Soltoro Drilling Intercepts 91.3 Metres of 129 gpt Silver Equivalent Including 11.2 Metres of 537 gpt Silver Equivalent in a Massive Sulphide Zone
Soltoro Ltd. (TSX VENTURE:SOL) has completed three additional diamond drill holes at the El Rayo primary silver project in Jalisco, Mexico. A 350 metre-deep hole was completed below the Las Bolas deposit and two holes were completed north of the La Soledad West deposit. At Las Bolas, 91.3 metres of 129 g/t silver equivalent was intersected including 11.2 metres of massive sulphide mineralization grading 537 g/t silver equivalent encountered 318.8 metres down hole. The deep hole at Las Bolas extends mineralization 70 metres down-dip from the nearest hole with a substantial increase in silver grades. At La Soledad, 0.3 metres of 3,320 g/t silver was returned extending the known high grade silver mineralization an additional 60 metres down dip.
At Las Bolas, the upper portion of the 91.3 metre mineralized intercept consists of a sulphide-poor quartz-hematite stockwork typical of the mineralization found to date in the Las Bolas deposit. The last 11.2 metres of mineralized interval intercepted a massive silver-bearing quartz-galena zone occurring in the footwall of the stockwork zone. In the following table, results are presented for the entire mineralized interval followed by results for the stockwork zone and then the sulphide zone:

| (2) | AgEq - Silver equivalent includes Au, Ag and Pb and excludes Cu & Zn. |
| Assuming 100% metallurgical recovery, pricing is as follows: Au - US$1,675/oz.; Ag - US$31.30/oz.; Pb - US$1.00/lb. |
Andrew Thomson, President and C.E.O. of Soltoro Ltd., stated: "The presence of silver-rich massive sulphides at depth below the Las Bolas deposit provides Soltoro with a significant opportunity to define additional silver resources at Las Bolas. To date the Company has been primarily focused on defining open-pittable silver resources at El Rayo. In the short term three additional drill holes are being completed to the north, south and below drill hole Ray 12-152 to further test the scope of the sulphide mineralization at depth and along strike."
The presence of a sulphide-rich zone near the base of the typically sulphide-poor Las Bolas stockwork zone requires further investigation. On completion of the three planned drill holes, Soltoro will have better clarity as to the relationship of the sulphide-poor stockwork-type silver mineralization and the massive sulphide mineralization. These holes will also assist in defining the extent of this sulphide-rich mineralized zone.
At La Soledad drill holes RAY11-150 and RAY11-151 were completed to test the down-dip extension of high-grade silver intersections encountered in diamond drill holes RAY11-148 and RAY11-149. Hole deviation problems, caused by a strong north-south-trending fault zone, prevented hole RAY12-150 from reaching its intended target. Hole RAY12-151 successfully encountered mineralization assaying 0.3 metres of 3,320 g/t silver further demonstrating the high-grade silver nature of the La Soledad West zone:
| DEPOSIT AREA | DRILL HOLE | FROM | TO | DRILLED WIDTH (1) (m) |
Ag (g/t) |
| La Soledad | RAY12-151 | 216.85 | 217.70 | 0.85 | 1,236 |
| including | 216.85 | 217.15 | 0.30 | 3,320 |

Assaying from this program was completed by ALS Chemex through their office in Guadalajara, Mexico. Gold was analyzed using a 30g fire assay with AA finish while the silver is analyzed using a four acid "near total" digestion package, lead overlimits were analyzed using volumetric titration.
