Capsule Geology

The Bliss occurrence is located on a ridge approximately 6.8 kilometres east of the mouth of Munro Creek on the Manson River, about 58 kilometres northwest of the community of Mackenzie.

The area lies within the Omineca Belt, which consists of siliciclastic sediments with minor carbonates and mafic rocks. These rocks belong to the late Proterozoic Ingenika Group. Within the Wolverine Range, the sediments are highly metamorphosed and subsequently intruded by granodioritic bodies and associated pegmatites, which are most likely Early Tertiary. The Proterozoic Wolverine Complex rocks consist of amphibolite and calc-silicate gneiss, schists, micaceous quartzite and crystalline limestone.

Locally, a number of en echelon tabular bodies of quartz-rich quartzofeldspathic biotite gneiss along the margin of an intrusion of fine-grained granite hosts allanite in a matrix of diopside, quartz, apatite, magnetite and accessory titanite and scheelite. Mineralization has been mapped over an area of 550 by 110 metres.

In 2010, a sample (E922522) assayed 3.500 per cent lanthanum, 3.970 per cent cesium, 0.301 per cent praseodymium, 0.722 per cent neodymium, 0.050 per cent samarium, 0.085 per cent niobium and 0.011 per cent europium (Assessment Report 31947).

In 2011, select samples of allanite bearing “dike” structures assayed up to 11.4 per cent total rare earth oxides plus yttrium (TREO+Y), while trench sampling, from trenches TR11-05 and TR11-08, yielded 1.97 and 1.98 per cent TREO+Y over 4.0 and 3.4 metres, respectively (Assessment Report 32770).

During 2006 through 2011, Paget Minerals completed programs of rock and silt sampling, geological mapping and a combined airborne magnetic and radiometric survey, totalling 564.4 line-kilometres, on the area known as the Mount Bisson property.
