The company, which operates out of Sierra Leone, put the results primarily down to higher sales volumes during the period, which were up 48% on the year before.
This was coupled with an extremely strong pricing environment, which saw a 341 % increase in average rutile prices on the first half of 2011.
The only cloud on the horizon was the impact of Sierra Rutile having to stockpile zircon during the period, compared with the 5,900 tonnes it sold the previously.
The results showed a step change in production, with a 57% increase in rutile production to 42,610 tonnes.
Rutile is predominantly used in the manufacture of white pigment for paint and plastics.
There was also a 67% increase in ilmenite production to 10,315 tonnes.
"With our continued strong production from existing assets and the introduction of our growth projects, scheduled to deliver significant production increases over the coming years, we are extremely well positioned for the future," said Chief Executive John Sisay.
