Lithology

Lithology Comments

Dec 07, 2005 (K R Kettles) - The stratigraphic succession in the vicinity of the prospect is comprised of mafic flows at the base, overlain by thin units of black carbonaceous sediments which are in turn overlain by argillaceous sedimentary rocks. The sedimentary rocks are overlain by a thin unit of mafic flow breccia and oxide facies iron formation. The uppermost unit is comprised of mafic flows. Rock units strike NW-SE and dip to the NE. Stratigraphic tops are to the NE. The volcanic and sedimentary rocks have been intruded by several differentiated gabbro sills. Metamorphic grade in the area has attained amphibolite facies. Mineralization is hosted in a sheared and altered ultramafic sill in iron formation. Two bodies of massive sulphides are located about 240 m apart on either side of an east-west trending fault. Pyrrhotite, sphalerite, pyrite and chalcopyrite have filled dilation zones along the noses of drag folds in metasedimentary rocks cut by metagabbro. The western body is about 10 m thick and about 140 m long. Both zones plunge moderately to the west, but the mineralization cannot be traced below the 60 m level.

Mineralization Comments

Oct 31, 2014 (K R Kettles) - Two bodies of massive sulphides are located about 240 m apart on either side of an east-west trending fault. Pyrrhotite, sphalerite, pyrite and chalcopyrite have filled dilation zones along the noses of drag folds in metasedimentary rocks cut by metagabbro. The western body is about 10 m thick and about 140 m long. Both zones plunge moderately to the west, but the mineralization cannot be traced below the 60 m level.

Dec 13, 2011 (A McKee) - DDH TB08010 High Grade Lake The hole intersected intercalated mafic volcanic rocks, siltstone, wacke, & 'quartzite-iron formation'. Massive sphalerite with chalcopyrite was intersected within a 5 m. wide section in metasediments, at 34 m., with additional sphalerite noted over a 1.5 m. wide section at 14.5 m. & a sub-metre wide section at 52.9 m. Pyrite-pyrrhotite ran from 0.1% to over 20% in sections throughout the hole. DDH TB08011 High Grade Lake The hole intersected siltstone-wacke & a thin mafic volcanic unit at the bottom of the hole. Semi massive to massive sphalerite with lesser chalcopyrite (up to 60% & 15% respectively), was intersected in sections over 0.75 to 3 m. widths. Accompanying pyrrhotite-pyrite ran up to 31 15%. The mafic volcanic rock was noted as hosting up to 5% combined sulphides including sphalerite. The majority of sulphide mineralisation is located at the interface between sediments & volcanic rocks. DDH TB08012 High Grade Lake The hole intersected intercalated sediments & mafic volcanic rocks including gabbro. It hit massive sulphides at the top of the hole over 6 m, with up to 65% sphalerite, 1% chalcopyrite & 5-40% pyrrhotite-pyrite noted. DDH TB08013 High Grade Lake The hole intersected mafic volcanic rocks & interflow wackes, siltstone, & argillite. Up to 5% combined pyrite-pyrrhotite was noted over 1-3 m. widths in several sections. No chalcopyrite or sphalerite was noted (see Results). DDH TB08014 High Grade Lake The hole intersected mafic volcanic rocks & interflow argillite & siltstone. Up to 3% combined pyrrhotite-pyrite was noted in several metre scale sections in all units. DDH TB08015 High Grade Lake. No mineralisation was encountered so the hole was terminated at 32 m. in argillite. The hole was designed to test continuity along strike. DDH TB08016 High Grade Lake The hole was designed to drill through the thickest portion of the HGL deposit (approx. 19 m. of 16% sphalerite, from historical drilling). A mineralised zone of 7.8 m. running approximately 12% sphalerite was intersected from 29.6 -37.4 m. Massive sulphides were interested between argillite & 'underlying' mafic volcanic rocks.

Jul 14, 2020 (Therese Pettigrew) - In their April 8, 2009 press release, Puget Ventures reported 27.08 m of 0.52 gpt Au, 58.16 gpt Ag, 53.01 gpt germanium, 20.77 gpt indium, 11.34% Zn, 1.68% Cu and 0.34% Pb, including 147 gpt Silver over 0.41 m from 34.59 m to 35 m in the High Grade Lake target in hole TB08010. They also reported 173 gpt Germanium over 1.0 m from 12 m to 13 m in the HGL target in hole TB08011 and 48.1 gpt Indium in hole TB08016 in the HGL target from 35 m to 36 m (Puget Ventures April 8, 2009 press release).

Alteration Comments

Dec 07, 2005 (K R Kettles) - In the vicinity of the prospect rocks have been carbonatized, silicified and contain abundant disseminated pyrite.
