ABSTRACT
This report provides the results from the first year of a multi-year (commenced in 2009) till geo-chemistry and surficial mapping program in northeast Newfoundland, which focused on areas north andeast of Gander Lake (NTS map areas 2D/16 and 2C/13). Regional till sampling was conducted at a spac-ing of 1 sample per 1 km2 in areas of good access, and 1 sample per 4 km2 where helicopter support wasrequired; a total of 496 till samples were collected. Geochemical data of 53 elements, from BC- or C-horizon till samples, is presented and includes the results of analyses by ICP-ES for aluminum, arsenic,barium, beryllium, cadmium, calcium, cerium, chromium, cobalt, copper, dysprosium, iron, lanthanum,lead, lithium, magnesium, manganese, molybdenum, nickel, niobium, phosphorus, potassium, scandium,sodium, strontium, titanium, vanadium, yttrium, zinc and zirconium; by INAA for antimony, arsenic, bar-ium, bromine, calcium, cerium, cesium, chromium, cobalt, europium, gold, iron, hafnium, iridium, lan-thanum, lutetium, mercury, molybdenum, nickel, neodymium, rubidium, scandium, samarium, selenium,silver, sodium, strontium, tantalum, tin, terbium, thorium, tungsten, uranium, ytterbium, zinc and zirco-nium. A complete data listing, field duplicate data, and individual element distribution maps, on abedrock geology base map, are also provided.
The study area is dominated by till, of varying thicknesses, and organic deposits. Inland, the till coveris extensive and it conceals much of the bedrock, creating a gently undulating topography. Toward thecoast, the topography is rugged and till cover is generally thin (or absent) and exposed bedrock promi-nent. Sediment in the Butts Pond area include glaciofluvial and hummocky deposits, esker-like ridges,and a raised marine delta that formed during deglaciation, as the ice was retreating toward GanderLake.
The data from ice-flow mapping showed two regionally extensive events. The earliest ice flow waseastward throughout the field area, likely from a source north of Red Indian Lake. The most recentregional flow was north-northeastward and was only observed in the western part of the study area, theremainder being covered by stagnant ice.
Anomalous concentrations of gold, arsenic, chromium, copper, lead and zinc are present throughoutthe study area, particularly in tills overlying the metasedimentary rocks of Jonathans Pond Formation.
INTRODUCTION
This open file report describes the till geochemistry of the Gander Lake–Gambo (NTS map
areas 2D/16 and 2C/13) area, and supplements the Current Research report of Brushett (2010), a
shortened version of this report. This open file report is the first from a multi-year till geochem-
istry and surficial geology mapping program in northeast Newfoundland that commenced in 2009.
Previous mineral exploration in this area focused on gold and base metals in rocks of the Gander
River complex, and more recent mineral potential identified in areas underlain by quartz-rich
sandstone and quartz breccias of the Gander Group (Evans, 1993). Only limited surficial mapping
has been completed in the field area – in the Gambo area (part of NTS map area 2D/16) by
Vanderveer and Taylor (1987) and McCuaig (2006), and in the Weir’s Pond area (parts of NTS
map areas 2D/16 and 2E/1) by Butler et al. (1984).
Given the presence of mineralization and limited surficial mapping, the objective of this field
program was to further understand the region’s Quaternary geology, as it relates to mineral explo-
ration, and provide a basis for the sound evaluation of the geochemical data; it will identify suit-
able sampling media for further geochemical exploration, especially in the more inaccessible and
drift-covered areas that are common throughout this region.
The results of this project will supplement those from similar projects in surrounding areas,
including the Bonavista Peninsula (Batterson and Taylor, 2001), Grand Falls–Mount Peyton area
(Batterson et al., 1998), Hodges Hill area (Liverman et al., 2000), and Gander area (Batterson and
Vatcher, 1991).
LOCATION, ACCESS AND PHYSIOGRAPHY
The study area is in northeastern Newfoundland and within NTS map areas 2D/16 and 2C/13,
an area of approximately 1260 km2 lying between 53°42' and 54°31'W and 48°47' and 49°07'N. It
extends from the community of Benton in the southwest to Centreville in the northeast (Figure 1).
Access to most of the field area is via paved roads (e.g., Trans Canada Highway (TCH) and Route
320 (Gambo to Wesleyville)) or unpaved logging roads. ATVs were used along approved trails
and the old railway bed; remote areas were accessed by helicopter.
The topography is gently undulating, and glacial cover varies in both thickness and areal dis-
tribution. Gander Lake, the dominant feature, is a long, narrow (40 km long by up to ~3 km wide)
lake reaching a maximum depth of at least 288 m (O’Connell and Dempson, 2002). Hills to the
south of the lake rise to 215 m asl, giving a maximum relief of 503 m for the trough. The steep
sides, shape of the basin and alignment, with known ice-flow directions, are consistent with the
description of fjords of glacial origin (Jenness, 1960).
