Global mining companies recorded 42 worker fatalities in 2024, the International Council on Mining and Metals revealed on 14 December, marking a second consecutive annual increase and underscoring the persistent hazards of underground operations worldwide. The industry group’s latest safety performance data documents fatalities rising from 36 in 2023 and 33 in 2022, reversing earlier progress and challenging corporate pledges to drive incidents to zero.
The confidential but aggregated statistics are drawn from ICMM’s 25 member companies that operate more than 1,000 sites on six continents. Nearly half of the deaths—43 percent—occurred below ground, accentuating the particular dangers of extracting ore in confined, pressurised and often remote environments. The headline numbers and supporting analysis appear in ICMM’s summary news release as well as its 36-page safety data compendium, both issued from London on Thursday (ICMM release).
The full report, available as a downloadable PDF, drills into regional, operational and causal trends, highlighting how underground environments remain prone to rock-falls, ground instability and vehicle collisions despite improvements in monitoring technology (benchmarking study).
ICMM’s chief executive, Rohitesh Dhawan, wrote in an accompanying statement that “every fatality is a tragedy that should not happen,” pledging continued collaboration among members to learn from each occurrence. He acknowledged, however, that 2024’s reversal “shows we are not yet consistently eliminating the most serious risks,” particularly those inherent in deep or geotechnically complex mines.
Rising dangers below ground
Of the 42 deaths, 18 occurred in underground operations. Analysts inside ICMM attribute the disproportionate toll to older mine infrastructure, the physical complexity of navigating shafts and tunnels, and the challenge of managing heavy mobile equipment in confined spaces. Surface mines reported the remaining fatalities, with “worker interaction with vehicles and mobile equipment” cited as the single most frequent cause across all environments.
The report’s authors caution against viewing the aggregated data as a comprehensive global census—ICMM members represent roughly one-third of the world’s industrial mining output—but note that their operations span gold, copper, iron ore and bulk commodities in both developed jurisdictions and high-risk frontier markets. The annual exercise offers rare insight into how the largest operators are faring against their own “zero harm” targets.
Why the business case for safety is growing
The rise in fatalities carries financial ramifications. According to the 2025 EY Global EHS Maturity Study, 70 percent of Canadian mining executives say safety initiatives have a direct, measurable impact on business performance, while 85 percent link comprehensive environmental, health and safety (EHS) programs to operational efficiency gains. Investor scrutiny of safety metrics has intensified, with asset managers flagging poor records as indicators of broader governance weaknesses.
“Safety incidents are a leading indicator of operational risk,” notes one Toronto-based institutional analyst who tracks listed majors. “If a company cannot manage the known hazards of underground mining, stakeholders worry about how it will manage the more complex ESG expectations now being priced into valuations.”
Leadership and culture over technology alone
ICMM’s benchmarking exercise emphasises that eliminating fatalities depends on organisational behaviour as much as on equipment. The council urges executives to model safety-first attitudes—visiting worksites, engaging crews, and empowering frontline employees to pause work when conditions change. It also recommends cross-company sharing of root-cause investigations so that lessons migrate quickly throughout the membership.
Recent case studies cited in the report detail how some miners are embedding “critical control management” frameworks, mapping the barriers that must remain intact to prevent catastrophic events. Where those controls fail—often through over-familiarity or production pressure—the likelihood of fatality spikes dramatically.
Technology plays a pivotal role. Advanced proximity-detection systems, real-time geotechnical monitoring and automated equipment can all reduce human exposure. Yet adoption remains patchy, particularly among mid-tier operators and in aging underground complexes where retrofitting sensors or autonomous fleets is cost-intensive. The council argues that leadership must view such investments not as discretionary add-ons but as central to licence-to-operate credentials.
Anatomy of three major risk areas
Within the 2024 dataset, ICMM identifies three recurring themes:
• Vehicle-related incidents: Mobile equipment caused 12 deaths, half occurring when operators or spotters lost line of sight in low-visibility drifts. The report calls for wider deployment of collision-avoidance radar and mandatory reverse-parking protocols.
