Los Andes Copper Ltd. (TSXV:LA) announced the final assay results from the current 2015-2016 diamond drill program.

Los Andes Copper Ltd. (TSXV:LA) announced the final assay results from the current 2015-2016 diamond drill program. These demonstrate that the higher grades identified near surface extend below the historical drilling and supports the new geological model.
As quoted in the press release:

Drill Hole V2015-08
The final assay results for the drill hole V2015-08 have been received. The results supports the new geological models showing the higher grades in the early diorite porphyry. Key intersects from the final hole include:

  • 502.0 m @ 0.631 % Cu, 209 ppm Mo and 1.3 g/t Ag from 130 m downholeIncluding:54.0 m @ 1.023 % Cu, 128 ppm Mo and 1.4 g/t Ag from 130 m downhole.396.3 m @ 0.566 % Cu, 233 ppm Mo and 1.2 g/t Ag from 235.8 m downhole.

This hole was drilled in the eastern part of the central core, 270 metres to the north of V2015-05. The aim of the hole was to show the depth extension of the mineralisation beneath the historical drill holes drilled in this area.
From a depth of 3.0 metres to a depth of 61.5 metres the hole intersected a post mineralisation dacite dyke. The drill hole then entered the andesite host rock that has been intruded by small tourmaline and hydrothermal breccias. The leached zone extended to 130.0 metres. From a depth of 130.0 metres, the drill hole intersected 502.0 metres @ 0.631 % Cu, 209 ppm Mo and 1.3 g/t Ag.
The upper part of drill hole was andesite host rock with strong stockwork and minor intervals of breccia with a post mineral dacite dyke from 184.0 metres to 198.8 metres. The mineralisation in this section was 54.0 metres @ 1.023 % Cu, 128 ppm Mo and 1.4 g/t Ag from 130.0 metres downhole depth and 37.0 metres @ 0.92 % Cu, 132 ppm Mo and 2.0 g/t Ag from a downhole depth of 198.8 metres. This high grade mineralisation is near surface and would be mined in the early years of any mine project.
At a depth of 235.8 metres the drill hole intersected the early diorite porphyry and intersected a total of 396.3 metres @ 0.566 % Cu, 233 ppm Mo and 1.2 g/t Ag. This intersection shows the importance identifying the early diorite porphyry and shows the good primary mineralisation in the central core of the project. From a depth of 632.0 metres to the end of drill hole at 725.5 metres the drill hole intersected tonalite porphyry which from 706.0 metres was cut by a hydrothermal breccia. The average grade over this section was 93.5 metres @ 0.362 % Cu, 566 ppm Mo, 0.7 g/t Ag and 0.511 % CuEq*. The substantially higher molybdenum values mean that the copper equivalent grade was 0.511 %.
This drill hole demonstrates the near surface higher grades in the supergene enriched andesite and the good grades that are associated with the early diorite porphyry. The drill hole confirmed the new geological model in this area demonstrating that the grades seen in the shorter historical drill holes extended to at least 700 metres below the surface.
