Libya's National Oil Co. (NOC) has sold Sirtica crude via tender, traders said on Friday, making it the third of the country's crude oil grade to be available to the market since the ousting of Muammar Gaddafi.

Traders said 600,000 barrels of the light crude for November loading has been sold to a U.S. oil company, which could not be reached to confirm the deal.

Price details were not available.

The loading port is Marsa al Brega in eastern Libya.

Prior to the sales of this Sirtica cargo, only Sarir and Mellitah crude and condensate were exported from Libya.
