*New geochemical and geological surveys
*Old Adit sampling yields encouraging results

Toronto, Ontario, Canada, June 27, 2007: Sulliden Exploration Inc. (“Sulliden” or the “Company”) (TSX: SUE) reports the following update on the current exploration program on its 100% owned Shahuindo gold property in Peru, where a recent geochem survey has outlined a new gold zone and sampling of old adits and pits has returned high precious metal values in both quartz-vein and breccia style mineralization.

     Location and previous work

Sulliden’s Shahuindo gold-silver project is located in northern Peru, in one of the world’s most prospective gold and silver regions, and sits approximately 25 km north of Barrick’s Laguanas Norte-Alto Chicama 1,100,000 oz/gold per year mine; 70 km south of Newmont’s multi-million oz/gold Yanacocha district and 200 km north of Barrick’s Pierina 650,000 oz/gold per year mine.

In 2003 and 2004 Sulliden conducted field work, surveys, geophysics and two drilling programs on the property consisting of 83 diamond drill holes totaling almost 12,000 metres. The drilling by Sulliden in 2003 and 2004 was very successful in substantially increasing the size of the resource on the Shahuindo property. In the period since 2002 up to April 30, 2007 Sulliden has invested $19,375,000 in exploration and development costs on the Shahuindo property, including legal costs incurred to defend Sulliden’s ownership of Shahuindo but not including the property acquisition costs.

The Shahuindo resource now stands at 38 million tonnes grading 0.95 g/t Au and 22.99 g/t Ag, containing 1.2 million oz of gold and 28 million oz of silver (equivalent to 1.6 million oz of gold at a gold to silver ratio of 1:60) in the Indicated Category; and 17.2 million tonnes grading 0.62 g/t Au and 12.83 g/t Ag, containing 342,000 oz of gold and 7 million oz of silver (equivalent to 460,000 oz of gold at a gold to silver ratio of 1:60) in the Inferred Category - (Resource Estimation – Guy Saucier: Met-Chem Canada Inc. April 2005 filed on www.sedar.com).

The existing resource is principally centered on the San Jose deposit, which extends within the Shahuindo property concessions for more than 3 km in strike and up to 75 meters in width 100 metres in depth and is open in all directions. The San Jose gold mineralization lies at the northern contact of totally argillized Mezosoic quartz-feldspar porphyry body with some lower Cretaceous sedimentary rocks consisting of quartzite, siltstone and shale. Gold mineralization is generally associated with brecciated quartzite and siltstones. Gold mineralization has also been located underneath the known oxidized San Jose zone as a large disseminated sulfide zone.

     2007 Shahuindo Exploration Program

Following the issuance to Sulliden of an Exploration Permit by the Ministry of Energy and Mines of Peru, on April 17, 2007 (see Sulliden Press Release dated April 23, 2007), Sulliden has implemented an extensive exploration program on the Shahuindo property. The following is a brief description of the work and results obtained so far:

     Geochemical soil survey outlines new gold zone

In the first part of May 2007, Sulliden started a new geochemical soil survey to cover part of the Shahuindo property that has never been sampled before. The survey first covered an area located to the Northeast of the main San Jose zone, in a region where Sulliden had previously delineated a ground magnetic anomaly similar to the one associated with the San Jose zone. Usually, these magnetic anomalies are associated with Porphyry type intrusives crosscutting the sedimentary assemblages.

So far, a total of 166 soil samples taken over approximately 17.4 km of surveyed lines have been collected. Gold values of up to 2.0 g/t Au in the soil were obtained in a well defined NW-SE oriented area that has been followed on 8 lines so far (spacing of 100 meters between lines) and is still open in both directions. This anomalous “envelop” (values higher than 100 ppb Au) is directly overlying the formerly outlined magnetic anomaly. Follow up work is planned to test this newly discovered gold anomaly.

     Adit Sampling yields encouraging results

A total of 140 samples have been collected from 68 old underground adits and small pits. These adits and pits are distributed over a strike length of more than 4.0 km to the West and North-West of the western limit of the known San Jose mineralization. This area has never been explored previously by Sulliden and no drill holes have ever tested these old workings. Each sample was collected by channel sampling and has a minimum length of half a meter to up to 1.5 meters. Analyses were done for various elements and other metals such as for Au, Ag, Cu, Zn, Pb and As. The analyses for the adits and pit sampling program were carried out by ALS Chemex Laboratories in Lima, Peru. Check assays are being carried out at SGS Laboratories in Lima. Fire assays for gold were performed on 50 grams of pulp with AA finish with gravimetric finish for samples above 10g/t. Aqua Reggia digestion was used for silver with AA finish.

High grades of gold (up to 38 g/t Au) and silver (up to 2750 g/t Ag) were obtained. In fact, of the 140 samples taken, 17 of them, taken from 12 different adits or pits, returned values higher than 10 g/t Au. Moreover, 112 samples (i.e. 80%) are above 0.1 g/t Au of which 82 (58%) returned values higher than 0.5 g/t Au. Two very different types of mineralization have been identified. One consisting of Quartz-vein type and the other Breccias type. High precious metal values were obtained in both environments.

All of the gold-silver bearing samples are confined in a well defined West- Northwest corridor that strikes for more than 4.0 additional kilometers from what seems to be the extension of the main San Jose zone. Of particular significance, however, is that this mineralized corridor appears to be extending into the Chimu Formation instead of the Caruhaz Formation that hosts the San Jose zone. Barrick’s Norte-Alto Chicama gold mine, located just 25 km to the north of Shahuindo, is precisely hosted in this same Chimu Formation.

     Ground Geophysics survey underway

In early June 2007, Sulliden started a new geophysical magnetic ground survey that has covered about 31 km of a 99.35 km planned survey. The survey area is located to the North and Northwest of the San Jose Zone to test an area that had not been covered by Sulliden previously. Approximately 17.8 km of this 99.35 km campaign is programmed for the Vikingo adjacent property which is under option by Sulliden and on which no significant work has previously been carried out. The geophysical survey should be completed by mid July.

     Access roads and infrastructure

Most of the access roads leading to the Shahuindo property, and to Sulliden’s camp, have been re-opened and repaired where necessary after a difficulty rainy season which caused some local damage. This work was carried out by Sulliden using local community labor. Sulliden has also launched a water monitoring program.

     Comment

Management of Sulliden is very pleased and excited about the results obtained so far from the 2007 exploration program at Shahuindo and are also very optimistic about the future follow-up drilling campaign. The results of this new exploration phase will help to confirm the priority of the outlined targets for the next drilling campaign. The high gold and silver values obtained from the rock and soil sampling in areas that have never been evaluated in the past by Sulliden demonstrate the important exploration potential of Sulliden’s Shahuindo property which could eventually add to the known gold and silver resources.