North of the Gander Lake basin, the topography is typically flat and featureless. Surficial
cover is thin, particularly along the TCH where bedrock is commonly exposed. The area south of
the Gander Lake basin is dominated by a hilly topography and thick sediment cover, hummocky
terrain, boulder fields and rare bedrock outcrops. The topography becomes more rugged toward
the coast where sediment cover generally thins and bedrock is prominent.

The study area has numerous ponds and is dissected by streams that generally drain eastward
into Freshwater Bay. Home Pond drains eastward through a series of ponds to Traverse Pond and
into the bay. Rodney Pond drains eastward through Second Burnt, First Burnt and Square ponds.
Square Pond drains northeastward to Butts Pond, which drains into Freshwater Bay through
Middle Brook.
BEDROCK GEOLOGY
The study area is predominantly within the Gander (tectonostratigraphic) Zone of the
Newfoundland Appalachians (O’Brien and Knight, 1988; Williams et al., 1988), although rocks
of the northwestern Avalon Zone outcrop in the easternmost part of the study area. Much of the
area lies within the Gander Group of the Gander Zone, and comprises a north-northeast-trending
belt of Ordovician metasedimentary rocks of the Indian Bay Big Pond and Jonathans Pond forma-
tions (Figure 2; Blackwood, 1982; O’Neill, 1990). The Indian Bay Big Pond Formation consists
of grey to purple, pebble and cobble conglomerate interbedded with grey quartz-rich sandstone,
maroon siltstone, and greyish-green pelite. The Jonathans Pond Formation consists of interbedded
psammite, semipelite and greyish-green pelite predominantly metamorphosed to greenschist or
amphibolite facies (O’Neill, 1991). The Gander Group grades eastward into amphibolite-facies
rocks of the Hare Bay Pond Gneiss (O’Neill, 1987). Exposures of gabbro and biotite or horn-
blende granite in the Wing Pond, Gull Pond, and Square Pond areas and of ultramafic rock near
Square Pond and Butts Pond are associated with the Wing Pond Shear Zone (O’Neill, 1991).

The Gander Group is intruded by several Devonian-aged granitic plutons, the most extensive
being the Gander Lake granite; a predominantly massive, K-feldspar megacrystic, biotite granite,
which underlies much of the study area south of Gander Lake. Other plutons include a fine-
grained, equigranular, pink- to red-weathering granite with gabbroic intrusions of the Mount
Peyton intrusive suite to the west (Blackwood, 1982), and a medium- to coarse-grained, white- to
pink-weathering, muscovite granite in the Gillingham’s Pond area, which may be correlative with
the Middle Ridge granite to the southwest (O’Neill, 1990).
The Gander Zone is separated from the Avalon Zone in the southeast by a 300–500 m wide
mylonite zone that defines the Dover Fault (Blackwood and Gibbons, 1977). Bedrock in the area
includes Neoproterozoic rocks of the Love Cove and Musgravetown groups. The Love Cove
Group, the oldest rocks in the area, consists of sericite and chloritic schist, associated acidic and
intermediate volcanic lava, strongly foliated pyroclastic rocks, and minor sedimentary rocks. Most
of the area west of Bloody Reach is underlain by the Neoproterozoic Musgravetown Group, which
comprise red and green conglomerate, sandstone, siltstone, red, buff and grey flow-banded rhyo-
lite, and minor rhyolite breccia and tuff (O’Brien and Knight, 1988).
Rocks of the Gander River complex and Dunnage Zone, occurring to the west and south of the
study area, could potentially be used as indicators of glacial transport directions and distances.
The Davidsville Group of the Dunnage Zone comprises Middle Ordovician quartz-poor sand-
stone, siltstone and conglomerates that are non-conformable over the Gander Group.
Conglomerates have not been identified in the Gander Group and are thus considered here to be
a potential useful indicator of glacial transport. The Gander River complex marks the boundary
between the Gander and Dunnage zones and is restricted to a thin north-northeast to south-south-
west belt composed mainly of locally serpentinized pyroxenite, but also includes local exposures
of carbonate, talc, and gabbro (O’Neill, 1990); these clasts are also considered to provide details
on ice-flow history in the area.
Historically, rocks of the Gander River complex have been the main focus of mineral explo-
ration in the area, with gold as the primary target. More recent mineral exploration activity has
been centred in areas underlain by quartz-rich sandstones and quartz breccias of the Indian Bay
Big Pond and Jonathans Pond formations, where gold is the main target of exploration (Evans,
1993). Gravity–magnetic data (Miller, 1988) and lake-sediment survey data (Davenport et al.,1988) indicate a correlation of arsenic, antimony and gold along a gravity–magnetic boundary
which, combined with gold occurrences in the Little Wing Pond showing (O’Neill and Knight,
1988) and the Stallion/Star Track project area east of Benton, suggest further mineral potential.
