PRESS
RELEASE
Denison Reports Financial and Operational Results for
2022,
Including Significant De-Risking and Regulatory
Milestones
Toronto, ON – March 9,
2023. Denison Mines Corp. (‘Denison’ or the
‘Company’) (TSX: DML, NYSE American: DNN) today filed
its Condensed Consolidated Financial Statements and
Management’s Discussion & Analysis
(‘MD&A’) for the year ended December 31, 2022. Both
documents will be available on the Company’s website
at www.denisonmines.com,
SEDAR (at www.sedar.com)
and EDGAR (at www.sec.gov/edgar.shtml).
The highlights provided below are derived from these documents and
should be read in conjunction with them. All amounts in this
release are in Canadian dollars unless otherwise
stated.
David Cates, President and CEO of Denison
commented, “Our results from 2022
reflect an incredibly successful year highlighted by significant
de-risking and regulatory milestones supporting the continued
advancement of our flagship Wheeler River
project.
We made history with the successful permitting, procurement,
construction, commissioning and operation of the Feasibility Field
Test (‘FFT’) facilities at the high-grade Phoenix
uranium deposit (‘Phoenix’) – where we achieved
the first known recovery of uranium bearing solution via in-situ
recovery (‘ISR’) mining in Saskatchewan’s
prolific Athabasca Basin region. The FFT was accomplished through
the tireless efforts of our Saskatoon-based technical team over the
past four years to systematically de-risk the use of ISR mining
through extensive field and laboratory testing programs. The highly
successful results of the FFT clearly demonstrate that the Phoenix
deposit is amenable to ISR mining and that the Company can move
confidently ahead with its plans to complete a feasibility study
for the project during the first half of 2023.
In parallel to our technical de-risking efforts, we achieved a
notable milestone in the permitting process for the planned Phoenix
ISR project with the submission of a draft Environmental Impact
Statement (‘EIS’), which follows from several years of
baseline environmental data collection, technical assessments, and
extensive engagement and consultation with Indigenous and
non-Indigenous interested parties. The draft EIS demonstrates that
the project can be constructed, operated, and decommissioned in a
manner that has fewer residual effects remaining after mitigation
than conventional open pit or underground mining and milling
operations – potentially achieving a superior standard of
environmental sustainability and re-shaping the future of uranium
mining in Saskatchewan.
I’m proud of the exceptional efforts of our growing and
highly motivated team to challenge the norm and achieve what others
may have previously considered impossible – with the result
positioning Denison as an industry leader on the cusp of deploying
the world’s lowest cost uranium mining method at one of the
world’s highest grade uranium deposits. Our timing is
excellent, as our success comes while we are observing sustained
improvements in both global sentiment towards nuclear
energy’s necessity in the battle against climate change and
the underlying uranium market.”
Highlights
■
Successfully completed 2022 ISR field work, including permitting,
constructing, and completing the leaching and neutralization phases
of the Feasibility Field Test at Phoenix
The
Company’s ambitious 2022 evaluation plan for the Wheeler
River project (‘Wheeler River’ or the
‘Project’) was designed to further de-risk the
technical elements of the ISR mining project planned for the
high-grade Phoenix uranium deposit. Central to this plan was the
FFT, which was designed to use the existing commercial-scale ISR
test pattern to perform a combined assessment of Phoenix’s
hydraulic flow properties along with the leaching characteristics
that have been assessed through the metallurgical core-leach
testing program. Overall, the FFT is intended to provide further
verification of the permeability, leachability, and containment
parameters needed for the successful application of the ISR mining
method at Phoenix.
During 2022,
the Company received approval to construct and operate a pollutant
control facility from the Saskatchewan Minister of Environment
(‘SKMOE’) and a License to Possess, Use, Store and
Transfer a Nuclear Substance (‘Nuclear Substance
License’) from the Canadian Nuclear Safety Commission
(‘CNSC’). With the receipt of these approvals, the
Company was fully permitted to operate the ISR FFT for Phoenix. The
Company completed the construction and commissioning of the
lixiviant injection system for the FFT and commenced the leaching
phase of the FFT in September 2022.
In November,
the Company announced the highlights of the highly successful
leaching phase, which:
●
Recovered approximately 14,400 pounds of
U3O8
over ten days of active leaching
following completion of initial acidification of the leaching
area;
●
Returned
maximum uranium head grade of recovered solution of 43 grams per
litre (‘g/L’) when the leaching phase of the FFT was
completed, with grades still rising (indicative of the ramp-up
segment of a well production profile);
●
Achieved
suitable acidification for ISR mining within 7 days post initial
injection at 5 metre well spacing (GWR-041) and within 17 days for
10 metre well spacing (GWR-038);
●
Demonstrated
the ability to achieve and maintain uranium mass flow rate
consistent with the assumptions in the Pre-Feasibility Study
(‘PFS’) prepared for the Project in 2018;
●
Further
demonstrated hydraulic control of injected solution during the FFT,
reporting no responses in the monitoring wells outside of the
designed FFT test area; and
●
Confirmed
breakthrough times between injection and recovery wells, consistent
with the Project's hydrogeological model and the previously
completed tracer test.
