Apogee Completes Resource Definition Drilling and Identifies Expansion Potential of Silver-Zinc Mineralization at Paca Open Pit High Grade Intersection of 33m @ 312.91g Silver/T
TORONTO, ON February 1, 2007 Apogee Minerals Ltd. (TSX Venture Exchange: APE) has received additional results from the Phase II resource definition diamond drilling program at the Company’s Paca Silver-Zinc Open Pit Target that have confirmed the intersection of broad zones of silver, zinc and lead mineralization on the western side of target area. Drilling is complete and Micon International have commenced resource calculation and NI43-101 Technical Report.
A 40m wide silver-rich mineralized zone intersected in hole PND-084 commences 7m below surface, averages 81.28grams silver per tonne (g Ag/t), and contains a very high grade intersection of 22m @132.95g Ag/t, 1.91 % Pb and 1.37 % Zn (Tables 1, 3;Figure 1). Hole PND-084 is approximately 50m to the east of hole PND-069 which also had very significant shallow high grade silver values, including 17m @ 146.53 g Ag/t, 27m @ 127.67g Ag/t and 21m @ 81.57g Ag/t in the upper 89m of the hole (see Press Release dated November 7, 2006). Hole PND- 091, approximately 50m to the south of PND-084, intersected a 140m thick mineralized zone, also from surface.
High grade silver values were also intersected in holes PND-087, 089, 092 and 093 adjacent to the northern limit of the Paca intrusive; best results included 33.0m @312.91g Ag/t in PND-092, 19.0m @518.0g Ag/t in PND-093 and 18.0m @ 188.0g Ag/t in PND-096.
Apogee Vice President Exploration, Doug Currie, commented: “The near surface high grade silver zone identified in holes PND-069, 084 and 091 is very encouraging as we have now confirmed the potential for extension of the mineralized system both to the west and north. The thick, very high grade silver rich zones in holes PND-087, 089, 092 and 093 adjacent to the Paca andesite dome will significantly increase the potential silver resource.”
The Phase II Resource Definition Drill Program has now been completed and Micon International Limited of Toronto, Canada, have commenced the resource estimation and preparation of a NI43-101 Technical Report, both of which are expected by mid-February.
Significant results reported in this release are primarily for drillholes on the western extension of the potential resource area and adjacent to the contact with the Paca andesite intrusive dome. The results reported confirm that these zones are indeed mineralized with thick zones of encouraging zinc and lead mineralization greater than 1.5- 2.0% Pb+Zn which also contain higher grade silver intersections (Tables 1, 3; Figure 1).

Drilling to outline the extremities of the potential resource area with 100m x 100m spaced drilling and to infill previously identified areas of mineralization on a 50m x 50m drill spacing commenced in July and continued with two diamond drills until just prior to Christmas with two diamond drills on site. Results contained in this release relate to drillholes PND-073 – PND-106 ( 33 holes, 7471 m, excluding PND-101, in progress).
History of Pulacayo-Paca Silver Mines
The Pulacayo-Paca project is located in southwestern Bolivia near the city of Uyuni, 460km south of La Paz, Bolivia, in the historical San Cristobal-Potosi Silver Belt, a wide, well mineralized zone of significant historical silver producers, including the three largest silver deposits in Bolivian history (Potosi, San Cristobal, and Pulacayo).
Discovered in 1883, the Pulacayo Silver Mine was the second largest silver mine in Bolivia after Cerro Rico de Potosi and one of the most important in Latin America, having produced over 600 million ounces of silver, 180,000 tonnes of zinc, and 180,000 tonnes of lead from 1883 to 1959 (ref. Sergeomin – Bulletin No 30, 2002). Production has been mainly from the non-outcropping Tajo vein system which was exploited to a depth of 1000 meters and averaged 30 ounces per tonne of silver over a strike length of 2500 meters. Revenue from the mine funded the first railway line to Bolivia, which connected the mine to the port of Antofagasta, Chile in 1888. The project is located 20 km by gravel road from the city of Uyuni which is connected by highway and railway to the sea port of Antofagasta, Chile. The site contains all necessary services: power, water and an experienced labour force from the surrounding village of Pulacayo.
The Paca project is located approximately 5km north of the Pulacayo mine and town site. Only minimal historical mining has occurred at Paca. Previous interpretation of geological mapping and historical drilling by Apex Silver indicated that mineralization reported was predominantly “mantos-style†within a shallow, flat-lying sedimentary unit which overlies a sub-vertical brecciated “feeder†zone related to an andesite intrusive dome. Mineralization within the “mantos†is dominantly high grade silver, with weaker lead and zinc values; mineralization in the “feeder” zones generally has higher grade lead and zinc values than in the mantos, with narrow, moderate to high grade, silver values.
Apogee geologists now believe that the geology of the Paca mineralized zone is more complicated than originally interpreted, with potential for feeder-style mineralization being more widespread than originally thought and for additional zones of flat lying mantos-style mineralization at depth within the sedimentary unit.
Apogee entered into a joint venture agreement with Apex Silver late in 2005 which allows Apogee to earn a 60% interest in the property by spending US$1.0million on exploration, including US$250,000 during the first six months, and completing a Feasibility Study during a three year Earn-in Period; Apex Silver have an option to increase its interest to 60% by funding development to production (see Press Release dated September 15, 2005).
