That would really cut down on transportation costs as mentioned by another poster, and I can see why that could mean why the plural in Induction furnaces. They could just produce silver/gold bars. They didn't specify what type of Dore bars they will produce. Hmmm

The rehabilitation of induction furnaces was completed in Durango and the furnaces shipped to the plant and are now on site. Some corrections were made to foundations in the filter press room to accommodate the installation of the furnaces. The electrical technician is expected to arrive soon and subsequently prepare the testing stage for the furnaces.

Construction of the building where the furnaces will be located is 90% completed. Once the furnaces are installed the Company will move from production of precipitate to production of dore bars.
