El Tigre Silver Announces Receipt of Tailings Recovery Environmental Permit in Sonora, Mexico

 

 

 

 

 

El Tigre Silver Corp. (TSX VENTURE:ELS)(OTCQX:EGRTF)(FRANKFURT:5RT) is pleased to announce that the Secretary of Environment and Natural Resources has approved the environmental plan that will allow development and construction of the El Tigre tailings recovery project effective July 18, 2013. This permit is the final step for the Company to accomplish and it can now proceed with its plans as outlined in a Preliminary Feasibility Study announced in a press release dated July 4, 2013 by Hard Rock Consulting, LLC.
 

SEMARNAT is a Mexican Executive branch, cabinet level agency that is responsible for developing environmental policy and permits for mining projects. In their review of the project’s environmental impact statement, they determined that by processing the historic tailings and placing them on lined containment, that it would eliminate an environmentally challenged area left from mining conducted from 1903 to 1938. They also determined that the Tailings Project would provide 60 direct and 85 indirect jobs in an area of Mexico that would welcome economic development. El Tigre is required to post US$34,870 reclamation bond before it can proceed with construction and it has to hire an environmental manager to ensure the company follows the terms of the permit.
 

The PFS on the Tailings Project contained in the Company’s news release dated July 4, 2013 is intended to provide a comprehensive technical and economic analysis of development options for the reprocessing of the tailings material. This study included detailed assessments of realistically assumed mining, processing, metallurgical, economic, legal, environmental, social, and other relevant factors needed to demonstrate the economic viability of the project. All data and interpretations are based on information available prior to the effective date of the PFS report of June 1, 2013. The projected internal rate of return from the reprocessing of the tailings is robust throughout a range of silver prices, increasing from 26.7% at a silver price of US$20 per ounce to 100% at US$35 per ounce.

Preliminary Feasibility Study of the Tailings:
 

The El Tigre Tailings Project contains 1.3 million tonnes of proven and probable tailings material grading 83.0 g/t silver and 0.279 g/t gold. HRC’s economic analysis of the base case utilized a silver price of US$25.00/oz and a gold price of US$1,289/oz at a silver to gold equivalency ratio of 51.57:1. Metallurgical recoveries for gold and silver averaged 93% and 78%, respectively, with projected mining costs of US$0.90 per tonne processed; processing costs of US$22.80 per tonne processed, and G&A costs of US$5.60 per tonne processed in a typical year. The mineral reserve estimate for the El Tigre Project is presented in Table 2.

(i)            Notes:

(1)Proven and probable reserves are based on assumed silver and gold prices of US$25/oz. and US$1,289/oz., respectively, metallurgical recoveries for gold and silver were assumed at 93% and 78%, and a mining, processing and G&A cost of US$29.30 per tonne processed.

(2) Mineral reserve tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.

(3)All reserves are stated above a 50 gpt Ag Equivalent cut-off.

(4)Silver Equivalent stated using a ratio of 60:1 and ounces calculated using the following conversion rate: 1 troy ounce = 31.1035 grams. Metallurgical recoveries are not accounted for in the silver equivalent calculation.
 

Highlights of the Tailings PFS

 



--  Ore is processed in a 400 ton per day mill and agitated cyanide leach
    plant with Merrill-Crowe recovery circuit over a 10 year operating life.
--  Base Case three year trailing average prices of US$25 per Ag ounce and
    US$1289 per Au ounce would generate an after tax net present value at 8%
    of approximately $10.7 million.
--  A Base Case after-tax rate of return of approximately 52.9%.
--  Projected salable production of 2.63 million ounces of silver and 10,500
    ounces of gold
 

 

 

The Tailings Project will require an overall initial and sustaining capital investment of $6.2 million, with a maximum envisioned cash injection of $4.0 million, with the remaining amounts provided by cash flow from operations.
 

The mineral resources and mineral reserve estimates are reported in accordance with Canadian Securities Administrators NI 43-101 and were estimated in compliance with generally accepted Canadian Institute of Mining, Metallurgy and Petroleum “Estimation of Mineral Resource and Mineral Reserves Best Practices” guidelines. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource will be converted into mineral reserves.
 

Stuart Ross, President and CEO commented: “Obtaining this critical permit is the culmination of a long term effort to develop the significant gold and silver resources found in the old tailings of the historic El Tigre Mine. The Company anticipates construction can begin later this year. Once production is started, we will have internally generated funds to move the project forward reducing future dilution and increasing shareholder value as we continue to expand the vein related resources with future drilling.”
 

The Project
 

The El Tigre Project is located in the Sierra Madre Occidental of northeastern Sonora, Mexico and is comprised of 8 concessions for over 431 square kilometers.
 

This mineral reserve estimate of the historic El Tigre Tailings Project was completed by Zachary J. Black, SME-RM an associate resource geologist with HRC, who has reviewed pertinent geological information in sufficient detail to support the data incorporated in the resource estimates. Mr. Black is an independent Qualified Person as defined under NI 43-101 and is responsible for the mineral resource and mineral reserve estimate presented in this release. Mr. Black has reviewed the content of this news release, and consents to the information provided in the form and context in which it appears.
