The Bluebird 2 occurrence is located on a ridge north of Merry Widow Creek, approximately 1 kilometre south-southeast of Newt Lake.
Regionally, the area is underlain by basaltic volcanic rocks of the Upper Triassic Karmutsen Formation (Vancouver Group), which are overlain sequentially by limestone of the Upper Triassic Quatsino Formation (Vancouver Group), limestone, mudstone and siltstone of the Upper Triassic Parson Bay Formation (Bonanza Group) and mixed volcanic and sedimentary rocks of the Lower Jurassic LeMare Lake volcanic unit (Bonanza Group). The volcanic and sedimentary rocks have been intruded by diabase and basaltic intrusive rocks of the Upper Triassic to Lower Jurassic Bonanza Group to the north and gabbro to quartz diorite of the Lower to Middle Jurassic Island Plutonic Suite to the west.
The occurrence consists of an irregular lens of massive sulphides that probably represents a small manto. The lens is between 0.3 and 1.5 metres wide and contains abundant pyrrhotite with lesser magnetite, chalcopyrite, black sphalerite, arsenopyrite and trace gold and cobaltite. Within the massive sulphides are small quantities of carbonate, epidote, garnet and chlorite.
The sulphide lens is gently dipping and is underlain by bleached, massive Quatsino Formation limestone of the Upper Triassic Vancouver Group. Overlying the sulphide lens are poorly exposed mafic rocks that could be either thinly-bedded tuffs of the Lower Jurassic Bonanza Group or an altered greenstone sill of the Jurassic Keystone Suite (Open File 1991-8).
In 2007, rock sampling, along a 30 metre mineralized outcrop, yielded values up to 7.78 grams per tonne gold, 14.1 grams per tonne silver, 0.123 per cent cobalt, 0.6 per cent copper, 0.153 per cent zinc and 40.4 per cent iron (Assessment Report 30002).
In 2020, a channel sample yielded 3.17 grams per tonne gold, 5.3 grams per tonne silver and 0.22 per cent copper over 2.0 metres (Assessment Report 39420).
Work History
The area has been explored in conjunction with the Merry Widow (MINFILE 092L 044) deposits since the early 1900’s. In 1968, Quatsino Copper Gold completed a program of airborne magnetic and radiometric geophysical surveys on the area. In 1970, Alice Lake Minerals completed an aeromagnetic survey. During 1989, through 1992, Taywin Resources completed programs of geological mapping, trenching and surface sampling on the area. During 2005 through 2012, Grande Portage Resources completed programs of rock, silt and soil sampling, geological mapping, airborne electromagnetic and magnetic surveys and a ground magnetometer survey on the area. In 2016 and 2017, Bridgeland Minerals completed a radar satellite and LiDAR orthophoto geological interpretation program on the area as the Blue Gold/Merry Widow property. In 2019, Mirva Properties Ltd. completed a rock sampling program on the Merry Widow property. In 2020, Roughrider Exploration Ltd. completed a program of rock, silt and soil sampling on the area as the Empire Mine property.
