Golden Sky Minerals Corp.
(AUEN.V) (the “Company” or “Golden Sky”) is
pleased to announce the results of the 2021 soil program conducted
on its 100% owned Rayfield Property (“the Property”) in British
Columbia. The program consisted of 1,337 B-horizon soil samples
that encompassed an area of 26 km2 (~4km x 6.5km). This program was
designed to create a comprehensive database for surficial
geochemistry and to outline any soil anomalies on a regional scale.
In addition to the soil samples, a total of 27 rock samples were
collected and submitted for both geochemical and lithogeochemical
analysis.
This first-pass soil program successfully
delineated a large copper-in-soil anomaly (>100 ppm Cu) that
extends >3.0 kilometres (north to south) and up to ~1.0
kilometre wide (east to west). Within this anomaly are several soil
samples that assayed up to ~4,000 ppm Cu (0.400% Cu) (Figure
1).
“We are very pleased with the early success of
this extensive soil program on the Rayfield Property,” stated
Cameron Dorsey, VP Exploration of Golden Sky. “A broad
copper-in-soil anomaly has now been defined with similar
geological, geochemical, and geophysical characteristics that are
commonly associated with other alkalic porphyries in the Quesnel
Terrane. We are very excited to get boots back on the ground for
exploration in 2022.”
The Rayfield Project is located in the Quesnel
Trough, British Columbia’s primary copper-producing belt, which
hosts Teck Resources’ Highland Valley Mine, Imperial Metals’ Mount
Polley Mine, Centerra Gold’s Mount Milligan Mine, and Kodiak
Copper’s MPD Project (see Figure 2). The Rayfield Copper-Gold
Project is located approximately 20 kilometers east of the Town of
70 Mile House, British Columbia, and is accessible year-round by
well-maintained service and logging roads extending from BC Highway
97.

soil program overlaying airborne geophysical magnetic survey (TMI)
results. Copper assays become elevated above and adjacent to two
magnetic anomalies. Surficial geology, occurring as thicker blanket
till on the plateau and colluvium along the margins of the canyon,
is likely affecting the copper values. Intermittent copper assays
may be indicating an extension of copper mineralization to the
northwest and southeast within thick till
cover.https://www.globenewswire.com/NewsRoom/AttachmentNg/eb8f2d08-236c-448d-b81f-04c75fe77fe7

