Granada Gold receives updated pit-constrained Mineral Resources at Granada
ROUYN NORANDA, QC, Dec. 12, 2018 /CNW/ - Granada Gold Mine (TSXV: GGM) ("Granada Gold" or the "Company") is pleased to announce that the Company has received an updated Mineral Resource Estimate by SGS Canada for its 100%-owned Granada Gold Property near Rouyn-Noranda, Quebec.
The updated mineral resource calculation is accompanied by a revised Block Model for the entire area drilled at Granada as of the end of the 2017 drilling program.
Highlights:
- Pit constrained mineral resources:
- 464,000 ounces Measured @ 1.13 g/t Au and 349,000 ounces Indicated @ 1.13 g/t Au at a cut-off grade of 0.40 g/t Au (813,000 ounces M&I @ 1.13 g/t Au);
- 455,000 ounces Inferred @ 2.04 g/t Au
Granada is fully permitted for initial mining of open-pit resources based on a 2014 Pre-Feasibility Study, and mineralized material has been stockpiled on site.
Granada Pit Constrained Resources
Measured pit constrained mineral resources in the LONG Bars Zone are 12.8 million tonnes grading 1.13 g/t Au for total contained gold of 464,000 ounces. Indicated pit constrained mineral resources are 9.63 million tonnes grading 1.13 g/t Au for total gold ounces of 349,000, Measured+Indicated total 22.432 Mt @ 1.13 g/t Au for 813,000 ounces. Inferred pit constrained resources are 6.93 million tonnes grading 2.04 g/t Au for total gold ounces of 455,000.

Cautionary Statement
The historical production of 51,476 ounces of gold (181,744 sT @ 0.28 oz/sT Au) from 1930 to 1935 are included in the current resource statement as there is no digital information for exactly where the historical production was completed and if the historical production was completed in the area covering the current resource estimate. The historical production cannot be verified by SGS.
Notes to Mineral Resource Table
- Original assays have been capped at 32.5 g/t for calculation of the 1.5 m composites for the estimation of mineral resources.
- The density to convert volume to tonnage is 2.7 g/cm3.
- Gold recoveries are 95% for the full mill cyanidation of the whole mineralized material.
- Assumes gold price of $1,300 U.S/oz and exchange rate of $0.76US/$1 Can.
- The pit constrained resources were modeled on 5mE x 5mN x 5mZ block size.
- Block model extends to a depth of 120m from surface.
- Search ellipsoid estimation using ID2 grade interpolation for both Measured, Indicated and Inferred are: 30m x 30m x 7.5m, 60m x 60m x 15m and 100m x 100m x 15m respectively. Search ellipse orientation dipping north10 at 47 degrees.
- Classification: Minimum of 8 composites from 3 holes for Measured, Minimum of 8 composites from 3 holes for Indicated and minimum of 5 composites from 3 holes for Inferred using the above mention search ellipsoid dimensions.
- The database used for this mineral resource estimate includes drill results obtained from drill programs in 2009, 2010, 2011, 2012, 2016, 2017, trenches from 2014 and 2015 plus many of the historic holes (1990's) where sufficiently long sections of the drill core had been sampled and analyzed.
- The mineral resource statement includes the historical production of 51,476 ounces of gold (181,744 sT @ 0.28 oz/sT Au) from 1930 to 1935since there is no digital information for exactly where the historical production was completed and if the historical production was completed in the area covering the current mineral resource estimate.
- SGS 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.

About Granada Gold Mine Inc.
Granada Gold Mine Inc. (formerly Gold Bullion Development Corp.) is developing the Granada Gold Property near Rouyn-Noranda, Quebec. The property includes the former Granada gold mine which produced more than 50,000 ounces of gold in the 1930's before a fire destroyed the surface buildings. The highly prolific Cadillac Trend cuts through the north part of the property. The Cadillac Trend has been the source of more than 50 million ounces of gold produced in the past century on a line running from Val-d'Or to Rouyn-Noranda.
The Company has obtained all necessary permits for the initial mining phase known as the "Rolling Start" for which stripping has already begun, and has been conducting exploration drilling in order to expand the reported mineral resource for the property.
