Vancouver, British Columbia, October 25, 2021 – Discovery Harbour Resources Corp. (TSXV: DHR; OTC Pink: DCHRF; Frankfurt: 4GW) (the “Company” or “Discovery Harbour”) announces that the first of five drill holes results have been received from the Company’s Caldera drill program. Selected core from each of the five holes has been sent for analysis, with the next results expected in late November. The initial drill hole, CP21-01, has anomalous gold results up to 324 parts per billion gold over 1.4 metres. The drillhole intersected primarily volcanic tuffs, moderate to strong propylitic and argillic / sericitic alteration as well as multiple fault zones.

The Company completed drilling a total of slightly over 1900 metres, testing five low sulphidation epithermal gold targets (see map below) on the Caldera Property. 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.
