Newstrike Capital Reports Robust PEA on Ana Paula Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 15, 2014) -


Newstrike Capital Inc. ("NES" or the "Company) (TSX VENTURE:NES) reports the results of an independent technical report developed in accordance with CIM guidelines for a National Instrument 43-101 Preliminary Economic Assessment ("PEA") on its Ana Paula Project ("Ana Paula" or the "Project") located in the prolific Guerrero Gold Belt, Mexico. 

This study indicates that Ana Paula is a robust, high margin, rapid payback, 8.2-year open pit mining project that benefits from high gold grades with a low strip ratio. The Ana Paula project has excellent access to infrastructure and is located in an established mining jurisdiction.

The PEA study was prepared by JDS Energy & Mining Inc., under the direction of Thomas H. Bagan, Vice President, Project Development (Newstrike).

The reader is advised that the preliminary economic assessment summarized in this press release is only intended to provide an initial, high-level review of the project. The PEA mine plan and economic model include the use of inferred mineral resources which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the preliminary economic assessment will be realized.

All dollar amounts in this release are stated in US currency.


Base Case at $1,300 Au & $20 Ag per ounce

  • After-tax NPV@5% of $232.1million, IRR of 32.8% with a 2.4 year payback

  • Initial capital costs of $163.9 million (Total life-of mine ("LOM") - $219.7 includes sustaining/closure costs of $55.8 million and contingency costs of $36.2 million)

  • Open pit mine with 6,000 tonne per day ("tpd") gravity/flotation/CIL process plant

  • Cash costs of $527/ oz gold, $486/oz gold Net of By-Product credits

  • All-in sustaining costs ("AISC") of $567/oz gold, $526/oz gold Net of By-Product credits

  • Average annual production of 116,000 gold ounces and 239,000 silver ounces over a 8.2 year mine life

  • LOM average head grades of 2.24 g/t gold and 6.89 g/t silver

  • LOM gold and silver recoveries of 75% and 50%, respectively

  • LOM strip ratio of 2.60 to 1 of waste to mineralized material

"This PEA supports our view Ana Paula is one of the best development-stage gold projects in Mexico. It is a straightforward open pit mine, utilizing conventional milling and flotation concentration with robust economics. The combination of high gold grades, low capital requirements with low operating costs makes this a compelling development project," commented Richard Whittall, President and CEO of Newstrike. "With a positive PEA in hand, our next step is to evaluate the significant underground potential at Ana Paula and to support high priority exploration targets in this prolific gold belt." 

In management's view, the economics concluded by the PEA provide a strong incentive for continued geotechnical, metallurgical and engineering studies. Newstrike believes there are excellent opportunities to refine various project elements and improve the economics through gold recovery optimization.

As shown above, the Project has the potential to provide investors with commodity resilience as well as significant leverage to movements in the gold price.


The Ana Paula Project is located in the Guerrero Gold Belt in the State of Guerrero, Mexico, roughly half way between the cities of Mexico City and Acapulco. Mexico is a favourable jurisdiction for mining investment with clearly established mining law and regulatory due process as demonstrated by the existence of operating gold mines such as Goldcorp's Los Filos, located in close proximity to Ana Paula. Furthermore, Torex Gold's El Limon/Guajes Mine is currently under construction in close proximity to the Project. Ana Paula is close to all necessary infrastructure including water, road, power, and people.

Mining is via conventional open pit mining methods. Mining will be contracted so no capital is included for mining equipment, instead contractor mining rates used as the basis for mining costs.

Open pit mining costs were calculated from first principles based on equipment required and include pit and dump operations, road maintenance, mine supervision and technical services cost.


The PEA was independently prepared by JDS Energy & Mining Inc. ("JDS") of Tucson, Arizona. A technical report following the guidelines of the Canadian Securities Administrators' National Instrument 43-101 will be filed on SEDAR and on the Newstrike Capital's Inc. website within 45 days.

The PEA is based on a mineral resource estimate prepared by Independent Mining Consultants, Inc., Tucson Arizona, USA. This mineral resource estimate has been developed under the direction of Mr. H. E. Welhener. The resource is based on 223 diamond core drillholes aggregating 108,832 metres and containing 77,183 assay intervals, of which effectively all are assayed for gold and silver. The mineral resource estimate has an effective date of August 8th, 2014.

The tonnage and grades of the Ana Paula mineral resource* at a 0.46 g/t AuEq cutoff are shown in the table below:

*The resources are classified according to their proximity to sample locations and are reported, as required by NI 43-101, according to the CIM Definition Standards for Mineral Resources and Mineral Reserves.
Notes and assumptions:
1. Mineral Resources are not Mineral Reserves until they have demonstrated economic viability
2. Mineral Resources are reported as undiluted
3. Mineral Resources were developed in accordance with CIM (2010) guidelines
4. Mineral Resources are reported using a long-term gold price of $1,450/oz and silver price of $23/oz
5. Mining costs used are estimated at $1.85/ton plus $0.02/bench below 900m elevation 
6. Processing costs +general and administrative expenses are estimated at $17.25 per tonne
7. Gold recoveries are estimated at 80%
8. Silver recoveries are estimated at 55%. A silver divisor of 91.7 was used to calculate equivalent gold. (Silver is assumed to be recovered along with gold during processing.)
10. Pit slope angles are 55 degrees east-facing, 45 degrees west-facing
11. Resource QP is H. E. Welhener of IMC
12M&I = measured and indicated, Mt = million tonnes, g/t = grams per tonne, Moz = million ounces, Au = gold, Ag = silver, AuEq = gold equivalent
13. There can be no assurance that all or any part of this resource will be converted into a mineral reserve


The proposed project concept is to develop a green-fields gold-silver deposit with open pit mining and gravity/flotation/CIL process plant with a production rate assumed of 6,000 tonnes per day.

The PEA forecasts an 8.2 year mine life and a LOM strip ratio (the ratio of waste rock to economic mineralized rock) of 2.60 to 1. A total of 17.8 million tonnes of mineralized resource could be mined and processed with 33.6 million tons of waste and 12.5 million tonnes of capitalized waste. Some of the waste rock would be stockpiled and an undetermined portion may be reclassified as a resource at a later date should metallurgical testwork support economic viability. Throughout the life-of-mine, an estimated 957,000 ounces of payable gold and 2.0 million ounces of payable silver would be produced at an average head grade of 2.24 g/t gold and 6.89g/t silver. 


A metallurgical testwork program for the PEA was carried out on samples of composited drill core selected to represent the first four years of feed to the process plant. The composites were made from six rock types and subjected to direct cyanidation testing, flotation and gravity concentration followed by cyanidation, coarse particle leaching, and mineralogical deportment. The composite responded positively to both direct cyanidation and flotation concentration followed by cyanidation. Testwork was conducted by ALS Metallurgy in Kamloops BC and reported January 31st, 2014.

The flowsheet selected for Ana Paula consists of a tertiary crushing system, followed by ball mill grinding and gravity recovery, flotation, disposal of flotation tails, leaching of a combined gravity and flotation concentrate, and recovery of precious metals by the carbon-in-leach method. This flowsheet is commonly used throughout the world.


The project area is not within a known environmental protection area. Formal environmental baseline studies have not been initiated but will be required to obtain the environmental permits for future mining operations. Communication with the local community, private land owners and the "Ejido" (cooperative land tenure system) was initiated as part of the exploration program.
