Sanu Resources Ltd.: Eritrean Exploration Update

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Oct. 7, 2005) - Sanu Resources Ltd. (TSX VENTURE:SNU) (the "Company" or "Sanu") is pleased to provide an exploration update for Eritrea including a review of the last six months of work as well as exploration plans for coming field season.

- Through July 2005 (the start of the rainy season), the Company evaluated VMS prospects in Kerkebet and Mogoraib and gold prospects in the Guluj and Fanco, while at the same time conducting regional exploration. The work included drilling, soil and rock chip sampling, and ground EM and gravity surveys. Last season's field program was greatly impacted by the Eritrean work stoppage and significant delays due to mechanical and equipment issues in our drilling programs.

- As part of last season's program, the Company drill tested two VMS prospects (Bisha North and 1732) and two gold prospects (Melhoy and Wegeretai). Sufficient encouragement was encountered at Bisha North and Melhoy to continue drilling as part of this field season's exploration program. No additional work will be completed at this time on the 1732 anomaly and Wegeretai.

- Drilling has been initiated on the Company's portfolio of VMS prospects and will include testing of up to eight prospects. Currently, drilling is underway at Bisha North in Kerkebet where the Company has five to seven holes planned. A second core rig will be mobilized in three weeks to begin work in Mogoraib on the Ashelli prospect.

- Towards the end of October, the Company will mobilize a reverse circulation (RC) rig to evaluate four gold projects located on our southern licenses including the Melhoy Prospect where last year the Company intersected 17 meters of 2.76 grams per tonne (g/t) of near surface oxide gold mineralization.

- Regional exploration work will continue throughout the Company's entire land position (4,000 square kilometers). Regional exploration last year led to the discovery of three new VMS targets (Ashelli, Hambok, and Tekewda) as well as several early stage gold anomalies. We anticipate that the continued regional work will again lead to new exploration targets being generated.

- Initial results from the VMS drilling are estimated to be available within six to eights weeks while drilling results from the gold program (once initiated) will be released towards the end of the calendar year.

VMS Exploration Program - Central Licenses

Bisha North Prospect: The Company drill tested the Bisha North VMS prospect, located approximately 400 meters along strike from Nevsun Resource's Bisha Northwest prospect. The Company had planned to drill ten holes at Bisha North to test for massive sulfide mineralization, but for a variety of mechanical issues only three holes (BND-009, BND-004, BND-003) were completed for a total of 642 meters before the rainy season started.

Interpretation of the drill results suggests that drilling has intersected the alteration envelope and/or the distal facies of a massive sulfide system. BND-003 intersected a thick sequence of pyritic, sericite schist with intermittent zones of anomalous zinc between 60m and 200m. BND-009 intersected a thin massive sulfide horizon immediately overlying a rhyolite breccia unit, similar to the setting of Kuroko massive sulfide deposits of Japan. Results from the first three drill holes are encouraging in that strongly anomalous values occur within prospective host rocks where the principal targets (a significant residual gravity anomaly and a silica pyrite body) remain to be tested. Approximately 5 to 7 holes will be drilled at Bisha North during the current program.

Other VMS Prospects: The following table presents a summary of the VMS prospects located within the Kerkebet and Mogoraib Exploration Licenses. A majority of these prospects will be drill tested during this field season.

Gold Exploration Program - Southern Licenses

Melhoy Prospect: The Melhoy Prospect is located within the Hablesh-Demerayey trend of alluvial and quartz vein/shear zone. The Melhoy artisanal workings are developed on a north-south trending set of quartz veins hosted by ankerite-altered basaltic rocks. The veins extend for several hundred meters along strike and occur as a zone of en-echelon veins in the widest part of the prospect. The veins appear to die-out to the north and disappear under alluvium to the south. Chip samples from the veins yielded between 1-10 g/t gold. A trench across the widest portion of the vein swarm yielded 32m @ 1.3 g/t gold. Four holes were drilled at Melhoy with all holes being drilled toward the west (inclination -45 degrees). Significant assay results are shown below. The next round of drilling (start in October) will test the strike extensions of the mineralized zone and will include a minimum of 4 holes.

Qualified Person/Quality Analysis/Quality Control

Dr. Demetrius Pohl, a Qualified Person as defined by National Instrument 43-101 and Vice President of Exploration for the Company, has reviewed and verified the technical mining information contained in this news release. All drill core selected for assay was sawn in half in the field; one-half of the core was prepared for assay in Asmara, and the other half was stored on site. At Wegeretai, quartz vein and wall rock samples were treated differently in order to minimize potential nugget effects. Wegeretai wall rock samples, samples from the Bisha North and 1732, and samples from RC drilling were crushed and pulverized to -200 mesh at African Horn Laboratories in Asmara. The pulverized material was sent to Genlaysis Laboratories for 50 gm fire assay for Au and Ag and AAS analysis for Cu, Pb, Zn and Ni. Quartz vein samples (Wegeretai) were shipped in their entirety to Genalysis for screen fire assay. In this method, 500 g or 1 kg was split from the bulk pulp after initial pulverization with the split being re-pulverized to ensure the oversize portion is not excessive. The split was then dry-sieved through a 150 mesh nylon cloth. The coarse fraction was weighed, and the total coarse fraction, including the nylon cloth, was fire assayed in a new pot and the micrograms of gold determined. The remaining fines were homogenized and 25 g duplicate portions fire assayed and the gold determined in ppm. The "true" or "weighted mean" result was then calculated. High and low-grade standard samples and approximately 5% duplicate samples were randomly inserted throughout Sanu's drill core samples (except quartz vein samples for screen fire assay) for quality control.
