One-Belt One-Road initiative: episode one

China’s One-Belt One-Road initiative (OBOR1) is the core element in the nation’s Eurasian foreign policy. This edition of Prospects will discuss OBOR from a high level perspective. A subsequent episode will build on this foundation to define what this ambitious initiative might mean for our portfolio of commodities in the longer run.

China’s four-decade long boom, coupled to its immense geographic and demographic scale, has returned it to its traditional position at the centre of the East Asian economy. Along the way it has built unprecedented reserves of foreign assets; become the largest trading partner of more than half the globe and risen to a leading position in multiple segments of the global manufacturing supply chain. China is the largest single market for everything from cars to mobile phones and e-commerce to international tourism. It is also the largest consumer of a wide range of commodities across the energy, minerals and agricultural fields. Despite this impressive catalogue, there is more to be done, as all of this effort has, at this stage, only raised the living standards of the average Chinese citizen to the middle income level.

To become a prosperous twenty-first century society, the Chinese economy must continue to ascend the value-added chain by building up its innovation capabilities. It must also improve the long run allocation of capital whilst accommodating the rise of consumerism – all while managing the legacies of the old growth model. OBOR helps on all counts.

The origins of the trillion dollar, continent-straddling version of OBOR we see today can be traced back to earlier, less ambitious policies. Some were aimed at developing China’s regional sphere of influence. Others sought to spread the benefits of what was then predominantly coastal economic development into China’s less developed interior provinces.

In the late 1990s, a “Go Outward” policy was instituted, encouraging Chinese firms to invest abroad. In the early 2000s, the Shanghai Cooperation Organisation (SCO) was founded, which systematised high level Chinese engagement with a group of central Asian countries positioned along what is now the “Silk Road Economic Belt”. There was also a “Go West” strategy, aimed at developing China’s poor interior provinces, many of which shared land borders with central Asian nations. In 2009, President Hu tightened relations with central Asia with a range of state visits, high profile investments and economic partnerships. And then, in 2013, President Xi Jinping introduced the names “Silk Road Economic Belt” and “Maritime Silk Road” on official visits to central and south-east Asian nations respectively.

Under President Xi’s sponsorship, serious money began to be ear-marked for projects under the OBOR banner, highlighted by the US$40 billion “Silk Road Fund”. A “Leading Group”2  reporting directly to the State Council was established. China is also the cornerstone investor in a new multilateral lending institution, the Asian Infrastructure Investment Bank (AIIB), which has already funded a number of major projects in OBOR countries.3

From a purely economic standpoint, OBOR provides a signal and a framework for Chinese firms to export their growing expertise in infrastructure, manufacturing and construction. The financing of OBOR projects offers an avenue for diversifying China’s foreign assets away from low yielding sovereign bonds to higher yielding real assets. In the second wave, the increasing prosperity of recipient countries, where shortages of basic infrastructure4 are a major impediment to improving the livelihoods of their citizens, will provide expanding markets for Chinese goods. China’s heavy industries, many of which are experiencing excess capacity after a decade of very strong investment sentiment, will enjoy having an additional outlet for their wares in both waves of this journey. This could help soften the blow of the inevitable restructuring that domestic economic rebalancing will entail.

One-Belt One-Road

From an energy and trade security standpoint, OBOR protects and develops critical pipeline infrastructure and transport corridors on land; and it overlooks vital Eurasian shipping lanes on the maritime belt. Vast sums have been invested by Chinese firms to gain a foothold in multiple ports along the Indo-Pacific coast of Eurasia, with clusters of investment centred on major locations including the Straits of Malacca, Sunda, Hormuz, Gibraltar and Bab al-Mandab, as well as Suez. The links between the Belt and the Road (such as the “China-Pakistan Economic Corridor”, which hits the Indian Ocean at the Port of Gwadar) also provide China with alternative routes to reach the European, African, South Asian and Middle Eastern markets. There is also a possibility that northern Australia, a strategically located region with a complementary resource endowment to China’s, could become an important link in OBOR at some point.

