"Please read our cautionary notes to investors before proceeding."


The following are important notices for all investors regarding the information contained on this website. Please read these Cautionary Notes carefully and thoroughly.

Trevali's production plans at Halfmile-Stratmat, Caribou and Santander are based only on Indicated and Inferred Mineral Resources and not Mineral Reserves and do not have demonstrated economic viability. Inferred Mineral Resources 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 therefore no certainty that the conclusions of the production plans and Preliminary Economic Assessment (PEA) will be realized. Additionally where Trevali discusses exploration/expansion potential, any potential quantity and grade is conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

Santander resource estimate was completed by Golder Associates in July 2012. The tabled resource estimate utilizes a 3% zinc equivalent (ZnEQ) cut-off and is based on the Ordinary Kriging interpolation method and Silver, Lead, Zinc and Copper assay values. Minor capping was applied to the assays prior to estimation. The bulk density was also estimated using Ordinary Kriging. The tonnages for the footwall zones are also included, but those for the tailings are not included. The average interpolated bulk density for Magistral North was 2.88 g/cm3, Magistral Central 2.94 g/cm3, Magistral South 2.97 g/cm3, Puajanca South 2.76 g/cm3, and Santander Pipe (fixed) 3.4 g/cm3. The density of the minor footwall zones is similar to the Magistral zones. The contained oz and lbs in the table are in situ and have not had mill factors applied to them.

Santander ZnEQ = ((Ag Price(g) x Ag Recovery x Ag Grade) + (Pb Price(t) x Pb Recovery x (Pb Grade(%)/100)+(Zn Price(t) x Zn Recovery x (Zn Grade(%)/100)))/Zn Price(t). Golder utilized the US dollar three-year rolling average price for all three metals. Price for silver is ($25.99/oz) and that for Pb ($2,205), Zn ($2,094) and Cu ($7,782) is per tonne. A recovery of 85% was applied to Ag, 90% for Pb, 85% for Zn and 60% for Cu for calculating the ZnEQ formula. The pounds of metal are in-situ and have not had any mining factors applied to them.

Halfmile-Stratmat PEA was completed by Tetra Tech Wardrop in October 2010. The resource estimate utilized a 5% zinc equivalent (ZnEQ) cut-off. The following metallurgical recoveries were applied to the ZnEQ for the resource estimate: 89.7% zinc (Zn), 72% lead (Pb), 60% copper (Cu), and 48.6% silver (Ag).

Caribou resource estimate was completed by SRK Consulting (Canada) Inc. in January 2013. The tabled resource estimate utilizes a 5% zinc equivalent (ZnEQ) cut-off grade. ZnEq=((Cu Grade*Cu Price*Cu Recovery)+(Pb Grade*Pb Price*Pb Recovery)+(Zn Grade*Zn Price*Zn Recover)+(Au Grade*Au Price*Au Recovery)+(Ag Grade*Ag Price*Ag Recovery))/Zn Price. In calculating ZnEq, SRK Consulting (Canada) Inc. utilized the long term metal prices provide by Energy & Metals Consensus Forecast. Price for Au is $1470 per ounce, Ag is $26 per ounce, Cu is $3.39 per pound, Pb is $1.18 per pound, and Zn is $1.14 per pound. A recovery of 83% was applied to Zn, 71% was applied to Pb, 57% was applied to Cu, 45% was applied to Ag, and 40% was applied to Au. The pounds of metal are in-situ and have not had any mining factors applied to them.

Ruttan resource estimate was completed by Tetra Tech Wardrop in February 2008. The resource estimate utilized a 1% copper equivalent (CuEQ) cut-off.

