TORONTO, Nov. 30, 2021 (GLOBE NEWSWIRE) — Bunker Hill Mining Corporation (the “Company”) (CSE: BNKR; OTCQB: BHLL) is pleased to announce the completion of an updated Mineral Resource Estimate (“MRE”) for the Bunker Hill Mine.

Sam Ash, CEO, stated, “We are pleased to report an updated Mineral Resource Estimate for the Bunker Hill Mine.  Most significantly, the Measured and Indicated category has increased 59% to 1.1 billion zinc equivalent pounds with higher grades for all reported metals, including a 124% increase in silver ounces and the conversion of material to the Measured category for the first time. These results reflect the excellent work by our geology team over the last few months to incorporate the final results of our Phase 2 drill program, advance the detailed digitization of historical data, and reflect a more refined geologic interpretation of Bunker Hill’s mineralization. This allows us to further optimize mine planning and engineering studies, concurrent with the finalization of our project finance process.”

In addition to preparing for the restart of mining in the upper part of the mine, the Company continues to refine its plans to explore the high-grade silver potential at depth and those new areas of interest that may be highlighted by its recent geophysical survey.

The updated MRE, effective November 29, 2021, is summarized in Table 1 below.  The previous MRE, effective March 22, 2021, is summarized in Table 2 below.  Zinc equivalent pounds (as referenced in the Highlights above) in the new Mineral Resource Estimate, effective November 29, 2021, is calculated utilizing data as presented in Table 1, as follows: (K tons) * (1000 tons / K ton) * (ZnEq % Grade) * (2000 pounds/ton). ZnEq % Grade is calculated as described in Footnote 4 of Table 1.  Utilizing the same calculation methodology with data in Table 2, zinc equivalent pounds for the previous Mineral Resource Estimate, effective March 22, 2021, are calculated as 0.7 billion ZnEq pounds in the Indicated category, and 1.0 billion ZnEq pounds in the Inferred category.

Both the Quill-Newgard and UTZ zones of the previous MRE were re-evaluated during the MRE update.  New geologic domain models were constructed based on continued digitization of development and geologic maps as well as additional drill data within the modeled area resulting in a more constrained estimated volume.

The UTZ zone was split into 2 main zones of mineralization – one in the hanging wall of the Cate fault, and the other in the foot wall, to better reflect historical development.  The Quill-Newgard zone now includes additional historic drilling from the 8-level of the mine and a more continuous shape was built to incorporate hanging wall mineralization above the 10-level.  Modeled domains were subsequently built using Maptek’s Vulcan software.  Modelled dimensions for blocks in the Quill-Newgard zone are 5’x5’x5’, as compared to 5’x5’x2.5’ in the UTZ zone, to better reflect the shallow-dipping nature of the UTZ zone’s mineralized area. 

Grade estimations were performed on each metal (Ag, Pb, Zn) across the block models independently, incorporating flagged mineral domain identifiers and constraining within their respective geologic domains.  Using detailed statistical analysis on each of the zone’s data sets, creation of domain-specific variograms was possible to assist in determining optimal search parameters.  Combined with updated CDF grade plots to identify capping values and cell de-clustering of spatially biased data, this allowed for an inverse distance cubed (ID3) estimation to be carried out on all zones with a high level of confidence.  Visual inspections, nearest-neighbor model comparisons, and weighted composites vs estimated block analysis show the model to reflect sampled grade values well.

With additional drill data, statistical analysis and completion of updated open-cycle metallurgical recovery test work, it was determined that a substantial portion of the Bunker Hill resource should be classified under the “Measured” category.  With the data density and well-correlated variograms along the geologic trend of mineralization, much of the mineralized material was estimated using numerous composites from multiple drill holes and channels.  Further optimization runs on resource classification definitions show that the selected criteria are consistent with the sampled data and adhere to the geologic model.

A cut-off of $70 per ton on a net smelter return (NSR) basis was selected, which the Company believes is consistent with the reasonable prospect of economic extraction.  This also leads to a reported zinc grade, that is similar to the average mined grade in the Preliminary Economic Assessment (filed on November 3, 2021), which results in minimal effect on mining parameters used in previous work-flow models.  Further locked-cycle metallurgical testing and optimization may affect NSR cut-offs applied in future resource updates.

