Rockhaven Resources Ltd. (TSX-V: RK) ('Rockhaven') is pleased to announce the final assay results from the 2022 diamond drilling program completed 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 copper-gold mine, Western Copper and Gold's Casino copper-gold deposit and Newmont's Coffee gold deposit.

2022 Program

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. Based on results received to date, Rockhaven is on track to achieve all objectives.

Drilling completed at the Central Klaza Zone in 2022 primarily focused on areas to the east and west of infill drilling done during the 2021 program. Although these areas were considered to be lower priority targets coming into 2022, all 21 holes returned significant mineralization along the targeted vein structures. The results are expected to be supportive of the potential project economics because several intercepts are higher than deposit average grade and some, like the interval averaging 7.00 g/t AuEq across 5.85 m in hole KL-22-603, are located near surface.'

In addition to the resource definition holes, the 2022 drill program included several geotechnical holes, the data from which will be used for engineering studies that will be an important part of our planned pre-feasibility study. The engineering work includes rock strength testing and slope stability studies, which are essential for optimizing pit shell design. The geotechnical holes were drilled at oblique angles to the mineralized structures, targeting primarily the hanging wall and footwall rocks and not the main mineralized structures. Nevertheless, a few of the geotechnical holes intersected the veins, producing additional assay information that will be used to support planned resource estimation. Of particular note, geotechnical hole KL-22-605 averaged 7.36 g/t gold and 136 g/t silver over 5.70 m and KL-22-622 returned a weighted average grade of 2.85 g/t gold and 41 g/t silver over 33.96 m, with individual assays of 65.8 g/t gold and 182 g/t silver over 1.07 m and 15 g/t gold and 957 g/t silver over 0.93 m, respectively.'

2Gold equivalent (AuEq) values assume $1,800/oz Au, $22/oz Ag, $1.05/lb Pb, and $1.60/lb Zn, and variable recoveries for the different metals. The equation used is AuEq=1Au+Ag/103.42+Pb/4.64+Zn/3.63

The Central Klaza Zone

The Central Klaza Zone hosts a laterally extensive complex of steeply dipping veins, breccias and sheeted veinlets emplaced within a 25 to 100 m wide by 1,300 m long structural corridor. In 2022, twenty-one in-fill holes were completed at the Central Klaza Zone. These holes were designed to upgrade mineral resources from inferred to indicated and to collect material for advanced metallurgical testing. Fourteen of the holes intersected the western portion of the zone, five targeted its eastern side and two tested deeper, beneath the central portion. All holes returned promising intercepts, with the most significant results coming from near surface hits on the eastern side, where highlights include 7.00 g/t AuEq2 over 5.85 m, 2.78 g/t AuEq2 over 5.61 m, and 3.13 g/t AuEq2 over 3.08 m.
