Geophysical Report Confirming Mineralization Depth Extends To 500 Meters At Mexican Hat
VANCOUVER, BC - GMV Minerals Inc. has received an Interpretive Report summarizing several geophysical surveys completed at the Mexican Hat Gold project in southeast Arizona.
Zonge International Inc., a provider of geophysical field services, consulting and instrument development to geoscientists and geotechnical engineers worldwide, has completed extensive geophysical surveys for GMV Minerals including; (a) Audio-Frequency Magnetotellurics, (b) Gravity, and (c) Ground Magnetics. The primary objective of the surveys was to collect data that could be used to create electrical resistivity models that would guide mineral prospecting efforts and to identify drill targets in the area.
Mexican Hat mineralization correlates well with a magnetic low and resistivity low (weak conductors) and has traced mineralization to depths of 500 meters for resistivity anomalies. Currently, GMV has drill data to a depth of only 200 meters utilized within its current NI 43-101 report.
Overburden cover is less than (<) 50 meters deep across the survey area. This has been confirmed by past drilling. Additional new target zones have been identified demonstrating low resistivity occurrences 100 meters south of Hernandez Hill (associated with an isolated magnetic low) and over the northern 800 meters to 1,000 meters on all three test lines, with evidence of low magnetic response over portions of this anomaly.
Ian Klassen, President of the Company says "Zonge International's interpretation demonstrates that the known mineralized domains are characterized by both magnetic lows and more conductive zones, as expected for mineralization that is associated with hematite and carbonate in fractured rocks. We are extremely pleased that this mineralization has been traced to depths of at least 500 meters below surface. Other similar geophysical responses can be found in broad areas to the north that have no bedrock exposure and have not yet been drilled. These responses represent exploration targets that require additional follow-up work. Confirmation of shallow cover over the bedrock was expected and supports GMV's low cost exploration and conceptual open pit extraction model. Additional geophysical surveys are being planned to extend the survey over an even broader area."
GMV has completed its first diamond drillhole MHC 17-6, a 75m step-out to the west of the nearest drillhole completed on the Mexican Hat Deposit. It has intersected six hematite and carbonate-altered brecciated and fractured volcanic rocks, some with limonite alteration, before ending in fine-grained siliceous siltstones presumed to be Bisbee Group sediments at a depth of 217m. Three of the zones intersected correlate with the N, AN, and H2 Zones and three of the zones occur to the north of the N Zone and appear to correlate with trench exposures and two historic drillholes completed by previous operators. MHC 17-7 has been collared from the same location but is being drilled 30 degrees to the east of MHC 17-6 together with the third hole MHC 17-8, which will provide information to enable solids to be constructed for resource purposes.