QUATERNARY HISTORY
QUATERNARY HISTORY OVERVIEW
Previous work on the glaciation of Newfoundland suggests that during the last glacial maxi-
mum (LGM; ~21 ka), the island was covered by multiple coalescent local ice caps extending out
to the continental shelf edge (Grant, 1989; Shaw et al., 2006). The sequence of deglacial events
following LGM are based mostly on striation and landform data, that depict a first-order ice divide
extending south and southeast across the island, along the axis of the Long Range Mountains, east
4
through central Newfoundland and across the Avalon Peninsula (Figure 3). Early ice retreat was
facilitated by calving along deep channels, particularly off northeast Newfoundland. This created
a second-order ice divide along the axis of the Cape Freels peninsula that separated ice flow in
Notre Dame and Trinity basins, where depths greater than 600 m have been reported (Shaw,
2003). Ice retreat continued via calving embayments until ~13 ka when ice margins reached
coastal areas and the configuration of ice divides shifted as deglaciation became land-based;
retreat of isolated ice caps continued by ablation, but predominantly through melting (Shaw et al.,2006). At least fifteen of these remnant ice caps were present at the time (Grant, 1974), five of
which had the potential to influence ice flow in northeastern Newfoundland. These ice caps were
located near Red Indian Lake, Meelpaeg Lake, Middle Ridge, north of Grand Falls (in the Twin
Ponds area) and in the Gander area (Grant, 1974). The Gander area was likely ice-free by ~11.5
ka, based on radiocarbon dates from marine macrofauna found in the lower Gander and Exploits
river valleys (Batterson and Taylor, 1998; McCuaig, 2006).
ICE-FLOW PATTERNS
Paleo ice-flow directions determined from glacial erosional evidence, mostly striations, indi-
cate at least two separate ice-flow events in northeastern Newfoundland during the last, late
Wisconsinan glaciation. Relative age relationships were determined from crosscutting relation-
ships and leeside preservation (Taylor and St. Croix, 1989; St. Croix and Taylor, 1990, 1991;
Batterson et al., 2001).

A total of 64 striations were recorded from 51 sites during the 2009 field survey.
Multidirectional patterns were observed at 10 sites; however, relative age relationships were deter-
mined only at 7 sites. These striations are generally consistent with previously described regional
ice-flow patterns (St. Croix and Taylor, 1990, 1991) and indicate that the study area was affected
by 2 separate ice-flow phases (Figure 4).
Flow Phase 1
The earliest flow was eastward (~ 095° ± 25°) and is found across the entire study area. These
striations are consistent with previously described ice-flow patterns identified in the Gander Lake
area, where ice flow roughly parallels the lake in its central and southeast-oriented portions
(Vanderveer, 1985; Vanderveer and Taylor, 1987; Batterson and Vatcher, 1991; St. Croix and
Taylor, 1991), and eastward toward the coast into Freshwater Bay and the Cat Bay area (Jenness,
1960; Butler et al., 1984; St. Croix and Taylor, 1991). These eastward striations range between 70
to 120°; this variability likely reflects topographic influence as thinning ice was drawn-down
toward the coast. The probable source of this ice-flow event was from north of Red Indian Lake,
based on the presence of eastward striations in the northwest Gander River area (Proudfoot et al.,1988), the Grand Falls–Glenwood area (Batterson and Taylor, 1998), and the Red Indian Lake
area (Vanderveer and Sparkes, 1982).

Two ice-flow phases affected the study area.The first (Flow phase 1) was a regionally extensive eastward flow from a source likely north ofRed Indian Lake. Stagnant ice was likely present in the eastern area for some time and the laternorthward ice-flow phase (Flow phase 2), sourced from the Middle Ridge area, is only recordedin the west part of the study area.
Flow Phase 2
The eastward ice-flow event was followed by a north-northeast ice-flow, evidence for which
is widespread throughout most of northeastern Newfoundland (Butler et al., 1984; Vanderveer and
Taylor, 1987; St. Croix and Taylor, 1990, 1991; Batterson and Vatcher, 1991; Scott, 1994;
Batterson and Taylor, 1998). However, it was only observed in a few sites in the western portion
of the study area (~ 006° ± 014°), where it roughly parallels the southwest Gander River valley
and the Outflow (to the west of the study area), but obliquely crosses Gander Lake. Where stria-
tions related to both the northward and eastward flow are observed, the northward flow is inter-
preted to be the younger of the two, consistent with regional ice-flow relationships recorded to the
west of the study area. The source of this ice flow is likely from the Middle Ridge area (Proudfoot
et al., 1988; St. Croix and Taylor, 1990, 1991).
