Bunker Hill Mining Corporation  (CSE: BNKR) is pleased to report multiple near surface significant high-grade silver intercepts, at its Bunker Hill Mine located in Idaho’s Silver Valley, USA.


Best selected intercepts include:


  • Hole 7035A: 7.6m at 165.52 g/t Ag, including 1.5m at 648 g/t Ag
  • Hole 7005: 4.6m at 126.56 g/t Ag, including 1.5m at 239 g/t Ag
  • Hole 7002: 2.0m at 178.72 g/t Ag, including 0.4m at 394 g/t Ag
  • Hole 7012: 2.1m at 163.15 g/t Ag, including 1.1m at 280 g/t Ag
  • Hole 7039: 5.8m at 127.24 g/t Ag, including 0.9m at 295 g/t Ag


A total of 10 holes were drilled, with each hole returning high grade silver intercepts. Notably, there are 5 intercepts grading over 800 g/t Ag equivalent and 2 intercepts grading over 1,000 g/t Ag equivalent. The drilling campaign continues, with more drill results expected to be released in the upcoming weeks.


Sam Ash, CEO stated: “The presence of high-grade silver in these drill results supports our thesis that significant high grade silver mineralization exists at Bunker Hill. These results, coupled with the fact that all of the intercepts are not associated with our recently published 43-101 resource, reinforces our confidence in unlocking significant value at Bunker Hill by aggressively pursuing a silver focused exploration program. In addition the proximity of these intercepts to existing infrastructure is supportive of our intention of advancing towards operational restart”.


The Company is conducting a silver focused exploration in the upper area of the Bunker Hill Mine to support its strategy of an operational restart of Bunker Hill focused on high grade silver production, underpinned by modern and sustainable mining techniques. Drilling is being conducted with core drilling from drill sites on surface and underground and is being informed and targeted using its recently completed 3D geologic model. The addition of this new drill information will be used to enhance geologic understanding and create an opportunity to target and expand mineralization in areas not currently within the 43-101 resource.

Today’s published drill results are from the first phase of the drill program. The intercepts highlighted are high grade intercepts of interest that lie outside of the 43-101 inferred resource, as shown in Figure 1 and 2 below.

Technical Information


The diamond drilling program used HQ-size core.  Bunker Hill followed standard QA/QC practices to ensure the integrity of the core and sample preparation through to delivery of the samples to the assay lab.  The drill core was stored in a secure facility, photographed, logged and sampled based on lithologic and mineralogical interpretations.  Standards of certified reference materials, field duplicates and blanks were inserted as samples shipped with the core samples to the lab. 


ALS Global was used to provide analytical services and all results comply with both NI 43-101 and industry standards. ALS Global holds an industry standard ISO 17025 accreditation, specifying general requirements for laboratory performance.
