This
report summarizes all the previous exploration work on the Sandspit Gold
property and recommends a program of further geological mapping, geophysical
surveys and contingent diamond drilling to further evaluate the ground. It also documents the results of a short
geological mapping, prospecting and trail building program conducted in July
1997.
The
Sandspit Gold property has the potential for the discovery of a large, bulk
mineable epithermal gold deposit similar to Misty Mountain Gold Ltd.’s
“Speconga Deposit” which is 40 km (25 miles) north. Misty Mountain has announced plans to complete a bankable
feasibility open pit study in 1998 aimed at putting the ore zone into
production. Recent estimates include
the ore body contains 7-8 million tons averaging 0.1 ounces gold per ton or 28
million tons 0.061 ounces gold per ton.
The Specogna Deposit hosts a geological resource of over three million
ounces of gold contained in 59 million tonnes with an average grade of
1.66g/tonne Au. It is still open to the
north west and to depth with excellent potential to develop additional
reserves.
The
Sandspit Gold property is located along the Sandspit Fault, a major crustal
structure that is an important ore-control at the Specogna Deposit. Drilling to date at the Sandspit Gold
property has encountered grades of 0.096 oz/ton over 9.31 metres with selected
samples assaying up to 0.43 oz/ton within a 700 metre by 400 metre target area
defined by arsenic soil geochemistry and magnetic anomalies. Gold mineralization appears to be deposited
in an epithermal environment and further drilling and trenching is required to
determine its’ extent. A rock float
sample was discovered in 1988 (Hepp, 1988) along Copper Bay Creek which assayed
0.268 oz/ton Au, 0.34% As, 0.15% Sb and 5.9 ppm Ag, which is located 3 km south
of the Baxter zone.
Over
$300,000 has been spent to date on the Sandspit Gold Property on detail
geochemical, geological, geophysical, trenching and limited diamond drilling.
LOCATION
AND ACCESS![]()
The
Sandspit Gold property is located along the east coast of Moresby Island,
immediately south of Sandspit. Gold
showings on Baxter Creek, near the centre of the claim group, are at 53o12’N,
131o47’W (103G/4W).
The
property straddles the Sandspit Fault, a crustal structure of regional extent
striking approximately 325°
Az. A pronounced scarp 75 metres (250
ft) high marks the fault line. East of
the fault, topography is flat to the sea and overburden is likely deep (+100m);
west of the fault, low rounded hills reach a maximum elevation of 120 metres
(400 ft). Second growth hemlock and
cedar and dense undergrowth of salal and alder blanket the property.
The
claim area is outside of any area currently being considered for preservation
as a national or provincial park. The
proposed South Moresby Park is 50 km (30 miles) to the south.
A
good gravel road from Sandspit along the base of the Sandspit Fault scarp
provides ready access onto the claims by driving 6.3 km south of the golf
course. The Baxter Creek turnoff is
100m past the Sandspit Rod & Gun Club rifle range. A local bulldozer tote trail leads to the
main interest area on Baxter Creek.
Overland walking is sometimes difficult due to dense undergrowth of
alder and salal and thick second growth hemlock and cedar trees.
Sandspit,
with a population of 600, is a distribution centre and staging point for the
Queen Charlotte Islands. It has
scheduled daily jet service from Vancouver, good hotel/motel accommodations,
heavy equipment contractors and adequate service and supply outlets. Water and Hydro supplied electric power are
locally available.![]()
CLAIMS STATUS![]()
The
Sandspit Gold property is held by eight two-post claims as shown in Table 1 and

Mineral
rights are acquired in British Columbia via the Mineral Act and
regulations. Assessment work is
required each year in the amount of $100 per year per unit for the first three
years and $200 per unit over 3 years.
The
area covered by the Sandspit gold property was first staked in 1969 as the
Airport and IXL Claim Groups by Falconbridge Nickel Mines Ltd. (Band and McDougall, 1970) and Texas Gulf
Sulfur Company (Newell and Delancy, 1970).
These properties covered a prominent limonite stain zone extending along
the trace of the Sandspit Fault, a small Tertiary quartz diorite plug intruding
Jurassic volcanic rocks and high copper/molybdenum sediment values originating
in creeks cutting the fault line scarp.
The companies were exploring for Cu-Mo deposits and conducted grid
sampling which delineated a long, narrow, copper soil anomaly of 70-220 ppm
extending intermittently for over 2 miles along the Sandspit Fault trace
(Assessments Reports 2343, 2777). The
Airport and IXL claims were allowed to lapse with no significant follow-up work
being done.
R.E.
Mickle staked the area as the SNOW claims in January 1979 and subsequently
discovered three separate mineral occurrences including barite veins, a gold
bearing outcrop assaying greater than 0.2 ounces/ton, and an area of Cu-Zn-Pb
carbonate veinlets in volcanic rocks.
The gold was found by trenching on a highly anomalous soil sample (400
ppb Au) in an area of no surface outcrop. (Mickle, 1979)
Falconbridge
Nickel optioned the claims and conducted further trenching in the Baxter Creek
area followed up by drilling three short holes in 1980. Gold was shown to occur in structural zones
within lapilli tuff and tuff breccia of the Yakoun Formation in association with
locally intense silicification. At one
trench location a braided fault in bedrock also cuts the clay overburden. The fault gouge assayed 9.21 oz/ton gold. These results were interpreted by Burns
(1980) to indicate a young, post glacial
age for the mineralized fault system at Baxter Creek, probably representing
a reactivated splay of the main Sandspit Fault which is 100 metres east.
