Radisson Announces Additional High-Grade Drill Results and Further Extends New Mineralization Beneath the Historic O'Brien Gold Mine
Radisson Announces Additional High-Grade
Drill Results and Further Extends New
Mineralization Beneath the Historic O'Brien
Gold Mine
Rouyn-Noranda, Quebec--(Newsfile Corp. - January 6, 2026) -
Radisson Mining Resources Inc.
(TSXV: RDS) (OTCQX: RMRDF)
("
Radisson
" or the "Company") is pleased to announce assay
results from six new drill holes completed at its 100%-owned O'Brien Gold Project ("
O'Brien
" or the
"
Project
") located in the Abitibi region of Québec. The six holes are the latest completed as part of the
Company's ongoing 140,000-metre step-out drill program designed to test the overall scope of gold
mineralization at the Project (see
Radisson news release dated October 16, 2025
). Two of the holes
represent the twelfth and thirteenth directional wedges completed from pilot hole OB-24-337 and serve
to expand the broad area of new high-grade mineralization being delineated across multiple veins
beneath the historic O'Brien Gold Mine. All six of the holes released today intersected gold
mineralization, and five of the holes returned intercepts with grades and thicknesses consistent with the
Project's existing mineral resources, continuing the very high success rate of the current drill program.
Highlights include:
OB-25-337W13
intersected 90.60 grams per tonne ("g/t") gold ("Au") over 1.0 metre within a
mineralized interval averaging 30.59 g/t Au over 3.0 metres
and
9.14 g/t Au over 2.7 metres,
including 16.35 g/t Au over 1.4 metres;
OB-25-337W12
intersected 25.10 g/t Au over 1.5 metres
and
14.20 g/t Au over 1.5 metres
and
11.40 g/t Au over 1.3 metres;
OB-25-322W2
intersected 3.11 g/t Au over 8.0 metres including 5.93 g/t Au over 1.5 metres
and
3.62 g/t Au over 4.0 metres including 6.33 g/t Au over 1.5 metres;
OB-25-322W1
intersected 4.02 g/t Au over 4.5 metres, including 8.29 g/t Au over 1.5 metres;
Matt Manson, President and CEO:
"Today we are releasing six new drill holes from our ongoing
deep step-out drill program at O'Brien. These continue to illustrate the extension of the Project's
system of gold mineralization below the historic O'Brien mine and the current mineral resources. Of
particular note are the two new wedges completed from pilot hole OB-24-337 located beneath the
former mine's final stope. These are the twelfth and thirteenth such wedges completed. Once again,
we are seeing multiple high-grade intercepts of quartz-sulphide veins within broader alteration
envelopes. This represents a system of gold mineralization that we have modelled as up to six veins
delineated over a 250-metre (east-west) by 500-metre (vertical) area that remains
open. With this
step-out drill program we are steadily pushing the limits of known mineralization at O'Brien outwards
and downwards. Overall, we have now completed 74 drill holes in the 140,000 metres program, 61 of
which have intersected mineralization with grades and thicknesses consistent with the Project's current
mineral resources, an 82% success rate. As we start 2026, we will be operating seven drill rigs at site
and ramping up to our eighth rig presently. Twelve additional step-out drill holes, including the final
OB-24-337 wedges, have been completed and are awaiting assays."

Notes on Calculation of Drill Intercepts:
The O'Brien Gold Project Mineral Resource Estimate effective May 6, 2025 ("MRE") utilizes a 2.20 g/t Au bottom cut-off, a US$2,000 gold price, a
minimum mining width of 1.2 metres, and a 40 g/t Au upper cap on composites. Intercepts presented in Table 1 are calculated with a 3.00 g/t Au
bottom cut-off. True widths, based on depth of intercept and drill hole inclination, are estimated to be 30-80% of core length. Table 2 presents
additional drill intercepts calculated with a 1.00 g/t bottom cut-off over a minimum 1.0 metre core length so as to illustrate the frequency and
continuity of mineralized intervals within which high-grade gold veins at O'Brien are developed. Lithology Codes: PON-S3: Pontiac Sediments; V3-
S, V3-N, V3-CEN: Basalt-South, North, Central; S1P, S3P: Conglomerate; POR-S, POR-N: Porphyry South, North; TX: Crystal Tuff; ZFLLC: Larder
Lake-Cadillac Fault Zone.
Gold Mineralization at O'Brien
Gold mineralizing quartz-sulphide veins at O'Brien occur within a thin band of interlayered mafic volcanic
rocks, conglomerates, and porphyritic andesitic sills of the Piché Group occurring in contact with the
east-west oriented Larder Lake-Cadillac Break ("LLCB"). Gold, along with pyrite and arsenopyrite, is
typically associated with shearing and a pervasive biotite alteration, and developed within multiple Piché
Group lithologies and, occasionally, the hanging-wall Pontiac and footwall Cadillac meta-sedimentary
rocks.
As mapped at the historic O'Brien mine, and now replicated in the modern drilling, individual veins are
generally narrow, ranging from several centimetres up to several metres in thickness. Multiple veins
occur sub-parallel to each other, as well as sub-parallel to the Piché lithologies and the LLCB. Individual
veins have well-established lateral continuity, with near-vertical, high-grade shoots developed over
significant lengths. Based on the historic data available, it is clear that the former mine was "high-
graded", with mining focussed on a main central stope and parallel veins identified but left undeveloped.
The historic O'Brien mine produced over half a million ounces of gold from such veins and shoots at an
average grade exceeding 15 g/t Au and over a vertical extent of at least 1,000 metres. Modern
exploration has focussed on delineating well developed vein mineralization to the east of the historic
mine, with additional high-grade shoots becoming evident in the exploration data over what has been
described as a series of repeating trends ("Trend #s 0 to 5").

