Overview of operations
During 2020, the Group completed its initial high level exploration programme over its portfolio of mining concessions covering an area of over approximately 1,500 hectares, to develop and direct future exploration work.
As at 30 June 2020, the Company held 12 fully owned mining concessions in Mexico, a 51% interest in the Hamersley Iron ore projects in Australia and is in the process of acquiring 100% of Elizabeth Hill Silver project in Australia. An initial LOI to acquire the Andromeda tenement adjacent to San Celso Project in Mexico is also in place.
Copper / gold project
Donovan 2 project
The Company’s 750-hectare Donovan 2 flagship project is located to the southeast of Zacatecas city and in close proximity to Alien’s portfolio of other wholly owned projects along the Mexican precious and base metals belt. The Teck Resources San Nicolás copper zinc deposit and Minera Frisco El Coronel gold mine are both located within 25km.
Alien Metals’ preliminary exploration programme on this project, has identified several areas that exhibit pathfinder indicators of volcanogenic massive sulphide (VMS)-style mineralisation, and ground magnetic geophysics and induced polarisation have confirmed indications of sub-surface VMS-style mineralisation.
A maiden drilling programme is being finalised to fully test the main targets.
Silver projects
Elizabeth Hill (Option to acquire 100%)
The Elizabeth Hill project is situated approximately 45 km south of Karratha in the 61,000 km2 Achaean Pilbara Block of the Pilbara Craton. The Project is well located, lying 40 km from the deep-water port at Dampier and 8 km from rail infrastructure.
The Elizabeth Hill Silver Project was mined between 1998 and 2000 via underground mining, primarily between the 62 m and 102 m levels. Silver production totalled approximately 16,800 tonnes of ore grading 2,195 g/t Ag (70.24 oz/t Ag) generating 1,170,000 ounces Ag, including some very large specimens of native silver.
Los Campos project
The Los Campos project comprises four concessions covering an area of approximately 500 hectares and is located on the south side of the city of Zacatecas and bounds the Endeavour Silver El Compas gold mine. The property encompasses at least two known veins: the Los Campos vein and the San Rafael vein and is easily accessible by a short drive from the centre of the City of Zacatecas.
The Los Campos vein systems have been developed along a strike distance of over 3km and to depths exceeding 100m. Historic geological mapping and sampling has identified the potential for additional veins running either parallel or nearly parallel to the Los Campos vein.
