Mining companies are the bedrock of the global economy, with some of the largest mining companies in the world shaping trade, investment, and development.
These organizations extract and process mineral resources that fuel everything from electronics to energy, aerospace to automobiles. Their mining operations span continents, making the sector one of the most globalized industries.
A mining company based in Australia may specialize in metal mineral resources, while another headquartered in Latin America focuses on coal or copper. Collectively, these companies in the world play a pivotal role in securing raw materials for modern life.
But, as our Global reputation report on mining, metals and minerals (MMM) sector reveals, it has its work cut out – reputationally.
The mining sector’s overall score of 66 officially ranks as Average – and it’s hardly surprising. After all, extractive industries rarely win prizes for popularity or transparency.
What’s more, our survey respondents pinpointed serious issues for mining companies to address – like the reduction of carbon emissions and of harm to people and the planet.

Trust defines leadership: The top mining companies in the world earn higher trust and reputation by combining operational excellence with transparency, safety, and measurable sustainability performance.
Sustainability drives success: From Duferco to Freeport-McMoRan, the most respected mining leaders stand out for clear ESG goals—cutting emissions, engaging communities, and reporting progress openly.
Reputation is resilience: In a high-risk, low-familiarity industry, building and tracking trust continuously gives top mining companies the credibility and protection needed to thrive amid scrutiny and change.
Many of the mining companies referenced in our recent sector report received individual Trust & Like Scores well above 66 – and many got scores well below average, of course.
One thing that unites many of these industry powerhouses is their longevity. Many of the publicly traded giants with a high Trust & Like Score were founded decades ago, indicating a long history and legacy. In addition, each company carries forward traditions of reliability, while adapting to new demands in various industries that depend on raw materials.
Several also operate significant operations across continents, with operating mines in regions that give them a significant presence in the global economy.
For many of these leaders, their diverse portfolio extends beyond metals into energy commodities, ensuring the company carries resilience against shifting market trends.
Their ability to adapt while trading stocks on major exchanges reinforces investor confidence and visibility.
By contrast, what unites many of the mining companies with lower Trust & Like Scores are fragmented operations and/or “house of brands” set-ups, both of which make the umbrella brand less recognizable in their world based markets. Of course, some also have less-than-stellar environmental records, too.
Below we take a look at which of the world’s biggest mining companies topped this year’s list. Together they’re helping shape the future of the global mining, minerals and metals sector.

What also unites many of these industry powerhouses is their apparent commitment.
Metals, materials and mining companies tend to keep a low profile – an industry-wide shyness that’s reflected in the very low Familiarity scores they get in our sector report.
But that means the survey respondents who were able to answer additional questions about the mining companies referenced in our report are more likely to be industry experts or insiders. In other words, they know what they’re talking about – making their perceptions particularly germane.
What’s especially revealing is that they pinpointed emissions reduction and harm to people and the planet as serious issues for the sector to address.
As many of the mining companies in our top 10 are taking steps to address these issues, it’s clear what other companies need to do to improve their reputation among stakeholders.

Three Chinese companies make the biggest mining companies by reputation: two steel manufacturers – Baowu and Ansteel – and Ganfeng Lithium, a major lithium mining company that plays an essential role in global energy and battery supply chains.
The other four companies are all American. They include the world’s largest gold mining company, Newmont, and Southern Copper, which produces copper and plays an essential role in supplying copper products to various mining industry markets.
National psychology and cultural norms may explain the composition of our ranking. In some countries (such as China), respondents may consider it rude to give companies low Trust & Like Scores, while in others (such as Japan), respondents may see very high scores as less credible.
Generally, too, there is greater scrutiny of business in northern European countries, resulting in lower scores, and less scrutiny in others (such as Brazil) where large companies are often viewed as more reliable than public authorities, resulting in higher scores.
Overview: As a result of several mergers, the company commonly known as Baowu is now the world’s largest steel enterprise – and entirely owned by the Chinese state. It operates as a China Ltd entity with significant influence across the mainland China steel market.
Footprint: Baowu’s headquarters are in the Baosteel Tower, in Shanghai. The company produced 132 million tons of steel in 2022 and employs over 220,000 people worldwide. Many of its projects are executed through a joint venture structure, allowing collaboration with international partners to expand technological and industrial capabilities.
Mission critical: Baowu’s stated goal is “jointly building industrial ecosphere to promote the progress of human civilization”. This mission is further strengthened by its participation in a joint venture initiative aimed at promoting sustainable practices and low-carbon innovation in the steel industry.
To that end, in 2021, it unveiled a global alliance to cut greenhouse gas emissions in mainland China. The aim of the Global Low-Carbon Metallurgical Innovation Alliance is to tackle climate change and cut emissions in the world’s biggest steel producer.
According to media reports, “the alliance hopes to advance technological cooperation and promote engineering and industrialization of low-carbon technique”.
Overview: Founded in 1916, Newmont is now the world’s largest gold mining company – and it also produces copper, silver, zinc and lead.

Equally telling are our respondents’ views on red tape. According to our survey, most people think the sector needs more regulation, not less.
Again, if we assume the respondents are particularly knowledgeable about the industry, their apparent enthusiasm for additional regulation suggests the sector may be facing a deep pool of reputational risk – and that, to mitigate that danger, self-regulation won’t cut it.
Likewise, if we assume respondents understand the reputational risks facing mining companies, we can also assume the risks would be bigger if more people knew about them.
In other words, by flying under the radar, many mining companies enjoy less visibility and less scrutiny. If that were to change – in the wake of an environmental scandal, say – some mining companies could come under the microscope like never before. For many, the problem is simple: they won’t have the protection of a robust reputation to fall back on.
As ever, the solution for the world’s biggest mining companies is to be better prepared. That means taking a more proactive approach to managing their story and using the right tools to monitor their stakeholder universe.
It also means striving to be as open and honest – and as authentic and relatable – as possible to build up the best reputational bulwark: trust.

A former editor at the Associated Press, James drives Caliber's storytelling around the fast-emerging field of stakeholder intelligence — exploring how companies can harness real-time data about the people who matter most to their success to make smarter decisions about their brand, reputation, and business strategy.
According to Caliber’s Global Reputation Rankings, the top mining companies in the world include Duferco, Swiss Steel Group, Freeport-McMoRan, China Baowu Group, and Newmont. These global leaders stand out for their strong Trust & Like Scores, commitment to sustainability, and transparent operations. They consistently perform well on ESG standards, community engagement, and responsible resource management — key drivers of reputation in the mining industry.
Mining companies can boost their reputation among younger generations by:
Emphasizing sustainability — showcasing measurable progress on carbon reduction and environmental protection.
Promoting innovation and technology — highlighting automation, renewable energy use, and digital transformation in operations.
Building a purpose-driven brand — communicating how mining supports clean energy, infrastructure, and global development.
Enhancing transparency — sharing real stories of employee safety, community impact, and inclusive workplace practices.
By aligning with values that matter to Gen Z and millennials, mining companies can present the industry as future-focused and socially responsible.
Sustainability is now a core reputation driver. Companies that demonstrate progress on emissions reduction, resource efficiency, and ethical sourcing consistently score higher in global reputation rankings. Transparent ESG reporting and measurable impact are key to stakeholder trust.
Caliber’s ranking is based on the Trust & Like Score, which measures how much stakeholders trust and like each company. The score reflects real-time perceptions gathered from thousands of respondents across markets. Companies with strong governance, clear communication, and social responsibility outperform peers in this metric.
