Sierra Leone's mineral wealth is extraordinary — world-class diamonds, iron ore, rutile, bauxite and gold in a country the size of Scotland. The infamous 'Blood Diamond' era is history. Today's mining sector is transformed, though challenges remain. Here are the facts.

Sierra Leone's Diamond History

Diamond mining began in 1930 and diamonds financed Sierra Leone's civil war (1991–2002), giving rise to the term 'Blood Diamond' and the 2006 film. The Kimberley Process Certification Scheme (KPCS), introduced in 2003, was designed to break the link between diamonds and conflict financing. Sierra Leone is now a full KPCS member.

Current Diamond Production

Sierra Leone produces approximately 500,000–700,000 carats annually through the National Minerals Agency (NMA) licensing system. Mining ranges from artisanal alluvial mining (individuals with basic equipment in river beds) to industrial operations. The Star of Sierra Leone, at 968.9 carats, was one of the largest gem-quality diamonds ever found.

Iron Ore — Tonkolili and Marampa

The Tonkolili iron ore deposit in Tonkolili District is among the largest untapped iron ore reserves in the world — estimated at over 10 billion tonnes. African Minerals and then SL Mining have operated there. Marampa iron ore (Sievert Storey area) is a separate deposit. Both have had periods of operation and suspension tied to global iron ore prices.

Rutile — Sierra Leone's Titanium

Sierra Leone is a leading global producer of rutile (titanium ore), found in the Bonthe District. Sierra Rutile (now Iluka Resources) operates the main mine. Rutile is used in titanium metal and as a whitening pigment. This is the most consistently operational of Sierra Leone's mining operations.

Mining and Local Communities

The relationship between mining companies and local communities is complex. Surface rent payments, environmental impacts, and employment are constant flashpoints. The government has increased local content requirements. Community Development Agreements (CDAs) are now mandatory for large operations.

Investing Near the Mining Sector

For investors who aren't mining companies: opportunities in logistics, accommodation, catering, maintenance services and professional services around mining operations are substantial. The Tonkolili region, for example, created demand for food supply, transport and accommodation services across a 200km corridor.