SURFICIAL GEOLOGY
The area is dominated by varying thicknesses of sediment and lies predominantly within the
‘outer drift zone’ described by Jenness (1960). This zone is characterized by thin till cover, and
valleys containing glaciofluvial sediments derived from melting ice inland. It is separated from an
‘inner drift zone’ by a discontinuous ‘boulder-till moraine’, which generally contains thicker till
cover and has a hummocky or ribbed topography that suggests inland ice stagnated. The bound-
ary of this zone crosses part of the field area to the south of Gander Lake. Jenness (1960) suggest-
ed that this zonation evolved as a result of rapid ice retreat from its terminal position on the north-
east coast to a major stillstand position marked by the moraine.
TILL
Diamicton is the dominant surficial deposit within the study area. There is a marked contrast
between diamictons in the coastal areas and those inland. North of Gander Lake, diamicton cover
is generally thin with numerous bedrock exposures, particularly adjacent to the TCH. In the
Soulis, Home and Gull pond areas, and south of Gander Lake, blankets of diamicton (>2 m) are
common and bedrock exposures are rare (Plate 1). Hummocky terrain is also present south of
Gander Lake. Hummocks commonly have a surface cover of boulders, likely derived from a
supraglacial source. Drumlinoid features and crag-and-tail hills were identified from aerial photo-
graphs and Shuttle Radar Topography Mission (SRTM) data. Orientations of these features, along
with those of isolated crag-and-tail hills, are consistent with the regional eastward striations
observed in the area (Figure 4). In coastal areas, exposed bedrock is dominant, the topography is
more rugged and diamicton occurs as either a discontinuous veneer or is absent (Plate 2).
Few natural sections were observed and only a single stratigraphic unit of diamicton was
noted. Sedimentary structures were not generally noted, but this may be due to poor exposure.
Diamicton texture and colour varies throughout the field area and reflects the underlying bedrock
geology. Diamicton underlain by the Gander Group are commonly light brownish-grey to grey,
whereas diamicton underlain by Gander Lake granite are typically pinkish grey. The matrix is pre-
dominantly silty sand, poorly sorted and slightly- to moderately-compacted. Diamicton, in areas
underlain by Gander Lake granite, has a coarser, sandier matrix than diamicton underlain by the
7
Gander Group. Clasts are granule- to boulder-sized (up to 3 m diameter) and are mostly subround-
ed to angular. Clasts are commonly striated and have thin silt coatings on their upper surfaces.
Clast lithology and shape are controlled by the underlying bedrock. Angular, fragile shale clasts
are common in areas underlain by bedrock of the Gander Group, whereas granite clasts are gen-
erally subrounded. Clast content varies between 30 and 70 percent, averaging about 55 percent.
South of Gander Lake, boulders 1 to 3 m diameter are common on and near the diamicton surface.
The characteristics described above (subrounded clasts, striated and fragile clasts, and silt
coatings) are interpreted to represent deposition as subglacial melt-out till (Dreimanis, 1988).
These sediments are commonly associated with stagnating glaciers. Detailed clast fabric analysis
and examination of the stratigraphy, to be conducted in future work, will provide further details
on the depositional environment.
GLACIOFLUVIAL–GLACIOMARINE–MARINE SEDIMENTS
Thick deposits of ice-contact and ice-proximal sediments were produced by meltwater from
receding ice at the eastern end of Gander Lake and eastward through Butts Pond and Gambo into

Freshwater Bay (Butler et al., 1984; McCuaig, 2006). These deposits include 4 geomorphic units
representing 4 depositional environments:
• a zone of hummocky glaciofluvial sediments containing an abandoned meltwater channel
at the eastern end of Gander Lake;
• braided river sediments to the southeast of the hummocky zone consisting of poorly- to
moderately-sorted gravel/boulder beds with some crossbedding;
• an esker complex at Butts Pond, consisting of a series of sinuous features made up of
mainly poorly sorted, large (up to ~3 m in diameter), subrounded in a fine sand to cobble
gravel matrix; and
• deltaic sediments extending from Butts Pond to Gambo, consisting of planar to undulating
deposits containing predominantly sandy beds (Figure 5; McCuaig, 2006).
McCuaig (2006) suggested that these four depositional environments were part of a glacial
spillway where meltwater flowed eastward into Freshwater Bay from westward-retreating ice. The
elevation of the delta topset beds was at 43 m, providing a marine limit for the area. Ground-pen-
etrating radar (GPR) profiles taken seaward of the delta show reflections that are consistent with
Gilbert-type deltas (McCuaig, 2006). The elevation of topset beds in the GPR profiles is 30 m,

suggesting that the delta began to develop at 43 m asl and the 30 m topset beds formed as the delta
adjusted to sea level fall.
The coastal region of the study area likely had a type-B sea-level curve, characterized by rapid
sea-level fall to below modern sea level followed by slower sea-level rise to present. Sea level fell
below present between 10 and 9.5 ka (Liverman, 1994).
Age constraints on the deglaciation within the study area come from radiocarbon dates on
marine macrofauna (Hiatella arctica) found in silty clay near the shore of Gander River, approx-
imately 15 km northeast of the northern outlet. These dates indicate that ice had retreated from
this area and was open to the sea by approximately 12.2 ka (McCuaig, 2006).