Making condition-based monitoring a reality with the IoT

Condition-based monitoring is an essential component of predictive maintenance, recording changes in equipment that could lead to a fault. This is necessary across a wide range of industries, including manufacturing, mining, infrastructure, utilities and water.

With the advent of the Internet of Things (IoT), the measurable condition(s) of a machine can now be monitored continuously and in real time through a combination of connected devices and sensors, data networks, cloud storage and Big Data processing. All of these components work together to analyse data, which is easily communicated to the operator.

Without harnessing IoT solutions, data transportation can become a significant issue. According to Jas Singh, Systems and Solutions Manager at ifm efector, approximately 95 per cent of the data produced by sensors and other devices is unutilised or lost. For this reason, ifm has developed its Line Recorder series, which acts as a gateway to the IoT through a range of solutions for machine analytics, predictive maintenance and condition-based monitoring.

For condition-based monitoring in particular, ifm has developed SmartObserver, a software that provides an interface for users to undertake real-time maintenance (RTM). Within this RTM system, the customer can view both live and historical data, and perform data analytics. Potential applications for this software are endless; from conducting vibration monitoring on fans in a tunnel or centrifuge pumps on wind turbines, to monitoring truck driver fatigue, fuel levels and speeds.

One unique feature of SmartObserver is that it allows the user to remotely interact with their machines. This is made possible through an alarm management feature, where the user can receive an SMS, with the ability to acknowledge a particular alarm through text. What’s more, SmartObserver offers users the ability to interface to multiple devices, whether they be legacy devices or the latest device on the market.

Potential benefits for industry include:

  • Timely identification of possible damage or production stoppages, resulting in more efficient production and quality assurance
  • Energy savings and cost reduction by monitoring and customising machines’ energy usage
  • Access to more data than ever before, along with the ability to easily manipulate the data to discover important trends

These benefits are supported by a range of features such as:

  • Data acquisition and diagnosis
  • Visualisation and analysis
  • Alerting
  • Analysis and trending
  • Online access
  • Export data for testing and certification
  • Planning functions
  • Continuous condition monitoring
  • Intermittent condition monitoring
  • ERP connectivity

BGC wins $720 million contract for Arrium’s SA iron ore projects

BGC Contracting has secured a five-year contract worth more than $720 million for Arrium’s Iron Knob and South Middleback Ranges iron ore projects near Whyalla in South Australia.

Arrium administrators KordaMentha confirmed that BGC’s current mining contract, which was to be completed this year, will instead be replaced by this new contract until 2022.

BGC will provide a range of mining services under the new contract including drilling, blasting, hauling, loading, dumping and train load-out.

BGC CEO Greg Heylen said the contract reflected the strong partnership the company has had with Arrium over the past four years.

He added that BGC’s strengths were in it being privately owned and vertically integrated, which allowed it to adapt to changes in the market.

“This has been a challenging time for the mining sector as it dealt with the decline in the commodities markets in the short term,” Heylen said.

“BGC Contracting’s breadth and vertical integration of services has enabled us to improve efficiencies on the project, which has resulted in lower cash costs for Arrium and the administrators.

“During this time we have continued to meet Arrium’s safety and production targets and we look forward to continuing our work with Arrium’s team in the future.”

Heylen also said he looked forward to providing more certain employment for workers and subcontractors in the Whyalla region.

Arrium Mining executive general manager Matt Reed said the collaboration provided benefits for both companies, with BGC playing a major role in helping Arrium lower its mining costs.

“We look forward to developing this partnership with BGC over the coming years and continuing to reduce our costs as we create a world-class business,” Reed said.

PAYLOAD DATA AIDS IN THE RAPID MOVEMENT OF AGGREGATE

Georgiou Group’s fleet was entrusted with moving 600,000m3 of sand, rock and limestone 1.5km between the cut and fill zones of the Alkimos project.

