Gramly (1977) has recently argued that competition over deer hids was the primary variable stimulating conflict and warfare among the Huron during Late Woodland times. This variable, as well as two others dismissed by him, is reviewed here.

The Mackenzie Mountains have more than 100 Zn-Pb showings. The objectives of the 2005 fieldwork were 1) to assess showings from a wide geographic area and stratigraphic range, 2) verify the assessment files, and 3) rank the showings on exploration potential. TIC, ART-EKWI, BEAR, ICE, KEG, RAIN, TAP, AB, and GAYNA were visited. Most of the showings are hosted in fractures with minor brecciation and very rarely, carbonate replacement. The main economic minerals are sphalerite and galena, but copper sulphide minerals are commonly present. Gangue minerals include dolomite, calcite, quartz, barite, and fluorite. The best targets for further exploration are considered to be showings hosted in strata that were limestone (at the time of mineralization) rather than dolostone; that exhibit strong chemical interaction between the host rock and fluid resulting in carbonate dissolution or replacement; and that have multiple generations of sphalerite and galena. BEAR, GAYNA, AB, and TIC are considered the most attractive exploration targets.

NTS 87-F/15 is underlain by the Kilian and Kuujjua formations of the Neoproterozoic Shaler Supergroup. The shallowly dipping strata define the nose and northern flank of the Holman Island Syncline. Carbonate, shale, and evaporitic rocks of the Kilian Formation are well exposed as cliff sections beneath capping sills, but also form a plateau in the west-central part of the map area, where a small, circular, gabbroic body is interpreted to be a laccolithic offshoot of an unexposed sill. The sharp, conformable contact between the Kilian Formation and overlying-Kuujjua Formation is exposed in the eastern part of the map area. Up to 6 Type 2 (diabasic) sills outcrop as stepped cuestas that strike north to northeast across the entire map area. Some of the sills appear to branch towards the southwest. Some sills appear to cut across the sedimentary strata at a shallow angle. Several steep, northeast and north striking lineaments (possible normal faults) occur in the western part of the map area.