ORGANIC DEPOSITS
Organic deposits, common within the study area, are generally associated with poorly drained
areas. Numerous bogs are found in valleys along the coast, low-lying areas in the interior of the
region and in depressions associated with hummocky moraine.

SUMMARY OF GLACIAL HISTORY
The study area was covered by glacial ice from two sources during the last, late Wisconsinan
glacial period. The first ice-flow event was a regional eastward flow that extended into Bonavista
Bay. This ice flow is recorded across much of northeast Newfoundland and likely had a source
area north of Red Indian Lake (Vanderveer and Sparkes, 1982; Proudfoot et al., 1988; Batterson
and Vatcher, 1991; St. Croix and Taylor, 1990, 1991; Scott, 1994).
The eastward ice-flow event was followed by a north to northeastward ice-flow, likely sourced
from the Middle Ridge area (Rogerson, 1982). The eastern portion of the study area showed no
evidence of a northward ice flow and was likely covered by stagnant ice; this is supported by hum-
mocky moraines at the eastern end of Gander Lake, hummocky topography south of Gander Lake,
and esker-like ridges near Joe Batt’s Brook and Fox Pond. This is in agreement with a remnant ice
centre postulated by Grant (1974). The area became ice-free sometime before 12.2 ka based on
shells from the Gander River valley (McCuaig, 2006).
REGIONAL SURFICIAL SEDIMENT SAMPLING
SAMPLING AND SAMPLE PREPARATION METHODS
Till sampling, conducted using the surficial geology as a guide, resulted in 496 samples
(including duplicates) being collected from the C- and BC-horizons; most were from test pits (40
to 60 cm depth) and roadcuts (50 to 100 cm depth). Mudboils were sampled at shallower depths
(average 25 cm). In rare cases, where there was a lack of surface sediment, samples were collect-
ed from bedrock detritus. Marine and fluvial or glaciofluvial sediments were avoided during sam-
pling, because of the possibility of reworking and the difficulty in defining distances and direc-
tions of transport. Sample spacing was controlled by access as well as surficial geology, but was
generally about 1 sample every 1 km2 in road accessible areas, and every 4 km2 in more remote
areas where helicopter support was required. Duplicate samples were taken from 30 sites and were
used to test for field reproducibility.
Data from 466 samples are presented (Figure 6), excluding the field duplicates. In the field,
samples were placed in kraft-paper sample bags, and sent to the Geological Survey’s Geochemical
Laboratory in St. John’s, where they were air-dried in ovens at 40°C and dry-sieved through 180
μm stainless steel sieves.
GEOCHEMICAL ANALYSES
Analytical work was carried out at the Geological Survey’s Geochemical Laboratory, and
additional analyses from a commercial laboratory. The appended data listings contain all the field
and analytical data from the sediment survey. To distinguish the different analytical methods/lab-
oratories, the trace-element variables are labelled with a combination of the element name, a
numeric code and the unit of measurement. A complete list of variables is given in Table 1, and a
full listing of field and geochemical data is contained in Appendix A.

ANALYTICAL METHODS
Gravimetric Analysis (LOI)
Organic carbon content was estimated from the weight loss-on-ignition (LOI) during a con-
trolled combustion in which 1g aliquots of sample were gradually heated to 500°C in air over a 3
hour period. Accuracy can be judged from the results for reference materials (Table 2).
Inductively Coupled Plasma-Emission Spectrometry (ICP-ES)
For these analyses, the procedures outlined by Finch (1998) are followed. One gram of sam-
ple is weighed into a 125 ml Teflon beaker, and 5 ml of concentrated HCl and 5 ml of perchloric
acid is added to each sample. The samples are placed on a hotplate at 200°C and evaporated to
dryness, after which the beakers are half-filled with 10 percent hydrochloric acid and returned to
the hotplate at 100°C. When the residue is completely dissolved the samples are removed, cooled
and transferred to 50 ml volumetric flasks. One ml of 50 g/l boric acid is added to each sample to
remove any residual hydrofluoric acid. The samples are made to volume and analyzed by ICP-ES
(Licthe et al., 1987). For most elements dissolution is total; exceptions are Cr from chromite, Ba
from barite and Zr from zircon. Accuracy can be judged from the results for reference materials
(Table 2). Values for the following elements were determined: aluminum, barium, beryllium, cal-
cium, cerium, cobalt, chromium, copper, dysprosium, iron, gallium, potassium, lanthanum, lithi-
um, magnesium, manganese, molybdenum, sodium, niobium, nickel, phosphorus, lead, scandium,
strontium, titanium, vanadium, yttrium, zinc and zirconium (Al2, Ba2, Be2, Ca2, Ce2, Co2, Cr2,
Cu2, Dy2, Fe2, Ga2, K2, La2, Li2, Mg2, Mn2, Mo2, Na2, Nb2, Ni2, P2, Pb2, Rb2, Sc2, Sr2, Ti2,
V2, Y2, Zn2 and Zr2, respectively).
