The Chilliwack - Harrison Lake region occupies an important position in a mid-Cretaceous to Cenozoic (100-45 Ma) orogen whose southern extent geographically coincides with the Coast and Cascade Mountains of southwestern BC, and the Cascade Ranges of Washington State. We informally refer to this orogen as the "Coast-Cascade orogen". In this region there is excellent preservation of the allochthonous terranes that were sandwiched between terranes to the east previously accreted to the pre-Cordilleran continental margin of North America in the Jurassic, and Wrangellia terrane to the west that underlies most of Vancouver Island. The Coast-Cascade orogen is characterized by mid-Cretaceous to early Cenozoic granitic intrusions, associated metamorphic rocks, and by folds, thrust and reverse faults that diverge eastward and westward from an axis within the present mountains. The southern part of the CCO is overprinted by late Eocene through Neogene (~34-0 Ma in this region) volcanic rocks and plutons of the Cascade Magmatic Arc, whose volcanic rocks bury the CCO south of about latitude 47°N. The purpose of this 2-day field trip is to examine rocks and structures in two areas, discuss their association with each other and their paleogeographic affinities. One area is in and around the Chilliwack Valley south of the lower Fraser River (Day 1) and the other area is north of it on the east side of Harrison Lake (Day 2). The former area lies within the Cascade Mountains (called the North Cascade Ranges in Washington) and the latter in the southeastern Coast Mountains.

7 days - Saturday June 9 to Friday June 15, 2018

$2 250 Include: transportation, luncheons, accomodation and guidebook

This seven-day long field trip focuses on the porphyry Cu-Au systems in the prolific Late Triassic Quesnel Terrane(Quesnellia) of southern British Columbia. It will provide participants with exposure to various types of porphyry deposits, mineralization and alteration styles, mining methods and background lectures. In particular, participants will see alteration types associated with alkaline porphyry systems. Participants will also be exposed to the Anaconda Mapping Method, which can be variably practiced at surface and bench mapping scales as well as a MDRU-modified approach for core-logging. Participants will include a mix of industry and MDRU graduate students and researchers. For UBC students, this trip is part of a course requirement.

The course is based in the southern Quesnel Terrane around the porphyry deposits near Kamloops and the Copper Mountain district, near the town of Princeton. These represent important alkalic Cu-Au porphyry deposits that characterize British Columbia's metallogeny. The regional geology is also characterized to provide context to the nature of the Late Triassic arc whence the deposits formed. The region is well-exposed and the open pits and surrounding outcrops provides a fantastic natural laboratory. Evening lectures will provide insight, context and an opportunity for discussion and socializing.

The course will provide an introduction to the mapping of alteration, lithology, mineralization and structures associated with porphyry deposits. The focus will be on the field techniques and methodology, but the course will also provide a good field introduction into the geology of alkalic porphyry Cu-Au systems and include technical presentations and discussion on setting of BC porphyry deposits and alterations applied to exploration of porphyry copper deposits. Participants should be comfortable underground, in open pits and on uneven terrain and have appropriate boots and clothing.

Fees include all transportation, accommodation, and training materials. Lunches will be supplied most days: breads, cheese, meat, cookies etc. Breakfasts and dinners are not supplied but continental breakfasts are available at the hotel. Welcome and farewell BBQs are included with registration. Otherwise, individuals have the opportunity to select from a variety of dining options in the towns of Kamloops and Princeton. Participants are expected to bring outdoor gear appropriate for cold & windy weather, a knapsack, water bottle, as well as typical mapping equipment for a minesite such as rock hammer, hand lens, notebook, and PPE (CSA-approved safety boots, safety glasses, hard hats and safety vest required; please bring your own).

Participants with an interest in porphyry copper systems, particularly the alkaline variety, and an appreciation of alteration types and styles will get the greatest benefit from this course.

$1160 Include: transportation, meals, accomodation and guidebook

This MAC-sponsored field trip visits the Upper Fir carbonatite-hosted Nb-Ta deposit in the Blue River area, east-central British Columbia. The area is within the Omineca belt of the Canadian Cordillera, at the northeastern margin of the Shuswap metamorphic complex, in the Monashee Mountains. Metacarbonatites and associated ultramafic and alkaline rocks of at least two age groups (ca. 500 and 360-330 Ma) and the enclosing (semi)pelites and amphibolites of the Mica Creek assemblage (750-550 Ma) in the Blue River area underwent multiple deformational phases, anatexis at peak metamorphism, and exhumation during the Cordilleran orogeny.

