Durango Defines Geophysical Exploration Targets for Decouverte Property
Vancouver, BC December 6, 2017 – Durango Resources Inc. (TSX.V-DGO), (the “Company” or “Durango”) announces that further to the news of October 23, 2017, Durango has received a geophysical interpretation report by INRS (Institut national de la recherche scientifique) defining nine exploration target areas on its wholly-owned Découverte property in Quebec (the “Property”).
A 9.9-line kilometre geophysical survey was completed in November 2015 by INRS Centre Eau Terre et Environnement on the Property, in the James Bay Eyou Istchee Territory of north-central Quebec. The Property is located north of the Assinica Reservoir, 60 km southwest of Troilus and is neighboured by Osisko’s Assinica property to the west. The local geology is characterized by classic Archean greenstone belt bedrock covered by a thin veneer of glacial tills. Magnetometric, frequency domain EM and gravimetric surveys were carried out along three sections (lines 100, 200 and 300). The purpose of the surveys was to define conductors with coincident magnetic anomalies that may be related to gold and gold-rich VMS-style mineralization.
Results from the ground geophysical survey are as follows:
- Line 100 shows a strong magnetic and gradiometric anomaly that is associated with a conductor. Host rocks are wacke and conglomerate of the Broadback Group and a granodiorite.
- Line 200 has five conductors with coincident magnetic anomalies. Host rocks are finely bedded metasedimentary rocks of the Broadback Group and mafic metavolcanic rocks of the Assinica Group.
- Line 300 has two conductors with coincident magnetic low, host rocks are mafic metavolcanic rocks. A 2D Inversion model of the geophysical data measured along line 300 shows strong variability in the electrical resistivity values for the two conductors, from the surface to 400 m and 500 m depth, respectively.
The DIGHEM airborne survey electromagnetic data conducted by Fugro for Durango in 2011 was reprocessed and filtered by the INRS team to clarify geological structures in the area. To precisely locate the center of magnetic anomalies and to eliminate regional trends, the analytical signal data was computed from the total magnetic field and superimposed with the EM type D (bedrock) anomalies from the DIGHEM survey. The EM anomalies indicate the presence of local conductors likely to be associated with massive or semi-massive sulphides or iron formation units, which are potential traps for gold mineralization. Magnetic anomalies can mark magnetite destruction caused by hydrothermal fluids, lithological contacts and linear structures that control gold mineralization.
Based on these observations, INRS defined nine exploration targets (see Figure 1). Geophysics2017Decouverte

As reported on November 20, 2017, Danae Voormeij, PGeo, has been retained to interpret all relevant data on Découverte towards a geological model and first drill program for the Property. Ms. Voormeij states: “the recent interpretations by INRS on the ground geophysical surveys they completed are a critical component in defining and ranking drill targets for the upcoming program. The geophysical targets are being combined with field data from geological mapping and rock, till and soil sampling, previously completed at Découverte.” Additional updates on this program will be released as they become available.
The Property is in the Frotet-Evans greenstone belt, along the same shear zone as the former Troilus copper-gold mine, located approximately 60 kilometres to the northeast, which produced over two million ounces of gold and 50,000 tonnes of copper from 1997 to 2010 and has an estimated remaining resource (2016) of another two million ounces of gold. Durango is targeting orogenic shear-zone hosted gold mineralization and gold-rich VMS-style deposits at Découverte.
The Property covers a section of the main anastomosing Frotet-Troilus shear-zone where it bends from trending east-west to northeast. The dominant structural feature is a large synclinal fold nose composed of Archean metasedimentary and metavolcanic rocks that has been deformed by northwest and northeast-trending faults and intruded by syn-orogenic granodiorite bodies.