The Company
then successfully completed the neutralization phase of the FFT,
after which sampling of monitoring wells around the FFT site
confirmed the successful restoration of the leaching zone to
environmentally acceptable pH conditions, as outlined in the
applicable regulatory approvals for the FFT. The neutralization
phase was designed to confirm certain environmental assessment
assumptions and verify the efficiency and effectiveness of the
neutralization process planned for ISR mining at
Phoenix.
The final
phase of the FFT, which involves management of the recovered
solution, is expected to commence in the spring of
2023.
Other ISR
field work completed in 2022 included the installation of
additional test wells in multiple three-spot test patterns at the
Phoenix site in order to assess the ISR mining conditions in
additional areas of Phoenix, as well as the completion of extensive
hydrogeologic test work and a substantial borehole geophysics
program.
The results
of the FFT and additional test work completed in 2022 are expected
to inform and support the completion of the Feasibility Study
(‘FS’) initiated for Phoenix in late 2021.
■
Exceeded 97% recovery from long-term Phoenix ISR core leach
test
In December
2022, Denison announced the results from long-term core leach
metallurgical testing designed to support the establishment of ISR
production and recovery curves to be used in the FS. The Company
completed a long-term test of a representative intact core sample
(‘Core 4A’) using specialized equipment to replicate
the in-situ leaching conditions of the Phoenix
deposit.
The results
from long-term core leach testing of Core 4A were highlighted by
the following:
●
Overall
recovery of uranium in excess of 97% – demonstrating
excellent recovery of uranium from intact high-grade core, without
the use of permeability enhancement;
●
Average
recovered solution uranium head grade of 18.3 g/L – exceeding
the assumed 15 g/L uranium head grade being used in FS plant
designs (see news release dated August 4, 2021);
●
Continuous
intact core leach testing over a period of 377 days, with uranium
recovery head grades consistently maintained above 5 g/L during the
final stages of the production curve and then declining during the
ramp-down stage; and
●
Maximum
recovered solution uranium head grade of 49.8 g/L achieved using
similar lixiviant concentrations as to those used during the
FFT.
■
Achieved significant regulatory milestone for Wheeler River with
the submission of the draft EIS
In October
2022, Denison announced a significant regulatory milestone for
Wheeler River with the submission of the draft EIS to the SKMOE and
the CNSC. The EIS submission outlines the Company’s
assessment of the potential effects, including applicable
mitigation measures, of the proposed ISR uranium mine and
processing plant planned for Wheeler River, and reflects several
years of baseline environmental data collection, technical
assessments, plus extensive engagement and consultation with
Indigenous and non-Indigenous interested parties.
In November 2022, the Company announced that the
CNSC completed its conformity review of the draft EIS and
determined that the draft EIS met the requirements for the
advancement of the Environmental Assessment (‘EA’)
process. Denison also reported that the federal technical review of
the EIS, which is being completed under the provisions of
the Canadian Environmental
Assessment Act, 2012 (‘CEAA 2012’), had
commenced.
■
Executed agreements with Indigenous and
non-Indigenous communities of interest in the Athabasca
Basin
In 2022,
Denison entered into an exploration agreement with Kineepik
Métis Local #9 (‘KML’) and an exploration
agreement with the Ya'thi Néné Lands and Resources Office
(‘YNLRO’), Hatchet Lake Denesułiné First
Nation, Black Lake Denesułiné First Nation, Fond du Lac
Denesułiné First Nation (collectively, the 'Athabasca
Nations') and the Northern Hamlet of Stony Rapids, the Northern
Settlement of Uranium City, the Northern Settlement of Wollaston
Lake and the Northern Settlement of Camsell Portage (collectively,
the ‘Athabasca Communities’) in respect of
Denison’s exploration and evaluation activities within the
KML’s land and occupancy area and within the traditional
territories of the Athabasca Nations and Athabasca
Communities.
Each
exploration agreement expresses the respective parties’
intentions to build a long-term relationship and that Denison
wishes to conduct and advance its exploration activities in a
sustainable manner that respects the rights and interests of KML
and the Athabasca Nations’ Indigenous rights, advances
reconciliation with Indigenous peoples, and provides economic
opportunities and other benefits to the communities in an
authentic, cooperative and respectful way.
Denison also
entered into a participation and funding agreement with KML, which
expresses Denison's and KML's mutual commitment to co-develop an
agreement supporting the advancement of Wheeler River.
Finally,
Denison entered into a capacity and funding agreement with the
Métis Nation – Saskatchewan (‘MN-S’), which
expresses Denison’s commitment to ensure the MN-S’
participation in the regulatory process and associated documents
for Wheeler River.
