Radisson files NI 43-101 Technical report for the O’Brien Resource Estimate on SEDAR

Radisson Mining Resources Inc. (TSX-V: RDS, OTC: RMRDF): (“Radisson” or the “Company”) is pleased to announce the filing of a technical report titled, “Technical Report and Mineral Resource Estimate for the O’Brien gold project, Abitibi, Quebec“ (the “Resource Estimate”) with an effective date of July 15, 2019. The independent NI 43-101 technical report completed for the Company by 3DGeo-Solution includes the resource estimate 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.

The report is available on SEDAR and on Radisson’s website. 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; 3DGeo-Solution, July 2019);

Press release highlights:

New Mineral Resource Estimate

Using a 5.00 g/t Au cut-off grade, the current mineral resource estimate reports:

  • Indicated Resources of 949,700 tonnes at 9.48 g/t Au, for a total of 289,400 oz Au
  • Inferred Resources of 617,400 tonnes at 7.31 g/t Au, for a total of 145,000 oz Au

The New Mineral Resource Estimate is based on:

Large increases in contained gold ounces and average gold grades

The new mineral resource estimate has resulted in a large increase of contained gold oz per vertical meter as grade and contained ounces have increased across all categories at all cut-offs. (See table 1 below)

New Litho-Structural Model unlocks the “jewellery” box mystery of the high-grade O’Brien mine 

The new structural model has resulted in a much better comprehension of the O’Brien gold project, highlighting a strong compatibility with the historic data and geometry of the Old O’Brien mine, where only 3 veins returned 90% of the historic production at an average grade of 15.25 g/t Au.

New Litho-Structural Model unlocks Significant property wide Exploration Potential along strike and at depth (See O’Brien gold project longitudinal section)

Current mineral resource area is only defined to 550 metres depth. Two historical drill intercepts have returned 17.46 g/t Au over 1.00 m and 13.68 g/t Au over 0.32m below 1,000 m depths. Other mines in the area have exceeded depths well below 1,000 m. Current mineral resource area is adjacent to the old O’Brien mine where historic production reached a vertical depth of 1,100 metres and remains untested below.

High-priority resource expansion and exploration drill targets have been defined:

  • In vertical extension of the 36E and F Zones
  • Infill targets and in vertical extension of the Kewagama zone
  • On the Vintage Zone
  • Near surface on O’Brien West

Radisson Mining Resources Inc. (TSX-V: RDS, OTC: RMRDF) (“Radisson” or the “Company”) is pleased to announce the release of the New Resource Estimate for its 100% owned O’Brien gold project (“O’Brien”) located along the Larder-Lake-Cadillac Break (“L-L-C”), halfway between Rouyn-Noranda and Val-d’Or, in Quebec, Canada (See figure 1 and figure 2). The Mineral Resource Estimate was prepared in accordance with National Instrument 43-101 (“NI 43-101”) by independent consultant 3DGeo-Solution and is dated July 15, 2019. The F Zone, 36E and Kewagama zones of the O’Brien project are located within a 1.5 km corridor directly south of the L-L-C. The Vintage zone is parallel to and between 30 to 85 meters (“m”) north of the L-L-C.

  1. The independent qualified person for the current 2019 MRE, as defined by NI 43-101, is Kenneth Williamson, M.Sc., P.Geo, of Kenneth Williamson 3DGeo-Solution. The effective date of the estimate is July 15th, 2019.
  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 undiluted.
  5. Sensitivity was assessed using cut-off grades from 3.00 g/t Au to 7.00 g/t Au. Cut-off grade is function of prevailing market condition (gold price, exchange rates, mining costs, etc) and must therefore be re-evaluated accordingly.
  6. Base case cut-off grade of 5.00 g/t Au was established considering the narrow nature of the mineralized zones, a gold price of 1,350.00 US$/oz or 1,755.00 C$/oz using a 1.30 exchange rate, a recovery of 87.4%, a gold selling cost of 5.00 C$/oz, an overall mining cost of 67.50 C$/t, a processing cost of 65.00 C$/t and a G&A / Environmental cost of 32.50 C$/t.
  7. High grade capping of 60.00 g/t Au was applied to raw assay grades prior to compositing. Compositing length was established at 1.50 m. Interpolation was realized using an inverse distance cubed (ID3) methodology within a 3m x 3m x 3m cell-size block model.
  8. Density data (g/cm3) was set to 2.82 g/cm3 based on available density measurements.
  9. A minimum true thickness of 1.5 m was applied for the construction of the mineralized zones model, which consist of 63 different mineralized zones.
  10. Following recommendation of Form 43-101F1, the number of metric tons and ounces was rounded to the nearest hundredth. Any discrepancies in the totals are due to rounding effects.
  11. Kenneth Williamson 3DGeo-Solution is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issues that could materially impact the current Mineral Resource Estimate.

Kenneth Williamson 3DGeo-Solution considers the 2019 MRE to be reliable and based on quality data, reasonable hypotheses and parameters that follow CIM Definition Standards and that the results, presented undiluted, are considered to have reasonable prospects for eventual economic extraction.


20,000m Drilling program underway at O’Brien

Two drill rigs are now on site and running at O’Brien with approximately 20,000 meters to be completed by the end of January 2020. Radisson is working on increasing property wide resources by targeting the vertical extension below the 36E, F and Kewagama zones, and by further testing the Vintage Zone. The New Litho-Structural model also unlocked exploration targets on O’Brien West, located a few meters west of the old O’Brien mine. Part of Radisson’s strategy also includes infill drilling within volumes of high-grade inferred resource material where a potential for resource type conversion exists.
