Geophysical Data Acquisition and Interpretation provide regional airborne geophysical data, derivative products, concepts, ideas to support bedrock mapping.Technical initiatives & collaborations requiring PGS resources in 2011 & 2012: Technical initiatives & collaborations requiring PGS resources in 2011 & 2012 Far North Land Use Planning – ongoing mapping & airborne geophysical surveys Targeted Geoscience Initiative 4 - focus on Lode Gold and Cu-Ni-PGE + Cr across Ontario; airborne gravity survey and mapping in the McFaulds Region aka “Ring of Fire” Hudson Platform Geoscience – GEO-Mapping for Energy & Minerals (GEM) – airborne geophysical surveyFar North : Far North Collect new geoscience data to support CBLUP, mineral resource development, far north economy, jobs - Geoscience Gap Analysis – RoF - Support TEK mapping – Eabametoong - Collaborate with GSC – TGI4, GEMNew Regional Airborne Geophysics: New Regional Airborne Geophysics2010 Airborne Gravity Survey – McFaulds Region: 2010 Airborne Gravity Survey – McFaulds RegionWinisk River Airborne Magnetometer Survey : Winisk River Airborne Magnetometer Survey 76000 line-km; 20,000 sq. km., 300m line-spacing Understand basement structure and influence on overlying Paleozoic rocks Kimberlite, gold, Ni-Cu-PGE Hydrocarbon potential OGS “in-kind” support to GEMFar North Bedrock Mapping: Far North Bedrock MappingMcFaulds Region Bedrock Mapping & Compilation Project: McFaulds Region Bedrock Mapping & Compilation ProjectMcFaulds Regional Bedrock Mapping & Compilation Project - Second year of project - 124 diamond-drill holes, totalling about 30 000 m re-logged to date - 53 outcrop exposures mapped - on-going modelling and integration of geophysical data as part of interpretation - collaboration with TGI-4 GSC projects & Universities: McFaulds Regional Bedrock Mapping & Compilation Project - Second year of project - 124 diamond-drill holes, totalling about 30 000 m re-logged to date - 53 outcrop exposures mapped - on-going modelling and integration of geophysical data as part of interpretation - collaboration with TGI-4 GSC projects & UniversitiesStrong dextral shear in mafic metavolcanics - o/c data provides important structural data not always discernable in drill core: Strong dextral shear in mafic metavolcanics - o/c data provides important structural data not always discernable in drill core o/c of magnetite-bearing tonalite - numerous large o/c of plutonic rocks; high magnetic response misinterpreted as gabbro.Fort Hope Greenstone Belt – Bedrock Mapping Project: Fort Hope Greenstone Belt – Bedrock Mapping Project Miminiska Lake - 2011 Keezhik Lake - 2010Miminiska Lake Bedrock Mapping: Miminiska Lake Bedrock MappingNorthwestern Ontario: Northwestern OntarioSlide 16: Wabigoon Synthesis: Multi-Year Project Compile geoscience data in the region New compilation maps – 1:100 000-scale Update geology in key areas – geochronology, geochemistry, controls on mineralization, stratigraphyGold Distribution – Manitou Lakes: Gold Distribution – Manitou LakesSlide 18: Wabigoon Synthesis: Multi-Year Project Rowan-Kakagi-Cameron Lakes Project Update geology – geochemistry, geochronology Improve structural understanding & controls on gold Characterize alterationAlteration Distribution & Gold : Alteration Distribution & GoldNortheastern Ontario: Northeastern OntarioBartlett & Halliday Domes Project: Bartlett & Halliday Domes Project Update geology, stratigraphy, structure, alteration, geochronology Improve understanding of komatiite-hosted Ni-Cu-PGE & gold in the areaMidlothian Twp.: Midlothian Twp.Slide 24: Cot è Lake Au Gogama Bedrock Mapping & Compilation Project Understand critical geological relationships between Swayze & Shining tree areas Update geochemistry, geochronology, structural analysis Where does the Cadillac-Larder FZ go? controls on gold & Ni-Cu-PGE mineralizationSlide 25: Magnetite-chlorite veining in felsic flows – Hydrothermal alteration related to base metal Mineralization? Quartz-carbonate veining in Rideout Fault Zone - Brunswick Township – gold potential?Southeastern Ontario: Southeastern OntarioProjects in the CMB, Grenville Province: Projects in the CMB, Grenville Province Update geology, geochemistry, geochronology & metallogeny MSc - Ni-Cu-PGE in Raglan Hills & Moccasin Lake gabbros MSc - study 1090 to 1070 Ma plutons in the CMBSlide 28: Assess zinc & industrial mineral potential in marbles - pegmatite-related mineralization - porphyry copper-molybdenum ± gold potential related to syenite intrusions Ni-Cu-PGE in gabbros – Raglan HillsProject Planning: Project Planning Annual Process Strategic Thrusts Initiatives Projects Projects based on evaluated proposals Planning results formulate the program for the following yearYour Input Requested: Your Input Requested PGS would like to know: Geoscience problems that our expertise can be used to address Ideas for mapping that will assist or stimulate exploration Jack Parker (705) 670-5976 email@example.com You do not have the permission to view this presentation.
