The Sparky zone area is underlain by rocks of the Lower Jurassic Unuk River Formation (Hazelton Group). Rocks in the area consist of volcanic breccia and andesite tuff, with interbedded siltstone, argillite and conglomerate. The area lies within the Portland Canal dike swarm, which consists generally of granodiorite/quartz diorite dikes.

The Sparky area was discovered through prospecting in 2008. The mineralization here is hosted in strongly silicified andesitic volcanics cut by abundant dikes of the Portland Canal dike swarm. The swarm is a dense package of east west striking south dipping andesite, dacite and rhyolite dikes. To the northwest the Sparky veins are cut by a younger, east-west trending granodiorite dike (that has followed the Sparky North Fault. Approximately 150 meters south of this dike there is another east-west structure (Sparky South Fault) that has been filled by a quartz porphyry dike. Between these two bodies there are several northwest striking younger dikes that have a similar northeast strike as the Sparky veins. It is believed that right lateral wrench movements along the two east-west trending Sparky Faults resulted in northwest en echelon structures that controlled both the mineralized veins and some of the later dikes.

Surface examination in 2008 revealed veins up to 1.5 metres thick that contains pods of massive pyrite and silver-sulfosalts. Elsewhere one zone of strong silicification with hydrothermal breccia cemented with vuggy silica which contain some pyrite-galena and possible tetrahedrite mineralization.

It was reported that examination of 2008 drilling revealed that the style of mineralization at the Sparky typically lacked the strong sphalerite and galena seen commonly across the property. The high grade 2.0 metres drill intersection from was hosted in moderately silicified grey green andesite with moderate quartz stockwork and 2-5 per cent disseminated pyrite. Several patches of visible gold are seen over a 4-centimetre width, associated with quartz stockwork veinlets. There were no sulphides other than pyrite associated with the gold.

Drilling to 2011 has indicated that at the Sparky zone there are several small flat lying mineralized zones plus one larger zone interpreted across the zone, including discontinuous quartz breccia bodies, and is still open to the north. Most holes are well mineralized and contain higher than usual silver values, although gold results appeared to decrease to the south.

WORK HISTORY

In 2008, Ascot drilled 3 holes in order to test the Sparky zone. Hole HL08-39 intersected a 2-metre-wide section grading 71.52 grams per tonne gold and 80.9 grams per tonne silver (Assessment Report 31000). Also at this time, sampling of a trench (T08-52) located on the Sparky zone yielded 1.92 gram per tonne gold, 687.8 grams per tonne silver, 0.44 per cent lead and 0.80 per cent zinc over 4.00 metres, while sampling of trenches (T08-53 and -54) located on the Bee zone to the north west yielded 1.16 and 1.00 grams per tonne gold with 279.9 and 371.6 grams per tonne silver over 8.00 and 5.00 metres, respectively (Christopher, P.A. (2009-08-03): Technical Report on the Premier Gold Project).

In 2010, six fan holes were drilled from three setups spaced approximately 100 metres apart along an east west line, all drilled to the north. Several steeply south-dipping mineralized zones were identified (Assessment Report 32357).

In 2011, Ascot Resources drilled a series of six holes along a north-south line. While drilling in 2010 concentrated on extending the zone east-west, the 2011 program used 6 drill holes to test for the north-south extension of a blind quartz breccia body. All holes were successful and indicate the zone has a gentle northerly dip and extends almost 300 metres north-south with the zone open to the north. Results from the most southern drill hole, P11-110, were lower but still contain gold mineralization, grading 0.27 gram per tonne gold over 17.50 metres, plus short intervals of siliceous breccia indicating the system may continue to the south (Assessment Report 33267). The main part of the system contains some large intervals grading 1.95 grams per tonne gold and 22.4 grams per tonne silver over 123.37 metres in P11-213, which includes 8.15 grams per tonne gold and 68.5 grams per tonne silver over 6.89 metres at 111.0 metres and also 73.0 grams per tonne gold and 34.8 grams per tonne silver over 2.0 metres at 159.0 metres (Assessment Report 33267). Silver results are higher at Sparky than observed elsewhere during the exploration program and may represent zonation along strike.

In 2012, diamond drilling on the Sparky zone yielded intercepts including 1.15 grams per tonne gold and 50.1 grams per tonne silver over 20.85 metres, including 3550 grams per tonne gold and 2180 grams per tonne silver over 0.45 metre in hole PR-12-391 (Puritch, E. (2013-03-27): Technical Report and Resource Estimate for the Big Missouri and Martha Ellen Deposits, Premier Gold Property).
