ORIGINAL: Copper Lake Announces Filing of NI 43-101 Technical Report and Updated Mineral Resource Estimate for Norton Lake Nickel-Copper-Cobalt-Pge Deposit, Northwestern Ontario

2023-10-03 17:10 ET - News Release

TORONTO, Oct. 03, 2023 (GLOBE NEWSWIRE) -- Copper Lake Resources Ltd. (TSX-V: CPL, Frankfurt: WOI, OTC: WTCZF) (“Copper Lake” or the “Company”) is pleased to announce the filing of the technical report (the “Report”) for the updated Mineral Resource Estimate (the “MRE”), prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects (“NI 43-101”), on its Norton Lake Nickel-Copper-Cobalt-Palladium-Platinum Deposit (the “Deposit”), situated 50 km northeast of Fort Hope and approximately 413 km northeast of the port City of Thunder Bay, northwestern Ontario. The Report is titled, “National Instrument 43-101 Mineral Resource Estimate and Technical Report for the Norton Lake Ni-Cu-Co-Pd-Pt Property”, with an effective date of August 12, 2023, and prepared for Copper Lake by Caracle Creek Chile SpA and Atticus Geoscience Consulting S.A.C. The Report is available under the Company’s profile on SEDAR+ at www.sedarplus.ca or from the Company’s website at www.copperlakeresources.com. This news release and Mineral Resource Estimate supersedes the news release dated September 7, 2023, which reported erroneously on an earlier version of the Norton Lake Deposit mineral resource estimate.

Highlights of the current Mineral Resource Estimate (Table 1) are as follows:

  • Open pit and underground Measured + Indicated Resources of 1,795,000 tonnes at an average grade of 0.72% NI, 0.69% Cu, 339 ppm Co, 0.52 g/t Pd, 0.17 g/t Pt and containing 28.3Mlbs of nickel and 27.3Mlbs of copper.
  • Open pit and underground Measured Resources of 861,000 tonnes at an average grade of 0.66% Ni, 0.62% Cu, 326 ppm Co, 0.46 g/t Pd, 0.17 g/t Pt and containing 12.5Mlbs of nickel and 11.8Mlbs of copper.
  • Open pit and underground Indicated Resources of 934,000 tonnes at an average grade of 0.77% Ni, 0.75% Cu, 351 ppm Co, 0.56 g/t Pd, 0.18 g/t Pt and containing 15.8Mlbs of nickel and 15.5Mlbs of copper.
  • Open pit and underground Inferred Resources of 562,000 tonnes at an average grade of 0.67% Ni, 0.63% Cu, 310 ppm Co, 0.50 g/t Pd, 0.14 g/t Pt and containing 8.2Mlbs of nickel and 7.8Mlbs of copper.

“This updated Mineral Resource Estimate confirms that the Norton Lake Deposit has sufficient size, grade and expansion potential to be regarded as a significant exploration project in the North American EV metal space," stated Terry MacDonald, CEO of Copper Lake. “Additionally, the style of magmatic nickel-bearing mineralization and the favourable geological setting, indicate significant expansion potential for the deposit itself and for finding additional similar deposits elsewhere on the Property.”

The Norton Lake Deposit is hosted within the Norton Lake intrusion, a discrete sill-like mafic-ultramafic body of Archean age. Semi-massive to massive sulphide mineralization occurs in the mafic-ultramafic intrusion, at the contact between an underlying, sheared amphibolitic tuff and sedimentary rocks and an overlying sequence of mafic volcanic rocks. The Deposit is characterized by two, higher-grade semi-massive sulphide lenses within it and has been traced by diamond drilling over a strike length of close to 300 metres and to a maximum depth of 400 metres below surface. It currently remains open at depth for expansion.

