Frankfurt Trading Symbol: G6D2
VANCOUVER, BC, June 21,
2022 /CNW/ - Surge Copper Corp. (TSXV: SURG)
(OTCQX: SRGXF) (Frankfurt: G6D2) ("Surge" or the "Company")
is pleased to announce an updated mineral resource estimate ("MRE")
for its Ootsa Property, comprising pit constrained resources at
both the Seel and Ox deposits. This updated MRE is based on a drill
hole database comprising approximately 152,000 metres of diamond
drilling, including approximately 50,000 metres drilled since 2018.
The MRE combines multiple mineralized zones at the Seel deposit
area into a single pit constrained volume and demonstrates both the
overall size of the mineral endowment at Ootsa, as well as the
presence of near-surface, higher-grade subsets of the resource
which could be evaluated in future studies as potential starter
pits.
Highlights
- Combined Total: pit-constrained resources of
439 Mt grading 0.32% copper
equivalent* ("CuEq") in the combined Measured and
Indicated categories ("M+I"), representing a 96% increase in
M+I resources compared to the previous 2016 estimate, plus an
additional 138 Mt grading
0.28% CuEq in the Inferred category ("Inf."), comprised
of:
-
- Seel Deposit: 380 Mt grading 0.32%
CuEq M+I plus an additional 135
Mt grading 0.28% CuEq Inf.
- Ox Deposit: 59 Mt grading 0.32% CuEq
M+I
- Total contained metal in the M+I categories of 1.7 Blbs
Cu, 167 Mlbs Mo, 1.6 Moz
Au, and 30 Moz Ag
- With the nearby Berg deposit, which hosts 610 Mt of M+I resources, this new resource at
Ootsa brings Surge's total M+I inventory to over 1 billion
tonnes, with total contained metal across the two projects of
5.3 Blbs Cu, 586 Mlbs Mo, 1.6 Moz Au, and 89 Moz Ag
- Actively derisking advanced resources through metallurgical
testwork programs, long lead-time environmental monitoring, and
internal engineering trade-off studies, while pursuing further
discovery via drill testing and reconnaissance screening of over 20
regional exploration targets

Leif Nilsson, Chief Executive
Officer, commented: "Our objective with the drill campaigns in
2020-2021, and this resource estimate, were to determine the
characteristics of a "super-pit" resource at Ootsa that would
encompass various zones at Seel including the large mineralized
zone at West Seel, the near-surface gold-rich zone at East Seel,
and the high-grade Breccia Zone. This result demonstrates the
significant overall size of the Seel system and the flexibility
represented by the near-surface higher-grade zones, including the
Breccia Zone which has seen an approximate quadrupling in size and
remains open for further expansion. In a world that is starved of
developable large-scale copper resources in safe jurisdictions, the
Ootsa-Berg district is special due to its significant size
potential and proximity to world-class mining infrastructure. With
recent resource updates at both Ootsa and Berg now in place, and a
22,000 metre regional exploration program underway, we believe
there is strong potential to drive value through discovery and
continue to advance this premier Canadian copper district."
The Company is pleased with the significant gains achieved on
the Ootsa Property over the past two years of focused exploration.
This resource update has resulted in a 96% increase, compared to
the previous 2016 estimate, in the M+I categories on the Ootsa
Property and provides a solid foundation for advancing the project.
Figure 5 below shows the resource tonnage within the M+I categories
on the Ootsa Property by depth and highlights the presence of
near-surface, higher-grade subsets of the resource which could be
evaluated in future studies as potential starter pits. A technical
report for this MRE prepared in accordance with NI43-101 will be
filed within 45 days of this news release on SEDAR at www.sedar.com
and the Company's website.
Next steps at Ootsa involve ongoing advanced metallurgical
testwork, long lead-time environmental baseline monitoring
programs, internal engineering trade-off studies focused on
district-wide infrastructure options, and ongoing exploration. One
drill is actively turning at the West Ox target on the Ootsa
Property, and one additional drill is expected to arrive in late
June, before remobilizing to test targets in the northern portion
of the district (see Press Release dated June 1, 2022).

Notes:
1) Economic viability can only be assessed through the
completion of engineering studies defining reserves including PFS
and FS. Resource classification adheres to CIM Definition
Standards; it cannot be assumed that all or any part of Inferred
Mineral Resources will be upgraded to Indicated or Measured as a
result of continued exploration.
2) A C$8.27 per tonne NSR cut-off value was used as
the base case for reporting mineral resources that have reasonable
prospects for eventual economic extraction. The NSR cut-off was
derived from US$ metal prices of US$3.85/lb Cu, US$12.40/lb Mo,
US$1,750/oz Au, and US$22.00/oz Ag, and a USDCAD exchange rate of
0.77. Process recoveries used were 90% Cu, 70% Au, 70% Mo, and 65%
Ag with respective smelter payables of 96%, 90%, 98.5%, and 96%.
Refining charges in US$ were US$0.05/lb Cu, US$5/oz Au, and
US$0.50/oz Ag. A generated pit shell using Whittle (3DS Geovia) was
used to report resources. The generation of the pit shell
considered 45-degree slope angles, C$ operating costs of C$2.34/t
for mining and C$8.11/t for processing, G&A, and ore mining
premium with a 2% ore dilution rate.
3) Grades were estimated using ordinary kriging using
capped assays composited to two-metre intervals, with estimation
block sizes of 12x12x12 for both Seel and Ox.
4) Copper equivalent assumes metal prices of
US$3.85/lb Cu, US$12.40/lb Mo, US$1,750/oz Au, and US$22.00/oz Ag
and uses the formula CuEq (%) = Cu (%) + 3.2208 x Mo (%) + 0.6630 x
Au (g/t) + 0.0083 x Ag (g/t).
5) The total waste tonnes within the Seel constraining
pit are 1,443.4 Mt implying a strip ratio of 2.8 : 1, and the total
waste tonnes within the Ox constraining pit are 65.6 Mt implying a
strip ratio of 1.1 : 1.
6) Mineral resources that are not mineral reserves do
not have demonstrated economic viability.
7) The Qualified Person for the Mineral Resource
Estimate is James N. Gray, P.Geo, of Advantage Geoservices Ltd.
8) All figures are rounded to reflect the relative
accuracy of the estimate.
9) The effective date of the mineral resource estimate
is February 18, 2022.

