The Ngwenya Mine is located on Bomvu Ridge, northwest of Mbabane and near the northwestern border of Eswatini (Swaziland).

[7] The Swaziland Iron Ore Development Company (SIODC), owned by the Anglo-American Corporation, started mining of the deposit in 1964.

[9] There was a plan to revive extraction activities in the mine, but the price of iron ore fell, making the project hardly profitable.

[1] The building was donated by the Republic of China in Taiwan, and some ancient tools displayed in the center were recovered with the help of the European Union.

Among many environmental issues, the mining operations are a threat to Disa intermedia, a protected orchid growing exclusively in the region.

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

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

[14] In January 2018, the Mineral Management Board announced it was ready to relaunch prospecting activities at the Ngwenya mine.