PAYLOAD DATA AIDS IN THE RAPID MOVEMENT OF AGGREGATE

A major civil construction company charged with moving 600,000m3 of sand, rock and limestone on a land development project completed its assignment in advance and at a significant cost saving to its client – thanks to a combination of surveying, measurement and load and haul programs.

Georgiou Group is a national building construction, engineering and property development company that delivers major projects across Western Australia, Queensland, Victoria and New South Wales.

It is a low cost, high performance company that wanted to improve productivity and cost control on a land development project. The six-month project in Alkimos, about 50km north of Perth, Western Australia, involved moving 600,000m3 of sand, rock and limestone 1.5km between the cut and fill zones. The site measured 2km long by about 600m wide. Georgiou turned to SITECH Western Australia and Trimble Loadrite for help in understanding payloads, the movement of material and the productivity of operators and mass haul routes.

Augmented site solution

In the past, Georgiou had manually collected payload data to map to cost centres. The company had no access to real time data on productivity and material movement, leading to potentially inaccurate and sometimes delayed information.

On this project the Georgiou team adopted a range of Trimble solutions, including the 3D GCS900 Grade Control System, 2D Project Monitoring on haul assets and Loadrite X2350 excavator scales.

Data from this hardware was used by InsightHQ and VisionLink software to improve productivity, increase data transparency and accuracy, and therefore reduce costs. Georgiou used Business Center – Heavy Construction Edition (HCE) software for mass haul analysis and design creation. Utilisation of the SCS900 site controller software and unmanned aerial vehicles augmented the site solution.

Georgiou project manager Jim Ryan and Georgiou machine control lead Ian Hitsert led the project and began by equipping two 125-tonne excavators and one 85-tonne excavator with the Loadrite X2350 excavator scales and 2D VisionLink monitoring devices. The Loadrite X2350 excavator scales reported live data to InsightHQ for analysis and goal-setting. Monitoring devices were also fitted to 16 dump trucks.

The primary goals focused on productivity, tracking material moved, reducing the carbon footprint and keeping staff a safe distance from machines on the jobsite. Trimble’s VisionLink – a fleet, asset and site productivity management software – was then used to capture data from dump trucks, to be analysed and displayed through dashboards available on iPad. The Loadrite system gave excavator operators precise weight information to optimally load dump trucks. Trimble GCS900 GPS systems were used to track project progress and monitor material movement and the locations where material was cut and filled.

Georgiou also used Business Center – HCE’s Corridor Mass Haul module to create a digital terrain model of the Alkimos project site, define haul zones and perform a comprehensive mass haul analysis of the project.

Accurate, real time data

“The technology solution provided by Trimble and the working partnership developed with SITECH WA has allowed Georgiou to discover the benefits this technology can deliver to the business for earthworks projects of this size and nature,” Hitsert said. “The positive outcomes from this project have enabled Georgiou to utilise this technology to manage productivity on future projects. With a better understanding of the Trimble hardware and software, we are now challenging Trimble to provide additional functionality, to further improve productivity.”

Ryan estimated the cost savings to the project were in the order of 20 per cent, explaining one of the biggest advantages of the system was being able to determine and track the cost of moving a cubic metre of dirt on a daily basis. Project management could see how quickly trucks were being loaded and show operators their individual productivity data compared with other operators.

“We had two guys running two PC-1250 excavators and noticed production on one machine was slower than the other,” Ryan said. “We swapped these guys around to see if it was the excavator, and it wasn’t. With accurate data about payloads, we could see this kind of information immediately and easily start the conversation, as we had actual data to point to. We found ways to improve their performance, with more accountability through daily, even hourly, production check-ins.”

Operators running excavators and dump trucks were able to work as normal, loading material from the first cut zone and dropping it at the fill zone. The Trimble SNM940 Connected Site Gateway relayed production data to VisionLink and InsightHQ to gather payload information.

Ryan said data from the Loadrite scales centralised performance and productivity information across the range of machine sizes, brands and models.

Ryan and the equipment operators had real time information about load counts, idle times, time stamps when trucks are loaded, and travel time for material movement. From the office and using iPads in the field, supervisors could access information immediately and work with operators to improve productivity.