  1. The independent Qualified Person for the MRE, as defined by NI 43-101, is Mr. Simon Mortimer, (FAIG #7795) of Atticus Geoscience Consulting S.A.C., working with Caracle Creek International Consulting Inc. The effective date of the MRE is August 12, 2023.
  2. These Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred Resources in this MRE are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated. However, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
  3. The MRE was prepared following CIM Definition Standards on Mineral Resources and Reserves (2014) and CIM Best Practice Guidelines (2019).
  4. 3D geological modelling revealed that the mineralization exists as a single steeply dipping continuous unit that runs along the basal contact of an ultramafic-mafic intrusion which has been sheared and brecciated.
  5. The estimation domains were defined by combining the lithology and structural models then utilizing a nickel mineralization threshold of 1.08% Ni as a proxy to define the high-grade massive sulphide domain. Geological and block models for the MRE used core assays (970 samples), data and information from 60 surface diamond drill holes (4 from Copper Lake and 56 historical). The drill hole database was validated prior to resource estimation and QA/QC checks were made using industry-standard control charts for blanks, core duplicates and commercial certified reference material inserted into the core assay batches.
  6. Estimates have been rounded to three significant figures for Measured and Indicated categories, and two significant figures for the Inferred categorization.
  7. The MRE was constrained by a conceptual open pit using the following optimization parameters, as reviewed and agreed to by the QP. Metal prices in US$: $8.00/lb nickel, $3.25/lb copper, $13.00/lb cobalt, $900/oz for platinum and $1,200/oz for palladium. An overall pit slope of 45 degrees was used. Mining and processing costs (US$) were based on benchmarking from similar deposit types, utilizing a mining cost of $4.23/t, a processing cost of C$11.54/t, a G&A cost of C$2.31/t, and considering an exchange rate of 1.30C$/US$. All resources below the conceptual pit are considered extractable via underground mining scenarios. A cut-off grade of 0.30% Ni was applied to the resource block model for the reporting of the mineral resource statement.
  8. The block model was prepared using Micromine 2020. A 4 m x 4 m x 4 m block model was created, with sub-blocks to 1 m x 1 m x 1 m. Drill composites of 1 m intervals were generated within the estimation domains, and subsequent grade estimation was carried out for Ni, Cu, Co, Pt and Pd using an inverse distance weighting (IDW) interpolation method.
  9. Grade estimation was validated by a secondary estimation method (nearest neighbour) and through comparison of input and output statistics, swath plot analysis, and by visual inspection of the assay data, block model, and grade shells in cross-sections.
  10. Density estimation was carried out for the mineralized domains using the inverse distance weighting (IDW) interpolation method within the mineralised domains and through assigning a standard value to each rock type outside the mineralised area. A total of 121 specific gravity measurements were used, and as a reference, the average estimated density value within the mineralised domain is 3.35 g/cm3 (t/m3).

Qualified Persons

The Norton Lake Mineral Resource Estimate and Technical Report was prepared by Simon Mortimer, FAIG of Atticus Geoscience Consulting S.A.C., Scott Jobin-Bevans, P.Geo, PhD, PMP of Caracle Creek Chile SpA, and John Siriunas, P.Eng., M.A.Sc. of Caracle Creek International Consulting Inc. who are all independent Qualified Persons, for the purposes of National Instrument 43-101, Standards of Disclosure for Mineral Projects. Dr. Jobin-Bevans, Mr. Mortimer, and Mr. Siriunas have reviewed and approved the technical content of this news release.

Norton Lake Ni-Cu-Co-Pd-Pt Property - Exploration Upside

Geological and geophysical evidence suggests that there is more than 11 km of strike length on the Property prospective for the discovery of additional magmatic Ni-Cu-Co-PGE mineralization. Ultramafic rocks, similar to those that host the Norton Lake deposit have been mapped on the property; accordingly, these are prospective for the discovery of similar type deposits as Norton Lake. Geological evidence at the Deposit suggests a conduit-feeder dike style of mineralization – such deposits tend to occur in clusters, auguring well for exploration potential.

The Norton Lake deposit is associated with a series of airborne geophysical conductors situated on the south flank of a magnetic high. Numerous other conductors are present in the locale of the Norton Lake deposit and elsewhere on the property, which warrant follow-up.

Legacy borehole and large-loop electromagnetic (EM) data was recently recovered for surveys completed on the Norton Lake Deposit and surrounding area. As far as known, aside from logistical reports, there was no formal interpretation of this data completed at the time of the surveys. Such data will be interpreted and modelled and will be of great assistance in directing future drill programs testing for depth extensions to the Norton Lake deposit as well as for drill targeting, in and around the known deposit in the search for additional mineralization.

Historic drilling testing the Norton Lake deposit intersected a new zone of Ni-Cu-Co-PGE mineralization, known as the South zone. Drill holes U-4 and U-14 returned drill intercepts of 0.80% Ni, 1.07% Cu and 3.2 g/t Pt + Pd over 7.0 metres and 0.80% Ni, 0.30% Cu and 1.10 g/t Pt + Pd over 5.0 metres, respectively. The South zone appears to underlie the Norton Lake deposit and has only been tested by the 2 above drill holes, both at very shallow depth. Additional drilling is clearly warranted to expand this new zone of mineralization.

Next Steps for Norton Lake

A thorough compilation of all data available for the Norton Lake property and surrounding area will be completed to prioritize targets for upcoming exploration programs. This will include the integration of legacy airborne surveys, historic diamond drilling data as well as all ground surveys that have been completed to date.

Borehole and large-loop EM data generated from an earlier exploration program testing the Norton Lake deposit and immediate locale, have been retrieved by Copper Lake. Interpretation and modelling of such data will be completed to assist in directing future drilling programs, specifically to expand on the limits of the known Norton Lake deposit and to provide targets prospective for satellite or nearby magmatic Ni-Cu-Co-PGE deposits.
