Rupert Resources Ltd., as previously announced, is carrying out a drilling and exploration campaign on the permitted Pahtavaara gold mine in Northern Finland, over which it has a six month purchase option.
"These are very encouraging exploration results in our first drill program on Pahtavaara. Rupert will continue developing its work programs and evaluation process dedicated to our goal of returning the Pahtavaara gold mine to production next year as a lower cost gold producer", said Brian Hinchcliffe, Rupert's President and CEO.
The Company is pleased to announce the results of assays back from the first three holes (507 m), including hole 116005, which contained visible gold and returned 32.74 grams per ton of gold ("g/t Au") over 5.0 meters ("m") at depths of 125 to 130 m, including 159.4 g/t Au over 1.0 m. The hole also contained 2.4 g/t Au over 9.0 m including 15.9 g/t Au over 1.0 m. These intersections are located at 125 m and 148 m below surface, respectively. These are the first three holes of a 3,000 m, 17 hole drilling campaign designed to test various areas in the Pahtavaara open pit and underground mine areas and to test "wildcat" targets as well. To date 17 holes have been drilled (2,630 m).
Drill Results
Results from this new drilling are as follows:
Hole ID 116005 (Karoliina- azimuth 201, dip -51.29, northing 7504900, easting 3474335, eln 252):
- 32.7 g/t Au over 5.0 m, including 159.4 g/t Au over 1.0 m, at 125 to 130 m; and
- 2.4 g/t Au over 9.0 m, including 15.9 g/t Au over 1.0 m, at 144 to 153 m.
Hole ID 116001 (Karoliina- azimuth 220, dip -74.6, northing 7504870, easting 3474375, eln 251.2):
- 1.7 g/t Au over 8.0 m, including 6.3 g/t Au over 1.0 m, at 211 to 219 m.
Hole ID 116002 (Karoliina- azimuth 194, dip -52.69, northing 7504870, easting 3474375, eln 251.2):
- 1.0 g/t Au over 5.0 m, at 111 to 116 m.
No upper cutoff grade was applied. True widths are unknown unless specified.
Results are reported for holes that primarily targeted the Karoliina zone which is the last new discovery on the Pahtavaara property, located on its western side and open. In hole 116005, the second zone is likely a splay structure of the primary Karoliina horizon.
These 116005 intersections are located 50 m above of previously-drilled hole 114809 that returned 8.1 g/t Au over 5.0 m, and 80 m above (and west of) hole 113810 that returned 4.6 g/t Au over 6.0 m. Hole 116001 is located 80 m below, and hole 116002 is located 45 m above (and east of), previously drilled hole 113810 which intersected 4.6 g/t Au over 6.0 m. The Karoliina Zone has been identified over a strike length of 550 m and to a depth of 400 m below surface. Where drilled, the zone only has been traced for 110 m, where it remains open.
Trenching
Excavator trenching started on July 19, 2016, with the focus on looking for extensions to existing pits/ finding new pit mineralization.
Mineralization
Intercepts reported above are hosted by amphibolitized komatiites. The principal geologic control in the area is a linear structural corridor that trends east-west, forms multiple folds, and dips steeply to the north on the south side and steeply south on the north side. The mineralized zone identified on Rupert's property is characterized by hydrothermal alteration and mineralization within various phases of pervasively altered komatiites. Mineralization remains open at depth along the entire Zone. The hydrothermal alteration and the Au-bearing veins associated with it are deformed. Because they were competent rocks (massive amphibole), they resisted deformation. They are therefore less deformed than the adjacent talc-chlorite schists. This implies early brittle deformation followed by ductile deformation. Hydrothermal fluids entered by fractures and faults, which explains why some alteration fronts are almost perpendicular to the schistosity.
The Pahtavaara gold deposit is hosted by the Sattasvaara komatiites. There are three major rock types that have been intercalated with one another; amphibole-chlorite schist, biotite schist and coarse-grained amphibole rocks with associated quartz-barite lenses, veins and irregular pods.
Talc-carbonate veins with pyrite are common in all lithologies, but particularly in the biotite schist. Amphibole chlorite schists are the dominant rock type outside the Pahtavaara alteration zone. They represent the regional greenschist facies metamorphic mineral assemblage and therefore correspond with the most typical and least altered rock type of the Sattasvaara komatiites.
Gold occurs mostly as free gold, a smaller part is associated with magnetite.
Review by Qualified Person, Quality Control and Reports
In compliance with National Instrument 43-101, Mr. Mike Sutton, P.Geo. is the Qualified Person responsible for the accuracy of the technical information in this news release. All samples are assayed by CRS/Actlabs Finland at Takatie 6, 90440 Kempele Finland, who have ISO9001 sample prep and an ISO17025 lab certification. All core is under watch from the drill site to the core processing facility. Samples are assayed with LeachWell for metallic screens. The Company's QA/QC program includes the regular insertion of blanks and standards into the sample shipments, as well as instructions for duplication. Standards, blanks and duplicates are inserted at one per 20 samples. Approximately five percent (5%) of the pulps and rejects are sent for check assaying at a second lab with the results averaged and intersections updated when received. Core recovery in the mineralized zones has averaged 99%.
