TORONTO, Nov. 4, 2021 /CNW/ - QC Copper and Gold Inc.
("QC Copper" or the "Company") (TSXV: QCCU) is
pleased to announce the publication of the Technical Report for the
pit-constrained mineral resources estimate on the Opemiska Deposit
which the Company announced on September 20,
2021. The Technical Report is available on the Company's
website and SEDAR.
Highlights of Opemiska's Mineral Resource Estimate
Include:
- The Opemiska Deposit consists of 81.7M tonnes @ 0.88% CuEq of pit constrained
Measured and Indicated Mineral Resources and 21.4M tonnes @ 0.73% CuEq of Inferred Mineral
Resources.
- The Mineral Resource is pit-constrained and contains more than
532,000 tonnes or 1.17 billion lbs of copper and 816,000 ounces of
gold in the Measured & Indicated (M&I) classification and
an additional 109,000 tonnes or 240.0 million lbs of copper and
209,000 ounces of gold in the Inferred classification.
- Over 79% of the total Mineral Resource reports to the M&I
classification.
- Opemiska's initial Mineral Resource includes over 1.05 million
metres of drilling completed by QC Copper and former operators of
the Project. Significant drilling density and extensive records
from previous operators have supported a high-confidence Mineral
Resource.
- Within the larger Mineral Resource, the Company has identified
a high-grade potential starter pit of 10.6M tonnes of Measured & Indicated Mineral
Resources grading 1.26% CuEq.
- The Mineral Resources are pit constrained at a 0.2% CuEq
cut-off, inclusive of US$3.50/lb
copper and US$1,650/oz gold
prices.
- The Company has outlined multiple targets for expansion and
discovery drilling this coming winter. These targets include
extensional drilling to expand the existing Mineral Resource
envelope, proximal former mines including the adjacent Cooke &
Robitaille deposits, and other prospective targets along the
Gwillim and Beaver Lake fault zones.
A summary of the Mineral Resource Estimate is presented in Table
1, and the optimized pit shell is shown in Figure 1.

Mineral Resources
which are not Mineral Reserves do not have demonstrated economic
viability. The estimate of Mineral
Resources may be materially affected by environmental, permitting,
legal, title, taxation, socio-political, marketing, or other
relevant issues, although QC Copper & Gold is not aware of any
such issues.
|
2.
|
The Inferred Mineral
Resource in this estimate has a lower level of confidence than that
applied to an Indicated Mineral
Resource and must not be converted to a Mineral Reserve. It is
reasonably expected that the majority of the Inferred
Mineral Resource could be upgraded to an Indicated Mineral Resource
with continued exploration.
|
3.
|
The Mineral Resources
were estimated using the Canadian Institute of Mining, Metallurgy
and Petroleum (CIM), CIM
Standards on Mineral Resources and Reserves, Definitions (2014) and
Best Practices Guidelines (2019).
|
4.
|
All historical
underground excavations and stopes and vein envelopes were
digitized from scanned historical plans and
sections. A bulk density of 2.97 metric tonnes per cubic metre was
used for all resources except for the inferred in the
Springer pit where 2.94 was used.
|
5.
|
The Mineral Resource
reported here is based on a pit optimization. All interpolation
routines for the block model were
constrained by hard boundary domained halos constructed from the
sectional interpretation of the disseminated
mineralization surrounding the historical mined veins. Veins
were interpolated separately and stope volumetrics were
subsequently subtracted from the vein blocks to report the correct
tonnages and metal content of the residual high-grade
vein material.

Next Step: Drill to Expand the Initial Mineral Resources
Estimate
At this time, the Company is focused on expanding the initial
mineral resources estimate by drilling targets that could add
significant open-pit tonnage to Opemiska. A follow-up drill
program is currently underway that will complete 6,000 metres
before 2021 year-end, with a more extensive, multi-drill rig
program being planned for 2022.