Sensitivity of the Mineral Resource Estimate to metal price fluctuations is illustrated Table 3 below.  The same technical parameters used in Table 1 were used in this analysis.

Note: MRE metal price sensitivity figures calculated using identical cutoff ($70/ton) of updated MRE effective November 29, 2021. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution.  These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.

Patriot Battery Metals Announces Aggressive Follow-up Drill Campaign at the CV5-6 Pegmatite, Corvette-FCI Property, James Bay, Quebec

VANCOUVER, British Columbia, Jan. 20, 2022 (GLOBE NEWSWIRE) — Patriot Battery Metals Inc. (the “Company” or “Patriot”) (CSE: PMET) (OTCQB: RGDCF)…

VANCOUVER, British Columbia, Jan. 20, 2022 (GLOBE NEWSWIRE) — Patriot Battery Metals Inc. (the “Company” or “Patriot”) (CSE: PMET) (OTCQB: RGDCF) (FSE: R9GA) is pleased to announce its 2022 exploration plans for the Corvette-FCI Property (the “Property”) located in the James Bay Region of Quebec. The exploration will focus on delineation of the spodumene pegmatite occurrences on the Property, and specifically target the CV5-6 spodumene pegmatite where the first drill hole by the Company on the Property returned 0.93% Li2O and 114 ppm Ta2O5 over 146.8 m (CF21-001). Core sample assays for the remaining three drill holes that targeted the CV5-6 Pegmatite during the 2021 program are pending receipt from the lab.

The Company is currently planning a 15,000 to 20,000 m two-drill rig campaign to aggressively follow-up on the success of the 2021 drill program. The 2022 drill campaign will be completed in two phases – winter/spring and summer/fall. The winter/spring phase is expected to begin in late February and will target the areas northeast and along strike of CV5-6, beneath a shallow lake, and extend to the CV1-2 pegmatites outcropping on the opposite shore. The primary objective will be to test for mineralized pegmatite along strike, potentially connecting CV5-6 with CV1-2, as well as testing the mineralization at depth. The summer/fall phase will focus on continued land-based infill and step-out drilling around CV5-6 and CV1-2.

The Company also intends to drill test several other spodumene pegmatite occurrences on the Property as well as complete follow-up drilling along the Maven Copper-Gold-Silver Trend. The Company completed 1,177 m over ten (10) drill holes at the Maven Trend in 2021 with core sample analysis for all holes yet to be received.

In addition to the drill campaign, the Company intends to complete LiDAR and/or satellite imagery acquisition over the core areas of the Property, as well as geological mapping to aid in regional exploration and geological modelling. Regional prospecting over a recently acquired claim block, located contiguous to the eastern claims of the Property, will also be completed.

In late 2021, the Company completed a strategic financing, securing $11M in flow-through to fund significant work programs on the ground at Corvette-FCI. The Company is well funded in both, flow-through dollars and hard dollars and is now in a strong position to focus on aggressively advancing this new lithium pegmatite discovery with an overarching objective of building an initial mineral resource estimate by the end of 2022.

As previously noted, core sample assays have yet to be received for the remaining drill holes of the 2021 program (CF21-002 through CF21-014). Analytical laboratories in the industry continue to be constrained, which has dramatically impacted turn-around times on the order of weeks to months. The Company is in close contact with the lab and expects final geochemical results to be issued for the next batch of holes over the next 4 -6 weeks.

HIGHLIGHTS:

  • Significant intersections from the first follow-up drillhole (BMDD020) at Alba include:

    264.7m1 at 0.49g/t gold and 0.13% copper, from 95m to end of hole; including:

    • 7.0m at 1.77g/t gold, from 126m;
    • 9.1m at 0.91g/t gold and 0.16% copper from 173m;
    • 7.8m at 0.81g/t gold and 0.15% copper from 185m; and
    • 21.0m at 0.91g/t gold and 0.17% copper from 203m.

