Donovan 2 Exploration Update

29 April 2019


Alien Metals Limited (“Alien” or the “Company”) is pleased to announce an exploration update for the company’s 100% owned Donovan 2 mining concession.


  • Detailed surface mapping:
    • further supports indications of Volcanogenic Massive Sulphide (VMS) mineralisation on multiple target areas which are open along strike
    • identified zones of alteration indicating the top of a VMS system
    • of low-lying outcrop has identified additional areas of pervasive alteration
  • Sample assays of up to 3.34% Cu and 0.25% Zn
  • Geophysics suggests magnetic and resistive units are correlated at depth below areas of surface mineralisation and alteration
  • Ongoing mapping of historical underground mine workings reveals copper mineralisation
  • Geophysical gravity survey in progress to test for inference of sulphide mineralisation

Peter Taylor CEO of Alien commented: “The district surrounding Donovan 2 is staked by Mexican and Canadian base and precious metal producers. We are delighted to be rubbing shoulders with these mining companies and look forward to updating the market with the gravity survey, further assays and drilling results.”

The Donovan 2 project is located 45 Km southeast of Zacatecas city, Zacatecas State, Mexico. Alien’s geologists collected 44 surface samples consisting of: rock chip, float samples and historic dump samples during a detailed exploration program to complement the geophysics and surface mapping conducted since November 2018. Three samples returned assays in excess of 1000ppm Cu.

Mineralisation at Donovan 2

Volcanogenic massive sulphide ore deposits, also known as VMS ore deposits, are a type of metal sulphide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments. VMS style deposits occur in clusters on the ancient sea-floor. Similar VMS style projects include the Teck Resources Limited San Nicolás Property that lies within 24km of Donovan 2 and reports a National Instrument 43-101 compliant Measured and Indicated resource of 108.9Mt and average grades including 1.16% Cu and 0.43g/t Au.

Surface Exploration

Since commencing detailed exploration activities at Donovan 2 in November 2018, the company has completed detailed mapping on the 746-hectare property. The samples consisted of rock-chip, dump samples from historic workings, and float samples (not in-situ surface samples). The samples are delivering valuable information to guide ongoing targeting efforts.

This has included the identification of two main target areas for follow up work, known as Cerro de la Cruz and El Bordo. Forty-four surface samples were collected and analysed during the mapping and prospecting campaign. Of specific interest are zones of silicification, alunite veining and high-grade quartz float samples at the Cerro de la Cruz target including sample 6872 with an assay of 3.34% Cu. Dump sample 6872 has been traced to historical underground mine workings. The mine has been entered and the copper-bearing structure has been identified. Further detailed mapping and sampling are in progress. The El Bordo target is essentially under soil cover with minimal surface samples.

The results from the Total Magnetic Intensity and Induced Polarity (“IP”) surveys further support and identify the two main targets. Images showing copper assay values and surface alteration, together with resistivity and chargeability 2D inversion models generated using UBC DCIP2D v5 inversion code, have been published on

The objective of the detailed mapping program on Donovan 2 was to provide further supporting evidence of VMS style mineralisation at Donovan 2.

The identification of zones of alteration consisting of alunite veining, chalcedonic quartz veinlets, silicification and traces of kaolinite in combination with anomalous values of copper and zinc are suggestive to be the top of a VMS system. These zones are open along strike to the northwest and southeast. These results based on success of the initial detailed surface mapping allows for a further follow-up geophysical program. A detailed gravity survey is currently in progress over the two target areas. Subject to these results, a drill campaign will be undertaken in Q2.

Standards were inserted approximately every 15th sample in the sample suite and blanks were carefully inserted between mineralised vein samples. Samples were placed in high-density plastic bags and sealed with plastic ties. Samples were stored in a locked warehouse until company geologists delivered samples to ALS Global Preparation Facilities in Zacatecas City, Zacatecas State, Mexico.

Notes to Editors

Alien Metals Limited is an AIM quoted mining exploration and development company. Since the recomposition of the Board and company name change in 2018, Alien has focused on delivering its strategy of acquiring mining projects which demonstrate significant development upside, in jurisdictions with established infrastructure and mining codes, and where strong operational controls can be assured.

In addition to progressing its acquisition-led strategy, following the strategic review of its portfolio of projects in Mexico during 2018-19, the Company has identified exploration targets across its 12 mining concessions in Zacatecas, Mexico, which it is working to advance systematically.
