Magotteaux reaches majority stake (51%) in GMSA, expanding its presence in the South African grinding balls market

Thursday 20th July | 2023

Magotteaux, a global leader in high-performance grinding media, is pleased to announce the successful acquisition of 36% of the shares of Grinding Media South Africa (“GMSA”), reaching a majority stake (51%) in GMSA, a prominent company manufacturing grinding balls in South Africa. This acquisition marks a significant milestone in Magotteaux’s longstanding association with the South African market, solidifying its position as a leading player in the industry.

Magotteaux has a rich history of collaboration in South Africa, dating back to 1984 when the company established a long-term technical and commercial agreement with Scaw, a local industry giant renowned for manufacturing a wide range of products, including castings and grinding balls. Following Scaw’s division into four separate entities in 2012, Magotteaux acquired in 2018 a 15% equity share in GMSA and assumed the general management responsibilities of the two plants.

Over the years, Magotteaux has diligently overseen the marketing and distribution of GMSA’s products through its local sales team in Magotteaux Pty, firmly establishing a strong market presence in Southern Africa. The region, particularly South Africa, has been an essential market for Magotteaux’s high-quality grinding media products, largely owing to the extensive presence of major mining companies.

GMSA has an impressive total capacity of approximately 200,000 tons of grinding media, showcasing its significance in meeting the demands of the market. Last year GMSA generated sales for approximately $175 million. With the acquisition of a majority stake, Magotteaux reinforces its commitment to delivering cutting-edge solutions to the mining industry, leveraging its extensive expertise and innovative technologies.

After the acquisition of the majority stake, Magotteaux remains in partnership with its two equity partners, IDC and Main Street, ensuring a seamless transition and continued support for GMSA’s operations and growth.

We are thrilled to take this momentous step in our longstanding partnership with the South African market,” said Gonzalo Cavada, CEO of Magotteaux. “The acquisition of the majority stake in GMSA allows us to further cement our position as a key player in the grinding media industry in the region. We look forward to combining our strengths and resources to continue providing top-notch products and services to our valued customers in the mining sector.

With this strategic acquisition, Magotteaux is poised to reinforce its commitment to sustainability, innovation, and customer satisfaction, while contributing to the growth and prosperity of the South African mining industry.
