Code, the number of check samples compared to the total database is very small (approximately 0.6%) and

was biased towards samples collected in the 1970s and 1980s.

Metorex has accepted the historical data as suitable for mineral resources estimation work on the basis of this

limited check sampling, and the results of the 2005/6 and 2009 drilling, even though the majority of the

database is not supported by adequate QA/QC. However, Ruashi mine is a mature producing entity and the

copper production over the years has shown consistency with the predictions of the drill hole database. This

consistency in copper production largely mitigates the insufficient QA/QC so that the quality of the resources as

classified can be accepted.

The areas where mining is being done at present are supported by drilling on a 25m x 25m drill spacing with

good QA/QC. These resources/reserves should be sufficient for the next 4-5 years. The IGS comments remain

a concern and Ruashi would be advised to conduct regular reconciliations between planned and actual metal


It is essential that the assay quality control programme instituted at the Ruashi Mine laboratory be strictly

adhered to as a means of improving the confidence in all new assay results received. The Ruashi Mine

geological and analytical laboratory staff have received training in this respect, and a procedure is in place to

ensure all drill hole samples to be used for estimation purposes, are accompanied by the appropriate level of

blanks, CRM and repeat samples to ensure compliance.

3.6.5 Bulk density and bulk tonnage data

Bulk density measurements were taken on 1 168 samples from the 2009 drilling programme across lithological

domains and across a range of depths, and were measured on air dried samples. Because some black ore

mineral zone (“BOMZ”) core samples would actually float on water, a dry medium (sugar) was used to

calculate the volume with weight measured using a digital scale. During 2010, a standard SNOWRIX model

NHV-3 digital density scale was used for all the “non-floating” rock density measurements.

Plots of grade versus SG and depth versus SG were created for the different domains but no discernible trend

was evident. An average density was used for each domain and the mixed zone was assigned a value midway

between the oxide and sulphide values. The dolomitic units generally have a higher density than shale, and the

BOMZ shows low to very low density. The sulphide densities average 2.5 t/m3. Table 3.4 shows 2009 and 2010

The waste rock density was based on the data from 2006 drilling. A relationship established between density

and depth was applied in the definition of waste densities in the model, subject to a maximum value of 2.7 t/m3.

3.6.6 Geological Modelling and Zones of Mineralisation
[SR4.1A(ii)(iv), SR4.1A/B, SR4.2A, SR4.2B]

The geological model for the Ruashi Mine was constructed on the basis of identification of major lithological

units and the merger of thinner and discontinuous units to ensure continuity across the drill holes consistent with

the major structural features including geological discontinuities.

The main geological features identified are a recumbent fold with flat lying and vertical faults causing stretching

and fragmentation into three parts resulting in the Ruashi I, II and III ore bodies. Depth of oxidation and

weathering intensity vary depending on the rock types. Depth of weathering varies from 50 m to 300 m below


The lithological units modelled are listed in Table 3.5.

The availability (or lack) of skilled personnel required to implement and operate sophisticated procedures is of


3.19.6 Mineral Processing
Metorex has provided for the installation of 15 MW of diesel-generated power to supplement the power supplied

by SNEL. The Caterpillar diesel generators will be commissioned in August 2013. The Agrekko generators

with a capacity of 13 MW that were on lease will be purchased during H2-F2013 and this will further decrease

the dependence on SNEL. Nevertheless, the forecast production levels may be optimistic as these production

levels have not been previously achieved.

Co recovery in H1-F2013 was only 67.7%. If the poor Co recovery in March 2013 is excluded, the Ruashi Mine

exceeded the target 71% Co recovery in H1-F2013.

Power dips affect the availability of SO2 and the supply of steam to the dryers. Metorex reports that the SO2 and

acid plant is connected to the back-up power supply therefore the risk in non-production due to power dips is


The forecast production levels are based on successful debottlenecking of the plant, sustaining a 92% running

time, and the successful operation of the SO2 plant.

Sale of acid is dependent on the continuation of the off-take agreements.

The inventory of diesel will need to be carefully managed, given the delays through the border and the

increased demand for power generation. Metorex has entered into a 12-month diesel supply agreement.

Metorex has received written confirmation that the suppliers will be able to meet the increased diesel demand

due to running 20 diesel-powered generators.