Grab
and selected rock samples from Falconbridge trenches by McDougall showed a
direct correlation between gold and arsenic as shown in Table 2.

The
three drill holes were unsuccessful, totaling only 17 metres (54 feet) with
core recovery of 4-20 percent in faulted zones and 45-75 percent in the
volcanics. No significant gold values
were obtained.
In
1981, Falconbridge conducted detailed soil sampling on three small grids
(Downing, 1981). Samples were at 25
metre intervals along lines 50 metres apart.
On the Baxter Creek Gold Grid 295 samples were analyzed for Au, As, and
Hg. Four backhoe trenches were dug in
the vicinity of anomalous As and Hg values in soil pits. Chip samples of outcrops and in trenches
returned low gold values, the best being 0.072 oz/ton over 3 metres, 0.011
oz/ton over 3 metres and 0.015 oz/ton over 1 metre in Trench 1. Falconbridge concluded that anomalous gold,
arsenic and mercury geochemical values in soil samples possibly reflect weakly
mineralized fault zones and subsequently dropped their option on the property.
The
SNOW property was optioned by Ventures West Minerals Ltd. in the spring of 1981
who conducted a comprehensive grid soil sample program for arsenic as a
pathfinder for gold (Christie and Richards, 1982). 568 soil samples were obtained using a 42 inch auger at 50 metre
intervals along lines 400 metres apart.
In many areas, the ubiquitous organic overburden was too thick to be
penetrated by the auger. Arsenic
greater than 30 ppm was obtained in 22 samples over an area 700m by 500m
encompassing the Falconbridge trenches south of Baxter Creek. The anomaly is considerably stronger and
larger than that obtained by Falconbridge in the same area which is probably a
result of getting deeper samples by auger methods.
A
second smaller arsenic anomaly occurs 3 km to the north of Baxter Creek and is
labeled “Lornex H Grid”. The anomaly is
not well defined because of widely spaced soil lines.
Marjorem
Minerals Inc., a successor company to Ventures West, conducted a small soil and
ground magnetic survey over the Baxter Creek soil anomaly in 1983 (Christie and
Howell, 1984 and a 145 km airborne magnetic and electromagnetic survey in 1985
(Pezzott and White 1984).
The
airborne survey was done at a flight line spacing of 200 metres. According to Pezzott, “The magnetic data
contains a very strong, well defined magnetic high which strikes
northwest-southeast across the centre of the property. The zone is approximately 1.5 km wide and
roughly outlined by the 56,700 gamma contour.
The anomaly reaches highs of 57,400 gammas at its’ central core. Background magnetic intensities to the
northeast lie below 56,300 gammas whereas to the southwest they are slightly
higher, around 56,600”. Pezzott
interprets that the magnetic high indicates the regional extent of a Cretaceous
pluton, however this interpretation conflict with mapping which shows large
areas of Yakoun volcanics within the magnetic high.
The
magnetic pattern appears to be effected by structure. the northeastern flank of the main anomaly “is delineated by a
very sharp magnetic gradient which directly correlates with the geologically
defined Sandspit Fault on the SNOW 3 claim.
Discontinuities are observed along the gradient which strongly suggest
that the major Sandspit Fault has itself been displaced by more recent cross
faulting .... The southwestern flank of
this trend does not exhibit the extreme gradients observed to the north but may
be fault controlled as well.” (Pezzott,
1984).
The
Baxter Creek gold area is within the magnetic high defined by the airborne
survey. At Baxter Creek, a cross fault
at 070o, coincident with mineralized fracture systems, offsets the
magnetic anomaly right laterally about 200 metres. The soil anomaly is near the intersection of the Baxter Creek
cross fault with the Sandspit Fault.
The
northern soil anomaly is located at the intersection of a N-S fault interpreted
from the magnetic data, with the Sandspit Fault system.
Airborne
EM data did not reveal any distinctive anomalies. This would indicate that mineralization is generally disseminated
rather than massive and not conducive to forming highly conductive zones.
For
the Marjorem ground magnetic survey of the Baxter Creek area, a small grid
totaling 3.5 km was installed with lines 500 metres in length at 100 metre
spacing. “A local magnetic low area was
found adjacent to known mineralization.
The low may be part of a zone of lower N-S trending magnetic response
suggested by the survey. The limited
extent of the survey does not allow this to be conclusively demonstrated” (Christie and Howell, 1984). The north-south magnetic low trend may
reflect a fault zone or hydrothermal altered rock.
Auger
soil sampling was done along three lines at 25 metre intervals. Gold values in the soils ranged up to 2670
ppb. Soil anomalies in arsenic and gold
were obtained on all lines over several consecutive samples. Arsenic values are strongly anomalous and
more consistent from sample to sample than gold due to greater mobility in the
natural environment. Line to line
correlation is impossible because of the wide spacing between lines. The gold/arsenic soil anomaly is 100 metres
wide at least 400 metres long, and is open to the south. On line 3+00W, anomalous gold/arsenic soil
correlates well with a local magnetic high.
The
Marjorem survey demonstrated the utility of detailed magnetic and soil surveys
in the Baxter Creek area but the survey itself was not detailed enough to
provide definitive interpretations of the major mineral trends. The widespread occurrence of arsenic/gold in
the soil encompassing the two areas were gold in shear zones is known to occur
is strong evidence of the presence of gold mineralization over a broad area.