Upper Fir is the largest and best-studied Nb-Ta deposit in the area, hosting an NI 43-101 compliant resource of 48.4 million tonnes (indicated category) averaging 1,610 ppm Nb2O5 and 197 ppm Ta2O5 plus 5.4 million tonnes (inferred category) averaging 1,760 ppm Nb2O5 and 191 ppm Ta2O5. Ore minerals are mainly Ta-rich pyrochlore and ferrocolumbite, with minor fersmite, niobo-easchynite, and microlite. In addition, centimetre-sized molybdenite books occur sporadically in both carbonatites and fenites, containing up to 1,386 ppm Mo over a metre-long drill core intervals at Upper Fir. Molybdenite hosted by carbonatites and related rocks was found in several other Cordilleran occurrences, including Perry River, Mount Grace, Wicheeda Lake and Mount Copeland (former Mo producer). Unlike unmetamorphosed and greenschist-facies metacarbonatites in British Columbia, REE carbonates are yet to be found in the upper amphibolite-facies metacarbonatites of the Blue River area.

Participants of this field trip will see representative drill-core sections and outcrops of carbonatites, related alteration and alkaline rocks, and the enclosing rocks of the Mica Creek assemblage at Upper Fir. We will discuss the primary igneous features and tectono-metamorphic overprinting of the Upper Fir carbonatites, recorded by their paragenetic relationships, mineral chemistry, recrystallization and retrograde mylonitization. Highway travel from Vancouver to Blue River transects a number of different Cordilleran terranes. We will have a few stops along the way to look at pillowed and massive basalts of the Fennell Formation (Late Paleozoic), Slide Mountain oceanic terrane, and at the Quaternary volcanic landforms, basaltic flows, hyaloclastite, fluvial and till deposits in the Clearwater valley.

We will use a 56-passenger charter bus and a helicopter to ferry crews from a bus drop-off/pick-up location in the valley downslope from Upper Fir and the deposit at about 1,240 m above sea level elevation. Participants will need to be physically and logistically prepared to spend a full day in potentially cold and wet conditions, and to walk about 2 km on rugged, deactivated exploration trails and excavated sites. Therefore, everyone must bring adequate personal gear, including warm and waterproof clothing, safety-toed boots, hat/toque, gloves, sunscreen, etc. Because the itinerary includes rugged bulk-sample cuts, participants need to wear safety-toed boots and hard hats. Inclement weather or elevated risk of wild fire may cancel the Upper Fir itinerary, in which case we will have more time to examine the Commerce Resources Corp.’s drill-core from Upper Fir in Blue River.

2.5 days - Friday, June 22 to Sunday, June 24, 2018

$470 Include: transportation, luncheons and accommodation

This 2.5-day field trip will examine the geology, hydrothermal alteration mineralogy, and geochemical dispersion around Yerington, Nevada. Yerington is a classic locality where porphyry Cu deposits, high level Fe-oxide deposits, and volcanic and plutonic complex have been tilted 80° on to their side so that a complete 3-D picture of a zoned magmatic-hydrothermal system is exposed. Day 1 of the field trip will focus on the geology of the porphyry Cu system beginning 3 km beneath to the level of copper precipitation. Day 2 will focus on the upper 3 km of the porphyry Cu system. Each day will link the geology of the tilted system with the alteration mineralogy together with the whole rock major and trace element geochemical changes in rocks that can be mapped using modern exploration methodology. Short hikes of up to 2 hours in duration are involved each day.

Collect participants in Reno, and drive to Yerington. Travel to and from Reno will be the responsibility of the field trip participants. Individuals will be picked up at 5 PM at the Best Western Airport Plaza Hotel across the street from the airport (5 to 10 minutes from baggage claim by foot). There will only be one (1) pick-up time, as will have a 90-minute drive to Yerington. The contact for the hotel meeting place in Reno is 1981 Terminal Way, Reno, Nevada, 89502-3215 (US Phone: 775-348-6370; Fax: 775-348-9722; Toll Free Reservations: 800-648-3525). Reservations if needed are responsibility of participants.