Ryan said on a daily basis supervisors could see project status, comparing a six-month project timeline to productivity to date. This replaced the old method of manually capturing data that could sometimes be inaccurate and days behind.

“Today, with Trimble Business Center – HCE and VisionLink, we have the real time cost and production status at the touch of a button,” said Ryan.

“We don’t have to go out and do any manual spreadsheets, collecting load counts for all machines and mapping them to cost centres. The technology doesn’t build the job for you, but we’ve taken full advantage of using the data to work more efficiently, and it has had a positive impact on the bottom line.”

To track the progress of material moved at the end of each month, the Georgiou team also ran Trimble’s UAV system to capture point cloud data and build a terrain model of the Alkimos site.

“Because earth was being hauled continuously, there was lag time from when we captured data from the UAV system to when we processed it and created reports,” Hitsert said. “In Business Center – HCE we would re-compute our corridor mass haul volumes to design and track progress in terms of overall volume. Essentially, we would re-compute mass haul, load it into VisionLink and back date it to the day of the UAV flight, which was a big plus for us because then we had a full picture in VisionLink of how much material was moved from that date forward.”

Cost, time savings

Within two weeks of using both Loadrite excavator scales and InsightHQ reports, Ryan and the team realised that although each truck was full by volume, they were under-loaded by weight due to lower density material, and could take a further eight tonnes each.

“We saw quickly from our haul routes and material production reports that loading each truck with 32 tonnes of material was inefficient,” Hitsert said. “To improve material moved per day, Georgiou’s internal plant department fitted steel plates around the tops of all dump trucks so we could carry 40 tonnes of rock, sand and limestone instead of 32. We never would have known this without the Trimble technology.

“As a result, and with the same haul fleet, we were actually able to finish moving 600,000m3 of material in four months, instead of six, providing significant cost and time savings to our client.”

New Report Captures Equipment Manufacturers’ Contributions to Economy

The equipment manufacturing industry supported almost 1.3 million jobs in the United States in 2016, according to a new report released Thursday by AEM.

The report, which was produced by the leading economic research firm IHS Markit, found that equipment manufacturers added $159 billion to the Gross Domestic Product (GDP) of the United States last year.

The report came as major segments of the equipment manufacturing industry met at CONEXPO-CON/AGG in Las Vegas, and as national elected leaders place a renewed emphasis on manufacturing jobs and infrastructure investment.

The research project offers the best snapshot of the equipment manufacturing industry’s reach in several years.

The report found that equipment manufacturers in the United States supported over $416 billion in sales activity in 2016, generated about $87 billion in labor income (amounting to about $78,000 in wages per equipment manufacturing industry job), and contributed over $25 billion in local, state and federal taxes.

Texas leads the country in equipment manufacturing employment and output, the report found, followed by Illinois, Wisconsin, Ohio and Iowa.

The research also examined the equipment manufacturing industry’s impact in Canada. Equipment manufacturers in Canada supported some 149,000 jobs last year, and generated some $15 billion (USD) for the Canadian economy in 2015.

“AEM is proud to represent the men and women of the equipment manufacturing industry across our country. This new report helps to put into context the many great contributions of our industry,” said AEM President Dennis Slater. “Our industry is a core part of America’s manufacturing economy, and we are eager to continue to grow, and, hopefully with a significant investment in our infrastructure, help put millions of Americans to work.”

IHS Markit additionally examined the equipment manufacturing industry’s impact over the construction, agriculture and energy (including oil and gas and mineral exploration) equipment segments. IHS Markit found that construction equipment manufacturers make up about 38 percent of the industry and directly support 163,000 jobs; farm equipment manufacturers represent 27 percent of the industry and directly employ about 114,000 people; and energy equipment manufacturers account for about 35 percent of the industry and directly support 148,000 jobs.

The research examines the direct impact of equipment manufacturers on the economy, as well as indirect effects at suppliers, service providers or other ancillary businesses related to the industry. The report also accounts for the induced effects of the industry (i.e., the additional effects on employment and income in communities).

