Newmont Goldcorp sees value in expanding process control support hub

Newmont Goldcorp says it plans on expanding its Process Control Operations Support Hub globally following a successful pilot project launched in Australia, in 2018.

The company will start the expansion in Ghana, where its Ahafo, Akyem and Subika mines reside, but expects full implementation in 2020, it said.

The Process Control Operations Support Hub pilot project was launched in 2018 with a mandate to streamline process control systems, procedures and monitoring tools, the company said.

“Thanks to the teamwork and collaboration of our Boddington team, the pilot project was a great success, demonstrating the need for process control support and the value of the project’s innovations,” the company explained. “We learned that the operational support hub model accelerates the advanced process control value at our sites and allows for knowledge and expertise to be targeted in a cost-efficient way.”

The company also found that the demand for operations support hubs was higher than expected, and that introducing this support model would help drive improvement at its sites.

In line with the company’s Full Potential program’s mandate to identify opportunities for efficiency and innovation across our business, the support hub has added $2.8 million in what the company calls “Full Potential value” to date, Newmont Goldcorp said.

Sun shines on Newmont Goldcorp’s sustainability efforts

Newmont Goldcorp has published its 2018 sustainability report, which has shown why the company continues to rank near the top of several indices measuring mining companies’ global footprint.

The company, which completed the acquisition of Goldcorp only last week, shared several insights into its sustainability goals and achievements in the report, with its solar energy success notable.

Last year, the company installed a new solar plant at its Akyem gold mine in Ghana. The 120 kW plant, which has four of Cambridge Energy Partners’ Nomad solar PV trackers included, will power the camp and mess hall during daylight hours, Newmont Goldcorp said.

“It has a 25-year asset life and is redeployable, so it can be disassembled and moved to another location at closure,” the company said.

Initial data has shown measurable cost, environmental and social benefits, according to the gold miner. Over five months, the plant produced more than 75,000 kWh of solar energy, resulting in a reduction of more than 32,000 kg of CO2, it said, adding that the plant is expected to produce energy at half the cost of grid power.

On top of this, the miner said it was negotiating with Ghana’s Volta River Authority on a purchase power agreement for 8 MW of solar power.

In Nevada, US, meanwhile, the company’s Phoenix mine installed solar arrays that will generate a total of 10 kW of power for two wireless communications sites.

Additional solar projects are under evaluation at Tanami (Australia), which completed the construction of a natural gas project recently, and the Merian mine in Suriname, the company said.

These current projects are just some of the initiatives the company has put in place at its operations.

As of the end of 2018, the company said it had reduced our greenhouse gas (GHG) emissions intensity by 11.7% compared with its 2013 baseline. This is around 70% of its public target to reduce GHG emissions intensity by 16.5% (compared with 2013) by 2020. These numbers do not include any data from Goldcorp.

Completion of the Tanami power project in Australia is expected to reduce its GHG emissions intensity over the next two years, the company said. “We also continue to evaluate fuel switching (from coal to natural gas) at our TS Power Plant in Nevada.”

Newmont goes for CEP renewable solution at Akyem gold mine in Ghana

Cambridge Energy Partners (CEP) has announced that Newmont Mining will use its redeployable Nomad solar PV tracker at its Akyem gold mine in Ghana as the US-based company looks to reduce carbon emissions and its energy consumption and costs.

CEP’s Nomad is a prefabricated and redeployable solar generator with single-axis tracking technology. It can be used in a variety of applications and is designed for quick deployment in scalable 30 kW segments.

“Energy generated by CEP’s Nomad is fully integrated into existing electrical networks to create a reliable and sustainable hybrid power system,” CEP said.

Akyem is in the Birim North District of the Eastern Region of Ghana, some 178 km northwest of Accra. It produced 473,000 oz of gold in 2017.

In Newmont’s 2017 sustainability report, the company said it had advanced a 110 kW solar project at Akyem to the contracting phase. This plant would power the camp and mess hall during daylight hours.

CEP confirmed to IM that Newmont has increased this project to 120 kW and four Nomad units had since been installed and commissioned by local staff.

Power is currently supplied to the Akyem mine site by a 161 kV overhead line system that connects Nkawkaw and Kwae and passes through the area. According to CEP, up to 60% of this power is sourced from diesel and other fossil fuel generating plants.

CEP CEO Tom Miller said the company’s vision is to deliver lower-cost energy to all remote mining sites with its Nomad solar technology.

“In addition, the mobility of our solar technology significant mitigates the risks often associated with permanent solar installations,” he said.
