Soltoro finds new gold zone at El Rayo

SOLTORO IDENTIFIES ADDITIONAL GOLD ZONE AT THE EL RAYO PROJECT

Soltoro Ltd. has identified a new gold zone on its 100-per-cent-owned El Rayo project located in Jalisco, Mexico. The newly identified Tierra Blanca gold target is located along the western concession boundary of Soltoro's El Rayo project and extends onto Agnico Eagle's El Barqueno property. Anomalous gold mineralization occurs in a series of west-northwest-trending zones of argillic alteration containing varying amounts of subparallel quartz veining or silicification. Alteration zones are up to five metres in width containing individual zones of veining up to one metre in width. To date, eight chip samples have been collected from exposures in the area yielding values ranging from nine parts per billion gold to 161 parts per billion gold (0.161 gram per tonne gold) with seven of the eight containing greater than 10 parts per billion gold and two containing greater than 100 parts per billion gold. Anomalous gold is associated with sporadic, low-level anomalies in arsenic, silver, bismuth and molybdenum.

Andrew Thomson, president and chief executive officer of Soltoro, stated: "The newly identified Tierra Blanca gold zone further evidences the widespread nature of precious metals mineralization in the Guachinango district. A follow-up sampling program is being designed to further assess this target."

The Tierra Blanca area is believed to represent the eastern extension of the Poncho and San Diego mineralized trends on Agnico Eagle's adjacent El Barqueno property. Gold values of 120 grams per tonne gold and 8.34 grams per tonne gold have been reported from the Poncho East target, located approximately 1,500 metres to the west of Tierra Blanca (Cayden Resources presentation dated Sept. 8, 2014). Mineralization at Poncho East is hosted by the same rhyodacitic sequence as the mineralization at Tierra Blanca, while much of the mineralization occurs in the underlying andesitic epiclastic rocks.

Mineralization at Tierra Blanca is hosted by rhyodacitic epiclastic rocks. Geologic mapping indicates that this unit overlies andesitic epiclastic rocks, which are known to be favourable host rocks on both the El Rayo and El Barqueno properties. On both properties, mineralization may extend upward into the base of the rhyodacitic unit. Based on preliminary field investigations, andesitic (and basaltic andesite) epiclastic rocks are present 40 metres to 60 metres below the rhyodacitic rocks exposed at Tierra Blanca, suggesting that a drill target may be present in the more favourable andesitic rocks at a shallow depth.

In addition to anomalous gold values in rock, Soltoro identified a separate weak antimony soil anomaly with weakly anomalous gold samples at either end of the anomaly. The anomaly is located approximately 400 metres north of the Tierra Blanca area, trends east-west and measures approximately 500 metres in length. The anomaly is open to the east on the El Rayo property and to the west. There is little outcrop in the area, but one sample collected from near an anomalous soil sample did not yield detectable gold. Further work, including trenching will be required to test the areas around the anomalous gold samples.

Qualified persons

Steven T. Priesmeyer, CPG, is vice-president, exploration, for Soltoro. He is a qualified person as defined by National Instrument 43-101, and he has reviewed the geological contents of this press release. Analytical work is performed by ALS Chemex. Samples are submitted to the ALS sample preparation facility in Guadalajara and pulps are shipped by ALS to its laboratory in Vancouver, B.C., for analysis. Analytical procedures include a 33-element ICP-AES analysis (ME-ICP61m) and a 50-gram FA AA finish for gold (AA-24). Silver assays exceeding 100 grams per tonne are reassayed by hydrochloric leach with an ICP-AES or AAS finish (OG62).

Assay quality assurance and quality control

Soltoro's standard quality assurance/quality control program consists of the systematic insertion three different standards representing high, medium and low grades, a field duplicate, fine and coarse duplicates, and fine and coarse blanks into the sample stream. Standards and fine blanks are purchased from CDN Resources Laboratories Ltd. in Vancouver, B.C. Fine and coarse duplicates are selected by the field geologist and inserted into the sample stream by ALS Chemex. The coarse blank is unmineralized volcanic rock obtained locally. Control samples are inserted on the basis of 50 sample batches.

Certified reference materials are plotted against the mean and standard deviation based on the sample analyses from the primary laboratory. A standard is considered to have failed if it exceeds the mean plus three standard deviations or if two consecutive standards from the same batch exceed the mean plus two standard deviations. A failure of a control standard triggers an investigation into the cause. A blank failure is defined by a reported value above three times detection limit of the method.