Marjorem
let their option expire in 1985 in spite of encouraging results and Lornex
Mining Corporation Ltd. acquired an option in the same year. Lornex did 379.9 metres of diamond drilling
on the Baxter Creek zone and to the north along the Sandspit Fault scarp, plus
additional rock and soil sampling in other areas. Five holes were drilled along a 350 metre linear trend in the
Baxter Creek area. Holes 1 and 3
intersected significant gold values up to 0.146 oz/ton and 0.112 oz/ton
respectively. Hole 1 intersected 0.096
oz/ton gold over 9.31 metres (30.5 ft).
Gold mineralization is accompanied by silicification and clay-sericite
alteration of feldspar in lapilli tuff with pyrite and pyrrhotite up to 10
percent.
Lornex’s
regional work including rock and soil sampling provided no new definitive
anomalies elsewhere. Lornex put in a
small soil grid (500m x 900m) to cover an area of Marjorem soil and magnetic
anomalies (H Grid). The sampling failed
to corroborate the anomalous arsenic results reported by Christie and Richards
(1982). Soil sampling was done by
mattock and may not have been deep enough to yield good samples for arsenic or
gold values.
Lornex
let their option lapse in 1985. up to
the end of Lornex’s involvement, a total of $190,000 was recorded for
assessment purposes.
Mondavi
Resources Ltd. obtained an option from R.E. Mickle in May, 1987 and conducted a
comprehensive program of mapping, geochemistry, induced polarization and
2629.11m of diamond drilling under the direction of B.D. Fairbank, P.Eng. in
1987 and 1988 bring the total exploration expenditures to over $300,000.
Detailed
geological mapping, follow up geochemistry and Induced Polarization indicated
that the mineralized zone continued to the west. Diamond drilling, in 1988, extended the gold zone 400 feet to the
west in holes 11 & 12 as follows:

By
means of Shiel’s Contracting Ltd. of Sandspit, B.C., approximately 600 m of
preexisting access roads have been corduroyed, 525mm of trenches have been back
filled and 6 drill pads have been built using a 235 Road Builder excavator. For geochemical sampling purposes, the
Baxter Creek Area grid had been extended to the N-W; a 600m long bare line has
been cleared and 2775m of cross-lines have been flagged at 25m intervals. Assay results for 102 of the total 138 soil
samples taken at the Baxter Creek Grid extension reveal weakly anomalous Au/As
values trending south westwardly beyond the grid extension. A total of 5 heavy mineral samples taken
within Baxter Creek reveal no significantly anomalous Au/As values.
A
nearby gold property along the Sandspit Fault is the Harmony gold project of
Misty Mountain Gold Limited. During
1996 Misty Mountain Gold Limited significantly advanced its 100% owned harmony
Gold Project towards the goal of having sound environmental stewardship lead to
successful permitting of a substantial gold mine development. This was achieved through exploration and
pre-development expenditures totaling $5.84 million on a systematic core
drilling program of the Specogna Deposit and the advancement of a wide spectrum
of scoping study options to define the Harmony Gold Project. Positive program results are indicating that
in the months ahead an economically attractive gold mine proposal can be
advanced for the Specogna Deposit which will mitigate environmental risks and
maximize benefits for communities in the region.
Forestry
is the main industry on the islands and the largest operators are MacMillan
Bloedel (Graham Island) and TimberWest Products (Moresby Island). Fishing is important to commercial and
recreational operators and is a significant traditional activity of the
Haida. Government and tourism services
account for the other main business activities. Recently, both the forestry and fishing industries on Graham
Island have declined. At the same time,
the former largest employer on the Islands, the Canadian Department of Defense,
has closed down its operations with a loss of 500 jobs.
The
Harmony Gold Property encompasses a 440 square kilometer mineral claim holding
covering one of the world’s premier epithermal gold systems. The Project includes the Specogna Deposit
which is central to the property and contains a geological resource of over
three million ounces of gold.
Since
the discovery of the Specogna Deposit in 1970 over $40 million has been spent
by former operators. Their work
included trenching, drilling, underground bulk sampling, pilot mill testing,
environmental programs and feasibility studies. This work led to a proposal in 1987 by City Resources (Canada)
Limited to the British Columbia government to establish a 5, 800 tonnes per day
(2.1 million tonnes per year) processing facility involving pre-treatment of 31
million tonnes of open pit ore by nitric acid leaching (Arseno Process)
followed by cyanidation and production of gold bullion.
In
1988, although City Resources (Canada) Limited was in the final stages of
project certification, it decided not to continue with its proposal for
financial reasons. Permitting
proceedings were suspended.
In
1993, Misty Mountain Gold Limited initiated further planning of the Project
after examining the extensive Project data base and determining that excellent
potential for the development of an economically and environmentally sound gold
mine existed. In 1995, Romulus
Resources Ltd., an affiliate of British Columbia based Hunter Dickinson Inc.,
joint ventured the Harmony Gold Project, and then merged with Misty Mountain
Gold Limited. The merger brought
together a multi-disciplinary team of professionals with an excellent record of
environmentally responsible mine development.
In
1995, Misty commenced a comprehensive, staged program to explore and develop
the Project. This included a review of
voluminous historical, technical and environmental data, and the completion of
regionally extensive geochemical and airborne geophysical surveys. Late in 1995, a systematic diamond drilling
program of the Specogna Deposit commenced, utilizing large diameter core holes
spaced on a 20 metre by 290 metre grid pattern, oriented to the southeast and
drilled at an angle of minus 45 degrees.
