Radisson exploration drilling suggests potential fourth high-grade mineralized trend, 1,200 m east of the old O’Brien Mine
Multiple intercepts including 31.56 g/t Au over 2.00 m and 13.83 g/t Au over 2.40 m
Key highlights
- Significant intercepts from exploration drilling along new high-grade trend #4
- OB-21-241: 31.56 g/t Au over 2.00 m including 60.80 g/t Au over 1.00 m
- OB-21-228: Multiple high-grade intercepts including,
- 13.83 g/t Au over 2.40 m including 29.30 g/t Au over 1.10 m
- 9.30 g/t Au over 1.90 m including 17.55 g/t Au over 1.00 m
- 5.66 g/t Au over 2.00 m including 10.35 g/t Au over 1.00 m
- OB-21-229: 5.14 g/t Au over 2.00 m and 5.95 g/t Au over 2.20 m
- OB-21-244: 4.03 g/t Au over 2.15 m and 4.70 g/t Au over 2.00 m
- New results along with historical drilling suggests a fourth potential high-grade mineralized vector (trend #4) approximately 1,200 m east of the old O’Brien Mine
- This sector does not contribute meaningfully to current resources. Drilling has traced mineralization down to a vertical depth of 330 m in this area which remains open for expansion over 750 m laterally and at depth.
- Significant intercepts from resource expansion drilling along high-grade trend #3
- OB-21-255: 15.68 g/t Au over 2.00 m including 25.10 g/t Au over 1.00 m
- OB-21-256: 11.75 g/t Au over 2.50 m including 24.30 g/t Au over 1.00 m
- Drilling to date has traced mineralization to a depth of 500 m in this sector where current resources are largely limited to a vertical depth of 240 m.
- 130,000 m drill program underway at O’Brien
- 116,000 m completed thus far with results pending for 34,000 m
- Cash balance of approx. $11.0 million
“In addition to targeting resource expansion along previously defined high-grade trends 1, 2 and 3, we are also stepping out to define additional O’Brien-like mineralized trends to the east of trend #3 and to the west of the historic O’Brien Mine. We are very pleased to report recent results including 13.83 g/t over 2.40 m (OB-21-228) and 31.56 g/t Au over 2.00 (OB-21-241) that appear to confirm a potential fourth high-grade mineralized vector further east of trend #3 and 1,200 m east of the old O’Brien Mine. Current and historical intercepts have now traced mineralization down to a vertical depth of 330 m in this sector that does not meaningfully contribute to current resources. In addition, drilling continues to highlight resource expansion potential along high-grade trend #3, with notable new intercepts including 15.68 g/t Au over 2.00 m (OB-21-255) and 11.75 g/t Au over 2.50 m (OB-21-256).
While results thus far cover only 1.2 km of strike to the east of the O’Brien Mine, today’s results re-affirm the potential upside from the more than 5 km of prospective strike that we control along the Cadillac Break. Results are pending from 34,000 m of drilling in 74 holes, of which 33 holes have visible gold occurrences. This includes an initial 5,700 m exploration drill program completed to the west of the O’Brien Mine and 28,300 additional meters completed on Trend 0, 1, 2 and 3. In addition, we are currently drilling high priority targets below previously encountered mineralization in trend #1 and #2. We expect a significant amount of news flows in the weeks and months ahead as these results become available.” commented Rahul Paul, President and Chief Executive Officer.

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 four high-grade mineralized trends, located approximately 300 m, 600 m, 900 m and 1,200 m respectively to the east of the old O’Brien Mine. Mineralized trends identified bear similarities with structures previously 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 expansion 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. We are currently drilling a series of deeper holes below 950 m in trend #1 and 800 m in trend #2, in order to test high potential targets at depth in these sectors. 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. While trend #4 does not materially contribute to current resources, drilling thus far has traced mineralization to a vertical depth of 330 m.
Results released thus far from the ongoing campaign cover a strike length of approximately 1.2 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.
116,000 m of drilling completed to date with results pending for approx. 34,000 m
This release represents approximately 5,391 m of drilling in 16 drill holes. Results are pending for approximately 34,000 m in 74 holes including 33 holes with visible gold occurrences. Released results to date (since the commencement of drilling in August 2019) represent approximately 63% of the 130,000 m planned thus far. The company remains well funded with approximately $11.0 m in cash as of December 31, 2021.

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 5 g/t Au were analyzed a second time by fire assay with gravimetric finish at the same laboratory. Samples 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.
