Upgraded Mineral Resource classification and significant additional tonnages at IGE's Rönnbäcken Nickel Project, Sweden.
Upgraded Mineral Resource classification and significant additional
tonnages at IGE's Rönnbäcken Nickel Project, Sweden.
IGE Resources AB is pleased to present an updated Mineral Resource
Estimate carried out by SRK Consulting (Sweden) AB (SRK), for the
Rönnbäcken Nickel Project located in northern Sweden.
. The Project Mineral Resource now includes a total of:
o Measured and Indicated Mineral Resources of 257.1 million tonnes (Mt)
with an average total nickel content of 0.180% of which 0.110% is nickel
in sulphide (Ni-AC);
o Inferred Mineral Resources of 83.5 Mt with an average total nickel
content of 0.177% of which 0.103% is nickel in sulphide (Ni-AC).
. The above represents a significant increase to the previous Mineral
Resource Estimate prepared in April 2009, which included a total of:
o Indicated Mineral Resources of 54.9 Mt with an average total nickel
content of 0.187% of which 0.137% is nickel in sulphide (Ni-AC);
o Inferred Mineral Resources of 192.9 Mt with an average total nickel
content of 0.178% of which 0.107% is nickel in sulphide (Ni-AC).
. The resource upgrade will have a positive impact on the cost of the
Prefeasibility Study (PFS). The extent of further exploration and
infill drilling required has been reduced, thus lowering the overall
cost of the PFS by approximately USD3million to an estimated USD10.5
million to complete the PFS.
. Assuming that future exploration drilling succeeds in intersecting the
mineralised serpentinite body, SRK has suggested that an additional 40
to 80 Mt could potentially be added by drilling the down-dip extension
of the mineralised serpentinite at the Rönnbäcksnäset deposit and using
the parameters outlined in Table 1 below.
. In addition, results are pending from encouraging new exploration
drilling at Sundsberget, as reported in the press release on 6 April
2010. This drilling is entirely outside the Mineral Resources reported
here, lying within a 2km of Rönnbäcksnäset and having the potential to
add significantly to the overall Project Mineral Resources.
Fredric Bratt, CEO IGE Nordic AB, commented on the report stating: "The
update of our Mineral Resource Estimate by SRK adds additional tonnages,
but more importantly, has upgraded the Mineral Resource category
significantly reducing the amount of infill drilling required to
complete the planned Prefeasibility Study. Considering the improved
Mineral Resource Estimate, the potential for down-dip extensions at
Rönnbäcksnäset, the exploration potential at Sundsberget and satellite
deposits at Vinberget, our target of 400-450 million tonnes @ 0.10 to
0.15% Ni in sulphide should be achievable with the next round of
drilling."
The Mineral Resource Estimate was prepared by SRK Consulting (Sweden) AB
(SRK). The scope of work for this document was to produce a Mineral
Resource Estimate of the Rönnbäcknäset and Vinberget deposits. The two
assets form part of the Rönnbäcken Nickel Project. The report updates
the previous NI 43-101 compliant Mineral Resource Estimate of April 9,
2009. The new Mineral Resource Estimate report prepared by SRK will be
made available by the end of April 2010 at IGE Resource's website at
www.ige.se.
The Mineral Resource update undertaken by SRK utilized all available and
valid data as of April 10, 2010. The geological contacts to the
serpentinite body were remodelled and SRK extended the model at depth to
enable the evaluation of the down dip potential of the deposits. SRK
assumed a nickel price of USD9.00/lb in a whittle open pit optimisation
exercise to limit the material reported to that which SRK considers has
reasonable prospects for eventual economic extraction and applied a cut
off grade of 0.048% Ni-AC representing the calculated marginal cut off
grade for the deposits.
SRK considered that the low geological complexity, very homogenous
nature of the Ni-AC distribution, robust variograms, detailed
Quantitative Kriging Neighbourhood Analysis results and a drill spacing
within the geostatistical ranges observed were adequate to support the
reporting of Measured Mineral Resources for Vinberget and Indicated
Mineral Resources for Rönnbäcksnäset. The Mineral Resource Statement has
been classified in accordance with the Guidelines of National Instrument
43-101, and accompanying documents 43-101.F1 and 43-101.CP.

(1) The effective date of the Mineral Resource is April 21, 2010
(2) The Mineral Resource Estimate for the Rönnbäcksnäset and Vinberget
deposits was prepared using standard professional methods constrained
within serpentinite solids and within a Whittle pit shell defined by the
following assumptions; a marginal cut-off-grade of 0.048% Ni-AC, a metal
price of USD9/lb; slope angles of 52 degrees; a mining recovery of 95%;
a mining dilution of 2.5%; an average mine operating cost of
USD1.58/tonne (with a base case of USD1.00/tonne and an incremental mine
operating costs of USD0.07/tonne/10 metres below the 450 metre reference
RL and USD0.05/tonne/10 metres above the 450 metre reference RL);
process operating costs of USD4.24USD/tonne ore; an effective charge per
lb Ni in smelter feed of USD2.26 and G&A costs of USD1.00/tonne ore.
(3) Mineral Resources for the Rönnbäcksnäset and Vinberget deposits have
been classified according to the "CIM Standards on Mineral Resources and
Reserves: Definitions and Guidelines (December 2005) by Howard Baker
(MAusIMM) an independent Qualified Person as defined by National
Instrument 43-101.
The calculated waste to ore strip ratio from the Whittle optimisation
for the Rönnbäcksnäset deposit is 0.79:1 with a total waste tonnage of
217 million tonnes. The calculated waste to ore strip ratio from the
Whittle optimisation for the Vinberget deposit is 0.33:1 with a total
waste tonnage of 19 million tonnes.
The report titled "Mineral Resource Estimate for the Rönnbäcken Nickel
