Djebba & Zeflana Zinc
PhosCo is targeting high-grade zinc deposits across two project areas within the highly prolific Atlas belt, a known world-class province for base metals deposits.
The Djebba and Zeflana permits are 16km² each and located 130km by bitumen road south-west of Tunis.
- Djebba – Historical Mineral Resource Estimate of 2.7Mt at 6.1% Zn and 3.3% Pb*
- Zeflana – large surface zinc anomaly defined by Oz Minerals in 2008
The belt has an ancient history of zinc-lead mining stretching back to Phoenician and Roman times though modern exploration has been very limited.
The most extensive exploration in
Tunisia occurred in the period between 2004 and 2008 by companies including Albidon Ltd in joint venture with Zinifex Ltd, and Maghreb Minerals.
The zinc-lead deposits of the Atlas belt are broadly of Mississippi Valley Type (‘MVT), low-temperature carbonate-replacement deposits formed within the Mesozoic-aged broad carbonate shelf sedimentary sequence deposited on the southern margin of the Tethys Ocean.
Most deposits formed during collision, uplift and subsequent extension related to the Atlas orogeny. This style of mineralisation is known to form some very large deposits globally.
*This estimate is a historical estimate and is not reported in accordance with the JORC Code. A Competent Person has not done sufficient work to classify the historical estimate as Mineral Resource in accordance with the JORC Code. It is uncertain that following evaluation and/or further exploration work that the historical estimate will be able to be reported as Mineral Resource in accordance with the JORC Code.
