ED'S NOTE
Opening the window on South Africa’s furthest corners
Dear Reader
If you are feeling anything like I am, you will be daydreaming about the year-end holiday, and taking a break from what has been another extremely busy year. I was thinking about my years of visiting the beautiful Wild Coast and realised that we don’t necessarily need itineraries that are prescribed months in advance. Rather, we should be seeking out the odd adventure, looking for more obscure destinations and allowing ourselves to slow down. I came across a newsworthy piece about the potential destruction of some of the most incredible coastline in our beautiful land and thought it was worth sharing.
Xolobeni is a village on a 24-kilometer (15-mile) stretch of wilderness in the Wild Coast region of the Eastern Cape, where a proposed titanium mine is located. It has become synonymous with a two-decade-long fight by the indigenous amaMpondo against extractive mining interests that had sights on the powdered titanium in the dunes. There have also been more recent attempts to conduct seismic surveys for offshore oil and gas.
The day the prospectors came, so did the storm. It was 2007, and clouds barrelled toward the coast, driven by a wind that churned up dust and foretold of the downpour to come. Beyond the rusty dunes, the Indian Ocean surged with equal force. “It was scary,” says Mamjozi Danca, a traditional healer who has lived here all her life.
Her family couldn’t bring the cattle in from grazing, and “even cooking wasn’t easy”. They hunkered down in their rondavel, a round homestead with a thatched roof not far from the mineral-dense dunes of Xolobeni on South Africa’s Wild Coast, to wait it out.
When traditional healer Mamjozi Danca was born into a violent apartheid state that tried to dispossess her people of their land and culture, the amaMpondo fought back. Now they are fighting to protect their heritage from mining corporations.
On the day the mining prospectors came for their sand samples, the storm drove them away, Danca says. It was frightening. But it was a sign, she says, a miracle even. “If we allow [mining], [we] will never be able to access any medicine, the beach, the sea, or food,” Danca says.
When the government later granted a prospecting license to Mineral Sand Resources, an Australian company, the community challenged its legality in court, resulting in the license being suspended.
The amaMpondo want economic development, but on their own terms, with many preferring light-touch tourism over extractive mining. Some families offer rustic catered accommodation for hikers trekking up and down the coast, such as here at the popular Mtentu River mouth.
It’s no accident that this place is well preserved, the locals say. Their custodianship has kept it this way.
The land is their mother, they say; it is their identity, something they respect. In their belief system, the land owns the people; the people don’t own the land. When the amaMpondo speak of “the land”, they aren’t referring merely to the soil beneath their feet, which can yield crops to be sold. They’re talking about the rains that roll in on a storm, and the water filtering into the wetland where the grass aloes grow. They’re talking about the springs where they collect bathwater, the grasslands where their herds graze, and where they gather plants for medicines and mystical charms. They speak of the forests that burst with fruit and offer firewood or timber. They mean the rivers that run into the ocean where they cast their fishing lines, and the fish that nourish them.
Xolobeni’s rusty titanium-rich coastal dunes are synonymous with the amaMpondo’s 20-year battle to keep extractive mining out of their ancestral lands. To add, the Pondoland Centre of Endemism is globally recognised for its unique plant diversity, with rarities such as the Pondoland coconut (Jubaeopsis afra), the Pondoland conebush (Leucadendron pondoense) and the Pondoland ghost bush (Raspalia trigyna).
Despite various challenges, the community’s protests have not stopped. They now continue with a protracted legal battle against the energy giant Shell, which planned offshore seismic surveys about 770 km south of Xolobeni to find oil and gas. So far, they’ve kept Shell’s prospecting license application snarled up in legal proceedings.
The legal case centres around more than just the potential environmental impacts of the sonic blasting, such as injury to sound-sensitive marine life like dolphins, whales and the nearextinct African penguin (Spheniscus demersus). The amaMpondo argue that it’s also a threat to their cosmology.
There is an endlessly rich vein of experiences to be had – not just here but across our stunning country. Let’s look after what we have, so that we have magnificent gems to visit, and a heritage of natural beauty to pass on to generations to come.

HI802 IRIS SPECTROPHOTOMETER
The HI802 iris spectrophotometer quickly identifies Hanna Instruments vial methods by reading the barcode on reagent vials across multiple methods that support the use of a single-zero measurement.
The barcode reader for method identification is removable to allow other methods and cuvette adapters (included) to be used for maximum versatility. HI802 iris portable spectrophotometer allows for measurement in the spectrum of all wavelengths of visible light and not just prespecified wavelengths.
Spectrophotometers work by isolating light at specific wavelengths from white light. This compact meter incorporates several features that facilitate both fantastic performance and exceptional usability:
Automatic method identification of barcoded sample vials
• Removable barcode reader for maximum versatility
Advanced split beam optical system
• Rechargeable li-ion battery
• User customisable methods
Vial barcode reader
Automatic method identification of barcoded sample vials is an exciting feature of the HI802.
The HI802 visible spectrophotometer scans an inserted barcoded vial and automatically detects both method type and method range, significantly reducing the risk of errors and aiding measurement procedure.
Vial rotation
Vial rotation during measurement allows for method identification and for several absorbance readings. The instrument then converts the readings to concentration units and the result is shown on the LCD display. This rotational averaging of signals during measurement (with the lamp on) ensures improved method accuracy.
Shared single-zero measurement
Use of a single-zero measurement across multiple vial methods where blank correction is done with DI water. This ensures that sample features, rather than instrument changes, are reflected in the instrument’s measurements and contributes to ease of use and stable readings.
Universal cuvette holder and autorecognition
The built-in cuvette holder holds both 22mm round cuvettes and rectangular cuvettes with a 5cm pathlength. Adapters for the cuvette holder are available to hold other 13mm and 16mm round cuvettes, and 10mm square cuvettes, including the 13mm vial adapter with barcode reader.
Rectangular cuvettes have longer pathlengths, which result in higher sensitivity in readings of low absorbance samples. Additionally, the meter permits the selection of the size of the cuvette used in custom user methods from the available sizes. For all methods, the programmed cuvette size is displayed on the screen to assure that the proper pathlength is being used by the meter when calculating measurements.
System check
Upon turning on the meter, a performance check occurs to confirm that the light source is working properly and to calibrate the position of the grating. The grating calibration works by scanning for the ‘zero order’ light reflecting off the grating. If any mechanical problems are present, the meter will display an alert. This feature establishes confidence in measurements, knowing that the meter is always working properly without needing to run any additional tests.