Instrumental Neutron Activation Analysis (INAA)
These analyses were carried out at Becquerel Laboratories, Mississauga, Ontario. On average
24 g of sample was used for analysis and the samples (with duplicates and control reference mate-
rials included incognito) were weighed and encapsulated in the Geochemical Laboratory of the
Department of Natural Resources in St. John's. Samples were irradiated with flux wires and an
internal standard (1 for 11 samples) at a thermal neutron flux of 7 x 1011 n/cm2s. After 7 days (to
allow Na24 to decay), samples are counted on a high purity Ge detector with a resolution of better
than 1.7 KeV. Using the flux wires, the decay-corrected activities are compared to a calibration
developed from multiple certified international reference materials. The standard present is only
a check on accuracy of the analysis and is not used for calibration purposes. Ten to 30 percent of
the samples are checked by re-measurement. Accuracy can be judged from the results for refer-
ence materials (Table 3).
Total contents of the following elements were determined quantitatively: silver, arsenic, gold,
barium, bromine, calcium, cerium, cobalt, chromium, cesium, europium, iron, hafnium, mercury,
iridium, lanthanum, lutetium, molybdenum, sodium, neodymium, nickel, rubidium, antimony,
scandium, selenium, samarium, tin, strontium, tantalum, terbium, thorium, uranium, tungsten,
ytterbium, zinc and zirconium. (Ag1, As1, Au1, Ba1, Br1, Ca1, Ce1, Co1, Cr1, Cs1, Eu1, Fe1,

QUALITY CONTROL
Data quality was monitored using laboratory duplicates (analytical precision only). These data
are verified at the laboratory and are not included in this report, although they are available upon
request. Accuracy estimates are provided by the results from standard reference materials
analysed with them (Tables 2 and 3). These data show that for almost all elements, with Zr2 as an
exception, all data is of high quality.
Data from duplicate samples taken from the same site are presented in Table 4. The extent of
correlation (Pearson) of these data provided a measure of data reproducibility which was used to
estimate data quality. Identical results of duplicate samples show a correlation coefficient of 1.000.
For some elements, the analysis of duplicates yields poor correlations, commonly because samples
contain levels that are close to the detection limit for that element. Most samples yielded results
below detection limit for Ag1, Cd2, Eu1 and Se1, and for this reason it is difficult to evaluate data
quality for these elements.
It should be emphasized that for mineral exploration, the relative variation of an element is of
primary concern. Of the 46 elements determined, 12 were determined by both ICP-ES and INAA
(As, Ba, Ce, Co, Cr, Fe, La, Mo, Na, Rb, Sc, Zr). To reduce the size of the data for presentation
and statistical analysis, for these 12, the data from the method with the best quality determined
from comparison with laboratory and field duplicates have been used (i.e., As1, Ba1, Ce2, Co2,
Cr1, Fe2, La2, Mo2, Na2, Rb2, Sc2, Zr2), although all are presented in the data listing (Appendix
A). A summary of field duplicate and control data is included in this report, and detailed data are
available on request.
STATISTICAL ANALYSIS–FREQUENCY DISTRIBUTIONS
The frequency distributions of the geochemical data were examined using the Jenks optimiza-
tion method, also known as the goodness of variance fit (Jenks, 1967) found within the ArcMap
GIS application. The method identifies natural breaks in the dataset, and has replaced the selec-
tion of breaks using cumulative frequency plots (Batterson and Taylor, 2001). Comparison of the
two methods produced similar subdivisions of the data. Breaks in slope of the curves were used
to subdivide the element values into 4–6 natural population groups. These groups are represented
by symbols that increase in size with increasing element levels, and are shown in Figures 7 to 14.
Statistics (maximum, minimum, median, mean, standard deviation) were generated from the
Excel computer application, and are presented in Table 4. Correlation coefficients for laboratory
and field duplicate data are provided in Table 5. A correlation matrix is shown in Table 6.
INTERPRETATION OF GEOCHEMICAL DATA

are described below. Ytterbium, a light rare earth, was chosen to represent the rare-earth elements
(other rare earths are not discussed here but most have similar patterns of background and elevat-
ed values) given the recent increased interest in rare-earth elements elsewhere in the province. As
a means of comparison, geochemical data for selected elements is compared against existing geo-
chemical data for the province found within the Geoscience Atlas (http://gis.geosurv.gov.nl.ca/).Using the Jenks optimization method within the ArcMap GIS application (described above), ele-
ment values were divided into 5 population groups: background, slightly elevated, elevated, very
elevated, and high.
Other element plots are presented in Appendix B. The following is a preliminary interpreta-
tion. Data on mineral occurrences is found within the Geological Survey’s Mineral Occurrence
Data System (MODS) (http://gis.geosurv.gov.nl.ca/mods/mods.asp).