In December 1996 this program was completed with a total of 34,627
metres drilled in 147 holes. The
extensive data base generated from this detailed drill program provides a solid
foundation for continuing mine development studies.
Current
and historical drilling of the Specogna Deposit now totals 79,766 metres in 538
holes with 41,27 gold assays completed.
The geological resources of the Specogna Deposit is 59 million tonnes
with an average grade of 1.66 grams gold per tonne. It is still open to the northwest and to depth with excellent
potential to develop additional reserves in these prime areas.
The
Specogna Deposit represents the mid to upper levels of an epithermal
hot-spring-type precious metals system.
Gold is distributed throughout a hydrothermal breccia unit that
parallels the northwest striking Speconga Fault for at least 700 metres and
also throughout stockwork quartz veining and pervasively silicified sediments
which extend laterally from the hydrothermal breccia for up to 210 metres. The Deposit dips moderately northeast for
over 300 metres and forms a mushroom-shaped cross section perpendicular to the
Specogna Fault. Approximately three
percent sulfides, mainly pyrite and marcasite, are found disseminated
throughout the Deposit. In addition to
the relatively evenly distributed gold, bonanza gold shoots occur scattered
throughout the Deposit. Examples of
these high grade shoots include drill intercepts of 42 metres averaging 41
grams gold per tonne and 46 metres averaging 40 grams gold per tonne.
Currently,
two exploration targets are being prepared for drill testing. The first target is potential bonanza gold
deposits which may have developed at depths of more than 200 metres below the
currently known Specogna Deposit. Plans
for exploration drilling into this deeper, throttled portion of the epithermal
system are being guided by careful structural analysis of the current data
base. The second exciting target,
located eight kilometers south of the Specogna Deposit, is contained in a
topographic high with a gold-in-soil anomaly and an airborne geophysical
response of the same magnitude and size as those of the Specogna Deposit. Coincidentally, commercial logging is now
underway in the area of this target and will facilitate exploration activities being
planned by Misty for the summer season in 1997.
REGIONAL
GEOLOGY AND MINERALIZATION![]()
The
major geological feature (Figure 4) within the region is the Sandspit Fault, a
dominant crustal structure that cuts diagonally across the Sandspit Gold
property at about 325°
Az and continues northwest and southeast for many miles. Parallel strands and subparallel splays are
apparent on air photos.
The
fault marks a distinct break in both physiography and bedrock lithology. Stream beds commonly dogleg when crossing
the fault line indicating the locus of most recent movement. To the west, the land rises up and forms low
hills and mountains; eastward the topography is flat and swampy.
According
to Sutherland-Brown “Rocks exposed in the west block are invariably older than
those exposed on the east-Yakoun Formation and Sandspit Plutons in the west,
Masset and Skonun Formations in the east.
The Sandspit Plutons are apparently aligned along the fault trace but
are cut by the faults and seem to have supplied detritus to the Skonun
Formation. The east block has dropped
many thousands of feet relative to the west; however latest movement appears to
have been east block up. This structure
was most likely active in the Cretaceous, and although some strands have not
been active since the Pleistocene, others most certainly have.”
Several
gold deposits and prospects in the region are mineralized along the Sandspit
Fault and splay structures occurring as veins, siliceous breccias, and silica
placement zones. The fault provided
permeability for the circulation of mineralizing fluids.
The
largest gold deposit in the region is the Harmony Deposit of Misty Mountain
Gold Ltd. containing over 3 million ounces of gold reserves located 40 km
northwest of the Sandspit Gold property.
Structure and lithologies are important ore controls. The Sandspit Fault is adjacent to the
deposit on the east side. A secondary
splay structure known as the Specogna Fault was a major control or channel for the
movement of mineralizing fluids. The
Specogna Fault runs immediately west of the deposit dipping 45-50oE. Mineralization occurs in quartz veins,
siliceous breccia and replacement zones within silicified conglomerate of the
Skonun Formation. Haida shales form the
footwall of the Specogna Fault and may have been a secondary control on the
localization of mineralization by creating an impermeable boundary on the west
side of the deposit. The gold is very
fine and occurs in association with widespread disseminated sulfides. Previously announced open pit ore reserves
are 7-9 million tons of 0.1 ounces per ton gold, contained within an area 300
by 700 metres (City Resources, News Release, June 19, 1987, Vancouver
Stockwatch). Recently Misty Mountain
announced that metallurgical tests yielded greater than 90 percent gold
recovery enabling the cut off grade to be lowered to 0.035 oz gold per ton and
thereby increasing the mining reserve to 28 million tons averaging 0.061 oz
gold per ton (Northern Miner, July 6, 1987).
Other lesser gold showings in somewhat similar geological environments
are known (Southeaster, STO, Bella and Marino).
Outcrop
on the Sandspit Gold property is sparse except along the Sandspit Fault
escarpment, along the coastline, and in local creeks. Rocks are Yakoun Formation tuffs and agglomerates of Jurassic age
and quartz diorite and diorite of Cretaceous age.
Yakoun
Formation volcanics are widespread and occur from the western boundary of the
claims to the scarp adjacent to the Sandspit Fault. Along the cliffs, hornfelsic and pyritized Yakoun agglomerates
are cut by a large number of subparallel subsidiary faults that mostly strike
330 to 320° Az west and dip 60 to 80 degrees
northeast (Sutherland-Brown, 1968)
Honna
Formation conglomerate of Cretaceous age occurs west of Copper Bay and the
property in fault contact with the Yakoun volcanics (Christie and Howell,
1984). Honna is more common in this
area than shown on Figure 7.
