Here are the key highlights from the interview:

Q1. Brief the inception story of your organization? What inspired you to establish and follow the mission and vision of CHOC?

Inception Story


CHOC was founded in 1979 by a small group of dedicated parents whose children were undergoing cancer treatment. Faced with the overwhelming emotional, financial, and logistical challenges of navigating childhood cancer, they came together to create a support system that would ease the burden for other families. What began as a grassroots initiative has since grown into a nationally recognized organization, offering comprehensive care and advocacy for children with cancer and life-threatening blood disorders.

CHOC is a registered and internationally recognized Non-Profit Organisation (NPO), providing holistic support to children and teenagers with cancer and life-threatening blood disorders, as well as their families. Our services span the country, reaching both urban and rural communities across South Africa.

CHOC serves the childhood cancer community in South Africa; however, CHOC’s reach goes much further. We reach out to communities and serve individuals by offering a range of services. Through Childhood Cancer International, CHOC supports our sister organisations in the Sub-Saharan African countries by building capacity and sharing information.

◦ CHOC Programmes include accommodation, transport to and from treatment centres, Financial Transport Assistance, and Awareness Training and Education Programme on the Siluan Early Warning Signs of Childhood Cancer.

◦ Emotional Support (both professional and non-professional) for children, teenagers and their families through their cancer journey as well as palliative, end-of-life care and bereavement support.

◦ Patient Support for patients and families, including essential CHOC Carebags, nutritional food support, and bereavement services.

Professional Emotional Support (Psychosocial Support Services)

CHOC provides psychosocial support to children, teenagers, and their families to help them cope with the numerous new demands on the family and to provide relevant information to assist them.

CHOC employs a team of social and social auxiliary workers who provide full-time psychosocial support in the Paediatric Oncology Units, from diagnosis to the end of treatment or end-of-life care, where we also offer bereavement and grief support.

Emotional Support (Parental and Family Support)

Trained volunteers provide comprehensive emotional support to children, teenagers, and their families. We offer support groups for survivors, as well as a Parent-Supporting-Parent Programme, which provides support to parents whose children have been newly diagnosed with cancer through group discussions, and during parent tea’s at the Paediatric Oncology Units.

The psychosocial team provide support to parents and families through bereavement and grief counselling. Every year at the end of November, Remembrance Services are held nationwide. During the Remembrance Services, CHOC remembers the children and teenagers who bravely fought and sadly lost their lives. It is a chance for us to stand together with the families and doctors and pay tribute to these children and teenagers.

CHOC Education Programme

The iPad Learning Programme, facilitated by iSchool-Africa, commenced in May 2024 with CHOC Childhood Cancer Foundation SA. This initiative supports paediatric oncology patients by ensuring their education continues despite the challenges posed by cancer treatment and prolonged hospital stays. The programme brings iPads loaded with engaging content directly to children and teenagers undergoing cancer treatment. The goals include reducing anxiety, minimising learning loss, and assisting with various therapies. Comprehensive training is provided to hospital school teachers and teacher consultants to integrate the technology effectively into the children and teenagers’ routines and educational plans.

Vision & Mission

Vision: All children and teens with cancer or life-threatening blood disorders have comprehensive access to care and support.

 

Mission: Supporting children and teenagers with cancer and life-threatening blood disorders, and their families; improving early detection and augmenting effective treatment.

What This Means to Families


For the children, teenagers and families we serve, CHOC’s mission and vision translate into hope, dignity, and practical support during one of life’s most difficult journeys. The organisation stands as a lifeline ensuring that no child faces cancer alone and no parent is left without guidance.

Since transitioning from the corporate world to the nonprofit sector, I’ve found deep purpose in lending my voice to children whose own voices are often faint or unheard. CHOC’s impact supporting over 1,700 children annually, delivering thousands of bed nights, and offering psychosocial care to families nationwide, showed me the power of compassion in action. It became clear that I wanted to be part of an organization where, I can assist in reshaping the landscape of Paediatric Oncology in South Africa by empowering communities, strengthening healthcare partnerships, and ensuring that childhood cancer is met with expertise, empathy, and unwavering support.

