PRODUCTION COMMENTARY
Total Z/R/SR production in the second quarter was 221 thousand tonnes inclusive of Sierra Rutile, with 177 thousand tonnes from Iluka’s Australian and US operations.
The Tutunup South mine in south-west Western Australia continued to be Iluka’s only Australian mine in operation. During the quarter, 160 thousand tonnes of heavy mineral concentrate (HMC) was produced and 348 thousand tonnes processed globally. This reflected the continued draw down of HMC from the JacinthAmbrosia mine (currently idle) and the Woornack, Rownack, and Pirro mine (mining completed 2015). Iluka announced in June the planned restart of mining at Jacinth-Ambrosia from December 2017, following the substantial draw down of HMC inventory.
The company’s two mineral separation plants (MSP) at Narngulu (Western Australia) and Hamilton (Murray Basin) continued to operate as planned with the Hamilton plant scheduled to complete processing activities in October 2017, as previously announced. In addition, Iluka plans to undertake maintenance works at Narngulu in the second half for a period of two months. This will support further draw down of finished product inventories and reduce the length of future major maintenance outages. As a result, zircon and rutile production from Iluka’s Australian operations is expected to be first half weighted while quarterly variations in production levels reflect campaign timing of the plants across the quarters.
2
Higher zircon and rutile production for the first half of 2017 compared to 2016 reflects higher MSP run rates. In addition a small amount of remnant zircon concentrate stocks from the US Operations was shipped in the first half of the year and recognised as production when sold. Total zircon and rutile production for the full year is expected to remain in line with 2017 guidance.
The synthetic rutile kiln continued to operate at full capacity in the quarter.
As announced to the ASX on 3 July 2017, shipping of Jacinth-Ambrosia HMC from the Port of Thevenard was suspended as a consequence of Flinders Ports (owner of the port) closing the port due to safety concerns. Flinders Ports has since confirmed that it expects to re-open the port within three months. The port outage is not expected to have any impact on Iluka’s production guidance for 2017, nor on the company’s planned production for 2018.
SIERRA RUTILE OPERATIONS UPDATE
As previously advised, Iluka assumed control of Sierra Rutile Limited (SRL) on 7 December 2016.
Key areas of operational focus
The current areas of operational focus include the following:
-
implementation of a detailed in-fill drilling program to improve resource confidence, potentially extending current mine life and supporting mine planning and feasibility studies;
-
continue to improve operational methods and processes to ensure all operations are functioning at capacity;
-
implementation of initiatives to improve productivity at the Lanti Dredge;
-
detailed rehabilitation planning following a review of current practices;
-
development of an operational readiness plan to support the transition to in-pit mining at the end of the year at the Lanti Dry Mine;
-
updating the 5 year drilling plan with a focus on increasing reserves at current mining operations; and
-
ongoing implementation of sustainability initiatives to improve Sierra Rutile’s environmental, health and safety performance.
The work plan to reduce the operational risk levels associated with the tailings storage facilities has been completed with an external audit of the facilities also performed prior to the wet season.
June quarterly production
Rutile production for the second quarter was 43 thousand tonnes, a 21% improvement on first quarter production of 36 thousand tonnes, reflecting the following factors:
-
higher throughput and runtime associated with both the Lanti and Gangama dry mining operations;
-
opportunistic processing of minor rutile rich reject stockpiles, forecast to be completed by year end;
-
adjustments to wet concentrator plant settings resulting in improved valuable heavy mineral recovery and higher HMC grades; and
-
mineral separation plant recoveries improved with changes to plant settings following detailed metallurgical work.

As previously disclosed, capital expenditure guidance for Sierra Rutile is expected to average US$75 million per year over the four year period to 2020 (2017 SRL capital expenditure guidance: A$70 million).
MINERAL SANDS MARKETS[1]
Both the zircon and titanium feedstock markets have experienced favourable conditions in 2017 compared to the first half of 2016:
-
Z/R/SR sales volumes up 43% to 454 thousand tonnes (inclusive of Sierra Rutile);
-
excluding Sierra Rutile volumes, Z/R/SR sales volumes up 23%;
-
weighted average received zircon standard and premium price up 7% to US$871 per tonne; and
-
weighted average received rutile price up 4% to US$741 per tonne.
Zircon
Iluka’s first half zircon sales volume growth of 28% from the same period in 2016 reflects the increased sales volumes in the first quarter 2017. Demand for Iluka’s products continued to be very strong in the second quarter, influenced by underlying demand and customers’ continued demand for restocking from depleted levels. The Company’s approach has been, and continues to be, to support genuine demand of its long-standing customers rather than fuel speculative trading.
Subsequent to the price increase of US$50 per tonne that Iluka implemented effective from 15 February 2017, Iluka announced a further price increase of US$130 per tonne effective from 1 July 2017.
Iluka is of the view that, in the absence of a deterioration in global economic conditions, the demand outlook for zircon in 2017 and 2018 is for moderate growth. In Iluka’s assessment, it remains the only zircon sand supplier with significant inventories and is well positioned to meet the demand recovery for zircon.
High Grade Titanium Dioxide
Excluding the contribution of Sierra Rutile volumes, sales of rutile were in line with the first half of 2016. The inclusion of Sierra Rutile sales for the first full half has resulted in total rutile sales more than doubling period-on-period to 118 thousand tonnes.
Year-to-date weighted average rutile price rises have been consistent with Iluka’s expectation of achieving a 4% price increase in the first half of 2017 relative to 2016 levels. As noted previously, 40% of SRL’s 2017 rutile production volumes (~60kt) were contracted at fixed prices for the whole of 2017. Iluka has advised customers of a US$70 to US$100 per tonne increase effective 1 July on uncontracted rutile volumes. This represents 9% to 11% increases over the first half 2017 pricing and reflects the pricing differentials across market segments.

