Province: Superior
Subprovince: Abitibi
Terrane: Wawa-Abitibi
Belt: Abitibi
Geological Age: Archean
Metamorphism Grade: Greenschist
Jul 29, 2016 (C Salo) - Geological mapping indicates that bedrock consists mainly of largely glacial drift covered weakly metamorphosed (greenschist or lower metamorphic facies) tholeiitic basalt and minor intercalated rhyolite and interflow sedimentary horizons of the (Archean) Kinojevis Group. Recent exploration work (as revealed in the assessment files) indicates that the interflow sedimentary horizons are volumetrically more important than suggested by Jensen (1982), Jensen and Langford (1985), and Satterly (1954). Bedrock stratigraphy strikes east northeast, dips steeply south, faces south, and occupies part of the north limb of the east striking and east plunging Blake River Synclinorium. Intrusive rocks in the area include what have been described as syenitic and lamprophyric dikes, albite syenite and pyroxenite intrusive bodies (as exposed several hundred metres west of the occurrence area on the Iris Gold Mines Ltd. property in southeastern Harker Township), and narrow (tens of metres in width) north striking diabase dikes of the (Proterozoic) Matachewan swarm.

Jul 29, 2016 (A Wilson) - A zone in mafic metavolcanics and rhyolite is 2 to 3 feet wide and contains a vein approximately 4 inches wide accompanied by parallel quartz stringers.

Jul 29, 2016 (A Wilson) - Three diamond drill holes drilled in the vicinity of the shaft returned assays up to 0.85 oz/t over 10 ft in DDH 1; 0.35 oz/t Au over 1 inch in DDH 2 and 0.070 oz/t Au over 5 ft. Assays from a quartz vein in the shaft excavated in 1917 by L.B. Howey, M.R. Howey, W.M. Cochenor and D. Willans returned values up to 1.9 oz/t Au
Jul 29, 2016 (C Salo) - Anomalous (greater than 0.01 ounce of gold per ton) gold tenors occur in at least two places on the prop: in southwest Holloway Township (at the site of the Coin Lake Gold Mines diamond drilling) and in central Holloway Township (at the site of the McIntyre-Porcupine Mines diamond drilling). The Coin Lake Gold Mines drilling intersected anomalous gold tenors within 'mineralized' (pyritic) rhyolite near qv and stringers. The best gold concentrations here are reported to be associated with the northern rhyolite contact, at the same strat. locatopm where an aurifrtous vein occurs at the Coin Lake Gold Mines shaft sev. hundred metres to the west. Pyritic sections are reported to occur frequently within the 120 foot thick fractured rhyolite but they are described to be discontinuously developed. The McIntyre-Porcupine Mines drilling intersected qcv and veinlets ranging from less than 1 inch to about 10 in width with which py, cp, asp, and po are associated. Although no assay data accompanies the drill logs in the assessment files, resampling of this core by Lenora Explorations in 1984 returned assays as high as 0.10 ounce of gold per ton from a 10 foot core length of pyritic vein material. The anomalous gold tenors which were revealed via resampling of the McIntyre-Porcupine Mines diamond drill core constitute the Lenora Occurrence. The Coin Lake Gold Mines drilling yielded significant core lengths of auriferous rhyolite, including 15' averaging 0.03 ounce of gold per ton, 21' averaging 0.02 ounce of gold per ton, 13' averaging 0.03 ounce of gold per ton, 16' averaging 0.057 ounce of gold per ton, and 34' averaging 0.02 ounce of gold per ton. A grab sample of rhyolite is also reported to have assayed 0.09 ounce of gold per ton. Lenora Explorations(?) resampled the old McIntyre-Porcupine Mines diamond drill core, and established that a ten foot core section of pyritic quartz vein material from this core assayed 0.10 ounce of gold per ton.
