The Sleeping Giant occurrence is located on middle south-facing slopes of the Willian Creek Valley, about 26 kilometres southeast of Terrace.
The Midas property, which covers the Sleeping Giant showing, is underlain by Permian and older Mount Attree volcanics (Zymoetz Group) and Eocene Williams Creek pluton granodiorite. The volcanics consist of submarine volcanic rocks comprising greenstone, andesite-rhyolite tuff, and massive andesite. These are extensively altered and gossanous. The volcanics are weakly to intensely foliated, striking north-northwest and dipping 70 to 80 degrees east. A major fault, trending 010 degrees and dipping 80 to 90 degrees east, cuts the volcanics, and has associated mineralized shear zones and quartz veins. It has only been relatively recently (ca. 2007) established by the British Columbia Geological Survey mapping that Mount Attree rocks are of Paleozoic age and occur as part of the Paleozoic to Mesozoic Stikine assemblage of Stikinia. Stikinia’s Lower Jurassic Telkwa Formation andesites and rhyolites occur extensively east of the property. The property is on Stikinia’s western boundary with the Cretaceous to Tertiary age Coast Plutonic Complex.
In 2007, mapping by the British Columbia Geological Survey discovered mineralization and alteration consistent with a distal, Kuroko-type volcanic-hosted massive sulphide (VHMS) system within a package of highly altered Paleozoic volcanic rocks. Key to this discovery was the recognition of a group of Paleozoic submarine volcanic rocks, named the Mount Attree volcanics, which had previously been mapped as part of the Lower Jurassic Telkwa Formation. The Telkwa volcanic rocks are not considered prospective for VHMS deposits because they formed in a subaerial, compressional environment, whereas the Paleozoic volcanic rocks formed in a submarine setting and an extensional tectonic environment favourable to VHMS formation. Furthermore, the Paleozoic volcanic rocks are correlative with the Stikine assemblage which is host to multiple, significant VHMS deposits within British Columbia (Fieldwork 2007).
The Sleeping Giant zone was discovered in 2016 at a road cut approximately 5 kilometres northeast of the King Solomon Trend (Gazelle, 103I 185; Sub, 103I 240). Mineralization appears to be quartz veining hosted in silicified and clay altered andesitic volcanics. The best assay from a bedrock grab sample at the Sleeping Giant zone assayed 2.52 grams per tonne gold, 128 grams per tonne silver and 8.11 per cent copper. The sample (S023108) was from a 1 to 4 centimetre sheared copper-rich vein exhibiting strong clay alteration. Mineralization consists of pyrite, chalcopyrite, covellite, malachite and azurite (Assessment Report 36876).
In 2016, the Midas property was staked by J2 Syndicate Holdings Ltd. following a reconnaissance exploration program. Multiple property visits were conducted during the 2016 field season to follow-up on anomalous rock samples, and a total of 283 rock and 39 silt samples were taken. The Midas property covers the Gazelle (103I 185), VG (new MINFILE occurrence), Sub (103I 240), Copper Queen (103I 131), JLN (103I 231) and Sleeping Giant showings. In 2017, as part of the start of the 2017 exploration program at the Midas property, a 733 line-kilometre SkyTEM 312M aerial electromagnetic survey was flown on behalf of J2 Syndicate Holdings.
In 2017, as part of the start of the 2017 exploration program at the Midas property, a 733 line-kilometre SkyTEM 312M aerial electromagnetic survey was flown on behalf of J2 Syndicate Holdings (Assessment Report 36907). In 2018, J2 Syndicate Holdings Ltd. and Juggernaut Exploration Ltd. focused exploration efforts on the King Soloman Trend with LiDAR, Induced Polarization and rock sampling surveys followed by 16 holes (1977 metres) of NQ diamond drilling (Assessment Report 38320). In 2019, 9 more NQ holes were drilled in the the King Soloman Trend (Assessment Report 38961).
