Sunridge Gold Announces Indicated Resource Estimate for Emba Derho VMS Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 4, 2007) - Sunridge Gold Corp. (TSX VENTURE:SGC) announces an initial NI 43-101 compliant independent resource estimate for the Emba Derho zinc-copper-gold volcanogenic massive sulphide (VMS) deposit, on its 100% owned Asmara Project, Eritrea. This estimate is almost entirely in the "Indicated" category, with the total combined Indicated resources in the primary zinc and copper zones containing 1.7 billion pounds of zinc, 735 million pounds of copper, 402,000 ounces of gold and 15 million ounces of silver. The deposit is still open, particularly to the northwest. The estimate meets the Company's stated objectives in terms of size, average grade and the potential for a large open-pit operation. Emba Derho is located approximately 12 kilometres northwest of the capital city of Asmara and has excellent infrastructure including paved roads, power, water, an international airport and an international sea port only 120 kilometres away by paved road.

Michael Hopley, President and CEO of Sunridge Gold states, "We are very pleased with the rapid progress of this project, from the discovery of Emba Derho in January 2006 to the completion of this NI43-101 compliant Indicated resource today. The fast tracking of the project is due in large part to strong support from the Ministry of Energy and Mines of Eritrea in an area with some of the best infrastructure associated with any development project in the world today."

HIGHLIGHTS

- The Emba Derho deposit hosts 2 distinct primary base metal zones which have resources reported separately:

1. Zinc Rich Zone - The currently defined Indicated resource in the primary zinc-rich zone is 27.9 million tonnes grading 2.52% zinc, 0.46% copper, 0.36 g/t gold and 11.51 g/t silver, using a cut-off of 1.0% zinc.

2. Copper Rich Zone - The currently defined Indicated resource in the primary copper-rich zone is 21.2 million tonnes grading 0.96% copper, 0.36% zinc, 0.12 g/t gold and 6.74 g/t silver, using a cut-off of 0.5% copper.

- This initial resource estimate is almost entirely in the "Indicated" category.

- Ongoing drilling at Emba Derho outside the main zone is expected to add significantly to this resource.

- Metallurgical test work on material from Emba Derho has shown that the primary zinc-rich and copper-rich sulphide material responds well to flotation with recoveries of zinc and copper greater than 90% and the final zinc concentrate exceeding 60% zinc and the final copper concentrate greater than 30% copper.

- Sunridge now has four mineral deposits on the Asmara Project with NI 43-101 reported resources; these are Debarwa, Adi Nefas, Gupo Gold and now Emba Derho.

Emba Derho Resource Estimate Methodology

The resource estimates 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 November 30, 2007 was carried out by Mike Hall, MAus IMM, an independent Qualified Person as defined by NI 43-101.

The Emba Derho deposit has three distinct zones of mineralization, a surface oxide gold zone from which most base metals have been leached; underlain by a primary sulphide zone of zinc-rich mineralization (Primary Zinc) which is in turn underlain by a copper-rich primary sulphide zone (Primary Copper). Theses zones are shown graphically in the diagram, http://www.ccnmatthews.com/docs/1204sun.pdf. (Due to this zonation of mineralization the resources have been reported according to the following cut-off scenarios, all of which, it is anticipated, will be mined by open-pit methods.)

- 0.5 g/t gold cut-off for the upper oxide zone,

- 1.0% zinc cut-off for the underlying Primary Zinc zone, and

- 0.5% copper cut-off for the deeper Primary Copper zone.

The Emba Derho deposit is a zinc/copper/gold/silver volcanogenic massive-sulphide (VMS) deposit that has been defined by Sunridge in 179 drill holes over a strike length of 1,000 metres, a width of approximately 400 metres and 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, utilizing Datamine modeling software. The estimate was based upon data from 179 diamond drill holes (total of 46,168 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 10 m (easting), 10 m (northing) and 5 m (RL). The search ellipsoid dimensions and directions chosen for the grade interpolation process were metal and zone specific. Minor grade caps were applied to the precious metals during block grade estimation to limit the influence of high grade outliers.

Specific gravities used in the model were based on 827 specific gravity measurements made on drill core. Block density values were assigned to the oxide zone using the nearest neighbor technique and to the primary zone using a regression formula applied to Cu, Pb, Zn and Fe block grades.

The Company will file a NI 43-101 Technical Report regarding the Emba Derho resource estimates within 45-days of the date of this news release.

Emba Derho Metallurgy

A total of eighteen metallurgical tests including two locked-cycle tests have been completed on representative samples of the primary sulphide zinc-rich mineralized material and the primary sulphide copper-rich mineralized material from Emba Derho. The results show that this material responds very well to the flotation process with recoveries of zinc and copper greater than 90% and the zinc final concentrate exceeding 60% zinc and the final copper concentrate greater than 30% copper. No metallurgical testwork have yet been completed on the upper oxide gold zone.

Additional Resource Potential

The foregoing Indicated and Inferred resource estimates do not include an additional 18 drill holes completed since the resource estimate was prepared. Some of these drill holes, particularly to the northwest of the main Emba Derho deposit, have shown intersections up to 116 metres of massive-sulphide mineralization. The Emba Derho northwest zone has been drill tested for over 400 metres along strike and is still open for another 600 metres based on the surface geology, gravity, and pulse EM (electromagnetic) data. Management believes that these recent results will have the potential to increase the size of the Emba Derho resource.

In addition, the Company has three other deposits on its 100% owned Asmara Project which are the Debarwa copper/zinc/gold VMS deposit, the Adi Nefas zinc/gold VMS deposit and the Gupo Gold deposit. The Adi Nefas and Gupo gold deposits are located less than 6 kilometres from Emba Derho deposit. Newly estimated Measured and Indicated resources for Debarwa and Adi Nefas are expected from MSA within one month.
