM were engaged to carry out the following additional tasks:

  • Conduct agitated Leach tests (5 large bottle roll tests) to prove the ability of SO2 to extract Cobalt from Mt Thirsty ore.

  • Demonstrate that that SO2 alone, as sulphurous acid, can extract the Cobalt and

  • Manganese.

  • Demonstrate that no sulphuric acid is needed to drive the process.

  • Demonstrate that only minimal iron needs to be released into solution.

  • Identify value-added products, assess the cost benefits and outline the process.

  • Conduct financial modelling for the recently proposed thickener and resin process flowsheet options (refer previous Quarterly report).

Agitated Leach Tests

  • A 10 kg split from a master bulk sample was selected at random. This was screened and crushed to pass a 1.0 mm screen, with a series of 1 kg subsamples derived from this sample.

  • The subsamples were placed into a dried 18L bottle fixed in a small cement mixer and a requisite amount of water added, the temperature adjusted, and SO2 injected at various rates.

  • Samples were extracted at the start, then at 10, 20, 40, 60, 90 and 120 minutes for four samples. These were carried out at various rates of SO2 injection, and at different temperatures.

  • The solids were screened to -300 μm, and -106 μm, and the three solids filtered, dried and assayed. These assays were used to compute a true head grade along with the Co, Ni, Mn, and Fe assays of the liquid samples that were taken.

  • The data from the first four tests was examined and it was concluded that more time and more water should be used to allow for more SO2 to be in the experiment.

  • A fifth experiment was run for four hours (or 240 minutes).

Test Results

Test results are summarised in Table 1 and graphs (Figure 2a & b) showing results obtained for Tests 3 and 4 are included below

.

RMDSTEM are of the opinion that if continued for another hour both Tests 3 and 4 should achieve 80% Co recovery with Fe release still controlled. Speciation tests indicate that the best possible recovery of Co is 87% (the portion tied up in Mn oxides) as the remainder is locked up in silicates and other minerals by stronger covalent bonds.

CONICO LTD

Report for June Quarter 2013

Based on the test results to date RMDSTEM concluded that provision of 4 to 5 hours of leaching capacity should suffice to give an average Co recovery of 80%. If the temperature is allowed to exceed 40[o] C the speed of the reaction will increase but so will the extraction of Fe which would dilute the final product.

Value Added Products

RMDSTEM were requested to identify potential value added products from Mt Thirsty Co -Ni hydroxide precipitates, assess their cost benefits and outline a recovery process. A production flow diagram (Figure 3) was designed to produce Ni and Co oxide chemicals which could have a 15 to 20% premium above their LME metal value.

Figure 3: Value Added Co and Ni Chemicals Production Flow Diagram

Financial Modelling

RMDSTEM carried out financial modelling based on two flowsheet options, Resin in Pulp and a Thickener Prewash (refer March Quarterly Report) using a throughput of 3000 tonnes per day. A deterministic sensitivity analysis was undertaken to examine risk and uncertainty.

Both flowsheet options were found to have similar Capex requirements of $68.5m (RIP) and $66.7m (Thickener) including 30% contingencies on plant and equipment and $20m for site infrastructure. Unit operating costs were estimated at $5.75/lb Co for the RIP option and $5.53/lb for the Thickener option.

The major external risk factors are exchange rate and cobalt price and the major internal factors cobalt head grade, payable cobalt and leach recovery rate.

Based on their recent testwork and results of their financial modelling RMDSTEM believe Mt Thirsty has good potential to be a low cost cobalt project. They recommend a detailed Pre- Feasibility study including large scale testing, process development and design.

CONICO LTD

Report for June Quarter 2013

Corporate

Approval was given for a change of company name from “Fission Energy Ltd” to “Conico Ltd” (ASX Code CNJ) at a general meeting held on 28[th] June. The new name now reflects the focus of the company’s operations on the Mt Thirsty Cobalt-Nickel project.

Mt Thirsty Project Details

The Mt Thirsty Cobalt –Nickel -Manganese oxide project covering an area of 47km[2] is located 20km north-northwest of Norseman in the southern goldfields of Western Australia, a well endowed nickel terrain (see Figure 1). Conico Ltd through its wholly owned subsidiary Meteore Metals Pty Ltd owns 50% of the project in joint venture with Barra Resources Limited. The Mt Thirsty deposit has the potential to emerge as a significant cobalt supplier. Recent metallurgical test work indicates that high recoveries of cobalt together with some nickel can be achieved through low temperature agitated leaching.

Mt Thirsty has a JORC (2004) compliant Indicated Resource of 16.6 million tonnes at 0.14% Cobalt, 0.60% Nickel and 0.98% Manganese and a JORC (2004) compliant Inferred Resource of 15.3 million tonnes at 0.11% Co, 0.51% Ni and 0.73% Mn over a length of 1.6 kilometres and a width of up to 850 metres.

As well as the Co-Ni oxide resource, the Mt Thirsty joint venture tenements have potential for nickel sulphide mineralisation at greater depth within the same ultramafic sequence which hosts the near surface oxide deposit. Intersections of nickel sulphides up to 4m down hole at 3.5% Ni were made by the joint venture in 2010.

***

The interpretations and conclusions reached in this report are based on current geological theory and the best evidence available to the authors at the time of writing. It is the nature of all scientific conclusions that they are founded on an assessment of probabilities and, however high these probabilities might be, they make no claim for complete certainty. Any economic decisions that might be taken on the basis of interpretations or conclusions contained in this report will therefore carry an element of risk.

The information in this announcement, insofar as it relates to other Mineral Exploration activities in Australia, is based on information compiled by Michael J Glasson and Robert N Smith, who are members of the Australian Institute of Geoscientists, both of whom have more than five years experience in the field of activity being reported on. Mr Glasson and Mr Smith are consultants. Mr Glasson and Mr Smith have sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which they are undertaking to qualify as Competent Persons as defined in the 2004 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Mr Glasson and Mr Smith consent to the inclusion in the report of the matters based on their information in the form and context in which it appears.

It should not be assumed that the reported Exploration Results will result, with further exploration, in the definition of a Mineral Resource.