LAB WEIGHING SOLUTIONS FOR THE MINING INDUSTRY MINING
The fire assay method is the accepted standard method for determining the amount of precious metals such as gold, silver and platinum in metal ore. In assay laboratories and mines, weighing regulus, lead buttons and ore samples require accurate and reliable instruments.
Weighing is crucial in the fire assay process since errors in the measurement of the sample or gold bead can have significant financial implications. To ensure accuracy, many assay laboratories use high-resolution analytical balances to determine the exact weight of the original sample and microbalances to weigh the final gold bead. With several samples being analysed simultaneously, the process requires meticulous care to ensure correct sample tracking.
Unmatched accuracy and reliability
METTLER TOLEDO‘s Excellence balances offer unmatched accuracy, robustness and longterm reliability in the harsh weighing environments of precious metal mining companies and refineries. Specially designed accessories and LabX One Click weighing solutions make weighing secure and sample handling much easier while providing fast results. The fire assay method is a differential weighing procedure that can be
customised and stored in the LabX software of the balance according to individual process requirements.
Convenient and accurate regulus weighing for assays
METTLER TOLEDO’S micro and ultra-micro balances offer low repeatability and short stabilisation times, ensuring reliable and fast
weighing of precious metal samples for fire assay applications. A specially designed funnel set allows accurate weighing of even the smallest samples, such as prill and regulus, in a very short time.
Simple and efficient sample handling
Tare containers of all shapes and sizes can be securely positioned on the XPR range of
balances with ErgoClips – the special tare container holder. This allows direct dosing of precious samples into the desired vessel, minimising sample loss and resulting in simple and efficient sample handling.

YOUTH SPEAK OF MAKING A CLEAN LIVING OUT OF ‘WASTE’
Young entrepreneurs have opened up about the highs and lows of making an honest living in the waste management sector during an event marking Youth Skills Day.
Petco, South Africa’s longest-standing producer responsibility body (PRO), hosted the event under the themes of climate action and the opportunities for youth working in the collection and recycling industry.
“South Africa has one of the highest youth unemployment rates in the world, so it is imperative that we bridge the skills gap and create equal opportunities for youth,” Petco marketing manager Kara Levy told attendees at the event in Killarney, Johannesburg.
Addressing attendees, waste sector entrepreneur Mogomotsi Msumba described how he used to watch his mother collect recyclable materials and sell them to recycling buy-back centres in order to put food on the table. Later, when he could not pay his university fees and had to drop out, he, too, ventured into the collection and recycling industry – opening the Circle of Hope buy-back centre in Orlando West in 2014.
“Recycling is not for the faint-hearted. It’s a tough industry,” said Msumba, who lost everything when his business burnt down in 2019. “If you don’t manage incoming and outgoing volumes, you’ll also lose money. And I did.”
Msumba was quick to acknowledge that support from Petco carried him through difficult times, even when his own family didn’t want to support a losing business. “You cannot do it alone,” he said.
Circle of Hope now works with the CSIR and the Department of Forestry, Fisheries and the Environment to create new products from recyclable materials which have been discarded as waste. “There’s a lot of waste and a lot of work. Everyone can be a player.”
Harriet Matjila, who started out in the sector as an informal waste picker before launching her company, Makhabisi Recycling
and Trading, finds it “puzzling to hear people complain about a lack of jobs”.
Since 2020, Petco has supported Makhabisi Recycling with a six-metre trailer for collecting recyclable materials, a baling machine for compressing recyclable materials before on-selling them to recyclers, a Covid relief grant, business branding, and personal protective equipment.
“It’s up to you as an individual, and waste is a large and growing industry,” said Matjila, whose buy-back centre employs 45 people.
The business allows her to support her family while also creating income streams for other waste pickers in the Boksburg area.
“It’s been the best experience ever. I’ve discovered a hidden talent in myself,” said Matjila.
Lindiwe Dys, of Lindithando Construction and Projects buy-back centre, said she used to be embarrassed when her parents, who worked as waste pickers, asked her to help them collect recyclable materials for on-selling to buy-back centres.
Today, Lindithando Construction and Projects has 50 employees who help process the recyclable materials brought in by waste pickers.
The company, in turn, sells these to recycling companies.
“I’m so proud. It’s a hard and lonely journey, but you have to be patient and believe you can make it,” said Dys, who encouraged up-and-coming waste entrepreneurs to “go out and make it happen for yourself”.
Former teacher Eva Mokoena, representing the waste picker body African Reclaimers Organisation (ARO), said more and more young people were entering the sector.
“People think that working in recycling is demeaning, so it’s encouraging to see more young people becoming interested in the industry,” she said.
“People think the government owes us, but we owe it to ourselves to improve our lives, and you can’t do that if you sit on the side of the road. You have to rely on yourself to change your life for the better,” said Mokoena, who has raised five children with the money she earns from the sector.
