The property comprises production and exploration concessions, including an operating 350 tpd flotation plant, and it’s fully covered with LIDAR and high-resolution aeromagnetic and radiometric surveys, as well as detailed IP geophysics on the mine area. “Previous drilling campaigns completed by Aurico Gold and Fortuna Mining in 2014 and 2020, respectively, outlined the high-grade shoot currently being mined but also reported anomalous silver intercepts in four other target areas”. Vizsla has the option to acquire production concessions in the property from several individuals and local companies in five years by spending US$4 M on exploration and making staged payments that aggregate to US$1.5 M and 1.37 M common shares in total.

- Fresnillo plc. announced its position regarding the recent announced acquisition of Mag Silver Corp. by Pan American Silver Corp.: “Fresnillo originally acquired its stake in MAG Silver as a strategic investment in a single-asset company to support the strong partnership at Juanicipio, one of the world’s premier silver mines where Fresnillo is the operator and majority owner. Under the terms of the Agreement, subject to approval of the transaction, Fresnillo’s shareholding of over 9% of MAG Silver would convert into a shareholding of less than 1% of Pan American, a diversified, multiasset precious metals mining company. This conversion of shares does not align with Fresnillo’s strategic investment objectives nor with the interests of its shareholders and therefore Fresnillo has sold the majority of its MAG Silver shares” (Fresnillo, Zacatecas).
