The following excerpt is from the company's SEC filing.
, September 6, 2018 –
Bunker Hill Mining Corp.
” or “
”) (CSE: BNKR) is pleased to announce that it has filed on SEDAR a National Instrument 43-101 (“NI 43-101”) technical report on its Bunker Hill property located in Idaho’s Coeur d’Alene Mining District.
The technical report includes:
A 10-12 million ton Exploration Target comprised of the Quill/Newgard zones. For comparison purposes, the historical resource estimate for the whole Bunker Hill property is 9.1 million tons grading 5.08% Zn, 2.35% Pb and 40 g/t Ag (or 1.29 ounces per ton) (See disclosure below regarding historical resource estimate, in section titled “Exploration Target”);
Results of Independent Sampling showing grades for the Quill/Newgard zones (Levels 9 & 10) averaging 20% Zn, 14% Pb and 247 g/t Ag (or 7.90 ounces per ton), which exceed average historic grades; and
a Plan for a US$7.7 million Exploration Program to upgrade the historic resources to a NI 43-101 Indicated Resource.
Bruce Reid, CEO of Bunker Hill, stated: “This report highlights the significant exploration potential of the Bunker Hill Mine. The Exploration Target covers less than 10% of the overall footprint of the property, and the independent sampling grades from Levels 9 and 10 illustrate the opportunity to exceed historic mined grades using modern grade control methods.”
The technical report is titled, “Technical Report on the Bunker Hill Zinc-Lead-Silver Property, Coeur D’Alene Mining District, Shoshone County, Idaho, USA for Bunker Hill Mining Corp.” effective July 6, 2018, and was prepared by David Burga, P.Geo., Alfred S. Hayden, P.Eng., D. Grant Feasby, P. Eng., Richard H. Sutcliffe, PhD, P.Geo. and Eugene Puritch, P.Eng. FEC, CET of P&E Mining Consultants Inc.
Exploration data developed by previous property operators, including 1,574 historical drill hole assay intervals and 340 stope muck samples, was utilized by a 3D Leapfrog® vein modelling tool to outline an Exploration Target of 10 to 12 million tons grading a combined Pb plus Zn grade of 6% to 8% (excluding silver content).
The potential tonnages
and grades are conceptual in nature and are based on previous drill results that defined the approximate length, thickness, depth and grade of a portion of the historic resource estimate. There has been insufficient exploration to define a current mineral resource and the Company cautions that it is uncertain that further exploration will result in the delineation of a current mineral resource. The Leapfrog model is a conceptual mineralized envelope and is not intended to be a Mineral Resource Estimate. No grade capping, compositing or geostatistics of any kind have been applied.
The historical resource estimate is based on the most recent semi-annual estimate dated 1991, prepared by Mr. Bob Meyer, Chief Geologist at the Bunker Hill Mine, during the last months of production at the mine. The 1991 historic resource estimate has not been reduced by approximately 30,000 tons of production occurring between January 1 and 19, 1991. The historic resource includes proven, probable, possible and drill indicated reserves which are not consistent with current CIM definitions for “mineral reserves”. Historic resources were calculated by the following method: volumes (and then tons) were calculated by projecting out (as per definitions outlined in Section 6.4 of the technical report) from level plans of mined out areas. Grades were calculated by averaging the grades on the stope assay map from which the projections were made. Bunker Hill has reviewed the available data, including drill logs, assay certificates and additional supporting information sources, and believes that the historical resource calculation was conducted in a professional and competent manner. Bunker Hill has not undertaken any data verification of the historical data upon which the historic resource estimate is based. The historical resource estimate is the most recent resource estimate currently available regarding Bunker Hill. A qualified person has not completed sufficient work to classify the historical estimate as current mineral resources or mineral reserves. The Company is not treating the historical estimate as current mineral resources or reserves. There can be no assurance that any of the historical mineral resource estimate, in whole or in part, will ever become economically viable. Bunker Hill believes these historical results provide an indication of the potential of the properties and are relevant to ongoing exploration. The section below, titled “Planned Exploration Program” indicates, in the technical report author’s opinion, what work is required to upgrade or verify the historical resource estimate to a current mineral resource.
