We are planning a whole bunch of great trips for the 2015 meeting. Although nothing is guaranteed yet, here is a list of what we have so far to whet your apetite


Pre-Meeting trips

1. Red Lake (2 Day)

Tuesday May 19th and Wednesday May 20th, 2015
Leaders: Andreas Lichtblau (OGS) and Carmen Storey (OGS)

The Red Lake greenstone belt records ca. 300 Ma of episodic magmatism, sedimentation and tectonothermal activity along the southern margin of the 3 Ga North Caribou terrane. Gold production from the world-class Red Lake deposit exceeds 22M ounces. The field trip comprises a 20 km transect through the central portion of the camp, and focuses on several different styles of gold deposition and associated host rock alteration.
This trip requires an overnight stay in Red Lake on the evening of Tuesday, May19th (accommodation included in trip cost).

2. Western Wabigoon Subprovince Transect (Dryden to Meggisi Lake)

Wednesday May 20th, 2015
Leaders: Mark Puumala (OGS) and Dorothy Campbell (OGS)

Journey back in time 2.7 billion years to experience the Neoarchean geology of the Western Wabigoon Subprovince.  This trip follows the Highway 502 corridor between the City of Dryden and Meggisi Lake and will include opportunities to view beautiful exposures of isoclinal folds in the Thunder Lake metasedimentary rocks, exceptionally well preserved three–dimensional metavolcanic pillows, flow top breccias and “eyebrow” structures in the Wapageisi basalts, giant pillows of the Pincher Lake group, polymictic conglomerates of the Manitou group, granitic rocks of the Atikwa batholith, and finishing off  with a stop at a classic exposure of Archean lode gold mineralization.

3. Mine Reclamation and Legacy Issues at the South Bay Mine

Wednesday May 20th, 2015
Leader: Rob Purdon (MNDM)


This one day trip will explore environmental and legacy issues associated with the former South Bay Mine site 70 km NE of Ear Falls on Confederation Lake.  This copper-zinc producer operated from 1971 to 1981, producing 1.4 million tons of concentrate.  Following closure, surface infrastructure was removed and an aesthetic cover was placed on the tailings.  Although these measures met the requirements of the time, acid rock drainage from underground workings, tailings, mill site and waste rock areas has impacted surface water courses and there are several flow paths carrying this drainage to downstream lakes, including Confederation Lake which has a productive lake trout fishery.  The site was returned to the Ontario government in 1990 and the successor company attempted remediation through natural wetlands and ecological engineering.  These efforts were not successful and, commencing in 2004, MNDM has initiated design work for more conventional rehabilitation efforts.   The field trip will include stops at contaminant source areas, acid rock drainage areas and impacted lakes.  Discussion will include past efforts, options, current plans for site rehabilitation and the challenges to implementation. 

4. Geological Setting of the Thunder Lake Gold Deposit / Gold occurrences of Van Horne Township

Wednesday May 20th, 2015
Leaders: Treasury Metals Inc. Representative


This field trip will examine drill core and exposures at Treasury Metals Inc. Goliath Project located in the Wabigoon subprovince 20 km east of Dryden.  The mineralized zones at the Thunder Lake deposit are hosted within a felsic/intermediate volcanic schist, appearing as sub-vertical, tabular composite units defined on the basis of anomalous to strongly elevated gold concentration, increasing sulphide content and distinctive altered rock units which are concordant to the local stratigraphy. This trip will be paired with numerous gold occurrences hosted by the Lower Wabigoon Volcanics exposed in Van Horn Township approximately 8 kilometers south of Dryden.  The area was a hotbed of gold exploration from 1897 to 1920, during which time, 16 production mine shafts were sunk.  This field trip will examine exploration trenches around Flambeau Lake including some of the best examples of the complex volcanic stratigraphy and the quartz-carbonate vein systems that host the gold mineralization.

