Snapshot	Achmmach Tin Project is blessed with a world-class tin resource endowment. On the 5th August 2024, Atlantic Tin completed the acquisition of Société Anonyme d’Entreprises Minières (“SAMINE”). SAMINE owns the past-producing El Hammam mine, including its infrastructure and tenements, located adjacent to the Achmmach Tin Project. In May 2024 a Scoping Study was completed which incorporates the benefits of combining Achmmach with the nearby El Hammam processing facility owned by SAMINE. The Scoping Study demonstrates the integrated project to be a low-cost, long-life producer of clean and high-grade tin concentrate on the doorstep of Europe. Ore will be mined underground at Achmmach and transported by road 7km to the El Hammam mine for treatment to produce tin concentrate.

Summary:

Morocco is subdivided into several geological domains, demarcated by regionally extensive Palaeozoic faults. These domains, from south to north include the Anti-Atlas and the northern limit of the Saharan domain, the Meseta Atlasic domain and the Rif domain. The Palaeozoic basement of the Meseta Atlasic Domain (includes the Moroccan and Oran Meseta, or Western and Eastern Meseta respectively) are exposed as isolated massifs encompassed by Mesozoic – Cenozoic sediments. The Achmmach deposit is in the Central Massif of the Moroccan Meseta and hosted within the turbiditic sediments of the Serpukhovian aged Fourhal Formation.

Geologically, the Achmmach sector is part of the Moroccan Massif Central which constitutes the largest Paleozoic unit of the Moroccan meseta which extends from the coast of the Atlantic in the West to the foot of the Middle Atlas (Azrou-Khénifra region) in the east. To the north it is limited by the Saïs basin (Meknes basin) and to the south it disappears under the plateaus of the phosphates.

This fragment of the chain was built during several superimposed tectonic episodes. within an anchiepizonal regional metamorphic level.

The Paleozoic terrains are intruded by numerous Hercynian granite massifs, late-tectonics, the main ones being from the West to the East: the massifs of Zaër, Oulmès and Ment as well as the granite points of Moulay Bouazza, El Hammam and J. Aouam. The general structure, produced by the major Hercynian phase, of the entire Massif Central is summarized in a succession of anticlinorium’s and synclinoriums separated by mega faults which played at the basin boundary in the Carboniferous, and in shear during the late-Hercynian compressions.

The Achmmach tin deposit is an epigenetic vein-stockwork-breccia style deposit which is associated with a strongly boron enriched paleo hydrothermal system. It is comprised of fine-grained cassiterite with associated minor sulphide minerals in a tourmalinised sandstone/siltstone host. It is interpreted as being hosted by two cross-cutting swarms of tourmaline-altered zones: a series of east-west striking sub-vertical zones described as “feeders” and a stacked series of oblique gently to steeply northdipping “branches.”

Achmmach mineralisation is localized in two sub-parallel E-NE striking lodes named the Meknès and Sidi Addi trends, separated by approximately 500m (Figure 5). Meknès comprises the largest part of the Mineral Resource. Mineralisation is developed within the tourmaline-silica altered metasediments. Tin mineralisation occurs primarily as cassiterite with minor stannite. It is pure in composition and does not carry significant trace elements.

It is an epigenetic vein-stockwork-breccia style deposit. It is comprised of fine-grained cassiterite with associated minor sulphide minerals in a tourmalinised sandstone/siltstone host. The 1.6 km strike extent of the mineralisation system is hosted by sequences of folded and metamorphosed shales and sandstones. The lodes in Meknes form a 300m wide array across strike with individual lode structures ranging in width from 1m to 30m. Tin mineralisation occurs primarily as breccia infill and quartzcassiterite veins and has been defined in diamond drill holes to a vertical depth of up to 600m below natural surface. The bulk of the known mineralisation intersected by the current drilling occurs between 1,000m RL and 700m RL. Mineralisation remains open at depth and along strike.
