The works aimed to its preparation has been resumed recently. We will discuss: ● Benefits of its location at Baksan Neutrino Observatory ● Its potential for geo-neutrino studies ● Current progress Neutrino Geoscience 2019 Yury Malyshkin et al, INR RAS 2 BNO Location BNO Nalchik Black See Neutrino Geoscience 2019 Yury Malyshkin et al, INR RAS 3 Baksan Valley Mountain Andyrchy Baksan valley Baksan Neutrino Observatory and Neutrino village Neutrino Geoscience 2019 Yury Malyshkin et al, INR RAS 4 BNO Facilities and Neutrino village Andyrchy EAS array Carpet-3 EAS array BUST Tunnel entrance Neutrino village Neutrino Geoscience 2019 Yury Malyshkin et al, INR RAS 5 Underground labs of BNO Entrance BUST’s hall Low Bkg Lab2 + Laser Interferom. 620 m – 1000 m w.e.
