Pan American Silver and Orko Silver Release Positive Preliminary Economic Assessment for La Preciosa Project
11.08.2011 | Marketwire
(All amounts in US dollars unless otherwise stated)VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/11/11 -- Pan American Silver Corp. (TSX: PAA) (NASDAQ: PAAS) ('Pan American') and Orko Silver Corp. (TSX VENTURE: OK) ('Orko') are pleased to report the positive results of a Preliminary Economic Assessment (the 'PEA' or the 'Assessment') for the La Preciosa Project (the 'Project' or 'La Preciosa'), located in the State of Durango, Mexico. Pan American and Orko are advancing the Project under a joint venture agreement by virtue of which Pan American can earn a 55% direct interest in the Project by bringing La Preciosa into production.
The PEA is preliminary in nature, in that it includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the PEA will be realized.
Highlights (all estimates are for 100% of the Project)
- Conventional surface and underground mining of 18 variably-oriented distinct vein structures.
- Estimated average annual production of 6.8 million ounces of silver and 11,800 ounces of gold at a cash cost(1) of $11.84 per ounce of silver, net of by-product credits.
- Mine life of 12 years.
- Pre-production capital and development costs of approximately $270 million.
- After-tax net present value at a 5% discount rate of $315 million (assuming prices of $25.00/oz silver and $1,250/oz gold).
- The Project generates a 24.3% IRR assuming the above metal prices.
- 5,000-tonnes-per-day conventional cyanide leaching plant producing a silver-gold dore.
1. Cash cost per payable ounce of silver is a non-GAAP measure. In addition to cost of sales, cash cost per ounce is a useful and complementary benchmark that investors use to evaluate performance and ability to generate cash flow and is well understood and widely reported in the silver mining industry. However, cash cost per ounce does not have a standardized meaning prescribed by Canadian GAAP as an indicator of performance.
Commenting on the Assessment, Mr. Geoff Burns, President and CEO of Pan American, said: 'La Preciosa is a very interesting Project, with a solid silver production profile, long mine life and it's located in a good mining jurisdiction, less than an hour's drive from our existing Mexican administration offices. At the PEA's long-term silver price the economics are very compelling; at current silver prices the Project is extremely robust. We will be moving forward aggressively to complete a full Feasibility Study and to position ourselves for a construction decision in the first half of 2012.'
Mr. Gary Cope, President and CEO of Orko commented: 'As we get closer to the Feasibility Study due by April 2012, we expect that the conservative estimates in the Preliminary Economic Assessment will demonstrate significant upside potential as questions and answers relating to mining methods and resources are refined. I am confident about the success of the project which at metal prices of $38.00/oz silver and $1,600/oz gold has a net present value of over $900 million and generates an internal rate of return of 52.7% with a payback period of less than 2 years.'
The PEA was prepared by Allan Earl, F.AusIMM, of Snowden Mining Industry Consultants, Michael Stewart, M.AIG of Quantitative Group, Joshua Snider, P.E. and Thomas Drielick, P.E. both of M3 Engineering & Technology Corp., and Gary Hawthorn, P.Eng. of Westcoast Mineral Testing, Inc.
Mineral Resource Estimate
A total of 18 variably oriented epithermal quartz veins and vein breccia systems have demonstrated sufficient geological continuity for estimation of Mineral Resources. The Mineral Resource estimate was updated with a new geological interpretation based on the results of 667 drillholes available at the end of October 2010. The drillholes are mostly arranged on an initial grid of 100 m by 100 m over almost the entire deposit and infilled in areas to 100 m by 50 m and in some areas to 50 m by 50 m. The estimated Mineral Resource contains 113 million ounces of silver classified as Indicated Mineral Resources and a further 46 million ounces of silver classified as Inferred Mineral Resources. In addition, the deposit contains over 222,000 ounces of gold classified as Indicated Mineral Resources and 83,000 ounces of gold classified as Inferred Mineral Resources.
A number of significant changes to the Mineral Resource estimate have taken place since the previous Mineral Resource estimate reported in March, 2009, including a 50% increase in the number of available drillholes, updated geological interpretations, consideration for likely minimum mining width requirements, mining dilution, an alternate resource estimation methodology, and different cut-off grades for resource reporting based on different metal prices, metallurgical recoveries, mining methods, and operating costs.
In comparing the Mineral Resource estimate disclosed in this release to the 2009 Mineral Resource estimate, at a 100 gpt Ag cut-off grade, this estimate represents a 45% increase in tonnes, a 17% decrease in silver grade, a 20% increase in contained silver ounces, a 14% increase in gold grade, and a 65% increase in contained gold ounces.
