Disa intermedia is a species of orchid (family Orchidaceae), native to Eswatini, formally Swaziland.

Among many environmental issues, the mining operations have led to heavy pollution of the water sources that feed the nearby city of Mbabane.

Cases of corruption to get the mining license were reported, including a $28 million donation to the king Mswati III by Salgaocar Swaziland Limited Company.

Reports also claimed that Salgaocar was using Mozambican and South African trucks to avoid paying import taxes.

However, in January 2018, the Mineral Management Board announced it was ready to relaunch prospecting activities at the Ngwenya mine.
