Rockhaven Resources Ltd. announced the remaining 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 objectives of this drilling were: (1) expansion of existing mineral resources, (2) re-categorization of some inferred mineral resources into indicated mineral resources, (3) in-filling of gaps in drill patterns that are currently categorized as waste rock within existing resource areas, and (4) evaluation of exploration targets that lie outside of the known mineral resource areas. The results discussed in this are from 10 holes testing the Rusk Zone, a new vein complex that was discovered through diamond drilling in 2020. These holes focused on Objective 4 - the evaluation of exploration targets outside of the known mineral resources. All drill holes testing the Rusk Zone structure have returned significant mineralization. Highlight drill assays from the 2021 work program at Rusk are: 5.0 g/t gold and 336 g/t silver (10.8 g/t AuEq1) over 2.26 m (KL-21-523), 3.1 g/t gold and 62 g/t silver (4.3 g/t AuEq1) over 5.42 m (KL-21-542), 2.2 g/t gold and 69 g/t silver (3.5 g/t AuEq1) over 5.32 m (KL-21-559), 1.2 g/t gold and 20 g/t silver (1.6 g/t AuEq1) over 8.72 m (KL-21-560), 1.1 g/t gold and 56 g/t silver (1.9 g/t AuEq1) over 6.73 m (KL-21-558). The road-accessible Rusk Zone is located 3 km southeast of the Klaza Deposit and was first identified through soil geochemical sampling and geophysical surveys. A maiden diamond drill program in 2020 confirmed the presence of a new vein complex, with numerous high-grade gold, silver, lead and zinc veins discovered in a fence of holes drilled across the 2.6 km2 multi-element soil geochemical anomaly. m of mechanized trenching were completed before the 2021 drilling commenced. This trenching returned encouraging results from several mineralized structures located up-dip of 2020 drill intercepts, including 2.1 g/t gold, 125 g/t silver, 1.3% lead and 1.3% zinc across 8.7 m from the strongest structure. This structure has now been tested by 11 diamond drill holes, spaced approximately 50 m apart, over a 300 m strike length and to a maximum depth of approximately 200 m. The zone is open for expansion along strike in both directions and to depth. Mineralization and controlling structures at Rusk generally resemble those at other zones in the
Klaza Deposit but contain proportionally more silver and less gold on average. They typically consist of galena, sphalerite, pyrite and arsenopyrite in a quartz-carbonate gangue. At least two generations of veins have been recognized at Rusk, with the earlier set trending west-northwesterly and the second set more northerly. The northerly set often occurs along the margins of feldspar porphyry dykes. A syn- to post-mineralizing sinistral fault, trending northeasterly, offsets the zone by approximately 120 m.
