Greenland poised for new mine startups
The new cable car ready for shipping to Maarmorilik.
Two exploration projects have in a short time reached
levels of feasibility and the starting up of mining activity
has been mentioned more and more often. The 'ready to
go' signal before application of an exploitation licence is
getting closer, judged by press statements from licensees
at the former lead-zinc Black Angel Mine ('Angus & Ross')
in West Greenland, and at the giant molybdenum deposit('InterMoly') in East Greenland.
Angus & Ross plc
has in a press release dated 17 October
2007 provided the latest drilling update from one of
the new discoveries near the old mine, the Glacier discovery,
demonstrating the best grade so far with more high
grade zinc/lead intersections including 2.13 metres @
20.1% zinc and 10.2% lead. The Glacier zone is the third
largest body of mineralisation ever found at the Black
Angel property, after the Angel and Cover zones. It is now
known to extend 650 metres along its east-west strike,
and this year's drilling has extended the zone of mineralisation
roughly 150 metres to the west where it remains
open.
The thirty one holes completed this year, comprising 7353
metres of diamond drilling, should increase resources considerably.
The Company's consultants Wardell Armstrong
International are presently preparing an up to date Resource
Statement for the Glacier zone as well as a Bankable Feasibility Study pertaining to early pillar extraction from the old Black Angel mine itself.
As picked from a comment (20 September 2007) by
Robin Andrews, Chairman of Angus & Ross, "good progress
is being made towards the objective of re-opening
the mine and achieving production of ore in 2008." The
chairman continues (17 October 2007): "In addition, considerable
progress has been made in the interpretation of
the structural geology of the region so that planning is
already underway for a much enhanced exploration programme
in 2008. In the meantime work continues towards
the installation of a cable car which will enable
exploration drilling to be undertaken within the mine and
also will provide access for the production of high grade
ore from the existing pillars." It will be fascinating again to
see cable cars at Maarmorilik.
International Molybdenum Plc ('InterMoly')
, has
commenced feasibility level studies required to make a
development decision on the Malmbjerg project in Greenland.
This is stated in a press release of 10 June 2007 by
Quadra Mining Ltd. of which InterMoly is a subsidiary (82
%). The budget through to the end of the study period is
US$15 million with a completion target for the first half of
2008.

Work includes in-fill and geotechnical drilling, pilot plant
testing of a bulk sample, environmental permitting applications,
basic engineering and cost studies. Previous exploration
identified a NI 43-101 compliant Measured and
Indicated resource of 560 million pounds of contained
molybdenum and the current in-fill programme is designed
to add drill density and convert some material previously
categorized as waste to ore.
Paul Blythe, President & CEO comments, "The immediate
objective going forward is to confirm the economics of
the project, explore funding opportunities and to establish
a development strategy. An updated NI 43-101 compliant
Technical Report will follow this exercise and will allow us
to firm up design criteria and optimise development and
execution concepts."
The Malmbjerg project is located on the east coast of
Greenland and is one of the highest grade molybdenum
projects in the World amenable to open pit mining that is
currently being considered for development. The studies
carried out by 'InterMoly' before the acquisition proposed
a conventional open pit operation with a production rate
of approximately 23 million pounds per year of molybdenum
commencing in 2011.
The target at Malmbjerg is a porphyry Mo deposit similar
in style and morphology to the Climax deposit, Colorado.
Deposits of this type are typically large, measuring in the
hundreds of millions of tonnes with MoS2 contents typically measuring less than a percent of the rock by weight.
Late hydrothermal processes related to the intrusions
were responsible for alteration and deposition of molybdenum
sulphide mineralization. The mineralization occurs
as a diffuse zone of molybdenite with accessory tungsten
in fractures and stockworks in both the intrusives and
overlying sandstones.
Nalunaq Gold Mine takes over full interest of the property
Crew Gold Corporation ('Crew')
announced 1 November
2007 that Crew acquires 100% of Nalunaq Gold
Mine after an agreement to purchase the NunaMinerals
A/S 17.5% interest in the Nalunaq Gold Mine. Consideration
includes approximately CAD $2.5 million for the
shares plus repayment of all loans between NunaMinerals
A/S and Nalunaq Gold Mine of approximately CAD $2.2
million. In addition, NunaMinerals A/S will be entitled to a
1.5% NSR royalty on production in excess of 992,000
ounces cumulatively.

On completion, Crew will hold 100% of the equity in the
Nalunaq Gold Mine. The mine has been operational since
February 2004 and has produced approximately 195,000
ounces of gold at an average head grade of 16.3g/t gold. In
October 2006, Crew purchased the Nugget Pond processing
facility in Newfoundland, Canada, to process ore
from Nalunaq. Current production from Nalunaq is
80,000 to 90,000 ounces. Jan Vestrum, Crew President and
CEO commented, "I am pleased to announce the successful
conclusion of negotiations with NunaMinerals A/S. This
transaction enables Nalunaq and Nugget Pond to be operated
with maximum synergies and provides longer term
benefits to Nalunaq and Greenland. With a strong present
gold price and positive outlook for gold we believe this is
an excellent transaction for Crew Gold."
