CAVU ENERGY METALS EXTENDS PORPHYRY PROPYLITIC ZONE BY 400M AND REPORTS 0.348% CU OVER 31.82M AT HOPPER PROJECT, YUKON
Cavu Energy Metals Corp. has released additional results from the 2022 diamond drilling at its road-accessible Hopper copper-gold porphyry project in Yukon, Canada. The Hopper project is located in the traditional territory of the Champagne and Aishihik first nations.
- Hole HOP22-DDH04 extends the known propylitic zone of the porphyry target by 400 metres.
- Mineralization occurred throughout hole HOP22-DDH04 with assay intervals including:
- 0.106 per cent Cu over 306.75 m from 25.25 m until EOH (end of hole);
- 0.348 per cent Cu over 31.82 m from 163 m, including 3.63 per cent Cu over two m;
- 0.442 per cent Cu over 15.56 m from 267.44 m.
- The highly enriched background values in the propylitic zone of HOP22-DDH04 and the higher-grade intervals within that zone are indicative of a significant porphyry copper system hosted within the Hopper intrusive complex.
"The results from HOP22-DDH04 clearly indicate the presence of a large propylitic zone, the type of alteration that commonly forms halos around the mineralized centres of porphyry systems," stated Dr. Jaap Verbaas, chief executive officer of Cavu. "It is encouraging that we intersected several higher-grade zones within the propylitic zone at Hopper because typically this type of porphyry alteration zone contains only small amounts of copper and the richer mineralization usually occurs closer to the core of the system. Alteration zones in porphyry copper systems normally form well-defined patterns and these patterns can be used to vector in on the mineralized core. We are seeing all the right ingredients for a substantial porphyry copper discovery on the Hopper copper-gold porphyry project."
Context of HOP22-DDH04
Hole HOP22-DDH04 was collared roughly 400 m east-northeast of HOP21-DDH06 which returned 116.18 m at 0.21 per cent Cu from surface before intersecting roughly 200 m of unmineralized dikes and intrusive phases. HOP21-DDH06 proved the presence of porphyry-style mineralization within alteration typical of porphyry deposits. However, it also showed that the Hopper intrusive complex contains unmineralized intrusive phases. The presence of unmineralized intrusive phases and later dikes complicates targeting but is a common feature of large porphyry systems.
Hole HOP22-DDH04 intersected various intrusive phases of the Hopper intrusive complex from 25.25 m onward until the end of hole at 332 m with enriched background content of copper (0.106 per cent Cu over 306.75 m). Strong to locally intense propylitic alteration occurs over the entire intersect with intervals of increased mineralization in veins. These are characteristic features of an outer envelope to a large porphyry system. The vein-hosted mineralization also included an isolated occurrence of secondary biotite, indicative of potassic alteration more central to a porphyry system. The hole contains several sections with higher copper and silver grades of up to 0.442 per cent Cu and 2.57 grams per tonne Ag over 15.56 m.
Drill core was halved on site. One-half of the drill core remains on site in a core storage facility. The other half of the core was bagged and security tagged and sent to ALS Laboratories for multielement chemical analysis and assay. Upon receipt of the samples, Cavu's quality assurance/quality control protocol flags any sets of samples that may not meet standards for disclosure, which are then sent back to the laboratory for reassay. All assays reported here passed ALS and Cavu QA/QC protocols.