Tour Day 1: Review of 80°W-structural tilting of the mineralized Jurassic rocks due to late Cenozoic normal faulting. Examination of deep exposures of the Yerington batholith in the Ann-Mason fault block including contact and age relations of plutonic intrusions with one another and the timing of sodic-calcic and endoskarn alteration relative to pluton emplacement. We will review inferred flow paths of non-magmatic sedimentary brines that likely produce these sodic alteration types, and examine the timing, spatial relations, and geochemical changes of these alterations with K-silicate and sericitic alteration due to magmatic fluids. The morning includes an overview of the Yerington Mine and the deep (6 km) plutonic hydrothermal features in the Ann-Mason area. The afternoon examines the root zone of the Ann-Mason porphyry copper deposit, where the deep causative pluton and related porphyry dikes are observed about 1 km below (in Jurassic position) the copper ore zone (1,137 MT @ 0.33 wt.% Cu at 0.2% cutoff; We traverse upward through the porphyry hydrothermal system and end by examining sodic-calcic and K-silicate alteration near the periphery of the orebody, where they are cut by late sodic and sericitic alteration near the Ann-Mason discovery area. Throughout the day we review geologic concepts that allowed Anaconda to discover this deposit, including tilting, geophysics, intrusions, alteration, and geochemistry. Evening lecture outlining the geology and geochemical dispersion in the Yerington district will be presented.

Tour Day 2: We will traverse west to the Blue Hill and Buckskin Range areas, where the upper parts of the magmatic-hydrothermal plume and subvolcanic environment above the porphyry systems are observed. Here, sericitic alteration gives way upward to quartz-alunite-altered volcanic and volcaniclastic sedimentary rocks, massive silica replacements with pyrophyllite, and various breccias and pyrite-rich mineralized rock. The timing of high-level hydrolytic alteration relative to porphyry intrusions and sodic-calcic and propylitic alteration will be examined. We will end with a discussion of possible flow paths for magmatic and non-magmatic fluids through time in the Yerington system, and potential sources and sinks of saline fluids, Fe, Cu, Au, and sulfur, as well as the geochemical effects of the various fluids on the host rocks.

Return to Reno at the Airport Plaza Inn about 5:00 PM. Note, there are no early departures unless one provides the transportation themselves.

2.5 days - Friday, June 22 to Sunday, June 24, 2018

$600 Include: transportation, luncheons, accomodation and guidebook

This 2.5 day post-conference field trip (June 22-24) will examine the magmatic evolution, mapped alteration, hyperspectral response, and the lithogeochemical and C isotope footprints around the Highland Valley Porphyry Cu (HVC) deposits hosted in the Guichon Creek batholith in southcentral British Columbia. The review of the district will focus on the integration of the disparate data sets to better define the extent of the porphyry related hydrothermal alteration. Additionally, we will visit some key surficial geology sites and discus the composition and mineralogy of till and its relationship to dispersion from the porphyry centers.

The volume of hydrothermally altered rocks outboard of economically significant concentrations of Cu-Fe–sulfide minerals is termed the porphyry footprint. An understanding of the fluid types that can be present during porphyry Cu formation, how they manifest in the footprint and their spatial distribution with respect to Cu-mineralized portions of the system is critical to developing better exploration tools. Four major porphyry Cu (± Mo) systems, hosted in various intrusive facies of the Late Triassic calc-alkalic Guichon Creek batholith, occur in the HVC district (Figure 1a). Exposure and airborne magnetic data indicate that the batholith has an oval shape, elongate to the northwest, with a long axis of approximately 60 km and a short axis of 25 km. Due to its size and low degree of exposure (~3%), the HVC district is a realistic natural laboratory in which to investigate the large-scale footprint of porphyry Cu deposits and has been the subject of recent detailed mapping and sampling by the NSERC-Canadian Mining Innovation Council Footprints project. The field review of the district-scale footprint will consist of a traverse of representative outcrops, with accompanying data-sheets, from the margins of the batholith towards Cu mineralization associated with the actively mined porphyry centers. The focus will be on the regional alteration footprint and will not include a mine tour.

