    Biricu project is located the Guerrero Gold Belt (“GGB”) which has seen several million ounces of gold discovered along this mineralized trend since the 1990s which continues to increase with further brownfields resource expansion and new greenfields discoveries.  Biricu’s proximity and geological resemblance to the Los Filos-Bermejal-Nukay gold mines in the GGB led Alamos Gold to stake the Biricu project concessions in 2010.  They were subsequently optioned to Guerrero Ventures in 2012.  Minaurum loaned Guerrero Ventures funds to explore Biricú in exchange for a controlling interest in the project in 2016.  In 2019, Minaurum acquired a 100% interest in the Biricu project.

  • The Biricu mineralization appears to be related to skarn and hornfels alteration of Mezcala Formation shale and sandstone in proximity to diorite/granodiorite intrusive rocks.  Cretaceous Morelos Formation limestone and the overlying Mezcala Formation shale are the oldest rock units in the Biricu area.   These units are exposed in a NNE-SSW-trending syncline cored by the Mezcala Formation shales, with Morelos limestone exposed on the flanks at Biricu.  Laramide dioritic stocks cut through the sedimentary rocks, most notably associated with a diatreme at the Punto Rojo prospect. 

    The transition from the limestone of the Morelos Formation to the limey shales and siltstones of the Mezcala Formation, where intruded by Laramide stocks is known to be favorable for gold mineralization in the Guerrero Gold Belt.  Mineralization may occur along the margins of the intrusive bodies, especially at the levels of the Mezcala-Morelos transition, and/or within the intrusive bodies themselves.

    Guerrero Ventures’ exploration, supervised by the renowned Guerrero Gold Belt veteran and late Minaurum director David M Jones, consisted of geological mapping, soil and rock-chip geochemical sampling, and an airborne VTEM-magnetics survey, in addition to a 21-hole, 9,587-m core drilling program carried out from 2012 to 2016. Surface mapping and sampling identified a line of intrusive rocks similar to those that host deposits in the Guerrero Gold Belt.  Airborne geophysics discerned magnetic anomalies and conductors that may indicate intrusive bodies at depth. 

    Exploration drilling testing the Punto Rojo target returned 26.98 metres (m) grading 1.07 g/t gold and 0.29 g/t silver, including 6.85 m grading 2.78 g/t gold and 0.92 g/t silver.
