VANCOUVER, BC / ACCESSWIRE / January 18, 2023 / Rockhaven Resources Ltd. (TSXV:RK) ("Rockhaven") is pleased to announce 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.

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.

Highlights
Highlight assays from this press release include:

• 101.5 g/t gold and 107 g/t silver over 1.30 m starting at 64 m (KL-22-624)
• 2.18 g/t gold and 199 g/t silver over 13.29 m starting at 193 m (KL-22-579)
• 6.91 g/t gold and 37 g/t silver over 6.62 m starting at 29 m (KL-22-563)
• 18.85 g/t gold and 347 g/t silver over 1.11 m starting at 93 m (KL-22-576)

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.

Statement from Rockhaven's President and CEO, Matt Turner:

Results from 2022 drilling at the Central BRX Zone confirm, and build upon, earlier results. These results are expected to grow the total mineral resource at Klaza and upgrade mineral resources previously defined at inferred to the indicated category.

Additionally, eight holes that tested the eastern projection of the BRX Zone returned promising results that lie outside of the current mineral resource estimate. The main mineralized structure was intersected in all of these holes, with the best intercept returning 101 g/t gold over 1.30 m in hole KL-22-624.

Positive results were also obtained from the sub-parallel AEX Zone, located immediately south of the BRX Zone, including the strongest intercept to date from that zone, averaging 6.91 g/t gold over 6.62 m in hole KL-22-563.

Neither the AEX Zone nor the Eastern BRX Zone are currently included in the 2018 Klaza Property Mineral Resource Estimate, but Rockhaven expects that mineralization in portions of these zones will be added to the updated mineral resource estimate.

Central BRX Zone, Eastern BRX Zone, and AEX Zone

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(See July 10, 2020 Preliminary Economic Assessment on the Rockhaven website (www.rockhavenresources.com).

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.

Natural resources investments are generally volatile, with higher headline risk than other sectors. They tend to be more sensitive to economic data, political and regulatory events, and underlying commodity prices. The prices of natural resources investments are influenced by factors such as the costs of underlying commodities like oil, gas, metals, and coal. These investments may trade on various exchanges and experience price fluctuations due to short-term demand, supply, and investment flows. Natural resource investments often respond more sensitively to global events and economic data, including natural disasters, political turmoil, pandemics, or the release of employment data.
