RADISSON INTERSECTS 10 G/T GOLD OVER 1.2 METRES AND 3.4 G/T GOLD OVER 5.1 M ON THE F ZONE AT THE O’BRIEN GOLD PROJECT

.

Radisson Mining Resources Inc. has provided an update of the exploration program under way 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 metres with a principal focus on the F zone located a few metres west of current resources.

.

Press release highlights:

  • Hole OB-18-77 completed on the F zone intersected 10 grams per tonne gold over 1.2 metres at 300 m vertical depth and 4.3 g/t Au over 0.7 metres at 336 m vertical depth.
  • Hole OB-18-73 completed on the F zone intersected 5.6 g/t Au over 1.4 metres at 210 m vertical depth, 3.5 g/t Au over 3.1 metres at 262 m vertical depth and 3.4 g/t Au over 5.1 metres at 312 m vertical depth.
  • Three shallow drill holes completed in vertical extension of the enrichment vector defined on 36E area are currently being assayed.

Mario Bouchard, president and chief executive officer, comments: “Current results continues to highlight growth opportunities residing in the vicinity of current resources at the O’Brien gold project. The drilling program, 3-D 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 metres west of the bulk of current resources at O’Brien.”

.

F zone area

The F zone is contiguous and to the west of 36E area. Results obtained from the 2016 to 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 three m). Due to lack of 3-D 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-per-cent increase in indicated resources at O’Brien).

.

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

.

The company is currently 3-D 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.

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, Que. 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.
