Soltoro Commences Deep Drilling on El Rayo Silver Property in Mexico

TORONTO, ONTARIO--(Marketwire - June 5, 2007) - Soltoro Ltd. (TSX VENTURE:SOL) has started the 3rd phase of diamond drilling on its El Rayo silver/lead/gold project in Jalisco, Mexico. The 3rd phase is designed to test priority airborne geophysical targets. Initial holes will test a geophysical anomaly covering a 1.5 km by 0.5 km area located adjacent to the main El Rayo mineralized structure. Approximately 1,800 metres of core drilling is planned for this phase. Soltoro is investigating the potential for El Rayo to host a bulk tonnage silver lead gold deposit. A total of 26 holes have been drilled to date to complete the 1st and 2nd phase of drilling. All samples from the 2nd phase have been submitted for assay and will be released once all results have been received.

Soltoro President Andrew Thomson reports: "The El Rayo property has never been drill tested to depth. Initial drilling will test a 1.5 by 0.5 kilometre airborne geophysical anomaly adjacent to the El Rayo structure. The majority of airborne geophysical anomalies being drill tested are located along the edge of an intrusive complex that extends for 12 kilometres. We are hopeful the geological information generated will also provide us with a better understanding of the relationship between the silver/lead and gold mineralization on the property."

On recommendation of the Company's analytical laboratory, Soltoro elected to re-assay a series of samples from historic mine workings, surface and near surface sites. Initial silver assays were obtained using Aqua Regia sample digestion and new assays were completed utilizing a 4 acid leach digestion process. In general terms, assay results were higher using the new preparation method with significant positive variation in values obtained. Further review of the relationship of 4 acid leach results to the mineralogy of samples will continue. Meanwhile, Soltoro has been using the 4 acid leach process for sample analysis during its current drilling campaign. The following table lists the most significant of the improved sampling results:

Aqua 4 Acid
Regia Leach
Width/ Silver Silver Silver Lead
Location/Zone Sample Type Metres gpt gpt Change %
Highway Zone Surface stockwork 34 35 63 80% 0.47
Matachines Mine Surface trench 1 10.5 39 78 100% 2.5
Matachines Mine Including 4.5 69 118 71% 2.9
Matachines Mine Surface trench 2 7.5 26 42 62% 1.6
Las Bolas Mine Underground 3 266 312 17% 3.13
Las Bolas Mine Underground 3 180 211 17% 2.16

The 34 metres of 63 gpt silver returned in the highway zone occurs on surface in a parallel structure approximately 500 metres south of the Las Bolas structure. The surface results from the Matachines mine are approximately 660 metres south-west of the Bolas mine on the Bolas structure. Soltoro obtained a core interval of 35.1 metres of 91.6 gpt silver at a 49 metres depth from surface at the Bolas mine (reported on May 4th 2007). A surveyor has been hired to provide a detailed topographic map in order to begin a second round of resource definition drilling.

Assaying of samples was conducted by ALS Chemex. Silver and other elements were analyzed using four acid "near total" digestion with an ME-ICP finish. Mr. William McGuinty, P.Geo, is the Company's qualified person as defined by NI 43-101 and has reviewed the contents of this press release.
