Lubabalo Dobela, Shimlas flyhalf (with the ball), played a key role in the Shimlas’ win over Tuks in the first round of the 2018 Varsity Cup.
The Shimlas made a huge statement in their opening match of the 2018 Varsity Cup when they defeated last year’s champions at the Tuks Rugby Stadium in Pretoria.
The Free State students won the encounter against Tuks by 19-17 on Monday.
Tuks, who beat Shimlas twice last year, first in the group stage by 65-19, and then by 28-21 in the semifinals, were regarded as the hot favourites. The match was played in wet conditions which many thought would suit the home team better.
Determination carries team to win
But a young and inexperienced Shimlas team with 11 players making their debut in the competition proved that big hearts and guts count for just as much. It was only their third win in Pretoria in the 11th year of the competition and their second victory over Tuks since 2012.
As expected, both teams tightened up their approach. Shimlas struck back from a 0-5 deficit soon after the first strategy break as big and speedy wing Francois Agenbag stormed down the touchline to score a seven-point try. Flyhalf Lubabalo Dobela was on hand to convert and hand his team a 9-5 lead at the break.
Flyhalf stars in debut
The Shimlas extended their lead within five minutes of the restart as flank Benji Janse van Vuuren crashed over in the corner for a converted try. Dobela, one of the debutants who was named Player that Rocks (Player of the Match), controlled the match like a seasoned veteran. Apart from two difficult conversions from the touchline, he also slotted a penalty goal.
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.
