EMC Metals Corp. (the “Company” or “EMC”) (TSX: EMC) is pleased
to announce promising results from field exploration work on the Tørdal
property during the summer and fall months of 2012, focussed on
scandium-bearing pegmatites.
The 2012 work included independent assay results of pegmatite rock
samples taken from one specific property area, and also includes an
extensive pegmatite mapping program covering approximately 30 sq km. The
assay results indicated the presence of high levels of scandium and
various rare earth elements (REE’s), including heavy rare earth elements
(HREE’s) in particular. Field XRF readings indicated elevated scandium
content in hundreds of large and small pegmatite bodies found and mapped
in the reconnaissance area.
Highlights:
-
Tørdal 2012 assays of pegmatite rocks show presence of both
scandium and REE’s,
-
Best scandium assays exceed 1,600 ppm,
-
Promising HREE assay results from pegmatites with gadolinite
mineralization,
-
Host rock mineralization points to higher grade scandium or HREE
contents,
-
2012 summer exploration program mapped and sampled over 300
pegmatites,
-
A total of 1,940 Niton XRF scandium readings were taken on whole
rock samples, and
-
Overall program results at Tørdal very encouraging; warrant
expanded exploration.
Discussion—Norway Exploration Programs
Assay
Results of Grab Samples at Tørdal
EMC previously released the
soil sample assay results of its 2011 summer exploration program on the
Tørdal property, which consisted of reconnaissance, surface soil
sampling, and limited pegmatite mapping work in a relatively small area
north of the village of Kleppe, in Southern Norway.
As a follow-on from that 2011 program, the company then returned to the
same area and conducted a series of ‘blasts’, using small explosive
charges to generate whole rock samples on select exposed pegmatites, at
the locations of the best soil sample results. The exploration team
planned 9 blasts and conducted 8, on 5 different pegmatite bodies, from
which they assembled 23 grab samples for analysis and assay by OMAC
Laboratories in Ireland. Assay results on these samples were received in
Q1 2012—in time to help formulate the 2012 summer/autumn season
pegmatite mapping program, conducted on a much wider area.
Independent assay results on 20 of the 23 samples, covering all 5
targeted pegmatites, are shown below.

NOTE: All blast samples taken from Kleppe area (Area 1), total of 5
unique pegmatites

Assay results are as-reported elemental assay results from OMAC
Laboratories, and are not converted to oxide
equivalent (REO
& Sc2O3). Heavy
rare earth elements abbreviated “HREE”; and include Yttrium;Total rare
earth elements abbreviated “TREE”.
The numbered assay samples were formed either by random selection of
fresh (un-weathered) whole rock material broken loose from individual
pegmatite bodies, or alternatively, based on selectively collecting
fresh rock material that was clearly (1) garnet-laden, (2) mica-laden,
or showed clear visible (3) gadolinite mineralization. Gadolinite is a
beryllium and rare earth-bearing mineral with the chemical formula
[(Ce,La,Nd,Y)2FeBe2Si2O10].
The intent was to determine from assay results if certain visible
mineralization correlated to the presence and concentrations of target
elements; specifically scandium, rare earth elements (REE’s), or other
metals of interest and value.
The results in the assay table indicate that all of the selected
pegmatites contain interesting levels of both REE’s and scandium. In
general, all of the pegmatites contained both target elements, while the
mica phase appears to hold the higher scandium concentrations with small
REE additions, and the gadolinite phase holds the highest REE
concentrations and small scandium additions. The presence of garnet
material in samples tended to generate interesting but moderate values
for both REE’s and scandium. Assay work was designed to identify 30
specific elements, including all 16 REE elements plus scandium, and the
relative concentration of heavy REE’s was of particular interest. The
mica and garnet grab sample materials had generally only trace levels of
thorium and uranium (average <15 ppm), while the gadolinite grab sample
materials had thorium levels between 2,500-5,000 ppm, and uranium levels
between 500-1,300 ppm. A full table of OMAC assay results related to
these 23 sample analyses will be available on EMC’s website.
Reconnaissance Results – Extended Pegmatite Mapping Program at Tørdal
Following
on from the 2011 work and the 2012 assay results, EMC conducted an
expanded 2012 summer work reconnaissance program at both Tørdal and
Evje-Iveland, from July through October. The goals of the 2012 program
were to develop detailed mapping of outcropping pegmatite fields over a
much broader area than the 2011 program, while also conducting field
sampling of scandium mineralization on those pegmatites using a
hand-held Niton XRF Analyzer.
The 2012 program concentrated on five separate areas (approximately 30
sq km) as can be seen in the map below:
To view the map, click onto the following link:
http://www.usetdas.com/maps/emcmetals/emcmetalsfeb14006.jpg
A total of 1,940 Niton XRF readings were logged on whole rock and
pegmatite mineral separates, logged against individually mapped and
numbered pegmatite bodies. The XRF readings ranged up to +6,000 ppm
scandium (on a mineral separate), and averaged 661 ppm on 1,504 total
logged readings above the instrument’s 20 ppm detection limit. XRF
readings focussed on scandium data collection only, although the team
diligently noted the visible presence of gadolinite and amazonite
mineralization.
