Radisson intersects 10 g/t Gold over 1.2 meters and 3.4 g/t Gold over 5.1 m on the F Zone at the O’Brien gold project






Radisson Mining Resources Inc. (TSX-V: RDS) (OTC: RMRDF) is pleased to announce an update of the exploration program underway at the O’Brien gold project located along the Larder-Lake Cadillac Break, halfway between Rouyn-Noranda and Val-d’Or in Quebec, Canada.



Following the resource estimate update published for the O’Brien gold project (See March 20, 2018 Press release), the company announced the expansion of the drilling program to 11,000 meters with a principal focus on the F Zone located a few meters west of current resources.



Press release highlights:


  •  Hole OB-18-77 completed on the F Zone intersected;
  • 10 g/t Au over 1.2 meters at 300 m vertical depth
  • 4.3 g/t Au over 0.7 meters at 336 m vertical depth
  •  Hole OB-18-73 completed on the F Zone intersected;
  • 5.6 g/t Au over 1.4 meters at 210 m vertical depth
  • 3.5 g/t Au over 3.1 meters at 262 m vertical depth
  • 3.4 g/t Au over 5.1 meters at 312 m vertical depth
  •  3 shallow drill holes completed in vertical extension of the enrichment vector defined on 36E area are currently being assayed. 
  •  (See figure 1, figure 2 and figure 3)



Mario Bouchard, President and CEO comments: “Current results continues to highlight growth opportunities residing in the vicinity of current resources at the O’Brien gold project. The drilling program, 3D modelling of the F Zone and old O’Brien mine infrastructures will enable the company to increase gold resources significantly, at a very competitive cost and a few meters west of the bulk of current resources at O’Brien”. (See 3D longitudinal section)



F Zone area


The F Zone is contiguous and to the West of 36E area. Results obtained from the 2016-2017 drilling programs allowed to define the vertical and lateral extension of historical mined stopes on the F Zone (See 20.2 g/t Au over 2.5 m and 11.9 g/t Au over 3 m). Due to lack of 3D information from former mining infrastructures of the F Zone, this sector was not incorporated in the resource estimate update published on March 20, 2018. (See Radisson announces 95% increase in Indicated resources at O’Brien).



3D modelling of former mining infrastructures of the F Zone was completed in recent weeks. The geological team also established a 6,000 meters drill program (close to 2,000 m completed up to date) with main objective of building 43-101 compliant resources in a future resource estimate update for the O’Brien gold project.



The company is currently 3D modelling the mining infrastructures of the old O’Brien mine. This work will allow the company to increase its geological knowledge of the O’Brien project and to follow up on historic resources lying in this area of the project.

Note; Results are presented as down hole width; true width is estimated between 55 to 70% of down hole thickness.



Quality Assurance / Quality Control


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 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 program.
