Addana Project
The Addana Project is a silver and lead, polymetallic deposit located in a district that has seen lead and silver mining for hundreds of years. Numerous high-grade veins can be seen from surface over an area over 40 km in strike length. The veins vary in length from 15m to 2.5km, generally about 40cm thick, often only a few metres and possibly amenable to the use of bulk open pit mining methods.
Historical mining was done using hand tools to a depth of up to 10 metres. Historical tax data from the area shows that taxes were paid on 600 tonnes per year of raw ore extracted from the area, divided into 3 categories of material:
- Al Quifox ore (80% lead and 1200g/t silver)
- Amjoute ore (65% lead and 750-900g/t silver)
- Basic ore 50% lead and 600g/t silver.
Grab samples collected by Trigon from historic waste material:
- T1 – 317 g/t silver and 22.6% lead
- T2 – 99 g/t silver and 9.5% lead
- T3 – 564 g/t silver, 24.8% lead and 5.3% zinc
The Addana Project is located near Akka, in the province of Tata, located about 300 km from Agadir on the road connecting Agadir to Tata. The Addana Range was formed by an anticlinal fold in the Bani series of quartzites and schists, of Ordovician age.