  • Further follow-up drilling is underway, and assays are pending for 3 drillholes.

Hole BMDD020 is only the second hole drilled at the Alba gold discovery, returning a 193.7m porphyry intersection grading 0.5g/t gold and 0.16 per cent copper from 164m. Mineralization remains open at depth.

Hole BMDD020 was drilled below maiden hole BMDD012, which returned 111m at 2.3 g/t, including 7.2m at 26.88 g/t (see Cornerstone news release 21-20 dated November 18, 2021). Hole BMDD020 also intersected the Upper Gold Zone returning 7.0m at 1.77g/t gold.

The results indicate that the Alba discovery comprises a gold zone sitting above a well mineralized gold-copper porphyry that remains open and largely untested. The Upper Gold Zone is currently interpreted to be a structurally controlled epithermal system. A geological model is being developed for this system, but the current understanding is shown graphically in Figures 3 and 4. Petrographic studies are underway.

Visible gold was identified in drill holes BMDD012 and 020 (Figure 2), and importantly in BMDD020 it was observed in both the Upper Gold Zone and within the broader porphyry zone leading to the potential for future high grade gold intervals.

Additional follow-up drill holes BMDD021 and 022 at Alba have been completed, and hole BMDD023 is well advanced (Figures 3 and 4) and are being sampled for laboratory submission. All holes have intersected rock types and alteration similar to that documented in holes BMDD012 and 020. The drill holes appear to have drilled the equivalent of the Upper Gold Zone (significant anhydrite veining), and well developed stockwork at depth with some visible copper sulphides representing the porphyry zone.

Cornerstone VP Exploration, Yvan Crepeau said:

“The latest results provide further indications that Alba is emerging as a major discovery, and demonstrate the presence of an Upper Gold Zone above a well-mineralized porphyry.

“These are some of the best porphyry gold-copper results we have seen in the broader Bramaderos Project. We are also seeing local visible gold within the porphyry system, which is highly encouraging.

“The Upper Gold Zone at Alba will be further defined as we undertake additional drilling. It is likely to be structurally controlled, and we are testing NE and N-S oriented structures from interpretation of magnetics.

“We are also undertaking detailed electrical geophysics to help map the distribution of the Upper Gold Zone, and the porphyry mineralization. We are getting hints that there is lateral continuity, and the target area is wide open.”

* The reader is cautioned that there has been insufficient exploration to define a mineral resource at Bramaderos and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

Visible gold was also identified in drill hole BMDD013 and correlated with an interval of 2m at 2g/t gold, located approximately 100m from the BMDD012 and BMDD020 Upper Gold Zone intervals.

The Upper Gold Zone is currently interpreted as a late-stage gold-rich event superimposed over a broad and deeper gold-copper porphyry mineralized system. The grades in the porphyry system in BMDD020 are some of the best seen at Bramaderos since project operator Sunstone commenced drilling. This is very encouraging as exploration is advanced across the broader Alba target.

Planned Geophysics

A conventional IP survey comprising 6 x 1,600m long lines has been planned for the Alba target and is expected to commence in late January. A 3-D Magnetotellurics (MT) survey will also be undertaken over the Alba target. MT is a geophysical method which uses natural time variations of the Earth’s magnetic and electric fields to measure the electrical resistivity of the sub-surface. Application of MT in exploration for porphyry systems has advanced significantly over the last several years and it is anticipated that the combination of MT and conventional IP will deliver multiple drill targets for both porphyry gold-copper mineralization and overprinting epithermal systems, as currently interpreted at Alba.

About Bramaderos

Measuring 4,948 hectares, the Bramaderos project is ideally located immediately adjacent to the Pan American highway, and within reasonable distance of available hydropower, supporting the economics of potential development opportunities. The project is also supported by nearby commercial airports and significant cities (Loja) and enjoys strong community support.

The Bramaderos concession is owned by La Plata Minerales S.A. (“PLAMIN”), which in turn is owned 87.5% by Sunstone (the project operator) and 12.5% by Cornerstone.

