VR Resources Limited has announced the successful completion of a detailed 3D-array DCIP geophysical survey at its Bonita porphyry copper-gold project located in Nevada. The survey specifically targeted the Copper Queen area, which is interpreted as an alteration lithocap, with the primary objective of mapping subsurface sulfide density and providing precise exploration vectors for future drilling initiatives.
Survey Execution and Technical Details
The geophysical survey was executed on time, on schedule, and within the allocated budget, covering a substantial grid block of approximately 1.5 by 3.5 kilometers. This extensive coverage includes the entire hilltop at Copper Queen and the surrounding lowlands, ensuring comprehensive data collection across the target area.
Utilizing state-of-the-art DIAS32 technology, the survey generated robust data sets, with the 3D resistivity model containing around 187,000 data points and the induced polarization model comprising approximately 135,500 data points. The depth penetration for the 3D modeling is estimated to reach about 400 meters, allowing for detailed subsurface analysis.
Strategic Planning and Collaboration
The survey was meticulously planned following extensive previous exploration work on the property, including reconnaissance-level drilling. The design was reviewed and finalized in collaboration with Dias Geophysical, a leading provider of geophysical services, during the recent AME Mineral Exploration Conference in Vancouver. This partnership ensured that the survey adhered to industry best practices and leveraged expert insights.
Dr. Michael Gunning, Chief Executive Officer of VR Resources, expressed enthusiasm about the project's progress, stating, "We are excited to advance our exploration at Bonita and pleased with the field execution by the DIAS team, which was completed on schedule and on budget."
Geological Context and Exploration Goals
The Copper Queen target is characterized by significant scale, dominated by secondary albite and hematite alteration, with copper veins present at the surface from historic workings at the 1936 mine. The survey is specifically designed to optimize the mapping of sulfide and alteration minerals at depth beneath the central part of the hill, where these veins emerge.
The primary goal of the DCIP survey is to provide a precise exploration vector for follow-up drilling, building on surface mapping and previous exploration surveys conducted by VR Resources. This includes data from the company's initial reconnaissance-style drilling at Copper Queen in 2017, which revealed porphyry-style copper-sulfide veining associated with anomalous copper-gold geochemistry.
Future Prospects and Data Analysis
The target at Bonita is a buried, alkaline porphyry stock or breccia body containing copper sulfide and gold, central to the alteration, vein, dyke, and breccia system mapped and sampled across the hilltop and lowlands. VR Resources aims to uncover further details from the new DCIP survey once data processing, inversions, and 3D models are finalized, paving the way for advanced mineral exploration and potential resource development in Nevada's mining sector.
