The government of Niger Republic has launched a formal investigation into the controversial sale of a rare Martian meteorite discovered in the country’s Agadez region, which was recently auctioned in New York for $5.3m, making it the most valuable meteorite ever sold.
According to local media – Aïr-Info Agadez, the announcement was made following a Council of Ministers meeting chaired by General Abdourahamane Tiani, Head of State. Authorities expressed concern that the meteorite’s export may have violated national and international laws governing the protection of natural and cultural heritage.
“This case likely bears the hallmarks of illicit international trafficking,” the government said in a televised announcement.
The meteorite, officially named NWA 16788, weighs 24.67 kilograms and is believed to be the largest fragment of Mars ever found on Earth, approximately 70% larger than any previously identified Martian rock.
It was discovered in November 2023 by a meteorite hunter in the Sahara Desert and later sold at Sotheby’s auction house during its Geek Week event on July 16, 2025.
The Nigerien government has tasked the Ministries of Mines, Higher Education, Public Security, and Justice with conducting a full-scale investigation into how the meteorite left the country and whether its export was authorized.
“We must determine whether this celestial object of exceptional scientific, heritage, and symbolic value was exported in compliance with national and international provisions,” the statement added.
The sale has sparked widespread debate in Niger and across Africa about the traceability of rare geological objects and the need to safeguard the continent’s scientific heritage.
Critics have questioned whether Niger benefited from the sale and whether the meteorite should have remained in public custody.
“It is a crucial matter of sovereignty… This is a national treasure that shouldn’t have been sold,” said Alia Baré, daughter of former Nigerien president Ibrahim Baré Maïnassara.
The Regional Multi-Stakeholder Committee for the Agadez Living Desert Museum has formally requested the meteorite’s return, citing Niger’s commitment to the 1970 UNESCO Convention on cultural property.
The committee urged international cooperation to ensure the rock is displayed in a planned national museum.
“The return of this Martian fragment discovered on our soil would be a powerful gesture of heritage justice and international cooperation,” the committee wrote.
As the investigation unfolds, Niger’s government has pledged to strengthen oversight of rare mineral and scientific discoveries to prevent future losses of national patrimony.
