Background

Historical drilling was carried out on the Vizcachitas project in three exploration 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.

During 2014, a complete review of the historical information was performed to better understand the project, including re-logging all of the 146 drill holes located within the property. The re-logging was led by Gonzalo Saldias, a Chilean geologist and one of the most recognized experts 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 diorite porphyry and hydrothermal breccias. The re-logging showed that these higher grade geological units extend over a distance of 1,400 metres north-south and 700 metres east-west. The mapping showed that these breccias have grades increasing with depth and demonstrates the potential for higher grades below the historical drilling.

In 2015, Los Andes began a drill program to confirm a new geological model and to demonstrate the extent of the central core mineralisation. A first stage of this exploration campaign was completed in 2015/2016, with eight diamond drill holes totaling 3,661 metres. During 2017, Los Andes has carried out a second stage of this campaign with the purpose of demonstrating the northern and southern extension of the high grade core.

Summary of Drill Holes

Drill Hole V2017-06

V2017-06 was drilled in a south east direction underneath the drill holes V2015‑08 which was drilled in a north-easterly direction. The aim of the drill hole was to confirm the good mineralisation identified in this drill hole and then to test the eastward extension of this mineralisation.

The top of bedrock was intersected at a depth of 15 metres and the drill hole continued through andesite and hydrothermal breccias to a depth of 802 metres when it intersected a tonalitic intrusive. The drill hole was stopped at a depth of 857.0 metres. From a downhole depth of 64 metres, the drill hole intersected 440 metre @ 0.51 % Cu, 164 ppm Mo and 1.1 g/t Ag (0.56 % CuEq) in andesites. This includes from a downhole depth of 76 metres, 56 metres @ 0.81 % Cu, 72 ppm Mo and 1.6 g/t Ag (0.85 % CuEq). This intersection confirms the near surface mineralisation identified within this eastern block. The mineralisation continues until the drill hole intersected the intermineral tonalite intrusive at a depth of 802 metres. Some of the better mineralisation is shown in the table below.

Key intersections from drill hole V2017-06:

* Copper equivalent grade has been calculated using the following expression: Cu Eq (%) = CuT (%) + 2.5 x Mo (%) + 110.55 x Ag (%), using the metal prices: $ 2.2 / lb. Cu, $5.5 / lb. Mo and $15.2 / Oz (same reference prices as in reporting of 2015/2016 results). All thicknesses from intersections from drill holes are down-hole drilled thicknesses. True widths cannot be determined from the information available.

Drill Hole V2017-07

V2017-07 was drilled in a south east direction underneath the drill holes V2015‑05 and V2017-02 which were drilled in a north-easterly direction. The aim of the drill hole was to confirm the good mineralisation identified in these drill holes and then to test the eastward extension of this mineralisation.

The top of bedrock was intersected at a depth of 33 metre and the drill hole continued through andesite and hydrothermal breccias to final depth of 721 metres. From a downhole depth of 44 metres, the drill hole intersected 102 metres @ 0.62 % Cu, 157 ppm Mo and 1.5 g/t Ag (0.66 % CuEq) in andesites. This intersection further confirms the horizontal extension of the near surface supergene mineralisation over an area of 350 metres north-south by 400 metres east-west within this block. The mineralisation continues to a downhole depth of 344 metros with an average grade over 300 metres of 0.48 % Cu, 135 ppm Mo and 1.2 g/t Ag (0.53 % CuEq). The mineralisation below this depth decreases as the drill hole intersected andesites and a post mineral dacite dyke.

Key intersections from drill hole V2017-07:

* Copper equivalent grade has been calculated using the following expression: Cu Eq (%) = CuT (%) + 2.5 x Mo (%) + 110.55 x Ag (%), using the metal prices: $ 2.2 / lb. Cu, $5.5 / lb. Mo and $15.2 / Oz (same reference prices as in reporting of 2015/2016 results). All thicknesses from intersections from drill holes are down-hole drilled thicknesses. True widths cannot be determined from the information available.

QA/QC

Quality assurance and quality control procedures include the systematic insertion of duplicate and standard samples in to the sample stream. Drill core samples were sawn in half, labelled, placed in sealed bags and were shipped directly to the preparatory laboratory of ALS Minerals in Coquimbo, Chile. All geochemical analyses were performed by ALS Minerals in Lima Peru. All samples were assayed using the method ME-MS61, a four-acid digestion with an ICP-MS finish. Copper samples with grades above 0.6 % Cu were reanalysed using ALS method Cu-OG62, a four-acid digestion with an AAS finish.
