Province: Superior
Subprovince: Abitibi
Terrane: Wawa-Abitibi
Belt: Abitibi
Geological Age: Mesoarchean
Metamorphism Grade: Greenschist
Jun 24, 2015 (R Degagne) - Geological mapping indicates that the bedrock supracrustal assemblage is part of the (Archean) Kinojevis Group and that the Mine is on the north limb of the east striking and east plunging Blake River Synclinorium. The regional metamorphic grade is greenschist or lower metamorphic facies except marginal to felsic intrusive bodies, where amphibolite grade contact metamorphic aureoles may be developed. Most bedrock in the area is mantled by variable thicknesses of Pleistocene and Recent deposits.

Jun 24, 2015 (R Degagne) - Bedrock underlying the property consists mainly of 070 striking, steeply south dipping, and south facing subaqueously deposited basalt flows, minor intercalated rhyolitic flows, and interflow (variably tuffaceous) sediment. Geochemical analyses of rocks in the area indicate that the basalt is tholeiitic and the rhyolite is calc alkalic. Intrusive rocks in the area include (narrow) dikes of lamprophyre and syenite. A small (several hundred feet in diameter) porphyritic albite syenite plug has been identified via diamond drilling to subcrop about 500 feet west of the Harker Gold Mines No.1 shaft. A single north northeast striking diabase dike of the (Proterozoic) Matachewan swarm intrudes the supracrustal bedrock assemblage about 170 m east of the No.1 shaft. The quartz-calcite vein on which the 2 Harker Gold Mines shafts are sunk strikes 058º, dips south 83º, averages about 1 foot in width and is known to extend at least 3,000 feet along strike and from surface to at least the (vertical) 1,000 foot level. Where the vein is exposed at surface near the No.1 shaft, it is prominently ribbed and is hosted by hard, variably mauve colored carbonate bearing, sericitic, and pyritic rock which elsewhere in outcrop is weakly foliated and displays a fragmental (cataclastic) texture. A few tens of metres northwest of the No.1 shaft, unsheared, pillowed, light green nonmagnetic (Mg-rich) tholeiitic basalt is exposed, and south of the foliated fragmental horizon which hosts the vein, massive, nonsheared dark green magnetic (Fe-rich) tholeiitic basalt is exposed. The vein is 6-12 feet in width and 3000 ft. in length The vein material consists of quartz, carbonate and feldspar.

Jun 24, 2015 (A Wilson) - Native gold is visible as fine rosettes in the siliceous parts of the vein and local patches of mauve-coloured vein material yield high values. Specimens of well-pyritized basalt from the Harker Gold Mines vein, when analysed by the Provincial Assayer, was found to carry $51.40 in gold per ton. Another sample of grey feldspar porphyry impregnated with fine pyrite crystals carried $0.80 gold per ton. Assays from approximately 300 ft west of the shaft a narrow section of high-grade ore was encountered. Assays showed $34.30 over 19 inches and at 603 ft west of the shaft a 25 ft section of $15.00 material was encountered. Mineralization at the Iris and Golden Harker deposits is associated with alkalic intrusive rocks. Gold occurs with disseminated pyrite and quartz veins in the intrusions and surrounding metavolcanic rocks. Hematite and albite are common alteration minerals in the intrusive rocks, whereas hematite, epidote, chlorite and sericite are common in the metavolcanic rocks. Scheelite and rare molybdenite are reported as accessory minerals.
Dec 07, 2005 (R Degagne) - The quartz-calcite vein is reported (assessment files, Resident Geologist's Office, Kirkland Lake) to be variably brecciated, ribbed, lensoidal, and stringer like. Vein material is reported to consist of grey and white quartz with variable amounts of calcite and contains small rosettes of fine grained visible gold and, on the 1,000 foot level, coarse grained visible gold (Gledhill 1925, Carmichael 1988). Other sulfide minerals which occur in the vein include pyrite, galena, sphalerite, and chalcopyrite. Gangue minerals associated with the vein system include epidote, red garnet, calcite, sericite, quartz, and ilmenite (identified petrographically) (Gledhill 1925, Carmichael 1988).
Jun 24, 2015 (R Degagne) - Where the No.1 vein is exposed in a recently stripped area south of the No.1 shaft access road near the no. 1 post of claim no. 7306, it is hosted by variably Fe-dolomitized, calcite altered, sericitized, epidotized, and pyritic interflow sedimentary and tuffaceous rocks (samples AB-86-231 through -245). Peach colored felsic dike material is present in muck samples at this locality (samples AB-86-242 and -243), and quartz-garnet-pyrite veinlets (sample AB-86-232) may be developed. The vein here (sample AB-86-234) consists of narrow (decimetre scale) pyritic white quartz-albite hydrothermal material. Significantly anomalously elevated gold tenors from this area were found by the present writer to be associated with the No.1 quartz-albite vein (450 ppb Au, sample AB-86-234), with carbonatized and pyritic fine grained bedded interflow sediment spatially associated with the No.1 vein (1,060 and 410 ppb Au, respectively from samples AB-86-237 and -239), and with quartz-Fe-dolomite veins developed within pyritic, peach colored, felsic dike material (370 ppb Au from sample AB-86-242).