The following table summarizes the current Mineral Resource estimate for the Project:

----------------------------------------------------------------------------
(1) Mineral Resources that are not Mineral Reserves do not have demonstrated
economic viability. No Mineral Reserves have been estimated. Mineral
Resources have accounted for minimum mining width and planned mining
dilution.
The estimate of Mineral Resources may be materially affected by
environmental, permitting, legal, title, taxation, socio-political,
marketing, or other relevant issues, but no such issues have been
identified at this time.
Tonnes, grades, and ounces have been rounded and this may have resulted in
minor discrepancies in the totals.
The division between open pit and underground resources is set on a
horizontal level at the 1920 m elevation, which is considered close to
optimum at the metal prices and operating costs assumed in this Assessment
(2) Cut-off grades are based on operating cost estimates and metal prices of
$25/oz silver and $1,250/oz gold. Metal prices are based on a weighted
average of historical three year average daily silver prices and a two year
future price forecast.
(3) Silver equivalent grade values assume a gold to silver ratio of 50 to 1
based on the assumed metal prices. The metallurgical recoveries and
refining charges are assumed to be the same for silver and gold for the
purposes of the equivalence calculation only.
----------------------------------------------------------------------------
Production, Infrastructure and Processing
The Assessment estimates that a total of 16.6 million tonnes of ore classified as Indicated Mineral Resources and 5.6 million tonnes of ore classified as Inferred Mineral Resources will be mined at an overall average grade of 137 gpt silver and 0.26 gpt gold. Mining methods have been selected for each vein based on the thickness and dip of each vein. For each mining method selected there are assumptions with respect to mining costs, minimum mining height, and mining recovery. The selected mining methods and other assumptions may change during the course of future studies as more data regarding vein geometry, geotechnical stability, and other mining parameters is gathered. The deposit will be extracted using both open pit and underground mining. Open pit mining will be undertaken using conventional truck and shovel methods and underground mining will be primarily by room and pillar, with backfill as required for shallow dipping veins,along with some shrinkage stoping for steeply dipping veins. The optimum mine plan includes three open pits producing a nominal 2,000 tonnes of ore per day at an average strip ratio of 15:1 and an underground mine producing a nominal 3,000 tonnes of ore per day. As a consequence of increased knowledge of the deposit as mining progresses, actual mining may result in reduced mine dilution, costs and possible improvements in mining recoveries in excess of those that have been assumed in the PEA.
The Project is located 84 km by road northeast of the city of Durango. The PEA anticipates constructing a new 9.7 km long road to reduce the travel time to access the site from Durango. The water required to run the processing plant is expected to be sourced from a new water well potentially located 7.2 km to the east of the Project. Energy for the Project is expected to be supplied by a proposed 41 km long power line leading to a sub-station located northwest of the Project.
Environmental baseline data has been collected for a full year during 2010 and 2011 to define the current conditions in and around the proposed mine site and will be used to produce the Environmental Impact Assessment ('EIA'), which will be submitted as required for permitting. It is anticipated that this EIA will be presented to the Mexican government for approval once the necessary surface rights are secured, likely within the next six to nine months. It is believed that the necessary permits could be obtained to allow for the start of construction in the second half of 2012.
The PEA envisages the construction of a 5,000 tonne-per-day plant comprising primary crushing, grinding, cyanide leaching, followed by cyanide neutralisation, Merrill Crowe processing, refining, and conventional pulp tailings disposal facilities. The life-of-mine average silver and gold recoveries are estimated at 86% and 78%, respectively. Further metallurgical test work is planned in order to verify and potentially improve these recoveries.
Capital and Operating Costs
The total capital and pre-production expenditures to bring La Preciosa into production have been estimated at approximately $270 million. Capital and operating costs have been calculated in 2011 US dollars with an assumed escalation of capital during the construction period of 2.4%, or $6.4 million. The following table summarizes the estimated initial capital costs, which exclude sustaining capital, but include 20% contingency for plant costs, 22% contingency for Owner's costs, and 15% contingency for the other items shown in the following table. No contingency has been applied for escalation of plant and engineering, procurement, and construction management costs (EPCM). The total estimated contingency is $41.8 million. Sustaining capital over the remainder of the mine life is estimated at $115.7 million, which is made up of $90.2 million for underground and open pit mining fleet replacement and $25.5 million for owner's costs, which include such items as non-plant engineering, environmental activities including reclamation, communications and security, insurance, water rights purchases, land purchases and leases.
