Radisson SEDAR files NI 43-101 Technical report for the Updated O’Brien Resource estimate

Rouyn-Noranda, Quebec: Radisson Mining Resources Inc. (TSX-V: RDS, OTC: RMRDF) (“Radisson” or the “Company”) is pleased to announce it has filed on the SEDAR the independent NI 43-101 technical report (the “Report”) for the resource estimate update of the O’Brien gold project located along the Larder-Lake Cadillac Break (“L-L-C”) halfway between the two mining towns of Rouyn-Noranda and Val-d’Or, PQ. (See figure 2)

The report is available on SEDAR and on Radisson’s new website to the link below. The report supports Radisson’s opportunity of exploring and developing a high-grade gold project located along a major fault, within a world-renowned mining camp and host of a historical high-grade production (1,197,147 metric tons at 15.25 g/t Au for 587,121 ounces of gold from 1926 to 1957; InnovExplo, March 2018);

Press release highlights

  • The O’Brien gold deposit at a 3.5 g/t gold (“Au”) cut-off base case
    • 95% Increase for the Indicated resources totalling 233,491 oz grading 6.45 g/t Au
    • 3% Increase for the Inferred resources totalling 194,084 oz grading 5.22 g/t Au
  • The O’Brien project remains open below depth of 600 meters
  • Results from 29,787 m of drilling incorporated in the resource estimate update
  • The F Zone, contiguous and to the West of 36E area was not incorporated in the update, the Company evaluates the F Zone represents an excellent growth opportunity at O’Brien.

  • One drill rig currently in operation at O’Brien on a recently expanded 11,000 m drill program

O’Brien resource update – Substantial growth

The report filed today incorporates 29,787 of drilling completed at O’Brien in 2016 and 2017. A substantial conversion of Inferred ounces into Indicated ounces is shown in the report, including a 95% increase in Indicated resources at a 3.5 g/t Au cut-off. In parallel, the company was able to renew transferred Inferred resources, including a 3% increase. These results suggest that ongoing drilling at O’Brien could continue to have a positive impact on resources.

Notes to Accompany Mineral Resource Table:
1. The independent qualified person for the 2018 MRE, as defined by NI 43 101, is Christine Beausoleil, P. Geo, of InnovExplo Inc. The effective date of the estimate is March 20, 2018.
2. The Mineral Resources are classified as Indicated and Inferred Mineral Resources and are based on the 2014 CIM Definition Standards.
3. These Mineral Resources are not Mineral Reserves, as they do not have demonstrated economic viability.
4. Results are presented in-situ and undiluted.
5. Sensitivity was assessed using cut-off grades from 2.5 g/t Au to 5.0 g/t Au. The official in-situ resource is reported at a cut-off grade of 3.5 g/t Au. Cut-off grades must be re-evaluated in light of prevailing market conditions (gold price, exchange rate and mining cost).
6. A top cut of 30 g/t gold (5.0 g/t gold for the dilution envelope) was applied to assay grades prior to compositing grades for interpolation into model blocks using an inverse distance squared (ID2) method and was based on 0.75 m composites within a block model made of 3 m long x 3 m wide x 3 m high blocks.
7. Density data (g/cm3) was established at 2.75 g/cm3.
8. A minimum true thickness of 1.5 m was applied, using the grade of the adjacent material when assayed or a value of zero when not assayed for 17 different mineralised zones.
9. The number of metric tons and ounces was rounded to the nearest hundred. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations in Form 43 101F1.
10. InnovExplo is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issues that could materially affect the mineral resource estimate.

Next steps

As announced on April 24 2018, Radisson is pursuing the recently expanded 11,000 m drill program with main targets on:

  • The F Zone, excluded from current resources, thus, representing an excellent growth potential for the O’Brien project (4,000 m planned),
  • The near-surface vertical extension of the enrichment factor defined on 36E area through the historical drill core re-logging and assaying program (1,200 m planned).

Current work will allow the company to define a drill program below depth of 550 meters where all sectors of the O’Brien gold project remain open.
