Excelsior Mining hosted a Houston luncheon early this year. They have a copper mine in Arizona that is set to go into production in just a few months. Why copper? Global demand for copper is rising each year. If you believe a big wave of EV's is on the way, then you may want to consider this one.

Excelsior Mining Receives First Acid Delivery for Copper Production

Phoenix, Arizona--(Newsfile Corp. - August 13, 2019) - Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the "Company") confirms the first delivery of acid to the Gunnison Copper Project in southern Arizona. Excelsior remains on-schedule for first copper production in Q4 2019.

In July, Excelsior completed the construction of three new acid storage tanks and a new acid unloading facility. The new acid storage tanks have capacity for 7500 tons of sulphuric acid, providing for excess operational and purchasing flexibility. Acid deliveries commenced on August 12th and will continue on a regular basis until the tanks are full and throughout operations.

Roland Goodgame, COO, commented by saying, "The new acid deliveries are on schedule and continue to demonstrate our progress towards operations later this year. The pure sulfuric acid in these tanks is diluted down to a weak sulfuric acid mining solution via the new acid handling and delivery system. This weaker acid solution is used in the wellfield operations to leach the copper from the naturally fractured rocks below ground."
