Zacatecas Historical Mineral Resource Estimate Information

77

In 2019 Santacruz Silver Mining Ltd. completed an updated historical resource estimate as set forth in the technical report titled “Technical Report – Veta Grande Project, Zacatecas State, Mexico” dated 20th of August 2019. The report was prepared by Van Phu Bui, P. Geo and Michael O’Brien, P. Geo, and filed on www.sedar.com (“2019 Panuco Historical Resource”). The 2019 Panuco Historical Resource reported 3,954,729 tonnes at 153 g/t Ag Eq. (136 g/t Ag, 0.14 g/t Au, 0.012 % Pb, 0.11% Zn) for a total of 19,472,901 ounces Ag Eq. (cut-off 100 g/t Ag Eq.).  The 2019 Panuco Historical Resource used “inferred mineral resources”, which is a category set forth under CIM Definition Standards for Mineral Resources & Mineral Reserves adopted on May 10, 2014.

The 2019 Panuco Historical Resource was calculating using 75 drill collars, 866 down hole surveys and 2,607 assayed samples.  A surface trench database totalling 183 trenches with 1,813 samples was used.  Resource blocks were defined using with dimensions of 20 m along strike and down dip, and 1 m across strike.  Grades for gold, silver, lead and zinc were interpolated into blocks using the following estimation algorithms: central — ordinary kriging and NW and Tres Cruces — inverse distance squared.  Assumptions used in the 2019 Panuco Historical Resource include the following metal prices: gold price of US $1,350/oz, silver price of US $16/oz, lead price of US $0.90/lb and zinc price of US $1.10/lb. The 2019 Panuco Historical Resource assumed recovering similar to the Veta Grande System being: gold at 52.2%, silver at 62.1%, lead at 87.9% and zinc at 78.6%.  The Company considers the 2019 Panuco Historical Resource relevant due to its identification and modelling of the Panuco deposit. 

The Company has not done sufficient work to classify the 2019 Panuco Historical Resource as a current mineral resource or mineral reserves, and the Company is not treating the historical estimate as current mineral resources or mineral reserves.Although the historical resource estimate is considered reliable, 8% of the drill core intervals used in the resource calculations was re-sampled and submitted these to ALS for independent assay. Further, additional data verification including resurveying of select diamond drill holes collars; review of graphic drill core logs, comparison of these logs with remaining half-cut core, and a cross-check of select geological logs agonist database entries; and a check of original ALS assay certificates against the assays and drill hole database. Remodelling of the current Panuco resource is ongoing pending receipt of check sample assays.
