Jun 24, 2015 (A Wilson) - Gold is hosted in a coarse-grained, pyritic syenite intrusion that is cut by north-striking quartz veins, which also contain gold and scheelite. An exploration ramp, 10 by 10 by 500 feet in length, provides underground access to the deposit. The Iris stock is a multiphased intrusion with 1) hornblendite and/or clinopyroxenite around the east and south periphery; 2) medium-grained syenite and/or monzonite mostly along the south part of the intrusion; and 3) coarse-grained syenite along the north and west flanks. The coarse-grained syenite is composed of centimetre-size perthite and anti-perthite crystals that comprise between 80 and 90% of the rock. Strongly chloritized mafic phenocrysts and trace amounts to 3% pyrite comprise the remainder of this phase. Only the coarse-grained syenite contains appreciable gold. Geochemistry of this phase indicates that the syenite is highly sodic and probably a result of late sodium-rich volatiles in the magma. The Iris deposit is 7 km south of the PDDZ and is not associated with any major structural features.
Dec 07, 2005 (R Degagne) - Bedrock in the area consists mainly of largely glacial drift covered weakly metamorphosed (greenschist or lower metamorphic facies) subaqueously deposited tholeiitic basaltic flow and related rocks of the (Archean) Kinojevis Group (Baker et al. 1982; Jensen 1982; Jensen and Langford 1985; Jensen and Baker 1986; Johnstone and Steele 1989; McClenaghan et al. 1988, 1987; Steele 1988). These rocks form a monoclinal succession which is uniformly northeast striking, steeply south dipping, and south facing. The Mine is about 4,000 m stratigraphically beneath (northwest of) the upper Kinojevis Group contact. At least two narrow (less than about 100 m wide) rhyolite horizons are intercalated with basalt in the deposit area, and interflow sediment (including iron formation) have been identified on claim nos. 802701 and 802954 (assessment files, Resident Geologist's Office, Kirkland Lake). Intrusive rocks in the area include a small albite syenitic plug and associated syenitic dikes which intrude basaltic and rhyolitic flow and related rocks; a pyroxenitic body located immediately south of and in contact with the syenite plug; narrow, often flow-contact controlled lamprophyre dikes (Satterly 1952); and a narrow, north northwest striking diabase dike.

Jun 24, 2015 (A Wilson) - Samples collected from the McDonald Claim in 1919 returned assays of $7.60 and $8.40. Highly anomalous gold values up to 0.40 oz/t Au were obtained from pyritic quartz and and rhyolite. Samples collected from a vein in the #1 pit (claim 9735) returned assays of $10.15 Au over 1.7 ft; $9.45 Au over 2.0 ft and $2.80 Au over 1.9 ft. Channel samples from the #2 pit returned values under $1.40. Samples from the #2 vein (claim L8650) assayed up to $1.35 Au. The #2 vein has been traced by trenching for more than 1000 ft. The No. 3 vein is located on the line between mining claim L9920 and L7308, two pits were put down on the vein with the best assay value being $3.15 Au over 14 ft.

Date: Jun 14, 1989
Geologist: R Degagne
Notes: The No.1 occurrence is reported to have consisted of a 5 foot wide pyritic shear. Dump samples consisted of glassy white quartz containing pyrite, galena, and chalcopyrite. The No.2 occurrence is reported (Satterly 1952) to consist of a narrow shear located at the contact between basalt and rhyolite. Quartz stringers within the shear were reported to contain less than 5% of pyrite. The No.2 occurrence consists of a narrow shear located at the contact between basalt and rhyolite. The vein is reported (Satterly 1952) to carry accessory pyrite, chalcopyrite, and galena as well as free (visible) gold. The No.4 occurrence consists of quartz stringers in rhyolite with associated traces of chalcopyrite and galena and locally as much as 20% of pyrite. Known gold mineralization which is currently (1988) believed by Perrex Resources Inc. to have economic potential is reported to be associated with shear zones oriented at azimuth 070-090. Such shears may be developed in basalt, in (silicified) rhyolite, and in the syenite plug. These mineralized shears were first recognized as a result the diamond drilling which was performed in 1986-1987. Mineralized(?) shears developed within the plug indicate that the shearing event may have been at least to some extent protracted because although some syenite hosted shears were clearly developed subsequent to the plug's solidification, others are reported to have formed prior to the magma's solidification. When hosted by basalt, an increase in fracture density and in the development of epidote and saussurite are noted proximal to shears. The silicification which affects the northern rhyolitic horizon appears to be at least in part late stage (post syenite), as syenitic dikes intrude silicified rhyolite and silicified syenite has been noted (D. Hawke, pers. comm.).
