Norden Crown Metals Corp. ("
Norden Crown" or the
"
Company") (TSXV: NOCR, Frankfurt: 03E) has
completed a field evaluation campaign at the Smart Creek
Gold-Copper Project, including targeted geological mapping as well
as opportunity recognition work at both the Smart Creek and Sunrise
Mountain Claims, located in the Eocene Porphyry Belt of western
Montana (Figures 1-4).
Norden Crown CEO Pat Varas stated “In addition
to an excellent property-scale copper and gold metal endowment, our
technical team has focused on a variety of porphyry-related
mineralization styles in the Smart Creek / Sunrise project area and
has concluded that the present erosion level offers several
opportunities to test, high-grade copper and gold mineralized
targets. The systems are well-preserved and have large alteration
footprints, which demonstrate the potential for large deposits.
This, combined with the abundance of reactive host rocks that can
yield high grades indicates there is the potential for the
discovery of ore deposits in the area that are best
in-class.”
At the Smart Creek Project, Norden Crown is
focused on four robust zones of alteration and mineralization
areas/domains that represent compelling exploration targets
including the porphyry copper targets previously tested by Rio
Tinto. Norden’s team recognized preservation of the host
stratigraphy, which provides the opportunity for additional
porphyry (and related) targets, including structurally
controlled/replacement style gold targets at the Sunrise mine
(Figure 1).
In addition, exploration opportunities are
recognized on the Smart Creek project with potential for carbonate
replacement style mineralization (CRD) at the Smart Creek target
and at Sunrise including copper, gold and silver replacement bodies
near and associated with the historic Sunrise Mine, as evidenced by
widespread marbleization and skarn development associated with
manganese oxides and copper oxides in the carbonate metasedimentary
rocks of the Helena formation.
The Smart Creek copper target remains a
high-priority target with widespread, high grade copper oxides (and
sulphides) which outcrop at surface. This mineralization is cut by
numerous historic drill holes, with multiple copper intercepts from
surface e.g., 109.73m @ 0.75% Cu; 18.74 g/t Ag(SMCR0022; see below)
1,2.
The Smart Creek Project was optioned from Rio
Tinto (see August 20, 2024 News Release:
https://nordencrownmetals.com/_resources/news/20240820.pdf). Smart
Creek is accessible year-round via highway and gravel roads, and is
located 100 km southeast of Missoula, Montana (Figure 1).
Gold-Copper exploration potential is considered excellent at Smart
Creek:
- A total of 52 previous drill holes
(7 at Sunrise, 45 at Smart Creek). Recent drilling in 2022 by Rio
Tinto resulted in - copper assay results including a 109.73m @
0.75% Cu and 18.74 g/t Ag intercept (drill hole SMCR0022; see NR
dated August 20, 2024) 1,2.
- Extensive high-grade oxide and
sulfide copper mineralization throughout the property. Historical
rock samples with copper grades ranging from below detection limits
up to 5.64% Cu with historical mining at Smart Creek, Sunrise and
at the Henderson Gultch placer mining operations3,4.
- Historic mining of a gold-copper
replacement-style deposit at the Sunrise Mine5.
- Preservation of the
porphyry-skarn-CRD-epithermal environments on the property.
Geological mapping observations include exotic copper
mineralization, high-sulfidation style gold showings, skarn/CRD
replacements, and widespread porphyry-style, mineralization and
veins. The property features multiple targets with limited
drilling, untested by modern methods.
- A large database of airborne
magnetic/radiometric/Induced polarization and historic soil and
rock sampling, RC and diamond drilling with significant, untested
geochemical anomalies coincident with alteration zones (Figure
3)2.
- Superb reactive host rocks (Helena
Formation calcareous metasedimentary rocks); porphyry intrusions
associated with large alteration footprints at Smart Creek and
Sunrise (Figures 1-4).

Findings from 2024 Exploration
Program
The Smart Creek project hosts significant
mineralization corresponding to at least 3 related styles of copper
and gold deposit models, including porphyry copper-gold (PCD; Smart
Creek and Radio Tower), carbonate replacement deposits (CRD;
Sunrise Mine and Smart Creek), structurally controlled epithermal
gold (Sunrise Mine), and exotic or remobilized copper deposits
formed by supergene processes (Smart Creek Exotic Copper Target;
Figures 1-4). With the exception of the copper potential at Smart
Creek, mineralization at Smart Creek is the result of
magmatic-hydrothermal fluid flow driven and focused by Eocene
intrusions and trapped by reactive Helena Formation carbonate-rich
metasedimentary rocks which ultimately produced the following
opportunities.
Target Opportunities
Smart Creek
PCD Target:
Drilling by the previous operators did not
attain target depth in the western margin of the Smart Creek area
which is characterized by 1) significant copper (and molybdenum)
soil anomalism, 2) a major induced polarization chargeability
anomaly (Figures 1-4). Hence, the Mo soil anomaly adjacent to the
extensive exotic copper has not been tested (Figure 2). Norden
Crown has reason to believe that the grades may be high due to 1)
the quality of the reactive carbonate host rocks (Helena
Formation), 2) widespread skarn, marble and quartz veins which are
consistent with the distal parts of a porphyry and 3) presence of
an unreactive cap rock aquitard unit (Missoula Group). Cap rocks
are known to increase grades in porphyry copper deposits by forcing
fluids into more reactive adjacent units. An analogous mineralized
system is the Resolution copper deposit (Arizona) where high grade
carbonate and diabase host rocks are “super-charged” due to fluid
flow channelized by unreactive quartzite5,6. This target at Smart
Creek is untested by drilling.
