around the Mine-to-Mill approach is the essential catalyst for the transformation of Latin American mining. The main conclusions are: - Blasting consumes only ~2% of total mine energy, yet directly conditions comminution efficiency (37–53% of the total). This energy asymmetry, low energetic cost at the cause, high energetic impact at the effect, makes blast design the highest financial and environmental return intervention available to the mining engineer; - The quantified evidence from the literature is robust and consistent: reducing X80 from 500 to 120 mm increases plant throughput by 20% and reduces energy consumption by 29%; substituting ANFO with a higher-energy explosive reduces comminution consumption by 7.07% and emissions by 2.44 g CO₂/t; and blast redesign for micro-fracture induction can reduce the effective Work Index by up to 30%. These gains carry a direct and measurable sustainability dimension: every percentage point reduction in comminution’s electrical energy consumption — which accounts for up to 53% of total mine energy and ~3% of global electricity, translates into tonnes of CO₂ avoided per year, without equipment replacement, asset expansion or any increase in capital costs. Optimised blasting is therefore one of the lowest-cost, highest-environmental-impact interventions available to the mineral industry to meet ICMM decarbonisation targets and ESG commitments to investors and communities; - In Latin America, which holds ~40% of global copper and ~35% of global lithium, and where energy represents approximately 33% of mine operating costs, the full implementation of the Mine-to-Mill approach can generate savings in the order of tens to hundreds of millions of dollars per year and substantial reductions in CO₂ emissions, without expanding assets or replacing equipment; - Innovative Education in rock blasting, structured around Education 4.0 principles and oriented towards the pit-to-plant system, is the essential and irreplaceable catalyst for this transformation. The proposed framework, with five integrated pedagogical dimensions, an applied competency matrix and a structured industry– academia partnership model, is practical, scalable and immediately implementable within the Latin American university context; - Pilot implementation in mining engineering programmes at Latin American universities, preferably in partnership with active mining operations in the region, is the recommended next step, with systematic feedback mechanisms between academia and industry for continuous curriculum adjustment to evolving operational needs. In full alignment with the central theme of WMC 2026, Trust, Transformation and Technology, innovative education in rock blasting does not represent an investment in a distant future: it is an operational, strategic and competitive necessity of the immediate present. Trust is built on measurable, transparent results; Transformation demands professionals capable of thinking through the entire system; and Technology only generates value when operated by engineers with systemic vision and integrated training.