ARSENIC (As)
Approximately 40 percent of the arsenic values identified in till samples are slightly (> than
10 ppm) to very elevated (up to 295 ppm, Figure 7). The highest arsenic values (161, 200 and 295
ppm) are found in till overlying the metasedimentary rocks of the Gander Group, two of which
are adjacent to the Wing Pond Shear zone.
Arsenic has often been considered a pathfinder for gold in geochemical exploration. In this
study, the spatial distribution of arsenic is not consistent with that of gold and there is only a low
correlation between arsenic and gold (0.25). Arsenic is moderately correlated with cobalt (0.47),
chromium (0.39), copper (0.48), iron (0.44), magnesium (0.34), manganese (0.44), nickel (0.45),
and antimony (0.36) (Table 6). Field and laboratory duplicates showed a high degree of correla-
tion, and the data is thus considered accurate and precise (Table 4).
Arsenic is also a factor in human health. The Canadian soil quality guidelines indicate values
below 12 ppm are acceptable for residential use. There are no known mineral occurrences of
arsenic in the study area. About 26 percent of the data points are above this value within the study
area, and occur mostly in till overlying metasedimentary rocks of the Gander Group. Elevated
arsenic levels have also been documented in well water throughout the Gander area; details of this
study are discussed in Serpa et al. (2009).
GOLD (Au)
The gold in till data is difficult to interpret, and it shows a spotty distribution (Figure 8). The
small (<1 kg) sample is likely a factor and caution must be exercised when interpreting anomalies,
due to the ‘nugget effect’.
Approximately 4 percent of the gold values are slightly elevated to elevated (8.4 to 57 ppb).
The highest values are scattered throughout the study area, but mostly occur in till overlying
metasedimentary rocks of Jonathans Pond Formation. The highest gold value recorded was 57
ppb, located near the western end of Home Pond (sample 7262, Figure 12). Known gold show-
ings near the Benton area do not appear to be reflected in the till geochemistry (Startrack and

Stallion prospects; Mineral Occurrence Data System 002D/16/Au001 and 002D/16/Au002). Gold
is poorly correlated with all other elements analyzed (Table 6). Laboratory duplicates showed a
low degree of correlation (-0.025, Table 4).
CHROMIUM (Cr)
The highest chromium value is 920 ppm (sample 7269), part of a cluster of very elevated
chromium values (490 to 920 ppm) found southeast of Jonathan’s Pond (Figure 1), where high
nickel values were also recorded (Figure 9).
Chromium correlates moderately to well with copper (0.50), europium (0.35), iron (0.77),
lithium (0.42), magnesium (0.78), manganese (0.42), nickel (0.84), scandium (0.50), and vanadi-
um (0.74), vanadium (0.73), and zinc (0.49) (Table 6). Field and laboratory duplicates showed a
high degree of correlation (Table 4), and the data is considered accurate and precise.
COPPER (Cu)
Anomalous levels of copper in till (>26 ppm) are common throughout, particularly in till over-
lying metasedimentary rocks of the Jonathans Pond Formation (Figure 10). The highest copper
value recorded was 153 ppm in the area east of Soulis Pond (Figure 1; sample 7260). This sam-
ple is part of a cluster of slightly elevated to elevated copper values ranging from 40 to 153 ppm.
Elevated copper values were also found southeast of Jonathan’s Pond (Figure 1).
Copper correlates moderately to well with arsenic (0.48), cerium (0.65), cobalt (0.73), iron
(0.58), magnesium (0.61), manganese (0.59), and nickel (0.69) (Table 6). Field and laboratory
duplicates showed a high degree of correlation (Table 4), and the data is considered accurate and
precise.
LEAD (Pb)
Approximately 26 percent of the data have anomalous values of lead (>15 ppm). The highest
lead values is 276 ppm (sample 7390), associated with one anomalous value in till overlying
bedrock of the Musgravetown Group (Figure 11). Approximately 4% of the data are elevated to
very elevated with values above 34 ppm; the distribution of the highest lead values is non-clus-
tered. No lead occurrences have been identified in this area.
Lead is moderately- to well-correlated with cerium (0.35), cobalt (0.28), iron (0.28), magne-
sium (0.36), strontium (0.35), and zinc (0.82) (Table 6). Field and laboratory duplicates showed a
high degree of correlation (Table 4), and the data is considered accurate and precise.
NICKEL (Ni)
Approximately 25 percent of the data have anomalous levels of nickel (above 26 ppm). The
highest nickel value is 117 ppm (sample 7390), associated with till overlying bedrock of the
Musgravetown Group (Figure 12). A cluster of elevated nickel values (58 to 115 ppm) occur in till

overlying the Jonathans Pond Formation southeast of Jonathan’s Pond and in the Soulis Pond area
(Figure 1). There are no known nickel occurrences in this area.
