Observatório da Mineração is a brand dedicated to investigative journalism, critical analysis, research, and mentoring in the mining sector. Founded in 2015 by journalist Maurício Angelo, they focus on investigating the role of mining in the global climate crisis and energy transition. Their expertise lies in critical minerals, illegal mining, megaprojects, multinational companies, and the impacts of mining in various Brazilian biomes, particularly the Amazon and the Cerrado.

They specialize in covering political movements, government actions, environmental licensing, legal changes, and the role of the judiciary. The brand reports on how indigenous peoples, traditional communities, and entire cities are affected by mining projects. They also map out the financiers, investors, and the entire extraction, production, distribution, and global export chain, shedding light on key players and analyzing their practices.

They have been at the forefront of investigating two major mining disasters - Mariana and Brumadinho - providing in-depth coverage. As an observatory, they have produced exclusive investigative articles and reports, which have led to investigations by the Ministry of Public Prosecution, official inquiries, and suspensions of mining operations. Their groundbreaking studies have exposed billions in unpaid taxes by mining companies and their role in encroaching on indigenous lands.

They have also uncovered the lobbying network of mining and illegal mining activities in the government and Congress. With their expertise and unique access to data, they report on various aspects, such as the impact of mining on indigenous territories, labor conditions, worker health during the Covid-19 pandemic, and the mining and steel industry's contribution to CO2 emissions, climate crisis, and energy transition. Their impact has been recognized by reputable organizations and they have formed partnerships with major media outlets, such as UOL, Mongabay, El País Brasil, The Intercept Brasil, and many others.

They have also actively participated in global events, sharing their knowledge and insights with international audiences.
