Este diapositivo mostra el ubicacion de nuestras operationes en various partes del mundo
Nuestra estrategia es a continuar crecer una empresa diversificada.
Los beneficios de este estrategia son exemplificado por el cyclo recien con altos precios en carbon, era siguido en tiempo por cobre, despues zinc y mas tarde por plomo.
El resultado es a mantener ganacias sobre un periodo largo.
El ano pasado nuetro ganacias llegaron a 2.4 billion de dolares canadienses
Teck Cominco’s core strategy is to continue building a diversified mining company - and we have benefited in the last couple of years from this strategy. The company has enjoyed moving from commodity strength to commodity strength and as metallurgical coal prices rose then ebbed, copper prices escalated to new highs, then zinc prices took off, and finally, lead prices jumped to unparalleled highs. As a result, our company has enjoyed outstanding profit margins.

4. Red Dog, Alaska World’s largest zinc mine Production 2007 2008
by production & reserves
Reserves/ Resources life
>30 years
Production
Zn Production (t) , ,000
Pb Production (t) , ,000
Operating Profit (C$ million)
Ese es un photo de nuestra mina de Red Dog, lo mas grande mina de zinc en el mundo por production y reservas
Produce mas de media million tonneladas de zinc cada ano con ganacias en el ano pasado de uno punto uno billion de dolares.
Yo estuve en cargo de l’exploration alredor de la mina por quatro anos y puedo decir que tiene potential excellente a aumentar las reservas
Red Dog’s reserves and resources position should be good for at least 30 years more mine life, and there is outstanding exploration potential still in the region.
Production capacity at Red Dog is in range of 580,000 tonnes of contained zinc per year, and lead in the 100 to 120,000 tpa range.
Operating profit has improved dramatically this year with both higher zinc prices, and lower treatment charges paid to refineries.

5. Highland Valley, Canada
One of World’s largest tonnage copper mining / milling complexes
Production
Cu Production (t) , ,000
Mo Production (mlbs)
Operating Profit (C$million)
Highland Valley es un mina gigante de rajo abierto y tiene un vida de mina por lo minimo de 15 anos mas.
Las ganacias en 2006 eran un billion de dolares. El production bajara en el 2007 como un resultado de un ampilacion grande del rajo
97.5% interest
Reduction in Production in 07 due to major pushback and expansion

6. Elk Valley Coal, Canada
World’s second largest exporter of seaborne hard coking coal
Production
Coal Production (t) ,561, ,009,000
Operating Profit (C$ Million) ,226
En el sur oeste parte de Canada, un aerea muy sensitivo del punto vista del ambiente tenemos seis minas de carbon con ganacias significante en 2006.

7. Teck’s Approach to R&R Reporting
How we ensure consistency across multiple mines, commodities, and jurisdictions 7

8. Standard – NI 43101
Proven and Probable Mineral Reserves and Measured, Indicated and Inferred Mineral Resources are estimated in accordance with the definitions of these terms adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) in November 2005 and incorporated in National Instrument , “Standards of Disclosure for Mineral Projects” (“NI ”), by Canadian securities regulatory authorities. 8

9. NI History
NI was created after the Bre-X scandal to protect investors from unsubstantiated mineral project disclosures
It is now the cornerstone of R&R reporting in Canada
Teck personnel were involved in the formulation of the original CIM guidelines that underpin NI 9

10. R&R Team Paul Bankes, Director Reserve Estimation
4 people on his team with extensive R&R modelling/estimation experience
Reports to Reserve Committee of Management (includes division heads)
Which in turn reports to the Reserve Committee of the Board of Directors 10

11. Reporting Timetable

12. Resources to Reserves

13. Standardised Reporting From Each Operation

14. Standardised Reporting From Each Operation

Mine Design Parameters
Resource & Reserve Statement
R&R Change Tracking
Economic Test
Sensitivity Analysis 14

15. Signed Reports
R&R reports must be signed and dated by the site QP(s) and General Manager of Mine
~16 mines with up to 4 section QPs at each

16. In-house Audits
Regular audits of each mine site by Director Reserve Estimation or a member of his team
Reserve audit template in place

17. Summary and Conclusions
We have a strict definition of a Resource – must have “reasonable prospect for extraction”
Qualified Persons (QPs) are key – personally liable, must document results, efficient tracking of certification and consent
We have a Resource and Reserve committee of the board. Officers of the company take on significant responsibility 17
