Bunker Hill 2.0 Expansion Project PEA: $60M Capex Over a 13-Year Mine Life
Bunker Hill Mining Corp.'s Bunker Hill 2.0 Expansion Project in Coeur d'Alene Mining District, Shoshone County, Idaho, USA has a Preliminary Economic Assessment (PEA) outlining initial capital of $60M. The mine plan runs 13 years at about 920 koz Ag per year.
Bunker Hill Mining Corp.'s Bunker Hill 2.0 Expansion Project has reported Preliminary Economic Assessment (PEA) results for the zinc (with silver and lead) project in Coeur d'Alene Mining District, Shoshone County, Idaho, USA. It reflects Bunker Hill Mining Corp.'s (BNKR.V) latest disclosed economics for the asset.
Economics. Initial capital expenditure is estimated at $60M. All-in sustaining costs are pegged at 0.6 USD/lb Zn Payable. Economics are based on AgEq using PFS metal prices ($1.20/lb zinc, $1.00/lb lead, $20.00/oz silver).
Production and mine plan. The project envisions an underground operation. Life of mine is 13 years. Average annual production is approximately 920 koz Ag. Average head grade is M&I: 7 Mt @ 1.00 opt Ag, 2.40% Pb, 5.44% Zn; Inferred: 6.9 Mt @ 1.52 opt Ag, 2.87% Pb, 4.96 Zn.
Resources and ownership. Mineral resources: M&I: 7 Mt @ 1.00 opt Ag, 2.40% Pb, 5.44% Zn; Inferred: 6.9 Mt @ 1.52 opt Ag, 2.87% Pb, 4.96 Zn. The company holds a 100% interest in the project.

Our Analysis
- Initial capex
- $60M
costlier than 21% of 414 projects we track
- Mine life
- 13yrs
- Study price assumption
- AgEq using PFS metal prices ($1.20/lb zinc, $1.00/lb lead, $20.00/oz silver)
The value here is definitional, not exceptional. This is a scoping-level PEA, and its numbers carry the confidence you would expect from that: a capital estimate with a plus or minus 50% band, a 13-year mine life, and a project labeled Conceptual/Expansion. Nothing in the study is an outlier against the 414 projects we track. The one genuine distinction is the build cost: initial capex sits lower than 79% of that peer set. That is the fact an investor should anchor on, because it reframes everything else about the risk profile.
The funding question is the constraint that matters most. The build is small enough that it does not automatically require a syndicate, a streaming deal, or a multi-tranche equity raise. For a company with only three projects we track, that scale is the difference between a mine that can be financed and one that cannot. The flip side is that a PEA at this stage has not yet proven the orebody or the metallurgy to the standard a lender will demand, so the low capex is a necessary condition, not a sufficient one. The jurisdiction helps: the Coeur d'Alene Mining District in Idaho is a known mining address, which de-risks the permitting narrative relative to higher-risk geographies.
The study's price deck, AgEq using PFS metal prices of $1.20/lb zinc, $1.00/lb lead, and $20.00/oz silver, is a sensitivity input, not a forecast. The returns stand or fall on those assumptions holding, and a scoping study gives you limited line of sight into whether they will. The single question that decides whether this works is whether the next stage of study, and the drilling that supports it, can convert this from a conceptual expansion into a defined reserve without the capital estimate ballooning past the point where the build ceases to be financeable.
