Two very advanced projects in Mexico as well as numerous other exploration interests. Has been active in Mexico as Teck almost 13 years now. In 1995 exploration was carried out on 20 properties, six of which were drilled. Of those 6, three deserved further work in 1996. Primary targets were porphyry Cu, polymetallic skarn and Au-Ag deposits. ('96 Annual Report). In 1997 there were 3 major projects in the Annual Report (Nukay, another Au project  and San Nicolas). Teck also participates indirectly in Mexico by taking a position in other major and junior companies active there. For example by acquiring 100% of Cominco Ltd. who has been active in Mexico for a long time through Cia. Minera Constelación S. A. de C. V. (recently re-named Cominco Mexico). Also by controlling 14.2% of Silver Standard Resources (as of 10Jun98 - CMH '98-'99) and over 13% of Western Copper. Teck enjoys indirect participation with several other properties. Another example is of a typical arrangement is the 1992 deal with Northern Crown Mines which provided Teck the right to earn a 50% interest in the Guadelupe de los Reyes Project, Sinaloa. (GCN #248 24Dec92).

San Nicolas VMS Deposit, Zacatecas: 

Current status as of March, 2002 is that a positive bankable feasibility study has been tabled. This study was based around a plant to treat 15,500 tonnes of ore per day over a 12 year mine life that would produce 2.1 billion pounds of Zn, 1.4 billion pounds of Cu, 171,000 oz Au and 18 million oz of Ag. Sensitivity analysis shows metal prices and freight costs to be critical factors in the project's economics. Weak Zn prices are the Achilles heel at the moment.

Work through 1998 on the San Nicolas discovery had delineated a measured open pit resource of 74 million tonnes grading 1.4% Cu, 2.1% Zn with an overall strip ratio of 4.3:1 to a depth of 420 m. High-grade Cu mineralization extends beneath the planned pit. Now at the pre-feasibility stage with final feasibility expected to be completed in the year 2001. 

Initially started out as exploration JV with Western Copper Holdings on oxide Cu and polymetallic massive sulfide near Zacatecas. As of 10/28/98 the preliminary reserve estimate for an open-pit stood at 72,000,000 tonnes averaging 1.35% Cu, 2.27% Zn, 0.53 gpt Au and 30 gpt Ag to a depth of 400 m with a waste to ore ratio of 8:1 (MEG Luncheon Talk Abstract)

Present JV is Teck/Western 55/45 participating interests (Minera Tama S.A. de C.V.) on a 22,000 ha land package over El Salvador and La Virgen concessions. Total package is around 225 sq km. Additional ground was optioned from Luismin and acquired by Teck on 6Mar00 after Minera Tama's right of first refusal. This new acquisition represents another 25% interest in the deposit itself. Overall ownership and options between Teck's indirectly owned company that owns the San Nicolas deposit (Quiriego Compania Minera  S.A. de C.V.) and Western Copper are complex, but to make a long story short - if Teck exercised all of its options it could increase it's direct participating ownership in the deposit to a total of 81.5%, the remainder being Western Copper.

 EARLY HISTORY: Near-surface oxide zone believed to be 10m thick. Air-track drilling deliniated the oxide horizon over 350m by 600m and from 3 to 30m thick and grades around 1.0-1.5% Cu. First discovered massive sulfide horizon is 75m beneath oxide zone and is 5.1 ft (<2m) thick) at grades of 16.57% Zn, 2.07% Cu, 1.53% Pb, 3.68 grams Au and 213 grams Ag. This skinny horizon was cut by 5 or 6 holes out of the first 11 drilled. Hole SAL-97-01 (now renamed SAL-12) hit a 13.3 m massive section between 73.4 and 86.7m beneath the surface. This zone varies from 1 to 13m thick over a 150m wide by 400m long trend. and this upper horizon is not the same as the bigger, deeper one at San Nicolas.