Detailed Itinerary

Transportation: Three rental mini-vans will depart from the downtown Vancouver conference center on the morning of the day prior to the field trip (Friday the 22nd of June). Participants will drive to Merritt in the Interior Plateau on

Friday morning for a map review and presentations that afternoon and evening. We will depart to HVC for a full day in the field on Saturday June 23rd and return that evening to stay in Merritt for a second night. Accessing the Guichon Creek batholith on a Saturday is preferred to a week day so as to avoid logging truck traffic. Participants will return to downtown Vancouver on Sunday June 24th, arriving around midday.

Afternoon-Evening Review: After checking in at the hotel in Merritt on Friday, we will gather in a meeting room for a review of the regional and district geology in terms of rock types and structures, geochronology, magmatic evolution, and mapped alteration. The format will be a mix of power point presentations and informal discussion over maps and hand samples.

Tour Day: Starting from the margins of the batholith we will visit exposures of epidote ± prehnite veins with prehnite-white-mica (short-l)-chlorite alteration halos and work our way inwards towards the porphyry deposits stopping at Cu-occurrences that are characterized by high Cu-Ag grades and narrow domains of intense white-mica (long-l) alteration. From approximately 8km south of the porphyry centers we will visit outcrops that have a higher density of prehnite veins with prehnite-white-mica halos ± concomitant carbonate addition that are characterized by magmatic δ13Ctotal values. Additionally, the lithogeochemical and field characteristic of sodic-calcic altered rocks peripheral to the porphyry Cu deposits will be reviewed (Figure 2a). Within 1-3km outboard of the porphyry centers we will see early K-feldspar fracture halos with trace chalcopyrite patina, and fracture and pervasive white-mica (short to intermediate-l)-chlorite alteration associated with weak pathfinder element enrichment. While traversing the batholith, key exposures of overburden (drift) will be reviewed in conjunction with till mineral grain count and geochemical data to compare the response with respect to the porphyry deposits.


  • 30-40 minute hikes (off-trails and some slopes) will be required to visit some exposures
  • Hiking boots, back-packs, and waterproof jackets are required
  • Accommodations in Merritt will be double occupancy
  • Lunch on the field tour day will be provided, but registrants will be responsible for their own breakfast, dinner and other meals in Merritt

$1050 Include: transportation, meals, accomodation and guidebook

All successful geochemical surveys begin with collecting good quality, representative samples that, in turn, rely on in-the-field recognition of appropriate sample media. The geoscientist must identify the landforms (especially in glaciated terrains) from which the media are collected to accurately interpret the source provenance of any anomalous results. This 3-day field trip is for geoscientists who want to learn more about interpreting glacial landforms on macro and micro scales and the sampling of soils, tills, sediments and vegetation. Instruction will be given by leading industry experts in Quaternary geology, biogeochemistry, exploration geochemistry and analytical chemistry. We will engage in sampling techniques designed for defining baseline and anomalous trends employed in environmental and exploration geochemistry on property, reconnaissance and global scales. The field trip will visit two mineral deposits (a reclaimed massive sulphide deposit on the BC mainland and a porphyry Cu-Au prospect on Vancouver Island). In situ analysis of samples using field portable instruments (e.g. pXRF) combined with subsequent lab analyses of collected samples will give the participants a full appreciation of discovering geochemical anomalies and tracing these to mineralization. The field trip will venture though some of the most picturesque landscapes that BC has to offer.

Detailed Itinerary Transportation: Participants will travel via 7 passenger SUVs. All sites are accessible by either paved or all-weather gravel roads. Some sample sites will require short hikes through the bush. Participants will be picked up at 9:00 AM from the conference centre on Friday, June 22 and returned to the conference centre at 8:00 PM on Sunday, June 24.

Day 1 (Friday, June 22) Drive to Britannia Beach located 50 km north of Vancouver to participate in a sampling demonstration of techniques developed by the IUGS Commission on Global Geochemical Baselines using stream and overbank sampling. Subsequently the group will travel to Vancouver Island on board BC Ferries then drive up to Courtenay, BC. Stops will be made to examine large-scale Quaternary geology landforms guided by Travis Ferbey, Quaternary geologist with the BC Ministry of Mines and Petroleum Resources – Geological Survey Branch.

