The Donovan 2 property is located just over 20 km west of the San Nicolas VMS Copper deposit of Teck Resources, with a current resource of 108Mt @ 1.16%Cu, 1.6%Zn, 0.43g/t Au and 24.5g/t Ag, and only 10 km from El Coronel Silver/Gold mine (Carlos Slim)
The project is situated in a flat lying area of mainly crops with excellent access and local infrastructure, located about 45km south east of Zacatecas, the regional capital. With very scant in-situ outcrop the completed ground geophysics along with initial mapping and surface sampling has been critical to identify the underlying source of the surface float samples containing significant copper mineralisation.
Several copper and sulphide bearing float samples were located from a hand dug water well located proximal to the ground magnetic anomaly defined from work performed by the Company in 2019. It is interpreted that these samples were from the well rather than having been transported from elsewhere as earlier samples taken from inside the well also returned significant copper mineralisation. An isolated float sample that returned 2.68 g/t Au was also collected on the south eastern boundary of the tenement in 2019.
All the historic geophysical data combined with all field mapping and surface sampling to date is being reviewed to plan next stage exploration. Alien have commissioned an independent specialist group who have previously worked on the San Nicolas deposit to provide further insight and recommendations for next stage work.
The Company believes that the IP anomalies, coupled with the earlier geophysical work and the surface sampling results, represents a highly compelling VMS target that warrants follow-up drilling on the Los Alomos and the Cerro de la Cruz targets.

Alien has commissioned TMC EXPLORACION, S. R.L. de C.V. of Mexico over the last 18 months to complete a ground Magnetic Survey, an initial limited Ground Induced Polarisation (IP) survey plus 2 lines of Ground Gravity Survey and more recently a larger IP survey to aid in defining a coherent drill target or targets.
Alien have completed 2 separate field mapping and sampling programs in the same period and all results have been compiled to define next stage work.
Alien are planning to submit the complete data to a globally accredited third party consulting group who have worked on the San Nicolas TECK project to re-interprete all results and give their experienced recommendations for the next stage of the project.
With the project being only 20 some kilometers from the TECK deposit and with already identified similarities with geology, mineralisation and geophysical responses Alien believe that the Donovan 2 project has great potential to host a VMS deposit and are working towards defining such.
