Renewable power on its way to Antofagasta’s Centinela mine

Antofagasta has signed a new power purchase agreement (PPA) with ENGIE Energía Chile SA that will see 100% of the power supplied to its Centinela copper operation, in Chile, come from renewable sources.

The contract, from 2022 until 2033, will replace two existing PPAs Antofagasta had in place that expire in 2026 and 2027. It will also see the company sell its indirect 40% interest in the Hornitos thermal power station to ENGIE, resulting in an attributable post-tax write down of some $43 million, it said.

After the write down, this new renewable energy contract will be value accretive as power costs will be significantly reduced in stages from 2020 onwards, Antofagasta noted.

Antofagasta’s CEO, Iván Arriagada, said: “With the completion of this agreement, from 2022, all our mining division’s power will be from renewable sources, and at a lower cost as well. This is an important step in achieving our target to reduce our carbon emissions by 300,000 t by 2022.”

Wenco fleet management solution to monitor, control production at Antofagasta’s Centinela

Thiess has chosen the Wenco Mine Performance Suite to run its operations at Antofagasta’s Centinela copper mine in northern Chile.

Centinela sits 1,350 km north of Santiago in the Antofagasta Region of Chile. Antofagasta Minerals has contracted Thiess, the world’s largest mining contractor, to develop the Encuentro Oxides pit, which will contribute to the mine’s production of 50,000 t/y of copper cathode for a planned lifespan of 15 years.

To monitor and control this production, Thiess is leveraging the Wencomine fleet management system. The system will optimise productivity and efficiency across the pit’s 56 active units, including 12 high-precision loading units and five high-precision drill rigs, according to Wenco.

Wenco’s data solutions are designed to boost productivity, decrease operating costs, extend equipment life, and give mining companies actionable insights into their operations. Its Mine Performance Suite consists of systems for fleet management, high-precision machine guidance, predictive maintenance, collision avoidance, and mining business intelligence.

Unlike other solution providers, Wenco, a Hitachi Group Company since 2009, has designed its systems with an “open systems philosophy” that, it says, “empowers customers to freely integrate systems to support their unique business processes, data requirements, and reporting needs”.

Thiess chose Wenco for its reputation in delivering strong production functionality and a streamlined implementation process with minimal impact on day-to-day mine operations, it said.

Wenco said: “Expanding the business relationship with Thiess in South America is strategically important for Wenco as well. Contractor-operated sites are common throughout the region and they stand as a significant growth market for the company. Likewise, contractor partnerships form a key part of the open and interoperable ecosystem of partners pushed by Wenco and its parent company, Hitachi Construction Machinery.”

Wenco Regional Manager — Latin America, José Eugenio Saravia, said: “We’re very pleased to implement the Wenco Mine Performance Suite at the Encuentro Oxides development.

“Wenco has worked with Thiess at various mining developments around the world and our solutions are ideal for the productivity improvements and ease of deployment they require. We’re looking forward to a long and profitable business together.”

This sale is another boon to Wenco in the region, following recent sales to Chinchillas and Pucamarca mines and a new partnership with Brazil mining solutions provider Tecwise.

“Contractors like Thiess are a major growth area for Wenco and the industry as a whole. We’re seeing a great many more opportunities of this sort throughout Latin America,” Saravia says.

“As well, we’re seeing more and more customers excited to partner with a Hitachi-owned company like Wenco, who can deliver the reliability and support only available from a major OEM and global mining leader.”

Antofagasta backing ‘digital transformation’ of operations

Antofagasta, in its 2018 financial results, has promoted its innovation focus, saying it is critical to creating long-term value and being “a key enabler of safe, sustainable competitiveness and growth”.

One of the ways the company is seeking innovative solutions is through the increased use of data and technology, which it calls “the digitalisation of operations”.

Antofagasta said it is investing significantly in this area, which has an implementation budget of $40 million, to strengthen its technological platform, including critical operating systems and connectivity.

The company has also applied advanced data analytics at its processing plants to better understand and improve their performance.

In the meantime, it said work was underway on the design of a Remote Centre that will allow integrated operations management at its Centinela operation in Chile. Service provider Wood is currently preparing a prefeasibility study for this technologically-advanced integrated operations centre, which includes cloud data storage and information management for its operations, easily accessible from anywhere in the world.

Antofagasta continued: “It’s not just at the operating level that there are benefits of improved data.

“Los Pelambres constantly monitors its tailings deposits and, as part of the Programa Tranque project, expects to start releasing the monitoring results online early next year. This will provide the community with real time information, helping to build trust between ourselves and our neighbours,” the company said.

Programa Tranque contemplates the development of an online monitoring system of tailing deposits to transmit, process and broadcast, in a user-friendly way, updated physical and chemical indicators of the deposits.

It incorporates the best available technologies and innovative mechanisms for the measurement of critical parameters and variables, as well as an information management platform to communicate information to authorities, mining companies, and the community, allowing an early warning system to be activated ahead of potential emergency situations.

In addition to Antofagasta, BHP and Codelco are partnering on this five-year programme that seeks to position Chile as the leading country in information transparency related to the performance of its tailing deposits.

Thiess builds on South America first with Antofagasta contract extension in Chile

CIMIC Group’s global mining services provider, Thiess, has been awarded a A$420 million ($303 million) contract extension by Antofagasta Minerals (AMSA) to continue operations at the Encuentro open pit in northern Chile.

Thiess will continue to provide mining services for another four years as part of the contract with a scope of works comprised of drilling, load and haul, mobile equipment maintenance and mine services.

The original 2015 contract with AMSA was Thiess’ first in South America.

Douglas Thompson, CIMIC Group Executive Mining and Mineral Processing and Thiess Managing Director, said: “Since commencing operations in 2015, we have moved over 70 million cubic metres, a first for Thiess in South America. This has been possible through the team’s focus on efficiency and productivity and working collaboratively with our client.”

Planned future improvements at the mine include investment in maintenance infrastructure, a fleet management system and transfer to Thiess of short-term mine planning responsibilities, CIMIC said.

Earlier this month, the Thiess Centinela operation was announced as winners of the ‘National Geology and Mining Service Award’ for safety performance by the Chilean government.

The Encuentro Oxides deposit came into production at AMSA’s Centinela mine in the last quarter of 2017. It is expected to produce an average of approximately 43,000 t/y of copper cathode over an eight-year period, using the existing capacity at Centinela’s SX-EW plant.
