Los Campos

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.

Alien Metals 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.