Quartz
diorite intrusions cut the Yakoun volcanics forming a narrow belt elongated
subparallel to the Sandspit Fault system.
Their emplacement was apparently controlled in part by the Sandspit
Fault and the intrusions were themselves faulted by later movement.
Rhyolite
dikes are known locally. An intensely
altered dike with up to 20 percent sulfide replacement mineralization occurs
west of Copper Bay (Christie and Richards, 1982).
Hydrothermal
alteration and sulfide mineralization are widespread. The area with the highest gold values at Baxter Creek corresponds
to an area of locally intense shearing and silicification with up to 5 percent
disseminated arsenopyrite in rhyolite tuffs.
The Baxter Creek mineralization is 100 metres west of the Sandspit Fault
system. On a local scale, other
secondary structures are mineralized, (figure 11). Work in 1997 showed saussuritized plagioclase phenocrysts in most
outcrops of the diorite intrusives (figure 11)
It
is envisioned that the gold zones were deposited from a shallow epithermal
system. The overall size of the systems
or deposits is potentially large (similar to Misty Mountain). Epithermal deposits typically display
variable grades and complex local configurations due to steep temperature and
pressure gradients in the near surface environment. They may form a series of sheeted veins and breccia zones rather
than a single discreet vein. Fault
structures and variation is permeability with the stratigraphy are major
controls for the localization of deposits.
Three
types of mineralization were found during reconnaissance work on the SNOW
Property; 1) clay sericite, disseminated pyrite and quartz-carbonate vein
mineralization; 2) very fine grained semi-massive to massive sulfide
mineralization in volcanic tuff and; 3) massive siliceous mineralization.
The
clay-sericite, disseminated pyrite and quartz-arsenopyrite vein mineralization
is found on the Baxter Creek Grid along the Sandspit Fault to the north and
south and as a float boulder in Copper Bay Creek (figure 2). It is more common in the diorite intrusive
rocks, but it is also found in the volcanics at Baxter Creek. this mineralization is controlled by the
Sandspit Fault trend and northwest trending orthogonal splays off of it. it is characterized by gold-arsenic
mineralization.
Semi-massive
sulfide mineralization, possibly syngenetic in origin, was found in the Yakoun
tuff sequences along Copper Bay Creek near the centre of the SNOW 6 Claim, on
the south fork of Baxter Creek at the southwest end of the Baxter Creek Grid
and in the H-Grid area near the north end of the SNOW 4 Claim (figure 2). No economic mineralization has been found in
the massive sulfides to date, but the zones discovered may represent barren
pyritic cores with good gold potential around them. The mineralization on the south fork of Baxter Creek was
discovered while prospecting upstream from a highly anomalous (12,000 ppb Au)
heavy mineral sediment sample.
Massive
siliceous (50% silica) mineralization with up to 5% disseminated pyrite was
found on the cliff face 500 metres northeast of DDH-85-1. This zone was found to contain only weak (to
25 ppb) gold mineralization. This zone
could represent a leached zone with better gold potential at depth. Samples, descriptions and assay results from
the mineralized areas can be found in the 1987 assessment work on the SNOW
Property (Fairbank, 1988).

Holes
85-1 and 85-3 are 175 metres (575 ft.) apart aligned along the projection of a
structure that appears to control alteration and mineralization at Hole
85-1. Drill hole intercepts are
correlated with trench assays in Figure 9 and indicate that the zone is steeply
dipping and persists to at least 25 metres (82 ft) in depth. The mineralized interval is 10 to 20 metres
true width. The mineralized zone is
open to the northeast/southwest along strike.
At hole 85-3, the mineralization is open to the northwest.

Chip
samples taken by B.C. Fairbank, P.Eng. of bedrock exposures in the trench at
85-1 assayed 0.088 oz/ton gold over 1.8m (6 ft) and 0.205 oz/ton gold over 0.8m
(2.6 ft.). Both samples are
perpendicular to the structure. They
are brecciated and silicified (vuggy) light gray, fine grained rhyolite(?) with
visible disseminated pyrite and arsenopyrite.
A composite chip sample of broken drill core between 19.75m and 22.3m in
Drill Hole 85-1 assayed 0.048 oz/ton gold.
These results are within the limits of variation expected when compared
with those reported by Lornex.
Drill
holes in the area of gold mineralization (85-1,2,3 and 4) intersected variably
altered Yakoun lapilli tuff and agglomerate (Figure 7). Drill Hole 85-5, 200 metres southwest of
85-4, intersected quartz diorite.
Structure
is an important ore control.
Mineralization in the drill holes is associated with a structure
striking 55o and dipping 80oN. Shearing, brecciation and silicification have occurred along this
particular structure. Other structural
orientations may also be important. For
example, the Sandspit Fault striking north-northwest is 100 metres northeast of
the known mineralization. A N-S fault
between holes 85-4 and 85-5 is interpreted from magnetic data. The north-south structural trend intersects
the mineralized 055o trend at a prominent magnetic low, the
significance of which is unknown.
A
total of 339 samples were split and analyzed with average sample length of 6.2
feet (1.9m) although samples in mineralized areas were shorter. Analysis was for fire assay-geochemical gold
with fire assay checks on all samples above 1.0 gram per tonne (1000 ppb) plus
I.C.P. for trace elements silver, copper, lead, zinc, arsenic and antimony.
