For Q4, Andean's revenue stood at US$31.1 million, which is down from $55.57 million for the same period a year earlier. 

The result followed Andean's sale of 1.3 million silver-equivalent ounces during Q4 at an average realised price of $23.21/oz, which compares with 2.2Moz AgEq at an average price of $24.99/oz the year prior.

Andean noted that general and administrative expenses in 2021 rose to $14.7 million from $6 million the year earlier.
