London-listed Gem Diamonds has recovered a 212.49 ct Type II white diamond from its 70%-owned Letšeng mine, in Lesotho. This is the sixth diamond weighing more than 100 ct to be recovered at the mine this year.

Ruthenium, one of the six platinum-group metals (PGMs), is once again being given major research attention in view of it being exceptionally suited to uplifting the efficiency and sustainability of green hydrogen production from green ammonia. Late last year, it was a ruthenium-based catalyst that augmented the scarcity of iridium, another PGM, in the production of green hydrogen from water electrolysis.

ASX-listed Lucapa Diamond Company and its Lulo alluvial mine partners Endiama and Rosas and Petalas have announced the recovery of a 195 ct Type IIa diamond from the Lulo mine, in Angola. The diamond is the sixth-largest to be recovered from the Lulo alluvial operations since mining started in 2015.

By adopting futures thinking strategies and engaging stakeholders, South Africa can better prepare its workforce for the demands of the green hydrogen economy (GHE) and transform its post-school education and training (PSET) system.

Creamer Media will host another though-provoking webinar on June 26 when a panel of experts will discuss Environmental, Social & Governance (ESG) in Mining. Panel members, including SRK consulting principal environmental scientist Wouter Jordaan and BME technology and marketing division leader Nishen Hariparsad, aim to unpack initiatives to promote ESG and sustainability in mining while also answer burning questions posed by attendees.

Nonprofit activist organisation Just Share has accused ArcelorMittal South Africa (AMSA) of sub-par AGM governance because the chairperson closed the company’s AGM on May 24 before addressing a question posed by the nonprofit. “This is surprising given the high levels of civil society engagement at its AGMs in recent years,” Just Share said on May 27, while noting that this was the first AMSA AGM it had attended.

Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.

The Presidency does not anticipate that Eskom’s move to reserve scarce grid capacity for independent power producers (IPPs) participating in public procurement bidding rounds will disrupt the more than 130 private IPP projects being advanced outside of those processes to supply private consumers. Speaking during a briefing convened to report back on the reforms implemented under Operation Vulindlela, including those undertaken to address South Africa’s loadshedding crisis, the Presid...
