SBQuantum, an organization creating diamond quantum magnetometers to speed up essential mineral discovery, has partnered with Silicon Microgravity, a developer of inertial and gravity sensors.
With just below $900,000 in funding from the Canadian and UK governments, the companions are making a drone-based system of sensors to quickly determine the situation of mineral deposits, accelerating the exploration course of and offering an emissions-free technique of discovery.
The mission, which is able to take 18 months to finish, represents the primary deployment of a diamond-based quantum magnetometer on a drone. The businesses purpose to deploy the expertise at Glencore’s Raglan nickel mine in northern Quebec subsequent 12 months.
We caught up with David Roy-Guay, CEO and co-founder of SBQuantum, to search out out extra concerning the expertise, its functions and the trail to commercialisation.
Scarlett Evans (SE): Inform us about your expertise – how does it work?
David Roy-Guay (DRG): The quantum machine we’re creating is to do with magnetic discipline sensing.
Earth’s magnetic discipline is in all places, created by the motion of magma on the Earth’s core. This discipline could be altered by any metallic object, so any presence of metallic components has an impact and could be picked up by devices often known as magnetometers.

Our tech is a novel technology of magnetometers primarily based on quantum impurities and diamonds. On the coronary heart of our sensor are artificial lab-grown diamonds, that are made up of carbon and to which we added nitrogen to present it the property of ‘spin’ – mainly turning it into the tiniest magnet you’ll find.
We now have spent the final six years making the tech transportable, so it may be deployed simply within the discipline and even carried by drones to scan the Earth, map its magnetic discipline and determine areas with mineral deposits to steer the mining exploration course of.
SE: How does your expertise evaluate with present exploration strategies?
DRG: Historically, you may use beforehand discovered mineral our bodies to deduce the place ore deposits are, and how much materials is there, earlier than sending in a crew to begin drilling.
Utilizing our sensors, we are able to create a 3D map of the ore physique – what it appears like, how massive it’s, how deep it goes – after which we are able to present miners with extra exact insights on the place they need to drill.
At the moment, groups can map the amplitude of Earth’s magnetic fields, feeding this knowledge into mathematical fashions to create a 3D, on-the-ground image of what the ore physique appears like. Nonetheless, amplitude knowledge may be very restricted data, and can give a whole bunch of attainable maps.
We’re creating not simply the one sensor but additionally an array of sensors to offer nine-times extra exact magnetic discipline maps. From this, we are able to have a greater understanding of what’s shallow, what’s deep, and feed these as constraints into the mathematical mannequin, in order that we are able to actually go from 100 solutions to 1 or two.
Utilizing drones to deploy the sensors additionally makes this technique of surveying extra accessible and fewer invasive than present strategies.
Present sensors to create these maps require large cooling gear, making them extremely tough to deploy at a mine web site. Our tech is essential in that it combines magnetic and gravity sensing right into a single resolution.
SE: How is your mission with Silicon Microgravity advancing the tech?
DRG: By our collaboration with Silicon Microgravity, we’re capable of combine gravity sensing into the platform. So they’re offering all of the gravimetry experience – measuring gravity fields.
Magnetometry will let you know concerning the geology – what sort of supplies are within the floor – after which gravity can let you know if the fabric within the floor may be very dense. Utilizing this data, you’ll be able to derive exploration insights into what sort of ore is within the floor.
Measuring Earth’s magnetic discipline fluctuations can provide you one piece of knowledge, however not the entire image. If there’s a excessive gravity discipline, then which means there’s something very dense, like iron. So actually fusing these two sensing modalities collectively, then we are able to get higher insights to steer exploration.
SE: What stage is the mission at now?
DRG: We now have accomplished a number of pilots, so we’ve got taken the tech out into the sector. The target of this mission is to maneuver in the direction of sturdy deployment, so creating the magnetometers to be tremendous compact and correct.
We’re at present on the integration part with Silicon Microgravity, however the purpose is to be within the discipline in northern Quebec on the Glencore mine web site Raglan by subsequent 12 months, the place they’re mining for nickel.
We can be utilizing these gravity and magnetometer measurements to supply novel varieties of maps and correlate this with the coaching knowledge they’ve, so we are able to predict the place to develop their mine.
SE: Trying forward, what do you see to your sensor tech?
DRG: Down the street, we wish to additionally measure electromagnetics, which conventionally are helicopter-borne. We might purpose to deploy this additionally on the drone platform in order that we are able to map the conductivity within the floor, which gives you much more data on the sorts of deposits within the floor.
We additionally discovered there was a great market alternative within the defence sector, with these sensors having a possible use in submarines to determine objects round them. The opposite software is navigation, offering high-quality mapping capabilities for a spread of navigation devices together with cell telephones. We now have this as an ongoing analysis mission.
These are another functions, however the greatest market we’ve got recognized is de facto inside mining expiration.
