Phoenix, Arizona--(Newsfile Corp. - May 14, 2021) - Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the "Company") confirms that management is unaware of any material change in the Company's operations that would account for the recent trading activity in the Company's stock.
As previously disclosed, flow rates have been reduced by the presence of carbon-dioxide and this has slowed the ramp-up to Stage-1 name plate production of 25 million pounds per annum. Water injection has been shown to remove carbon dioxide and restore flows. The current operating plan is to cycle back and forth between acid injection, water injection and recovery and this is occurring during daily operations. The Company believes the carbon dioxide is a finite problem that will be resolved over time. In an effort to speed up this process, the Company is also conducting numerous additional wellfield improvement programs including the following:
- Infrastructure upgrades to provide additional water and evaporation capacity.
- Investigating alternatives to using water as the flushing agent.
- Implementation of various field tests designed to better focus and make more efficient the remediation efforts including tracer studies, flow measuring and geophysical networks.
- Additional modelling to understand the best methods for remediation of CO2.
The Company is forecasting that 25 million pound per annum name plate production will be reached in the first half of 2022. Over 230,000 lbs of copper cathode have been produced to date, and copper production will continue as part of the ramp-up process.
