Aura Silver Resources Inc. is pleased to report that drilling for 2017 has been completed on our Greyhound property located in Nunavut, Canada. Agnico Eagle Mines Limited carried out the program to follow up on 2015/16 drill results.
Work included prospecting in new areas and diamond drilling of ten holes for a total of 2,262 metres. Assays have been recorded for all holes and recent results are being interpreted by Agnico Eagle, to be reported to Aura Silver during November along with future exploration plans. Approximately 70 assays for samples collected during an August prospecting survey over new areas are not yet received.
Two high-priority areas now stand out for further exploration: (i) Aura Lake, where high grade boulders up to one ounce/ton are located at surface with gold infused-quartz veins intersected in drilling nearby; and (ii) Dingo West, where a kilometer-long quartz vein, with noted gold in assay grab samples, outcrops and lies adjacent to an untested copper gossan. Both areas show deformation, hydrothermal activity and very large alteration halos in the enclosing volcanic rocks.
As reported previously the best drill hole in 2015 intersected 6.41 g/t Au over 1.5 metres at the bottom of hole GHD15-017. A check assay of this interval confirmed an increase of grade to 7.4 g/t Au. Follow up hole GHD17-021 was drilled in the close proximity to hole GHD15-017 (but much deeper; 384 metres in core length). In this hole 8 different traces of visible gold were identified over a core length of 3.0 metres (336-339m) however the best one metre interval assayed 0.536 g/t Au.

Holes GHD17-024 and 25 tested the same target but failed to intersect additional quartz veins so it has been interpreted that the gold at this location is an isolated occurrence.
Closer to the south end of Aura Lake where prospecting uncovered surface samples containing gold up to one ounce per ton, hole GHD17-023 targeted a magnetically interpreted structural target and intersected quartz veining assaying 3.3 g/t Au over a core length of 3.0 metres (from 94-97m) which included a shorter interval of 1.8 metres assaying 5.42 g/t Au. Deeper in the hole were several hits of gold mineralization: from 100-109.5 metres assaying from 0.2 to 0.45 g/t Au; at 138 metres 1.38 g/t Au over 1.5 metres; and, at 179.3 metres 0.993 g/t Au over 1.7 metres. Shorter holes were drilled on either side of GHD17-023 which both intersected similar quartz veins suggesting that the mineralization in GHD17-023 was not isolated but may form part of a quartz vein system within a large siliceous, pyritic, sericite alteration zone. Hole GHD17-026 hit 1.202 g/t Au over 3.6 metres (62.2-65.8m) including 0.8 metres of 4.92 g/t Au at 63.5 metres. Hole GHD17-027 intersected 0.197 g/t Au from 38.2-41.3 metres (3.1 m) and 0.94 g/t Au at 42.1 metres. Although the grades were not spectacular it is the first time in a drill program on the property that continuity of mineralization has been established. Further follow-up will be required to fully evaluate these interesting gold intercepts in quartz veins.
In the northeastern portion of the claim group, a long, linear quartz vein was traced over 1.7 kilometres in strike length. Grab samples collected from this vein, referred to as the Dingo Zone, assayed from 1.18 g/t Au up to 126 g/t Au and 96.6 to 356 g/t Ag. West of this vein a gossanous copper rich stringer zone assayed 0.896 g/t Au in one grab sample. The copper gossan zone target has not been drill tested and further I.P. geophysical surveys, prospecting and diamond drilling are recommended.
Bob Boaz, CEO states, “We are very pleased with the latest round of drill results as for the first time drilling has intersected gold mineralization that appears to be continuous over several holes rather than an isolated drill intercept. Both structural and alteration features are present in the area of south Aura Lake as are the high-grade boulders. The Company expects that exploration will stay focused on this area in 2018.”
Agnico Eagle Completes First Phase of Option Agreement
Agnico Eagle has completed phase one of the option agreement to acquire a 51% interest in Aura Silver’s Greyhound property in Nunavut, Canada. This included completion of the $1,750,000 expenditure requirement at the end of May 2017 as well as option payments to Aura Silver totaling $210,000. Aura Silver is now in discussions with Agnico Eagle to plan the 2018 Greyhound drill program.
