Machine learning has proven a successful tool in expanding the exploration search space into new frontiers and refining areas for follow-up exploration.<\/em><\/p>\n\n\n\n Artificial intelligence (AI) could transform mining exploration this decade, enabling companies to analyse larger datasets and develop new geological insights.<\/p>\n\n\n\n That\u2019s the view of Ben Jupp and Stephen Johnson, respectively principal and senior geologists at SRK Consulting, an international resources consultancy.<\/p>\n\n\n\n They believe machine learning in mineral exploration, while still an emerging technology, will become more widespread as miners and explorers use algorithms to test and refine geological concepts currently applied to exploration.<\/p>\n\n\n\n One key area in particular is the application of AI in prospectivity analysis, an area which SRK has recently seen success.<\/p>\n\n\n\n \u201cI\u2019m an absolute convert to using AI in mineral exploration,\u201d Johnson said. \u201cI\u2019ve seen the benefits of using machine learning first-hand through a number of recent projects. The results have been incredibly powerful.\u201d<\/p>\n\n\n\n For Jupp, the key is integrating AI with existing knowledge-driven exploration approaches.<\/p>\n\n\n\n \u201cEssentially, AI allows us to integrate deep technical knowledge about a particular terrain and mineral system into a set of critical inputs to provide a machine learning algorithm,\u201d Jupp said.<\/p>\n\n\n\n An advantage of using AI in prospectivity analysis is the rapid integration and analysis of large datasets by machine learning.<\/p>\n\n\n\n \u201cUsing training data such as known mines, machine learning can identify patterns and relationships in the data that geologists might overlook with traditional approaches,\u201d Jupp said.<\/p>\n\n\n\n \u201cOften, exploration companies will pay a highly knowledgeable expert to assist with their exploration targeting and narrow down their exploration efforts. With AI, we can use that knowledge, insight and human expertise to map out critical targeting elements and feed this into the machine learning to analyse and make predictions.\u201d<\/p>\n\n\n\n AI is especially powerful for small and mid-sized mining companies that need to analyse large volumes of data cost effectively.<\/p>\n\n\n\n \u201cFor junior explorers with a package of tenements and limited capital, the ability to narrow exploration targeting is crucial,\u201d Johnson said. \u201cAI can help do that and potentially find new value in tenements that have been overlooked or are a lower priority.\u201d<\/p>\n\n\n\n AI also removes human biases and assumptions in exploration targeting.<\/p>\n\n\n\n \u201cA consistent theme in exploration projects is people being drawn to certain areas based on existing data and preconceived ideas,\u201d Johnson said. \u201cWith AI targeting, you\u2019re feeding the available data and geological layers into a model to develop a holistic view of the prospectivity of a tenement package.<\/p>\n\n\n\n \u201cThere\u2019s no bias or subjectivity about where you should be exploring beyond what the data is suggesting.\u201d<\/p>\n\n\n\n AI projects underway<\/strong><\/p>\n\n\n\n SRK\u2019s interest in AI emerged around 2019. Jupp and Johnson were part of a team of Australian and Canadian SRK Consulting experts who competed in OZ Minerals\u2019 Explorer Challenge, a prominent competition that attracted more than 1000 participants from 62 countries.<\/p>\n\n\n\n The SRK Consulting team won the Fusion Prize after reinterpreting and adding value to existing datasets by applying data-driven machine learning to guide a set of knowledge-driven, mineral-system-informed fuzzy inference solutions. The result was three highly ranked iron-oxide copper gold (IOCG) targets and seven secondary targets.<\/p>\n\n\n\n In 2021, SRK began applying these and other machine-learning techniques to help companies reduce their exploration targeting at brownfield and greenfield sites.<\/p>\n\n\n\n SRK has a global partnership with DeepIQ, a leading US developer of generative AI in the oil and gas, utilities and mining sectors. SRK experts have integrated DeepIQ algorithms into their mineral prospectivity analysis at some projects.<\/p>\n\n\n\n SRK has also recently applied machine learning to exploration projects in several regional project areas, including Australia, South America and Europe, with good results.<\/p>\n\n\n\n \u201cThere\u2019s a lot of work underway at SRK globally to test and apply AI methodology for mineral exploration,\u201d Jupp said.<\/p>\n\n\n\n Knowledge-driven targeting<\/strong><\/p>\n\n\n\n SRK\u2019s work with machine learning builds on its work in prospectivity analysis using more traditional knowledge-driven approaches for developing prospectivity maps. Methods such as fuzzy logic in mineral prospectivity analysis aim to quantify intricate relationships between geological attributes to define mineralisation potential.