1. VG denotes the presence of visible gold
2. True widths estimated at 70% to 80% of core length. Unless otherwise relevant, primary intercepts
reflect minimum mining width (1.5 0 m true width) at a 5.0 0 g/t cut -off grade consistent with
assumptions used in the 2019 MRE.
3. Assay grades shown uncapped. A capping factor of 60 g/t Au was used in the 2019 resource estimate
4. Table includes only intercepts that meet 5 g/t Au cut-off and minimum mining width constraints used
in the 2019 MRE. For a full listing of drill results from current drilling program click here.
“We continue to be very encouraged by results from our ongoing campaign that validate
our lithostructural model and demonstrate the significant upside to currently defined
resources. Drilling thus far has suggested the potential to at least double the depth extent
of resources along three high -grade mineralized trends within an approximately 1 km
strike to the east of the old O’Brien Mine.
In addition, several shallow holes released today intersected high-grade mineralized
structures outside defined resource blocks in the upper 450 m along trend #2 and in the
upper 200 m along trend #3 , highlighting opportunities for resource growth in sparsely
drilled areas closer to surface. We are particularly impressed by results from Trend #3,
including 10.02 g/t Au over 4. 40 m in hole OB -21-207 aimed at expanding one of the
highest-grade resource blocks in the 2019 mineral resource estimate.
The majority of our work program thus far has been focused within a 1 km along strike to
the east of the historic O’Brien Mine, we believe there is significantly more upside to be
unlocked from a prospective land package that i ncludes more than 5 km of strike length
along the prolific Cadillac Break. Results so far, all support our theory of discovering and
expanding additional high-grade mineralized trends as we step out systematically further
along strike and deeper beyond the limits of drilling to date .” commented Rahul Paul,
President and Interim Chief Executive Officer.
Step-out drilling highlights resource growth potential up to 330 m below current
resources in trend #2 (600 m east of the old O’Brien Mine)
OB-21-202 intersected 8.20 g/t Au over 7.00 m at a vertical depth of approximately 440
m. This intercept along with s everal relatively broader intercepts (previously released)
from holes OB-20-124 (8.35 g/t Au over 6.00 m), OB-20-180 (18.42 g/t over 5.00 m), OB-
20-156 (11.32 g/t Au over 11.80 m), OB-20-156W2 (5.77 g/t over 7.10 m) and OB-21-201
(11.13 g/t Au over 10.70 m) suggest potential for wider mineralized zones (5 – 20 m wide)
between 400 – 700 m vertical depth , likely highlighting the impact of cross-cutting high-
grade mineralized veins.
Drilling has now traced mineralization down to a vertical depth of 800 m, in this sector
where most of current resources lie from surface down to 400 m depth. Mineralization in
trend #2 is currently open for expansion below 800 m as well as laterally to the east and
west.
Exploration drilling highlights resource growth potential along trend #3 (900 m east
of the old O’Brien Mine)
Drill holes OB-21-206 and OB -21-207 (10.02 g/t Au over 4.40 m) were designed as
resource expansion drill holes near one of the highest -grade resource blocks defined in
2019. These results add to high-grade gold intercepts obtained in 2020 in the sector in
hole OB-20-149 (45.86 g/t Au over 2.10 m, obtained 260 m below current resources) and
OB-20-146 (17.90 g/t Au over 2.15 m and 21.29 g/t Au over 2.00 m).
Newly released intercepts confirm resource expansion and exploration potential in the
sector where most of current resources lie from surface down to only 240 m depth.
Drilling at O’Brien continues to validate the litho-structural model while
highlighting resource growth potential laterally and at depth
Drilling to date has continued to define and expand three high -grade mineralized trends,
located approximately 300 m, 600 m and 900 m respectively to the east of the old O’Brien
Mine. Mineralized trends identified bear similarities with structures previous ly mined at
O’Brien down to a depth of 1,100 m (historical production of 587 koz grading 15.25 g/t).
Drilling so far has demonstrated continuity of mineralization well below the boundary of
defined resources in all three trends, which remain open for exp ansion laterally and at
depth. In trend #1, drilling has highlighted continuity of mineralization down to a vertical
depth of 950 m, while current resources are mostly limited to a vertical depth of
approximately 600 m. In trend #2, drilling has highlighted continuity of mineralization down
to a vertical depth of over 800 m, while current resources are mostly within 400 m from
surface. In trend #3, drilling has traced mineralization down to 500 m vertical depth from
surface. Current resources are mostly confined to within a vertical depth of 240 m.
Almost all drilling conducted as part of the ongoing campaign has been within a strike
length of approximately 1 km to the east of the old O’Brien mine, representing only a small
portion of more than 5.2 km of prospective strike that Radisson controls along the Cadillac
Break. Given current geological understanding, the ongoing validation of the litho
structural model, the company estimates there is strong exploration for additional high -
grade gold trends along the whole 5.2 km prospective land package on the prolific Larder-
Lake Cadillac Break.
87,470 m of drilling completed to date with assays pending for approx. 10,021 m
This release represents approximately 9,660 m of drilling in 19 drill holes. Released results
to date (since the commencement of drilling in August 2019) represent approximately 52%
of the 130,000 m envisioned to be complete d by the end of 2021. As of September 7,
2021, the company remains well funded with approximately $10.0 m in cash.
