Bunker Hill Geophysics Survey Identifies Large-Scale, Near-Surface Anomalies to the South of Existing Mine Footprint

HIGHLIGHTS:

• First ever high-resolution model of Induced Polarization (“IP”) geophysical data completed, revealing multiple large-scale, near-surface anomalies matching known responses of historically mined sulfide mineralization
• Rockford Target displays similar lithologic setting to the historical March stope, the single largest producing region of the Bunker Hill Mine, and is located 250’ south of the existing mine footprint
• Government Gulch (“GG”) Target includes several zones, with the largest having a similar scale and orientation to the Quill-Newgard zone, the largest ever continuously mineralized zone identified at the mine
• Shallow nature of target areas (<400 ft depth) allows for low-cost surface drilling from existing roadways
• Significant potential to increase mineralized resource above the water table through further exploration

TORONTO, Jan. 13, 2022 (GLOBE NEWSWIRE) -- Bunker Hill Mining Corporation (the “Company”) (CSE: BNKR; OTCQB: BHLL) is pleased to announce the final results of its ground geophysical program.  

Sam Ash, CEO, stated “We are excited to announce the final results of our ground geophysical survey, which indicates that Bunker Hill’s mineral endowment may extend well beyond the historic mine footprint and into the expansive 5,800 acre land package. Our analysis has identified multiple large scale, near-surface zones of potential new mineralization similar to what was historically mined, giving us confidence of possible success in future exploration campaigns.”

The geophysical program, which ended in September of 2021, has now been run through multiple inversion modeling processes to create a high-resolution 3D block model. Previously identified lithologic and structural features are well represented in the data and have allowed for Bunker Hill geologists to further refine geologic models over the program area previously generated from historic mapping programs.

Two key targets have been identified for further exploration: the Rockford Target and Government Gulch Target.

Mineralization at the Bunker Hill Mine is generally associated with 2 main structural orientations: a WNW strike for Zn-Pb-Ag massive to disseminated mineralization, (known locally as the “Bluebird” style mineralization) and a NE trend for Pb-Ag Quartz-Galena vein mineralization. 3D data collection and processing allowed for the survey to investigate both orientations in the same program. The two key anomalies identified are both tabular in nature and have WNW strikes. This orientation, along with their size and close association to known large-scale fault structures, make them similar to the mineralization identified in Bunker Hill’s current Mineral Resource Estimate, effective November 29, 2021.
