Nalunaq Gold Mine continues production
On 2 July 2009 Angus & Ross plc was pleased to announce that it has unconditionally acquired all the assets,
infrastructure, inventories and goodwill at the Nalunaq
gold mine in Greenland from Nalunaq Gold Mine A/S, a
subsidiary of Crew Gold Corporation for a total consideration
of $1 million.The company intends to bring the
Nalunaq mine quickly back into production, and it hopes
the mine will produce cash flows very soon.The deal
reflects a revision to that announced on 7 April 2009
which originally envisaged the purchase of shares of
Nalunaq Gold Mine.
View westwards along the Nalunaq Gold Mine valley.The mine town and harbour road are situated in the valley floor. Mine roads on the mountain slope are connecting the three underground working levels (right).
Nicholas Hall, Chief Executive Officer, commented: "The
completion of the acquisition of the Nalunaq mine is a major
step in the transformation of the company.We believe the
Nalunaq mine can be operated profitably by adopting a mining
method that will enable us to employ local labour and by producing
concentrate on site.We look forward to progressing with
New mineral showings in southern West Greenland found during GEUS field work
Significant PGE discoveries in the Precambrian
Fiskenæsset anorthosite complex
The Fiskenæsset anorthosite complex in southernWest
Greenland has a present strike length of more than 200
km. It is composed of anorthosite, gabbro-anorthosite,
gabbro, chromitite and a variety of ultrabasic rocks. It has
been repeatedly deformed and metamorphosed.
Map showing part of the Fiskenæsset Anorthosite complex (blue, grey and purple). Black stars show the positions of the chip/channel profiles with the highest PGE values. Insert the operation during saw cutting for channel profile sampling.
Recent field work comprising detailed mapping, chip and
channel sampling of a more than 5 km long, and several
tens of metres thick, layer of ultrabasic rocks comprising
peridotites, bronzitites, pyroxenites and hornblendites has
revealed significant PGE concentrations.
Several chip and channel profiles have been sampled
across the ultramafic layers.The peak value is 1.9 ppm Pt + Pd over 1 metre (marked with black stars on map). In
the same profile, values of 614 ppb Pt + Pd over 5 metres
have been found. Furthermore, 5 km along the strike
towards the east, a profile with grab samples yielded a
peak value of 1.1 ppm Pt + Pd and 27 ppb Rh. Chip and
channel profiles on other sites in the same suite of ultramafics
have also yielded elevated PGE contents.
Mineralogical investigations of heavy minerals in the PGE
reef proved that the PGE occurs as discrete minerals such
as: Froodite PdBi2; Sobolovskite (Pd,Pt)Bi; Insizwaite
Pt,Bi2; Maslowite PtTeBi; Michenerite (Pd,Pt)TeBi and
The area investigated is situated next to the sea with
excellent access for larger vessels.The discovery of these
PGE occurrences indicates that further PGE mineralisations
may be present in the large Fiskenæsset complex.

6 g/t gold-containing quartz veins discovered
Sheared rusty amphibolite outcrop containing
569 ppb Au gold in the Bjørnesund
area.The structure can be followed for
several hundred meters along the strike.
During the GEUS field season in 2009, a research team
visited the area north of the Sermilik Fjord in order to
study the potential for hydrothermal gold mineralisation.A
narrow quartz vein system was studied at 51°0.1'W and
63°31.9'N.The veins are 10–20 cm wide and locally, several
parallel veins form a laminated texture.An in situ rock
sample yielded 6370 ppb Au whereas another vein recorded
only 5 ppb Au. Gold is associated with iron oxides and
hydroxides, suggesting remobilisation during weathering of
primary sulphides.Although only one of the veins shows
high gold values, the area is regarded as promising for further
Furher information: Jochen Kolb (email@example.com).
