Point Location Description: taken from DDH map presented in AFRO 2.40343
Location Method: Based on Assessment
Access Description: The DC showing is located approximately 25 km NNW of the town of Savant Lake and approximately 90 km from the town of Sioux Lookout and within NTS map sheet 52J/6. Access to the property is by a logging road (Moose Lake road) located along highway 516. Secondary access roads and quad trials provide access to the main portion of the property.
Historically, this area has been explored for gold, specifically in the “Queenston” gold zone. It appears that the gold-bearing quartz vein zone was originally discovered in the 1920's or 1930's, based on the apparent age of trenches. Later work included exploration for nickel and the discovery of the “Willie Lake Zone” also referred to as the “DC Creek nickel occurrence” in later work. 1958: The first reported work on the property was a diamond drill program that was completed on the “Queenston” gold showing by Queenston Gold Mines Ltd. A total of sixteen holes were drilled totaling approximately 1,970 feet but no assays from this drill program are available. 1965: Falconbridge Nickel Mines Ltd. completed a reconnaissance magnetic and vertical lookE.M surveys over the north-west part of the property (Hudec, 1965). 1972: Nolan Cox and David Thorsteinson sampled the old trenches in the Queenston gold zone. 1976: B.B.M Investments Ltd. completed tractor scrapping and re-sampling over the Queenston gold zone. 1985: Dome Exploration Ltd. completed ground magnetic and horizontal loop E.M. surveys over a grid covering the Queenston gold zone. In 1986 they completed 8 diamond drill holes totalling 906.5 meters on the grid. Hole 232D-7 cut 2.05 g/t AU over 1 meter in a sulphide-bearing iron formation. 1987-1988: Northern Dynasty Explorations Ltd. completed a reconnaissance program which led to the discovery of the “Willie Lake Zone” (later referred to as the DC Creek nickel occurrence). Anomalous nickel (up to 1.63%) in surface samples was reported as well as anomalous nickel (up to 53709 ppm), cobalt (up to 2607 ppm), gold (up to 4175 ppm) and silver (3747 ppm) in soil samples. 1992: G. Gorzynski and H.E Ewen completed limited magnetic and VLF surveys as well as a soil survey over the DC Creek Nickel occurrence. Chip samples were also taken across the nickel occurrence giving an average of 0.65% nickel across 6.5 meters. 1997: Fairchild Gold Explorations Ltd. Sampling completed in the Queenston gold zone along with geochemical and geophysical surveys of the DC Creek nickel occurrence. 2006-2007: Benton Resources Corp. completed line-cutting, prospecting, grid mapping and soil sampling, trenching (phase I and II) and geophysical surveys (ground magnetic, HLEM, and IP) on the cut grid. 2008: Benton Resources completed 2 holes of DC Showing as part of a 13-hole program on the property.

Geological Age: Precambrian
Nov 24, 2014 (C Ravnaas) - The geology of the Savant Lake area has been described by Trowell (1986, 1988). The Armit Lake property is located on a WNW-trending arm of the Savant Lake greenstone belt. It is underlain by rocks of the Jutten Group which is composed of mafic and ultramafic volcanics as well as sediments. The sediments include a chert-magnetite iron formation, silica-grunerite iron formation and cherty units often containing fuchsite (no magnetite). The rocks of the Jutten Group form a 2-3 km wide belt that trends WNW from the west end of Kashaweogama Lake to the south end of Armit Lake. The belt is bounded by granitic to granodioritic rocks of the Dickson Lake Pluton to the north-east and the Fairchild Lake Intrusion to south-west (Reference: Benton Resources, Kenora Assessment File 52JNW0047 and AFRO # 2.40343).
Mar 04, 2011 (C Ravnaas) - Ultramafic Volcanic Ultrmafic rocks were typically blue/green in colour, fine to medium grained, and pervasively altered. Alteration minerals most commonly encountered were serpentinite, talc and magnetite. Sulphide mineralization, when present, was most commonly fine grained and disseminated; the most common minerals being pyrrhotite and pyrite. Semi-massive sulphide mineralization was occasionally encountered with pyrrhotite being the primary sulphide mineral. Mafic Volcanic Most commonly this unit was found to be a medium green coloured, fine to coarse grained volcanic, usually exhibiting amphibolite grade metamorphism. Alteration was commonlyweak, with chlorite being the most common alteration mineral observed. Locally, intense foliation was observed forming small scale shear zones. Sulphide mineralization within this unit was primarily fine grained, disseminated pyrite. Chemical Sediments Two forms of this unit were observed during drilling; the first being a magnetite-bearing iron formation, the second a variable cherty unit which does not possess iron but was occasionally observed to contain fuchsite; a chromium mica. The chromium zones were found to be 1-3 m wide and occasionally contained sulphide mineralization in the form of fine grained pyrite. The chromium zones often found to be adjacent to ultramafic units and are most like the result of hydrothermal alteration of the ultramafics. The structural geology of the property was found to include a single phase of variable intensity pervasive mineral foliation exhibited primarily in the mafic volcanic unit. This foliation was found to typically trend at 120º/90º but was found to vary between 110º and 155º Az. (Reference: Benton Resources, Kenora Assessment File 52JNW0047 and AFRO # 2.40343).
Mar 04, 2011 (C Ravnaas) - Occurrence based on: 1987-1988: Northern Dynasty Explorations Ltd. completed a reconnaissance program which led to the discovery of the “Willie Lake Zone” (later referred to as the DC Creek nickel occurrence). Anomalous nickel (up to 1.63%) in surface samples was reported as well as anomalous nickel (up to 53709 ppm), cobalt (up to 2607 ppm), gold (up to 4175 ppm) and silver (3747 ppm) in soil samples (Reference: Benton Resources, Kenora Assessment File 52JNW0047 and AFRO # 2.40343) Prospect based on: Drill - hole 08 that assayed 1.57% nickel (Ni) and 0.08% cobalt (Co) over 7.8 metres (m) from 32.0m to 39.8m down hole in an altered ultramafic rock unit. Within this intersection, was a narrower but higher grading material of 3.7% Ni and 0.2% Co over 2.55m. Hole 08 was drilled under the DC Creek nickel showing where selected surface grab samples returned up to 4.17% Ni (Reference: Benton Resources, Kenora Assessment File 52JNW0047 and AFRO # 2.40343 and Benton Resources, press release, May 28 2008).
