Overview
Titanium Resources Group was the former name of the Sierra Leone mining company now known as Sierra Rutile Limited. Its principal business was the extraction and processing of mineral sands, especially rutile, a titanium-bearing mineral, together with ilmenite, zircon and titanium dioxide feedstock. The company operated in southern and northwestern Sierra Leone, principally across the Moyamba and Bonthe districts, and transported processed minerals to the port at Nitti for export. The company's operating history reached back to mining activity that began in the area in 1967. It was formally established in December 1971 by Nord Resources and Armco Steel. Sierra Leone subsequently became an important source of rutile, and in 1993 the operation was described as the world's largest rutile producer. Production was severely disrupted by the Sierra Leone Civil War, however, and the company abandoned its operations in 1995. Following the end of the war, the business secured a new mining lease in January 2005 covering approximately 580 square kilometres in southwestern Sierra Leone. It began refurbishing the Sierra Rutile mine in 2005 and recommissioned its primary bucket-line dredge, Dredge D1, in early 2006. The company also restarted the SML bauxite project and acquired the Rotifunk mineral-sands prospect. Titanium Resources Group listed on London's AIM market in August 2005 under the symbol TXR. Expansion continued with the commissioning of Dredge D2 in December 2007. The second dredge increased intended production capacity, but it capsized in July 2008, causing two fatalities. Trading in the company's shares was suspended after the accident and resumed in January 2009. The company later reached an insurance settlement and raised additional equity to finance a third dredge and upgrades to its existing processing infrastructure. In 2008 it also sold Global Aluminium Limited, the subsidiary associated with its SML bauxite operation, to Vimetco. The company experienced several governance and financing developments during the following years. Pala Investment Holding acquired a 29.8% interest in 2010. A dispute with the Sierra Leone government concerning interest and other amounts associated with a government loan was resolved in December 2010. In February 2011, Titanium Resources Group changed its name, website and trading symbol, becoming Sierra Rutile Limited. Under the Sierra Rutile identity, the company developed dry-mining operations at Lanti and Gangama in addition to continuing dredge mining. The Lanti dry mine was completed in 2013, while construction of the Gangama dry mine began in 2015 and the facility was declared ready for operation in June 2016. The company also assessed the potential Sembehun deposit and prepared environmental and social management documentation for possible future development. Iluka Resources Limited acquired Sierra Rutile in December 2016. The transaction was reported at A$375 million, with Iluka also assuming approximately A$80 million of outstanding net debt. Following the acquisition, Sierra Rutile became part of Iluka's international operations, and Titanium Resources Group ceased to be the company's operating identity. The historical business remains associated with mineral-sands production in Sierra Leone, local employment and community programs, and the environmental and safety obligations connected with large-scale mining.
History
Mining in the Sierra Rutile area began in 1967, while the corporate enterprise was formally founded in December 1971 by Nord Resources and Armco Steel. The operation developed into a major global rutile producer and was reported to have led world production in 1993. The Sierra Leone Civil War interrupted this trajectory: production was disrupted and the company abandoned the operation in 1995. The post-war redevelopment phase began with a mining lease agreed in January 2005 for approximately 580 square kilometres in southwestern Sierra Leone. Titanium Resources Group announced refurbishment of the Sierra Rutile mine in February 2005, recommissioned its primary bucket-line dredge D1 in early 2006, and worked to restart the SML bauxite project. It also bought the Rotifunk mineral-sands prospect in December 2005. The company listed on AIM in August 2005 under TXR. A second dredge, D2, entered production in December 2007. Its planned capacity increase was substantial, but the unit capsized on 25 July 2008, resulting in two fatalities and a lengthy operational and financial recovery process. Trading in the company's shares was suspended after the accident and resumed in January 2009. The company subsequently raised equity for a third dredge and plant upgrades. In the same broad period, it sold Global Aluminium Limited, which owned the SML bauxite operating company, to Vimetco. Pala Investment Holding took a 29.8% stake in 2010. That year also brought a dispute with the Sierra Leone government over interest and related amounts under a government loan; the dispute was settled in December without the government maintaining the asserted outstanding claims. In February 2011, the company changed its name and trading identity from Titanium Resources Group to Sierra Rutile Limited. Sierra Rutile expanded its mining methods beyond dredging. The Lanti dry mine was completed in 2013. Construction of the Gangama dry mine began in April 2015, and the facility was declared ready for operation on 2 June 2016. The company also advanced plans for the potential Sembehun mine, including environmental and social assessments and an environmental impact assessment licence. Iluka Resources acquired Sierra Rutile on 7 December 2016. The reported consideration was A$375 million, with Iluka assuming approximately A$80 million of net debt. After the acquisition, the Sierra Leone assets operated within Iluka's group and Titanium Resources Group remained a historical corporate identity rather than a current standalone brand.

Products and positioning
A Sierra Leone-focused mineral-sands mining operator whose value proposition was based on high-grade rutile resources, integrated dredging and dry-mining capabilities, export logistics, and the redevelopment of a historically significant rutile district.
Titanium mineral
Rutile
Rutile was the company's signature mineral and the principal product associated with the Sierra Rutile operation. It is a titanium-bearing mineral used as a feedstock in titanium dioxide production and related titanium applications. Historical production made the Sierra Leone operation internationally significant.
Titanium mineral
Ilmenite
Ilmenite was recovered alongside rutile through mineral-sands mining and separation. As a titanium-iron oxide mineral, it serves as an important raw material for titanium dioxide and titanium-related industrial supply chains.
Mineral sands
Zircon
Zircon was among the heavy minerals produced from the Sierra Leone deposits. Zircon is used principally in ceramics and other industrial applications, making it a complementary product to the company's titanium-mineral output.
Aluminium ore
Bauxite
Bauxite was a historical, non-core product associated with the SML Bauxite Project. The related operating business was held through Global Aluminium Limited, which Titanium Resources Group sold to Vimetco in 2008.