Cornerstone’s 12.5% interest is carried by Sunstone through to the start of commercial production and repayable at Libor plus 2% out of 90% of Cornerstone’s share of earnings or dividends from the Bramaderos project (see news release 20-01 dated January 7, 2020).

Qualified Person:

Yvan Crepeau, MBA, P.Geo., Cornerstone’s Vice President, Exploration and a qualified person in accordance with National Instrument 43-101, is responsible for supervising the exploration program at the Bramaderos project for Cornerstone and has reviewed and approved the information contained in this news release.

Sampling and Assaying

Surface and drill core samples from Brama were sent to the LAC y Asociados Cia. Ltda. Sample Preparation Facility in Cuenca, Ecuador for sample preparation. The standard sample preparation for drill core samples (Code PRP-910) is: Drying the sample, crushing to size fraction 70% <2mm and splitting the sample to a 1000g portion by riffle or Boyd rotary splitter.  The 1000g sample is then pulverised to >85% passing 75 microns and then sent to the MSALABS in Langley, BC, Canada for gold and base metal analysis.

PLAMIN uses a fire assay gold technique for Au assays (FAS-111) and a four acid multi element technique (IMS-230) for a suite of 48 elements. FAS-111 involves Au by Fire Assay on a 30-gram aliquot, fusion and atomic absorption spectroscopy (AAS) at trace levels. IMS-230 is considered a near total 4 acid technique using a 0.25g aliquot followed by multi-element analysis by ICP-AES/MS at ultra-trace levels. This analysis technique is considered suitable for this style of mineralization.

Standards, blanks and duplicates are inserted ~1/28 samples. The values of the standards range from low to high grade and are considered appropriate to monitor performance of values near cut-off and near the mean grade of the deposit. The check sampling results are monitored and performance issues are communicated to the laboratory if necessary.

Sample security was managed through sealed individual samples and sealed bags of multiple samples for secure delivery to the laboratory by permanent staff of the joint venture. MSALABS is an internationally accredited laboratory that has all its internal procedures heavily scrutinized in order to maintain their accreditation. MSALABS is accredited to ISO/IEC 17025-2017 Accredited Methods and certified to ISO 9001-2015.

PLAMIN’s sampling techniques and data have been audited multiple times by independent mining consultants during various project assessments. These audits have concluded that the sampling techniques and data management are to industry standards. All historical data has been validated to the best degree possible and migrated into a database.

Rock samples are collected by PLAMIN’s personnel, placed in plastic bags, labeled and sealed, and stored in a secure place until delivery by PLAMIN employees to the LAC y Asociados ISO 9001-2015 certified sample preparation facility in Cuenca, Ecuador.

Rock samples are prepared crushing to 70% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 75 microns (200 mesh) (MSA code PRP-910). Prepared samples are then shipped to MSALABS, an ISO/IEC 17025-2017 Accredited Method company and ISO 9001-2015 laboratory in Langley, BC, Canada, where samples are assayed for a multi-element suite (MSA code IMS-136, 15.0 g split, Aqua Regia digestion, ICP-AES/MS finish) and gold by Fire Assay (MSA code FAS-111, 30 g fusion, AAS finish). Over limit results for Cu (>1%) are systematically re-assayed (MSA code ICF-6Cu, 0.2 g, 4-acid digestion, ICP-AES finish). Gold is assayed using a 30 g split, Fire Assay (FA) and AAS finish (MSA code FAS 111).  Over limit results for Au (>10 g/t) are systematically re-assayed (MSA code FAS-415, FA, 30g., gravimetric finish).

Soil samples are dried at low temperature, screened to 80 mesh (MSA code PRP-757); a 15 grams portion is then assayed for a multi-elements suite (MSA code IMS-136, Aqua Regia digestion, ICP-AES/MS finish).

Quality Assurance / Quality Control (QA/QC)

MSALABS is a qualified assayer that performs and makes available internal assaying controls. Duplicates, certified blanks and standards are systematically used (1 control sample every 20-25 samples) as part of PLAMIN’s QA/QC program. Rejects, a 100 g pulp for each rock sample, are stored for future use and controls.
