Rapid Restart Potential
We believe that there is strong potential to quickly restart production, which stopped in the early 1980s, for minimal capital by focusing on the de-watered upper areas of the mine, utilizing existing infrastructure, and based on truck haulage and toll milling methods. The rapid restart would allow us to self-fund our ongoing high grade silver exploration, immediately crystalize the value created through exploration, and demonstrate our ability to successfully operate the mine based on modern techniques.- Sam Ash, CEO of Bunker Hill Mining
Our strategy is centered on rapidly restarting mining operations. We believe that this can be achieved for minimal capital by focusing on the de-watered upper areas of the mine, utilizing existing infrastructure, and based on truck haulage and toll milling methods. The prompt restart would allow self-funding for our ongoing high-grade silver exploration and immediately crystalize the value created through exploration. A PEA, to assess the potential to quickly restart production, is on track for publication in early Q2-2021.
Potential for low up-front capital costs by leveraging existing infrastructureA rapid restart program, is believed to be achieved for minimal capital by focusing on:
- Minimal development and rehabilitation work required to access initial stopes;
- Utilization of existing underground and surface infrastructure;
- No de-watering requirement to commence re-start;
- No requirement for above-ground tailings storage capacity; and
- No requirement for purchase of mobile equipment given the use of contract mining.
Potential to develop a sustainable low environmental footprint operation
The long-term water management solution to protect Lake Coeur d’Alene is integral to the PEA and is fundamental to Bunker Hill management’s vision and strategy. Our underground pre-treatment facility is near completion, and has already demonstrated measurable improvements in water quality. We are evaluating parameters of long-term water solution managed where due to the intent to not have an above-ground processing or tailings deposition, it means that minimal surface disturbance will be made, no permitting costs are required given all permits intact, and no further studies are required. The majority of tails generated are expected to be used for back-fill, with the remaining to be thickened tails and deposited in historic workings. As such, this is expected to be a sustainable approach given over 100 years of mining workings are available for use.