DDH-88-9
DDH-88-9
was drilled to a depth of 348 feet to test the north end of an I.P./Resistivity
anomaly. It intersected weakly
silicified andesitic wacke or agglomerate with up to five percent stockwork
fracture and disseminated pyrite. The
pyrite and silicification explain the I.P. resistivity anomaly that was the
target of this hole. High values of 14
ppb gold and 31 ppb arsenic indicate that the Baxter Creek zone was not
intersected in this hole, however, the highest zinc (568 ppm) and copper (892
ppm) values in the 1988 drill program were intersected. The base metal mineralization is likely
pre-Sandspit Fault in origin and not a target for further work.
DDH-88-10
DDH-88-10
was drilled to test northern extension of Baxter Creek Zone mineralization
intersected in DDH-85-1. It intersected
andesitic wacke and agglomerate with scattered calcite and quartz veins, and
weak clay-carbonate alteration with locally up to 5 percent disseminated
pyrite. The highest gold (0.102 oz/t)
and silver (33.5 ppm) values returned from the 1988 drilling were intersected
from 36.29-37.33m (119 to 122.5 ft).
These high values were represented by 1.1 feet of medium grey brecciated
quartz stringers, in a broad clay-carbonate altered zone.
DDH-88-11
DDH-88-11
was drilled to cut at depth the gold intersects in DDH-85-3 and Trench 3. it was drilled through porpyllitically
altered, medium grained diorite cut by carbonate veins and containing local
andesite inclusions. Three zoned of
gold mineralization were intersected: 43.4-47.2m (142.5-155’) 0.047 oz Au/ton;
56.8-59m (186.5-193.5’) 0.043 oz Au/ton; and 78.3-80.3m (257-263.5’) 0.039 oz
Au/ton. These zoned were characterized
by up to 10 percent fine grained disseminated pyrite and arsenopyrite with
local grey quartz veins and shearing.
Good correlation can be seen between Trench 2 (1987), DDH-85-3 and
DDH-88-11 (figure 8).
DDH-88-12
DDH-88012
was drilled to test a southern extension of the Baxter Creek mineralization as
evidenced by arsenic soil geochemistry anomalies and gold-arsenic mineralized
zones in the west end of Trench 3 (1987).
It cut carbonate veined, propyllitically altered, medium grained diorite
with local andesite inclusions. three
zoned of gold mineralization were intersected: 12.4-24.2m (77-79.3’) 0.039 oz
Au/ton; 77.1-83.1m (253-272.6’) 0.031 oz Au/ton and 103.9-105.5m (341-346’)
0.045 oz Au/ton. The mineralized zones
were characterized by fine grained disseminated pyrite and arsenopyrite with
local grey quartz veins.
DDH-88-13
This
hole number was assigned to a hole not drilled. DDH-88-13 was proposed to test the southern extension of Baxter
Creek mineralization in the vicinity of Trench 4 (1987) but was not drilled
because of the poor results in DDH-88-14.
DDH-88-14
DDH-88-14
was drilled to test arsenic soil geochemistry anomalies and altered, weakly
mineralized zones in Trench 3. I cut
carbonate veined, propyllitically altered, medium grained diorite with local
andesite inclusions, but was only weakly mineralized with scattered quartz
veins and disseminated pyrite and very low (high 48 ppb Au) analysis results.
DDH-88-15
DDH-88-15
was drilled to test a coincident I.P./Resistivity high and arsenic soil
geochemistry anomaly. It cut minor
carbonate veins and propyllitically altered andesite wacke and agglomerate with
4-5 percent disseminated pyrite. The
hole returned very low gold values (6 ppb) but elevated copper to 247 ppm and
zinc to 96 ppm.
575
metres of trenches plus seven prospect pits totaling 48 metres in length were
constructed in the Baxter Grid area from October 2 - 5, 1987. Trenches were oriented along grid lines to
evaluate soil geochemistry and magnetic anomalies.
The
two lithologies intersected on the grid are medium grained quartz diorite to
diorite and andesitic agglomerate and lapilli tuff. The intrusive is mapped by Sutherland-Brown (1968) as being
Cretaceous to Tertiary in age. Its’
contact with Trenches 2 and 3 and in some of the drill holes. in general, the intrusive contact is mixed
zone which strikes 020°
through the centre of the grid with andesite in the east and diorite in the
west.
Superimposed
on these lithologies is a broad area of propyllitic alteration characterized by
5-25% chlorite, 0-5% epidote, 0-3% disseminated pyrite and 0-5% disseminated
magnetite. Narrow (10 cm) mineralized
zones consisting of quartz veins (5-10%), pyrite/arsenopyrite (0-10%), and
calcite (10-25%) occur in a wider 50m quartz (10-25%), clay (25%) pyrite (0-5%)
and calcite altered zone. Mineralized
zones and individual veins generally strike 020° on the east in the andesite and turn to 070° in the quartz diorite in the west.
Mineralization
type is dependent on host rock type with stronger silicification, brecciation
and gold mineralization where the host rocks are siliceous andesite tuff such
as near DDH-1 and with more clay-carbonate alteration in the quartz diorite
host near DDH-88-14 and further west.
A
Komatso PC400 LC-3 tracked excavator from O’Brien Fuerst Logging Ltd. was used
because of its ability to traverse swampy areas and to dig one metre wide pits
up to six metres deep. Trenches were
dug continuously into bedrock wherever possible. Local thickness of till to bedrock in several areas. In these cases, deep pits within the
trenches were dug in an attempt to cut bedrock. Six pits were dug in subsequently filled in for safety reasons in
the Trench 1 area. The remainder of the
trenches remain open, although a number are filled with water.
