The main resource of the village of Humain may well have been agriculture; marble mining was nonetheless an equally important economic factor thanks to the extension of the pink marble quarry that opened in 1732. The Saint-Hubert abbey ran the Saint-Martin quarry (on the road between Aye and Humain) until 1760. The marble was chiefly used to decorate the Saint-Hubert church and abbey.The quarry was abandoned in 1975.
