Los Andes Copper Ltd. (TSXV:LA) announced the results from the first four drill holes of the 2015-2016 diamond drill program. The assay results from these drill holes confirm the presence of higher grade mineralization in the project’s central core.
As quoted in the press release:

Historical drilling was carried out on the Vizcachitas project in three campaigns during 1993, 1996/1997 and 2007/2008. However, the higher grade central core had only been drilled in the 1990’s campaigns and with generally shallower drill holes, therefore not properly reflecting the potential of this core area.
Los Andes has begun a drill program to confirm a new geological model and to demonstrate the extent of the central core mineralisation. A first stage of this campaign has been drilled, with eight diamond drill holes totaling 3,661 metres.
Highlights from these four drill holes are:

  • The results confirm the new geological model showing how the central higher grade core extends over an area of at least 700 metres north-south and 700 metres east-west.
  • The project is still open to the east, west, north and at depth.
  • The presence of silver mineralisation in the range of 0.8 g/t to 2 g/t is confirmed.

The drilling intersected long sequences of greater than 0.6 % Cu with significant Mo and Ag credits.


The current drill hole program was designed to test this geological model and confirm the extent of the higher grade central core.As part of the preparatory work for this drilling campaign, the Los Andes geologists re-logged all of the 146 drill holes located within the property. The re-logging was led by Gonzalo Saldias, a geologist well recognised in Chilean porphyry systems. This detailed review showed that the historical logging and geological model had not properly identified the importance of the higher grade early dioritic porphyry and hydrothermal breccias. The recent logging showed that these higher grade geological units extend over distance of 1,400 metres north-south and 700 metres east-west. The mapping shows that these breccias have grades increasing with depth and demonstrate the potential for higher grades at depth.
