Apogee Intersects High Grade Mineralization at Pulacayo Silver-Zinc Project Drilling Confirms Apex Silver Historical Drill Intersections
TORONTO, ON June 22, 2006 Apogee Minerals Ltd. (TSX Venture Exchange: APE) has intersected broad zones of high grade mineralization within the Tajo Vein system on its surface drilling program at the Pulacayo Silver-Zinc-Lead project. These intersections, which follow recent high-grade Silver-Zinc results from the nearby Paca Open Pit target, continue to confirm historical drill results obtained by Joint Venture partner Apex Silver Mines Limited (AMEX:SIL) in 2002.
Apogee Vice President, Exploration Doug Currie stated: “These results, which confirm historical drill results, are very exciting. We are now planning for a more comprehensive infill drill program to confirm the potential of defining an open pit target on the upper, oxidized portion of the Tajo Vein system.”
Results of five surface holes drilled at Pulacayo to twin and infill between drillholes completed by Apex include the following significant intersections (Table 1):
To view Table 1 Significant Drill Results Pulacayo Project PUD-028 to PUD-032: www.prophecycoal.com/apogee/pdf/jun22_2006_table.pdf
- PUD-028: 13.0m @ 153.31g/t Ag, 1.74% Pb, 1.54% Zn
27.0m @ 53.24g/t Ag, 0.38% Pb, 1.42% Zn - PUD-029: 12.0m @ 18.28g/t Ag, 0.69% Pb, 2.01% Zn
13.0m @ 26.92g/t Ag, 1.05% Pb, 1.98% Zn - PUD-030: 4.0m @ 66.54g/t Ag, 1.55% Pb, 4.22% Zn
- PUD-031: 40.0m @ 39.10g/t Ag, 1.40% Pb, 1.54% Zn
23.0m @ 27.09g/t Ag, 0.52% Pb, 2.53% Zn - PUD-032 : 42.0m @ 33.98g/t Ag, 0.48% Pb, 2.88% Zn
Within broader zones of mineralization, there are also several very high grade silver and zinc rich intersections, for example:
- PUD-028: 2.0m @ 386g/t Ag, 3.90% Pb, 3.08% Zn (150.0-152.0m)
2.0m @ 560g/t Ag, 5.88% Pb, 1.82% Zn (159.0-161.0m)
1.0m @ 569g/t Ag, 1.85% Pb, 4.36% Zn (212.0-213.0m)
1.0m @ 428g/t Ag, 0.96% Pb, 3.15% Zn (215.0-216.0m) - PUD-032 10.0m @ 114.5g/t Ag, 1.07% Pb, 7.42% Zn (204.0-214.0m)
These higher grade veins are typical of the high-grade Tajo Vein style mineralization that was historically mined from the 1890’s to the late 1950’s.
These results follow the significant high grade mineralization that was intersected in the first drillholes at the nearby Paca Silver-Lead-Zinc Open Pit Target in May (see Apogee Press Release May 1, 2006). Results included 32.0m averaging 308g/t silver, 0.76% lead and 0.42% zinc in PND-031 and 23.5m averaging 89.3g/t silver, 1.00% lead and 2.00% zinc in PND-032. Results of the remainder of the holes drilled at Paca should be available shortly.
Apogee has completed a total of 1056m of surface drilling (5 drillholes, PUD-028 – PUD032) and 766m of underground drilling (4 drillholes, PUDU-001 to PUDU-004) at Pulacayo. Results of the underground holes are pending.
Additionally, geological mapping and surface chip and channel sampling at Pulacayo has located several interesting altered and geochemically anomalous zones which require follow-up trenching and possibly drilling. The surface exposure of the Pacamayo Zone, adjacent to the Pulacayo Mine, which is currently being mined underground by cooperative miners (Apogee grab sample of miners’ “ore”: 3300g/t Silver, 5.88% Lead, 3.59% Zinc) is highly altered and follow-up drilling is planned.
Apogee President and CEO John Carlesso commented: “I am very pleased that our initial drill programs at both Pulacayo and Paca have confirmed historical results. These results have given us confidence in our ability to meet our 2006 exploration objectives. Our efforts will now be focused on follow-up and infill drilling to achieve the outlining of a NI 43-101 compliant mineral resource.”
Apogee is preparing to commence an extensive 30-35,000m drill campaign on all projects at the end of June.
The current program, which commenced in December upon signature of the formal agreement, has consisted of a comprehensive program of geological mapping, surface and underground sampling and diamond drilling to confirm historical work and results of historical exploration by Apex Silver (See Apogee Press Releases, September 12, 2005 and January 19, 2006). Drilling has been completed at both the Pulacayo and Paca prospects.
Silver-zinc-lead mineralization at Pulacayo is related to a high level epithermal system hosted in an east-west vein structure, the Tajo Vein, which cuts a series of Tertiary dacite to andesite porphyritic intrusive rocks and andesite flows which intrude Tertiary sandstones and conglomerates. The structure consists of a number of veins, veinlets and stockwork. The structure has been traced along strike for 2500 metres and to a vertical depth of 1000 metres and remains open. The width of the structure varies from 0.50 metre to 50 metres. Mineralization consists of silica, opal, barite, pyrite, ruby silver, argentite, galena and sphalerite.
The recent drill program was designed to confirm historical drill results and to verify earlier interpretations. Several holes were “identical twins” of historical holes (eg PUD-029 vs PUD- 022; PUD-028 vs PUD-023 and -024); other holes were designed to intersect the interpreted mineralized lodes between historical drillholes (eg PUD-028 vs PUD-024 & PUD-020) (Figures 1, 2).
Results, shown in Table 1, indicate that Apogee’s intersections duplicate prior intersections where holes are close together and substantiate previous intersection grades where Apogee’s drillholes cut interpreted mineralized zones between historical holes.
History of Pulacayo-Paca Silver Mines
The Pulacayo-Paca project is located 460 km south of La Paz in the historic Potosi Department of Southwestern Bolivia, near the city of Uyuni in the middle of the San Cristobal-Potosi Silver Belt, a wide, well-mineralized string of silver deposits that extends from the southwest to the northeast and includes the three largest silver deposits in Bolivian history (Potosi, San Cristobal, and Pulacayo).
Discovered in 1883, the Pulacayo Silver Mine is 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. Today the project is located 45 km by gravel road from the city of Uyuni which is connected by highway and railway to the sea port Antofagasta. The site contains all necessary services; power, water and an experienced labour force from the surrounding village of Pulacayo.
In 2002, exploration work by Apex Silver discovered several additional zones of silver-zinc-lead mineralization within the vein system at the Pulacayo Mine that are both broad and high-grade. Apogee, operator of the Joint Venture, has the right to earn up to 60% interest in the Project. Phase 1 of the Earn-In Period requires Apogee to complete an initial expenditure of US$250,000 within the first six months of commencement of the Joint Venture (see Press Release September 12, 2005).
