Geoscience Meets AI: Imagining Tomorrow’s Possibilities

Mary-Anne Hildebrandt, P. Geo., FGC Energy and minerals power our lives, and while we Canadians live in a land of abundance, global projections of natural resource consumption far exceed what is readily available. Economic geologists are increasingly challenged to locate near-surface mineral resources that are feasible to extract. Today’s evolving business models focus on creating more precise, surgical methods of extraction, not only to reduce the environmental impact of mining, but also to unlock economic potential in deposits that, in the past, would not have met the threshold for Reasonable Prospects for Eventual Economic Extraction (RPEEE). In parallel, we are working in the era of Big Data. In 2020, NASA reported that its Earth Science data collection had reached 40 petabytes (PB), a unit 1000 times the size of a terabyte (TB) and that this collection was expected to expand to 250 PB within six years. Geoscience data in the mineral and mining industry follows a similar trend. Big data and increased complexity of the deposits make it essential that Professional Geoscientists (P. Geos) leverage Artificial Intelligence (AI) because traditional methods of analysis are often insufficient to handle the scale and complexity of modern datasets. There are many companies and software developers trying to deliver solutions that produce high-quality results in real-time such as geochemistry, mineralogy, and structural measurements collected and analyzed in real-time at a drill rig using either powerful downhole tools or field core scanners. Some experts in the field believe that these advancements may reduce the necessity for geoscience professionals; however, it is far more likely that AI will strengthen our ability to understand, analyze, and model vast amounts of data, giving us insights that would otherwise be unattainable in a short amount of time. Consider society’s approach to earthquakes and how advanced we have become in creating predictive models over the last century. There are AI applications in use today that allow P. Geos the ability to analyze large datasets that aid in the creation of robust, predictive models. These detailed models allow P. Geos to have a better understanding of risk to the public and offer greater guidance to inform early warning systems. By integrating AI into our professional toolkit, we will be able to make more informed decisions, streamline complex analyses, and better allocate limited resources.  Professional regulators, such as Professional Geoscientists Ontario (PGO), also stand to benefit from AI. For example, AI could be used to identify patterns and anomalies that would allow regulators to detect unethical behaviour more effectively. Rather than waiting for another Bre-X-type incident, where a company reported falsified assay results that inflated the gold reserves to attract investors, it is in the public’s best interest for our profession—and its regulators—to develop advanced tools to stay ahead. It is certain that bad actors will also leverage AI to attempt to bypass existing legal frameworks, making it essential to reinforce our defences. However, as powerful as AI is, its use must be carefully guided. As a profession, we bear the responsibility to harness AI in ways that ensure its development and applications remain ethical, transparent, and fair. We need greater dialogue and a robust framework to guide this evolving area. Inherently, AI lacks an understanding of ethical intentions. It makes decisions based on the algorithms and code designed by humans, as well as the dataset on which it is trained. However, developers have the ability to instil AI with ethical or unethical subroutines either intentionally or unintentionally. Developers might choose to design it with an underlying malicious intent, such as spreading misinformation, or creating harmful automated decisions that negatively affect individuals, groups, or the natural world. Unintentional biases could also emerge if the AI is trained on a limited or biased dataset, leading to skewed decisions or outputs. For example, a mining company using AI to identify mineral exploration targets might train the system on a flawed dataset that lacks sufficient diversity in the geological dataset used for training. As a result, the AI could misunderstand key aspects of the mineralization controls if its training dataset is incomplete or biased. This could lead to the AI relying on surface-level features like rock type or mineral traces that resemble those found in resource-rich areas. However, without accounting for other critical factors such as depth, geological history, geochemistry, alteration, or other favourable conditions needed for mineral formation, the AI might incorrectly predict the presence of valuable deposits in barren areas. This misinterpretation could lead to the company and its shareholders to invest millions in unproductive exploration, wasting time and money. Meanwhile, the AI might overlook other areas with better prospects due to the skewed training dataset. Without the critical and well-trained eye of a P. Geo. guiding AI and validating its outputs, AI has the potential to cause not only financial losses, but also unnecessary environmental damage. PGO’s Code of Ethics calls on P. Geos to demonstrate “integrity, competence and devotion to service and to the advancement of human welfare”, and it is imperative that AI systems embody these principles as part of the original code. Responsible integration of AI is critical to upholding the public’s trust in our profession, and a balanced approach is needed to ensure that we seize opportunities while safeguarding the public and the natural world from harm. After using the wrong ingredients to bake a cake, Anne Shirley reflects “…isn’t it nice to think that tomorrow is a new day with no mistakes in it yet?” (Anne of Green Gables, Ch. 21, by L. M. Montgomery). In the age of AI, geoscientists must remain committed to continuous learning and ethical practice. AI will inevitably become more integrated in our daily activities. To ensure that AI has the right ingredients that will prevent harm to society or the natural environment, we need greater discussion and more collaboration with each other and our peers in data science to build a framework that guides the use of AI in geoscience practice. A proactive approach focusing on the development of an