Q2. What were some of the most significant challenges you faced during the early stages, and how did you navigate them as a leader?

When I transitioned from the corporate world into the nonprofit sector, I knew I was stepping into something far more personal and purpose-led But that shift came with its own set of challenges.

One of the first hurdles was adapting to a resource-limited environment. In corporate settings, you often have access to tools, teams, and budgets. In the non-profit world especially in healthcare, you learn to do more with less. It required a complete shift in mindset and leadership style.

Then came the emotional weight. Working with children and teenagers who have been diagnosed with cancer and their families is profoundly humbling. You’re not just managing programmes; you’re walking alongside people in their most vulnerable moments. That demands compassion, resilience, and a kind of leadership that listens more than it speaks.

Funding was, and still is, a constant challenge. Sustaining programmes such as accommodation, transport, nutritional support, and psychosocial care requires continuous advocacy, donor trust-building, and demonstrating tangible impact. However, having a strong, supportive team and board is absolutely vital to achieving CHOC’s mission. I’m deeply grateful for the collaboration, dedication, and shared vision that carry us through every challenge we face. It’s through this united effort that we continue to make a meaningful impact in the lives of children with cancer and their families.

Raising awareness in underserved communities also remains a significant challenge. Early detection saves lives, yet stigma and misinformation persist. That is why advocacy and education have become central to CHOC’s mission.

Through it all, I’ve leaned on purpose, empathy, and collaboration. I’ve worked closely with paediatric oncologists, government departments, volunteers, and donors, because leadership in this space is not about standing alone, it’s about standing together.

If I’ve learned anything, it’s this: resilience is not just about bouncing back, it’s about staying grounded in your mission even when the road gets tough. That’s what keeps me and CHOC moving forward.

Q3. In today’s rapidly evolving business world, what core values and leadership traits do you believe are most important for long-term success?

Childhood cancer advocacy isn’t just a healthcare issue; it’s a human rights issue. The next generation of African leaders must be bold enough to challenge broken systems, compassionate enough to walk with families, and visionary enough to build a future where no child is left behind.

True leadership in this space must begin with compassion. Every decision affects real lives, children determined to survive and families navigating grief and uncertainty. Compassion builds trust, and trust builds resilience.

Leaders must also be a voice for the voiceless. Across Africa, too many children and teenagers are diagnosed too late due to stigma and lack of awareness. We must influence policy, engage media, and fight for equity.

Beyond treatment, we must build systems of holistic support that empower families. At CHOC, we provide accommodation, nutritious meals, transport, and psychosocial care. These are not luxuries; they are lifelines.

Collaboration is essential. We work hand-in-hand with paediatric oncologists, nurses, social workers, government, and NGOs. Our partnerships with SAPHO and the Tumour Registry are examples of how collective effort creates systemic change.

Finally, leaders must remain resilient and purpose driven. The work is tough, funding is limited, and the emotional toll is heavy. But the mission is too important to abandon. At CHOC, we stay focused on the children, we adapt, we grow, and we keep showing up.

To the next generation of leaders: lead with heart, build with vision, and never forget who you’re doing it for.

Q4. In your opinion, what are the key qualities required for a successful leader in today’s business environment?

Leadership, particularly in the non-profit healthcare sector, is impossible without a strong and passionate team. At CHOC Childhood Cancer Foundation SA, our regional teams, social workers, and volunteers, work near paediatric oncology units across the country, ensuring that families receive consistent, practical, and emotional support during the most challenging times of their lives.

This frontline presence is backed by a robust finance and governance framework, along with a dedicated HR function that empowers staff to focus on what matters most while supporting children, teenagers and their families. With systems in place to ensure compliance, transparency, and operational efficiency, our teams can channel their energy into care, advocacy, and impact.

Strong fundraising programmes, driven by empathy and strategic execution, allow CHOC to sustain and grow its services. Our staff and volunteers gain immense personal and professional fulfilment from the work they do, witnessing the resilience of adolescents, the gratitude of families, and the tangible difference their efforts make in the lives of others. This work cultivates a deep sense of purpose, compassion, and unity across the organisation.

