Los Andes Announces Final Results of 2017 Drill Program at the Vizcachitas Deposit

Vancouver, British Columbia--(Newsfile Corp. - September 27, 2017) - Los Andes Copper Ltd. (TSXV: LA) ("Los Andes", or the "Company") is very pleased to announce the results of drill holes V2017-08, V2017-09B, V2017-10 and V2017-11. Following the results already published for the 2017 campaign, these results provide support to the extension to the north of the current central core, with some of the highest grade intersections in the deposit being encountered in V2017-10, the northernmost hole of this campaign. Results also provide further support to the continuity of higher grade mineralization near surface in the project's central core, over an area of 350 metres north-south by 400 metres east-west.

The key results from these holes are:

V2017-09B:

• 77.6 m @ 0.52 % Cu, 153 ppm Mo and 1.3 g/t Ag (0.57 % CuEq) from 64.4 m downhole
  
  Including:
  
  22.0 m @ 0.60 % Cu, 248 ppm Mo and 1.4 g/t Ag (0.68 % CuEq) from 108.0 m downhole

V2017-10:

• 506.0 m @ 0.57 % Cu, 357 ppm Mo and 1.1 g/t Ag (0.67 % CuEq) from 486.0 m downhole
  
  Including:
  
  76.0 m @ 0.69 % Cu, 522 ppm Mo and 1.5 g/t Ag (0.84 % CuEq) from 514.0 m downhole
  
  Including within, 30.0 m@ 0.95 % Cu, 337 ppm Mo and 1.6 g/t Ag (1.05 % CuEq) from 558.0 m downhole

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 V2017-08

V2017-08 was drilled in a northerly direction from the same platform as V2017?EUR'05. The aim of the drill hole was to test the covered area between the two outcropping un-mineralised diatreme breccias. The hole was speculative in that there are no nearby drill holes and no outcrop. If the drill hole showed that there was mineralised material between these two outcrops, this would have opened up a large area to the west. In the end, the hole encountered only diatreme indicating that the two outcrops are connected at depth.

Drill Hole V2017-09B

V2017-09B was drilled in a south-east direction from the same platform as the drill hole V2015-02. The hole was designed to test the southern extension of the mineralisation identified in drill holes V2015-03 and V2015-05. The top of bedrock was at a depth of 64.4 metres, where a sequence of andesites and hornfels continued to a depth of 570.9 metres. The drill hole then entered a tonalite until the end of the hole at a depth of 804.2 metres. From the top of bedrock, at a depth of 64.4 metres, the drill hole intersected 77.6 m @ 0.52 % Cu, 153 ppm Mo and 1.3 g/t Ag (0.57 % CuEq). This intersection demonstrates the southern continuity of the good supergene mineralisation identified in the drill holes to the north and further extends it to the south.

Key intersections from drill hole V2017-09B:

* 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 V2017-10

V2017-10 was drilled in a north-east direction to check the northern extension of the mineralisation that had been identified in the drill hole V2017-05. The top of bedrock was intersected at a depth of 50.5 metres. The drill hole cut a sequence of fine and medium grained diorites and occasional hydrothermal breccias to a depth of 486 metres. From a depth of 486 metres, the drill hole entered a long sequence of hydrothermal breccias, with 506 m @ 0.57 % Cu, 357 ppm Mo and 1.1 g/t Ag (0.67 % CuEq). Within this run there some higher grade sections with 30 m @ 0.95 % Cu, 337 ppm Mo and 1.6 g/t Ag (1.05 % CuEq) from 558 metre downhole and also 88 m @ 0.70 % Cu, 278 ppm Mo and 1.4 g/t Ag (0.78 % CuEq) from 684 metre downhole.

The grades improve with depth as the chalcopyrite-pyrite ratio increases and, from a depth of 920 metres, bornite was identified in drill hole with up to 20 percent of the sulphides being bornite. This mineralisation shows the potential for the grade to increase with depth.

This good mineralisation is open to the north. This drill hole and V2017-05 have transformed the northern part of the project, with high grade mineralisation within the hydrothermal breccias and the early diorite porphyry. In the 2014 PEA, this area was classified as waste.

Key intersections from drill hole V2017-10:

* 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 V2017-11

V2017-11 was drilled 150 metres to the south of V2017-10, to find the southern extension of the mineralisation identified in drill holes: V2017-05 and V2017-10. This hole was also intended to check the northern extensions of the mineralisation identified in V2015-01 and V2015-08.The top of bedrock was intersected at a depth of 86 metres in a fine grained diorite which continued to a depth of 632 metres. Within this run there some higher grade sections with 26 m @ 0.55 % Cu, 253 ppm Mo and 1.2 g/t Ag (0.63 % CuEq) from 488.0 metre downhole. From a depth of 600 metres, bornite mineralisation was identified with up to 10 percent of the sulphides being bornite. The bornite mineralisation, like in drill hole V2017-10, demonstrates the potential for increasing grades with depth. From a depth of 632 metres, the drill hole entered a post mineral dacite dyke and diatreme.

Key intersections from drill hole V2017-11:

* 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.
