Driving out capital expenditure and standardising IIoT infrastructure have been the two key pillars propelling Maestro Digital Mine forward, and, 10 years after its formation, these two drivers are on show with its latest launches at the SME MineXchange Annual Conference & Expo in Salt Lake City.

Over the last decade, the company has become synonymous with improving underground mine ventilation safety as well as reducing blast re-entry times, with an offering that includes air quality stations, automated regulators, and “fail-safe” LED displays. Yet, Maestro’s core is IIoT devices and last mile digital networks for underground mines.

Michael Gribbons, CEO and Co-founder for Maestro, says the company’s production of “IIoT solutions” pre-dates the popular use of this acronym, with its big launch in Salt Lake City set to take Maestro into new “edge-based” territory that will allow it to cope with multiple communication protocols or artificial intelligence-led process miners look to leverage over the next decade.

He explained to IM: “We have re-envisioned and redesigned both our hardware, embedded firmware and external software to allow greater flexibility and capabilities for today and the future; the platform, if you will.”

This current hardware platform has, among other things, underpinned the success of its Vigilante AQS™, which was created to solve applications for mine ventilation monitoring and control.

“Every year, Vigilante customers kept asking for different capabilities, and we have said yes to these requests until we couldn’t.” Gribbons said. “We ran out of hardware space – we just couldn’t do the things the clients were asking anymore, forcing a major platform redesign that is now shipping.”

This constant cycle of improvement has already led Maestro into the realm of dust monitoring and regulator control. It also saw the company devise products and solutions that eradicated the need for expensive PLCs, customer panels and fabrication. Its plug-and-play philosophy, in turn, has reduced the amount of engineering required to install and monitor these solutions.

“For example, legacy analogue actuators are now being driven out of the equation by coupling ModuDrive™ actuators to automate regulators allowing significant capital expenditure reductions and improved diagnostic monitoring by using edge-based embedded IIoT technologies,” Gribbons said. “The mining industry is following other industries by applying modular construction where proven solutions can be selected and applied instead of the typical one-time custom engineering design and build where individual components are collated and customised on an individual basis. The main advantages of applying modular construction is schedule acceleration and capital expenditure reduction.”

Gribbons sees the new platform – a combination of hardware, user interface, on-premise and cloud-based software allowing data to be stored and trended by the customer as they choose – being able to take advantage of “true edge-based technology” to make better and quicker decisions.

The new platform installed on the Vigilante AQS, SuperBrite™ Marquee display, MaestroFlex™ regulator and ModuDrive actuator are on display at the SME conference.

Looking past the fixed automation infrastructure Maestro has made its name on, the company is now embedding its expertise into more mobile solutions that the industry has been taking a liking to, namely drones and unmanned robots.

Also featured on the Maestro stand – and the Exyn Technologies stand – at the event is an aerial drone with a Maestro gas monitoring IIoT device fitted on it.

This new gas monitoring drone, which will integrate critical gas sensors onto the ExynAero™ and ExynPak™ platforms, is, effectively, the “quickest and safest mobile gas monitor on the planet”, Gribbons remarked. “The drone is able to automatically launch and log targeted gases directly on the point cloud in any confined area without deploying mine rescue personal with Scott Air-Paks. Again, we are improving worker safety and accelerated time to obtain accurate data in emergency conditions or for more granular data at the headings for reducing blast re-entry times.”

Powered by ExynAI’s multi-sensor fusion capabilities, gas sensor readings are captured while the robot is in flight and displayed in real-time via a ruggedised tablet, Exyn explained. These sensor readings are saved with precise coordinates in a high-fidelity point cloud that can be exported and examined in a variety of mining software.

These mobile applications will remain a minority interest for Maestro, but it offers the company another way to influence the underground mine safety dynamic and ensure it stays loyal to its “we leave no one stranded” brand promise.

Such collaborations are nothing new for Maestro. Just last year, it teamed up with Howden to integrate its IIoT solutions into the Ventsim CONTROL ventilation optimisation software, while, in 2020, it brought the Plexus PowerNet™ last mile communication network to MacLean Engineering’s Sudbury test mine and Dynamic Earth’s educational mine to enable continuous connectivity underground.

Gribbons said the company has also just worked with Spain-based Zitron on designing large 4 x 4 m MaestroFlex™ regulators on underground booster fans at a major gold mine in Canada.

All these partnerships are part of the company’s recipe for success.

“We’ve progressively eliminated elements of underground mine automation infrastructure to simplify and allow for the future automation of mining,” Gribbons said. “This is working; the clients continue to return, and we stay true to our core purpose of enhancing lives by the pursuit of productivity and safety excellence.”

Maestro Digital Mine’s Latin America expansion is gaining traction, with the Sudbury-based company recently landing sales from major gold mines in Argentina.

Its flagship Industrial Internet of Things measurement and control instrumentation solutions, such as the Vigilante AQS™ and Zephyr AQS™ air quality monitoring stations, and the Plexus PowerNet™ last mile communication platform, are designed to provide the visibility and communication miners require to keep up productivity and improve safety while operating at increasing depths

Having successful launched these products in over 130 mines, in more than 20 countries around the world, Maestro started its strategic outreach and market research in Latin America last year.

Maestro’s says its distribution channels are vital to its success in this area and, as part of the Maestro sales team, provide valuable feedback, access and service to potential clients in Latin America.

