Minera Alamos Inc. provided a 2021 year- end summary of the ramp-up of mining activities at the Santana gold mine in Sonora, Mexico. Through the end of 2021 approximately 9,100 ounces of gold were mined and stacked on the leach pad during the first phase of the project mining activities. The total exceeded the Company's initial mine opening projections and provides a sufficient amount of mining, crushing and leaching data to allow for final optimization of the operation through the last stages of ramp-up.

Operational highlights through the end of 2021: Gold inventory moved to the leach pad - 9,100 oz; Mine production rates approaching the 100,000 tonnes of mineralized material per month initial target for the project ramp-up; Cumulative gold recovery from mineralization under leach for more than 30 days exceeds 70% with additional recovery ongoing; Total area of stacked mineralization under finished/active leaching remains in excess of 50% and continues to expand; Low reagent consumptions in line with previous test pad results (~0.2 kg/t NaCN and <2 kg/t lime).
