SOLTORO INTERCEPTS 6

SILVER AT EL RAYO PROJECT
Soltoro Ltd. (SOL:TSX.V) has
completed a 5,530 metre orientation diamond drill program at the El Rayo project
in Jalisco, Mexico which is being investigated for the presence of a bulk
tonnage silver lead gold deposit. Drilling in the final phase of the program
tested priority geophysical targets and extensions to mineralized structures
along strike from the property?s historic silver-lead resource area. This phase
was modified to investigate previously untested zones of mineralization along
strike from the known resource area resulting in only 4 of 14
priority airborne geophysical targets being drill tested.
Andrew Thomson, the
President of Soltoro, reports: ?We are extremely encouraged by the latest drill
results as widths and grade of the mineralized zones at depth are sufficient to
support both open pit and underground mining for gold and silver. These new
zones fall outside of the property?s historic resource area and have seen little
to no exploration nor drilling previously. To date, Soltoro has defined 5
kilometres of mineralized structures open on strike to the north east and north
west.?
El Rayo North West Structure: Prior trenching along the
north west
extension of the 2.4 kilometre El Rayo structure identified a previously unrecognized gold zone with an 825 metre strike length. Four drill holes were
completed from 3 separate locations along this extension. The most significant results reported from these 4 holes
are presented in the table below and include a silver equivalent value based on
a silver to gold ratio of 55:1 (US $660 and $12.00 for gold and silver
respectively):

Las Bolas North East
Structure:
Drilling and trenching along the north east extension of the 800 metres Las
Bolas structure has extended the mineralized strike length of the structure an
additional 900 metres for a total strike length of 1,700 metres. Two drill holes
were completed below the Arturo and Ernesto Mines along this extension.
Significant results were returned as follows:

Diatreme
zone: Drill hole 28 tested the centre
of airborne geophysical Anomaly 25, a 700 metre
long by almost 400 metre wide magnetic low
1,150 metres north of the Catarina mine, situated
between the El Rayo and Las Bolas structures. This area has never been prospected, mined or drill
tested as it is covered by overburden for the most part.
The hole intercepted what is believed to be
an intrusive matrix diatreme from 12 metres
to 467 metres
and terminated without exiting diatreme material. Drill hole
28 returned anomalous gold and silver values as follows:

Chris Lloyd, the Vice President of Exploration reports:
?The discovery of an igneous matrix diatreme breccia of a style similar to the
Pe?asquito Deposit in northern Mexico is an exciting development at
El Rayo and represents a new target style and potentially significant area. While only one interval returned
anomalous values in this hole, a wide interval of over 200 metres was noted with
strong silicification and disseminated pyrite indicating a hydrothermal fluid
has affected this intrusive body. At the Pe?asquito Deposit the better mineralized areas are associated with faulting, fractures and zones of
silicification along the periphery of the breccia body. These peripheral zones
could represent the best drill targets for mineralization and remain to be
tested.?
Soltoro is conducting more detailed mapping and sampling
programs on the diatreme and the Rayo gold zone, including a topographic survey.
The Company is reviewing and compiling data prior to designing a resource
definition drill program at Rayo and new work in several other areas such as the
Diatreme zone. Meanwhile, the Company is focusing its efforts on the Bacanora
bulk tonnage gold project in Sonora, where drilling is now underway.
A summary of results and
maps detailing features of the orientation drill program are available at the
company?s website: www.soltoro.com
All diamond drilling at the
El Rayo project is being carried out using HQ diamond core. Assaying of samples
was completed by ALS Chemex through their office in Guadalajara, Mexico. Silver and other base and
trace elements were analyzed using four acid ?near total? digestion with an
ME-ICP finish. Gold was analyzed using a 30g fire assay with AA finish. Internal
standards provided by an independent company and locally derived blank samples
are being inserted for quality control purposes. Mr. William McGuinty, P.Geo, a
director of the Company and qualified person as defined by NI 43-101 has reviewed the contents of this press release. Field supervision of the El Rayo
project is provided by Mr. Chris Lloyd, Vice President, Exploration.
Soltoro is a junior exploration company active in
Mexico with 19,638,600 shares
outstanding. The Company is exploring for bulk tonnage gold, silver and copper
deposits in Mexico. Shares trade on the TSX
Venture Exchange under the symbol SOL.
