Archangel Project: Multiple Porphyry Copper-Gold Targets
The Kay Tanda epithermal gold-silver prospect occurs on the Archangel Project, a granted Mineral Production Sharing Agreement.
Geology and Mineralization: Geology consists of strongly altered volcanics intruded by andesitic and dacitic intrusives, and overlain by younger cover volcanics to the northwest. A cluster of gold-silver and porphyry copper-gold prospects has been outlined along a strong northeast structural trend of at least six kilometers, which is open to the northeast.
Extensive phyllic, SCC (sericite-clay-chlorite) alteration, characteristic of porphyry copper-gold-related mineralization, along with abundant copper showings, occur along the six kilometer trend. Superimposed on this at higher elevations are areas of advanced argillic and argillic alteration which are interpreted as being "upflow" zones and which may indicate proximity to porphyry centers below. Near-surface zones of low-sulphidation epithermal gold-silver mineralization, including Kay Tanda, have been telescoped into the advanced argillic alteration and are interpreted to reflect especially fertile and metalliferous porphyry systems below.
The main features are shown on the Archangel Compilation and in the 3-Dimensional Model. These illustrate the extent of the chargeability anomaly (indicating metal sulphides), plus epithermal gold silver zones as mapped at surface, and zones of advanced argillic alteration. The latter can be especially important guides to porphyry copper-gold systems nearby.
A National Instrument 43-101 resource estimate has been commissioned for the Kay Tanda prospect and is expected in the third quarter of 2007. This will be followed by a scoping study, the object of which is to begin evaluating the feasibility of taking the Kay Tanda prospect to production. All work on the Project is carried out under the supervision of Tony Climie, P. Geol., President of Mindoro and a "qualified person" as defined by National Instrument 43-101.
Kay Tanda is part of a six-kilometer trend of strong geophysical anomalies, gold and copper showings and hydrothermal alteration, with high potential for additional discoveries of epithermal gold silver and related porphyry copper-gold deposits at depth. (more...)
Ahit-Balibago is an 800 meter by 600 meter, high-chargeability anomaly with a coincident resistivity anomaly. Ahit Hill exhibits intense argillic and advanced argillic alteration, probably telescoped into the top of a porphyry system. PIMA clay analyses revealed prominent high-temperature potassic white mica (high-temperature illite). Extensive and strong copper-in-soil anomalies are associated with the alteration.
In 2006, two reconnaissance diamond drill holes, 500 meters apart, were drilled to test the strong chargeability anomaly coincident with copper-oxide showings and quartz veining. The holes intersected dacite porphyry, diorite, and quartz diorite stocks intruding andesite and dacite volcanics. Porphyry-related alteration was intersected and varies from SCC (sericite-chlorite-clay) to phyllic (quartz-pyrite-clay) overprinting propylitic alteration. Weak to moderate sulphides were intersected, including pyrite and minor chalcopyrite, covellite and bornite associated with galena and sphalerite. The holes bottomed at 500 meters depth in the anhydrite-gypsum zone of the porphyry system, which is normally adjacent to the potassic mineralized core. The information will be used to target later drilling with a larger drill rig to vector into the mineralized porphyry center.
The Marita prospect is located northeast of Kay Tanda, and is a one kilometer by 700 meter high-chargeability zone with a coincident high-resistivity anomaly. The area is underlain by volcanics intruded by dioritic to dacitic intrusives, capped and masked by young volcanic cover to the northwest. Alteration is phyllic, overprinted by intense argillic alteration. Detailed mapping, including analysis of fracture pattern, and trenching activities revealed strongly oxidized quartz-sulphide stockworks, in places with associated copper mineralization. A highly silicified and stockworked boulder contains disseminated chalcopyrite and assayed 9.92 g/t gold (surface-enriched).
Bootin is located about 1.5 kilometers north of Marita and is associated with high-chargeability and high-resistivity anomalies. The area is largely covered by young, cover volcanics with windows of phyllic-altered andesite, andesite porphyry and diorite. A hydrothermal breccia pipe with a matrix of fine pyrite and clay occurs on the northwest side of the prospect. Zones of argillic to advanced argillic alteration have been mapped and localized copper showings found. A grab sample from a north-northeast trending gougy fault assayed 27.61 g/t gold. Drilling is planned for 2008.
