Geology Comments

Mar 08, 2010 (J Bongfelt) - Satterly (Vol. L, Part 2, OEM Annual Report, 1941, Map No. 50e, The Dryden-Wabigoon Area) indicates that the present property is underlain by diorites, quartz-hornblende diorites, and some porphyritic biotite granodiorites that comprise the extreme eastern border zones of the very large Atikwa Batholith. Satterly's contact between the felsic to intermediate batholithic rocks, and a very thick pile ofnorth-south striking, slightly metamorphosed, intermediate to mafic volcanic rocks occurs approximately 100m north of Emmons Lake. On Satterly's map gabbroic rocks occur in minor quantities immediately south of Emmons Lake, however later exploration work indicates that most of the rocks near Emmons Lake are mafic volcanic medium-grained gabbro, pyroxenite, peridotite and locally aplitic dikes and sills. The majority of the intrusive rocks which underly the property can be classified as border phases of the large Atikwa Batholith, which is centered some 30 kilometers to the west. The most recent mapping which covers the Emmons Lake area goes back to 1940 (Satterly, 1940).

Lithology

Lithology Comments

Mar 08, 2010 (J Bongfelt) - H.L. King, (Ontario Dept. of Mines) reported in 1970 that a dark grey, gabbroic rock with unaltered pyroxene and containing inclusions of light grey diorite and fine grain andesite, is the host rock for the mineralization. A breccia texture characterized by rounder fragments (or inclusions) occurs within the mineralized zone. Several quartz veins and narrow granitic dykes (several inches to 2' wide) cut the mafic rocks. Patches of disseminated sulphides consisting of pyrrhotite, chalcopyrite and pyrite have been exposed in 6 trenches, which occur over an area of about 300 feet by 130 feet. Mineralization is generally confined to the darker gabbro but some of the inclusions are also mineralized. In 2000, prospectors S. Johnson and J. Bond II, C. Ravnaas and the author (A. Raoul) visited the site. An inspection of the Emmons property located one main trench and several small pits on the western shoreline of Emmons Lake. The main trench is approximately is 15 m long x 1.2 m wide x 0.6 m deep at an orientation of 240°. The mineralization appears to be a result of hydrothermal alteration fluids. * Main trench sulfide sample: Sulfide-bearing Gabbro. A medium-grained, black gabbro with sulfides (3-5% pyrrhotite, 1-2% pyrite, 1-3% chalcopyrite) and limonite (>5%). The gabbro is composed of greater than 70% hornblendeactinolite, formerly pyroxene, with 15-20% weakly bleached plagioclase. (Assay: >2000 ppm Ni) * Main trench unaltered to weakly altered host rock: Gabbro to Diorite. This sample is representative of the unaltered rock around the trench area. A fine to mediumgrained, spotted, black and white, diorite to gabbro 50-55% hornblende (pseudomorphic after pyroxene), 35-40% plagioclase with 1-2% finely disseminated pyrite. Several weakly silicified zones (1-5 cm) with less than 20% silica replacement and intense grain size reduction are present within this trench but are most prevalent in these unaltered rocks. (Assay: 1121 ppm Ni). [Kenora Property Visit File 52F10SE00046, Emmon Occurrence]

Mineralization

Mineralization Comments

Mar 08, 2010 (J Bongfelt) - 1960 - Newcomex Limited drilled 10 holes (112.5m) on the Lantz Option, all resulting in above grade requirements: 0.37% to 1.02% Cu and 0.17% to 1.34% Ni. The sulphide mineralization encountered is finely disseminated over core lengths up to 25 feet or so, with some heavier concentration over a few inches, in places. The mineralization occurs in the medium grained diorite and to a lesser extent in the coarse diorite and quartz diorite. 1998 - Anomalous copper-nickel and elevated platinum-palladium was detected in the main trench at the Emmons Occurrence by Peter Hinz of MNDM. Gabbro with sulfides assayed 4514 ppm (0.45%) Cu and 3405 ppm (0.34%) Ni. 2000 - A property examination produced two grab samples assaying >2000 ppm and 1121 ppm Ni. [Kenora Property Visit File 52F10SE00046, Emmon Occurrence] 2008 - Canadian Arrow Mines assayed from grab samples: 0.34% - 1.57% Ni and 0.75% - 7.10% Cu. Nine samples contained elevated PGM+Au values between 0.141 to 1.24 gpt. 2009 - Prospect status of the Emmons Project is determined by drill results that coincide with significant surface sample assay results that Canadian Arrow Mines received the year prior re: 0.13% - 0.74% Ni and 0.33% - 0.62% Cu. [News Release - Jan.19/CNW/Canadian Arrow Mines, Ltd., Emmons Project]

Nov 04, 2022 (Therese Pettigrew) - Copper and nickel mineralization occurs disseminated in irregular patches over an area of about 300 feet by 130 feet in Early Precambrian gabbroic rock containing inclusions of diorite and andesite. Chalcopyrite, pyrrhotite and Niccolite have been identified. The best intersection reported was from DDH 1, where assays of samples taken from 0 to 17.2 feet averaged 1.34% Ni and 1.02% Cu (SDMR 000482).