Stockwork silver-copper mineralisation realised
A showing that can be followed over several km south of
Ameralik Fjord was revisited after the discovery of elevated
gold and copper reported in 2005 from a float sample(50°81.4'W and 64°04.0'N). Stockwork-type, mm-scale
quartz veinlets cross cut the Archaean gneiss at the site.
Geochemical analysis (n = 13) yields high metal contents
of 0.1–2 wt.% Cu and 1–25 ppm Ag, with enriched values
for Au, Mo, Zn and Bi.The veins show moderate to steep
dips and NW–SE major strike direction.The hydrothermally
mineralised stockwork zone is situated between
two regional N–S trending, Proterozoic faults that display
a right lateral step.The structural position of the stockwork
zone represents a dilational jog linking the two
faults. Focusing of fluids, and stockwork-type veining and
mineralisation, are controlled by regional anisotropies represented
by the dilational jog. Furher information: Jochen
New anomalous gold values located in the
Prior to field work, the greenstone belt occurring in the
Bjørnesund area, southernWest Greenland, had shown
promise of hosting gold.The purpose of the field work
was to verify this potential and to follow up on alteration
anomalies derived from Aster remote sensing data.A several
tens-of-metres-wide shear zone was studied at
50°16.2'W and 62°54.4'N at 555 m elevation above sea
level in the BjørnesundWest area.The zone can be followed
over several hundreds of metres along the strike. In
detail, this shear zone contains a 50 cm yellow-brownish, rusty stained amphibolite, which hosts
parallel quartz-carbontate veinlets.
Chip samples over 50 cm yielded 569
ppb Au, whereas a similar amphibolite
1.5 km towards the southwest yielded
31 ppb over about 10 m.
This new occurrence at Bjørnesund
West can be put into the regional
context because several rocks with
elevated gold content of several hundred
ppb have been reported from
earlier work by NunaOil A/S in the
1990s in the region east of
Bjørnesund.These zones with elevated
gold content are located in a
thrust-shear zone located between
meta-quartz-diorite and gneiss and
this structure can be followed for at
least 10 km along the strike.The new
gold occurrence from BjørnesundWest represents the
western continuation of the same thrust-shear zone and
consequently adds to the overall potential of the
Bjørnesund greenstone belt, which could host zones with
higher gold contents than recognised so far. Furher information:

Hudson drill results confirm high
grade REE zones on the Sarfartoq
Hudson Resources Inc. is pleased to report 4 November
2009 that drill results from the company's 2009 exploration
programme at the Sarfartoq Rare Earth Element(REE) Project in western Greenland confirm the potential
of a major new REE discovery.
Shearzone from the fenitised alteration rim of the Sarfartoq
Carbonatite complex – a part of the REE Project in the area.
Nine drill holes totalling 1,331 metres of reconnaissance
drilling were completed in three target areas on the company's
100% owned Sarfartoq license.Three holes (355 m)
were completed on the ST40 target, four holes (573 m)
on the ST1 target and two holes (402 m) on the ST19 target.
All three target areas underwent surface exploration
earlier in the year and yielded significant REE results.
Highlights are as follows:
0.25m of 2.19% TREO including 9.55m of 3.98% TREO in Hole SAR09-04
29.90m of 1.38% TREO including 12.45m of 2.18% TREO in Hole SAR09-05
63.10m of 1.02% TREO including 11.95m of 1.50% TREO in HoleSAR09-06
Neodymium oxide and praseodymium oxide average over 25% of the TREO
10.22m of 1.36% TREO in Hole SAR09-03.
Neodymium oxide and praseodymium oxide average over 54% of the TREO
Europium oxide averages 1.3% of the TREO
16.00m of 1.02%TREO with several smaller intersections of more than 1% TREO
All elements reported by ALS Chemex in parts per million (ppm).Total Rare Earth Oxides (TREO) are
converted using atomic weights based on the formula REE2O3. 2. Neodymium and praseodymium and
europium oxide expressed as a percentage of total rare earth oxides.
