London, UK, 9 January 2013: Sierra Rutile Limited (AIM: SRX) ("SRL") is pleased to provide an operational update on developments during the fourth quarter of 2012 ("Q4" or "the Period") and the 2012 year.
Highlights:
· Full-year 2012 rutile production of 94,493 tonnes, a 39% increase on 2011 production;
· Full-year 2012 ilmenite production of 22,008 tonnes, a 38% increase on 2011 production;
· Q4 production of 25,502 tonnes of rutile and 6,378 tonnes of ilmenite, both ahead of budget;
· Lanti Dry Mining construction completed and commissioning commenced on budget and ahead of schedule. First product produced from Lanti Dry Mining concentrator.
· Exceptional new Gangama Dry Mining project announced:
- US$507m pre-tax NPV10;
- 238% pre-tax IRR;
- 8-month project payback; and
- Detailed engineering work and project implementation plan underway.
· Scoping study on Sembehun Dredge completed, providing long-term, low-cost production optionality for SRL with compelling economics:
- US$347m pre-tax NPV10;
- 34% pre-tax IRR; and
- 22-year project life.
Production
Full-year 2012 production was 94,493 tonnes of rutile and 22,008 tonnes of ilmenite, respectively 39% and 38% ahead of 2011 volumes (2011: 67,916 tonnes of rutile and 15,946 tonnes of ilmenite). This strong result was contributed towards by Q4 production of 25,502 tonnes of rutile and 6,378 tonnes of ilmenite.
Expansion projects
Construction of the Lanti Dry Mining plant was completed during the quarter and commissioning commenced. First ore was successfully processed through the concentrator and the concentrate transferred for onward processing in the mineral separation plant. Production ramp-up is continuing.
A significant change in SRL's expansion plans was announced on 31 October 2012 with the completion of a pre-feasibility study into the dry mining of the Gangama deposit ("Gangama Dry Mining). The pre-feasibility study reported an exceptional project with a pre-tax NPV10 of US$507 million, an impressive 238% pre-tax IRR and a payback period of just 8 months.
Furthermore, as it replicates, on a larger scale, the Lanti Dry Mining project that was successfully completed within the quarter, Gangama Dry Mining represents a much lower-risk option of increasing SRL's production to the 200,000 tonnes per annum level. SRL has commenced detailed engineering work and a project implementation plan on the project in order to fast-track its development.
