 Gold Resource Corporation issued a positive exploration update from its properties in Mexico and also told investors it was restarting production from its Don David gold mine, where activity was ramped down last month due to the coronavirus COVID-19 pandemic. We are commencing the processes to restart production from the mine, build up a run-of-mine stockpile, restart the processing plant and return to 2021 budgeted throughput rates of 1,500 tonnes per day in the next several weeks, said Alberto Reyes, chief operating officer in a statement.
