Silver projects

​San Celso

The San Celso project contains five high-grade veins with grades up to 395g/t Ag, 13,700ppm Pb, and 13,900ppm Zn. None of these veins appear to have been systematically drilled previously, to define a compliant resource.

Alien Metals' geochemical exploration work suggests the silver-lead-zinc mineralisation is indicative of a low sulphidation epithermal system, and initial observations of the vein systems indicate similarities to the Company’s previously owned and nearby San José mine, where historic mining exploited the San José vein down to approximately 300 metres. At San Celso, historic mining terminated at the water table (approximately 90 metres) and the Company believes there is considerable depth potential to both the San Celso and Las Cristinitas veins.

A schematic map of the area showing the various identified veins is set out below:

Los Campos project

The 500 hectare Los Campos project includes the former Los Campos mine, its satellite excavations, and, it is believed, two vein systems: the San Rafael vein and the Los Campos vein.

Arian Silver plans to rehabilitate several of the old mine shafts in this area to:

  • ascertain the extent of historic mine workings;
  • identify potential highly mineralised zones for follow-up drilling; and
  • undertake further mapping to verify the presence of additional vein structures

San Rafael vein system

Within the centre of the Los Campos concession is a large kaolin (clay) quarry which, until recently, has been active, extracting high quality kaolin. Clay alteration typically occurs immediately above or adjacent to high-grade mineralisation zones within epithermal deposits; this is therefore a very good indicator of where to focus further exploration.

In addition, outside of the project boundary to the north-west there are several large stopes reaching the surface, which is a strong indicator of the presence of high levels of mineralisation.

Los Campos vein system

The Los Campos vein system has been developed along a strike distance of approximately 3.3km and to depths exceeding 100m. Alien Metals' recent geological mapping and sampling has discovered previously unknown veins running either parallel or nearly parallel to the Los Campos vein.

La Africana project

The La Africana project is a “brownfield” site approximately 50 kilometres south of the State capital, Zacatecas, and comprises the small-scale and past-producing Africana Mine, and two known veins: the Africana vein and the El Sastre vein.

The Africana vein contains significant zones of high-grade silver mineralisation over respectable widths (up to approximately 5 metres).

Sampling at La Africana has delivered results of up to 824g/t Ag (grab samples) and 1,195g/t Ag (underground sampling). The existing underground workings have been surveyed it appears mining terminated at approximately 50 metres below surface, which coincides with the current water table. Evidence suggests that the mineralisation extends below this level.

No significant sampling has yet been undertaken on the El Sastre vein to date.

A future drill programme would be required to enable a compliant mineral resource to be delineated.

Navidad

The Navidad project is very prospective for epithermal-style mineralisation but is very early-stage and currently represents one of our least explored concessions.

It covers an area of approximately 100 hectares to the south of the town of Guadalupe, and to the south-west of Alien Metals' Africana, Donovan and San Celso projects, with good access to infrastructure.
