Jaco Peyper, former Kovsie, will handle a quarter-final match at the Rugby World Cup. It will also be his 50th test match.

With the appointment of Jaco Peyper as referee there will be Kovsie alumni among the referees, players and coaches in the quarter-finals of the 2019 Rugby World Cup in Japan on 20 October.

Lappies Labuschagné will start on the flank for Japan in their clash against the Springboks on Sunday. Labuschagné, a former Shimla captain, is second on the list for tackles made in the tournament thus far.
In the Springbok camp there are former University of the Free State (UFS) students in Rassie Erasmus (head coach) and Jacques Nienaber (defence coach).

UFS alumnus Jaco Peyper has been entrusted with the whistle in Sunday’s other quarter-final between Wales and France. It will be a memorable match for Peyper as it will be his 50th test appearance as the 31st man on the field – making him only the third South African to achieve this feat.

Peyper, who is the only South African among the 12 referees at the tournament, made his World Cup debut in 2015 when he officiated the opening match. In total he has handled six World Cup encounters. 

His illustrious career has seen him become only the fourth referee in history to officiate in 100 Super Rugby matches earlier in the year, in which he also handled the final (his fourth Super Rugby final). Peyper scooped the SA Referee of the Year award in 2018 for a third time, a year in which he took charge of his fourth Currie Cup Final.

“The fact that he is only the third South African referee to take charge of 50 tests indicates what a special achievement this is. It takes years of hard work and dedication to reach this level as a referee, and to maintain this standard year-in and year-out is even more challenging as it requires one to produce effective performances consistently,” said Jurie Roux, the CEO of SA Rugby.

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.
