Rockhaven Intersects 43.2 g/t Gold and 137 g/t Silver over 1.2 m and 7.4 g/t Gold and 183 g/t Silver over 4.2 m at its Klaza Project, Yukon
VANCOUVER, BC / ACCESSWIRE / January 30, 2023 / Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce additional assay results from the 2022 exploration program completed on its 100% owned road-accessible Klaza property. The Klaza property is located within the Dawson Range gold-copper belt in the southern Yukon, a prolific belt that hosts several important mineral deposits including Minto Metals’ Minto copper-gold mine, Western Copper’s Casino copper-gold deposit and Gold and Newmont ‘s Coffee gold deposit .
Program 2022
The program utilized two diamond drill rigs which completed a total of 12,042 meters of drilling in 69 drill holes. The 2022 work program focused on advancing Klaza toward an updated mineral resource estimate1 and a Pre-Feasibility Study by defining and expanding its current mineral resources and collecting data and samples to complete the engineering and metallurgical studies for the project. The first set of drill results covering drill holes that tested the structure of the Central and Eastern BRX Zone were released on January 18, 2023.
All results in this news release are from 8 holes drilled in 2022 at the Western BRX and Western Klaza Zones. Results from 39 drill holes are pending and will be released once all assay results have been received and compiled.
Statement from Rockhaven President and CEO Matt Turner:
The Western BRX and Western Klaza zones could be potentially attractive as two of the early mining centers in any development scenario being developed at Klaza, in part due to their high grade nature and excellent continuity along strike and down dip. The infill drill holes completed in these zones this summer all intersected significant mineralization. The strongest result came from the core of the Western BRX zone with a high-grade gold intercept of 43 g/t gold and 137 g/t silver over 1.2 m in hole KL-22-593. The Western Klaza zone, located 800m north of the Western BRX zone and within the same fault package, returned high-grade hits including 7.4 g/t gold and 183 g/t silver over 4.20m in hole KL-22-580 .
The West Zones
The Western BRX and Western Klaza zones are located within the same fault plate, approximately 800m apart, and represent the most distal extents of their respective mineralized structures within the Klaza deposit. Both are significant contributors to the overall precious metal endowment of Klaza.
Within the western BRX zone, strongly mineralized epithermal veins are hosted adjacent to a feldspar-porphyry vein that can be traced along the length of the zone. Since its discovery in 2011, a total of 9 dredge trenches and 85 diamond drill holes have traced mineralization over a strike length of approximately 500m and down dip from surface to a maximum depth of 520m. The mineralization remains open to extension at depth.
The Western Klaza Zone hosts a single discrete vein that has been traced for over 400m along strike and to a maximum depth of 340m down dip. A total of 8 dredge trenches and 49 diamond drill holes targeted this structure.

+ Represents core length of diamond drill hole. True widths are estimated to be 80-90% of the section as the majority of vein intersections had contacts that were at or near perpendicular to the core axis.
*Gold equivalent (AuEQ) values assume $1,800/oz Au, $22/oz Ag, $1.05/lb Pb and $1.60/lb Zn with variable recoveries for the various metals. The equation used is AuEq = 1*Au + Ag/103.42 + Pb/4.64 + Zn/3.63
QA/QC
All assays for rock and core samples from the 2022 program were completed by ALS Minerals with sample preparation in Whitehorse, Yukon and Windsor, Ontario and sampling and geochemical analysis in North Vancouver. Core samples were routinely analyzed for gold by fire assay followed by atomic absorption (Au-AA24) and 48 other elements by inductively coupled plasma mass spectrometry (ME-MS61). Samples exceeding the detection limits of routine methods were assayed for silver, copper, lead and zinc by inductively coupled plasma atomic emission spectroscopy (Ag/Cu/Pb/Zn – OG62) and for gold by gravimetric analysis (Au-GRA22). There were strict procedures related to sample collection, chain of custody and data entry. Certified assay standards, gross duplicates, field duplicates and blanks were routinely inserted into the sample stream to ensure the integrity of the assay process. All reported results passed QA/QC screening.