These initial drill results confirm that the Sarfartoq Project has
the potential to host several rare earth deposits stated James
Tuer, Hudson's President. "We are very pleased with the grade
and thickness of the intercepts, particularly at ST1, which suggests
the potential for a high-grade, large tonnage, near surface
body.The results of ST40 also confirm the high proportion of
neodymium encountered on surface.The fact that these two
zones may be joined over a distance of 2.5 km is extremely
encouraging.While the two holes (8 and 9) drilled into ST19
did not reach the targeted high-grade zone consistent with
some of our highest REE surface sample assays, strong mineralization
of 1.0%TREO over 16m demonstrates the presence
of widely spread mineralization in the project area.We are
planning to move ahead aggressively in 2010 with an expanded
drill program, geophysical surveying and metallurgical test
work to allow us to rapidly advance this exciting project.
Skaergaard Gold-PGM project
moves to next stage following positive
scoping study review
Platina Resources Limited has released plans for its 2010
activities at Skaergaard project on Greenland's East coast.
The Company is embarking on a +6,000m diamond
drilling programme aiming to delineate an area of higher
gold grade within the intrusion.The drilling will be in a
grid of 500m spacing, with an additional 2 or 3 exploratory
holes aimed at increasing the size of the known
resource. We will also be collecting a bulk sample for
additional metallurgical test work said Mr.Thomas
Abraham-James, Exploration Manager, 7 October 2009
and added the following key points from the Skaergaard
Gold zone map of the Skaergaard intrusion. Insert is
the legend to the map. After:
Platina Resources Ltd.
Commenting on the announcement, Platina's Managing
Director, Mr Rob Mosig, said: "We are very pleased with
the outcomes of this interim Scoping Study Review, which
has further increased our confidence in the quality of the
Skaergaard Project and its potential to deliver an outstanding
international production opportunity for the
Conceptual underground mine development of 2.4 Mt
pa with operating costs ranging from US$49-81/t.
Excellent bench-scale metallurgical recoveries of gold,
palladium and platinum achieved from bulk samples –
up to 92.7% gold recovery via flotation.
Compelling evidence suggesting a potentially highergrade
gold zone (>
4g/t Au +PGM)
Pre-Feasibility Study to continue with targeted
completion by December 2011.
Nearby to Skaergaard the Company will be conducting
follow-up exploration activities at the Kangerlussuaq
Alkaline Complex (20km west of Skaergaard), where they
uncovered mineralisation grading up to 2.5g/t Au, 1,583g/t
Ag , 7.7% Cu, 4.3% Mo, 10.1% Pb and 12.2% Zn. It is likely
that we will be flying a magnetic survey over this location
and then following up with further sampling and
mapping said the Exploration Manager.
In a location called Sortekap (roughly 40km NNE of
Skaergaard) gold grades of 1.0g/t to 2.7g/t were recovered
in 2009 sampling. This is a completely new discovery
and will be followed up with further sampling and
mapping concluded Mr.Abraham-James in the press
The Inferred Resource estimate for the Skaergaard
deposit, which includes the Palladium Zone, the Gold
Zone and the Combined Zone, was recently reviewed as
outlined in Table:

Advanced field programme completed
by True North Gems at
Fiskenæsset Ruby Project
On 6 October 2009,True North Gems announced that
the field-related components of the 2009 advanced exploration
and engineering programme have been completed
at the company's 100%-owned Fiskenæsset Ruby Project.
The strategic focus of the 2009 programme was the
acquisition of data required to support the company's
application for an exploitation (mining) licence to facilitate
subsequent test mining and test marketing.The field programme
began in late July and concluded in the first week
of September, successfully achieving the following objectives
according to Andrew Lee Smith, CEO:
True North's management believes the 2009 work programme
has provided valuable technical information that
will allow the company to advance towards its goal of submitting
an application for an exploitation (mining) licence
for the Fiskenæsset Ruby project in Greenland.