<\/p>\n\n\n\n \u201cThe main aim of the prospectivity analysis process is to assist our clients to narrow the focus area for exploration prior to field-based exploration, ideally as specific as the prospect area and even drill target areas,\u201d Jupp said. \u201cOne of the key benefits of this method is you\u2019re not reliant on the availability of training data when compared to machine learning methods.\u201d<\/p>\n\n\n\n SRK recently applied fuzzy logic targeting on a project for Astute Metals, an ASX-listed resource company. Astute holds an 80 per cent interest in the Georgina Basin IOCG project in the highly prospective east Tennant province of the Northern Territory.<\/p>\n\n\n\n \u201cWe were successful in identifying several promising target areas in the undercover extents of east Tennant Creek,\u201d Jupp said. \u201cRecent drilling by the client at one of these targets intercepted strong indications for IOCG-style mineralisation that will be followed up with additional drilling to be completed later this year.\u201d<\/p>\n\n\n\n In the Middle East, Johnson has used fuzzy logic processes for exploration targeting.<\/p>\n\n\n\n \u201cThrough our fuzzy logic approach, we developed a prospectivity model that we followed up with systematic fieldwork to validate,\u201d Johnson said. \u201cThe outcome was fantastic because the fuzzy logic results were able to be tested and refined during follow-up phases of field work, with some really encouraging results.\u201d<\/p>\n\n\n\n Bright future for AI<\/strong><\/p>\n\n\n\n Jupp and Johnson believe industry hesitance towards using AI in exploration will fade as more results are proven.<\/p>\n\n\n\n \u201cSome explorers have resisted the technology due to concerns that AI could overlook critical steps in the discovery process, but that will change as the industry sees meaningful exploration results from AI,\u201d Johnson said.<\/p>\n\n\n\n \u201cWe\u2019ve been getting a lot more enquiries on AI in exploration as interest in this area builds.\u201d<\/p>\n\n\n\n Longer term, Johnson likes AI\u2019s potential to challenge exploration \u201cdogmas\u201d.<\/p>\n\n\n\n \u201cThe mining industry has traditionally been influenced by certain dogmas about how and where exploration should be undertaken,\u201d he said.<\/p>\n\n\n\n \u201cThen occasionally someone makes a significant discovery that challenges this dogma and there is a rush to embrace new thinking. That will be true of AI this decade as it contributes to significant new mineral discoveries, and some early adopters are big winners from the AI revolution.\u201d<\/p>\n\n\n\n Key considerations for AI and exploration targeting<\/strong><\/p>\n\n\n\n Stay abreast of latest trends:<\/strong> AI technology in mineral exploration targeting is moving rapidly. New algorithms are being developed and tested, and more projects overseas are implementing the technology.<\/p>\n\n\n\n Be open minded:<\/strong> Because it challenges traditional approaches to exploration targeting, AI has been met with some resistance, despite the technology\u2019s successful use in the oil and gas sector. View AI as another tool to complement and add to existing geological processes, not replace them.<\/p>\n\n\n\n Access to AI resources:<\/strong> There is only a small group of experts globally who are skilled in mining geology and implementing and interpreting AI-driven data models. Ensure your organisation has access to internal or external resources with knowledge of the latest AI technologies for exploration.<\/p>\n\n\n\n Understand how AI can be used:<\/strong> A mineral explorer could use AI to understand the critical elements that control the location of a nearby mining operation and map out areas in their tenement holding that display similar characteristics.<\/p>\n\n\n\n Focus on data:<\/strong> Like all data-driven models, AI is only as good as the data it analyses. Ensure data being fed into AI models is high quality and based on a clear understanding of the mineral system under investigation.<\/p>\n\n\n\n Use an iterative approach:<\/strong> For some companies, the value of AI is to test data collected from drilling or other exploration, and used to refine and test prospectivity models in an interactive fashion. In this way, AI is a tool to validate existing geological work by providing another layer of analysis.<\/p>\n\n\n\n Communication:<\/strong> Consider how the organisation will communicate the use of AI to internal and external stakeholders. Reporting of AI-generated exploration results could become a bigger issue for listed mining companies over time.<\/p>\n\n\n\n SRK Consulting is a leading, independent international consultancy that advises clients mainly in the earth and water resource industries.