Geo Careers: Mary-Anne Hildebrandt

What is a career? Merriam-Webster defines career as “a profession for which one trains, and which is undertaken as a permanent calling.” With more workplaces embracing the idea of flexibility, the weight of words like “permanent” and “calling” evoke something else entirely. Career originates from the Latin carrus, as in a wheeled cart, which some interpret to mean chariot (Online Etymology Dictionary, n.d.). It sounds a great deal more epic than logging into a laptop for another Zoom call. Imagine you and your coworkers embarking on a journey in chariots each day. Surely, with that as your vision, nothing is out of reach. So, what do you do for a living? It’s a common question for any social gathering, and yet, my answer is met with surprise. People are surprised to learn that I am not a teacher or nurse or some other career that matches their perception of who I am. No one has ever guessed that I am a geoscientist. Why? Do I not look or sound like a geologist? This encounter is not exclusive to the public. In truth, I’ve even been mistaken for an administrative assistant when standing in my office wearing head to toe safety gear surrounded by rock samples, and that’s not to say administration staff don’t do field work. They most certainly can and do! It’s that everyone carries bias, and when no other information is available, we fill in the missing data with assumptions based on our own perceptions of the world. Even recently at PDAC, I was asked if I was there as a member of the media, and not a geologist. Who knew that you could work in an industry for 17 years and still feel at times that you don’t quite fit other people’s perceptions of your job title. Every day there are lessons, and some are only learned much later.  When I left university for my first summer field position in 2006, I intended to return for a Master of Science, but looming student debt and other family obligations drove me to stay in the industry. I dreamed about continuing to hone my skills in the areas of geoscience that I enjoyed. Early on, I had a conversation with a manager of a team I wanted to join about my career aspirations, and he tried to put an end to those dreams. He explained that no company would invest their finite resources to support my development in this field because I was a woman, and at the age of 25, I was too old. In his experience, it wouldn’t be long before I would marry, have children, and pursue a different career. I left that conversation feeling devastated because this manager was someone that I truly respected. At the time, I didn’t know how to challenge the underlying beliefs and assumptions that he had conveyed about me. I questioned whether saying anything at all would make a difference. Who was he to decide what my future would hold? That evening, I resolved to not let his ignorance define me.   Did you stay in Geoscience? I have had the good fortune to have worked in the field of geoscience since graduating and successfully achieved my designation as a Professional Geoscientist (P.Geo.) in 2017. Drilling, sampling, mapping, and modelling led me to a deeper understanding of the influence of geological processes, sample bias, and error within spatial models and mineral estimates. In addition, the depth and breadth of the technical projects I have been able to work on has increased not only my technical skills but also my leadership skills. After working for several years as the person performing the annual reconciliation for Mineral Resources and co-authoring the technical report on the resource, I was appointed to carry out the duties of Competent Person (as defined in the SAMREC and the JORC codes) for the deposit I had spent years mapping and modelling. A Competent Person is responsible for preparing the technical report used for public disclosure of a Mineral Resource and Reserve. In the Canadian context, a CP would be similar to a Qualified Person or QP under the National Instrument 43-101 Standard. CPs, like QPs, are considered to be competent to sign-off because they meet or exceed the knowledge requirements and have enough time working in a particular commodity, like gold. There are other requirements, and for those working in the industry, it is best to be well-versed in the governing code or standard for your jurisdiction. It’s an incredibly important responsibility that cannot be taken lightly, and I was honoured to know that those in power trusted my capabilities to appoint me into that role. Although I enjoy the technical aspects of my work, I have found mentoring and coaching others to be equally, if not more, rewarding. My career has carried me to remote areas across Canada and even overseas to Botswana and South Africa. I am forever grateful to have been mentored and supervised by professionals who are highly respected in their field. These are the people who saw the value I could add to a team and a project, and they were instrumental in why I stayed the course. I found professionals from all disciplines were always there to lend a hand or an ear to help find a solution to the latest problem.  One project that I had been assigned was to create a spatial estimate for a stockpile. This was not the norm and fell outside of our regular workflow. A stockpile is not an in-situ deposit. To use it in a business plan, my work still needed to answer similar questions that would be asked during mineral classification of an in-situ deposit. There are a number of factors involved in this work, but to keep this brief, these are the types of questions that needed to be considered: How did the mining team place the rock? Do we have confidence in the volume of the stockpile? How was the volume measured? At what frequency was the volume measured? Do
