History of gold refining in Nigeria

Gold has been a highly valued and sought-after commodity throughout human history. Its allure and scarcity have made it a symbol of wealth, power, and beauty in various cultures. Nigeria, with its rich mineral resources, has a long history of gold mining and refining.

The earliest evidence of gold mining in Nigeria dates back to the 5th century BCE when the Nok culture used gold for adornment and trade. The use of gold as currency was also prevalent in ancient Nigerian civilizations such as the Igbo-Ukwu Kingdom in present-day Anambra State.

In the 19th century, British colonizers further intensified gold exploration in Nigeria, leading to significant discoveries of alluvial gold deposits along river channels and streams primarily in the north-central part of the country. This sparked an official interest in developing large-scale commercial mining operations.

However, it wasn’t until 1933 that formalized exploration for gold began under the Gold Mines Development Scheme initiated by the British colonial government. This marked the beginning of modern-day gold mining activities in Nigeria.

The first refinery to be established for processing raw materials into refined gold was established by Nigeria’s premier oil company, Shell Petroleum Development Corporation (SPDC) at Owerri during this period. It was designed to cater to local demand but could only refine small quantities.

In 1950, another refinery – The Nigerian Gold Refining Company Ltd (NGRC) – was set up at Jos with a capacity to process up to 1 tonne per day from locally mined ores or bullion brought from other West African countries such as Ghana and Mali.

With increasing global demand for petroleum products after independence from Britain in 1960, SPDC divested its non-oil assets including its Owerri-based refinery which became defunct while NGRC continued production until its closure due to economic challenges around 1976.

The federal government then took over NGRC’s facility under the National Steel Development Authority (NSDA) and renamed it Nigerian Mining Corporation in 1977. However, due to poor management and inadequate funding, the refinery eventually shut down in 1991.

In recent years, there has been a renewed interest in gold mining and refining in Nigeria with the establishment of new refineries such as Wigmore Trading’s facility. This is a welcome development as it will not only provide jobs and boost the economy but also help reduce illegal mining activities prevalent in the country.