Step-Out Drilling at O'Brien
Since the end of 2024, Radisson has been pursuing a program of broad step-outs beneath the historic
O'Brien Gold mine and the existing mineral resources designed to test the extent of mineralization at the
Project. This drilling is accomplished with pilot holes followed by wedges and directional drilling to
maximize drill efficiency. On October 16, 2025, Radisson announced the expansion of the step-out drill
program to 140,000 metres employing an eventual eight drill rigs.
The origin of the step-out drill program was the deep pilot hole OB-24-337, which was the first
exploration drill hole located below the former mine workings since mining ended in 1957. This hole
intersected 31.24 g/t Au over 8.0 metres, including 242.0 g/t Au over 1.0 metre at approximately 1,500
metres vertical depth (see
Radisson news release dated December 16, 2024
). With today's results,
assay results from a total of thirteen wedges from OB-24-337 have now been reported and up to six
gold-bearing veins have been delineated over an area of approximately 250 metres (east-west) by 500
metres (vertical). The thirteenth wedge, released today, intersected 9.14 g/t Au over 2.7 metres including
16.35 g/t Au over 1.4 metres within Piché rocks just 40 metres below the final historic mining stope
(Figures 1 and 3). The final two wedges, the fourteenth and fifteenth, have been completed and assay
results are expected shortly. Future drilling in this area will utilize new pilot holes and wedge extensions
to test the full scope of mineralization down to 2 kilometres depth.

Notes:
Hole lengths for wedges represent meterage from point of wedge. Drill hole OB-24-337 was completed in 2024 while its wedge branches were
drilled in 2025.
Today's results also include the first and second wedges completed from pilot drill hole OB-24-322,
which intersected high-grade mineralization on the downwards extension of Trend #1 at 1,280 metres
and 1,360 metres vertical depth, respectively. These two wedges appear to have intersected the same
mineralized zone over a vertical separation of 80 metres, returning similar intercepts of 4.02 g/t Au over
4.5 metres, including 8.29 g/t Au over 1.5 metres (OB-25-322W1) and 3.11 g/t Au over 8.0 metres
including 5.93 g/t Au over 1.5 metres
and
3.62 g/t Au over 4.0 metres including 6.33 g/t Au over 1.5
metres (OB-25-322W2). Additional drill wedges from OB-24-322 have been completed and assays are
pending.
Drill hole OB-25-371W7 is the seventh wedge from a pilot hole centered on the deep extension of Trend
#2. It returned three separate intercepts of gold mineralization that were short, but with grades and
thicknesses consistent with the Project's mineral resources, in an untested area on the western side of
Trend #2 towards the deep extension of Trend #1 (Figure 1). The Company considers the apparent
"gap" between the deep extensions of these two mineralizing trends to be a function of drill coverage
rather than mineralization (Figure 2). This area offers a significant opportunity to delineate future mineral
resources at relatively shallow depths and within the scope of the mine design contained in the Project's
2025 Preliminary Economic Assessment. Further drill testing here will be an important part of the
upcoming 2026 work program. The sixth drill hole release today, OB-25-377, was located in a gap area
between the western and eastern portions of the former mine and intersected three narrow zones of
minor mineralization.
QA/QC
All drill cores in this campaign are NQ in size. Assays were completed on sawn half-cores, with the
second half kept for future reference. The samples were analyzed using standard fire assay procedures
with Atomic Absorption (AA) finish at ALS Laboratory Ltd, in Val-d'Or, Quebec. Samples yielding a
grade higher than 10 g/t Au were analyzed a second time by fire assay with gravimetric finish at the
same laboratory. Mineralized zones containing visible gold were analyzed with metallic sieve procedure.
Standard reference materials, blank samples and duplicates were inserted prior to shipment for quality
assurance and quality control (QA/QC) program.
