The NIGHTCRAWLER tungsten occurrence is located along a west-flowing segment of Deception Creek, about 5 kilometres northeast of No Name Lakes and 71 kilometres northeast of 100 Mile House. It is the eastern extension of the Discovery-Nightcrawler trend forming the Fox-South mineralized area on the Fox property.
The area is underlain by metasedimentary rocks of the Proterozoic-Paleozoic Snowshoe Group, along the south margin of a granitic pluton informally referred to as the Deception stock.
Locally, sparse bedrock exposures include skarn, calc-silicate schist, quartz-biotite schist and quartzite, locally cut by per-aluminous, red garnet-bearing biotite-muscovite granite (Deception stock) and dikes and sills of alaskite-aplite occur. Pegmatite and quartz veins cut intrusive and metamorphic rocks and have variable orientations. Layering and schistosity show gentle to moderate dips to the southwest.
The Nightcrawler tungsten zone comprises some subcrop and outcrop, along with many large angular blocks, of scheelite-bearing skarn. Fine to very coarse-grained scheelite as fracture fillings and disseminations is accompanied locally by traces of pyrrhotite, chalcopyrite, sphalerite and molybdenite.
In 2005, soil grid sampling resulted in well-defined anomalous zone of tungsten and molybdenum along the Discovery-Nightcrawler trend and rock samples from the Nightcrawler Zone returned values up the 3.16 per cent tungsten over 1.5 metres, within an area approximately 500 metres in length and 100 metres in width.
In 2007, trenching results included 2.7 metres of 0.13 per cent tungsten tri-oxide, 3.0 metres of 0.21 per cent tungsten tri-oxide in bedrock, and up to 12.78 per cent molybdenum and 5.46 per cent tungsten tri-oxide in grab samples from tabular blocks of subcrop pulled out of the till. Diamond drilling along the Discovery (Fox)-Nightcrawler trend, in the same year, returned 5.0 metres of 0.33 per cent tungsten tri-oxide in hole 07F-03 and drill hole 07F-05 intersected three significant zones including 2.0 metres of 0.74 per cent tungsten tri-oxide, 20.5 metres of 0.08 per cent tungsten tri-oxide and 2.0 metres of 0.48 per cent tungsten tri-oxide (Assessment Report 30008).
In 2010, drill hole F10-01, collared 65 metres southeast of previous hole 07F-05, returned 0.16 per cent tungsten tri-oxide over 9.2 metres, including 1.37 per cent tungsten tri-oxide over 0.9 metre (Assessment Report 32054).
In 2014, the Creek Zone, an exposure of calc-silicate skarn and calc-silicate schist with two-mica granite, alaskite, aplite and quartz of the Deception stock was discovered along the eastern end of the Nightcrawler zone. The outcrop contained disseminated to weakly banded crystals of scheelite along with pyrrhotite and variable concentrations of sphalerite. Six samples averaged 1.97 per cent tungsten tri-oxide, 0.14 per cent zinc and 0.20 gram per tonne gold over an estimated thickness of 0.40 metres.
In 2015, drill hole F15-02 yielded 1.0 per cent tungsten tri-oxide over 5.0 metres in the Creek zone (Gruenwald, W., Desautels, P. (2016-04-15): NI 43-101 Technical Report Resource Estimate of the Fox Property, Ridley Creek Zone). In 2019, drill hole F19-01 intersected 4 metres of 0.23 per cent tungsten tri-oxide at the Nightcrawler zone (Assessment Report 38998). In 2020, drill hole F20-1 located at the northernmost location possible at the Creek zone, cut 2.12 per cent tungsten tri-oxide over 1.2 metres of calc-silicate mixed with schist at the top of the bedrock intercept (below overburden).
WORK HISTORY
The area has been explored since 1997 in conjunction with the Fox (Discovery) occurrence (MINFILE 093A 211). The property was optioned by Happy Creek Minerals Ltd. in December 2004 and an exploration program comprising grid layout, soil and rock geochemical sampling, prospecting and geological mapping was carried out in 2005, leading to the discovery of the Nightcrawler tungsten zone (Assessment Report 27886). Further soil, silt and rock sampling and prospecting continued throughout the fall of 2005, revealing a significant zone of tungsten (Creek zone) along the edge of Deception Creek, east of the Nightcrawler area (Assessment Report 28514).
Between 2006 and 2010, Happy Creek Minerals completed various exploration programs on the Fox property and associated occurrences. This work included diamond drilling programs in 2007 and 2010, totalling 4,486 metres over 16 holes over the Fox and Nightcrawler trend along Deception Creek.
During 2011 through 2014, Happy Creek Minerals continued programs of geological mapping, trenching and drilling on the Fox property, primarily throughout the Fox-North mineralized area on the east side of Deception Mountain, focusing on the Ridley Creek (MINFILE 093A 259) zone and surrounding area. Rock sampling also took place in Creek zone exposures, at the eastern end of the Nightcrawler zone (Assessment Report 35342).
In 2015, Happy Creek Minerals completed a program of airborne magnetic and radiometric surveys, soil and rock sampling, prospecting and geological mapping and metallurgical testing. In addition, eight diamond drill holes, totalling 1579 metres, were completed on the Creek zone (Assessment Report 35963).
From 2016 to 2018, Happy Creek Minerals' exploration work focused on the east side of Deception Mountain (Fox-North mineralized area), with the exception of seven diamond drill holes sunk into the South Grid zone in 2016 and 2017, and three holes drilled from the same site at the Creek zone 2017 (Assessment Reports 36792, 37368). The South Grid zone is approximately 1 kilometre south of the Discovery-Nightcrawler trend and is discussed in more detail in Fox Minfile 093A 211.
In 2019, two drill holes totalling 381.6 metres were completed on the Nightcrawler zone (Assessment Report 38998). In 2020, a further six holes totalling 981 metres were drilled at the Nightcrawler zone (Assessment Report 39409). Again in 2021, the Nightcrawler zone was the subject of 2,052.7 metres of NQ drilling in 12 holes (Assessment Report 40304).
Happy Creek Minerals' exploration programs in 2022 through 2025 focused on areas on the Fox property and adjacent mineral tenures, other than the Discovery-Nightcrawler trend.
