Calibre Mining Reports Sulphide Mineralization at the Gold Rock Project

Calibre Mining Corp. (TSX: CXB) has announced its 2022 drill program results at its Gold Project in White Pine County, Nevada, located in the Battle Mountain-Eureka gold trend. The federal permit allows for exploration across a 78 km2 land parcel with numerous high-priority targets. Gold Rock, a near-surface oxide project, was the original purpose of the 2022 drill program. Infill and condemnation drilling, geo-metallurgical categorization, and structural modeling were used to de-risk Gold Rock’s oxide deposit. During the program, Calibre came across sulfide minerals in places where no drilling had previously been done. As shown in Figure 2, both limbs of the Gold Rock Anticline plunge from south to north, which indicates that these gold chutes remain open to depth. The presence of increasing arsenic, bismuth, and tellurium in numerous samples suggests a highly favorable gold environment and a large, deep-seated magnetic low, typical of Carlin-style feeders.

According to Darren Hall, President and CEO, Calibre is pleased with its Gold Rock project results. The federal permits allow sulfide treatment in the processing stage, increasing the grade potential. Shallow drilling has confirmed the existence of an oxide gold deposit similar to Calibre’s Pan mine deposit with better grades and recoveries. There could be a large, untested Carlin-style mineral system at depth, and the company is shifting its focus beyond near-surface oxide deposits. Our 100% owned Pan mine received Bureau of Land Management approval to modify the existing mining permit. The modification would add five more years of mining by expanding two waste rock areas and consolidating multiple open pits.
