Crystal Lake Announces Initial Diamond Drill Assay Results from Burgundy Ridge – Results Include 91.26m of 0.38% Cu, 0.30 g/t Au, 4.12 g/t Ag Near Surface on 180m Step Out
October 25, 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 results from the first two of ten drill holes in its maiden diamond drill program at Burgundy Ridge (will now be referred to as the “Ridge Zone”).
Diamond Drill Hole BRDDH19-002 (“Hole #2”) at the Ridge Zone intercepted 91.26 metres of 0.38% Cu, 0.30 g/t Au, and 4.12 g/t Ag starting at a depth of 36.7 metres. (Table 1).
Furthermore, a higher-grade core of mineralization within the 91.26 metre interval assayed 25.78 metres of 0.73% Cu, 0.63 g/t Au, 9.36 g/t Ag, and 0.11% Zn starting at 82.22 metres depth.
The first Diamond Drill Hole BRDDH19 001 (“Hole #1”) drilled on the Ridge Zone also intercepted high-grade Cu-Au-Ag mineralization with an interval of 4.66 metres at 1.35% Cu, 0.72 g/t Au, 9.04 g/t Ag, and 0.17% Zn within a broader mineralized intercept of 59.00 metres of 0.28% Cu, 0.16 g/t Au, and 2.44 g/t Ag starting at a depth of 21.00 metres downhole (Table 1).
- BRDDH19 002 (Hole #2 on the Ridge Zone): 91.26 metres of 0.38% Cu, 0.30 g/t Au, 4.12 g/t Ag starting at 36.67 metres (Table 1).
- Including 25.76 metres of 0.73% Cu, 0.63 g/t Au, 9.36 g/t Ag, and 0.11% Zn starting at 82.22 metres.
- Both Hole #1 & Hole #2 (BRDDH19 001 and BRDDH19 002) intersected copper, gold, silver, and zinc rich mineralization on a 180-metre step out from 2018’s Reverse Circulation (“RC”) drilling, and a ~40 to 85 metres down dip separation.
- A total of 7 samples (both within and outside of highlighted intervals) returned assays of >1% Cu (Table 2).
- Assays remain pending on 8 of 10 diamond drill holes completed at the Ridge Zone in 2019.
- The system remains open in all directions and at depth.
The second diamond drill hole BRDDH19-002 at the Ridge Zone, did not make it to its final target and collapsed at a depth of 147 metres due to bad ground conditions, 203 metres short of its target depth of 350 metres for the first-pass drilling.
The Ridge Zone is part of the larger Burgundy Trend, an area that received its first ever drilling on October 2018 via RC drilling (see March 7th, 2018 release). The drill pad (“Pad A1”), from which Diamond Drill Hole BRDDH19-001 (“Hole #1”) and Drill Hole BRDDH19-002 (Hole #2) were completed, is a 180-metre step out from the 2018 RC drilling location.
At the Ridge Zone mineralization vectored into a zinc-rich zone of the system SE of the collar location in Hole #1 (BRDDH19-001) with 18.78 metres of 0.31% Cu, 0.18 g/t Au, 6.00 g/t Ag, and 0.35% Zn starting at 125.52 metres. Higher grade zinc intercepts up to 1.32% Zn, 0.50% Cu over 2.00 metres and 0.72% Zn, 0.27% Cu over 1.55 metres sit within a broader 74.5 metre zinc-enriched horizon.
A seventh high-grade copper intercept was encountered below the zinc horizon in Hole #1 (BRDDH19-001) with 1.85 metres of 1.04% Cu, 0.17 g/t Au, 4.78 g/t Ag, and 0.24% Zn (Table 2). This is synonymous with high-grade copper mineralization intersected in 2018 RC drilling more than 200 metres away down plunge.
TABLE 2: Summary of high-grade copper intercepts
Maurizio Napoli, President / CEO of Crystal Lake commented:
We are happy with the results from the first two diamond drill holes drilled by any company at Burgundy Ridge (Ridge Zone). The grade and length of these intercepts is considerable given the two drill holes are shallow test holes in an area not previously tested by diamond drilling. The fact that mineralization is near surface unlike many deposits in the area is also a critical factor. Given our significant drilling step outs and stronger visual sulphide mineralization in holes that still have pending assay results on another >250-metre step out, we are pleased with the size of the system that we are starting to delineate on the Burgundy Trend.
This new drilling data in conjunction with dense hyperspectral, alteration, lithology, structural and surface data indicates that much of the widespread copper, gold, silver, and zinc mineralization at surface and open to a minimum depth of 147 metres is likely a “skarn” mineralization zone that is part of a multi-kilometre copper, gold, and silver-rich alkalic porphyry system in the greater Burgundy Trend.
Cole Evans, President / CEO of HEG commented:
Many of the world-class porphyry deposits throughout the Pacific Ring of Fire have skarn components similar to our early observations at the Ridge Zone of the Burgundy Trend. There are many “pimple skarns” in the Golden Triangle, but what makes Burgundy Ridge exciting are the initial indications of substantial size. We have made ~200 metre step outs and have intersected similar copper, gold, silver, and zinc mineralization across the Ridge Zone. It takes a large, hot, and hydrous intrusion to drive the kind of fluids needed for these conditions. Most of the world’s copper and gold comes from porphyry deposits.
The Burgundy Trend is Close to Major Infrastructure
The Burgundy Trend is located less than 20kms from the 303-megawatt AltaGas hydroelectric power facility completed in 2015. Manulife Financial and Axium Infrastructure purchased 90% of the project for net proceeds of $1.37 billion USD in 2018. The 72-megawatt Mclymont Creek Hydroelectric Plant and access road sit on the southern boundary of the Newmont Lake Project. The road which was constructed for access to these hydroelectric facilities skirts the southern boundary of Crystal Lake’s Newmont Lake property. Additionally, the Galore Creek access road runs through the northern portion of the Newmont Lake Property.
Newmont Lake ‘Project Phase 1 Exploration Programs’ Highlights - Three New Surface Discoveries Expand and Infill the Greater Burgundy Trend
Rapidly receding glaciers at Burgundy continue to expose new mineral showings on surface. Three new surface showings of significance were discovered in 2019 that were previously covered by ice and snow. These showings range from potassic altered, chalcopyrite mineralized megacrystic syenites, to hydrothermal chalcopyrite and sphalerite cement breccias with potassic altered, chalcopyrite mineralized clasts observed discontinuously over a 1,100-metre strike length.
On the southeastern end of Burgundy Ridge, a continuous 37 metre surface channel sample was taken crosscutting a sulphide-rich cemented hydrothermal breccia and 10 to 30-centimetre chalcopyrite veins at the newly exposed Green Rock showing across the general mineralization trend. The channel sample ended in strong sulphide mineralization at 37.00 metres due to snow cover. Assay results from this channel sample are pending.