Opemiska Infrastructure
The area has a rich history of mining and the resident
population is favorably disposed to mining activities and hosts
locally available skilled labour. The Opemiska Deposit is next to
the Town of Chapais with a
population of 1,609 (2019) and the Town
of Chibougamau with a population of 7,559 (2020) is located
approximately 40 kilometres to the east. Ample
electrical power is available from a nearby substation on the
James Bay powerlines which cross
QC Copper's land holdings. An operational rail line is
located within few kilometers from Chapais. Paved highways lead south to Lac
St-Jean and Quebec City and
southwest to Val d'Or and
Rouyn-Noranda. Finally, the
project is located in Quebec, the
most mining friendly jurisdiction in Canada and north of the 49th parallel and as
such is part of the Quebec
government's Plan Nord initiative and could benefit from special
fiscal and financial incentives.
About the Opemiska Copper Complex
The Opemiska Copper Complex is located adjacent to Chapais,
Quebec, within
the Chibougamau district. Opemiska is also within the
Abitibi Greenstone Belt and within the boundaries of the Province
of Quebec's Plan Nord, which promotes and funds
infrastructure and development of natural resource projects. The
Opemiska Property covers over 155 square kilometres and includes
the past producing Springer, Perry, Robitaille and Cooke mines,
previously-owned and operated by Falconbridge between
1953-1991. The project hosts excellent on-site infrastructure,
including a power station and direct access to Highway 113 and the
Canadian National Railway.
QP Statement
The technical information contained in this news release has
been reviewed and approved by Charles
Beaudry, P.Geo and géo., Director and Vice President
Exploration for QC Copper & Gold, and Eugene Puritch, P.Eng. of P&E Mining
Consultants Inc., both Qualified Persons, as defined in "National
Instrument 43-101, Standards of Disclosure for Mineral
Projects." Mr. Puritch is independent of QC Copper &
Gold.
All drilling performed by QC Copper and Gold was done using NQ
sized drill rods and holes were stabilized to minimized
deviations. All core is stored in Chapais in a locked yard. All pulps have
been preserved as well as mineralized rejects.
For the exploration undertaken by QC Copper & Gold, all
assay batches are accompanied by rigorous Quality Assurance
procedures that include insertion of standards and blanks and
verification assays in a secondary laboratory. Quality
Control results, including the laboratory's control samples, are
evaluated immediately on reception of batch results and corrections
implemented immediately if necessary. All drill collars in
2019 and 2021 were positioned in UTM coordinates and post-drilling
surveyed using differential GPS instrumentation. The
historical mine holes were surveyed on surface and underground at
the time of drilling by mine personnel using conventional surveying
methods. The collars for 2019 were oriented by compass but in
2021 accurate non-magnetic orientation of collars was achieved
using the gyroscopic Azimuth Aligner by Minnovare. Downhole
deviations surveys were done with Flex-it instrument by Reflex
instrument at 30m intervals, and all
erroneous azimuths caused by excessive magnetism were purged from
the database. A systematic bulk density measurement program
using the water displacement method was implemented to measure the
bulk density of all rock types. A total of 779 bulk density
measurements were done for the 2019 drilling program and an
additional 267 measurements were done in 2021. No bulk
densities are available for the vendor drill holes or for the
historical mine holes. A specific susceptibility measurement
protocol was also implemented to estimate the relative abundance of
magnetite in the Ventures Sill's variably magnetic rocks. A
focused optical and acoustic televiewer surveying program was done
at the end of the program to obtain correctly oriented structural
measurement.
For the Mineral Resource database, additional QAQC measures
included core duplicates. For the historical drilling assay
verification measures comprised core resampling for the holes
drilled by the vendor in 2010, 2015 and 2016 and for the historical
Falconbridge mine era drilling
where no core remains a total of 37 twinned holes were collared and
results compared with the assays from the mine. The results
of these measures confirm that the assays from the vendor period
are equivalent to QC Copper assays and that the mine era assays are
demonstrably equivalent for the range of values from the lower
detection limit up to about 2.0% Cu which represents over 90% of
the assays in the Mineral Resource database. Above this grade
the number of samples in the twinned data is small and the variance
is high such as to be difficult to compare datasets.
Nevertheless, for the bulk of the mine drilling the assays are
comparable to modern-day, QAQC controlled assays. After review of
available data, the assays undertaken by QC Copper as well as the
vendor and the mine are judged to be acceptable for the purposes of
estimating a Mineral Resource on the Opemiska Project.
