Callinex Mines Inc. announced that it has filed a National Instrument 43-101 Technical Report dated January 18, 2021, prepared by Eugene Puritch, P. Eng., William Stone, P. Geo., and D. Grant Feasby, P. Eng., (2021 Report) for its Point Leamington Property, Newfoundland, Canada. As a result of review by the British Columbia Securities Commission, the Company issued a news release dated July 11, 2019 to clarify its disclosure relating to an Inferred Mineral Resource (Resource Estimate) contained in a previous Technical Report on the Point Leamington Property, Newfoundland, Canada dated August 15, 2016 (2016 Report) prepared by Tetra Tech Inc., an independent consulting and engineering service company. The Mineral Resource Estimate contained in the 2016 Technical Report is retracted and should not be relied upon. Instead of disclosing a current Mineral Resource Estimate in the 2021 Technical Report, the Company has disclosed a previously reported historical Mineral Resource Estimate prepared by Tetra Tech in 2013 for Raystar Capital Inc. The Inferred Historical Mineral Resource Estimate on the Point Leamington Property disclosed 14.1 Mt grading 1.90% Zn, 0.42% Cu, 1.07 g/t Au, 17.1 g/t Ag, 0.02% Pb and 1.91% ZnEq. The Historical Mineral Resource Estimate uses the term "Inferred Mineral Resources", which is a term set forth under CIM Estimation of Mineral Resources and Mineral Reserves. Even though the Historical Mineral Resource was calculated prior to updates to CIM in 2014, the Company considers the Historical Mineral Resource Estimate as relevant as it represents a key target at the Point Leamington Property. The Historical Mineral Resource Estimate was determined using data from historical drill hole assays and calculated using capped outlier raw assays, 3.0 m composites, ordinary kriging to estimate grades in 10 m x 10 m x 10 m blocks and a 4% ZnEq resource cut-off for reporting assuming an underground only Mineral Resource. To confirm the reliability and calculate a current Mineral Resource Estimate, Callinex will need to carry out representative assay validation sampling, geological interpretation and wireframing, geostatistical analysis, outlier treatment, grade interpolation, classification and reporting at a cut-off with reasonable prospects for economic extraction. The authors have not done sufficient work to classify the Historical Mineral Resource Estimate as current Mineral Resources or Reserves. The Company is not treating the Historical Mineral Resource Estimates as current Mineral Resources or Reserves. The historical estimates should not be relied upon as a current Mineral Resource Estimate and there can be no assurance that any of the Historical Mineral Resources, in whole or in part, will ever become economically viable. Callinex plans to carry out the work necessary in order to prepare a current Mineral Resource Estimate on the Point Leamington Property in the first half of 2021. Data validation from historic drill core, metallurgical recovery evaluation, updated metal prices and an open pit Resource modelling approach will be utilized for the estimate.
