Zama Zama
Michelle Goliath played a major role in establishing the first ethically sourced, fair, women-owned, artisanal diamond process.

Michelle Goliath, a PhD student in the Department of Urban and Regional Planning at the UFS, has a passion for helping the most vulnerable people in society who have run out of conventional employment options. 

“My research includes ‘Zamaism’ psychology, a philosophy which looks at the contestation of space and rules, how people navigate the illegal when they are faced with desperate choices,” she explains.  

Michelle has been working with approximately 3 000 diamond mining ‘Zama Zamas’ (criminal miners) over the past three years. Together, they negotiated an agreement with private sector mining and public sector stakeholders to include the Zama Zamas as legal artisan miners in the formal mining economy.

One of the highlights of her career so far was being part of a big first: the complete, ethically sourced, fair, women-owned, artisanal diamond process.

Michelle explains: “A rough stone includes the story of the women who dig it from the earth, legally (under permit), ethically sourced. Instead of being exploited, the same women now sell their diamonds for full value to a legal tender house through a legal buyer or directly to the cutter and polisher. The cutter and polisher also train the women to cut and polish the stones themselves. The women then sell the stones to jewellery gold- and silver-‘smiths’ who artisanally craft this into an engagement ring or ‘Wakanda gem spear’, to be sold in the open market locally and internationally.”

She believes these products will become priceless works of art. “Like Picasso paintings, they are each uniquely produced by hand with a story and Kimberley process certificates,” she adds.

The story of the women

This project had a big impact on Elisa Louw, a former street seller and domestic worker. She tells her story: “I was tired of domestic work and decided to work at the mines as a Zama Zama. I began with nothing and had to borrow tools and learn from others.”

Elisa started working in the mines in 2013; in 2014, she found her first 75-pointer diamond which she sold for R1 500 on the black market. “The black market was good then,” she said.

She later recruited other Zama Zamas to register and obtain legal permits for mining. Elisa mined from 08:00 to 12:00 and from 13:00 to 16:00 she recruited people to start a legal mining co-op. “It was difficult then. People did not understand what it meant to be legalised,” Elisa explains.

But she worked hard and at the end of 2016, the Batho Pele Primary Mining Cooperative was established.

However, it was a hard and difficult journey before they were given their permits early in 2017. The mines took their IDs and issued them with eviction letters. “They called us names – terrorists, robbers, rapists, etc. But in a meeting with the South African Police Service, the Department of Mineral Resources, the Sol Plaatje Municipality, and the international Swedish Housing Company, Michelle spoke for us.”

“She represented the Swedish Housing Company and we thank the Lord for sending her to us. She informed all parties that we did not want to fight, but that we were looking for a licence to work. She helped us to obtain our legal permit to mine.”

“It was such a relief when we received the permit. I could go home and sleep without worrying about the safety of the old people and children who are mining.

“The permit changed my life as a woman. My voice is heard; my words count. I am proud of myself,” says Elisa. 

The two cooperatives they created, Batho Pele Primary Mining Cooperative and the Women in Artisanal Scale Mining, have already signed agreements with Canada and the USA for the export of fair-trade-certified gem products.

Blood, sweat and tears

The journey towards this big achievement took two years of literally blood, sweat, and tears. “Society labels Zama Zamas negatively as terrorists. In a way, you become a Zama at heart once you live with people every day who are fighting for economic inclusion. You fight the illegal diamond trade that exploited people as digging slaves. You fight formal mining, which is a difficult sector to enter as a woman. You literally fight others with stones for territory. You fight political fights, land fights, the system at every level, to seek an existence,” Michelle explains.

She believes the mining industry can be a tough environment. “It is exploitative at many levels. It showcases rare talent, but under duress. At artisanal scale it is even worse. The only future women have, is to lead themselves, to create their own fairer system, to redesign a full value chain that allows broader participation,” states Michelle.

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