Resource Estimation Methodology
& Parameters
Resource estimation was performed by James Gray of Advantage Geoservices Ltd., an
independent Qualified Person as defined by National Instrument
43-101. Data from 300 core holes at Seel and 133 at Ox was used for
estimation using Geovia GEMS software. Control for grade estimation
in both deposits is based on three directional domains and a 0.1%
CuEq mineralized domain. Mineralized versus background material was
separated using an indicator (0.1% CuEq) estimation method. Grades
were subsequently estimated by ordinary kriging inside and outside
that mineralized zone. Copper, molybdenum, gold, and silver grades
were estimated using capped assays composited to two-metre
intervals. The estimation block size was 12x12x12 metres for both
deposits. Average rock densities of 2.74 t/m3 and 2.70
t/m3 were applied to Seel and Ox, respectively, based on
4,081 measurements from Seel and 1,054 measurements from Ox.
Overburden was assigned a density of 2.0 t/m3.
Blocks were classified based on spatial parameters related to
available drill data as well as on the generation of an optimized
pit. At both deposits, Measured resource blocks have a maximum
nominal drill spacing of 40m and the
third closest hole is within 60m of
the block. Indicated blocks have a maximum drill spacing of
80m. Inferred blocks are the
remainder estimated within the pit volume. The resource was
constrained by a Whittle generated (3DS Geovia) pit for which the
optimization parameters used are included in Note 2 of Table 1.
Including 2% dilution the resource NSR cut-off is C$8.27/t.
Upcoming Catalysts
The Company anticipates updating the market on results from the
following activities:
- Results from the West Seel metallurgical testwork program
- Exploration updates throughout the 2022 field program
Quality Control
All drill core is logged, photographed, and cut in half with a
diamond saw. Half of the core is bagged and sent to ISO/IEC 17025
accredited assay labs in British
Columbia, while the other half is archived and stored on
site for verification and reference purposes. Gold is assayed using
a 30g fire assay method and 33 additional elements are analyzed by
Induced Coupled Plasma (ICP) utilizing a 4-acid digestion. Drill
hole assay samples are monitored through a quality control quality
assurance (QAQC) program that includes the regular insertion of
blanks, duplicates, and standards that are subsequently checked by
a qualified person to ensure proper quality assurance and quality
control. Jacques R. Stacey, P.Geo,
has worked on the Ootsa Property over the past two years and has
verified drilling procedures, drill hole locations, the drill hole
database, assay certificates, and QAQC results.
Qualified Persons
The Qualified Persons for the MRE are James N. Gray, P.Geo, of Advantage Geoservices
Ltd. and Jacques R. Stacey, MSc.,
P.Geo, of Northern Mountain Geosciences, both independent of the
Company and Qualified Persons as defined under National Instrument
43-101. James Gray is responsible
for the mineral resource estimate and Jacques Stacey has worked extensively on the
project, has visited the site, and has reviewed the drill hole
database, assay certificates, and quality control procedures. Both
Qualified Persons have reviewed and approved the technical
disclosure contained in this news release. The Qualified Persons
are not aware of any known environmental, permitting, legal,

Notes:
1) Copper Equivalent (CuEq) calculated using metal
prices of $3.10/lbs Cu, $10.00/lb Mo, and $20/oz Ag. Recoveries
were applied to correspond with estimated individual metal
recoveries based on limited metallurgical testwork for production
of a copper and molybdenum concentrate: supergene zone (Cu = 73%,
Mo = 61%, and Ag = 52%), hypogene zone (Cu = 81%, Mo = 71%, and Ag
= 67%), leachate zone (Cu = 0%, Mo = 61%, and Ag = 52%). Smelter
loss was not applied.
2) A cut-off value of 0.2% CuEq was used as the base
case for reporting mineral resources that are subject to open pit
potential. The resource block model has been constrained by a
conceptual open pit shell, however, economic viability can only be
assessed through the completion of engineering studies defining
reserves including PFS and FS. The CIM Definition Standards (May
10, 2014) were followed for classification of Mineral Resources. It
cannot be assumed that all or any part of Inferred Mineral
Resources will be upgraded to Indicated or Measured as a result of
continued exploration.
3) Dry bulk density has been estimated based on 2,996
in situ specific gravity measurements collected between 2007 and
2011. Values were applied by geology model domain (n = 18)
representing the weathering profiles and major lithological units;
values ranged from 2.38 t/m3 to 2.74 t/m3.
4) There are no known legal, political, unnatural
environmental, or other risks that could materially affect the
potential development of the mineral resources.
5) All numbers are rounded. Overall numbers may not be
exact due to rounding.

The Berg mineral resource estimate has been completed by Tetra
Tech in accordance with National Instrument 43-101 Standards of
Disclosure for Mineral Projects. The mineral resource estimate has
been prepared by Cameron Norton,
P.Geo., Independent Qualified Person as defined by National
Instrument 43-101, and has an effective date of March 9, 2021.
