VANCOUVER, BRITISH COLUMBIA announces new NI 43-101 compliant
independent resource estimates for the Debarwa copper-zinc-gold and
Adi Nefas zinc-gold-copper volcanogenic massive sulphide (VMS)
deposits on its 100% owned Asmara Project, Eritrea. Most of the
resources in both deposits have been upgraded to the Indicated
category as well as a significant increase in size and grade at Adi
Nefas from the initial independent resource estimates for the Adi
Nefas and Debarwa deposits released in January 2007.
Combined with the recently announced resources on the Company's
Emba Derho property the total combined metal in the Indicated
category defined on the Asmara Project is:
- 2.3 billion pounds of zinc
- 1 billion pounds of copper
- 872,000 ounces of gold
- 27 million ounces of silver
Note: Contained metal estimates remain subject to factors such
as mining dilution and process recovery losses.
The Debarwa deposit is located approximately 30 kilometres south
and Adi Nefas about 8 kilometres north of the capital city of
Asmara and both have excellent infrastructure including paved
roads, power, water, an international airport and an international
sea port only 120 kilometres away by paved road. In addition, Adi
Nefas is located only 6 kilometers away from the large Emba Derho
zinc-copper-gold deposit for which Sunridge recently announced the
initial resource estimate (see location map below).

HIGHLIGHTS
Debarwa Deposit
- The Debarwa Deposit has a rich supergene copper zone with an
average grade of 5.36% copper using a 1% copper cut-off, containing
158 million pounds of copper in the Indicated category.
- The deep primary zone at Debarwa, which is open at depth, has
an average grade of 2.53% copper with 3.23% zinc in the Indicated
category using a 1% copper cut-off and contains an additional 39
million pounds of copper and 49.8 million pounds of zinc.
Adi Nefas Deposit
- The Adi Nefas deposit's average grade of the primary zone,
using a 2% zinc cut-off, has increased to 8.38% zinc, 2.85 g/t gold
and 99.36 g/t silver containing 504 million pounds of zinc, 250,000
ounces of gold and 9 million ounces of silver.
- These resource estimates for both Debarwa and Adi Nefas are
mostly in the "Indicated" category.
Asmara Project:
- Sunridge now has four mineral deposits on the Asmara Project
with NI 43-101 reported resources; these are Emba Derho, Adi Nefas
and Gupo Gold deposits within 6 kilometres of each other and the
high-grade Debarwa Deposit located 30 kilometres to the south.
Note: Detailed tabulations of the resources for these deposits
as well as details of resource estimate methodologies are appended

The resource estimates for Debarwa and Adi Nefas were completed
by MSA Geoservices Ltd., ("MSA"), an independent and
internationally operating geological consultancy firm based in
Johannesburg, South Africa in accordance with National Instrument
43-101 requirements. The resource estimate dated January 21, 2008
was carried out by Graham Greenway of MSA and audited by Mike Hall,
MAus IMM, an independent Qualified Person as defined by National
Instrument 43-101.
The Company will file a NI 43-101 Technical Report regarding the
Debarwa and Adi Nefas resource estimates within 45-days of the date
of this news release. The Company filed the Emba Derho NI-43-101
Technical Report on the Company's profile on www.sedar.com on
January 16, 2008.
Debarwa Resource Estimate Methodology
The Debarwa deposit is a copper/zinc/gold/silver volcanogenic
massive-sulphide (VMS) deposit that has been defined by Sunridge in
277 drill holes over a total combined strike length of over 1,000
metres. The deposit has an average width varying between 8 to 30
metres dips between 50 and 60 degrees to the west and has been
drilled down to a depth of about 250 metres from surface. The
resource estimate was completed by MSA using industry standard
methods in accordance with National Instrument 43-101 requirements
and used Datamine modeling software. The estimate was based upon
data from 277 diamond and reverse circulation drill holes (total of
32,530 metres) and a geological model supplied to MSA by Sunridge
geological staff. The geological model created by Sunridge staff
used 20 and 40 metre cross-section spacings. Ordinary kriging was
used to estimate grades into blocks with dimensions of 10 metres
(easting), 12.5 metres (northing) and 5 metres (RL), subsequently
sub-divided to half of these figures. The search ellipsoid
dimensions and directions chosen for the grade interpolation
process were metal and zone specific. Minor grade caps were applied
to the gold, silver, copper and zinc values during block grade
estimation to limit the influence of high grade outliers.
Specific gravities used in the model were based on 710 specific
gravity measurements made on drill core. Block density values were
assigned to the oxide zone using the nearest neighbor technique
using a combination of density measurements and average
lithological densities. In the supergene and primary zones block
model density values were assigned using a regression formula.
Adi Nefas Resource Estimate Methodology
The Adi Nefas deposit is a zinc/gold/copper volcanogenic
massive-sulphide (VMS) deposit that has been defined by Sunridge in
96 drill holes over a total combined strike length of 450 metres.
The deposit has an average width of approximately 6 to 12 metres,
dips between 70 and 80 degrees to the east and has been drilled
down to a depth of about 350 metres from surface. The resource
estimate was completed by MSA using industry standard methods in
accordance with National Instrument 43-101 requirements and used
Datamine modeling software. The estimate was based upon data from
96 diamond drill holes (total of 18,424 metres) and a geological
model supplied to MSA by Sunridge geological staff. The geological
model created by Sunridge staff used 40 metre cross-section
spacings. Ordinary kriging was used to estimate grades into blocks
with dimensions of 7.5 metres (easting), 10 metres (northing) and 5
metres (RL) and subcelled to 3.75 metres by 5.0 metres by 2.5
metres. The search ellipsoid dimensions and directions chosen for
the grade interpolation process were metal and zone specific.
Specific gravities used in the model were based on 280 specific
gravity measurements made on drill core. Block density values were
assigned to the oxide and supergene zones using the nearest
neighbor technique using a combination of density measurements and
average lithological densities. In the primary zone block model
density values were assigned using a regression formula.
DISCLOSURE NOTES:
1. A Quality Assurance/Quality Control program was part of the
drilling program on the Debarwa and Adi Nefas deposits. This
program includes chain of custody protocols as well as systematic
submittals of standards, duplicates and blank samples into the flow
of samples produced by the drilling. The database archive used by
MSA Geoservices Ltd. in the estimate of the resources at Debarwa
and Adi Nefas were reviewed and verified by Mike Robertson, a
Qualified Person as defined by NI 43-101.
2. A description of the geology, sampling procedures, and the
Company's laboratory Quality Assurance/Quality Control procedures
will be described in NI 43-101 Technical Report that will be filed
within 45 days of the date of this release. This report will then
be available at www.sedar.com.
3. Samples from the drilling were prepared at African Horn
Testing Services (Eritrea) and analyzed at Genalysis Laboratories
(a NATA registered laboratory) in Perth Western Australia.
4. The results of the MSA resource estimate have been reviewed
by Sunridge technical staff including Michael J. Hopley the
Qualified Person for Sunridge. The Company believes that the MSA
resource estimate for Debarwa and Adi Nefas was conducted in a
professional and competent manner. Mr. Hopley is also the person
responsible for preparation of the technical information contained
in this news release and is President and Chief Executive Officer
of Sunridge.
5. Inferred Resources are resources that have not been defined
in sufficient detail to be characterized as Measured or Indicated
Resources. Mineral resources have not had economic considerations
applied to them and are therefore not characterized as
Reserves.