At the heart of this cohesive and mission-driven culture as the CEO, my leadership brings together diverse teams under a shared vision of excellence, compassion, and accountability. I ensure that every part of CHOC from governance and fundraising to frontline support is aligned and working collaboratively. My ability to inspire, connect, and lead with integrity has been instrumental in building a united organisation where every team member feels valued, supported, and driven by the cause.

Together, CHOC’s people form a powerful force for good, one that not only uplifts children and teenagers with cancer and their families but also strengthens the broader healthcare and non-profit landscape in South Africa.

Building on this foundation, I believe the following leadership qualities are essential:

  • Authenticity: Great leaders are grounded in who they are, lead with integrity, and are not afraid to show vulnerability.
  • Empathy and compassion: Emotional intelligence is non-negotiable. Understanding your team and community builds trust and resilience.
  • Visionary thinking: Leaders must inspire others toward a better future, anticipating change and embracing innovation.
  • Adaptability: The world is fast-changing. Leaders must be agile, open to feedback, and committed to lifelong learning.
  • Collaboration and influence: Leadership today is about building coalitions and empowering others, not controlling them.
  • Resilience: Setbacks will come, but true leaders remain steady, model perseverance, and inspire others to do the same.
  • Strategic communication: Clear, transparent, and inspiring communication aligns people with purpose and drives culture and impact.

Q5. What advice would you offer to the next generation of entrepreneurs and leaders across Africa?

My advice is simple but profound: lead with empathy. In our field, compassion isn’t a luxury, it’s a necessity. Every child we serve is more than a diagnosis; every caregiver is more than a support system. They are the heartbeat of our mission.

Build systems that wrap around the family holistically – medically, emotionally, logistically, and socially. At CHOC, we’ve seen how something as simple as a warm bed, a meal, a transport voucher, or a listening ear can transform a family’s experience.

Embrace innovation from data-driven treatment plans to mobile health tools but ensure that technology serves humanity and reaches even the most remote communities.

Above all, embrace collaboration. At CHOC Childhood Cancer Foundation SA, partnership is not just a strategy, it’s a lifeline. We actively engage with a wide network of stakeholders including government departments, public and private hospitals, NGOs, corporates, and community organisations. These relationships are foundational to our mission of supporting children with cancer and their families. These alliances are deeply meaningful. They reflect a shared commitment to dignity, hope, and healing. Every stakeholder plays a role in the journey of a child or teenager who has been diagnosed with cancer, and CHOC is proud to be the thread that weaves these efforts together

To young African leaders: be bold, be kind, and be relentless. The children of this continent deserve nothing less.

I’ve had the privilege of surrounding myself with an exceptional team, and I truly believe I work alongside some of the most dedicated and compassionate individuals. Together, we are not just colleagues—we are a united force making a meaningful difference in the lives of children with cancer. I’m deeply honoured to work with people who bring heart, purpose, and unwavering commitment to everything they do.

Q6. What do you see as the most impactful trends or transformations shaping your industry in 2025 and beyond?

The childhood cancer field is undergoing profound transformation, driven by innovation, collaboration, and equity.

We are at a turning point. In high-income countries, survival rates for childhood cancer exceed 80%, while in many parts of Africa, survival is just 20%. This disparity is unacceptable—it is a call to action.

Global initiatives such as the WHO Global Initiative for Childhood Cancer (CureAll framework) are working to raise survival rates to 60% by 2030. For CHOC, this means deepening our involvement in public health, advocacy, and grassroots awareness.

Families affected by childhood cancer face immense psychological, emotional, financial, and logistical challenges. Many experiences strain due to travel distances to treatment centres, lack of nearby accommodation, out-of-pocket expenses, and disruptions to family life. The burden is shared not only by patients, but also by parents, siblings, and caregivers. As reflected in the global campaign #WeAllLiveIt, when a child is diagnosed with cancer, the entire family embarks on the journey together. But medicine alone is not enough. Healing requires wraparound support, beds near hospitals, nutritious meals, transport assistance, and psychosocial care. CHOC’s integrated model is designed to provide this, and it is increasingly being recognised as best practice worldwide.