Trenches
were surveyed with compass and tape and geologically mapped at a scale of 1:100
and 1:500. Rock sampling generally as
five metre chip samples from the bottom of trenches, with shorter samples in
mineralized zones was done. A Wajax
pump was required to pump out the trenches for inspection. Samples of the backhoe dump material were
taken where access could not be had due to water or unstable banks.
Gold/arsenic
mineralization was intersected in Trenches 2, 3 and 4. Of these, the best mineralized zone was from
the southeastern end of Trench 2 which was 9.0 metres wide and averaged 854 ppb
gold (0.025 oz/t.). This zone was also
encountered in drill hole DDH 85-3 open to the west where water and mud covered bedrock. Similar weaker mineralized zones were intersected near the center
(100 ppb) and at the west-end (208 ppb) of Trench 3 and (47 ppb) in Trench 4
(Figure 6). All of the gold zones show
highly anomalous arsenic up to 800 ppm.
The zone at the west end of Trench 3 was sampled from backhoe dump
material and is open to the west.
Arsenic
has been shown to be associated with gold mineralization on the Sandspit Gold
property (Figure 9). Arsenic
concentrations of greater than 25 ppm in soil are considered to be
anomalous. Regional soil arsenic
anomalies indicate a large target area for potential mineralization measuring
500 by 500 metres (Christie and Richards, 1982). Arsenic values up to 79 ppm along with spotty gold values in soil
on the cat trail to the west of 85-1 indicate excellent potential for the
occurrence of gold veins or other forms of more extensive mineralization
between Anomaly A and the known gold zone in drill holes.
Soil
anomaly B corresponds to a magnetic high (Figure 8). The relationship of Anomaly B to known mineralization is
unclear. The highest values (2250 ppm
As, 80 ppb Au, and 198 ppm As, 5 ppb Au) are in an area of extensive overburden
cover. Regional soil results show
arsenic to be present in soils between Anomaly B and drill hole 85-1, however,
results cannot be plotted accurately relative to the detailed grid. Fill-in sampling will be required to enable
an accurate interpretation of the soil data.
Eighteen
soil samples were taken at the bedrock/soil (till) interface in Trenches 3 and
4 to evaluate the property soil sampling results and optimum depth of
sampling. Analytical results of the
“normal” auger sampling and deeper trench sampling compare well in arsenic, but
anomalous gold values found above bedrock in the trenches were missed in
shallower soil samples.

The
results show that lack of anomalous gold soil geochemistry on the grid is not
indicative of the potential for gold mineralization in bedrock. Arsenic appears to be a good tracer element
for masked gold zones.

Two
rock samples were taken during the 1988 drilling program. MAH 101 is a sample of quartz vein with
arsenopyrite similar to Baxter Creek mineralization. it was 40 cm float boulder found along Copper Bay Creek. MAH 102 was a sample of argillic altered
diorite from a 3 metre deep water sump dug at B.L. - =00S on the Baxter Creek
Grid. These samples returned the

Sample
MAH 101 is a significant discovery.
Values of 9200 ppb (0.268 oz/t) gold, 0.34% arsenic, 0.15% antimony and
5.9 ppm silver are similar to those from the Baxter Creek Zone, but this sample
was found 3 kilometres south of the Baxter zone. A concerted effort should be made to fine the source of this
boulder.
The
gold and arsenic values from sample MAH 102 confirm the presence of low-grade
Baxter Creek Zone type mineralization under thick till cover east of
mineralization previously intersected in Trench 4. Further trenching is recommended to determine the extent of and
grade of the mineralization.
Glacial
till comprising the entire depth of a soil pit at 2+50SW, 0+50NW is composed
primarily of diorite boulders which probably have not been transported very
far. Analytical results of a soil
profile taken of the pit wall are as follows:

These
results show that soil samples should be taken as near to bedrock as possible
and that arsenic is the best soil indicator for gold zones in the Baxter grid
area.
From
August 1 - 6, and September 12, 14, 1985 and arsenic/gold soil auger sampling
program was completed with 50 metre line spacing and 25 metre sampling over the
Baxter Grid. Additional lines of
samples were taken along main access road and the bank of Baxter Creek. A few scattered anomalous gold values
(>20 ppb) were obtained but arsenic values up to 2150 ppm showed a strong
trend along and to the northwest of the grid baseline (Figure 9). Weaker arsenic values in this trend between
line 1+00S and 0+00S are probably a result of thicker till in this area. This soil sampling program lead to follow-up
trenching and was successful in locating covered mineralized zones.
The
Lornex “H” grid area is at the intersection of the Sandspit Fault System with a
N-S break in the airborne magnetic data interpreted to be a major cross
fault. The area of intersection of the
two faults is a good geological environment for the formation of epithermal
deposits.
An
arsenic soil anomaly was reported on the west side of the H grid area by
Marjorem (Christie and Richards, 1982), however, Lornex’s soil results were
consistently low in gold and other pathfinder elements including arsenic
(Serak, 1985). The disparity may be due
to different sampling techniques.
Marjorem obtained deeper samples using an auger.
Along
the base of the scarp slope reflecting the Sandspit Fault, intensely fractured
and clay altered volcanics with 5 percent disseminated pyrite and arsenopyrite
occur in a road out outcrop. Samples by
the author at two locations 200 metres apart returned negative gold, arsenic
and antimony assays.