The report adds additional detail about some of the key variables that support each industry segment, and forecasts growth for the industry into 2018 and beyond.

WA still Australia’s top spot for mining investment

Western Australia remains the most attractive jurisdiction in Australia for mining investment, according to Canadian think-tank, the Fraser Institute.

However, the behemoth mining state dropped from the top spot globally in the organisation’s 2016 annual survey of mining executives to third in 2017 behind Canadian provinces, Saskatchewan and Manitoba.

The survey ranks 104 jurisdictions around the world based on geologic attractiveness and the extent government policies encourage or deter exploration and investment.

Queensland (10th) is the only other Australian state to feature in the top 10 jurisdictions, improving from 16th overall in 2016, even though its overall rating score declined slightly.

Behind the top three were Nevada (United States), Finland, Quebec (Canada), Arizona (US), Sweden, Republic of Ireland, and Queensland.

Despite having just two states in the top 10, Australia and Oceania did manage to surpass Canada and the US as the most attractive region in the world for investment when both policy and mineral potential are considered, Fraser Institute added.

“WA was rated to be the most attractive jurisdiction in the region and the third most attractive jurisdiction in the world this year based on its investment attractiveness score,” Fraser Institute reported.

“Two Australian jurisdictions— New South Wales and Queensland — experienced declines in their policy perception index (PPI) scores this year.”

NSW’s PPI score was notably lower, falling from 51st in 2016 to 66th this year, as more respondents rated socioeconomic agreements/ community development conditions, labour regulations, and the legal system as discouraging to investment.

It is the fifth consecutive year that NSW suffered a decline in its PPI score.

While Queensland’s PPI score decreased, the lift in the state’s investment attractiveness score was driven by a substantial improvement in miners’ views of Queensland’s geology.

“In fact, this year Queensland is rated as having the fourth most attractive geology in the world,” according to the Fraser Institute.

The Australia and Oceania investment attractiveness index rankings order in 2017 is: WA, Queensland, South Australia (13th overall), Northern Territory (20th), Fiji (41st), Tasmania (56th), Victoria (57th), Papua New Guinea (59th), NSW (62nd), Philippines (66th), New Zealand (67th), Indonesia (78th) and Malaysia (93rd).

Sandvik, IBM partner to bring advanced analytics for mining sector

Sandvik Mining and Rock Technology has partnered with IBM to develop data driven productivity and predictive maintenance services for the mining and rock excavation industry.

Under the agreement, the two companies will develop advanced analytics solutions to improve maintenance, safety, productivity and operational services of mining and rock excavation equipment.

The rising number of onboard instrumentation and data gathering capabilities in heavy equipment have provided mining operators more opportunities for increased productivity; with the use of digital technologies estimated to create around $100bn in value to resources companies by 2035.

The collaboration will involve the use of remote monitoring, advanced analytics, and cognitive technologies, allowing mining companies to combine equipment data from a range of resources and automatically analyse the patterns to increase performance.

The first state of work will be done on loaders and trucks; connecting up to 15 units and integrating live data from multiple on and off boarding systems to run the analytic algorithms.

The combined information will allow mining companies to make better production plans and maintenance schedules for their equipment.

It is also set to generate greater yields and lower costs per tonne of ore.

Sandvik has identified between 20 and 50 per cent decreases in costs per tonne with their digital technologies, and these new analytic capabilities are set to reduce costs even more.

President of Sandvik Mining and Rock Technology, Lars Engström, said the company’s OptiMine and AutoMine solutions for data collection already provide a suitable platform for IBM analytics solutions.

“This collaboration fits well with our service portfolio, which is based on traditional life-cycle, enhanced technical, and business services, all of which are aligned to improve safety, secure competences for mine operations and increase our customers’ productivity,” he said.

Anders Fredholm, VP Industrial Products Industry, IBM Europe also welcomed the collaboration and said the company looks forward to providing smarter digital services to natural resources companies worldwide.

