GLENGARRY BASE METALS PROJECT UPDATE
Key points
• CSIRO targeting study at Glengarry project area complete
• Priority base metal and uranium exploration targets identified
• Exploration programs at project to commence in near future Emergent Resources (Emergent, the Company) (ASX: EMG) is pleased to provide the following update on activity at its Glengarry base metals project near Wiluna in Western Australia. The Company has completed a detailed mineral mapping and alteration study of its Glengarry base metals assets. The study was a collaborative study between the CSIRO’s Minerals and Environmental Sensing Group and the Company, and outlined several surface base metal and uranium targets for early exploration. The study also incorporated interpretation of Emergent’s Hyperspectral infrared reflectance spectral data, which was acquired shortly after the Company’s ASX listing in August 2008. The CSIRO study The CSIRO were tasked with producing and interpreting a series of mineral maps (which highlight the mineralised fluid migration pathways from source rocks to depositional sites). The mineral maps were subsequently overlain over lithostructural framework (the structures which promote and/or arrest fluid migration) established by Emergent, which was used to prioritize targets. The resulting identified targets include redox and pH-driven uranium mineralisation and several spot occurrences of alunite, which is possibly associated with base metal mineralisation. Emergent now plans to commence field exploration activities in support of the study results in the near future.
Airborne hyperspectral data background The Company acquired airborne hyperspectral data covering its 2500 km2 of tenure in the Glengarry region. The project area is highly prospective for base metal mineralisation, as well as calcrete and palaeochannel-hosted uranium, and gold mineralisation. It is also largely covered by a veneer of recent sediments making surface exploration difficult.
Hyperspectral infrared reflectance spectra are used to identify abundances and compositional differences of mineral groups and single mineral phases on the earth’s surface. Many of these differences result from the interaction between migrating mineralised fluids and the rocks that host them. It stands to reason that where mineralized fluid pool longest, the greater the interactions between the wall rock and the fluid, the greater the level of alteration in the rock. Mineral deposits are often found in such settings. The advantages of hyperspectral techniques over conventional exploration methods include: (1) the fast and cost efficient acquisition of surface and sub-surface mineralogy (via drilling), and (2) objective mineral mapping compared to subjective field mapping and drill core logging by various geologists. Furthermore the surveys identify surface components not readily discernable to the naked eye, and provide complete coverage of project areas within the survey footprint. In thinly covered environments in apparently uniform terrain, hyperspectral data is able to discern areas of outcropping bedrock. Similarly key alteration minerals, such as alunite, which is typically associated with high sulphidation mineralised systems, can be identified before the commencement of on-the-ground field activities.