2009 Citronen field season drilling
Ironbark announced on 30 September 2009 that the field
season at its wholly owned Citronen base metal project(Citronen Fjord) has been successfully completed and all
drilling results have been received. Ironbark drilled 23 diamond
drill holes for a total of 2,345m, taking the total
metres drilled in the project to date to in excess of
46,000m in 204 drill holes. Drilling focused on obtaining
samples for metallurgical test work, geotechnical investigations.
Focus was also on confirming tenor and continuity
of high-grade zinc mineralisation in areas likely to be
mined early in the project life.The 2009 campaign builds
on Ironbark's 2008 field season drilling programme, which
focused on resource expansion and resulted in a 38%
increase in zinc metal content.
Drilling was completed on nominal 50m centres in the
shallow portions of the Beach Level 2 Zone.An area of
450 x 150 m was drilled – which equates to 4% of the
global resource.This area was selected as mineralisation is
shallow and representative of the global resource.
In addition to the increased confidence gained from
drilling, over 1,000 kg of mineralised material obtained
from drill holes was dispatched from the site.This material
is now at the Ammtec Burnie Research Laboratory in
Tasmania, where a feasibility level metallurgical test work
programme has commenced. Ironbark believes the information
obtained from this season's field work represents
a significant step forward for the project towards full feasibility
and ultimate production, concluded Jonathan
Downes, Managing Director.
The current JORC compliant resource for Citronen is as
101.7 million t at 4.7% zinc (Zn) + lead (Pb)
Indicated resource of 50.2Mt @ 4.5% Zn and 0.5% Pb
Inferred resource of 51.5Mt @ 3.8% Zn and 0.6% Pb
(Using Ordinary Kriging interpolation and reported at a 2% Zn cut-off).

NunaMinerals positive for new REEprospect
and the Storø gold-deposit
Promising REE analyses from the Maniitsoq
NunaMinerals has conducted reconnaissance prospecting
for Rare Earth Elements (REE) within the company's
Mantsoq licence.Two of 11 samples yielded 3.4% and 1.3%
REE (measured as oxides) from the locality Qeqertaasaq
which covers the well known Qaqqaarsuk carbonatite
NunaMinerals president and CEO Ole Christiansen said 2
December 2009: "These first assays from a modest reconnaissance
programme are a strong indication that the carbonatite
has the potential to host an economic REEdeposit.
The company now has the opportunity to look
for a partner for the continued exploration of this project."
The contents of lanthanum, cerium, praseodymium and
neodymium oxides in the two samples are 98% and 94%
of the Total REO respectively.The REEs are hosted in barium-
and strontium-rich carbonatite rocks.
The carbonatite at Qeqertaasaq was discovered by
Kryolitselskabet Øresund (KØ) in 1962 and described as
the Qaqqaarsuk carbonatite complex. It comprises an
inverted cone structure with ring dykes of carbonatite in
a 5 x 3 km wide oval pattern.The country rocks are
extensively altered (fenitised). During the 1960s and
1970s,KØ conducted exploration for REE and niobium.
Other companies and GEUS have also carried out exploration
and research in the area focusing on the niobium
and phosphate potential.
The Storø gold deposits to be drilled in 2010
In May 2008 NunaMinerals announced the results of the
first metallurgical studies on bulk samples from Qingaaq
on the island of Storø.
The metallurgical study showed that between 48% and
79% of the gold can be extracted by gravity alone and that
between 85% and 95% of the gold can be extracted by a
combination of physical and chemical processes.Additional
test work would optimise the recovery.
NunaMinerals and its partner, Nuukfjord Gold Mines Ltd,
expects to conduct diamond drilling during 2010 with the
aim of producing an initial resource estimate for the Main
Zone and the BD Zone at the Qingaaq prospect on
Storø.The resource estimate could lead to the preparation
of a preliminary economic assessment and to the
completion of a bulk sampling program in 2011.