Rio Tinto slashes more jobs at Queensland aluminium smelter

Rio Tinto is cutting more jobs and production at the Boyne aluminium smelter at Gladstone in Queensland.

According to Reuters, Rio, with its Boyne partners, will reduce output at the operation by 14 per cent due to a sustained increase in power prices. The move will reportedly result in job losses in excess of 100.

The diversified miner announced in January that production at the smelter would be reduced by eight per cent. The previous decision was expected to cost about 50 jobs.

However, with high power prices continuing to affect the operation, the job cuts are expected to more than double what was previously foreshadowed as the smelter lowers its annual aluminium production by about 80,000 tonnes.

Boyne Smelters released a statement in January explaining that the operation was unable to maintain full production due to sustained high power pricing, almost three times higher than the 2016 average.

The smelter sources about 85 per cent of its power from the Gladstone power station.

Boyne general manager Joe Rea said: “This is the second time in three years we’ve had to curtail production on a large scale because of uncompetitive electricity prices. BSL is paying more than 500 times more than what it costs to generate electricity.

“The decision to curtail production is a very difficult one. It takes months, not weeks, to bring the smelter back to a stable full capacity, and that can only happen if and when power prices become competitive.”

Boyne employs around 1000 people and indirectly supports about 6700 jobs nationally, with 3000 of these jobs in the Gladstone region.

Rio owns about 60 per cent of the smelter operations.

Improving operational performance with mill lining design

As operators seek to optimise income from mining, operational excellence and the ability to find new productivity gains are key focus areas.

Tactics to achieve this include a re-evaluation of a mine’s maintenance and procurement approach. The two are entwined because a tendency to exhaust equipment and/or rely on tried, tested and sometimes under-performing components can lead to more frequent downtime.

Whether it’s a planned service or an emergency shutdown, any interruption to operations can have costly consequences.

An example where this approach is being put into practice is in milling technology for mineral processing, where new equipment and processes are being introduced to optimise production efficiency. This includes reducing the number of production lines in action at any one time, so increasing mill sizes to enable the same, if not greater, throughput levels.

One of the key advantages to this approach is that scheduled and unscheduled downtime is reduced. However, the activity levels of each mill must be closely managed to ensure that productivity remains high.

Similarly, components used within the mill must guarantee optimum performance and reliability, so that unexpected maintenance or replacement is minimised.

According to Trelleborg engineered products technical manager Zane Thomas, mill liner design and material selection is important to ensure the optimum flow of minerals and longer lasting performance of the lining.

“Liners play an important role in protecting the interior mill shell from impact and wear, while transferring energy to optimise grinding efficiency. These conflicting requirements mean that the lining must be carefully designed to ensure optimum, long lasting performance and reduced load stress on the mill,” Thomas said.

“A key consideration is the material used to make the lining and lifter bars. For some materials, such as composite steel linings, the wear life can be unpredictable due to the quality of the steel, bonding techniques and the cracking of inserts.

“This can become a safety hazard requiring frequent maintenance and replacement, not to mention the additional load in the mill. The result is a loss in efficiency and throughput, increase in power draw and downtime losses, all affecting the dollar per tonne recovery.”

 The benefits of rubber compound versus composite steel linings

Used in most secondary, tertiary and a number of primary milling applications, rubber mill linings are almost half the weight of composite steel liners and come with huge advantages, such as the elimination of cracking or falling of inserts during mineral impact, as well as reduced noise levels during milling.

Rubber mill linings are easily monitored and wear life is predictable. Some components can also be designed with wear indicators incorporated, making it easier to identify when the lining needs to be replaced and therefore, when to schedule appropriate maintenance.

As the pressure to reduce unplanned downtime builds, in order to improve efficiency and mill productivity, the ability to measure liner wear becomes invaluable.

An all-rubber lining has been developed for composite lifter bar solutions. For example, Trelleborg recently developed and supplied a cost-effective, long-lasting rubber lifter bar solution for a ball mill in Australia.

