Metamorphism Grade: L. Amphibolite
May 01, 2015 (Therese Pettigrew) - The Marshall Lake property area comprises of a sequence of Neo-Archean calcalkaline metamorphic-volcanic rocks and volcanogenically-derived clastic and chemically-derived metasedimentary rocks within the Marshall Lake Series, an accumulation of felsic to intermediate bimodal rocks over 9000 m thick. The property is situated on the southern limb of a regional antiformal fold at the top of the Marshall Lake Series and is a deformed acidic metavolcanic complex. It is comprised of a large dacitic volcanic pile located on the northern margin of the Onaman-Tashota greenstone belt within the eastern portion of the Wabigoon Subprovince. The geology of the area is dated at 2739 Ma (Nielsen et al., 2010).

May 01, 2015 (Therese Pettigrew) - The Marshall assemblage is an east-trending assemblage comprised of felsic to intermediate composited volcanic rocks including volcaniclastic, effusive units and porphyritic felsic intrusions, intruded by Proterozoic mafic dykes trending north-south. The felsic volcanics range from massive aphyric to quartz-feldspar phyric flows, tuffs, lapilli tuff (massive and banded), ocarse agglomerates and breccia units and consist of between 80-90% of the rocks on the Marshall Lake property. Both clastic and chemical metasedimentary units and conformable mafic flows overlie the assemblage. The clastic metasediments are derived from weathered portions of the underlying felsic stratigraphic pile and deposited flanking the deposit. The chemical metasedimentary rocks comprise of a regional banded iron formation to the east and south of the felsic pile that is composed of oxide-sulphide iron facies and ferruginous chert layers (Nielsen et al., 2010).

May 01, 2015 (Therese Pettigrew) - The Marshall Lake property is defined and classified as a primitive type bimodal mafic type volcanogenic-hosted massive sulphide (VHMS). VHMS mineralization and associated synvolcanic alteration assemblages are evident in the felsic to intermediate volcanic pile. The volcanic environment of deposition indicates a growing subaqueous felsic dome in a relatively shallow water depth, which on the margins, flow front breccias and hyaloclastics developed. Slumping and reworking formed both debris flows and bedded flows. The metavolcanics were sourced from several volcanic centres, defined by pumice dispersal areas and coarse-grained pyroclastic rocks. Immediately overlying the felsic pile and underlying the regional conformable banded iron formation, is evidence of discharge vents for hydrothermal solutions evidential by hydrothermal explosion breccias around Marshall Lake in the east of the property. Mineralized samples are the RSM-series samples from RSM-06-011 to -015. The samples have anomalous Cu, Pb and Ag contents and highly anomalous Zn contents of 5450 ppm Cu, 515 ppm Zn and 56.6 ppm Ag in -011; 8890 ppm Cu and 58.5 ppm Ag in -012; 2.71 % Cu, 18.05 % Zn, 7730 ppm Pb and 276 ppm Ag in -013; 2.05 % Cu, 10.2 % Zn, 2470 ppm Pb and 168 ppm Ag in -014; and 6420 ppm Cu, 2630 ppm Zn and 29.4 ppm Ag in -015. Samples -013 and -014 also have anomalous Bi at 552 ppm in -013 and 262 ppm in -014. Anomalous Fe contents in the samples are 10.75 %, 8.89 %, 13 % and 9.78 % from samples -011 to -014 (Nielsen et al., 2010). DDH Mar-23-01 returned 1.32% Cu, 5.37% Zn, 138.20 g/t Ag, and 0.44 g/t Au over 3.82 m from 111.18 m depth, including 4.14% Cu, 10.40% Zn, 532.0 g/t Ag, and 1.69 g/t Au over 0.55 m. The same hole also returned 1.86% Cu, 4.25% Zn, 171.5 g/t Ag, and 0.67 g/t Au over 1.6 m from 334.75 m depth including 5.66% Cu, 3.01% Zn, 239.0 g/t Ag, and 1.96 g/t Au over 0.3 m (Copper Lake Resources news release April 19, 2023).
May 01, 2015 (Therese Pettigrew) - The distinctive original synvolcanogenic alteration assemblages that occur in the Marshall Lake VHMS system such as seritization, chloritization, and silicification, have all been metamorphosed to lower amphibolite facies to produce a distinctive assemblage of lower amphibolite grade metamorphic minerals.