Day 2 (Saturday, June 23) The group will venture to the top of Mt Washington to learn about vegetation sampling from Dr. Colin Dunn the leading world expert on bio-geochemistry. Subsequently, Travis Ferby will help us examine smaller scale Quaternary geology features for determining ice direction and learn about till sampling. The day will wrap up with a demonstration of moss-mat and stream sediment sampling designed for property scale geochemical exploration by Dr. Ray Lett.

Day 3: (Sunday, June 24) The group will engage in a soil sampling program along a mountain road led by Dr. Peter Winterburn, to learn how to interpret the nature of the overburden, what comprises a good sample and the observations needed to interpret results. The afternoon will focus on sampling at the mouth of a drainage basin for bulk sample and heavy mineral surveys employed in reconnaissance surveys by Dr. Ray Lett. The convoy will then return to Nanaimo, BC to catch the ferry back to the mainland and on to Vancouver.


  • 30-40 minute hikes (along rough dirt roads and some slopes) will be required to visit some sample sites. Stream sample sites can be wet; waterproof boots are recommended.
  • Hiking boots, back-packs, and waterproof jackets are required.
  • Accommodation in Courtenay, BC will be double occupancy.
  • All meals will be provided (packed lunches will comprise sandwiches, boxed drinks and fruit).

This one day field trip will take in aspects of the geology of the mountainous north side of Vancouver harbour and will include visits to both the Capilano and Seymour watersheds to understand the Seymour-Capilano Twin Tunnels Projects and tour some of the associated facilities. Completed in 2015, Seymour-Capilano is a major modern urban water handling and treatment scheme that supplies domestic drinking water to 2.4 million local residents, at a rate of 1.8 billion litres per day. The twin tunnels project involved installing two 7.2km tunnels up to 500m below parts of Grouse Mountain to allow a single new filtration plant process water from two distinct watersheds. Leaving downtown Vancouver early in the day and returning late in the afternoon, the trip will commence with a stop at the Cypress Mountain lookout for an overview and review of the geological framework of the Vancouver region. We will then travel to Cleveland Dam on the Capilano River to view some of the key components of the bedrock and surficial geology - this will include a 1.5 hour hike on marked woodland trails with some steep sections and approx. 200 stairs. The afternoon will then be spent on guided tours of Metro Vancouver facilities on the Seymour River including the Seymour Falls Dam, the Seymour Capilano Filtration Plant and Twin Tunnels Portal. Time permitting there may be a stop at the scenic cable suspension bridge spanning Lynn Canyon, a short hike. Coach transportation. Packed lunch provided.

This trip will take participants eastward through the Fraser Valley to the town of Clearwater. During the trip we will be crossing a number of terranes brought together by collision and translation along the continental margin, amalgamating to form the present day British Columbia.  There will be the opportunity to observe the precipitous cliffs, waterfalls and rugged mountains of the Coast Ranges formed of these collisions as the tour climbs through the heart of these mountains.  From Clearwater, the tour will investigate a zone of transition between the Cariboo and Monashee mountain ranges where deep crustal faults have provided pathways for mafic magmas producing the Wells Gray–Clearwater volcanic field. Here, the interaction between volcanism and multiple glaciations over a three million year period have created rugged terrain and other unique subglacial landforms. More than 25 cubic kilometers of lava have poured out and at least 21 eruptive centers have been identified, several of them subglacial landforms called Tuyas. Over the vertical cliffs fall many torrents of water, including Canada’s fourth highest water fall – Helmcken Falls. Participants will have the opportunity for hands-on examination of complex stratigraphy related to volcano-glacier interaction in addition to experiencing stunning views of waterfalls, walking behind a water fall and taking in the surrounding terrain dotted with subglacial landforms. On the afternoon of the third day, the trip will leave Wells Gray and head westward to the town of Lillooet on the might Fraser River. From here, the trip will head southward following the Duffy Lake road with stunning alpine views. Short stops at Nairn Falls (a raging torrent over granite) and Brandywine Falls (a mini Helmcken Falls), are planned with arrival back in Vancouver on the evening of the last day.