Sales of synthetic rutile increased 32% relative to the first half of 2016 to 138 thousand tonnes. Synthetic rutile prices increased relative to 2016 levels, consistent with contractual arrangements and market conditions. The majority of Iluka’s synthetic rutile sales volumes in 2017 are contracted.
Market conditions for pigment, the main end use sector for the high grade feedstocks of rutile and synthetic rutile, improved significantly in 2016 and this momentum has continued into 2017. Pigment inventories have been drawn down and, in many regions, remain below seasonal norms, impacted by supply disruptions and continued environmental enforcement actions in China. Iluka estimates that 2017 demand for pigment, and hence feedstock, will continue to reflect re-stocking of the supply chain, and will exceed underlying end-user demand.
In addition, pigment industry plant capacity utilisation levels have increased to levels more typical of balanced market conditions. At these utilisation levels Western chloride pigment producers typically increase the grade of feedstocks being fed into their plants as a means of increasing plant outputs. If the industry follows past practices, this will be positive for demand for high grade ores.
The increase in ilmenite sales largely reflects Sierra Rutile volumes, with the majority of Iluka’s existing ilmenite consumed internally in the production of synthetic rutile.
Weighted Average Received Prices
The following table provides weighted average received prices for Iluka’s main products over the last three half year periods. The Iluka Review, available at www.iluka.com contains further historical mineral sands price information.

Notes:
-
1: Zircon prices reflect the weighted average price for zircon premium and zircon standard, also with a weighted average price for all zircon materials, including zircon-in-concentrate. The prices for each product vary considerably, as does the mix of such products sold period to period. In the first half of 2017 the split of premium, standard and concentrate by zircon sand-equivalent was approximately: 59%:30%:11% (2016 full year: 47%;33%;20%).
-
2: Included in rutile sales is a lower titanium dioxide product, HYTI that typically has a titanium dioxide content of 70 to 91%. This product sells at a lower price than rutile, which typically has a titanium dioxide content of 95%. In 2017, ~7% of total sales in this category were of the lower grade HYTI material (2016 full year: 9%).
-
3: Iluka’s synthetic rutile sales are, in large part, underpinned by commercial offtake arrangements. The terms of these arrangements, including the pricing arrangements are commercial in confidence and as such not disclosed by Iluka. Synthetic rutile, due to its lower titanium dioxide content than rutile, is priced lower than natural rutile.

PLANNED NEW PRODUCTION
Cataby, Western Australia
The Cataby mineral sands deposit, located north of Perth, is a large chloride ilmenite deposit from which Iluka plans to produce ilmenite as a feed source for synthetic rutile production, as well as material volumes of zircon and rutile. Cataby is expected to have an economic life of approximately 8.5 years.
The definitive feasibility study has been completed and various pre-execute activities, including environmental approvals and amenity agreements, continue on schedule, along with work to further refine and optimise the project configuration. The decision to proceed with the project is dependent on securing appropriate offtake arrangements. Discussions with major chloride pigment customers and others are progressing.
As stated in the Managing Director’s address at the Annual General Meeting, the 2017 capital expenditure guidance of $260 million includes approximately $150 million related to Cataby. While a proportion of the Cataby capital – approximately $20 million – will be spent on detailed engineering work and land access in 2017, the expenditure of the remaining amount will depend on the timing of a development commitment.
Balranald, Murray Basin, New South Wales
Balranald and Nepean are two rutile-rich mineral sands deposits in the northern Murray Basin, New South Wales.
Work on the unconventional mining development at Balranald has continued in 2017. Work on testing an improved mining head to assess suitability is underway. Should the testing of the mining unit prove successful, a decision will then be made on whether to proceed with a final field trial in 2018.
Puttalam (PQ), Sri Lanka
The Puttalam Quarry (PQ) mineral sands deposit is a large sulphate ilmenite deposit, located approximately 30 kilometres north of the town of Puttalam in the North Western Province of Sri Lanka and approximately 170 kilometres from the capital, Colombo.
PQ project work is focussed on legal and investment terms for the development and includes securing surface access rights, ministerial and other governmental approvals. Discussions with the Sri Lankan Government have commenced on establishing a pathway towards Iluka securing a binding Development Agreement. Iluka has submitted a revised and comprehensive project proposal and joint working group meetings have been established with the appropriate government ministries to progress the negotiation of the Development Agreement.
A pre-feasibility study is being undertaken on the PQ deposit with in-country consultants being engaged to progress various engineering, environmental, hydrogeological and infrastructure work packages.
Refer Iluka’s website (www.iluka.com) – Section: Company Overview, Projects, for more detail on these projects.

EXPLORATION
Expenditure on exploration and evaluation charged to the profit and loss account in the first half was $5 million (of which $2 million was spent in the second quarter), compared with $10 million in the same period of 2016.
Kazakhstan
The regional air-core drill program began on GIN1[1] in June 2017. The project is targeting marine shore geological formations containing zircon-rich heavy mineral assemblages. It will take two to three months to complete the drilling across all 3 GINs with analysis to follow.

Finished product provides an indication of the finished production (zircon, rutile, ilmenite) attributable to the VHM in HMC production streams from the various mining operations. Finished product levels are subject to recovery factors which can vary. The difference between the VHM produced and finished product reflects the recovery level by operation, as well as processing of finished material/concentrate in inventory. Ultimate finished product production (rutile, ilmenite, and zircon) is subject to recovery loss at the processing stage – this may be in the order of 10 per cent.
Ilmenite is produced for sale or as a feedstock for synthetic rutile production.
Typically, 1 tonne of upgradeable ilmenite will produce between 0.56 and 0.60 tonnes of synthetic rutile. Iluka also purchases external ilmenite for its synthetic rutile production process.
