PRESS
RELEASE
Denison
Announces Discovery of
High-Grade Uranium Mineralization at Moon Lake
South
Toronto, ON – April 19,
2023. Denison Mines Corp. (“Denison” or the
“Company”) (DML: TSX, DNN: NYSE American) is pleased to
report that drill hole MS-23-10A intersected 1.38% eU3O8
over 8.7
metres (0.05%
eU3O8
cut-off), including a sub-interval
grading 2.88% eU3O8
over 3.1
m, intersected approximately 30
m above the unconformity in the Athabasca sandstone, as part of the
recently completed winter exploration program at the Moon Lake
South property (“Moon South”).
Uranium
mineralization was encountered in four of the six drill holes
completed during the 2023 winter exploration program, which was
designed to evaluate the strike length of low-grade mineralized
occurrences identified in the 2021 and 2016 drill programs. Figure
1 and Figure 2 depict the location of the Moon Lake South project,
and the significant drill results on the project to date,
respectively.
Andy Yackulic, P. Geo., Denison’s Director,
Exploration, commented, “The
discovery of high-grade uranium mineralization at Moon Lake South
gives further proof that the CR-3 trend has the potential to host a
large, high-grade unconformity-associated uranium deposit. The fact
that this high-grade material lies approximately 30 metres above
the unconformity contact is very encouraging – as perched
mineralization like this is typically only found proximal to
high-grade unconformity-hosted deposits.”
David Cates, Denison’s President & CEO
added, “The
discovery of high-grade sandstone-hosted uranium mineralization at
Moon Lake South is a very exciting development for Denison, as our
Company’s recent field testing at the nearby 95%-owned
Wheeler River project has illustrated the potential viability of
mining high-grade Athabasca Basin sandstone-hosted uranium deposits
via In-Situ Recovery (ISR) mining.”
2023 Moon South Winter Exploration Program Highlights
The
2023 winter exploration program consisted of six completed diamond
drill holes totalling 3,301 metres, designed to evaluate the
potential to expand the footprint of known mineralization
discovered in 2016 and 2021 by testing conductivity anomalies
identified from the 2022 stepwise moving loop electromagnetic (SWML
EM) survey.
Uranium
mineralization was encountered in four of the six drill holes
completed during the winter exploration program. The mineralized
intersections are summarized in Table 1.

The most significant mineralization was returned
from hole MS-23-10A, which intersected a broad zone of high-grade
mineralization grading 1.38% eU3O8
over 8.7 metres, associated with
strong grey alteration, located approximately 30 metres above the
sub-Athabasca unconformity. Given the limited number of drill holes
completed during the winter program, the mineralization discovered
in MS-23-10A remains open in multiple directions for future
follow-up.
Radiometric Equivalent Grades, Sampling, Analysis and Data
Verification
Following the completion of a drill hole, the hole
is radiometrically logged using a downhole gamma probe, which
collects continuous readings of radioactivity along the length of
the drill hole. Probe results are then calibrated using an
algorithm calculated from the comparison of probe results against
geochemical analyses in the area. The gamma-log results provide an
immediate radiometric equivalent uranium value
(eU3O8%)
for the hole, which, except in very high-grade zones, is reasonably
accurate. The Company typically reports eU3O8,
as a preliminary result and subsequently reports definitive assay
grades following sampling and chemical analysis of the mineralized
drill core.
Assay
sample intervals are generally 50 centimetres long, except where
higher or lower-grade mineralization boundaries fall within the
interval. In that case, two 25 centimetre samples are collected.
Flank samples of 1.0 metre are always collected where
mineralization is located. Systematic geochemistry samples are
collected every 10 metres down the hole.
All
assayed core is split in half, with one half retained and the other
sent to the Saskatchewan Research Council Geoanalytical Laboratory
in Saskatoon for analysis. Control samples are routinely assayed
with each batch of core samples analyzed.
About Moon Lake South
The
Moon Lake South project is a joint venture between Denison Mines
Corp., which holds a 75% interest in the property, and CanAlaska
Uranium Ltd., which holds the remaining 25% interest. Denison acts
as the project operator.
The
project lands are located in the southeastern part of the Athabasca
basin, approximately 12 kilometres southwest of Denison's Phoenix
deposit, and 30 kilometres northwest of Cameco’s Key Lake
Operation. The property is accessible year-round via the Fox Lake
tote road, allowing Denison’s exploration team to use the
nearby Wheeler River camp as a base of operations.
About Denison
Denison is a uranium exploration and development company with
interests focused in the Athabasca Basin region of northern
Saskatchewan, Canada. The Company has an effective 95% interest in
its flagship Wheeler River Uranium Project, which is the largest
undeveloped uranium project in the infrastructure rich eastern
portion of the Athabasca Basin region of northern Saskatchewan.
Denison's interests in Saskatchewan also include a 22.5% ownership
interest in the McClean Lake joint venture, which includes several
uranium deposits and the McClean Lake uranium mill that is
contracted to process the ore from the Cigar Lake mine under a toll
milling agreement, plus a 25.17% interest in the Midwest Main and
Midwest A deposits, and a 67.41% interest in the Tthe Heldeth
Túé (“THT,” formerly J Zone) and Huskie
deposits on the Waterbury Lake property. The Midwest Main, Midwest
A, THT and Huskie deposits are each located within 20 kilometres of
the McClean Lake mill.
Through its 50% ownership of JCU, Denison holds additional
interests in various uranium project joint ventures in Canada,
including the Millennium project (JCU 30.099%), the Kiggavik
project (JCU 33.8118%) and Christie Lake (JCU 34.4508%). Denison's
exploration portfolio includes further interests in properties
covering ~300,000 hectares in the Athabasca Basin
region.
Denison is also engaged in post-closure mine care and maintenance
services through its Closed Mines group, which manages Denison's
reclaimed mine sites in the Elliot Lake region and provides related
services to certain third-party projects.