Collaboration is another key driver. Governments, NGOs, hospitals, and the private sector are working together like never before. CHOC’s partnerships help shape national policy and strengthen healthcare systems from the ground up. The Department of Health, NCR, CHOC, SAAPHO, and WHO commend the dedication of healthcare professionals, support organisations, and members of the public who offer vital care and compassion to children with cancer. The NCR remains committed to ensuring accurate data collection and analysis to inform decision-making and improve outcomes.

Finally, the voices of survivors are reshaping the conversation. Their stories guide how we design programmes and ensure long-term healing.

The future of childhood cancer care will be more connected, compassionate, and equitable and CHOC is determined to help lead that transformation.

Q7. Brief us about your future roadmap.

Our future roadmap is focused on both strengthening and innovating:

  • Enhancing existing programmes to further reduce treatment abandonment rates.
  • Expanding awareness campaigns, across South Africa, ensuring no environment is overlooked, to educate communities on the early warning signs of childhood cancer.
  • Innovating support models, leveraging digital tools, expanding accommodation and nutritional programmes, and strengthening psychosocial services.
  • Building stronger collaborations with government, hospitals, and NGOs to unify efforts under paediatric oncology units.
  • Empowering survivors and families to share their voices, guiding us in creating more relevant and compassionate programmes.

Our vision for the future is clear: a South Africa where no child faces cancer alone, where early detection is the norm, and where every family receives the support they need to stay strong and hopeful.

Automation to Intelligence: The Next Frontier of Mining Technology

The mining industry, which used to be all about heavy machinery and hard manual work, is now undergoing a major transformation thanks to artificial intelligence (AI). With the global appetite for minerals and metals on the rise, mining companies are increasingly turning to AI to boost efficiency, enhance safety, and promote sustainability at every stage of their operations. From the initial exploration to extraction and processing, AI is changing the way we discover, develop, and deliver these vital resources.

One of the most impactful ways AI is transforming the mining industry is through exploration and resource discovery. Traditionally, exploration has been a lengthy and expensive process, often requiring extensive surveys and drilling. However, with the help of AI-driven data analytics, companies can now sift through massive geological datasets to spot potential mineral deposits with much greater precision. Machine learning algorithms can analyze satellite images, seismic data, and geochemical trends to identify the area’s most likely to yield success, ultimately cutting down on exploration costs and minimizing environmental impact.

Once operations kick off, AI takes center stage in fine-tuning extraction and production processes. With smart sensors and autonomous equipment driven by AI, machinery performance and site conditions are monitored in real time. These advanced systems can foresee equipment failures before they occur, helping to cut down on downtime and maintenance expenses. We are seeing more autonomous haul trucks and drilling rigs in action, working with impressive precision, and reducing the need for humans to be in risky areas.

AI is revolutionizing safety management, which is a top concern in the mining industry. With the help of intelligent monitoring systems that leverage computer vision and predictive analytics, potential safety hazards can be identified ranging from structural weaknesses to unsafe behaviors among workers. These early-warning systems empower companies to act quickly, helping to prevent accidents and prioritize the well-being of their employees.

In the world of processing and refining, AI is a game changer for boosting efficiency and sustainability. It does this by fine-tuning energy consumption, managing waste, and streamlining chemical processes. With the help of machine learning models, companies can analyze ore grades and automatically tweak processing parameters, which not only enhances yield but also minimizes environmental impact. Plus, AI-powered systems for managing water and energy are essential for helping businesses achieve their sustainability targets and stay in line with environmental regulations.

AI is not just about making things run smoothly; it also plays a crucial role in helping leaders make smart decisions by transforming data into practical insights. By pulling together information from every part of the value chain, executives can confidently tackle decisions related to production planning, logistics, and market forecasting.

