The Kovsie Annerie Dercksen is one of South Africa’s most promising youngsters and climbing the cricketing ladder.
She enjoyed every second of playing with some of her heroes and believes the exposure to international cricket will help her become a better player.

Star from Beaufort West
This second-year Education student from the University of the Free State (UFS), who dreams of playing for the Momentum Proteas, represented the South African Emerging Women’s team three times in 2021.
The star from Beaufort West toured with the side to Bangladesh and also played against Zimbabwe and Thailand in One Day and T20 matches.
According to Dercksen, it is an incredible honour and privilege to be a part of a side.
She soaked up the experience and says everyone was willing to share their knowledge.
“I would have to say, sharing the field with some of my heroes and getting to work with some of the best coaches in the country are some of the highlights.”
She says each tour brought its own challenges and this helped her grow in the way she views and approaches the game.
“In Bangladesh we played against a well-established team in foreign conditions while facing a lot of spinners in spin friendly conditions. Personally, it was quite a challenge and I had to come back and work on some options, especially against spin.”

Coming through the ranks
The all-rounder has come through the ranks. She represented South-Western Districts at school level, played for the South African U19 side and is currently representing the Free State.
But Dercksen didn’t always dream cricket, especially not when playing ‘backyard’ cricket with her brother on the farm.
She didn’t even play for a team at school. “Until a boy from our primary school’s team got sick before a game. A teacher came to class and asked, ‘who can play cricket’, and I put up my hand.”
Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.
The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.
This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.
Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.
The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.
For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.
“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”
Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
