MMH 2026

Drones have become a highly useful tool in mining, providing accurate, up-to-date information on operations quickly, efficiently and safely. Technologies such as photogrammetry, LiDAR and thermography support surveying, volume calculations, mine monitoring, infrastructure inspection and progress tracking, turning captured data into useful information for planning and decision-making. This talk will offer a practical view of the current applications of these technologies, their capabilities and limitations, and the trends that will shape their development. Drawing on my experience as an underground mine surveyor, I will discuss operational automation, data integration into mining workflows, and advances in navigation and data capture in complex environments, including underground spaces without GNSS coverage. The technical perspective will help explain which solutions are available today and what new opportunities are opening up for the sector.

Знакомство с историей горных работ и ключевыми геологическими особенностями одного из важнейших вольфрамовых месторождений на северо-западе Пиренейского полуострова. Льюис покажет жильную и вкраплённую минерализацию в граните и её связь с ним. Он также расскажет о ресурсах и потенциале геологоразведки.

Что происходит, когда начинаешь искать медь… а находишь золото? В Карменесе геологоразведка делает именно это: ставит под сомнение наши первоначальные гипотезы и заставляет взглянуть на минеральную систему с другой стороны. На MMH я расскажу, как систематическая разведка — от геохимии и опробования до бурения — добавляла новые части головоломки и меняла нашу модель: от проекта, первоначально ориентированного на Cu-Ni-Co, к системе, в которой золото неожиданно приобрело важную роль. Ведь разведка — это не попытка доказать, что твоя первая идея была верной. Это умение следовать данным, задавать правильные вопросы и быть готовым изменить модель, когда геология рассказывает другую историю.

Megado Minerals, through Iberian Copper, S.L., is developing two large-scale regional exploration projects. The first, between Navarra and Aragón, covers the entire Oligocene sandstone formation from Los Arcos (Navarra) to Labata (Huesca), extending almost 200 km, targeting copper mineralisation. The second covers an extensive area 40 km long in the foothills of the Iberian System around Cariñena (Zaragoza), targeting copper, silver and antimony mineralisation. Both projects take a broad, systematic exploration approach to identify targets for more detailed investigation, reviving the prospecting spirit of earlier exploration programmes and fitting within the current First National Mineral Exploration Plan.

The Matagami mining district in Quebec, Canada, is entering a new phase of development that combines the restart of historic mining infrastructure, exploration for new resources and the recovery of value from metals that were not exploited in the past. An integrated approach to rediscovering the potential of a district with more than 60 years of mining history.

What happens when a historic underground mine approaches the end of its life, but decades of geological, mining and operational information indicate that potential still exists beyond the current mine plan? And what if an operation still has life ahead of it, but could produce more than its planning suggests? At MMH, I will present a practical methodology applied to a historic underground mine to assess opportunities beyond the current mine plan and determine whether they can support a longer mine life or higher production. The approach combines Unconstrained Model, Deswik.APEX and iterative optimisation to connect geology, mine planning and exploration. It identifies potential beyond the mine plan, quantifies how much can be incorporated into a Mining Inventory, assesses the level of production that can be sustained economically, and determines where drilling should be prioritised to reduce uncertainty. A mine can run out of mine plan before it runs out of geological opportunity. The challenge is to identify that opportunity, demonstrate its value and turn it into a technically defensible plan.

Potash is part of our lives as an important agricultural fertiliser, and Brazil is a major importer. Part of Brazil’s potash production comes from an underground mine. It presents numerous technical challenges, from drilling to geological modelling and production. This presentation will illustrate the challenges of working with horizontal boreholes branching from a main drillhole for geological modelling and KCl grade estimation, while respecting the stratigraphic framework of one of the most beautiful underground mines I know.

How can we obtain the maximum value from a mining operation when we have several mines, multiple mining alternatives and limited resources? In underground mine planning, finding a technically feasible solution does not always mean finding the most profitable one. The mining sequence, resource allocation and decisions about when and where to produce can have a significant impact on the project’s Net Present Value (NPV). At MMH, I will share a practical optimisation case using Deswik.APEX, exploring how to evaluate different planning scenarios and coordinate several mines to maximise the operation’s economic value. Optimising a mine plan is not only about extracting more ore or increasing production. It means making the best decisions about what to mine, when to mine it and how to use available resources to generate the greatest possible value.

I will show how to find out, before investing, whether an ore can be pre-concentrated with XRT sorting, with a focus on the Iberian Pyrite Belt. I’ll cover the three-step testing method, ROKKSTA’s own XRT scanner, and how lab results become a plant design. I will also explain how Asturmine’s geological expertise and ROKKSTA’s sortability testing work together, from the orebody to the sorter.

А что, если последним ресурсом рудника окажется его собственная история? В Коуреле горное дело оставляло свой след на протяжении двух тысяч лет: римская добыча коренного и россыпного золота, железорудные выработки и железоделательные мастерские на палеозойской толще варисской лежачей складки, антимонит Виларбаку и продолжающаяся добыча сланца. На MMH я расскажу, как Геопарк превращает это наследие в развитие. Работа начинается с инвентаризации в ГИС и геологических, минералогических и археологических исследований и продолжается в геотуризме, геообразовании и охране наследия. Ведь когда добыча заканчивается, рудник продолжает рассказывать, как геология определяла ландшафт, расселение и экономику территории.
