Los Andes (TSXV: $LA.V) Announces the Second Batch of Results for the 2017 Drill Program at the Vizcachitas Deposit

Results of Drill Hole V2017-02 Continue to Support Presence of Higher Grades in the Central Core Including an 88-metre Intersection of 0.60% Cu (0.72% Cueq)

 

Vancouver, British Columbia - August 9, 2017 (Newsfile Corp.) (Investorideas.com Newswire) Los Andes Copper Ltd. (TSXV: LA) ("Los Andes", or the "Company"), is very pleased to announce the results of the bottom portion of drill hole V2017-01A and all of V2017-02. Following the initial results published on June 30, 2017, these results further confirm the presence of higher grade mineralization in the project's central core.

The key results from the drill hole V2017-02 are:

As reported on June 30, 2017, drill hole V2015-01A demonstrated the continuity of the higher grade mineralization intersected during the successful 2015/2016 drilling campaign. Hole V2015-01A is 150 metres to the north of drill holes V2015-03 and V2015-05.

Drill hole V2017-02 is located on the same section as drill hole V2015-05 and V2015-03 and is 100 metres south of section for V2017-01A. The hole was drilled in a northwestern direction at an inclination of -65 degrees so that the hole is approximately 200 metres below drill hole V2015-05 on the section.

The drill hole has demonstrated the continuity of grade between the drill holes and the importance of the early diorite porphyry in the mineralisation of the deposit. The drilling results to date now demonstrate the continuity of the higher grade early diorite porphyry over a strike length of 200 metres from drill hole V2017-02 to V2015-08.

Cautionary Statement: All thicknesses from intersections from drill holes are down-hole drilled thicknesses. True widths cannot be determined from the information available.

Background

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.

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 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 V2017-01A

This hole was drilled on the southwestern part of the central core with a southeastern direction. The drill hole is 150 metres north the 2015 drill holes V2015-03 and V2015-05. The drill hole is also 100 metres south of the 2015 drill hole V2015-08.

The top of bedrock was intersected at 71.9 metres in diorite porphyry with disseminated chalcopyrite which continued to a depth of 238.0 metres. Within this sequence there was secondary enrichment from 134 to 162 metres where the average grade was 0.61 % Cu, 42 ppm Mo and 1.6 g/t Ag. At a depth of 238 metres the rock type changed to medium grained diorite and continued to a depth of 513.15 metres. Within this sequence there is a well mineralised sequence running from 226 metres to 360 with 0.60 % Cu, 150 ppm and 1.5 g/t Ag. From a depth of 513.15 to the end of the drill hole at depth of 851.25 metres the drill hole is primarily in igneous breccias and hydrothermal breccias.

This drill hole has demonstrated the continuity of the mineralisation between the drill holes 2015/2016 drill holes to the north and south. This near surface mineralisation would be mined during the first few years of an operating mine. It also shows the high primary grades within the medium grained diorites. These early phase diorites consistently have grades above 0.5 % Cu and are the target of this drilling campaign.

Key intersections from drill hole V2017-01A:

Key intersections from drill hole V2017-01A:

* 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 V2017-02

Drill hole V2017-02 is located on the same section as drill hole V2015-05 and V2015-03 and is 100 metres to the south of section for V2017-01A. The hole was drilled in a northwestern direction at an inclination of -65 degrees so that the hole is approximately 200 metres below drill hole V2015-05 on the section. The hole was drilled to test the vertical extent of the mineralisation identified in V2015-05 and the north-south strike length of the early diorite porphyry intersected in V2015-08.

The top of bedrock was intersected at a depth of 63 metres in a hydrothermal breccia with a high pyrite to chalcopyrite ratio. At a depth of 138 metres a well mineralised andesite was intersected. The assay results for the top of this unit are from a depth of 138 metres 0.53 % Cu, 103 ppm Mo and 1.0 g/t Ag (0.57 % CuEq) over a length of 22 metres.

From depth of 205 metres the drill hole intersected a long sequence of andesites and hydrothermal breccias down to a depth of 428 metres. This demonstrates the vertical extent of a similar sequence of rock types intersected in the drill hole V2015-05. The significant assay results within this sequence are shown in the table below.

At a depth of 683 metres the drill hole intersected the early diorite porphyry as proposed by the updated geological model. This early diorite porphyry had assay results from a depth of 680 metres of 0.60 % Cu, 389 ppm Mo, 1.5 g/t Ag (0.72 % CuEq) over a length of 88 metres. This further demonstrates the importance of this early stage porphyry unit in mineralisation of the deposit and confirms the north-south continuity from the drill hole V2015-08 200 metres to the north.

The drill hole then continued in a sequence of later stage tonalities, granodiorites and diorites to a final depth of 1030.6 metres.

Key intersections from drill hole V2017-02:

* 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.