• Rock-falls and ground failure: Nine fatalities stemmed from ground-control failures. Although seismic monitoring has improved, the report notes that pre-conditioning and reinforcement methods lag behind best practice at some narrow-vein mines.
• Falling objects and entanglement: Seven deaths were linked to suspended loads or rotating machinery, suggesting lapses in lock-out/tag-out procedures.
Each category points to established controls that are well documented but unevenly applied. ICMM urges members to audit the effectiveness—not merely the existence—of their critical controls and to integrate leading indicators into board-level dashboards.
Hard numbers hide individual stories
Because the dataset is aggregated, individual incident narratives are anonymised, but incident descriptors convey the gravity of underground hazards: an underground locomotive striking a night-shift electrician; a rock-burst collapsing a stope while two chargemen prepared explosives; a maintenance fitter caught in an unguarded conveyor tail-pulley. Each represents a tragedy that ripples through families and remote communities where mines are often the primary employer.
Progress is not linear
ICMM’s own history shows that progress can stall. From 2012 to 2020, member fatalities were nearly halved, driven by concerted campaigns on fatal-risk protocols and group leading-practice exchanges. The last two years remind executives that gains are reversible, particularly as operations push deeper underground chasing higher-grade ore while the sector simultaneously contends with labour shortages and aging workforces.
Comparison with other high-risk industries is sobering. Commercial aviation has achieved a fatality rate near zero through standardised reporting, independent investigation bodies, and mandatory fleet upgrades. Mining lacks a global regulator with similar enforcement capacity, relying on national inspectorates of varying capability.
Industry reaction
Several major producers issued statements following ICMM’s release, reiterating zero-harm commitments. BHP, Anglo American and Rio Tinto—each ICMM members—did not disclose site-specific numbers but said they would review the council’s findings against internal risk registers. Labour unions renewed calls for stronger whistle-blower protections, arguing that production bonuses can still compromise safety decisions in underground stopes and haulage ways.
Regulators in Canada, South Africa and Chile said they would study the global dataset to benchmark domestic performance. Chile’s National Geology and Mining Service (SERNAGEOMIN) told local media it plans to align upcoming guidance on underground haulage with the collision-avoidance recommendations in the ICMM report.
Path forward: integration, not isolation
Experts interviewed for this article emphasise that future improvement depends on integrating technology, culture and governance. Real-time data analytics can flag deviations before they become disasters, but success requires frontline workers to trust and act on those alerts. Boardrooms must allocate capital not just to ore-body access but to redundancy in critical controls. Cross-jurisdictional learning must outpace mine-site custom—”how we do things here”—that often resists outside lessons.
The confluence of escalating underground risk and intensifying ESG scrutiny means safety performance is increasingly material to balance sheets. Insurance premiums for deep-level operations have risen, reflecting underwriters’ concern over seismic risk and mobile-equipment collisions. Simultaneously, investors integrating sustainability metrics are discounting companies that cannot demonstrate year-on-year reductions in serious incidents. Safety is becoming a competitive differentiator akin to ore grade or cost curve position.
Leading firms now pilot automated drilling rigs and battery-electric haul trucks to reduce diesel particulates and eliminate operator exposure. Yet technology is not a panacea; cultural reinforcement is vital. Behaviour-based programs that rely solely on worker vigilance have shown diminishing returns, whereas systems that track leading indicators—control verifications, near-miss trends—allow proactive intervention.
What success looks like, practitioners say, is not a single metric but a resilient system: one in which controls are verified daily, critical deviations trigger automatic stoppages, and information flows freely between mines—even among competitors—because the cost of secrecy is measured in lives.
With 2024’s sobering numbers now public, the mining sector faces a familiar but urgent challenge: embed lessons faster than operations evolve. Anything less risks repeating the same statistics in next year’s report and eroding the industry’s social licence at a moment when it must supply the minerals driving the energy transition.
