SOLTORO COMMENCES DEEP
DRILLING ON EL RAYO SILVER PROPERTY IN MEXICO
Toronto, Ontario: Soltoro
Ltd. (SOL:TSX.V) 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 Companys 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

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,
