Influential Women in Mining: Denise Johnson’s Story

Mining has historically been one of the most male-dominated industries in the world. From underground operations to executive boardrooms, the presence of women has often been slim. Women have often been excluded from operational, leadership and decision-making roles, both by cultural norms and systemic barriers.

Despite the gender imbalance among mining workers, women have continuously made grand strides within the industry, resulting in pivotal changes. One leader at the forefront of that progress is Denise Johnson, whose career has redefined what leadership looks like in mining.

As Group President of Resource Industries at Caterpillar, she is not only driving advances in sustainability and technology but also challenging outdated norms about who belongs in leadership. Johnson’s rise from mechanical engineer to one of the highest-ranking executives in mining underscores the critical role that diversity and equity play in fostering innovation—and serves as a visible reminder to the next generation that the industry’s future must be built by a broader range of voices.

Johnson’s Stride to Success

Johnson’s path into engineering and mining was anything but linear. Though now recognized as one of the industry’s most influential leaders, her beginnings were rooted in curiosity and a deep passion for learning. She recalls that it was her early interests in problem-solving and technical subjects that first set her on this course.

“I started with a passion for problem‑solving and a love for math and science,” she said.

That foundation led to a mechanical engineering degree and dual master’s credentials in mechanical engineering and business. Afterwards, she spent the early part of her career at General Motors, where she gained rich experience in manufacturing and product management, laying the groundwork for her next big move.

Her entry into Caterpillar in 2011 marked the turning point that would launch her into the mining sector. Starting as General Manager of the Specialty Products business unit, she quickly proved her ability to lead complex divisions. Six years later, she was promoted to Group President of Resource Industries, where she now oversees some of Caterpillar’s most impactful areas, from operations to mining technology.

“What drew me to Caterpillar was its global impact and the opportunity to work on meaningful, large‑scale challenges in industries like mining that are essential to help the world grow,” she said.

Johnson acknowledges that female leadership was especially rare when she began her career. Yet she was fortunate to have both male and female mentors who believed in her potential and encouraged her to stretch into new roles. She emphasizes the power of seeing others break barriers as a source of inspiration for her own path.

“I’ve also been inspired by trailblazers in STEM who broke barriers and paved the way for others,” she said.

Among those she admires is Kathleen Quirk at Freeport-McMoRan, someone Johnson says is making meaningful change in the industry. “It has been fun to work alongside her… and I’m thrilled to see she’ll be inducted into the American Mining Hall of Fame. This type of recognition lifts up the entire mining industry.”

Even with her rapid rise, Johnson insists that ambition alone was never the driving force behind her career. Instead, she has always chosen to focus on the work at hand and let results speak for themselves. By leaning into challenging assignments, she discovered that the toughest environments often provided the most growth.

While she didn’t foresee rising so quickly through the ranks at Caterpillar, Johnson has always focused on doing the job in front of her to the best of her ability. “I’ve always been driven by impact, not position,” said Johnson. That mindset led her to take on tough roles others passed up—what she calls “prickly situations”—and it was in those spaces that she found the most growth.

Like many other industry workers, Johnson recalls moments when she had to prove herself more than others. She notes that confidence isn’t something you simply inherit—it is something built steadily through experience, setbacks and the right support network.

“Confidence comes from preparation, experience, and surrounding yourself with people who challenge and yet support you,” she said. “Resilience is built over time—through new experiences and setbacks, through failures, and through staying true to your values.”

Today, Johnson sees her role as extending beyond corporate leadership. She views her presence as an opportunity to shift perceptions about what leadership looks like in mining. Her visibility as a woman at the top of a global company demonstrates that representation matters, and she hopes it motivates others to pursue careers in industries where women have historically been underrepresented.

“It’s an honor and a responsibility. I’m proud to represent progress in an evolving industry,” said Johnson. “When women see other women in senior leadership positions, it helps normalize it.”

She also believes that creating a sense of belonging is as important as achieving personal success. By showing others what’s possible, she hopes her own journey will encourage women to aim higher and push past limiting expectations.

Offering a piece of advice to women entering the field, Johnson’s message is clear. “Your perspective is valuable, and the industry needs diverse voices to innovate and grow,” she said. “Be curious, be bold and seek out mentors. Most importantly, believe in your own ability to lead and make a difference. Act confident, even if you don’t feel it yet.”

Looking ahead, Johnson stresses the importance of the mining industry’s ability to attract and retain more women. One way to strengthen this outcome is through the connection between career purpose and growth. She believes that when people understand mining’s essential role in society, it becomes easier to see why diverse perspectives are critical to its future.

“Mining is essential to modern life—it provides the raw materials needed for everything from infrastructure and energy to electronics and healthcare,” she said. “The challenges facing mining today—safety, sustainability, innovation, workforce development—require a wide range of perspectives and skills.”

Understanding the importance of mining in society is key, and attracting all individuals to the industry is crucial. Johnson’s story is a compelling example of what’s possible when talent, determination and purpose align. Her journey underscores the vital role women can play in shaping the future of mining—not just as participants, but as decision-makers and innovators. As the industry continues to evolve, voices like hers will be key to ensuring it becomes more inclusive, more forward-looking and better prepared to meet the challenges of a rapidly changing world.
