Soltoro Reports Revised NI 43-101 Compliant Silver Resource at the El Rayo Primary Silver Deposit in Jalisco

TORONTO, ONTARIO--(Marketwired - Sept. 29, 2014) - Soltoro Ltd. (TSX VENTURE:SOL) has received a revised independent resource estimate on its 100% owned El Rayo silver project in the State of Jalisco, Mexico. The NI 43-101 compliant resources were estimated by Agnerian Consulting Ltd. ("AC"), and includes an updated estimate of the Las Bolas deposit, the La Soledad deposit and a first time disclosure of the Mineral Resources of the historic Catarina mine. The revision considers a smaller tonnage, higher grade resource that could be exploited through a combination of small open pit and underground operations.

The Mineral Resources were prepared in compliance with NI 43-101 and CIM standards by AC by constructing block models and applying a conceptual open pit and underground models on each of the deposits. The estimates of open pit and underground resources are shown in the tables below:

(X1,000) Ag g/t Pb % (million oz) (million lbs) (million oz)
Las Bolas Indicated 1,560 139 0.47 7.0 16.1 7.4
Matachines Indicated 270 25 1.71 0.2 10.2 0.5
La Soledad Indicated 3,400 121 0.28 13.2 20.9 13.8
Total Indicated 5,230 121 0.41 20.4 47.2 21.7
Las Bolas Inferred 220 122 0.34 0.9 1.6 0.9
Matachines Inferred 70 52 1.15 0.1 1.8 0.2
La Soledad Inferred 370 104 0.34 1.2 2.8 1.3
Subtotal Inferred 660 104 0.43 2.2 6.2 2.4
Las Bolas Inferred 680 305 2.74 6.7 41.0 7.8
Matachines Inferred 60 91 16.70 0.2 22.0 0.8
La Soledad Inferred 120 215 1.04 0.8 2.7 0.9
Catarina Inferred 420 228 1.70 3.1 15.7 3.5
Subtotal Inferred 1,280 261 2.89 10.8 81.4 13.0
Total Inferred 1,940 208 2.05 13.0 87.6 15.4
1. CIM Standards were used to estimate Mineral Resources.
2. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental permitting, legal, title, taxation, socio-economic, political, marketing, or other relevant issues.
3. The quality and grade of the Inferred Mineral Resources are conceptual in nature and there has been insufficient exploration to define them as Measured Mineral Resources or Indicated Mineral Resources. It is uncertain if further exploration will result in upgrading the Inferred Mineral Resource to an Indicated or Measured category.
4. Silver Mineral Resources were estimated using the price of US$20/oz Ag. Only credits for the contained lead were assigned for the Las Bolas and Catarina deposits at price of US$0.90/lb.
5. Metallurgical recovery is assumed to be ranging from 15% to 65% of the contained silver for the Las Bolas, 75% of the contained silver for the La Soledad, and 60% of the constrained silver for the Catarina deposits. Metallurgical recovery for lead is assumed to be 69% for all of the deposits.
6. A minimum of 5m vertical thickness of mineralization was used for the zones of the open pit deposits.
7. The bulk density of mineralized rock is considered as 2.32 t/m3 (Las Bolas open pit), 2.57 t/m3 (Las Bolas underground), 2.45 t/m3 (Matachines open pit), 2.39 t/m3 (Matachines underground) 3.89 t/m3 (La Soledad open pit), 2.39 t/m3 (La Soledad underground), 2.42 t/m3 (Catarina underground).
8. Mineral Resources of conceptual open pits are estimated at a Net Smelter Return (NSR) cut-off value of US$13/tonne
9. Underground Mineral Resources are estimated at a horizontal thickness of 2m and an NSR cut-off value of US$65/tonne.
10. Tonnage and average grade numbers are rounded.
11. Catarina Mineral Resources include tonnage from past underground mining. Actual numbers will be different than the above estimates.
12. The calculation of the equivalent silver is based on metal prices above, the silver-to-lead ratio, and the recovery of lead in the mineralized material.

Soltoro President and CEO, Andrew Thomson comments: "The updated silver resources are in line with the lower silver pricing of the last two years and include lead along with revised metallurgical recoveries. This higher grade silver resource will allow Soltoro to move forward with completing a Preliminary Economic Assessment at current commodity pricings. Soltoro has only scratched the surface of the exploration potential in the Guachinango district. Agnico Eagle Corp. recently announced its plan to invest $15M on the nearby El Barqueño project, which is contiguous to the El Rayo property to the northwest."
