Vancouver, British Columbia, October 12, 2021 – Discovery Harbour Resources Corp. (TSXV: DHR; OTC Pink: DCHRF; Frankfurt: 4GW) (the “Company” or “Discovery Harbour”) announces that the field drilling portion of the Company’s Caldera drill program is complete. Selected core from each of the five holes will be assayed, with the initial assays expected by the end of October and further results over the following months.

The Company completed drilling a total of slightly over 1900 metres, testing five low sulphidation epithermal gold targets on the Caldera Property. Although the Company planned to test six drill targets, budget constraints resulted in the program being limited to five holes. Each hole was deeper than any previous drilling on Caldera and each site was selected to test the boiling zone, typically found at approximately 300+ metres below the paleo-surface, where precious metals are concentrated.  The Caldera gold property lies in a fertile gold region at the intersection of the Walker Lane and Northumberland Gold Belts northwest of Tonopah, Nevada.

Mark Fields, the Company’s President and CEO, stated “I’d like to commend the field personnel for a job well done. At times, particularly in the final holes, the drilling conditions proved very difficult and yet the drill contractor, working with our field crew, successfully reached the key target zone in each case. Core recovery was less than optimal in the final holes due to bad ground conditions. The original plan was to test more of the ten targets permitted for drilling; however, the difficult drilling conditions, particularly in the fifth and final, resulted in the decision  to conclude the program. We anticipate lab results as they become available, the earliest of which we expect by the end of October.”
