Apogee Drill Results Confirm the Presence of High Grade Veins and Broad Zones of Mineralization at Candelaria, Santa Isabel
TORONTO, Ontario April 5, 2005 Apogee Minerals Ltd. (TSX Venture Exchange: APE) has received all remaining analytical results from its Phase 1 drilling program at the Candelaria at Santa Isabel project in the Potosi district of southwestern Bolivia (see Press Release dated December 3, 2004). The preliminary Phase 1 exploration program was designed to test one vein set (the Consuelito vein), a small portion (300 x 150 metres) of the larger vein system (3000 metres x 2500 metres) at Candelaria, Santa Isabel and to confirm the potential for both high grade veins and possible bulk-mineable mineralization consisting of veins and veinlets.
Apogee Vice-President Exploration Robert Campbell commented: “These new drill results are very significant and confirm the presences of high-grade Silver-Zinc-Lead veins within a broader zone of Silver-Zinc-Lead mineralization. The results to date from Consuelito reflect data from only one small vein set of many across an area of 7.5 square kilometres. As more data is compiled and we prepare to begin a Phase 2 program at Candelaria with an improving perspective on the system, we will be sampling and drilling across a broader set of important veins”.
The results from the preliminary 3-hole drill program confirm the possibilities for both high grade veins and potential bulk-mineable mineralization consisting of veins and veinlets. Assay results from drill Hole #1 (SI-04-01) included several significant high grade Silver-Zinc-Indium veins, including 15 metres of 252.9 g/t Silver, 13.11% Zinc, 1.36% Lead and 230.2 g/t Indium (see Press Release dated February 10, 2005). Hole # 2 (SI-04-03) intersected 109 metres (136-245 metre) 1.11% Zn and 9.98 g Ag/t including 4 metres (136-140 metre) 3.23% Zn and 19.14 g Ag/t and 3 metres (175-178 metre) 4.69% Zn and 19.10 g Ag/t. Hole # 3(SI-05-04) intersected 4 metres (39-43 metre) 2.19% Zn and 59.50 g Ag/t.
Holes # 2 and #3 represent more of the broader zone of mineralization which is common in these types of deposits. The Bolivian Altiplano and Eastern Cordillera hosts an important metallogenic event. Major hydrothermal ore deposits of gold, silver, tin, lead, zinc, bismuth and antimony are related to near-surface stocks and subvolcanic eruptive centers. The mineralization occurs in veins, fracture swarms, dissemination and breccias. The deposits are telescoped with early high temperature phases and have some affinities with the epithermal low-sulfidation type model.
“We are very pleased with the progress of our Phase I program at Candelaria at Santa Isabel” stated Apogee President and CEO John Carlesso. “The results we have received are confirming our model of the area and we are actively planning Phase II to expand and quantify the known areas of mineralization”.
The significant points of interest at Candelaria, Santa Isabel are:
-
The property is situated within one of the key metals (Ag, Zn, Pb, Sn, & Sb) mining regions in the world, remaining one of the most important for both current production and future growth.
- The significant size of the vein system and related stockworks covers an area 3.0 km x 2.5 km (7.5 square kilometres).
-
Numerous veins and veinlets are present throughout, commonly with swarms of closely spaced, splaying smaller veins in sheeted zones. Veins vary in width from microveinlets to 10’s of metres, and commonly are 2 to 4 metres wide. The ore shoots in veins are commonly 200-300 m along strike and dip but the veins may extend to more than 1000 metres in depth and strike length.
-
The vein system displays impressive vertical and horizontal continuity with marked metal zoning. Deeper veins of mainly massive sulphide minerals contain Sn, Ag, Zn and Pb; the shallower veins with quartz-barite and chalcedony-barite carry Ag and rarely Au. Metal zoning from depth to surface and from centres outward shows: Sn + Cu + Zn, Pb + Zn, Pb + Ag and Ag ± Au; commonly there is considerable ‘telescoping’ of zones.
The Candelaria at Santa Isabel Project is located in southwestern Bolivia, approximately 587 km south southeast of La Paz, within the San Antonio de Lipez District, Potosi Department, near the border with Argentina. The property is comprised of one 200 ha block and Apogee Minerals has reached an agreement with the owner to acquire up to a 95% interest in the property through exploration expenditures and cash and share payments over a four year period (see Press Release dated Oct. 6, 2004).
Apogee’s Phase 1 Exploration program at Candelaria at Santa Isabel consisted of detailed geological mapping, re-sampling existing mineralized drill core and anomalous trenching to verify previous results, new surface sampling and 3 holes totalling 1,012 metres of diamond drilling.
Apogee’s next phase of work will focus on completing the compilation on the rest of the veins, underground and surface sampling, mapping, and preparing the property for an aggressive drill program.
