The company said the sale from the operation near Caborca, Mexico, will make up the initial 15 days of production from the now-completed heap leach pad.
The news comes just two months after Mexus confirmed the start of the high-grade ball mill. That milestone came just weeks after an announcement of the mill's test runs.
"The crew at the mine has done a great job of reconstructing our heap leach pad. The production of gold is occurring unencumbered by issues the old heap leach pad presented," said chief executive Paul Thompson Sr.
"The company and staff are meeting all timelines for production which will lead to a monthly increase of gold sales in 2021."
In addition to Santa Elena, Mexus owns rights to the Ures property outside Hermosillo, Mexico.