The reader is cautioned that hand-held Niton XRF readings are not the
same as laboratory assays, and are not NI 43-101 compliant with regard
to estimating resource grades. However, the Company is confident that
these data readings are highly useful in confirming and shaping the next
stage of the exploration program on this property.
A summary of results by area is as follows:
-
Area 1 (Kleppe). Mapped more than 50 pegmatite bodies. Best
average XRF Sc readings from 1,000-1,500 ppm, some very large surface
expressions. Gadolinite present.
-
Area 2 (Heftetjern); Partially mapped more than 40 pegmatite
bodies, many large surface expressions, green amazonite
mineralization. Better XRF Sc readings from 500-1,500 ppm.
-
Area 3 (Solli); Mapped numerous large and small pegmatites.
Generally lower XRF Sc readings, ranging 300-700 ppm. Red feldspars,
quartz and gadolinite mineralization present.
-
Area 4 (South Kleppsvatn); Partially mapped large area
containing more than 80 pegmatites, generally mica-based. Typical XRF
Sc readings in the 300-900 ppm range, with some reaching 1,500 ppm Sc.
-
Area 5 (Buvatn); Partially mapped, numerous pegmatite bodies,
some very large. Typical XRF Sc readings in the 300-1,000 ppm range.
Old feldspar quarries, amonizite mineralization present.
Similar work done at Evje-Iveland (total 180 sq km) identified several
interesting target areas, but scandium readings were not sufficiently
attractive when compared to results at Tørdal. These observations led to
the decision to drop Evje-Iveland, as part of an amended agreement which
also enabled EMC to achieve an immediate 100% earn-in on Tørdal. (see
EMC press release dated January 17, 2013 announcing early earn-in
agreement with REE Mining).
The exploration results of the 2012 work program also allowed EMC to
selectively reduce property holdings at Tørdal in January 2013. The
property has been reduced from 140 sq km to 90 sq km, with lower ongoing
exploration license holding costs as a result.
Next Steps in Norway Exploration Program
EMC’s mapping and
sampling work has confirmed that much of the Tørdal property is heavily
populated with complex, near-surface pegmatite bodies. Based on
hand-held XRF readings and mineralogy, these pegmatites show excellent
promise for significant scandium enrichment, particularly within bodies
containing micas, and for REE mineralization where the rare earth
silicate gadolinite is present.
In 2013, EMC’s exploration program plans include the following:
-
Small bore drill program to test select pegmatite depth, size, and
continuity, both of target mineralization within individual
pegmatites, and similarity of mineralization between various
pegmatities in defined areas, or fields,
-
Drill core assay program to gain lab-assay reportable resource grades
from core material, for scandium and REE, to support grab sample assay
work done to date,
-
Bench scale material testing work to determine if the resource may be
amenable to simple concentration techniques (gravity concentration,
magnetic separation, and limited flotation processes, particularly on
micas), and also to field separation of various target minerals,
-
Further geologic work to correlate scandium and REE presence within
various host minerals in the pegmatites, specifically micas,
feldspars, quartz, gadolinites and amazonites, and
-
Identify individual pegmatite fields that favor either scandium or REE
resources, based on identified host mineral occurrences.
Qualified Person and Quality Assurance/Quality Control
Sampling
methods followed industry quality control standards. Mr. Kjell Nilsen,
an independent geologist consultant currently employed by EMC, conducted
the reconnaissance and sampling on the property. Individual whole rock
grab samples were collected by hand shovel, from areas where blasted
material could be seen to have come from blast points on pegmatite
bodies. The assayed samples were individually bagged, sealed, logged on
the grid map as to location, boxed in a container suitable for mailing,
and sent by express mail to OMAC Laboratories Limited in Galway, Ireland
for testing. Assay testing on the samples utilized an ICP-MS
spectrometer (Inductively Coupled Plasma-Mass Spectrometry) to test for
numerous elements, specifically scandium. The numerous Niton XRF (X-ray
Fluorescence) readings were taken at field locations, logged and
identified with individual numbered pegmatites, located on grid maps, by
the field geology team. Mr. Willem Duyvesteyn, Chief Technology Officer
of EMC, is the Qualified Person who is responsible for the design and
conduct of the exploration program, and reviewed the program results.
Mr. George Putnam, CEO of EMC Metals comments:
“We are
pleased to complete the early 100% earn-in on the Tørdal property,
enabling us to focus our budgets on resource development, and to now
identify an exciting target area within the property holding, based on
work results. The 2012 summer work program has further convinced us that
Tørdal is a very attractive near-surface discovery prospect for both
scandium, and also REE mineralization. The target shows the right
combination of potential scandium and REE grades, size, access, and
simplicity of production potential, and we intend to now focus our
Norway exploration attention here in 2013.”