The Exploration Target, encompassing the Quill and Newgard zones (see Figure 1 below), only represents a portion of the area covered by the overall historical resource estimate for the Bunker Hill of 9.1 million tons grading 5.08% Zn, 2.35% Pb and 40 g/t Ag [or 1.29 ounces per ton].

A qualified person employed by the author of the technical report, P&E Mining Consultants Inc., took 12 grab samples for independent assay analysis, the results of which were tabulated in the following table in the technical report:
P&E Verification Samples Comparison Results
Bunker Hill Mine Working Value
Surface Stockpile Sample
Based on the overall average of the UTZ samples and the process plant results when running UTZ mineralization, the overall grades for the UTZ zone were estimated to run a combined grade of 6.0%.
The 051, 10, and 9 codes in the second column in the table above correspond to Level numbers as per Figure 1. The results for Levels 9 and 10, albeit from a very small sample size, indicate grades much higher than average values from historical stope assay maps derived from production stope (car) sampling upon which the historical resource estimate was based. The results for Level 5 are in line with historic stope assay map values.
Planned Exploration Program
The technical report proposes a US$7.7 million exploration program which would utilize controlled directional drilling from surface. This program would drill holes on 100 ft. centres on two fences down plunge over the full length of the Leapfrog wireframe encompassing the estimated 10-12 million tons. It is of the opinion of the technical report author that this drill hole spacing would be of sufficient density to calculate an Indicated resource estimate.
Peter Karelse, PGeo, is the qualified person under NI 43-101 who has reviewed and approved the technical information contained in this document.

Cautionary Note to US Investors
NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all resource estimates contained in or incorporated by reference in this press release have been prepared in accordance with NI 43-101 and the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) Standards on Mineral Resource and Mineral Reserves, adopted by the CIM Council on November 14, 2004 (the “CIM Standards”) as they may be amended from time to time by the CIM.
United States investors are cautioned that the requirements and terminology of NI 43-101 and the CIM Standards differ significantly from the requirements and terminology of the SEC set forth in the SEC’s Industry Guide 7 (“SEC Industry Guide 7”). Accordingly, the Company’s disclosures regarding mineralization may not be comparable to similar information disclosed by companies subject to SEC Industry Guide 7. Without limiting the foregoing, while the terms “mineral resources”, “inferred mineral resources”, “indicated mineral resources” and “measured mineral resources” are recognized and required by NI 43-101 and the CIM Standards, they are not recognized by the SEC and are not permitted to be used in documents filed with the SEC by companies subject to SEC Industry Guide 7. Mineral resources which are not mineral reserves do not have demonstrated economic viability, and US investors are cautioned not to assume that all or any part of a mineral resource will ever be converted into reserves. Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher resource category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of a feasibility study or prefeasibility study, except in rare cases. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant “reserves” as in-place tonnage and grade without reference to unit amounts. The term “contained ounces” is not permitted under the rules of SEC Industry Guide 7. In addition, the NI 43-101 and CIM Standards definition of a “reserve” differs from the definition in SEC Industry Guide 7. In SEC Industry Guide 7, a mineral reserve is defined as a part of a mineral deposit which could be economically and legally extracted or produced at the time the mineral reserve determination is made, and a “final” or “bankable” feasibility study is required to report reserves, the three-year historical price is used in any reserve or cash flow analysis of designated reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. The mine economics presented herein and derived from the PEA are preliminary in nature and may not be realized. The PEA is not a feasibility study. U.S. investors are urged to consider closely the disclosure in our latest reports and registration statements filed with the SEC. You can review and obtain copies of these filings at http://www.sec.gov/edgar.shtml. U.S. Investors are cautioned not to assume that any defined resource will ever be converted into SEC Industry Guide 7 compliant reserves.
This press release is not, and is not to be construed in any way as, an offer to buy or sell securities in the United States.