While there are still hurdles to overcome, like the hefty costs of implementation and the challenges of data integration, the potential of AI in mining is truly remarkable. The future of the mining industry will be shaped not just by automation, but by smart technology that learns, adapts, and collaborates with humans to create a safer, more intelligent, and sustainable environment.

Oscar van Antwerpen: Leading Africa’s Mining Future with Integrity, Innovation, and Impact

In the world of mining and natural resources, where geology meets engineering and strategy intertwines with sustainability, Oscar van Antwerpen has been functioning and interweaving these disciplines to carve a distinctive path. His journey is not merely about extracting value from the Earth, but about unlocking potential of people and processes, and the planet itself. From his early fascination with geological formations to his leadership in reshaping Africa’s mining narrative, van Antwerpen’s career reflects a blend of scientific curiosity, ethical conviction, and visionary leadership.

A Curiosity Born from the Earth

For Oscar, the fascination with the natural world began long before he entered the mining industry. As a child, he was fascinated by the patterns of rocks exposed in road cuttings, the layers of mountain formations, and the stories told by fossils. Initially drawn to botany and zoology, his academic curiosity took a new direction when he stumbled upon the geology department’s mineral collection. That moment, as he describes it, was transformative: “It completely shifted my perspective.”

The mineral collection portrayed the beauty of Earth’s processes, the chemical precision, the geological mystery, and the tangible link between science and the real world. Geology became a tool to understanding not just how the Earth worked, but how humans could interact with it responsibly. That fascination developed into a lifelong interests and study combining natural science with the practical applications of engineering. Mining, for him, became the ultimate field where those worlds met.

Standing 3,000 metres below the Earth’s surface for the first time, surrounded by the product of millions of years of geological transformationan orebody —van Antwerpen recalls being filled by amazement. “It was a showpiece  of engineering,” he says. “Mining gave me the opportunity to solve complex challenges across different disciplines, every project a new problem to understand, every orebody a new set of rules to understand.”

A Leadership Vision Rooted in Empathy and Excellence

Van Antwerpen’s leadership philosophy is grounded in a simple belief: people thrive when they feel valued, acknowledged, and empowered, and participating in a project and or company with direction.   “Great leadership,” he says, “starts with recognising the value of diverse talent—intellectual, emotional, and creative.”

Oscar leads with empathy, creating environments where his teams feel supported to grow, contribute meaningfully, and pursue their personal goals. His approach is far from traditional; it combines technical excellence with emotional intelligence. Under his guidance, teams are encouraged not only to meet operational targets delivering projects safely, sustainably, on time, and within budget but also to innovate, challenge conventions, and think differently.

Van Antwerpen’s mission is clear: to lead by example, build shared purpose, and deliver sustainable impact. It is a style of leadership that has inspired loyalty, driving performance across the mining sector. 

Navigating Challenges with Integrity

The mining sector in Africa, despite its vast potential, faces numerous challenges from corruption, starvation, famine, war to mineral tenement problems, logistical constrains, skill shortages and electricity shortages. For van Antwerpen corruption stands as one of the greatest barriers to progress. “Corruption doesn’t just slow things down,” he notes. “It undermines development, diverts funds, and damages trust.” It also undermines investor interest.

Encouragingly, Antwerpen sees positive change. “In countries where corruption is being tackled head-on, progress is tangible. Ethical leadership is not optional.  It is the key to transforming resource wealth into sustainable development.” His conviction that integrity is the foundation for long-term growth has become a cornerstone of his leadership legacy.

Redefining Mining through Geometallurgy

Among van Antwerpen’s most transformative achievements is his application of geometallurgy, an approach that integrates geological and metallurgical insights to optimise mining operations. Traditionally seen as a technical specialty, geometallurgy has become a central tool in day-to-day operations, revolutionising resource extraction and recovery.

The results have shown that projects once deemed non-viable are now profitable, resources previously out of reach are being successfully mined, and efficiency has improved across multiple sites. The use of this technique has helped many marginalised ore deposits to be mined profitably.  .

