Realizing the object's unique artistic craftsmanship, the mine clerk, Lieutenant-Colonel John Dent-Young, preserved the sculpture and later presented it to the Department of Mines Museum in Jos. Subsequent excavations across the Jos Plateau revealed that the Nok civilization flourished between 1500 BC and 500 AD, producing sophisticated terracotta sculptures and pioneering iron-smelting technology in West Africa.
