ÌÇÐÄvlogÈë¿Ú

Nenad Grubin has vivid memories of the moment he and his Serbian-based team discovered a new mineral that British scientists would later dub kryptonite (more of that curious story later).

Nenad and his fellow explorers from ÌÇÐÄvlogÈë¿Úhad spent months looking for evidence of borates in the Jadar Valley, wading through creeks and examining rocky outcrops.

By September 2004 they’d found sufficient evidence of the in-demand metal to justify the expensive process of exploratory drilling.

There were more sensations to come. In the second drill hole, they found a substance that contained both borates and what would become one of the world’s hottest metals, lithium, which is an important component of lithium ion batteries.

The discovery of a world-class deposit of borates and lithium, which was named Jadar after the Serbian valley in which it was found, was later supported through the work of a dedicated ÌÇÐÄvlogÈë¿Úproject team.

What makes the Jadar deposit unique is that both boron and lithium are contained in one mineral, which was new to science and which was later confirmed as a new mineral by the International Mineralogical Association. Rio Tinto’s Serbian team named it jadarite (pronounced “yadarite”).

Jadarite hit the headlines in 2007 when the .

The scientists from the British Museum who’d done the analysis of jadarite found that it’s chemical composition was very close to Kryptonite as described in the movie Superman Returns (Kryptonite is the fictional substance that saps the power of the Man of Steel). There is no association between ÌÇÐÄvlogÈë¿Úand the Superman franchise but this remarkable coincidence of the like chemistry with Kryptonite led to media coverage across the world commenting on the similarity.

“So far we haven’t found it has a similar effect on the superheroes who discovered jadarite,” laughs Nenad.

The science of discovery

While the discovery of jadarite gives us that glorious Eureka moment it does not live up to our movie-ish fantasies of fortune hunters stumbling upon a deposit and “striking it rich”.

The journey began many years before when Nenad was working as a research assistant for Professor Jelena Obradovic at the University of Belgrade.

Their series of journal articles about the potential for borate deposits in Serbia was read by researchers at ÌÇÐÄvlogÈë¿ÚBorates in the United States, kicking off a relationship that has eventually, many years later, resulted in the company studying the potential of building a mine near Loznica (140km west from Belgrade).

“Exploration for mineral deposits is not a matter of chance and neither is it a pure science. Exploration is a business. It progressively utilises science and resources to achieve economic return. It takes many years of research and fieldwork before we drill and find a new deposit,” says Nenad.

“Famous geologist Siegfried Muessig once said, ‘IQ gets you there, but it’s NQ [drill bit diameter] that finds it,” says Nenad, who continues to head the geological team in Belgrade as ÌÇÐÄvlogÈë¿Úworks through studies to assess the feasibility of developing a mine at Jadar.
