GMV Minerals Inc. Discovers 8 New Geophysical Target Zones in Aurora Region, Guyana
|VANCOUVER, BC, October 3, 2011 - GMV Minerals Inc. (the "Company" or "GMV") (TSX V: GMV) is pleased to announce that it has received further detailed airborne magnetic and gamma-ray spectrometry survey data. The new data covers GMV's Aurora claims in Guyana. |
The airborne survey was comprised of 5,100 line-kilometres of magnetics and gamma-ray spectrometry. Enhancement filters applied to the magnetics have highlighted a number of dominant structural orientations and trends. Definite 'breaks' in the predominate WNW fabric are shown by the magnetics and identified as target areas of interest. These cross-trends provide potential for significant fracturing and mobilization of mineralized fluids such as gold.
Eight target zones of structural complexity are identified from the magnetic analysis. These prospective areas are based on inferred structural complexity being immediately adjacent to and within regions of major shear zones (magnetic discontinuity). Gold mineralization is known to commonly occur near major crustal breaks manifesting as large-scale shear zones, which act as conduits for mineralizing fluids. Mineralization therefore may occur in regions of structural complexity adjacent to the shear zones.
GMV's Aurora block lies directly south of Guyana Goldfields Inc.'s (TSX-V: GUY) property and is situated as the only major landholding between Guyana Goldfields' Aurora (6.9m ounces gold) deposit and Sandspring's Toroparu (8.4m ounces gold) deposit. Both of these deposits are in similar geology to that found on the GMV claims. The Aurora block and regional area presently are being worked for alluvial gold and have numerous historic workings in the area. Local access roads are presently being constructed as well the main roads to both deposits are being improved.
Anomalous potassium concentrations are mapped by the gamma-ray spectrometry as 'ringing' a magnetically-positive and anomalous Trans-Amazonian tectno-thermal granitoid inferred to occur in the northern half of the study area. These high potassium readings occur within otherwise potassium-poor rocks along or adjacent to inferred (magnetics) fault/shear zones and may therefore indicate anomalous sericite alteration. A significant correlation of low eTh/K ratio occurs in the northeast part of the survey block, in conjunction to the strongest zone of structural complexity interpreted from the magnetics. As thorium enrichment generally does not accompany potassium during hydrothermal alteration processes, eTh/K ratios often provide excellent distinction between potassium associated with alteration and anomalies related to normal lithological variations.
Airborne gamma-ray spectrometry surveys can be of direct assistance to exploration either because one or more of the radioelements is an associated trace constituent or because the mineralizing process has changed the radioelement ratios in the surrounding environment. Work completed to date on GMV ground and correlations to known mineral occurrences elsewhere in northern Guyana suggests that this ancillary data is providing key information to the current exploration programmes.
Douglas Perkins, GMV's VP Exploration remarked, "This is truly one of the most exciting areas to test in GMV's 1000 sq. mile land package. This new information has confirmed that we have the right ground not only from the proximity to significant defined gold deposits with similar geology but also by the anomalies indicated by the airborne survey and the presence of alluvial gold in the area."
A program of geological prospecting, sampling and ground geophysics consisting of detailed magnetics and 3D induced polarization / resistivity is planned to further delineate the conductive zones and possibly identify disseminated sulphides which in turn could indicate anomalous gold mineralization.
