RESOURCE NOTES:
Velardeña: March 2022.
“Velardeña Project Technical Report Summary” prepared by Tetra Tech. Initial Assessment for the property as defined under U.S. SEC Regulation S-K 1300. Two economic models were prepared for the Project: one includes Inferred Mineral Resources (MII Plan) in the analysis, and the second excludes the Inferred material (MI Plan). The economic model results are based on Mineral Resources that, by definition, are not Mineral Reserves, and do not have demonstrated economic viability. The TRS assumes prices of $1,744/oz gold, $23.70/oz silver, $0.97/pound (“lb”) lead (“Pb”) and $1.15/lb zinc (“Zn”). Mineral resources were calculated having an effective date of February 28, 2022, as diluted to a minimum of 0.7 meters and are reported at a $175 NSR cutoff.
Rodeo: March 2022
. “Rodeo Project Technical Report Summary” prepared by Tetra Tech. Initial Assessment for the property as defined under U.S. SEC Regulation S-K 1300. The Rodeo mine is currently in operation and the Rodeo TRS assumes a life of mine (“LOM”) starting point of November 1, 2021. The TRS assumes prices of $1,800/oz Au and $25.00/oz Ag. Mineral resources were calculated by Tetra Tech with an effective date of October 31, 2021 as shown in the Technical Report Summary. After adjusting for mineral extraction at Rodeo for November and December 2021, the estimate of mineral resources at the Rodeo Property at December 31, 2021 is shown in the table above. Aaron Amoroso, an employee of the Company and “qualified person” pursuant to S-K 1300, prepared the estimate.
