The miner also saw an adjusted net loss of US$500,000 for the three months, with that falling from $20.3 million in the same quarter a year earlier.

The company's EBITDA for the fourth quarter was $10.7 million, having dropped from $24.3 million.

For 2021, the company saw an adjusted net loss of US$8.6 million, with that having dropped from 2020 adjusted net earnings of US$1.6 million. For the 12-months, it saw net earnings and EBITDA of US$14 million and UYS$121.2 million, respectively, which are up 1,104% and 87%.  

"Our two producing mines—Guanacevi and Bolanitos—generated significant operating cash flow that we are using to extend mine lives and fund future growth," CEO Dan Dickson said of the full-year results.

Those two mines—as well as the Terronera feasibility stage project—are based in Mexico. The company also has growth opportunities in Chile and the US.

"Investment in the next leg of our growth, the transformational Terronera project, began last fall and is advancing well. While project financing is moving more slowly than expected, the project continues to move forward and with the receipt of financing and board approval in the next couple of months, is still expected to complete commissioning in H1 2025," he said.
