The Blue Lake property is located near the head of Mudflat Creek on the northeast side of the Rocher Deboule Mountain Range, 9 kilometres south of South Hazelton.
Several mineralized quartz veins occur in porphyritic granodiorite of the Late Cretaceous Rocher Deboule stock of the Bulkley Intrusions. The intrusion contains a few rafts of hornfelsic argillites from the Middle Jurassic to Lower Cretaceous Bowser Lake Group rocks, the main body of which outcrops to the east.
The more easterly, or No. 1 vein, strikes 105 degrees and dips 65 degrees northeast. It is a quartz vein carrying up to 10 per cent tetrahedrite and minor chalcopyrite, ranging up to 25 centimetres in width.
Less than 30 metres distant, the No. 2 vein strikes 155 degrees, dipping 70 degrees southwest. It contains chalcopyrite, pyrite, molybdenite, tetrahedrite, scheelite, and likely uraninite. A grab sample assayed 0.85 per cent molybdenum, 1.0 per cent WO3 and 0.004 per cent equivalent uranium (Geological Survey of Canada Memoir 223 Rev.).
The No. 3 vein is located six hundred metres to the northwest. It strikes 165 degrees and dips 75 degrees west. It is a quartz vein with scheelite, molybdenite, chalcopyrite, and ferberite. A grab sample assayed 2.74 grams per tonne gold, 11.31 per cent WO3, 0.06 per cent molybdenum, and 0.003 per cent equivalent uranium (Geological Survey of Canada Memoir 223 Rev.).
Another vein, 90 metres below the No. 3 vein, is exposed for 23 metres. It is up to 3 metres wide, strikes northwest and dips 60 degrees northeast. It contains milky white quartz and tetrahedrite and a sample assayed 0.7 gram per tonne gold and 1900 grams per tonne silver ((Geological Survey of Canada Memoir 223 Rev.).
In 2017, Primary Cobalt Corp. completed a program of prospecting and rock and stream sediment sampling on the area as the RD Cobalt property. In 2018, Primary Energy Metals Inc. completed a program of geological mapping and geochemical (rock, soil and stream sediment) sampling on the area as the Golden Wonder property.
In 2019, Blue Lagoon Resources Inc. completed a program of geochemical (soil and rock) sampling and a ground magnetic survey on the area as the Golden Wonder property.
