The mine shut after a silver price fall from US$42/oz to US$8/oz made environmental upgrades of processing and smelting operations prohibitive. Post Superfund site remediation, and a revamped ex Barrick management team plus government support, the Bunker Hill Mine requires no major permits to restart mining operations. The 2Q21 PEA outlined a low cost US$42m build for production of ~41kt ZnEq pa (~4.4Moz AgEq) over a 10-year mine life from a mining inventory of 5Mt @ 9% ZnEq (52Moz @ 328g/t AgEq), a subset of the 9.1Mt @ 8.0% ZnEq resource (85Moz @ 289g/t AgEq). Bunker is infill drilling while concurrently aiming to bulk out high-grade silver resources by drilling high-grade silver vein offsets and extensions at Sierra Nevada (340-500g/t) and Caledonia (685-1030g/t) veins. The goal is to take those to reserve with lower cost UG drilling once in production, bulking out the mine plan from there. Figure 1.

Despite securing an agreement with the Environmental Protection Agency (EPA) to operate the Bunker Hill mine, ending 14 years of Superfund litigation, the company quickly ran into financial trouble as former shareholder Bobby Genovese ultimately accepted a permanent penny-stock ban from the SEC for share price manipulation. The step-change came with a clean management slate, concurrent with share consolidation, and several key financings. Essential to Bunker’s transformation was former Barrick COO Richard Williams joining as Chairman, and former Barrick GM, Sam Ash, as CEO in 1H20, along with Brad Barnett as VP Sustainability, former head of closure for Barrick. Management cleaned up the balance sheet in 2020, reducing debt, renegotiating the purchase price down by 30%. Digitisation of the project’s historical data into a 3D model then formed the basis of the maiden MRE in 3Q20. This formed the foundation for the current 1Q21 MRE, and also identified several new high-grade silver exploration targets in the upper levels of the mine, themselves the subject to drilling underway now.

The evolving environmental landscape and modernizing costs ultimately drove the closure. The EPA declared it a Superfund site, with over $200m spent by 2007 on clean up and water management. That process expanded to the entire Silver Valley, using funds from two large court settlements. The restart gained momentum in 1Q18 when Bunker Hill secured the right to operate the mine without incurring liability for prior contaminants migrating from the mine in exchange for annual cash payments over seven years totalling US$20m. The new PEA excludes an onsite smelter. To date, Bunker Hill has successfully reduced the metal content released from the mine by ~70%, with a long-term solution for sustainable water management over the life of the mine once underground access is put in place. Figure 3. Bunker Hill asset history summary 1885 to present Source: Bunker Hill Step 2: Management cleanout adds tier-one leadership and governance, with technical mine building skills The Bunker Hill management team is here to build a company, hence understanding the DNA is key. A key interim issue was Bunker’s past association with Bobby Genovese, a large shareholder who settled with the SEC in 2019 over trading in the Liberty Silver era in 2012. Cutting ties completely, the new team’s backbone is the ex Barrick trio; Chairman Richard Williams, former COO of Barrick who handpicked Sam Ash, former GM who led the successful turnaround of the Lumwana Copper mine for Barrick, and Brad Barnett, experienced in managing several of Barrick’s Superfund sites.
