Copper 360 says Rietberg mine development passes halfway mark, targets ore within 90 days

• Copper 360 reported underground development at its Rietberg Mine passed halfway of the 544-meter drive to 300 Level.
• Ore intersection on 300 Level targeted within 90 days, opening a defined ore block expected to supply mill feed for about three years.
• Run-of-mine output forecast to ramp to about 700 tonnes per day, enough to fill capacity at the MFP2 modular flotation plant.
• Haulage decline to 350 Level planned in parallel to expand mining face length, supporting longer-term production beyond the initial ramp-up.