Rayfield Property 2021 Fieldwork
Highlights:
- Elevated copper-in-soil anomalies
were identified adjacent to, and overlying, several geophysical
magnetic and radiometric anomalies (Figure 1). These geophysical
characteristics are similar to those signifying other alkalic
copper-gold porphyry systems in the Quesnel Terrane. The elevated
copper grades from the 2021 soil program may indicate a mineralized
porphyry system at depth.
- Surficial geology varies across the
property, with a thick till blanket on the plateau and colluvium
along the canyon margins. As the till is typically quite thick,
slight increases in pathfinder mineral abundances are therefore
crucial in vectoring towards a target zone. Several elements,
including copper (Cu), silver (Ag), bismuth (Bi), arsenic (As) and
zinc (Zn) are closely correlated here, and are commonly associated
with porphyry deposits. The overlap of these pathfinder
elements defines a Cu-Ag-Bi-Zn-Pb anomaly that extends
approximately 1.8 kilometres (north-south) by 1.5 kilometres
(east-west), centered on a magnetic anomaly (Figure
3).
- Geological and alteration mapping
delineated several zones of intense sheeted and stockwork quartz
veining (up to 20% of rock volume) and localized brecciation
(Figure 4). Potassic alteration occurs commonly as halos bounding
quartz veinlets. The most abundant sulphide minerals observed were
bornite and chalcopyrite, associated with malachite and azurite.
Native copper was also present. A total of 27
rock grab samples were collected in 2021, with assays up to
0.45% Cu. Copper mineralization was mainly constrained to quartz
vein margins but were also present as disseminations within
intrusions of intermediate composition. The highest-grade
samples were collected near the northern limits of the 2021 soil
program in a zone that was never tested by historic drilling.
- Sheeted quartz vein orientations
strike northwest and dip moderately-steeply northeast. In zones of
stockwork quartz veining, however, veins strike east-west and dip
shallowly-moderately to the north (Figure 4). Both sets of quartz
veins are mineralized, commonly with trace amounts of bornite
and/or chalcopyrite.
- The soil sampling program also
revealed that low-moderate gold values are commonly associated with
copper-in-soil anomalies. Although the threshold for anomalous
gold-in-soil is established as >10 ppb Au, three samples assayed
from ~250-500 ppb Au (0.25-0.50 g/t Au) (Figure 5). These
higher-grade results are in close proximity to the Rayfield River
canyon, which may be the surface expression of a fault zone that
may have acted as a conduit for hydrothermal fluids enriched in
gold. The Vidette Mine area, located about 20 km to the southeast,
is marked by high-grade gold-bearing epithermal quartz veins. These
quartz veins were mined in the 1930s, with an average grade of
30-45 g/t Au. A similar system of epithermal quartz veins
enriched in gold may explain the gold-in-soil anomalies outlined in
the 2021 program.
John Newell, President and CEO of Golden Sky Minerals, states,
“We are very pleased with this initial soil work at our Rayfield
project, as we prepare the property for further exploration in
2022. Golden Sky is well funded and will continue to explore and
build upon its geological database for our district-sized,
~11,000-hectare Rayfield property. We are encouraged that this work
is just the beginning to help us reveal the property’s potential to
host a copper gold porphyry system.”
Rayfield Property 2021 Fieldwork
Highlights:
- In 1989, a 34 line-kilometer
Induced Polarization (IP) survey on the Rayfield Property outlined
several chargeability “high” zones, which were subsequently tested
by drilling programs in 1989, 1990, and 2008. Interestingly, many
of the chargeability “high” zones trend east-west within an overall
northwest-southeast trend, very similar to the orientation of the
magnetic highs and the observed quartz vein orientations (Figure
5). Importantly, due to the shallow response of the survey
(limited to ~125m depth), these anomalies are interpreted to remain
open to depth. Golden Sky believes that, with
modern exploration methods, there is significant potential to
discover additional mineralized zones at depth.
- Exploration drilling on the
property from the 1970s to the early 2000s comprised just 60 holes
(7,774.2 metres), with the majority of the holes being shallow
percussion holes typically <60 m in depth. Historic
drilling outlined a broad footprint (~450m x 2,100m) of low-grade
copper mineralization and hydrothermal alteration indicating
potential for a copper-gold porphyry
system. Further drilling is warranted to determine if
historic drilling on the Rayfield Property intersected the
higher-grade core of the porphyry system.
- 1970 Exploration Program: 31 percussion holes totalling 1,748 m
- Drillhole highlights include: 0.42% Cu over 6.1m
- 1989 Exploration Program: 8 diamond drillholes totalling 1,141
m
- Drillhole highlights include: 0.18% Cu and 71 ppb Au over 33.9
m; 0.14% Cu and 30 ppb Au over 66.7 m
- 1990 Exploration Program: 14 diamond drillholes totalling 3,337
m
- Drillhole highlights include: 0.13% Cu and 35 ppb Au over 164
m
- 2008 Exploration Program: 7 diamond drillholes totalling
1,548.2 m
- Drillhole highlights include: 0.13% Cu and <10 ppb Au over
67 m
- The Rayfield Property is
located within the Quesnel Trough, a major mineralogic belt hosting
major alkalic porphyry deposits.

quartz vein systems similar to the Vidette gold mine, ~20km to the
southeast.https://www.globenewswire.com/NewsRoom/AttachmentNg/0134e943-9be0-472c-a649-b51c0ad98e07
Figure 6: Historical induced polarization survey
(IP) from 1989 with several selected 1970 and 1989 drillhole
assays. Most holes were drilled with a vertical dip except for
those drilled in 2008. The chargeability IP anomalies correlate
well with the copper anomalies of the 2021 soil sampling program,
extending from the canyon onto the plateau, indicating the thick
till may be obscuring mineralized bedrock. Importantly, the IP
survey was limited to ~125m of depth and the chargeability
anomalies remain open to
depth.https://www.globenewswire.com/NewsRoom/AttachmentNg/e33bd97c-4973-4ed3-9a41-d4925bc1e99f
