The accident happened on Saturday at Nagrire, "leaving eight people dead and five slightly injured," said Bernard Bouda, mayor of nearby Gogo commune yesterday, who travelled to the scene of the tragedy.
The dead were buried on the spot and the wounded taken to hospital in Gogo, a local judicial source said.
The landslide came after heavy rains in the region in recent days, which burst a dyke in the area, the source added.
Such deadly landslides are frequent and the Burkinabe authorities struggle to control gold prospecting in the area, which is carried out by 1.2 million people according to official figures.
Child miners have also become a growing problem in Burkina Faso, where 60 percent of the population is under 25.