The Nalunaq resource is a narrow vein deposit consisting
of several high-grade "bands" typically carrying grades of
gold approximately 30 g/t or higher. Between the highgrade
bands, grades can vary between 10 g/t and 20 g/t. In
practice this means that the grades achieved on an ongoing
basis can vary considerably, but remain comparatively
high.
Nalunaq mine performance has continued to improve
with the average daily production for the month of
September reaching 510 tpd. This exceeds, for the first
time, the target of 500 tpd for an entire month. Year to
date 101,182 tonnes of ore was mined, an average of
approximately 370 tpd.
Shipping of ore to Nugget Pond continued as planned and
three shipments totalling 43,317 tonnes of ore were completed
to South Brook in Newfoundland, for subsequent
road haulage to Nugget Pond. Total ore shipments for the nine months to September 30, 2007 to Nugget Pond were
116,108 tonnes. At 30 September 2007, 12,582 tonnes of
run-of-mine ore was stockpiled at Nalunaq's port in
Greenland containing approximately 4,800 oz of gold. In
addition, there were 20,758 tonnes of ore containing
approximately 8,500 oz of gold at Nugget Pond. Gold sold
by Nalunaq during the nine months ending 30 September
2007 were 43,338 oz.
Successful certification audit of the mine operations at Seqi
A
Minelco A/S
press release of 1 November 2007 regarding
the company's Seqi olivine mine reports that a
certification audit of the quality and environmental control
systems at Seqi A/S in Greenland was carried out successfully
by SP Certification. The audit which involved the
laboratory, harbour, subcontractors, quarry and management,
was very successful. No deviations were noted, only
four suggestions for improvement were made by the auditor,
who was very pleased with the accomplishment and
results. SP's recommendation is that Minelco A/S shall be
awarded a certificate in accordance with ISO 9001:2000
as well as ISO 14001:2002.
The Seqi olivine mine, situated 90 km from Nuuk, is based
on a very large homogenous deposit of high quality
olivine, with reserves at least 100 million tonnes of olivine
ore. It is operated by Minelco A/S after the opening in
2005. The company supplies minerals and mineral products
to the steel industry. Olivine is used extensively as a
refractory raw material, as a slag conditioner in blast furnaces
and as a tap hole filler in electric arc furnaces.
Hudson Resources established DMS plant at the Garnet lake site
Hudson Resources Inc. has recently (12 October 2007)
published a number of highlights from the 2007 field campaign
in relation to their diamond prospect at Garnet
Lake in West Greenland. Highlights resulting from efforts
to follow up on the sensational find of a 2.4 ct. diamond
from the site, also reported in Minex 30 (February 2007).
The DMS plant at Garnet lake installed (Photo:Hudson).
-
On-site dense media separation (DMS) plant has commenced
operation.
-
A large tonnage of kimberlite has been extracted and
stockpiled for processing.
-
Drilling continues to confirm continuity of the Garnet
Lake dike.
During the summer, Hudson mobilized overland to the
site at Garnet Lake two 25 tonne excavators, a Tamrock
air drill and a seven tonne primary jaw crusher. Hudson is
now well set up to expand the pit area in 2008 and extract
additional tonnage from other locations along the
Garnet Lake dike as identified by the recent drill program.
"Construction of the new "Dense Media Separation" diamond
recovery plant has been completed and kimberlite
is currently being processed from a stockpile of 300 to
500 tonnes that has been mined and placed adjacent to
the plant. The plant has a three-stage crushing circuit with
a five-tonne per hour operating capacity. Initial results
indicate that a 3% heavy mineral concentrate is achievable.
The plant is currently processing around 2.5 tonnes/hr,
while generating a 6% concentrate in this early start-up
phase. Importantly, having the operating plant and all heavy
equipment on site will allow us to hit the ground running
in the spring of 2008, when we expect to take a much
larger bulk sample as we continue to evaluate the economics
of the Garnet Lake dike and surrounding targets."
James Tuer, Hudson President, continues: "The plant is
being operated by DRA Americas Inc. which also designed
and supplied the plant. Mineral concentrate produced in
the plant is being placed in locked containers and will be
shipped to Canada in November for final processing and
diamond picking. Several hundred tonnes of kimberlite has
been extracted from the dike and has been stockpiled
outside of the plant for processing. The total amount of
material to be processed in 2007 will be determined in
the next few weeks prior to the full onset of winter".