Nickel is moderately- to well-correlated with arsenic (0.45), cerium (0.49), cobalt (0.83),
chromium (0.84), copper (0.69), iron (0.69), lithium (0.44), magnesium (0.86), manganese (0.57),
scandium (0.61), vanadium (0.53), and zinc (0.59) (Table 6). Field and laboratory duplicates
showed a high degree of correlation (Table 4), and the data is considered accurate and precise.
YTTERBIUM (Yb)
Anomalous ytterbium values (>9.5 ppm) are scattered throughout the study area. The highest
value is 56 ppm (sample 7387), associated with till overlying bedrock of the Musgravetown Group
(Figure 13). Elevated ytterbium values (>23.2 ppm) occur in several small clusters in till overly-
ing bedrock of the Musgravetown Group (25 to 56 ppm), Hare Bay Gneiss (34 to 37 ppm) and
Gander Lake granite (25 to 28 ppm).
Ytterbium is slightly- to highly-correlated to calcium (0.32), cobalt (0.42), copper (0.43), mag-
nesium (0.41), manganese (0.48), nickel (0.28), phosphorus (0.44), and iron (0.38). It is also cor-
related to other rare-earth elements: cerium (0.68), dysprosium (0.93), europium (0.51), niobium
(0.23), lanthanum (0.62), lithium (0.24), scandium (0.28), strontium (0.48), samarium (0.23), and
terbium (0.53) (Table 6). Field and laboratory duplicates showed a high degree of correlation
(Table 4), and the data is thus considered accurate and precise.
ZINC (Zn)
Approximately 25 percent of the data have slightly elevated to elevated zinc values (54 ppm
to 138 ppm); the distribution of these values is non-clustered. One highly elevated zinc value of
910 ppm (sample 7390) was recorded in till overlying rocks of the Musgravetown Group (Figure
14). No known zinc occurrences have been identified in the study area.
Zinc is moderately- to well-correlated with barium (0.40), cerium (0.25), hafnium (0.31), lan-
thanum (0.28), lutetium (0.39), niobium (0.37), scandium (0.25), terbium (0.34), and ytterbium
(0.43) (Table 6). Field and laboratory duplicates showed a high degree of correlation (Table 4),
and the data is considered accurate and precise.
SUMMARY
The study area has evidence of two Late Wisconsinan ice-flow events. The first was a region-
al eastward flow that extended into Bonavista Bay. This flow is recorded across much of north-
east Newfoundland and likely had a source area north of Red Indian Lake (Vanderveer and
Sparkes, 1982; Proudfoot et al., 1988; Batterson and Vatcher, 1991; St. Croix and Taylor, 1990,
1991; Scott, 1994). The eastward ice-flow event was followed by a north to northeastward ice-
flow, likely sourced from the Middle Ridge area (Rogerson, 1982). The northward flow is only
present in the western portion of the field area. East of this area no striation or landform evidence
of the northward flow is observed. Till occurs mostly as a veneer where hummocky and bouldery

terrain are common, likely formed by a stagnating remnant ice centre, previously postulated by
Grant (1974). Landform evidence supporting the presence (and possible extent) of stagnant ice
includes hummocky moraine at the eastern end of Gander Lake, hummocky topography south of
Gander Lake, and esker-like ridges at the eastern end of Gander Lake, Joe Batt’s Brook, and Fox
Pond. The area became ice-free sometime before 12.2 ka (11.3 cal years BP) based on shells from
the Gander River valley (McCuaig, 2006).
Interpretations of till geochemistry and the development of mineral exploration strategies
should consider the following:
1. Despite the presence of two ice flows, only one till unit was observed, although it should
be noted that fieldwork was limited to natural exposures up to 2 m thick, and separate till
units may be found at depth, in areas of thick till. Based on striation and glacial landform
evidence, the regional eastward ice-flow event was the dominant ice-flow event to have
affected the area.
2. Evidence for northward ice flow is present in the westernmost portion of the study area.
West of the study area, evidence of northward flow is more prominent and two ice-flow
directions should be taken into account for mineral exploration purposes (St. Croix and
Taylor, 1990, 1991; Batterson and Vatcher, 1991; Scott, 1994). Future till sampling and
surficial mapping in areas to the west and north of the study area, conducted in the 2010
field season, should help to resolve the extent of the northward flow and the dominant ice-
flow direction to be considered in future mineral exploration strategies.
3. Sampling in glaciofluvial, fluvial and marine settings should be avoided due to the possi-
bility of sediment reworking, and the difficulty in defining distances and directions of
transport. These areas include the Butts Pond–Gambo area, valley bottoms and areas
below the 45 m marine limit.
4. Hummocky deposits south of Gander Lake likely formed in a stagnating glacial environ-
ment and may contain a greater proportion of supraglacial (and more far travelled) sedi-
ment then basally-deposited till and less likely to be representative of the underlying
bedrock.
