The song "Chambishi Copper Mine," belted out by workers at a Zambian copper mine, has gone viral online thanks to its rousing tune. Many viewers said the energy rivals that of a World Cup anthem.

The track was created and performed by employees of NFC Africa Mining Plc (NFCA), a China-Zambia mining company under China Nonferrous Metal Mining Group.

Chambishi is a century-old copper mine that once fell into disuse before resuming production following Chinese investment and modernization efforts.