Exploration
in the H grid area has not shown direct evidence of gold mineralization,
however, it has shown that hydrothermal alteration associated with the Sandspit
Fault system is of regional extent.
Induced
polarization, resistivity, and magnetic surveys were conducted at 100 metre
line spacing on lines numbered by hundreds over the Baxter Grid Area. Bulk mineable epithermal gold deposits would
be expected to produce an IP anomaly (Percent Frequency Effect) due to
disseminated sulfides and a resistivity high due to pervasive
silicification. Primary targets would
be overlapping or coincident IP/resistivity anomalies that extend to depth.
Two
Phoenix Model IPV-1 Induced Polarization and Resistivity receiver units were
used, together with a Phoenix Model IPT-1 IP and Resistivity transmitter
powered by a 1 kW motor-generator. IP
effects were recorded as Percent Frequency Effects (P.F.E.) at operating
frequencies of 4.0 Hz and 0.25 Hz, while apparent resistivity values were
normalized in units of ohm-meters.
Dipole-dipole array was utilized to make all of the measurements using
interelectrode distances of 25 metres.
Four dipole separations were recorded in every case.
“Since
the Induced Polarization measurement is essentially an averaging process, as
are all the potential methods, it is frequently difficult to exactly pinpoint
the source of an anomaly. Certainly, no
anomaly can be located with more accuracy than the electrode interval length;
i.e., when using a 25 metre electrode interval, the position of a narrow
sulfide body can only be determined to lie between two stations 25 metres
apart. In order to locate sources at
some depth, larger electrode intervals must be used, with a corresponding
increase in the uncertainties of location.
Therefore, while the centre of the indicated anomaly probably
corresponds fairly well with the source, the length of the indicated anomaly
along the line should not be taken to represent the exact edges of the
anomalous material.” (Cartwright, P.,
Pacific Geophysical Ltd., 1987)
Results
are shown graphically in selected psuedosections in Figures 12, 13, 14 and 15.
In
general the Baxter gold mineralization shows up as a discontinuous IP effect
anomaly. Results appear to extend known
mineralization north and west of gold intercepted in drill holes DDH 85-1 and
DDH 85-3 respectively and also are corroborating evidence for potential
parallel mineralized zones to the northwest along the Baxter Trend. A distinct linear magnetic low, broadly
coincident with Baxter Trend mineralization may be due to removal of magnetite
by circulating hydrothermal solutions along a fault structure.
Two
electrical anomalies outside of the Baxter Trend area are apparent from the
survey.
A
large area underlain by resistive rock with an overlapping PFE anomaly
indicating disseminated sulfides occurs
in an area of no outcrop in the southeast quadrant of the grid. Trench 3 exposes volcanic stratigraphy with
no gold values of interest. A
gold-arsenic soil anomaly was detected in an earlier soil sample program on
line 3+00S between 0+25E and 1+50E within this zone.
To
the north along the access road, a strong PFE anomaly crosses Lines 0+00N and
1+00N centered at 1+00E. The anomaly
occurs across a narrow width of 100 metres and increases in intensity with
depth.
CONCLUSIONS
AND RECOMMENDATIONS
Gold
mineralization at Baxter Creek, assaying up to 0.096 oz/ton over 9.31 metres,
occurs in an environment suitable for the formation of large-scale bulk
mineable gold deposits. A gold zone 300
metres long, 10 - 20 metres wide and at least 25 metres deep is intercepted in
four drill holes and several surface trenches.
Good exploration potential exists to develop reserves along strike and
to depth in the known structure. Other
areas with anomalous geochemistry within the target area also should be tested
by drilling.
It
is anticipated that potential ore zones would be picked up within an
IP/resistivity survey. Disseminated
sulfide mineralization would give a good chargeability anomaly and pervasive
silica alteration would yield a resistive signature relative to unaltered
rock. The IP survey should be expanded
to guide a follow-up drilling and trenching program necessary to explore and
develop the property further.
The following program is recommended
for the Baxter Creek Target Area, Figure 16:
1.
Geological
mapping: creeks, other outcrops and
trenches with a view to interpreting
structural controls of mineralization.
2.
Backhoe
trenching: trenches will be access
routes for subsequent drilling.
In
the H-Grid area soil sampling with an auger should be done to detail the
arsenic anomaly and analyze for gold.
The grid should be extended to the west to ensure that the Marjorem
arsenic anomaly is covered completely.
Geological mapping is recommended to confirm and locate the interpreted
north-south fault and the Sandspit Fault zone should be thoroughly prospected.
Drilling
indicated widespread gold in the Baxter Creek Grid area, however, gold grades
intersected to date are too low to be of economic interest.
There
are a number of altered and mineralized areas on the Snow Property that have
only had scattered exploration efforts while work has emphasized the Baxter
Creek Zone mineralization. It is
recommended that a concentrated rock sampling program be undertaken to determine if there is significant precious metal
values in these areas. Continuous
sampling of altered or mineralized outcrops, plus sampling of mineralized
boulders on the beach and in streams is required.
Other
specific targets for further work can be seen of figure 4. These include the Copper Bay Creek boulder
(MAH 101) and sulfide showing (A), the south fork of Baxter Creek sulfide
showing (B), the H grid sulfide showing (C) and the Cliff showings (D) plus the
Mickle Barite showing (1500 metres northwest of C) and sulfide bearing boulders
on the beach from Copper Bay north. The
program objective would be to determine the presence of economic grades of
mineralization elsewhere on the property and would require further target
definition work.
