Osisko Metals Incorporated (TSX-V: OM) (OTCQX: OMZNF) (FRANKFURT: 0B51) is pleased to announce further results from the current in-fill drill program at its Pine Point Project, located in the NWT.
The results reported herein are from the L65 Tabular deposit in the Central Zone (see Map 1 and Tables 1 & 2) and form a part of the C1 Cluster area that has recently demonstrated improved hydrogeological modelling and substantially reduced dewatering requirements (see news release dated October 27, 2021).
Following recent positive hydrogeological results and significant spot zinc price increases, the Company will remodel this area with revised cost estimates and price forecasts. The objective is to convert the underground Mineral Resources in the Central Zone to open pit mining methods similar to the other four neighboring proposed open pits in the C1 Cluster. The potential opportunity is to simplify the operational aspects and reduce mining costs for this Cluster of deposits.
Robert Wares, CEO and Chairman, commented: “The excellent infill drilling results announced today add to the significant impact of our updated dewatering assumptions. The cluster mining strategy will potentially result in a simplified mine plan in the C1 Cluster. We will be able to leverage these improvements to other clusters and possibly expand the total tonnage mined and mine life at Pine Point. Shareholders are reminded that only 39.6Mt of the larger 52.4Mt resource was utilized in the 2020 PEA. We are excited to see the final impact of the updated dewatering model in our updated PEA expected in Q1 2022.”
The L65 mineralization is shallow and flat-lying, intersected between 60 and 87 metres vertical depth. Results were consistent with respect to the current resource block model and provided partial infill spacing required for the L65 deposit to meet the Indicated Mineral Resource threshold as defined in the 2020 PEA. The holes also further confirmed historical data.
Drilling to date has been conducted where summer access was available, and the Company is now in preparation for the 20,000 metres winter drilling program.
Hydrogeological Program Update
Modelling is ongoing for the other Clusters of deposits as part of the Life of Mine Planning that will be included in the Q1 2022 PEA Update.
Two additional holes within the L65 zone have been cased with internal perforated PVC for hydrogeological purposes. Further testing is planned for December.

Quality Assurance / Quality Control
Osisko Metals adheres to a strict QA/QC program with regard to core handling, sampling, transportation of samples and lab analyses. Drill core samples from the Pine Point project area were securely transported to its core facility at the Pine Point project site, Northwest Territories where they were logged and sampled. Samples selected for assay were shipped via secure transportation to the ALS Canada Ltd.’s preparation facility in Yellowknife. Pulps were analyzed at the ALS Canada Ltd. facility in North Vancouver, British Columbia. All samples are analyzed by four acid digestion followed by both ICP-AES and ICP-MS for ultra-trace level detection for a multi-element suite with a 1% upper detection limit for base metals. Samples reporting over 1% for Zn and 1% for Pb are analyzed by assay grade, four acid digestion and ICPAES analysis with an upper detection limit of 30% and 20% respectively. Samples reporting Zn >30% and or Pb >20% are analyzed by traditional titration. Current drill program is following strict COVID19 protocols, has been underway since January 15th 2021 and is in progress. Further assay results are pending.
About Osisko Metals
Osisko Metals Incorporated is a Canadian exploration and development company creating value in the base metal space. The Company controls one of Canada’s premier past-producing zinc mining camps, the Pine Point Project, located in the Northwest Territories for which the 2020 PEA has indicated an after-tax NPV of $500M and an IRR of 29.6%. The Pine Point Project PEA is based on current Mineral Resource Estimates that are amenable to open pit and shallow underground mining and consist of 12.9Mt grading 6.29% ZnEq of Indicated Mineral Resources and 37.6Mt grading 6.80% ZnEq of Inferred Mineral Resources. Please refer to the technical report entitled “Preliminary Economic Assessment, Pine Point Project, Hay River, North West Territories, Canada” dated July 30, which has been filed on SEDAR. The Pine Point Project is located on the south shore of Great Slave Lake in the Northwest Territories, near infrastructure, paved highway access, and has an electrical substation as well as 100 kilometres of viable haulage roads already in place.
The current Mineral Resources mentioned in this press release conform to NI43-101 standards and were prepared by independent qualified persons, as defined by NI43-101 guidelines. The abovementioned Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of the reported Inferred Mineral Resources are conceptual in nature and are estimated based on limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological grade and/or quality of continuity. Zinc equivalency percentages are calculated using metal prices, forecasted metal recoveries, concentrate grades, transport costs, smelter payable metals and charges (see respective technical reports for details).
