1 Bedrock mapping and geological characterization in the northern Glennie domain, west-central Reindeer Zone Samantha Van De Kerckhove, Ryan Morelli and Dylan Deck Saskatchewan Geological Open House, 2017

2 Introduction 2017 bedrock mapping season in the northern Glennie Domain/Wapassini Sheet Last season of a project that started in 2014

3 Regional Geology, Reindeer zone Trans Hudson Orogeny 2017 study area is within the Glennie Domain/Wapassini Sheet Overall project transects Kyaska Sheet and Wapassini Sheet Transects the Tabbernor Fault (Corrigan et al. 2009)

4 Regional Geology, Reindeer zone Trans Hudson Orogeny 2017 study area is within the Glennie Domain/Wapassini Sheet Overall project transects Kyaska Sheet and Wapassini Sheet Transects the Tabbernor Fault N S modified by R. Maxeiner from Lewry et al., 1990

5 Bedrock mapping Supracrustal rocks are mostly mafic and intermediate volcanic rocks; minor sedimentary rocks and felsic volcanic

6 Bedrock mapping Main unit: felsic to intermediate pluton with slivers of supracrustal country rock

7 Bedrock mapping Minor late(r) intrusive rocks

8 Bedrock mapping: Supracrustal and Associated Rocks Form rafts, xenoliths and/or slivers highly attenuated mostly mafic and intermediate volcanic rocks Mafic volcanic rock Intermediate volcanic rock

9 Bedrock mapping: Supracrustal and Associated Rocks Form rafts, xenoliths and/or slivers highly attenuated mostly mafic and intermediate volcanic rocks mafic xenoliths

10 Bedrock mapping: Supracrustal and Associated Rocks Minor sedimentary rocks and felsic volcanic Associated plutonic rocks - gabbro Pelite

11 Bedrock mapping: Supracrustal and Associated Rocks Minor sedimentary rocks and felsic volcanic Associated plutonic rocks - gabbro Pelite Migmatitic gabbro

12 Bedrock mapping: Supracrustal and Associated Rocks Minor sedimentary rocks and felsic volcanic Associated plutonic rocks - gabbro Pelite Migmatitic gabbro Felsic volcanic rock

13 Bedrock mapping: Orthogneisses Main unit: felsic to intermediate pluton Dioritic to granodioritic, minor tonalite, quartz diorite, and quartz monzodiorite Gneissic diorite-granodiorite Stromatic migmatite

14 Bedrock mapping: Orthogneisses Main unit: felsic to intermediate pluton Dioritic to granodioritic, minor tonalite, quartz diorite, and quartz monzodiorite Homogeneous quartz diorite-diorite

15 Bedrock mapping: Late intrusive rocks Pegmatite and aplite dikes Granitic veinlets

16 Bedrock mapping: Late intrusive rocks Pegmatite and aplite dikes Pegmatite dikes Graphic texture in pegmatite

17 Bedrock mapping: Late intrusive rocks Anatectic granitic intrusions Ultramafic rocks Leucogranite

18 Bedrock mapping: Late intrusive rocks Anatectic granitic intrusions Ultramafic rocks Diatexitic granite

19 Bedrock mapping: Late intrusive rocks Anatectic granitic intrusions Ultramafic rocks Ultramafic intrusive rock

20 Metamorphism Upper amphibolite facies Partial melt No sillimanite or kyanite in the sediments Garnet porphyroblasts in leucogabbro Net-textured migmatite

26 Regional Structure Cross section - F3 and F4 differ from regional? - Transects anticlinorium hinge and Tabbernor Fault A B

27 Gold Economic considerations Map area located ~30 km NE of Seabee Gold Mine not many quartz veins documented VMS-type some gossanous sulphide rich outcrops

28 Economic considerations RMo Gossanous and magnetic outcrop southwest of White Lake B.Sc. Thesis Jared Squire Garnet, magnetite, hornblende and anthophyllite and/or cummingtonite mineralization

29 Economic considerations SV Currently staked by Eagle Plains Resources Ltd (100%) In 2000, Leader Mining and Pine Channel Gold Inc completed reconnaissance geological mapping and prospecting of the southeast shore of Redhill Lake (AF 63M ). Assays yielded elevated Zn, Co, Cu, and Ni Samples were taken from this location SMDI #2745 located 1km+ NE

31 Economic considerations: SMDI #0400 U and Th Originally identified by W.G.Q. Johnston while mapping the area for the Saskatchewan Geological Survey in 1974 UTM E UTM N K (%) U (ppm) Th (ppm) TCPS SMDI # DD SV

32 Conclusions Same rock types, but different structural characteristics on either side of the Tabbernor Fault Lack of targeted exploration in the area Potential for VMS-type alteration/deposits Late radioactive granites/pegmatites
