Approximate location of the Achmmach tin project, owned by Atlantic Tin

Atlantic Tin Limited (formerly Kasbah Resources Limited) is a tin-focused mineral exploration and development company. The company has majority ownership of its Achmmach project in Morocco and has exploration permits for the nearby Bou el Jaj tin project.

The Achmmach Tin Project

Achmmach is considered the most advanced greenfield project in the world, located on the western edge of the El Hajeb province in Northern Morocco. Atlantic Tin is the 75% majority shareholder in Achmmach, with Toyota Tsusho (20%) and the Nittetsu Mining Company (5%) making up the remainder.

The project comprises two tin systems, the Sidi Addi Trend and the Meknes Trend, both approximately 1.6km in length. Cassiterite is found within small but numerous quartz veins associated with silica tourmaline alteration and replacement of shear zones.

Tin was first discovered at Achmmach by the Moroccan government, which from 1991 undertook an extensive exploration and evaluation programme. This was continued by Atlantic Tin from 2007. In July 2018, Atlantic Tin completed a definitive feasibility study (DFS), which superseded a 2016 ‘Small Start Option” (SSO) DFS. In 2021 a review of the resource potential saw Achmmach’s Measured and Indicated contained tin increase by 27%. In addition, Atlantic Tin completed two additional studies: a Pre-Feasibility Study on Dry Stack Tailings at the Achmmach project, outlining Achmmach’s potential to be a multi-decade tin mine, as well as a proof-of-concept study that assessed the potential of constructing a small DC electric arc furnace tin smelter at Achmmach.

Having acquired all the major permits required as well as local support for the project, Atlantic Tin has successfully renewed its mining lease for the Achmmach Tin Project for a further 10 years to January 2032. They intend to complete further optimisation initiatives to further strengthen the confidence and attractiveness to investors as well as looking towards project construction.
