1. OBJECTIVE OF THIS REPORTTisand (Pty) Ltd (“RBM”) placed an order on Blue Cube Systems (Pty) Ltd ("BCS") to do an amenability study for the potential installation of Blue Cube MQi Mineral Quantifiers at the primary concentrator operations of RBM.

This report, on the results achieved from the samples sent by RBM for evaluation, is fulfilling that obligation.

2. EXECUTIVE SUMMARYFour mineral sample sets including their laboratory analyses were received from RBM.

The results of the optical scanner tests, the creation of calibration files and the interpretation of the results are covered.

Most components can be measured with potential benefits being recognised. Excellent results were achieved for THM, EHM, MAGS, MO and Ilmenite. In addition, usable results were also achieved for NM, Leucoxene and Zircon. The weakest results were obtained for MAGN, Altered ilmenite and Rutile.

Recommendations are made and a project time scale is proposed.

3. SAMPLES RECEIVED54 Samples in four sample sets were received from RBM in good order. The following three samples were too small to be analysed with the MQi Universal Spot Mineral Quantifier: MPC9, MPD18 and MPE10. The samples and their analyses as received from RBM, are listed in Annex A.

4. TESTING PROCEDUREAll the samples were scanned on a Blue Cube MQi Universal Spot Mineral Quantifier. The samples were loaded after adding 10% of water per weight to the dry samples

The scanning sequence was set at six 20-second scans per sample and the optical data was then processed with the MQi software. The first and last values from each scan were ignored and the remaining 4 were averaged for the interpretation of the results.

For each scan, the optical data was matched with the reference values as provided by RBM, and a calibration file was created for each of the four mineral groups.

The calibration file so created, was then used to predict the composition of the same set of samples.

There were adequate differences in the optical data to obtain an acceptable calibration line for the sample set. There were enough samples to minimise (but not eliminate) the matrix effects, therefore the outcome was positive.

Lastly, 49 usable sample results from all 4 groups were combined and 49 separate calibration files were created using 48 samples, in each case leaving out the data from a different sample. Each calibration file so created, was then used to predict the composition of the left out sample. Therefore the ability of the technology to predict an unseen sample was tested. Again the results were positive for some mineral components.

5. ASSESSMENT OF FITFor the sample set, the reference values and Blue Cube MQi determined values were matched in pairs. The correlation coefficient (“CC”) between the reference values and the predicted values were then calculated. The statistical standard deviation (“SD”) of the differences were also calculated. Ideally, if the SD of the differences is zero, there will be a perfect match and the CC will be 1. In reality, reference values are subject to variation and the sample being used for assessment is never identical to the reference sample. There will always be some differences between the reference values and the test values.

If the differences are small relative to the measurement range, a high confidence level can be attached to the test result but when the measurement range is smaller, the same differences will be much more significant. To create more meaning to the evaluation of tests, an assessment parameter, called a “Confidence Index” was introduced.

The Confidence Index (“CI”) is the ratio between:

the SD of the differences between the reference values and the test values of the same sample

and the range of the reference values; (Maximum value – Minimum value)

The CI is a good indication of the resolution in relation to the actual measuring range at that location. A value above 5 is useful and above 10 is strong.

In the following tables, the measurement range, the SD, the CC, the CI and the fit R-square values are all listed.

The 4 sample sets provided the following results (See Annex B for complete results):

5.1 MPAThe statistical results are given in Table 1 and graphically in Figures 1 to 11. The linkage between spectral and analytical data for sample “MPA8” however did not match the pattern of linkage between the other samples in the set and was thus not used in creating a calibration file.

6. ASSESSMENT OF PREDICTION ABILITYNext an unique calibration file was created for each sample received by using all the other samples. Thus creating an independent calibration file with which values for the excluded sample were predicted. Two samples shows analysis values far removed from the rest, and had to be disregarded for this test, namely MPC_NO11 and MPE_N08. The statistical results are given in Table 5 and graphically in Figure 45. See Annex C for the complete list of predicted values.

7. CONCLUSIONExcellent results were achieved for THM, EHM, MAGS, MO and Ilmenite. In addition, usable results were also achieved for NM, Leucoxene and Zircon. The weakest results were obtained for MAGN, Altered ilmenite and Rutile.

8. RECOMMENDATIONAgainst the background of strong results obtained, especially for THM and EHM, BCS has no hesitation to recommend that RBM consider the installation of Blue Cube MQi In-line Wet Mineral Quantifiers, to realise the financial benefits of well informed process control as soon as possible

We propose that BCS be commissioned to design, supply and install a Mineral Quantifier in each primary concentrator plant of RBM. By controlling the concentrator grade, concentrator recovery can be continuously maximised while producing a heavy mineral concentrate with an acceptable, stable grade.

9. PROGRAMThe following program should be achievable:

9.1 Amenability StudyThe amenability study will be completed with the delivery of this report.

Expected result: Decision by RBM on road forward; Number and location of MQi units.

9.2 Kick-off MeetingA kick-off meeting (can be a tele-conference) will be required to communicate the RBM decisions and to refine the final scope.

Required: Decision by RBM to go ahead.

Time Required: 1 week.

Deliverable: Defined scope of project, equipment, location, values and time schedule.

Expected result: Order for number and type of MQi units and locations to be installed. Agreement on projected time frame.

9.3 Provision and Delivery of MQi Equipment and Site PreparationBCS build and prepare the MQi equipment for shipment according to the defined time frame.

Required: Firm order from RBM on the basis of firm quotations from BCS.

Time Duration: 2 – 10 weeks depending on prior sale. This aspect will be firmed up during the kick-off meeting.

Deliverable: Equipment delivered by BCS as per scope and time schedule.

Site mounting positions and services prepared by RBM.

Expected result: Everything ready for commencement of installation.

9.4 Installation and CommissioningRequired: Site preparations complete.

Equipment delivered.

BCS personnel available.

RBM personnel available.

Time duration: 2 days per MQi.

Deliverable: MQi units functional and in communication with BCS Office and plant SCADA.

Consistency of site reference analyses verified.

Expected result: Ready for calibration.

9.5 CalibrationRequired: MQi units functional and in communication with BCS Office.

Confidential of 40


Support analytical services available at site.

Staff available for training.

Time duration: 1– 3 weeks (depending on range of process variation).

Training will take place in parallel with calibration.

Deliverable: MQi units calibrated and displaying trends on SCADA.

Expected Result: Project complete as per agreed scope.

9.6 Project Sign-offRequired: MQi units fully functional.

10. GENERALThe stated program can be firmed up as soon as RBM is prepared to place a firm order. As an alternative, it is also feasible to stage the project progressively and to install the MQi units one at a time. The impact will be a delay of payment, but at the cost of additional expenses and also, delayed gain of the benefits.

Please revert to us if you should have any further questions or suggestions.

Thank you for the opportunity to be honoured by your order for this amenability study.

Please be assured of our best efforts at all time.
