    Red River ramps up exploration at Thalanga

    Red River Resources (ASX: RVR) announced that the company is increasing exploration activities at its Thalanga Operations in northern Queensland, following wet season.

    RVR said that Thalanga microgravity survey has commenced, targeting copper-rich base metal mineralisation at Thalanga Range and Coronation.

    The company said that Thalanga Range survey is targeting polymetallic massive sulphide mineralisation along strike from Thalanga deposit while Coronation survey is targeting copper-rich massive sulphide mineralisation in an area approximately 4km NW of historic Highway-Reward copper deposit.

    Red River said that it will use survey data to determine new targets for drilling later in 2021.

    Previous exploration at Thalanga

    The company had previously conducted exploration (IP and surface geochemistry) to define massive sulphide targets along the Thalanga Range and drilled several of these targets.

    The drilling had intersected extensive alteration and disseminated to low-grade mineralisation, indicative of the presence of large-scale footwall alteration/feeder systems. All holes also intersected zones of pyrite-chalcopyrite-galena-sphalerite veins and stringers, being indicative of feeder zones known to be associated with massive sulphide mineralisation at Red River’s Thalanga and Far West deposits. However, to date, drilling had not located base metal-rich massive sulphide deposits.

    The Thalanga massive sulphide deposit is located within the rhyolites and volcaniclastic rocks of the Mount Windsor Volcanics, at or close to their contact with the dacitic rocks of the Trooper Creek Formation. To date, total production from the Thalanga massive sulphide deposit (Thalanga, West 45 and Far West) is approximately 5.9Mt @ 1.6% Cu, 2.5% Pb, 7.5% Zn, 66 g/t Ag & 0.5 g/t Au.

    Microgravity survey commenced

    The company announced that it has now commenced a micro gravity survey, targeting polymetallic and copper-rich massive sulphide mineralisation at Thalanga Range and the Coronation prospects to define potential massive sulphide drill targets to be followed up later in 2021.

    Thalanga range deposit

    RVR said that its Thalanga Range micro gravity survey is targeting the favourable host horizon for Thalanga-style volcanic-hosted massive sulphide (VHMS) deposits along the southern side of the Thalanga Range to the west of the Thalanga mine.

    Coronation deposit

    The company said that its Coronation micro gravity survey is targeting an area 4km NW of the Highway Reward deposit (3.5Mt @ 5.7% Cu & 1.1 g/t Au), which is highly prospective for similar copper-rich massive sulphide mineralisation.

    RVR said that the exploration program aims to increase production and/or extend mine life at Thalanga, which produces zinc, copper, and lead concentrates, with gold and silver credits.

    Red River said that it believes that the microgravity survey will help to determine if there are any positive gravity anomalies (which could represent massive sulphide mineralisation) associated with the large-scale footwall feeder systems.

    Next steps

    RVR said that on completion of the microgravity survey, it will review the data generated in conjunction with previous exploration data (IP and surface geochemistry) to determine priority targets for follow-up drilling later in 2021.