Crew Minerals diamond potential in the Maniitsoq area confirmed
Crew Minerals ASA released 3 October 2007 an update
for its 2007 diamond exploration activities in West Greenland.
The exploration has the following highlights:
-
Numerous new kimberlite dyke locations were identified
in the Maniitsoq region, and 73 samples totalling
approximately 2.3 tonnes were sampled for analysis of
diamond content
-
It was discovered that the known scattered occurences
of kimberlite dykes in the Maniitsoq region-seemingly
belong to three distinct dyke swarms
-
Each dyke swarm hosts several segments with 2-2.5 m
width over several hundred metres of strike length
-
The largest dyke swarm is nearly 30 km long
A typical kimberlite outcrop in the Maniitsoq area (Photo:GEUS).
During 2006 and 2007 Crew Minerals was granted three
exclusive exploration licenses with a total area of 2,264
km2 within the two main kimberlite provinces of West
Greenland.
Expectations were raised after a reconnaissance campaign
in 2006 showed that 18 out of 20 samples from widely
scattered kimberlite dykes throughout the Maniitsoq licence
areas contained diamonds (Minex 30). Also, several
new kimberlite occurrences were discovered as the result
of systematically traversing areas in the 'up-ice' direction
of previously reported kimberlite indicator minerals(KIMs) from till samples, suggesting a close spatial relationship
between KIMs in overburden and their kimberlite
sources throughout the Maniitsoq province.
The 2007 campaign showed that the known Majuagaa-Sillissannguit trend within the northern part of the region
constitutes a single, nearly 30 km long dyke swarm,
possibly one of the largest kimberlite dyke swarms known
in the industry. 1.4 tonnes of kimberlite samples from 45
sites were collected for diamond test work, and a further
0.9 tonnes were collected from 28 other sites in the
Maniitsoq region. With the discovery of the many new
occurrences there now appear to be three main linear
kimberlite trends in the Maniitsoq region, each with two
or several parallel dykes arranged in an en echelon pattern.
These highly encouraging discoveries suggest that the
Maniitsoq kimberlite province is controlled by very large,
deep-seated crustal structures.
In addition, new sampling totalling approximately 1 tonne
of till materials (glacially transported overburden) for kimberlite
indicator minerals was also conducted in a previously
little explored part of the Sarfartoq kimberlite province.
All kimberlite and till samples will be processed for
diamond content and KIMs by renowned Canadian laboratories,
and results are expected by the end of 2007.
Greenland Diamonds Ltd. - a new player in Greenland diamond exploration
The diamond exploration interest in Greenland is continuing
to expand and is now moving to the South. Newly
established Australian Redox Diamonds Ltd. has entered
into an option agreement to access data and information
for a diamond exploration play in southern Greenland.
The company has at previous sampling located kimber litic
indicator minerals indicating that they are derived from
diamond stability depth. The samples were collected from
streams draining a number of circular lakes and Redox, via
a fully owned subsidiary, Greenland Diamonds Ltd, has
been granted two exploration licenses covering approximately
500 km2. Diamond stability field chrome diopside
and pyrope grains were recovered from these samples
and only minor follow-up has been undertaken to date.
Redox carried-out confirmatory and additional sampling
in the region during August 2007.
NunaMinerals collected 4000 mineral exploration samples
A map of the Qussuk - Storø area showing the distribution of gold (Map:GEUS).
NunaMinerals A/S announced 30 October 2007 that the
company has shown an increase of 18% compared to the
2006 field work by collecting 4000 mineral samples from
eight of the project areas. Many of the samples are drill
core or channel samples and thus of high quality. Grass
root exploration and prospecting have been carried out in
most of the NunaMinerals licence properties, which cover
7900 m2.
One of the important work areas is the Storø Gold project,
which is situated approximately 40 km north-east of
Nuuk. From this project 1816 metres of diamond drilling
was completed in 12 holes and visible gold was encountered
in six of the holes. The drilling was aimed at demonstrating
continuity of the so-called BD zone and includes
drilling at high elevation close to the BD zone surface exposure.
Furthermore, infill drilling was completed in the
Main Zone area. A total of 829 rock samples have been
collected for analysis. Best gold values based on standard
30 g fire assays reveals 15 g/t gold over 2 metres and 4
g/t over 5 metres.
Different assay techniques have demonstrated a pronounced
nugget effect within the gold mineralised system.
In order to quantify the nugget effect, seven micro bulk
samples totalling 1200 kg have been collected. These samples
have been shipped to the SGS-Lakefield laboratory in
Canada, for test processing and the total gold content will
be analysed.
It is still NunaMinerals' strategy to seek an international
partner for the Storø Gold Project; a partner who can
contribute with additional technical and financial capabilities.
