Snapshot	Sembehun is home to one of the world’s largest and highest grade natural rutile deposits. During the First Quarter of 2023, work continued on the DFS, which was released post quarter end. The DFS reinforces the strategic value of the project, and has confirmed that once funded and constructed, the project will significantly extend the Company’s mine life, materially lower its cost structure, leverage existing infrastructure, and generate significant long-term value. The Environmental Protection Agency in Sierra Leone has approved the Environmental, Social and Health Impact Assessment (ESHIA), associated Environmental, Social and Health Management Plan (ESHMP). The approval of the ESHIA and ESHMP is one of the major items required to proceed with the Sembehun project.

Deposit type

• Sedimentary

Summary:

The Sierra Leonean rutile mineralisation is hosted within alluvial and fluvial sedimentary facies of the Bullom Group Sediments. Mineralisation has been derived by the erosion of quartzo-feldspathic gneiss of the Precambrian Kasila group during the Tertiary and redeposited in preincised channel systems and alluvial fans flanking topographically elevated areas of the Kasila Group. The host sediments are typically poorly sorted sandy clay and sandy clays. Rubbly surficial laterite development is prevalent through much of the Bullom Group but does not hinder mining.

If the leading edge of the Sembehun group of deposits is considered as a single mineralised entity then the width of the mineralisation is over 5000m. The deposits length varies from about 1000m to over 6000m. The deposits vary significantly in size from a few mt to over 150mt. In general the mineralisation is present from surface.