Radio Tower
Target:
A second porphyry copper opportunity has been
recognized in the south part of the Sunrise mine area (Figures
1-3). Norden Crown geologists have recognized intense marble
alteration outcropping in an area underlain by anomalous Cu-Mo-Mn
in reconnaissance soil data, as well as a strong IP chargeability
high in a historic single geophysical reconnaissance line (Figure
3). The dimensions of the target are 1000m by 1300m defined by the
alteration mapping, IP and limited soil data (Figure 3). The strong
marble alteration zone is flanked by more distal dolomite
alteration and the entire area is underlain by reactive Helena
Formation banded carbonates. The Robinson Mine, in Eastern Nevada
is an analogous magmatic-hydrothermal system and contains
high-grade ore hosted by chemically reactive carbonate host
rocks6,7.
Sunrise
Structurally-Controlled/Epithermal Gold:
Norden Crown geologists have evaluated rocks and
historic mine material in the Sunrise Mine area (Figures 1-3).
Alteration is characterized by vuggy silica associated with
silicified -clast breccia and strongly sulphidized host rocks.
Intense clay, limonite are the products of weathering of the
widespread sulfides. Sunrise Mine area is an opportunity to develop
targets with gold potential in the shallow porphyry environment,
distal to the porphyry centers identified at Smart Creek and
Sunrise South. Gold deposits commonly occur in structures and
stratigraphic traps within the distal and/or shallow extensions of
the porphyry environment.
Carbonate
replacement Targets (2+ target
areas):
Widespread marble and skarn alteration is mapped
at both Smart Creek and Sunrise (Figures 1-3). Leakage
characteristics in these rocks includes manganese oxides and copper
oxides in fracture surfaces cutting the dominant Helena Formation
host rocks. This is the distal signature of the CRD clan of
deposits which commonly occur in porphyry environments inside the
5km region surrounding the heat and fluid source.
Smart Creek
Copper Oxide Target:
The Smart Creek area is underlain by widespread
copper oxides/carbonates at surface outcrops/subcrops as well as
defined in RC drilling (Figure 1). This target area sits 1 km east
of the Smart Creek hypogene porphyry target defined by IP
chargeability and soil Mo and Cu (Figures 1 and 2). The dimensions
of the copper oxide body measure 900m by 400m (plan) and up to 75m
depth, defined by historic drilling (Figures 1-3). The direct
analogy for the copper footprint at Smart Creek is the recently
active Carlota mine in eastern Arizona (50 Mt @ 0.5% Cu6,8,9).
Exploration Plan
Initial work on the project will focus on
further evaluation of the best anomalous zones with targeted
mapping and sampling. Norden Crown plans to complete the following
work prior to finalizing the positions of the initial drill
holes:
Geological
mapping
Detailed alteration mapping is planned focusing
on zonation and alteration intensity as vectors to mineralized
centers. Constrain the position of drill holes.
LiDAR
LiDAR will be acquired for Smart Creek and the
Sunrise Mountain Area. These data will be used to constrain the
locations of historic workings and complete structural/geological
mapping which will allow Norden to focus on mineralized
structures.
Induced Polarization
Ground Geophysics (“IP”)
IP Geophysics will be used in and around the
Sunrise Mtn South area to further delineate the distribution of
sulphides in the target area which is characterized by intense
marble alteration of favorable Helena Formation carbonate host
rocks, as well as a 500m+ soil geochemical footprint.
Airborne EM
(electro-magnetic) Geophysics
Airborne EM geophysics will be conducted
property-wide and will contribute to targeting massive and semi
massive copper/gold bearing sulphides in carbonate replacement
geological environment.
Geochemistry
Norden intends to complete property wide
sampling of the limestone host rocks and evaluate the metal and
stable isotope signatures in limestones to vector toward targets
and identify any alteration that is not visible to the naked eye.
Norden will deploy ultraviolet (UV) evaluation of calcite veins to
establish whether they are related to hydrothermal fluids which
will also provide vectors toward mineralization. Infill soil
sampling in key target areas will be used to constrain the position
of the drill targets. Portable XRF sampling will be used in exotic
copper environments to vector toward the source of the fluids and
sulfide bodies.
The exploration work programs are planned to begin in H1 2025
with results expected prior to the Q3/Q4 drill campaign.
Notes
1 Composite intervals are calculated
using length weighted averages based on a combination of
lithological breaks and copper, gold, and silver geochemical assay.
All intervals reported are core lengths, and true thicknesses are
yet to be determined. Mineral resource modeling is required before
true thicknesses can be reliably estimated. Composite drill
intercepts are reported at minimum copper grades of 0.1% copper to
a minimum of 3.5 meters and include up to 3.5 meters of internal
dilution.
2 Data disclosed in this news release
includes historical drilling results and surface rock sampling
results as well as information derived from historic drill results.
Neither the Qualified Person (described below) nor Norden Crown has
undertaken any independent investigation of the sampling, nor have
they independently analyzed the results of the historical
exploration work in order to verify the results. Norden Crown only
considers these historical data relevant as the Company is using
this data as a guide to develop future exploration programs. The
Company’s future exploration work on the Project will include
verification of the exploration data by its Qualified Person.
3 There are a total of 38 surface rock
samples at Smart Creek. The copper grade in these samples ranges
from below detection limit to 5.64% copper with a mean value of
1.06% Cu.
