Project Overview

The 67 km2 Amsa project is comprised of five license blocks located in northern Morocco, approximately 105 km southeast of the capital Rabat, 155 km east of the port city of Casablanca, and 8.5 km southwest from the Achmmach tin deposit currently being developed by Kasbah Resources Ltd. Aterian holds a 100% interest in the project which is accessible via a number of asphalt roads and a network of motorable tracks. 

Amsa is located in the highly prospective Central Moroccan Hercynides, which is host to numerous active and historic mines and development projects including the El Hamam fluorite mine operated by the state mining group Managem. The Central Moroccan Hercynides are dominated by numerous large granitic plutons that intruded into a sequence of Ordovician to Devonian aged sediments and is considered highly prospective for copper, tin, tungsten, lead, zinc, and fluorite mineralisation associated with Hercynian age intrusives. 

The project comprises a lower Carboniferous (Namurian) age turbidite sequence of folded and deformed, interbedded mudstones and sandstones, intruded by magmatic sills, located off the eastern margin of the Oulmes granite. The metamorphic aureoles of Hercynian age granites are known to host base metal deposits and occurrences in the region.

Exploration Programme

Altus selected Amsa based upon an extensive process of desk-based prospectivity mapping. This work comprised a review of available datasets including historical mineral occurrences, geological maps and satellite borne remote sensing data. The project is cut by a series of northeast-trending structures that are historically mapped to strike towards the El Hamam fluorite mine, and the Achmmach and Bou El Jaj tin deposits.

A first phase reconnaissance exploration programme is due to commence shortly and will include an assessment of priority targets identified that includes northeast-trending structures interpreted as along strike of historically mapped tin, zinc, and lead occurrences.
