Constantine Metal Resources Ltd. provided a summary of the summer field activities and available assay results from its 2021 drill program at the Palmer Joint Venture Project, Alaska. Two diamond drill rigs were mobilized to the Palmer property in early June to complete up to 6,000 meters of drilling directed towards: i) infill drilling the down-dip inferred South Wall copper-zinc- silver-gold resource, ii) exploration drilling to explore for the fault off-set of the thick South Wall deposit and iii) geotechnical and environmental drilling to support the planned underground exploration program and provide information required to advance the project to feasibility. Drill contractor staffing issues and low drill productivity caused the Company to refocus the planned multi-purpose drilling program to ensure that the geotechnical and environmental aspects of the drill program were completed. A total of eight diamond drill holes for a total of 2,917 meters were drilled. Two drillholes (1,230 meters) were completed on the lower South Wall Zone as resource infill and hydrological information holes. The South Wall Zone includes an indicated mineral resource of 4.68 million tonnes grading 5.23 % zinc,1.49 % copper, 30.0 g/t silver, 0.30 g/t gold and inferred mineral resource of 5.34 million tonnes grading 5.20 % zinc, 0.96 % copper, 29.2 g/t silver, 0.28 g/t gold*. Drillhole CMR21-143B tested the lower part of the South Wall inferred mineral resource and intersected the mineralized horizon between 451.2 and 511.7 meters downhole with zones of semi- massive to massive sulfides and barite intervals. Significant assay results are provided on Table 1. CMR21-144, the second infill drillhole intersected chert and footwall stringer mineralization in close proximity to the Kudo fault. Assay results are pending. Six geotechnical diamond drillholes (1,687 meters) were completed in the Palmer deposit area to provide hydrological information including water volume and water quality. Monitoring wells were completed in five of the six drillholes for ongoing water monitoring. The remaining geotechnical drillhole plus the two infill drillholes were lined with slotted PVC pipe for additional hydrological studies. Seismic survey work totalling 6.7 line km was carried out on 11 grid lines in Glacier Creek valley to collect depth to bedrock information, that was followed up with a sonic overburden drilling program. Twelve sonic overburden drill holes totalling 678 meters were completed in Glacier Creek valley to determine the overburden stratigraphy, establish bedrock depths and provide hydrological information from groundwater monitoring wells. Updates to the avalanche study database were completed and will further aid in designing avalanche mitigation requirements and longer term safe locations for project infrastructure. The exploration portal access road was reviewed to provide an updated cost estimate to upgrade the switchback road to the portal site to a 10-12% grade in 2022, in preparation for the 2023 planned start of the underground exploration ramp. Three Glacier Creek monitoring stations have been established to provide seasonal stream flow information, particularly for the peak flow periods that are difficult to acquire because of the very high energy stream environment during these periods. Two weather stations are established on site that provide continuous temperature, precipitation, and wind information. The higher elevation station was upgraded to include precipitation data.
