Vein-type lead-zinc deposit, consisting of (1) several large NE-SW trending sulphide-dominated veins, up to 40 m thick and 13 km long, and (2) smaller baryte-fluorite dominated veins, up to 10 m thick, trending NE-SW and E-W. The veins are mainly hosted in Paleozoic rocks.
This deposit has been operated by several French companies from 1923 to 1960.

Aouli is about 26 km (16 mi) NE of Midelt by road. It formed part of a large Moroccan lead ore mining area (Haute-Moulaya) active from around 1926 until 1975. It is made up of a vein-shaped deposit with the most important veins at Aouli, Sidi Ayad and Sidi Said (approximately 60-80 veins in total). The basement consists of Paleozoic schists into which granites intruded. The top layers are Permo-Triassic (sandstones, arcs and conglomerates as well as basalts and trachytes). The ore-bearing tunnels (with a few exceptions) extend in slate. The Aouli mining area is known for collecting grades of azurite, malachite, galena, baryte, coronadite and fluorite.

The fluorite is mostly clear to pale yellow, in cubic crystals up to 1-7 cm, and commonly sitting on quartz/baryte. The most spectacular fluorites originate from Sidi Ayad and Sidi Said, with the more beautiful fluorites erroneously labeled “Aouli” coming mainly from the Sidi Ayad veins located in the north of the district in the middle of a desert area, which is really only accessible by 4x4 vehicles.

From time to time local residents resume small operations and manage to get out some of the fluorite from the abandoned and cleared tunnels. In the main vein at Sidi Ayad local people work in formerly exploited parts, which makes them very dangerous places (falling rocks, presence of wells, etc.). Whilst there are other veins that have produced fluorite they are much smaller. As elsewhere in Morocco, people work only with chisels and hammers, without protection. In addition, it should be known that, as for all of the veins at Aouli, working on them is in principle prohibited since the permits belong to private companies, although the Aouli veins were not actually exploited for fluorite but for galena. Fluorite is found in relatively large quantities in the dumps. A few older (former) miners still go to the old quarries to break galena (used as "khol" for eye makeup).

Unfortunately the main veins located in the south of the district are very poor in fluorite and for mineralogical specimens in general. In fact, the presence of fluorite is linked to the proximity of the Moulouya granite. Whilst the fluorite as a whole is relatively rare at this locality, crystals are quite common. Unfortunately, they remain small in size (usually 1-3 cm, maximum 10 cm) and their entanglement makes them difficult to extract without damaging them.
