VANCOUVER - Rockhaven Resources Ltd. (TSX-V: RK) ('Rockhaven') is pleased to announce additional assay results from the 2021 exploration program at its 100% owned and road accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon.

During summer and fall of 2021, a total of 14,256 m of drilling was completed in 72 holes. The results discussed in this press release include 23 holes testing portions of the two main mineralized structures on the property, the Klaza and BRX zones, with the objective of upgrading and expanding the Klaza property mineral resources2. Results from the first 39 drill holes completed in 2021 were released on December 15, 2021 and February 7, 2022. Results from the remaining 10 holes will be announced when assays have been received, checked and compiled.

The Central BRX Zone currently comprises only a small percentage of the total mineral resources2 at Klaza, in part because it has received much less drilling than other zones in the deposit. The results announced today, combined with previously announced results from 2021 drilling at this zone, demonstrate its potential to contribute to growth of the mineral resources.

A nearby area that could also be important to growth of mineral resources is the AEX Zone, which approximately parallels the BRX Zone, 125 m to the south. Step-back drilling at the BRX Zone has intersected AEX Zone mineralization, as reported at the top of hole KL-21-553, which averaged 1.5 g/t gold over 7.65 m, starting only 5.75 m from surface.

Klaza Zone

The Klaza Zone consists of the Eastern Klaza, Central Klaza and Western Klaza zones, collectively traced for over a 2.1 km strike length. The Central and Eastern Klaza zones host a laterally extensive complex of steeply dipping veins, breccias and sheeted veinlets emplaced within a 25 to 100 m wide structural corridor. The Western Klaza Zone differs in that it consists of a single discrete vein that hosts a higher proportion of silver than gold compared with the other two portions of the zone. In 2021, eight holes were completed at the Central Klaza Zone and three holes were completed at the Western Klaza Zone, all were designed to convert inferred to indicated resources and collect material for advanced metallurgical testing. Three holes were also completed at the Eastern Klaza Zone near historical holes that contained promising intercepts. The Eastern Klaza Zone does not currently host mineral resources.