Forward-Looking Statements

This discussion and disclosure on this website contains forward-looking statements within the meaning of Section 27A of the United States Securities Act and Section 21E of the United States Securities Exchange Act of 1934 concerning the Company's plans for its properties, operations and other matters. These statements include, without limitation, statements regarding future anticipated property acquisitions, the cost, timing and content of future exploration programs, anticipated exploration program results, the discovery and delineation of mineral deposits/resources/reserves, business and financing plans, potential mining scenarios, the success of mineral processing procedures, business trends and future operating costs and revenues and may relate to analyses and other information that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management. Information concerning mineral resource estimates also may be deemed to be forward-looking statements in that it reflects a prediction of the mineralization that would be encountered if a mineral deposit were developed and mined. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as "expects" or "does not expect", "is expected", "anticipates" or "does not anticipate", "plans", "estimates", "believes" or "intends", or stating that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved) are not statements of historical fact and may be "forward-looking statements". Forward-looking statements are subject to a variety of risks and uncertainties, which could cause actual events or results to differ from those reflected in the forward-looking statements, including, without limitation:
  • risks related to zinc, lead and silver prices and other commodity price fluctuations;
  • risks and uncertainties relating to the interpretation of drill results, the geology, grade and continuity of mineral deposits;
  • risks related to the inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses;
  • results of initial feasibility, prefeasibility and feasibility studies, and the possibility that future exploration, development or mining results will not be consistent with the Company's expectations;
  • mining and development risks, including risks related to accidents, equipment breakdowns, labour disputes or other unanticipated difficulties with or interruptions in production;
  • the potential for delays in exploration or development activities or the completion of feasibility studies;
  • the uncertainty of profitability based upon the Company's history of losses;
  • risks related to failure to obtain adequate financing on a timely basis and on acceptable terms;
  • risks related to environmental regulation and liability;
  • risks related to hedging activities;
  • political and regulatory risks associated with mining and exploration; and other risks and uncertainties related to the Company's prospects, properties and business strategy.

Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Forward looking statements are made based on management's beliefs, estimates and opinions on the date the statements are made and the Company undertakes no obligation to update forward-looking statements if these beliefs, estimates and opinions or other circumstances should change. Investors are cautioned against attributing undue certainty to forward-looking statements.

Readers are cautioned that the assumptions used in the preparation of such information, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, undue reliance should not be placed on forward-looking statements. The actual results, programs and financial position of Trevali Mining Corporation could differ materially from those expressed in or implied by these forward-looking statements, and accordingly, no assurance can be given that the events anticipated by the forward-looking statements will transpire or occur, or if any of them do so, what benefits the Company will derive therefrom.

All of the Company's Canadian public disclosure filings may be accessed via SEDAR at www.sedar.com and its United States public disclosure filings may be accessed via EDGAR at www.sec.gov and readers are urged to review these materials, including the technical reports filed with respect to the Company's mineral properties.

Cautionary Notes to US Investors

This website may also contain information with respect to adjacent or similar mineral properties in respect of which the Company has no interest or rights to explore or mine. The Company advises US investors that the US Securities and Exchange Commission's mining guidelines strictly prohibit information of this type in documents filed with the SEC. Readers are cautioned that the Company has no interest in or right to acquire any interest in any such properties, and that mineral deposits on adjacent or similar properties are not indicative of mineral deposits on the Company's properties.

This website and other information released by Trevali Mining Corporation may use the terms "resources", "reserves", "inferred resources", "measured resources" and "indicated resources". United States investors are advised that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Mineral resources that are not mineral reserves do not have demonstrated economic viability. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves. Inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist, or that they can be mined legally or economically.

National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all reserve and resource estimates disclosed in this web site or in other information released by Trevali Mining Corporation, have been or will be prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") Standards on Mineral Resource and Mineral Reserves, adopted by the CIM Council on November 14, 2004 (the "CIM Standards") as they may be amended from time to time by the CIM. United States investors are cautioned that the requirements and terminology of NI 43-101 and the CIM Standards differ significantly from the requirements and terminology of the SEC set forth Industry Guide 7. Accordingly, the Company's disclosures regarding mineralization may not be comparable to similar information disclosed by companies subject to the SEC's Industry Guide 7.

National Instrument 43-101 Disclosure


National Instrument 43-101 - Standards of Disclosure for Mineral Projects is a rule developed by the Canadian Securities Administrators, and applicable throughout Canada, which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects materials to the issuer. Trevali Mining Corporation adheres to the NI 43-101 standards, and provides the following information related to its Peruvian projects.

The work programs at the Company's Peruvian properties have been designed and are run by EurGeol Dr. Mark D. Cruise, a qualified person as defined by National Instrument 43-101, who has supervised the preparation of the scientific and technical information that forms the basis for the disclosure with respect to the results of exploration on the Company's Peruvian projects as contained on this website. Dr. Cruise is the President and Chief Executive Officer of Trevali Mining Corporation, and is therefore not independent of the Company.

All geochemical samples are secured and shipped to ALS Chemex for assay. For properties where drilling is taking place, on-site personnel at the project photograph the core from each individual borehole prior to preparing the split core, which is then sealed and shipped to ALS Chemex for assay.

ALS Chemex's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by the use of international and in-house standards. Finally, representative blind duplicate samples are forwarded to ALS Chemex and an ISO compliant third party laboratory for additional quality control.
