Alien Metals Limited (“Alien Metals” or “Company”), the exploration and development company, is pleased to announce results of the recent sampling programmes on the San Celso and Los Campos silver projects in Mexico. The results show strong correlation with historic results, increasing confidence in future drilling programmes to be undertaken at San Celso and Los Campos. The Company has also signed final legal documentation to allow it to carry out exploration work with an option to acquire the Nueva Andromeda permit located contiguous to the east of the San Celso project area. Both of these events tie into the long-term development plans for these projects.


  • Sampling programme results show excellent correlation with historic sampling
  • Continued high-grade results across both projects
  • Added detail for maiden drill campaign planning
  • Option agreement signed for acquisition of highly prospective Nueva Andromeda permit adjacent to the San Celso project, expanding project footprint and mineralisation potential (increasing strike length to nearly 3000 metres (‘m’))
    • Permit hosts a continuation of the Andromeda vein, which runs into the San Celso project
    • Andromeda vein has been mapped with historical workings for over 500m

Bill Brodie Good, Chief Executive Officer, commented:

“We are pleased to have completed further underground and surface sampling at San Celso and Los Campos. In total, 12 samples were collected across the projects as well as some surface reconnaissance on neighbouring ground on strike south of the San Celso project area with signs of further historic mining. The results further validate the high-grade underground grades; the continuity away from the historic workings encourages us to push ahead with the next stage drilling work. Recent heavy rains and underground conditions limited the extent of the sampling programmes, however we are looking forward to getting back on the ground in the near-term.

“With the acquisition of the Nueva Andromeda permit, we will enhance the potential of the San Celso project. We believe the combined project area hosts the potential to be a sizeable, high-grade silver project, and we are looking forward to being able to do further mapping and sampling over the Andromeda vein prior to the next stage of drilling.”

San Celso (Silver)

Located within the Zacatecas Silver belt of Mexico, the San Celso project is 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.

Having located recently the details of the 2006 underground sampling undertaken on the San Celso and Las Cristinitas historic mines, the Company was given significant encouragement for the project as they highlight the continuous high-grade nature of the historic workings and show that the mineralisation continues on strike and down dip within the historic mined areas. In 2006, the Company (as Arian Silver) collected a total of 438 samples from the San Celso and Las Cristinitas underground workings and surface dumps, and the three levels were accessible in the San Celso mine by approximately 130m of ladder. Of these, 265 chip-channel samples were from the Las Cristinitas workings. Assay results included a 4.65m interval at >1000 grams per tonne (‘g/t’) silver (‘Ag’) including 1.05m at 2,683 g/t Ag, 78.2 ounce per tonne (‘Oz/t’) Ag with an average of 460 g/t Ag from 60 samples > 200 g/t Ag from the La Cristinitas vein and an average of 497 g/t Ag from 77 samples > 200 G/t Ag from the San Celso vein.


The recent follow up underground sampling programme was designed to confirm previous sampling as well as infill certain gaps to get a complete picture and understanding of the main mineralisation. Four samples were taken underground from the San Celso historic mine area, at the 2,132m level.

The new assay results support the historic sampling with sample suite SC066 returning composite 0.9m at 477 g/t Ag (including sample SC066B that returned 950 g/t Ag from a 30 cm channel sample) compared to the 2006 sample result of 0.5m at 422 g/t Ag, while sample suite SC062 returned composite 1.4m at 225 g/t Ag compared to the 2006 sample results of 1.6m at 335 g/t Ag. The samples were taken as close to the originals as possible and confirm to Alien the high grade and economic widths of the Las Cristinitas vein.

Surface reconnaissance was undertaken to the south east of the San Celso project boundary, which revealed more historic workings and continued high grade silver potential along strike. Alien is in the process of applying for the surrounding vacant areas.

Los Campos (Silver)

Located within the Zacatecas Silver belt of Mexico, previous exploration activity at Los Campos highlighted the high-grade silver potential of the project, which features a historic mine within the project area which records show was mined between 1883 until all work stopped in 1904. The mine achieved an average mine head grade of over 1,000 g/t Ag (32.2 oz/t Ag) in the early 1890s. The project is also situated adjacent to Endeavour Mining’s (TSX:EDV) El Compas operating silver-gold mine.


As at the San Celso project, Alien was keen to access and sample part of the historic underground mine to add knowledge and understanding of the mineralised systems to better plan and target a future drilling campaign.

The Company’s exploration team attempted to access the underground workings at Los Campos, however they were unable to safely access historic adits due to recent torrential rain and unstable entry points. Alien intends to revisit the Los Campos project in the coming months to refurbish entry areas.

Further surface sampling and review work was carried out in the central southern area of the project, along the surface from historical workings. This returned some further excellent results associated with the main north-west/south-east trending workings, with a maximum result of 361 g/t Ag. These results support previous sampling and add further encouragement for the next stage of exploration and upcoming maiden drilling programme. Samples from smaller vein systems striking oblique to the main system returned background results helping to focus next stage onto the core known defined mineralised veins already identified.

Table 1 below summarises all results from the recent sampling programme for both project areas. Due to the number of samples submitted and the reconnaissance focused nature of the programme, Alien did not insert any standard or blank samples into the sample batch. The in-house sample QA/QC completed by ALS was deemed acceptable for the purposes of this work. All samples were analysed by Aqua Regia Digest with ICP finish for Au for 35 elements at ALS Zacatecas, Mexico.

Alien is now focussed on finalising necessary permitting to carry out maiden drill programmes on both projects as soon as possible.

Alien has signed an option agreement with the holders of the Nueva Andromeda permit, which is contiguous to the San Celso project. This agreement will give Alien exclusive exploration and mining rights within the tenement for a period of three years for a minimal annual fee (3,000 USD) with an option to buy the rights to the property at the end of the three-year period.

The Nueva Andromeda tenement is a significant addition to the San Celso project as it contains the main strike length of the mineralised Andromeda vein, which has already been identified in the current project area. From previous field work Alien has already noted further historic mining along this vein. The acquisition of Nueva Andromeda will increase the high grade silver mineralised strike length from 2,500m to at least 3,000m, therefore Alien believes that this addition will greatly enhance the economic prospectivity of the project.

Further adjacent vacant ground around the San Celso project is also being applied for directly by Alien through the normal processes at the Ministry of Mines in Mexico and updates will be provided as news becomes available.

Alien is also continuing discussions with a range of parties regarding potential joint venture opportunities; however, no binding agreements have been reached to date.