A Dighem airborne survey was completed in 1Q97. Discovery hole SAL-25 on what is now known as the San Nicolas Massive Sulfide Orebody intersected 176 m of massive sulfides in November, 1997. The deposit is buried 200m beneath Tertiary volcanics and conglomerates and was discovered using geophysical survey techniques and some excellent interprative work by Joe Ruetz, Roger Scammel, Jim Janzen, Gillian Kearvell and Antonio Montante. By the end of 1997 six holes had intersected massive sulfides ranging from 59 to 260m in thickness. (NOTE: A lot of news came out on San Nicolas in 1998 and it is best to follow it on Western Copper's website).

Nukay Project, Guerrero: 70/30 JV Minera Nutek with privately-owned Miranda Mining located 150 km SW of Mexico City and NW of Chilpancingo. Small producer currently at 20,000 opy. In 1995 over 20,000 m were drilled outlining potential for both open-pit and underground mining. 1996 program concentrating on infill drilling. A drill hole late in 1994 intercepted 1.6 grams over 200m in skarn-altered zone adjacent to intrusive. Grade and tonnage numbers are hard to come by but in Aug. 1995 NMN reported 4.4 M tonnes at 4.47 grams Au or over 656,000 oz of contained Au in the Nukay, Aguita and Subita skarn zones and an inferred additional 800,000 in the Dona Marta Area. Los Filos zone showed drilled out resource of 28.4 M tonnes averaging 1.64 gpt Au. A 1.6 million ounce open pittable resource has been defined at Nukay and preliminary metallurgical testing looks good for heap-leach processing. Preliminary feasibility studies were planned for 1st half of 1998. Low gold prices has slowed this project down a bit in 1999, but it is still very much on track.

Terratech Encironmental Corporation 

Operates in Mexico as Minera Terra Gaia S.A. de C.V. and now also has 100% control of Minera Curator S.A. de C.V.

A Special resolution of International Curator Resources Ltd. shareholders voted to transfer all the issued and outstanding shares of Mintec International Corporation and its' wholly owned Mexican subsidiary Minera Curator S.A. de C.V., owner of the Boleo Project to Terratech pursuant to the terms of settlement Agreement dated February 15, 2001.

Boleo Cu-Co-Zn Project, Baja California has reported global resource of 537 million tonnes grading 0.73% Cu and 0.054% Co. International Curator excercised all of its options and now controls 100% of this project wich includes 10 seperate mining concessions. Final payment was made in December, 1997. Mineable reserves of 70 million tonnes at 1.29% Cu and 0.089% Co with 0.062% Zn. LPF (leach-precipitation-floatation) pilot plant testwork by Hazen Research completed. The LPF concentrate is needed to feed continuous SX/EW plant. Through this process recoveries are 97% for Cu, Co 98% and Zn 93%. Up until 3Q97 Zn did not enter into the economics. Private placement completed in Jan. 1999 to fund ongoing work.

High-grade hit w/15 wide spaced holes averaging 2.20% Cu and 0.093%Co over 2.62 meters. Curator is working diligently towards completion of a feasibility study. Around a 20 square km area in the NW portion of the claims is the focus of this initial study which includes data from 773 DDH. Preliminary evaluation of a leach-precipitation-float (LPF) processing has been very positive. Rigorous check and re-assaying upgraded Co values by 15% and Cu by 3%. The feasibility work undertaken by Flour Daniel Wright and includes metallurgical testing by Hazen Labs and Lakefield Research; ore reserve calculations by Mintec; mine planning by Norwest Mine Services; geotechnical studies by Golder and Assoc; tailings studies by Knight and Piesold; hydrological work by Servicios Geologicos and environmental work by Corp. Ambiental de Mexico. International Curator estimates 15-22 year mine-life for Boleo at a capital cost investment of around $480 million to get it going. Bankable feasibility expected by March, 1998. Discussions with potential pre-qualified partners ongoing as several have visited data room. Prefeasibility is complete and economic for an Op mine with Cu, Co and Zn produced by LPF-Roast_Leach-SX/EW processing.