 
Syn-meeting trips
5. Classic outcrops of the Dryden Area

Friday May 22nd, 2015
Leader: Pete Hinz (MNDM)

The geology of the Dryden Area is highlighted in three stops within the Western Wabigoon subprovince.  The stops are part of a larger eight-stop field trip which was developed to educate high-school students on the geology of the Dryden area.  The stops will include photo-worthy outcrops including pillowed mafic lavas of the Boyer Lake Group, isoclinally folded Warclub Group sediments and finally folded iron formation displaying parasitic folds and contact metamorphic assemblages including garnet-biotite-sillimanite

6. Gold Occurrences of Van Horne Township

Friday May 22nd, 2015
Leader: Steve Meade (OGS)

Numerous gold occurrences are hosted by the Lower Wabigoon Volcanics exposed in Van Horn Township approximately 8 kilometers south of Dryden.  The area was a hotbed of gold exploration from 1897 to 1920, during which time, 16 production mine shafts were sunk.  This field trip will examine exploration trenches around Flambeau Lake including some of the best examples of the complex volcanic stratigraphy and the quartz-carbonate vein systems that host the gold mineralization

7. Unique mineralizing event at the Pidgeon Molybdenum Occurrence

Friday May 22nd, 2015
Leaders: Craig Ravnass (OGS)

During this ½ day field trip the molybdenite mineralizing event related to structure and lithology will be examined in an exposure located in the eastern part of the Lateral Lake felsic intrusion located 40 km northeast of Dryden
 
Post-meeting trips
8. Historic Pickle Lake Camp (1.5 day)

Friday May 22nd and Saturday May 23rd, 2015
Leaders: Mark Smyk (OGS) Peter Hollings (Lakehead University) and Neil Pettigrew (PC Gold Inc.)


This one-day trip will highlight base metal and gold deposits and recent exploration activity in the Meso- to Neoarchean Pickle Lake greenstone belt.  The past-producing Thierry (Cu-Ni), Pickle Crow (Au) and Dona Lake (Au) mines will be featured in a modern lithostratigraphic and structural context.
This trip requires an overnight stay in Pickle Lake on the evening of Friday, May 22nd (accommodation included in trip cost).

9. Ghost Lake Batholith and related pegmatites

Saturday May 23rd, 2015
Leader: Shannon Zurevinski (Lakehead University)

This 3/4 day field trip that will examine the 2685 Ma Ghost Lake Batholith, a peraluminous, S-type granite that is associated with rare-element pegmatites.  Outcrop visits will highlight some spectacular pegmatitic mineralogy

10. Mattabi/Sturgeon Lake Historic VMS Camp (2 day)

Friday May 22nd and Saturday May 23rd, 2015
Leader: George Hudak (UMD)

This trip requires an overnight stay in Ignace on the evenings of Friday, May 22nd and Saturday, May 23rd (accommodation included in trip cost).

The nearly 20 million tons of massive sulfide mineralization mined between 1972 and 1991 in the Sturgeon Lake region of northwestern Ontario were formed in a Neoarchean, piecemeal, explosive subaerial to submarine caldera complex known as the Sturgeon Lake Caldera Complex. The Sturgeon Lake Caldera Complex is considered one of the best-preserved Neoarchean caldera complexes in the world, and is considered by many to be the "type" Neoarchean explosive caldera complex. This two-day field trip will investigate key mineralogical, lithological and geochemical features related to the physical volcanology, hydrothermal alteration, syn- and post-volcanic structures, and VMS-style mineralization within this volcanic center. An emphasis will be placed on recognizing key lithological types and stratigraphic sequences that can be used to identify ancient caldera complexes, as well as distinguishing and evaluating various greenschist facies metamorphosed hydrothermal alteration mineral assemblages that can be used by exploration geologists to identify and distinguish synvolcanic- and post-volcanic structures that are utilized for targeting prospective VMS mineralization within caldera settings.


11. Geological Setting of the Goldlund Gold Deposit

Saturday May 23rd, 2015
Leader: Tamaka Gold Corp. Representatives

A one-day field trip will examine drill core and exposures at Tamaka Gold Corp. Goldlund Project located in the Wabigoon subprovince 40 km northeast of Dryden.  Mineralized zones at the Goldlund Deposit are associated with easterly trending intermediate intrusive rocks.  Gold is found in sub-structures within these intrusive rocks but also in surrounding mafic volcanic rocks