At the Qussuk project, which is situated approximately
60km north-east of Nuuk, the company has systematically
collected channel samples over some of the mineralised
areas identified in previous years. In other prospective
areas sediment samples have been collected. A total of
544 rock samples of which 463 are channel samples along
with 238 sediment samples have been collected. Best gold
values based on fire assays reveals 7.5 g/t gold.
The Qussuk and the Storø areas have for many years also
been a target area for GEUS's scientific research. A recent
account in the GEUS Bulletin series deals with the discussion
of the relation of the gold mineralisations to the
Archaean geological history in the region. A map from this
account summarises the distribution of gold in the area.

True North Gems Inc. announced 18 October 2007 that
it has completed an additional 21 drill holes at its Aappaluttoq
ruby occurrence, and has intersected visible ruby
and pink sapphire mineralization in a total of 18 out of 46
holes. This additional drilling has extended the strike
length of the Aappaluttoq occurrence to 105 metres, at
the Company's 110 km2 Fiskenæsset Ruby Project.

made of Greenland rubies and sapphires (Photo: True North).
The distinct alteration zone that contains significant concentrations
of ruby and pink sapphire ("Host Zone") was
identified in all 46 holes on the Aappaluttoq occurrence.
Multiple intervals with visible ruby and pink sapphire have
now been documented in eleven of the 18 drill holes that
contain the mineralisation.
6 November 2007 the company released information on
the opening of an office in Bangkok, Thailand. The new
office facility will be used to sort and grade rough gems
from the Fiskenæsset Ruby Project. The new office facility
is located in one of the major centres for the international
coloured gemstone industry, and will be able to utilize the
highly specialised and experienced skill set available in
Bangkok.
The local polishing factories in Bangkok have extensive
experience with the sorting, grading, evaluation and polishing
of ruby and sapphire. The office will be located within
a well established and secure facility that will also allow
for the implementation of professional control and security
protocols during the sorting, grading, and processing of
True North's bulk samples. "With its proximity to the
established markets of Europe and the Arab countries, and
the new growth areas of China and India, Bangkok is the
international market place for purchasers of rough as well
as polished gems" noted Nick Houghton, True North
Director.
Ruby and pink sapphires are well known gemstones for
use in jewellery. As a marketing effort True North Gems
recently displayed new ideas for uses with Greenland ruby
and pink sapphire in jewellery.
Ironbark Gold identify new zones of high grade zinc in Citronen Fjord
3D view of the Citronen Fjord area (Map: Ironbark Gold)
The new player in Greenland base metals from 2007
Ironbark Gold Ltd. reported 12 October 2007 from
the company's Citronen Fjord property that new zones of
high grade zinc mineralisation have been identified:
-
Beach Zone: 6m at 7.8% zinc (Zn) and 0.8% lead (Pb)
from 108m, including 3m at 12.6% zinc, 1.3% lead (in
addition to the historic result of 6.3m at 6.5% zinc,
0.5% lead from 85.15m)
-
Discovery Zone: 5m at 7.2% zinc from 82m, including
2m at 12.1% zinc (in addition to the historic result of
16.6m at 10.6% zinc from 18.2m)
The Citronen Zinc Project was discovered in 1993 by
Platinova A/S and was the subject of campaigns of investigation
until 1998 and at a time of exceptionally low base
metal prices (Zinc ~US$0.40/lb). Comparatively zinc
prices since mid 2006 peaked at
US$ 2.00/lb and with a 2007 level
somehow stabilising around ~US$
1.50/lb. A target of at least 20 Mt to
25 Mt was estimated by Platinova
A/S based on surface mapping and
gravity data to date within the main
project area. Ironbark considers in its
first year of operation that Citronen
Fjord offers; Large scale + Long life +
Low cost + Low risk + Exceptional
exploration potential.
The company reported 22 November 2007
also that the general resource base for the
Citronen Fjord property now is calculated to 72.5
Mt @ 4.2% Zn, 0.5% Pb (3% Zn cutoff).
Ironbark has secured more than 1,700 km2 of exploration
ground surrounding Citronen, offering unfettered access
to further exploration success. Ironbark owns several
other prospective base metal and gold projects in North
and North-East Greenland, which it plans to pursue progressively.
Annual Report 2006 released
The Greenland Bureau of Minerals and Petroleum's annual
report 2006 was released during the summer as a 16
pages booklet with informative and fact filled overview of
the year's achievements.
As is customary the opening address by the minister in charge of the mineral resources sums up the importance of
increasing the mineral exploration
and the exploitation. At the end of
2006, a total of 40 exploration
licences, 14 prospecting licences,
and two exploitation licences for
hard minerals had been granted.
This is the highest level of activities
since 1997. The exploration
has been particularly directed
towards gold, molybdenum, zinc,
nickel, rubies, zirconium and diamonds.
The high level of activity
has increased even further in the
first months of 2007.
