The Geological Society of South Africa (GSSA) names Joshua van Blerk (27) as the 2025 recipient of the Corstorphine Medal. One medal is awarded annually, in recognition of an exceptional MSc dissertation in the geological sciences. Josh's MSc dissertation was on the oxygen isotope geochemistry of megacrysts (large crystals of minerals such as olivine, pyroxene and garnet) from the Monastery kimberlite in the Free State.

Mr van Blerk is overjoyed, although his first reaction was disbelief, "my instant reaction was that it must be a mistake", he said. Like many students who have done an MSc, Josh also had his fair share of challenges, including the fear of failure and wondering if he had the mental capacity to push through. He recalls that, on some days after reading research papers endlessly, writing one sentence was a very big accomplishment. Josh feels that this recognition affirms that he belongs in geological sciences and that he is smart enough to be here. 

Behind any win is a community of individuals that have walked the journey with them, whether throughout the whole process or only for a little while. Josh expressed his gratitude to his academic supervisors (Dr. Geoffrey Howarth, Professor Chris Harris and Professor Philip Janney), who were always willing to assist and gave useful insights pertaining lab work and writing. Josh is most thankful to his family, friends and boyfriend for their love and support they gave him throughout his MSc journey. "Finally, I would like to give a special thanks to my parents for always being present and caring for my needs and for giving me the opportunity to have a tertiary education", said van Blerk.

When asked for words of encouragement to anyone trying to finish their degree, Joshua said this:

"It’s cliché, but NEVER GIVE UP! There will inevitably be nights where you feel like you may never figure out a specific problem, but speaking from experience, what worked for me was just powering through it all. Don’t stop researching papers for your one answer, don’t be afraid of “sounding stupid” when you want to ask a question, don’t think that all your hard work will go unrecognised, and never ever think that you’re not good enough, because if you put your mind to it, you can accomplish anything!"

At the present moment, Joshua is working as a Scientific Officer in the MC-ICP-MS facility housed in the Geological Sciences department. "While my appetite for knowledge is still full, I’d like a little break from research!", when asked about his future plans.  

The Geological Sciences Department is truly proud of Joshua's achiecement!
