Rockhaven Resources Ltd. announced the first assay results from the 2022 exploration program at its 100% owned and road accessible Klaza property. The Klaza property is located within the Dawson Range Gold-Copper Belt of southern Yukon, a prolific belt that hosts several important mineral deposits including Minto Metals' Minto mine, Western Copper and Gold's Casino deposit and Newmont's Coffee deposit. During the summer of 2022, a total of 12,042 m of drilling was completed in 69 holes at Klaza.

The work program was designed to advance Klaza towards an updated mineral resource estimate1 and pre-feasibility study by attaining the following objectives: (1) re-categorization of prioritized inferred mineral resources into indicated mineral resources, (2) expansion of the total mineral resource, (3) collection of samples for advanced-stage metallurgical test work, (4) completion of additional geotechnical drilling for optimized open-pit and underground engineering; and, (5) evaluation of some of the exploration targets that lie outside of the known mineral resource areas through excavator trenching, soil sampling and prospecting. All of the results in this news release are from 22 holes drilled in 2022 within the Central and Eastern BRX zones and the adjacent AEX Zone. Results from the remaining 47 holes completed in other zones will be released in subsequent news releases.

The Central BRX Zone hosts veins emplaced along the selvages of a single feldspar porphyry dyke which runs the length of the zone. It hosts an indicated mineral resource estimate of 713,000 tonnes containing 53,000 oz gold, 2.84 million oz silver, 14.8 million lbs lead and 18.3 million lbs zinc at an average grade of 2.3 g/t gold, 124 g/t silver, 0.9% lead and 1.2% zinc and an inferred mineral resource estimate of 1,425,000 tonnes containing 79,000 oz gold, 4,656,000 oz silver, 30.0 million lbs lead and 27.4 million lbs zinc at an average grade of 1.7 g/t gold, 102 g/t silver, 1.0% lead and 0.9% zinc. Prior to the 2022 program, the Central BRX Zone had been traced for a strike length of 1.1 km, extending from the Western BRX Zone (the most significant mineralized zone identified to date on the property) to the Eastern Zones, which hosts sheeted-vein, bulk tonnage style mineralization not currently included in the Klaza Deposit mineral resources1. Drilling in 2022 confirmed and better defined the eastern projection of the BRX Zone structure.

The eight holes completed within this area in 2022, coupled with the results from past drill campaigns, have increased confidence in the continuity of mineralization within the Eastern BRX Zone, potentially leading to a 300 m long expansion of the mineral resource to the east. As final assays have only just been received, resource modelling is currently in progress for this zone. The AEX Zone, located just south of, and trending sub-parallel to, the Central BRX Zone, hosts significant potential for near surface growth of mineral resources at Klaza.

Step-back infill drilling at the BRX Zone intersected AEX Zone mineralization in multiple holes, with the best result returned from the top of hole KL-22-563, which averaged 6.91 g/t gold and 36.5 g/t silver over 6.62 m.
