The Neves-Corvo volcanic-hosted massive sulfide deposit is one of the largest (>300 Mt) and richest known deposits Iberian pyrite belt. unique because its extremely high Cu Sn grades (45 Mt at 6% plus 4.5 12% 2.2% Sn). More than 300,000 metric tons (t) tin metal contained in several types mineralization that grade from 500 ppm to 60 percent Sn. consists five orebodies, including Corvo, focus present study. volcanic, volcaniclastic, sedimentary lithofacies directly host consist a rhyolitic...
ABSTRACT High concentrations of indium (In) and selenium (Se) have been reported in the Neves-Corvo volcanic-hosted massive sulfide deposit, Portugal. The distribution these ore metals deposit is complex as a result combined effects early ore-forming processes late tectonometamorphic remobilization. In Se contents are higher Cu-rich types, lower Zn-rich types. At scale, both correlate positively with Cu, whereas their correlations Zn close to zero. This argues for genetic connection between...
To evaluate and upscale the feasibility of using exploration tunnels in an operating mine for active-source seismic imaging, a experiment was conducted at Neves-Corvo mine, southern Portugal. Four profiles were deployed drifts approximately 650 m beneath ground surface, above world-class Lombador volcanogenic massive sulfide deposit. In addition to tunnel profiles, two perpendicular surface tunnels. The survey possible due newly developed prototype global positioning system (GPS) time...
Abstract The recently discovered massive and stockwork sulphide mineralization of Semblana-Rosa Magra Monte Branco, situated ESE the Neves–Corvo volcanogenic (VMS) deposit in Iberian Pyrite Belt (IPB) is presented. Geological setting tectonic model discussed based on proxies such as palynostratigraphy U–Pb zircon geochronology. found within IPB Volcano-Sedimentary Complex (VSC) Lower sequence, which includes felsic volcanic rocks (rhyolites) with ages zircons 359.6 ± 1.6 Ma, black shales...
ABSTRACT Seismic methods are becoming an established choice for deep mineral exploration after being extensively tested and employed the past two decades. To investigate whether early European mineral‐exploration datasets had potential seismic imaging that was overlooked, we recovered a low‐fold legacy dataset from Neves–Corvo mine site in Iberian Pyrite Belt southern Portugal. This comprises six 4–6 km long profiles acquired 1996 targeting. Using today's industry‐scale processing...
Seismic methods are an affordable and effective way of studying the subsurface for mineral exploration. With goal testing new technologies exploration in highly challenging mining areas, early 2019, innovative seismic survey was conducted at Neves-Corvo mine, south Portugal. We have focused on data results from surface array data, whereas other work deals with underground data. The consisted two perpendicular 2D profiles positioned above known world-class tier-1 Lombador deposit....
Summary Volcanogenic-hosted massive sulphide (VMS) deposits show a strong seismic contrast (mainly due to their density) against almost all lithological host rocks therefore justifying direct targeting using methods ( Salisbury et al., 2000 ; Malehmir 2012 and references therein; 2013 ) when there is adequate signal-to-noise (S/N) ratio suitable geometry. While are earlier published accounts illustrating the use of for deep-seated VMS elsewhere Matthew, 2002 Bellefleur, 2009 ), number...
<p>Mineral exploration industry needs to push its technological advancement towards finding the so-called critical raw materials. These materials are fundamental for our green technologies and help accelerate energy transition decarbonisation. While in-mine near-mine will be more convenient in short term, providing fresh mines greenfield or brownfield areas must not forgotten longer term. As chase mineral deposits becomes deeper, seismic methods play a greater role exploring at...
Summary Seismic methods are an affordable and effective way of studying the subsurface for mineral exploration, particularly when target depths beyond what other geophysical can resolve (e.g., > 500 m). With goal testing new technologies exploration in highly challenging mining areas, a seismic survey was conducted at Neves-Corvo mine, south Portugal. The data acquired consisted two perpendicular 2D surface profiles positioned above known Lombador deposit. Due to active operations, show...
