Key Copper Porphyry Indicators At Passiflora Project

VANCOUVER - Viscount Mining Corp. reported on the recent drilling progress at our Passiflora project in Silver Cliff, Colorado. During drilling activities on the first deep Passiflora core hole the field geologists observed compelling geological features that suggest a potential for valuable deposits in copper porphyry systems. While drilling between 450m and 970m depth, the team began to suspect that alteration types typically found in copper porphyry systems might have been overprinted-an indication of a complex and potentially significant mineralization process. To investigate this further, six thin sections were prepared from core samples within this depth range. These thin sections reinforce the original hypothesis that this is a potential copper porphyry.

The analysis of these thin sections revealed intriguing findings, confirming the presence of overprinting. Minerals that are typically associated with distinct alteration types were found in close association with one another. Notably, biotite and chlorite were observed on the same slides, a common occurrence in porphyries that points to multiple stages of alteration. Additionally, evidence of finely interstitial sulfides was noted, and a sample was identified to contain tourmaline, a mineral commonly found in porphyry systems.

The term "presence of overprinting" refers to a geological process where different stages of alteration (or changes in mineral composition) overlap or occur in the same rock. In this context, it suggests that the minerals you would typically find in one type of alteration zone are present in the same rock sample as minerals from another alteration zone. This can happen when new mineralization events or processes "overprint" or replace earlier ones.

In a copper porphyry system, different alteration zones (phyllic, propolytic, albitic and andargillic) usually have specific minerals associated with them.

The first drill hole completed to a downhole depth of 1143m at the Passiflora intersected continuous sulphide mineralization throughout the entire length of the hole. The drill hole which identified disseminated sulphides as well as more massive zones and abundant veins are present over an interval of 1100m. Biotite was noted at 125 m and Argillic alteration was encountered below the overburden, and around 200m it seems to change to phyllic alteration. Sphalerite was noted tentatively at 213m but more confidently further down the hole. Chalcopyrite was first identified at 465m. Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS2. It occurs in all copper porphyry deposits and is the main copper mineral in the porphyry systems. Magnetite was noted in trace amounts at 680m followed by galena at 854m. Much of the hole after showed abundant overprinting of different types of alteration. Also, three mineralized breccia zones were identified during preliminary logging.

Jim MacKenzie, CEO, said, "The current work by our geologists continues to prove out the confidence that a porphyry style deposit may be reason for the geophysical anomaly. We will keep investors updated on further developments as we continue to analyze the data and advance our exploration efforts. The overprinting of alteration types seen in the core suggests that we are in an exciting phase of exploration, and we look forward to sharing additional results as they become available."
