UPDATE ON GOLD TARGETS - EXPLORATION AREA II, LOS ZORROS, CHILE |
||
A gravity geophysical survey, detailed geologic mapping, and re-logging of certain Phase I drill core has helped to better understand and outline gold targets in Exploration Area II of the Los Zorros property. The nature and geochemistry of these targets were previously reported in News Release No. 1-05 dated January 21, 2005. Three of these targets (see Figure 1), Target A (Milagro Mine), Target C (Milagro Pampa) and Target D (La Florida), will be included for drilling as part of the proposed Phase II exploration program to follow-up numerous gold, copper-gold and silver targets on the Los Zorros property. Target B is not currently being considered for follow up, but may be pursued at a later date depending upon further results in the area. The three targets are summarized as follows: Target A (Milagro Mine) (see Figure 2) is an area where Phase I drilling intersected gold-mineralized mantos and underlying thick hydrothermal breccia that may be part of an important gold zone. The mantos zone was intersected between drilling depths of 27.0 to 31.7 meters. The gold content ranges from 1.240 grams/metric tonne to 4.140g/mt and averages 2.579 g/mt gold with a silver average credit of 15.9 g/mt over a true width of 4.4 meters (previously reported in News Release No. 1-05). Of importance, the gold-mineralized mantos occurs within a very wide halo of strongly anomalous gold values. The gold mineralization (mantos) of the Milagro Mine area is fortuitously located in an uplifted (horst) block and occurs just below the floor of a gabbro body. The gravity expression of the dense gabbro body masks the presence of the low-gravity character of the underlying altered rocks which host the gold mineralization. The surface extent and indications of gold mineralization in the horst block defines a target size of 300 to 400 meters across by 800 meters down dip (easterly). The mantos interval and better mineralized upper part of the underlying breccia are together approximately 50-meters thick. If better grade gold-mineralized intervals can be found by drilling, the target dimensions are permissive for 25 million to 35 million metric tons within the uplifted (horst) block. The spatial extent of the gold-mantos and underlying breccia zone in down-dropped blocks to the north and south flanking the horst block of the target area are unknown at this stage, and may be the focus of later explorations efforts. Two or three core holes are planned to drill the projected down-dip continuation of the gold mineralized mantos interval and underlying breccia to the east. Target C (Milagro Pampa) (see Figure 3) is a stockwork-veined, sericite-clay-quartz-altered/pyritized gabbro sill with strongly anomalous copper-gold-silver and mercury content which is concealed beneath pampa cover and was discovered during Phase I drilling in hole ML-04-03 (previously reported in News Release No. 1-05). The strong alteration, anhydrite and quartz-pyrite stockwork veining, and highly anomalous copper content intersected suggests that Milagro Pampa is near the center of the intrusive porphyry source of the mineralizing system. The typical gravity high expression of the gabbro over the region is considerabley diminished by the alteration/mineralization effects at Milagro Pampa. The hole did not quite reach and penetrate through the floor of an altered and mineralized gabbro body, but garnet skarn xenolith blocks comprising the last twenty meters suggest that the hole was stopped near the floor contact with underlying rock. The strong alteration, pyritization and variable anomalous copper over the entire length of the hole may comprise the outer halo to substantial gold-copper mineralization hosted in altered porphyry and layered skarnoid sedimentary and volcaniclastic rocks that likely underlie the gabbro body. In light of the gold mineralization being concentrated just below the floor of the gabbro unit at the Milagro Mine (Target A), exploration results make a strong case to test for copper-gold mineralization underlying the gabbro in the Milagro Pampa area. The fault-bounded prospective area of Milagro Pampa measures 1000 meters by 500 meters with the top of the target becoming progressively deeper in a down-dip direction to the east (ranging approximately 400 to 500 meters vertical depth). One to two core drill holes are proposed to test this target during Phase II. Target D (La Florida) (see Figure 4) is an area where Phase I trenching and sampling exposed silicified and clay-altered quartz-eye porphyritic intrusion with significantly anomalous gold content including a 138-meter interval averaging 0.405 g/mt (previously reported in News Release No. 1-05). The gold mineralized/altered intrusion intrudes up through a little-altered, thick diorite sill and coincides with a well-defined gravity low. The surface outcropping, oval-shaped area of gold mineralized quartz-eye porphyritic dacite intrusion encompasses approximately 200 meters wide by 400 meters long. Similar altered/mineralized porphyritic intrusion outcrops/daylights elsewhere in the vicinity, indicating the target extends over a much greater distance beneath the surrounding area. One to two core drill holes are proposed to test this target during Phase II. The Phase II drilling program being planned for Los Zorros is expected to entail approximately 5,000 meters of core drilling, bulldozer trenching, geologic mapping, rock-chip and trench sampling and assaying (see News Release No. 8-05, Sept. 9th, 2005). The complete program is estimated to cost CDN $1,500,000. Funding for this program will be sought through private placement financings, and drilling will begin once remaining targets are fully defined/prepared and funding is in place. Bulldozer trenching has been completed in Exploration Area IV, and geologic mapping, sampling and assaying are ongoing in order to define targets for Phase II drilling. Target descriptions will be announced once the data is compiled and evaluated.
