Following Carrizal completing the required earn-in expenditures, a 20:80 joint venture between Carrizal (20%) and Santacruz (80%) will be formed.

"In addition, our joint venture with Carrizal is an important milestone in our plan to grow our Zacatecas operations into a significant silver producer, and we look forward to its continued development as part of Santacruz's transition into a mid-tier Mexican silver producer."

Carlos Silva, CEO of Carrizal and COO of Santacruz, stated "Carrizal is very pleased to be partnering with Santacruz on this significant mineral portfolio in Mexico," Mr. Silva continued "We intend to grow this asset base by developing a methodical and achievable mine plan and then executing it."

Rosario Project

The decisions to commence production at the Rosario Mine, Cinco Estrellas Property and Membrillo Prospect were not based on a feasibility study of mineral reserves demonstrating economic and technical viability, but rather on a more preliminary estimate of inferred mineral resources. Accordingly, there is increased uncertainty and economic and technical risks of failure associated with this production decision. Production and economic variables may vary considerably, due to the absence of a complete and detailed site analysis according to and in accordance with NI 43-101.

Veta Grande Project

Accordingly, there is increased uncertainty and economic and technical risks of failure associated with this production decision.
