MACUA's head of media, Magnificent Mndebele, condemned the police tactics used during the crackdown on illegal mining operations at Stilfontein. He highlighted that while miners at Marikana were killed by police, at Stilfontein the community called the police out of desperation, underlining a systemic targeting of the marginalized and a failure to hold the powerful accountable.

On April 9, 2025, MACUA submitted a complaint to the South African Human Rights Commission alleging that the South African Police Service and National Prosecuting Authority have been colluding with mining corporations to protect elite economic interests and criminalise artisanal and small-scale mining.

On March 4, 2025, MACUA publicly criticized the Portfolio Committee on Mineral and Petroleum Resources for excluding it from recent oversight discussions in Mpumalanga. The organization claimed that the omission was a deliberate act to silence communities affected by mining and to protect the interests of the mining elite. Additionally, MACUA reported a potential criminal offence related to the provision of misleading information by the Department of Mineral and Petroleum Resources.

MACUA has accused the Mining Portfolio Committee and the Department of Mineral and Petroleum Resources of deliberately excluding it from oversight discussions and providing misleading data, an action it interprets as an attempt by elected officials to silence mining-affected communities and protect mining interests.

On early April 2024, MACUA, an NGO representing communities affected by mining, accused coal mining company Seriti of non-compliance with regulatory requirements by failing to publish its Social and Labour Plans. The protest, marked by concerns over home damage and health issues from blasting activities, demanded greater accountability and transparency from the mining firm.

MACUA issued a press statement on 28 June 2023 demanding that mining-affected communities be included in discussions regarding mining investments and the energy transition, criticizing the exclusion practices of state and industry representatives.

MACUA, alongside AMCU and WAMUA, joined forces in a legal campaign against the Department of Mineral Resources for bypassing proper consultation with mining-affected communities during COVID-19. A May 2020 court ruling mandated that the department engage meaningfully with these communities, reinforcing their constitutional right to participate in decisions affecting their lives and countering authoritarian exclusion.
