Discovers Porphyry Center... Drills 56.35m @ 0.45% Copper, 0.33 G/T Gold, And 3.44 G/T Silver

October 09, 2019, Vancouver, British Columbia – Crystal Lake Mining Corporation (TSXV: CLM OTC: SIOCF FSE: SOG-FF) (“Crystal Lake” or the “Company”) is pleased to announce the discovery of an entirely\new copper-gold (Cu-Au) porphyry mineral zone at the 72’ Zone; 2.3km northeast of the Burgundy Ridge mineralization. This represents a new copper-gold (Cu-Au) rich porphyry on the Newmont Lake Project located at the western margin of the Eskay Rift in the Heart of the Golden Triangle, British Columbia.

This discovery is 250 metres west-northwest of historic high-grade Cu-Au skarn-type mineralization drilled by the previous operator and ~2km away from newly discovered analogous mineralization on surface at the Rock Islands indicative of a potentially large porphyry system. This is the first discovery of porphyry-type mineralization at 72’ Zone, and the system remains open to depth and along trend both to the north and south. (See Figure 1).

Maurizio Napoli, President / CEO of Crystal Lake commented “We are excited to see our initial drilling campaign result in the discovery of a porphyry Copper-Gold system and expansion of the Burgundy Ridge alteration system. The 2019 program has already provided promising data to vector into the high-grade core of these large porphyry-hydrothermal systems.”

Highlights

– New Cu-Au-Ag porphyry discovery highlighted by 35 metres of 0.45% Cu, 0.33 g/t Au, and 3.44 g/t Ag from 224.88 metres – 281.23 metres in diamond drill hole STDDH19-006.

– Strong potassic alteration centre of chalcopyrite-bornite within grading 22.28 metres of 0.89% Cu, 0.71 g/t Au, and 6.65 g/t Ag from 228.00 metres – 250.28 metres in diamond drill hole STDDH19-006.

– Widespread alteration and sulphide mineralization associated with large Cu-Au-Ag porphyry systems in the region intercepted in all four holes.

– High-grade chalcopyrite-bornite mineralization is relatively shallow compared to other porphyry systems in the region.

– System may be evidence for high-grade porphyry-related skarn-type mineralization observed on surface along the entire Burgundy trend.

A total of four, widely spaced diamond drill holes tested a 700m x 300m area. All of the holes intercepted widespread sulphide mineralization and alteration styles characteristic of large porphyry Cu-Au systems. The third diamond drill hole into the target area (STDDH19-006) cut through stock-work hosted and disseminated chalcopyrite-bornite mineralization (“hypogene sulphide”) associated with a potassic alteration zone. The 56.35 metre diamond drill core interval contains 0.45% Cu, 0.33 g/t Au, and 3.44 g/t Ag. Importantly, the intercept includes a zone of intense potassic alteration and high-grade hypogene mineralization comprising 22.28 metres of diamond drill core intercepted 0.89% Cu, 0.71 g/t Au, and 6.65 g/t Ag. It is suggested that this intercept may be an early indication of the large Cu-Au-Ag porphyry system underlying the Burgundy Trend that is responsible for driving fluids that generated the high-grade skarn mineralization observed at surface along the trend. Further hyperspectral data supports the continuation of the alteration system in these directions. (See Figure 1).

The new porphyry system was identified through an extensive field mapping and spectral geology program that defined a large hydrothermal system focused around a multi-stage intrusive centre and associated hydrothermal breccias. The presence of alteration and sulphide mineralization in the adjacent diamond drill holes suggests the presence of a sizable hydrothermal system in the area. STDDH19-006 is the first hypogene-only mineralization intercepted at 72’ Zone to date.