Sustainability at the Core

Van Antwerpen’s approach to mine planning and resource optimisation is  intertwined with sustainability and community empowerment. “Sustainability isn’t an add-on.  It’s built into how we operate from day one,” he emphasises. His focus extends beyond compliance to real, lasting impact.

Oscar, also champions geometrical modelling, integrating geological and metallurgical data to refine mine plans and optimize production. The result? Lower capital costs, higher project value, and improved IRR and NPV. “Innovation isn’t about replacing people,” he explains, “it’s about empowering them to work smarter, safer, and more effectively.”

Oscar strongly advocates for in-country beneficiation, ensuring that raw materials are processed locally to stimulate job creation and strengthen local economies. “It’s about keeping value where it’s needed most,” he says. Environmental rehabilitation is another priority. From land restoration to preventing acid mine drainage, his teams work diligently to ensure these considerations are integrated to the planning process.  .

On the human side, van Antwerpen’s philosophy is clear: communities must grow alongside the mines. His organisations invest in structured training, career development, and the integration of local talent into core operations. “We want to build something that lasts,” he adds. “That’s the true spirit of sustainable development.”

Harnessing Innovation and Technology

Technology, for van Antwerpen, is more than a tool: it’s a mindset. His company has been developing in-house tools to leverage AI and deep learning in geological exploration and modelling, enhancing the process of target selection.  These systems have dramatically improved the detection of geological anomalies as the datasets currently being generated are fast and complex. 

Empowering Local Talent and Building Capacity

Central to van Antwerpen’s leadership is a deep commitment to local empowerment. He prioritises hiring and training local geologists and engineers, fostering skills transfer and capacity building across the continent. “We invest in education and training because that’s what makes development sustainable,” he says.

Through partnerships with universities and graduate programs, his teams are nurturing the next generation of mining professionals. It is a long-term strategy designed not only to grow talent but also to anchor expertise within Africa. “We’re building the future workforce of the industry,” he notes.

Africa’s Place in the Global Mining Economy

Africa, van Antwerpen believes, stands on the brink of a major transformation. With vast reserves of critical minerals— from copper and iron ore to rare earths—the continent has all the ingredients for a thriving mining economy. But, as he points out, “having resources isn’t enough.”

Oscar’s focus has been on promoting internal processing, strategic planning, and transparency to ensure that Africa captures more of the value chain. He also places strong emphasis on education, empowering leaders and decision-makers to understand the transformative power of geometallurgy—and to ensure resource rent is put to proper use.

“It’s a mindset shift,” he says. “Africa is not just a source of raw materials. It is a global player with the expertise, technology, and leadership to shape its own destiny, and should be developed as such.”

Looking Ahead: A Smarter, More Sustainable Future

In the short term, van Antwerpen’s goals are focused on expanding the implementation of geometallurgy and improving resource extractability. In the long run, he envisions an African mining industry that is self-sufficient, technologically advanced, and globally competitive.

That vision includes stronger local beneficiation, deeper environmental stewardship, and genuine community engagement. “Success,” he says, “isn’t just measured in tonnes mined or profits made. It’s measured in the value we create for people, for the environment, and for the future.”

A Legacy of Empathy, Integrity, and Empowerment

Asked what advice he would give to aspiring leaders, van Antwerpen does not hesitate. “Leadership starts with empathy, integrity, and purpose. Education, transparency, and strategy must sit at the centre of everything we do.”

Oscar urges young leaders to tackle corruption, to innovate fearlessly, and to build organisations that uplift rather than exploit. “Real change doesn’t happen by accident; it happens when leaders act with integrity and vision.”

Among his proudest initiatives is the “Be The Good” foundation,  his non-profit dedicated to supporting vulnerable communities through early childhood development and poverty relief programs. It reflects the same principles that guide his professional life: empathy, education, and empowerment.

And perhaps that is the essence of Oscar van Antwerpen’s story: a leader who looks beneath the surface not just to extract value, but to uncover meaning; who sees mining not as an end, but as a platform for progress. His legacy is not only in the resources unearthed from the ground, but in the opportunities and hope he helps cultivate above it.