This strategy saw it partner with associations that assist with market research and business-to-business meetings, such as the Mine Connect (formerly SAMSSA), and the Northern Ontario Export Program led by the Greater Sudbury Development Corporation (GSDC) and Mining Suppliers Trade Association (MSTA), as well as secure four new distributors/agents in the key mining hubs of Argentina, Chile, Peru and Mexico to support this growth.

This investment is already starting to pay off, with the company recently landing significant contracts across the region.

In Argentina, Yamana Gold’s Cerro Moro mine, in the Santa Cruz province, is installing the Plexus PowerNet solution. This delivers a high speed, low latency digital communication network that provides “PoE+ power” to Wireless Access Points, cameras and any other IP-based device, Maestro said. The system eliminates the need for costly outside fibre optic contractors and can be installed and maintained by any internal tradesperson, according to Maestro.

Cerro Moro, an open-pit and underground gold-silver operation, poured its first gold and silver doré back in May 2018 and, up until recent COVID-19-related restrictions hit mining operations, was expected to produce 117,000 oz of gold and 7.5 Moz of silver in 2020, according to the miner.

In that same province, Maestro has also installed the last mile communication solution at Newmont’s Cerro Negro mine. This operation includes five underground mines (Eureka, Mariana Central, Mariana Norte, San Marcos, Bajo Negro), one open-pit mine (Vein Zone) and one cyanide leach processing facility that yields gold recoveries of 96%, according to Newmont.

In Mexico, Maestro has installed Vigilante AQS – air quality monitoring stations in Peñoles mines. Peñoles, a subsidiary company owned by Grupo BAL, is the second largest Mexican mining company, the top Mexican producer of gold, zinc and lead and a world leader in silver production.

Coeur Mining has, meanwhile, installed and integrated the Vigilante AQS and MaestroLink software into its Mexican mines. This includes the Palmarejo silver-gold complex. The miner continues to expand Maestro’s digital solutions on each new level of its Mexico mines, Maestro said.

Maestro concluded: “With the support of our distribution partners, we are proud to be enabling worker safety and productivity in the mines of Latin America. It is through a collaborative model that Canadian suppliers can impact positive change in the global mining industry.”

Maestro Digital Mine has used the backdrop of the CIM Convention and Exhibition, in Montreal, Quebec, to launch its latest digital industrial internet of things (IIoT) solution, the Zephyr AQS™.

Maestro’s Zephyr AQS is a compact, low cost environmental air quality monitoring station for underground mines. It is an IIoT device that connects directly to an industrial network without the requirement of adding an expensive and complex programmable logic controller (PLCs) and several analogue-based instruments, the company said.

“Since it is a digital device, not only are the real time environmental conditions reported back to surface via a single ethernet connection, but all the advanced diagnostic data is available too, assuring maximum uptime,” Maestro said.

Michael Gribbons, Vice President Sales and Marketing, Maestro Digital Mine, said at the launch event: “The Zephyr AQS was developed to satisfy 75% of all the air monitoring requirements of a modern mine. Airflow rate, airflow direction, gas levels, barometric pressure and wet/dry bulb temperatures can be measured in real time and, now, affordably.

“The Zephyr AQS is designed for any mine aiming to increase production, improve miner worker safety and reduce energy by monitoring and controlling ventilation air in an underground operation. The first step of working to control ventilation is the requirement of measurement. Only then can you start to understand and drive value to increasing production by getting the miners back to the face quicker and safer. Or, reducing the energy demand by providing enough ventilation air to the areas of the mine that need it and reducing air to the non-working areas of the mine.”

Like all Maestro solutions, the Zephyr AQS is a fully digital solution that can be plugged into a network switch without the requirement of PLCs, PLC cabinets and all the associated wiring, terminations, software and complex labour for integration into the network, the company said.

“Based on direct customer feedback, Maestro’s digital products save mining companies, on average, 40-60% of capital expenditure compared to conventional monitoring solutions,” Maestro said.

“All Maestro solutions are provided with lifetime, free firmware updates. The full savings to mining clients is in the range of 70-80% over the full life cycle with no hidden hooks or costs to bear in the OPEX maintenance cycle.”

The new Zephyr AQS air quality station features three fully configurable sensor inputs that can be freely mixed and matched according to the customer’s requirements. Like the Vigilante AQS™, the Zephyr AQS will be configured through built-in webpages similar to that of a home network router, according to the company.

All the sensors connected to the Zephyr AQS electronics are digitally supported by the way the Zephyr AQS communicates over the mine’s network using standard network protocols. Maestro fully supports both of the two most popular network communication protocols – Modbus TCP/IP and EtherNet/IP™. Alternately, the Zephyr AQS offers on-board analogue outputs (3 x 4-20 mA) and two relay outputs to tie into legacy systems.

David Ballantyne, Vice President of Development and Technology, Maestro Digital Mine, said: “The Zephyr AQS is considered the baby sister of the Vigilante AQS. Both provide plug and play sensors and both are fully digital. However, the Vigilante AQS supports seven plug and play ports versus three for the Zephyr AQS. The Vigilante AQS also provides four complete Proportional – Integral – Derivative control loops to allow it to run autonomously in the event of network failure. It can also integrate up to 24 RTD sensors used in primary fan and booster fan applications.”

The Vigilante AQS was created to solve 100% of the applications for mine ventilation monitoring and controlling, Maestro said, however solving all the applications with a single device adds extra costs for most of the simpler requirements.

Maestro has supplied over 120 mines globally with this equipment. “We recognised that a lighter version would be adequate for many of the mines price sensitive markets such as Latin America and Africa,” it said.

Maestro has 100 units sold, pre-delivery, from three existing hard-rock mining customers in Canada, the US and Spain.
