Alien Metals Limited (LON:UFO) High-grade Silver at San Celso and Los Campos projects

Further high-grade Silver Results at San Celso and Los Campos projects with up to 1,275 g/t Silver at San Celso and 547 g/t Silver at Los Campos, Mexico

Gold results of up to 2.68g/t Gold from Donovan 2 project

Alien Metals Ltd, the AIM quoted mineral exploration and development company, is pleased to announce the results of the July 2019 fieldwork carried out at the Company’s wholly owned Donovan 2, Los Campos and San Celso concessions in Zacatecas State, Mexico.

Highlights

  • Highly anomalous silver mineralisation at San Celso and Los Campos, confirmed
  • Significant further high-grade silver results returned from San Celso, including:
    • Maximum assay of 1,275 g/t silver (Ag)
    • 18 anomalous samples returning an average of 272 g/t Ag
  • Significant further high-grade silver results returned from Los Campos, including:
    • Maximum assay of 547 g/t Ag
    • 14 anomalous samples returning an average of 185 g/t Ag
  • Further gold identified at Donovan 2, including a sample returning 2.68 g/t gold (Au)
  • Company continues to assess a range of opportunities to advance Mexican projects, including via joint-venture

Bill Brodie Good, Technical Director of Alien commented, “the Company’s San Celso and Los Campos projects continue to show significant potential for high-grade silver mineralisation. This recent round of sampling has confirmed historic surface and underground work on these projects and that there remain significant mineralised in-situ ore bodies to be developed.”

As announced on 6 August 2019, Alien carried out a ground mapping and sampling program across the Company’s wholly owned Donovan 2, Los Campos and San Celso concessions in Zacatecas State, Mexico. The sampling programme was undertaken to follow up on previous work which had identified continued anomalous silver mineralisation at Los Campos and San Celso, and gold/copper mineralisation at Donovan 2. In particular, the sampling has confirmed the mineralisation controls that warrant follow up, as well as strengthening the Company’s understanding for next stage of exploration.

Donovan 2 (Gold, Copper)

The mapping and sampling programme at Donovan 2 focused on the south-western area of the project area to follow up the anomalous gold sample taken in May 2019.

Sample 7037, in the south western area of the project, returned 2.68 g/t Au and 46 g/t Ag from a silicified and veined Rhyolite float sample. Samples 7042 and 7038 returned 0.24 g/t and 0.23 g/t Au, respectively. The remaining samples at Donovan 2 returned background results for gold from this programme, highlighting that there is gold mineralisation within this area and justifying more detailed follow up work in this area. These samples are all situated over the ground magnetic anomaly in this area and further indicate the presence of anomalous gold mineralisation associated with this target.

Los Campos (Silver)

Previous exploration activity at Los Campos highlighted the high-grade silver potential of the Los Campos project, which features a historic mine within the project area which records seen by Alien show was mined between 1883 until all work stopped in 1904 with average mine head grade of over 1,000 g/t Ag in the early 1890s.

The programme was designed to further develop the Company’s knowledge and understanding of the mineralisation trends at Los Campos along strike from the know mineralised veins historically mined and mapped, and to aid in next-step planning.

The results of the sampling programme show that the mineralisation is concentrated in the previously defined main veins with further evidence that the historic dumps on the site contain some high-grade material (see table 1 below).

14 of the 50 samples taken were anomalous for silver returning an average of 185 g/t Ag, ranging from 43.6 g/t to 547 g/t Ag. 10 of these samples were from dumps around the shafts and confirm the high grade of the target veins mined historically and the fact that there remains high grade ore in the old workings as well. A sample taken from an outcrop returned 59.3 g/t Ag from an oxidised and veined tuff.

Overall the mineralisation appears focused in the historic ore body defined by the main veins, which was mined intermittently from 1883 to 1904. There is also further evidence that the historic dumps at the project contain some high-grade silver.

The excised area containing a clay quarry within the Los Campos tenements appears to contain one of the 2 main veins, with historic reports and photos recording that the San Rafael Vein system as running through this tenement. The presence of this kaolin body potentially indicates a zone of extreme weathering, possibly associated with mineralisation formation in the area. The San Rafael vein extends for over 200m within the excised tenement.

The interpreted location of the San Rafael Vein at Los Campos is set out here:

Based on the recent results and historic data, the mineralisation appears confined to the two main veins. With the historic mining and mapping work the vein locations are well defined. An initial scout drilling programme would help to test the depth and strike extension of these systems as well as the grade potential.

San Celso (Silver)

Located within the Zacatecas Silver belt of Mexico as well, the San Celso project remains a highly prospective silver target in a favourable mineralised district. Previous exploration programmes at San Celso have highlighted the high-grade silver potential of the project.

Recent surface mapping and sampling was undertaken to corroborate earlier reconnaissance and mapping of the area, and specifically to consolidate the historic sampling and mapping data and bring it up to date and merge with older data. The results confirm the very high grade of the known veins both in-situ as well as in surface dumps.

14 of the 39 samples taken were anomalous for silver returning an average of 276g/t Ag, ranging from 40.3 g/t Ag to 1,295g/t Ag. Eight of these samples were from dumps around the shafts and confirm the high grade of the target veins mined historically and the fact that there remains high grade ore in the old workings as well. Five of the samples were float samples, including the sample which returned 1,295g/t Ag

A sample taken from an outcrop returned 59.3 g/t Ag from an oxidised and veined tuff.

The results of this programme confirm the mineralisation source and add information to the potential of each of the Donovan 2, San Celso and Los Campos projects, as well as further supporting the reliability of historic exploration and sampling.

The Company plans to follow up targets identified at Donovan 2 in particular, with future programmes, including additional induced polarity (IP) and/or scout drilling and using these results combined with historic results and data in the context of the historical mines and their potential for redevelopment.

Alien is working towards reopening discussions with a range of parties following this work regarding potential joint venture opportunities.

Alien’s geological team continues to assess a range of mineral projects and opportunities, with particular focus on exploration projects with near-term news-flow and value creation.
