Scorpio Mining Announces Increased Mineral Resources and Contained Metals at San Rafael
Toronto, October 1, 2012 - Scorpio Mining Corporation (TSX:SPM) ("Scorpio Mining" or the "Company") today announced an independent updated Mineral Resource estimate for its 100% owned San Rafael Development Project in Sinaloa State, Mexico completed by Mine Development Associates of Reno, Nevada ("MDA").
Peter J. Hawley, Scorpio's Interim CEO commented: "The solid increase in the resource and upgraded categories of the San Rafael deposit acquired in the Platte River acquisition puts another development project in the pipeline for the Company's growth. Along with completed geotechnical studies and land access agreements, the new resources have moved this project closer to the development stage. San Rafael will enhance the Company's future, including the potential to develop a second processing operation in the Cosalá district."
The new resource estimation demonstrates an increase in tonnage and all contained metals compared to the resource estimate presented in November, 2009 as shown in Tables 1 and 2 below. Although a portion of this increase is due to higher metal prices, a large portion is attributable to increased drill density and confidence in the resource. In addition, the ratio of Measured to Indicated Resources increased from 26% to 35%.
At the reported resource cut-off of 1.5% zinc equivalent, the following changes in the new Measured and Indicated Resources were found:
Prices used to calculate ZnEq in 2009 were Zn=$0.80,Pb=$0.70, Ag=$12.00, Cu=$2.00 and Au=$750.00
Prices used to calculate ZnEq in 2012 were Zn=$0.85,Pb=$0.85, Ag=$24.00, Cu=$2.70 and Au=$1300.00
San Rafael is a skarn deposit related to a contact between calcareous sediments and overlying volcanic rocks. Mineralization occurs in three distinct zones: the Upper Zone characterized by moderate sulfide Ag-Au mineralization, the Main Zone which is characterized by high sulfide Zn-Pb ore with significant Ag, and the deeper structurally controlled, low sulfide 120 Zone characterized by Ag-Cu-Au mineralization. All of these zones contributed to the new resource model. A total of 141 new holes were drilled by the Company in 2011 and 2012 to upgrade and increase the resource at San Rafael.
General methodology used and details on the parameters of the Mineral Resource estimate are as follows:
Notes to Mineral Resource Statement:
The Mineral Resource estimate for the San Rafael Development Project was prepared by Mr. Paul Tietz, C. P. G. of MDA, who is a "Qualified Person", as defined in NI 43-101. Mr. Paul Tietz has reviewed and approved the contents of this news release with respect to the Mineral Resource estimates.
Quality Assurance and Quality Control
Scorpio Mining's Vice President of Exploration, Mr. James Stonehouse, is a Registered Geologist with the Society of Mining Engineers (Registration #4168919) and is a Qualified Person for this disclosure and has supervised the preparation of the technical information submitted to MDA which formed the basis for the updated Mineral Resource estimates disclosed in this press release.
Scorpio Mining's exploration programs are directly supervised by Mr. Stonehouse, and all technical information for the Corporation's projects is obtained and reported under a formal quality assurance and quality control (QA/QC) program. Data used in the updated Mineral Resource estimate comes from numerous drill programs conducted since 1999 and continuing to the present day. For purposes of this new Mineral Resource estimate, the QA/QC program was reviewed in terms of current standards and found to be adequate and typical of databases of this size.
For details of QA/QC procedures and results implemented for all exploration programs, reference should be made to the Company's website at www.scorpiomining.com.
Scorpio Mining is a silver producer operating in Mexico with significant base metal by-product credits. In addition, the Company has over 40 exploration targets mostly in the vicinity of its current operations.
The Company's 100% owned Nuestra Señora Mine and plant located in the Cosalá District of Sinaloa State, Mexico, has proven to be a low-cost operation with the benefit of flexible mining methods and diversified metal production. It has a fully mechanized underground operation and a processing facility built for expansion to 4,000 tonnes per day. The plant produces zinc, copper and lead concentrates with a significant silver component in the copper and lead concentrates. Scorpio Mining's strategy focuses on exploring and developing its existing mineral properties. At the nearby San Rafael and El Cajón deposits, an extensive diamond drilling program is in progress, with the goal of increasing the mineral resource base and ultimately an upgrade to reserve category.
Scorpio Mining also holds a 100% interest in the advanced, high-grade La Revancha silver and Tepozán silver-gold projects, both located in the productive Parral District within the respective states of Chihuahua and Durango, Mexico.
Cautionary Note to U.S. Investors:
Scorpio Mining reports its resource estimates in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to as NI 43-101. These standards are different from the standards generally permitted in reports filed with the SEC. Under NI 43-101, Scorpio Mining reports measured, indicated and inferred resources, measurements which are generally not permitted in filings made with the SEC. According to Canadian NI 43-101 criteria, the estimation of measured resources and indicated resources involve greater uncertainty as to their economic feasibility than the estimation of proven and probable reserves. Under SEC Industry Guide 7 criteria, measured, indicated and inferred resources are considered Mineralized Material. The SEC considers that in addition to greater uncertainty as to the economic feasibility of Mineralized Material compared to proven and probable reserves, there is also greater uncertainty as to the existence of Mineralized Material. U.S. investors are cautioned not to assume that measured or indicated resources will be converted into economically mineable reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources.
