Radisson Mining Resources Inc. TSX-V: RDS has released the first set of results from the 6,000-metre continuing drilling program on the Vintage zone of the O’Brien gold project. The project is located along the Cadillac break, eight kilometres west of Agnico-Eagle’s Lapa mine, halfway between Rouyn-Noranda and Val d’Or in Quebec, Canada. The Vintage zone is parallel to and to the north of the bulk of current resources at the O’Brien project. The zone is located only 85 metres north of the Cadillac break in a context that is similar to historical mines in the Cadillac mining camp.
Mario Bouchard, president and chief executive officer, commented: “The significant results obtained within the 825 m strike of the Vintage zone are encouraging and continue to highlight the exploration potential of the sector.
“We await results from five drill holes that aimed the eastern extension of Vintage. The intercept of 6.9 grams per tonne gold over four metres obtained in a different geological setting at depth is of particular interest. This setting remains open in all direction and will require deeper drill holes in order to be tested. To this extent, the imminent completion of the resource estimate update and 3-D geological model of the O’Brien project will allow the company to define additional drill targets below the 600 m level, both on the Vintage zone and current resource area a few metres south. I must underline that current resource area also remains open at depth where one drill hole completed in 2004 returned 17.5 g/t Au over one m at 1,228 m depth.”
Press release highlights:
- Significant intersections reported are:
- 30.6 g/t Au over one metre at 436 m depth in hole OB-17-49W3;
- 11.6 g/t Au over 0.9 m at 336.2 m depth in hole OB-17-49W3;
- 17.0 g/t Au over 0.9 m at 211.5 m depth in hole OB-17-67.
- With the presence of multiple visible gold intercepts, the wedge holes (W1, W2, W3) completed from hole OB-17-49 are indicating:
- The vertical continuity and favourable geometry of the gold system on the Vintage zone, with presence of quartz veins, arsenopyrite and multiple visible gold intercepts;
- The deepest drill hole completed on the Vintage zone (OB-17-49) intersecting a sulphides-rich banded iron formation (10 per cent pyrite and 10 per cent pyrrhotite as opposed to arsenopyrite) which returned 6.9 g/t Au over four m; as expected, the wedge holes completed on this section intersecting the banded iron formation, but without the presence of pyrite, pyrrhotite and significant gold values. Up to date, this system remains open laterally and at depth.
- Assays are pending from five drill holes for approximately of 2,200 metres.
- The next two drill holes will be completed on the western actual boundary of the Vintage zone where hole OB-17-56 returned 27.5 g/t Au over 1.4 metres near surface.
DRILLING RESULTS SUMMARY ON THE VINTAGE ZONE Drill hole From To Length Grade Au (m) (m) (m) (g/t) OB-17-49W1 - - - - OB-17-49W2 319.5 320.6 1.1 5.7 and 340.1 341.0 0.9 6.4 and 354.5 356.0 1.5 4.4 OB-17-49W3 336.2 337.0 0.9 11.6 and 396.3 396.9 0.6 4.4 and 436.0 437.0 1.0 30.6 OB-17-63 - - - - OB-17-64 158.1 158.6 0.5 5.2 OB-17-67 211.5 212.4 0.9 17.0 OB-17-68 202.3 204.3 2.0 1.8 Note Results are presented as downhole width; true width are estimated between 55 and 70 per cent of downhole thickness.
Drill holes OB-17-65 and OB-17-66 aimed for geophysical anomalies defined in 2016 in the Pontiac sediments south of the O’Brien deposit. These drill holes did not intersect any significant gold value. Since focus of the actual drill program is on the Vintage zone, north of the O’Brien deposit DDH OB-17-65 and OB-17-66 where not included in the associated table.
Vintage zone exploration program
The Vintage zone is a parallel zone of the O’Brien project located approximately 85 metres north of the Cadillac break in the Cadillac group of metasediments comprising a sequence of polymictic conglomerate, banded iron formation (BIF) and grauwacke. In comparison, current resources of 36E and Kewagama zones are located in the Piche group, south of the Cadillac break. Due to their proximity, all zones could eventually be accessed via same mining infrastructures.
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 Swastika Laboratories Ltd., in Swastika, Ont. Samples yielding a grade higher than five g/t 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 and blank samples were inserted prior to shipment for quality assurance and quality control (QA/QC) program.

About Radisson Mining Resources Inc.
Radisson is a Quebec-based mineral exploration company. The O’Brien project, cut by the regional Cadillac break, is Radisson’s flagship asset. The project hosts the former O’Brien mine, considered to have been the Abitibi greenstone belt’s highest-grade gold producer during its production (1,197,147 metric tonnes at 15.25 g/t Au for 587,121 ounces of gold from 1926 to 1957; InnovExplo, April, 2015).
