Country Economic Snapshot


Sierra Leone has a land mass of 71,740km² and is bordered on the north and east by Guinea, on the south by Liberia, and on the west by 402km of Atlantic coastline.

The country has a special significance in the history of the transatlantic slave trade. Its capital, Freetown, was founded in 1787 as a home for repatriated former slaves from London and the Americas. Sitting on a coastal peninsula, the city overlooks the Sierra Leone harbour, the world's third largest natural harbour.

It has a population of 8.4 million people and a GDP of US$4.0bn, driven by mining, agriculture, manufacturing, construction and tourism.

Sierra Leone produces bauxite, diamonds, gold, iron ore, titanium minerals and zircon. Australian company Newfield Resources in July 2019 approved the development of its diamond mine, Tongo, at a cost of US$29.4m, which is expected to have a life of eight years and peak production of 260,000cts per annum.

Marampa Mines, a subsidiary of British company Gerald Group, operates the Marampa iron ore mine, in which the government has a 10% stake. Mining operations restarted in September 2021 when the Gerald Group and the government reached an agreement in May 2021 for the company to pay the government US$20m and give it a 10% stake to resolve a royalty payment dispute between them. In May 2022, the mine’s production capacity was increased from 2Mt per year to 3.25Mt. It has a life of 30 years.

Real GDP growth declined to 2.8% in 2022 from 4.1% in 2021 due to the impact of Russia’s invasion of Ukraine, and is projected to increase to 3.1% in 2023 and 4.8% in 2024, driven by the mining sector and the continued recovery of agriculture, manufacturing, construction, and tourism.
