Tectonic Metals Inc. announced the launch of a multi-phase metallurgical column test program to confirm low-cost heap leaching as a viable gold processing and extraction method at the Chicken Mountain bulk-tonnage intrusion target, one of six district-scale intrusion targets within the 99,840 acre, Flat Gold Project ("Flat") in southwestern Alaska. This initiative is part of the Company's ongoing 2024 value creation strategy as metallurgical testing is one of the most critical steps a company can take in successfully transforming an exploration-stage project into a profitable mining opportunity. Phase one of the 2024 program was initiated utilizing samples selected by Tectonic from historically drilled diamond core with the objective of investigating the potential for low-cost heap leaching.

Subsequent phases of the column leach test work program will utilize samples from Tectonic's 2023 diamond drill core currently stored onsite. For the phase one column test work, two composites representing general lower and higher-grade material were selected from historic ½ NQ sized drill core. The lower grade composite comprises 25 sample intervals selected from six different drill holes for 91.70 kg while the higher-grade composite includes 22 sample intervals from nine different drill holes for a total of 83.90 kg.

The testing program for both the lower and higher-grade sample composites will include assay head sample analysis, coarse and fine bottle roll leach testing, and column leach testing of minus ¾ inch material. Assay screen analyses of both head and leach tailings will be utilized to evaluate the extraction of gold at different particle sizes. The metallurgical test work is being conducted by Base Metallurgical Laboratories, under the supervision of Tectonic's Technical Advisor, Mr. Fred Lightner, P.E., a metallurgical engineer from the Colorado School of Mines with over 50 years of industry experience (+25 projects) specializing in heap leach gold project evaluation, consultation, feasibility, construction and operations.
