5203 |a“The Montresor River area (parts of NTS 66-H/13, 14, 15, 16, and NTS 66-I/1, 2, 3, 4, 5, 6, 7, 8), part of the Rae structural province, is underlain by granitic rocks of Archean (ca. 2.6 Ga) age and the Paleoproterozoic (<2.19 Ga) Montresor group of metasedimentary rocks. Quartzite, dolostone and metapelite of the lower Montresor group are structurally imbricated (D1) with granitic gneisses and metamorphosed to the amphibolite facies. This structural footwall complex is separated from greenschist-facies rocks of the upper Montresor group by a detachment fault (D2). A third set of structures including mylonites juxtaposes the basal footwall complex and surrounding granitoid rocks carrying concordant augen gneissic fabric. The Montresor syncline, outlined aeromagnetically by prominent magnetic siltstone beds, may be a D4 structure. Previously unrecognized breccia and hydrothermally altered alkaline igneous rocks occur as a stratabound layer in the southwestern Montresor syncline and have elevated Cu, Ag, Au values"--Abstract.
