(TSXV: BNCH) (OTCQB: CYRTF) (WKN: A2JM2X) (the \"Company\" or \"Benchmark\") is pleased to announce a new target area for porphyry potential. Sample analysis has resulted in a 4 km2 area at the Silver Pond Zone that provides alteration assemblages and large scale zonation patterns that are helping vector towards potential porphyry or high-sulphidation mineralization. This large zone of alteration has never been drilled, mapped, or effectively explored and is only 850 m northwest of the low-sulphidation mineralization at Cliff Creek and the heart of the Lawyers property, located 45 km from the world-class Kemess Au-Cu Porphyry Deposit.John Williamson, CEO commented, \"The Toodoggone district has many high-sulphidation and porphyry deposits and we are very encouraged by our initial results that point towards this style of mineralization at Lawyers. An expanded 2020 work program has been designed to further our understanding of this large anomaly in preparation to establish multiple targets for drilling\".A hyperspectral or SWIR (short-wave infrared) analysis of clay samples and detailed clay mapping was completed over a large (>4km2) advanced argillic alteration zone adjacent to the historical Silver Pond Zones. This type of alteration is related to moderate-high temperature and high acidity fluids that are typically associated with the surface expression of the fluids from porphyry and high-sulphidation systems (Figure 2). Advanced argillic alteration minerals including alunite and dickite are found throughout the area with two notable clusters: 1) numerous dickite locations in the northeast and 2) alunite-dickite in the southwest (Figure 1). Other clay minerals found on the periphery of the advanced argillic alteration include highly crystalline kaolinite and white mica. Zonation of the alteration assemblage and crystallinity within the broader alteration footprint can be used as a proxy for fluid temperature and pH, indicating fluid flow paths, with the potential to vector to a magmatic source at depth. The clay minerals show higher crystalline varieties in the southwest, indicating higher temperature fluid flow (more typical of mineralizing fluids) in th...