The commissioning of the diesel-generator sets in F2013 will effectively make Ruashi self-sufficient in terms of

power supply, thereby minimising the effects of the power interruptions that plagued production in F2012. As

SNEL power becomes more reliable with the interventions by mining companies in the DRC, Ruashi’s reliance

on diesel-generated power will reduce with accompanying reduction in operating costs.

3.19.7 Engineering and Surface Infrastructure
The main issue faced by Ruashi mine has been the poor availability of electricity in the region, coupled with an

unstable supply when it is available. This is compounded further by the premature failures to electrical

equipment such as motors, VSD drives, control and instrumentation equipment. The internet communications

and IT-based equipment also suffers with damage due to the power supply issues. The mine has increased the

installed diesel generation capacity on site to around 23 MW, which has drastically reduced the mine’s reliance

on SNEL and ZESCO for power. The introduction of the Agrekko diesel generators has drastically improved

electrical power availability to the site.

The planned maintenance system needs to be refined to improve the engineering department’s ability to report

on equipment costs and work history. Presently unplanned job cards are not religiously completed, but the

CMMS upgrade plans are in place and work is underway by Metorex to include unplanned job cards in the

reporting structure going forward.

3.19.8 Logistics
Possibly the highest logistics risk that Ruashi Mine faces is the extended periods that road vehicles have to

endure at the DRC-Zambia border crossing point, especially the fuel (diesel) vehicles, necessary to power the

mining fleet and the diesel powered generators. Metorex had initiated a tender process to secure sufficient

diesel for the generators. Metorex has received written confirmation that the suppliers will be able to meet the

increased diesel demand due to running 20 diesel-powered generators.

Diesel supply and inventory control have been demonstrated during Q2 2013.

3.19.9 Human Resources
There is a risk that the termination benefit at closure which has been set equal to a 6 month obligation may be

understated. Metorex reports that the termination benefits are reviewed on an annual basis to ensure that

adequate provision and funding are in place. Any annual adjustment will not be material to the overall group.

3.19.10 Occupational Health and Safety
The safety statistics reflect the standards of safety, maintenance, repairs and operations seen on site at the

Ruashi Mine operations. Given the observations made by SRK during its visit to the EW section, it does tend to

suggest that there is a worker behavioural issue that is impacting on safety performance. Metorex referred to

this as the “cultural tolerance to risk”.

The risk is that if the work based auditing and planned task observation processes carried out by management

and supervisors are not maintained, safety standards may slip. Metorex has advised SRK that management

continues to concentrate its efforts on employees’ behavioural attitude towards safety and health in the work


3.19.11 Environmental
The Equator Principles audit undertaken in 2011 identified the management of ground and surface water

resources as the key environmental challenge facing the Ruashi Mine. The audit was repeated in 2012 but this

conclusion remains applicable, although it is noted that significant progress has been made in addressing

issues from the 2011 audit.

The risks associated with the closure cost estimate include:

 The possibility of ongoing long term water treatment post closure;

 Unexpected social costs due to community expectations being enforced.

 Closure related environmental, social and economic risk identification; and

 Provision for aftercare, maintenance and monitoring. (There is provision for this in the closure cost estimate
by Steadman but it is possible, especially in the light of the fact that a contaminated ground water plume

potentially represents the single biggest environmental risk, that the provision is inadequate.)

The Ruashi Mine is faced with several social challenges / issues related inter alia to poverty in the area, poor
basic infrastructure in communities, high community expectations and government scrutiny. The mine is

involved in several Corporate Social Responsibility projects in the areas of education, health, infrastructure,

potable water and power. These projects, which are co-ordinated by a committee on which the mine, the

mayoral office, the water and electricity utilities and local chiefs are represented, are continuing.

Metorex has been alerted to the potential shortcomings of its current closure planning and an action plan has

been developed to mitigate their effects.

Metorex has a group-wide provision for post-closure water treatment of around USD5 million. In SRK’s

experience, this figure is likely to be considerably more. SRK has in agreement with Metorex increased this

provision for post closure water treatment to USD25 million for the group for evaluation purposes, of which

USD10 million is allocated to Ruashi. The additional provision does not eliminate this risk, but it reduces the

potential financial impact on the company significantly.

Interpretation of on-going water monitoring results will assist in the investigative work required to assess the

likelihood and extent of the post closure water treatment being required.