■
Expanded high-grade uranium mineralization at McClean Lake
South
In September 2022, Denison announced that assays
received from exploration drilling completed at the Company's 22.5%
owned McClean Lake Joint Venture (‘McClean Lake’ or
‘MLJV’) during the winter of 2022 resulted in a
significant expansion of the high-grade unconformity-hosted zone of
uranium mineralization discovered in 2021 between the McClean South
8W and 8E pods (see news release dated April 14, 2021). Ten drill
holes completed during 2022 by Orano Canada Inc. (‘Orano
Canada’), 77.5% owner and operator of the MLJV, returned
notable uranium mineralization, including drill hole MCS-58, which
returned 2.96% U3O8
over 15.5 metres, including 24.49%
U3O8
over 1.5 metres, located approximately
54 metres to the southeast of drill hole MCS-34, which was
completed in 2021 and returned a mineralized interval of 8.67%
U3O8
over 13.5 metres. Overall, the results
from 2022 have successfully expanded the footprint of the
mineralized zone to approximately 180 metres in strike
length.
■
Intersected additional high-grade uranium mineralization at
Waterfound
In March 2022, multiple high-grade intercepts of
unconformity-hosted uranium mineralization were discovered in the
final three drill holes completed during the winter 2022
exploration program at the Orano Canada-operated Waterfound Joint
Venture (‘Waterfound’). The results were highlighted by
drill hole WF-68, which returned a broad zone of uranium
mineralization, including a peak interval of 5.91%
eU3O8
over 3.9 metres (0.05%
eU3O8
cut-off) with a sub-interval grading
25.30% eU3O8
over 0.7 m, located approximately 800
metres west, along the La Rocque conductive corridor, of the
previously discovered high-grade mineralization (including 4.49%
U3O8
over 10.53 metres) at the Alligator
Zone.
In September 2022, Denison announced that uranium
mineralization was encountered in three of the seven drill holes
completed during the summer exploration program at Waterfound,
highlighted by drill hole WF-74A, which intersected 4.75%
eU3O8
over 13.3 metres, including a
sub-interval grading 25.23% eU3O8
over 0.5 metres. The mineralized
intersection from WF-74A represents the best mineralized hole
drilled on the Waterfound property to date, and highlights the
potential for the discovery of additional high-grade uranium
mineralization further along strike to the west of the Alligator
Zone. Denison holds an effective 24.68% ownership interest in
Waterfound through its direct interest in the joint venture and its
50% ownership of JCU (Canada) Exploration Company Limited
(‘JCU’).
■
Completed the sale of 40,000 pounds of U3O8
from
MLJV production at a sales price of
$74.65 (US$59.25) per pound U3O8.
In April 2022, Denison completed the sale of
40,000 pounds of U3O8,
representing the Company’s share
of production from the SABRE test mining program completed by the
MLJV in 2021. The uranium was sold at a price of $74.65 (US$59.25)
per pound U3O8
for gross proceeds of
$2,986,000.
■
Obtained regulatory approval for the expansion of the McClean Lake
Tailings Management Facility
In January
2022, the CNSC approved an amendment to the operating license for
the MLJV and Midwest Joint Venture (‘MWJV’) operations,
which allows for the expansion of the McClean Lake Tailings
Management Facility (‘TMF”), along with the associated
revised Preliminary Decommissioning Plan (‘PDP’) and
cost estimate. The McClean Lake mill is a strategically significant
asset in the Athabasca Basin region and the approval of the TMF
expansion ensures the facility will be well positioned to serve as
a regional milling centre for current and future uranium mining
projects in the eastern portion of the Athabasca Basin for many
years to come.
As a result
of the updated PDP, the Company’s pro rata share of the
financial assurances required to be provided to the Province of
Saskatchewan decreased from $24,135,000 to $22,972,000.
Accordingly, in April 2022, the pledged amount of cash required
under the Company’s 2022 Credit Facility was decreased to
$7,972,000, and the additional cash collateral of $135,000 was
released – resulting in the return of $1,163,000 in
previously restricted cash to the Company.
■
Received US$4.8 million from Uranium Industry a.s
(‘UI’) pursuant to a Repayment Agreement
During 2022,
the Company received US$4.8 million from UI pursuant to the terms
of a Repayment Agreement (‘RA’) that was executed in
January 2022. Under the RA, UI has agreed to make scheduled
payments on account of an arbitration award in favour of Denison
(with respect to the arbitration proceedings between the Company
and UI related to the 2015 sale by Denison to UI of its mining
assets and operations located in Mongolia), plus additional
interest and fees. The total amount due to Denison under the RA,
including amounts already received in 2022, is approximately US$16
million, which is payable over a series of quarterly installments
and annual milestone payments ending on December 31,
2025.
