Rockhaven Resources Ltd. announced 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. 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: re-categorization of prioritized inferred mineral resources into indicated mineral resources; expansion of the total mineral resource; collection of samples for advanced-stage metallurgical test work; completion of additional geotechnical drilling for optimized open-pit and underground engineering; and 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. 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. Completed and planned engineering studies include geotechnical drilling and rock strength test work. During the 2022 program, a total of 16 holes were completed to support the open-pit portion of the planned pre-feasibility study. Holes were oriented oblique to the main zones, as previous geotechnical drilling at Klaza had mainly been done in conjunction with exploration holes designed to cut the veins perpendicular to strike.

The holes completed in 2022 were structural logged in detail to determine joint and fracture orientations and density and this data will be used to optimize the slope of pit walls. Where the geotechnical holes intersected vein structures, grade continuity within the resource models was also examined. Significant results from the geotechnical holes are summarized in Table II.

It should be noted that these holes crossed the veins at oblique angles and their intersected widths do not represent true widths. Rock strength test work on samples collected from the 2022 drill program includes uniaxial compression strength, splitting tensile strength, triaxial compressive strength and direct shear strength. These tests are currently in process.
