He founded Black Lion Property Group in 2015, a real estate development company with a portfolio of residential projects in South Africa and multi-family developments across three US states. He also serves as Group Chairman of Black Lion Mining, a subsidiary operation that has managed copper, anthracite, and diamond mining projects across Africa for approximately a decade. His career spans banking, legal services, property development, and mining. Beyond his business activities, he has funded schools for under-resourced communities, sponsored local sports programs, and maintains ongoing charitable contributions. He describes his approach to business as grounded in focus, dedication, and the ability to change with the market rather than resist it.
How do you define success?
Success, for me, has always been about happiness and the ability to enjoy what you do. I’ve watched people accumulate significant wealth and still feel hollow at the end of the day because they were chasing metrics that never meant anything to them personally. I made a decision early on that I would build businesses I was genuinely engaged with. That doesn’t make the hard days easier, but it makes the hard years sustainable.
What has been the clearest turning point in your career?
Recognizing that the systems I had built for property development were actually the answer to a problem I kept seeing in mining. Most operators in Africa treat governance as a compliance function, something you do because regulators require it. I started to understand that institutional-grade governance is actually a competitive advantage. When I brought that thinking into Black Lion Mining, the quality of decisions improved. The capacity to attract partners improved. Everything improved.
How do you make hard decisions under pressure?
I try to separate the decision from the noise. There is always noise: market commentary, competitor activity, people who want you to move faster or slower than the situation requires. The discipline is staying focused on what the actual data is telling you and what your own assessment says. Professional jealousy is a real force in business. Other people’s success can pull you off course if you let it. I don’t let it.
What has failure taught you?
Failure taught me to test my assumptions before I commit to them. In property development, you learn quickly that the gap between what you think demand looks like and what demand actually looks like can cost you significantly. I came to see that process of testing and correcting as part of the work, not as a sign that something has gone wrong.
What habits have been most important to your growth?
Reading and staying close to what is happening in global markets. Finance, politics, commodity cycles. I find that the people who get caught off guard are usually the ones who stopped looking up from their own businesses. I’ve also been disciplined about separating the urgent from the important. Most things that feel urgent are not actually important. The important things are rarely urgent in the short term.
What tradeoffs have you made?
Time. Building across multiple sectors and multiple countries means there are periods where you are stretched thin. I’ve had to be honest about what I can be present for and what I need to delegate. Delegation is not natural for people who built their businesses from scratch. Learning to trust the team, and building a team worth trusting, has been one of the longer lessons.
What does long-term thinking look like in practice?
It means making decisions that will look correct in five years even if they don’t look clever in five months. The Natal Anthracite Mine and the Kamanjab Copper Mine both required patience. The Idaho acquisition requires patience. If I were optimizing for what looks good in a quarterly review, I would make very different decisions. I’m not.
What would you tell someone starting out?
Stay focused on what you’re building. The background noise will always be there. There will always be someone who appears to be moving faster, or who appears to be in a better position. Appear is the operative word. Build something that lasts, and stay the course long enough to find out what you actually built.
