Niobium is not a metal most people can picture. It is soft, silver-gray, mostly invisible to consumers, and essential. A pinch of it added to steel turns an ordinary alloy into the kind used in jet engine blades, gas pipelines, and the superconducting magnets that run MRI machines. Most of the world's niobium comes from a single mine in Brazil. Any alternate source is strategically interesting. In northern Malawi, about 250 kilometers north of the capital Lilongwe, the Kanyika deposit holds what is considered one of the largest niobium mineral resources in the country, an estimated 60 million tonnes of ore grading at 0.29 percent niobium metal. For nearly two decades, that geology has collided with the lives of 243 Malawian families who happened to live on top of it.
Prospecting at Kanyika began in 2006, when Globe Metals and Mining, an Australia-based company listed on the Australian Securities Exchange, received an Exclusive Prospecting License from the Malawian government. The initial plan was a joint venture with Thuthuka Group, a South African engineering firm. The deal shifted in 2010 and 2011 when East China Mineral Exploration and Development Bureau, a state-owned enterprise based in Nanjing, invested roughly 47 million US dollars and acquired a 51 percent stake in Globe Metals. In 2012, the China Development Bank issued a letter of intent to finance the project. The geological work continued. Bulk sampling was completed in early 2014. Forty tonnes of crushed ore were shipped to the Guangzhou Research Institute for Non-Ferrous Metals, where a pilot plant was built to prove the processing method. In 2021, after years of negotiation, the company obtained a license to conduct large-scale mining.
Kanyika is designed as an open-pit operation, a vast terraced hole from which ore would be trucked to an associated refinery, also to be built. After processing, the end product would be mostly ferroniobium, the alloy form used by steelmakers. Globe Metals and Mining's executive director, Neville Haxham, has said the project will create more than 1,200 jobs and improve the economic standing of the local population. For Malawi, which currently runs only one other significant mine, the uranium-focused Kayelekera, Kanyika would be the country's second-largest mining operation. The economics, if they work, are not trivial. Niobium prices are set on a tight global market, and a new African source could reshape supply chains that currently run almost entirely through Brazil.
The project's environmental assessments raised concerns that deserve to be taken seriously. Water drawn from borehole wells in the Kanyika area already contained levels of uranium above World Health Organization recommendations, before any large-scale mining. Local reporting from The Nation Online during the 2010s carried headlines like "Killer water at Kanyika Mine" and "Hunger overshadows Kanyika mine." The underlying chemistry here is ordinary. Niobium deposits often carry uranium and thorium as secondary minerals, and disturbing those deposits on an industrial scale tends to mobilize the radioactive elements into groundwater. The assessment process proposed monitoring and mitigation. Whether monitoring and mitigation will match the actual impact is a question no one can fully answer until the pit has been running for a decade.
The human story of Kanyika is not yet resolved. Civil society organizations, including the Catholic Commission for Justice and Peace and ActionAid, have pushed hard for residents who will be displaced by the mine to receive adequate consultation and fair compensation. Inkosi Mabilabo Jere, a Senior Chief of Mzimba, and John Alphonsus Ryan, Bishop of Mzuzu, have both publicly criticized the government's handling of compensation for affected local families. In August 2017, a lawsuit was filed in the regional capital Mzuzu on behalf of 243 households. The households claimed they had not been adequately compensated for being displaced by the mine. At a 2018 mediation hearing, a key issue was land that had already been disturbed during the exploration phase, before the large-scale mining license had even been granted. These are farmers, many of them subsistence growers, whose families have worked the same fields for generations. Their legal case is not an obstacle to development. It is a reminder that development without fair compensation is a form of taking.
Kanyika sits at the center of a set of choices that African governments and foreign investors are making across the continent. Chinese state-owned enterprises and development banks are putting up the capital. Australian junior mining companies provide the licenses and technical expertise. Malawian villagers live on the surface. Everyone involved says they want the mine to benefit everyone. How that gets measured, and by whom, is what the courts in Mzuzu have been trying to sort out. The ore will still be there in ten years. The question is whether the communities on top of it will have been made partners in what the ore becomes, or, as so often in mining history, witnesses to wealth that traveled through their land without staying.
The Kanyika deposit lies at 12.70 degrees South, 33.67 degrees East in Mzimba District, Northern Region, Malawi, about 250 kilometers north of Lilongwe on the central Malawian plateau at roughly 1,300 meters elevation. From 4,000 to 7,000 feet above ground, the prospect area is visible as cleared exploration pads and access tracks within surrounding miombo woodland and maize cultivation. The nearest airport with published identifier is Mzuzu Airport (FWUU). Visibility is typically clear from May through October during the dry season.