The success with the 1605AM rubber compound and design has given Trelleborg the opportunity to offer its clients an alternative to composite steel lifter bars.

“Composite lifters can not only add to the load in the mill, but are also difficult to handle in confined spaces and take much longer to install, adding to downtime and installation costs,” Thomas said.

“The lifter bars made with new 1605AM rubber compound come with added benefits such as easy handling, quick installation time, reduced power draw and noise pollution. The reduction in overall weight decreases the impact on rotating components.”

Downtime is a significant issue faced by the mining industry, and the mining and material processing industry is always looking for ways to enhance availability of the mills that grind and blend materials, Thomas added.

“Trelleborg’s rubber lifter bars offer increased operational efficiencies, significantly reduced downtime, simple wear monitoring and life predictability. In addition, when compared with steel, a rubber solution also provides superior resistance to the severe impact, high temperature and abrasion caused by the comminution of the ore within the mine’s grinding mill, enhancing the life of the mill,” he said.

Trelleborg offers a wide range of rubber lifter bars and plates for ball mills, rod mills and drum scrubbers. The standard rubber lifter sizes from Trelleborg range from 50mm to 250mm wide and 50mm to 350mm in height.

They come with aluminium and steel tracks, with different face angles to suit the milling or scrubbing application. A wide range of shell plates, grate plates, head plates and filler segments, including the backing rubber to protect the mother plate of the mill are also available.

 Conclusion

Accessible measures and practices are available to help operators to get the most out of every mill.

Though considered just one of many components vital to mining operations, the lining of a grinding mill plays a key role in optimum comminution and mineral dressing.

Lines are subjected to severe impact and abrasion from the mineral being ground and the media introduced into the mill to help break down the product.

As such, a high quality and high wearing lining is an important part of keeping a mill online and operations running to plan.

OceanaGold plans to battle Philippines move to suspend mine

Australia’s OceanaGold intends to take legal action if a proposed move in the Philippines to suspend or close a series of mines in the country, including its Didipio operation, for environmental reasons goes ahead.

Philippines’ environment and natural resources secretary Regina Lopez yesterday ordered the suspension of five mines, such as the Didipio gold mine, and the closure of 23 mines, including several nickel operations.

Lopez, who has been a vocal opponent of the impact mining has on the Philippines environment, explained the move was about putting the public’s welfare ahead of mining revenues.

“My issue here is not about mining, my issue here is social justice,” Lopez said.

In an ASX announcement, OceanaGold said it had not yet received any formal suspension order from the Philippines department of environment and natural resources (DENR), and that mining and processing activities were continuing at the Didipio mine.

The company added that there was no legal basis for the proposed suspension, as the mine did not violate any laws, rules or regulations, and was not posing any threat to public, security, health, safety or otherwise.

OceanaGold chief executive officer Mick Wilkes said the decision was unjustified nor had any basis in law.

“We have not received any show cause notice from the DENR nor have we received a suspension order. Should we ultimately receive a suspension order as suggested today (February 2) we have very strong legal grounds to have it overturned,” Wilkes said.

“Our Didipio mine is a partnership with the Government of the Philippines through the Office of the President and has a strong social license to operate. We are a large employer of Filipino nationals, and our operation delivers significant benefits to the local communities.

“As proof of this, Didipio was announced as the joint winner of the presidential mineral industry environmental award in recognition of our exemplary performance in safe and environmentally responsible mining.”

OceanaGold produced 147,150 ounces of gold at Didipio in 2016, it announced on Monday.

While the plan to close or suspend the mines is bad news for companies operating in the Philippines, like OceanaGold, it could be the opposite for nickel miners producing in Australia.

In 2015, the Philippines was the world’s leading nickel producer with 530,000 tonnes. By shutting down its nickel mines it could reduce the country’s output by as much as half.

The share price of Australian nickel miner Western Areas increased by 10.9 per cent on the ASX yesterday following announcement of the proposed move. The three-month nickel price on the London Metal Exchange (LME) also jumped to a three-week high of $US10,500 a tonne.
