Kalana Project

The Kalana project is owned by Societe d’Exploitation des Mines d’Or de Kalana S.A. (Somika). Avnel has an 80% equity interest in Somika and the Malian government holds a beneficial interest in the remaining 20%, which has anti-dilution and free-carry rights. Somika owns and operates the Kalana gold mine, a small, Soviet-era, underground gold mine and holds the rights to the Kalana exploitation permit, a combined exploitation and exploration permit that is subject to the 1999 mining code and is unique in Mali. The permit covers a surface area of 387.4 square kilometres and was last renewed in 2003 for a term of 30 years. This permit is host to 29 exploration targets, including the Kalana Main project, the company’s flagship development-stage project, which is the subject of the DFS.

Kalana Main definitive feasibility study

The DFS was led by Snowden Mining Consultants Pty. Ltd. with the support of several leading consulting firms, all of which have extensive experience in Mali, including Ivor Jones of Denny Jones Pty. Ltd., DRA Projects (Pty.) Ltd. and Epoch Resources. The key performance indicators reported in this news release are based upon 100-per-cent ownership of the Kalana Main project.
