Granada Gold Mine Inc. provided an updated High-Grade Mineral Resource Estimate of the Granada Gold Deposit using narrow, rich, vein modelling and both open pit and underground resources and revised pit optimization parameters which are based on the possibility of off-site custom milling ore rather than constructing and using an on-site mill. New drilling was achieved by GoldMinds Geoservices in 2020. While some of the results were still pending, SGS was mandated to create an updated resource estimation that shows both the potential for open pit resources and underground resources. In order to do that, the individual thin, rich veins had to be modelled individually. These veins are quite continuous (over distances of 800 m in strike and 900 m down dip). Mineralization is open at depth and on strike. The maximum distance between linked intervals is currently about 150 m. Some gaps of about 300 m have no drilling but should contain mineralization given the continuous nature of the deposit. The database used for this mineral resource estimate includes drill results obtained from drill programs in 2009, 2010, 2011, 2012, 2016, 2017, 2018, 2019, 2020 and trenches from 2014 and 2015 plus many of the historic holes (1990's). The thin, rich veins were modelled as a first step in the estimation process. A grade of 0.7 g/t over a length of 2.5 m was used as a minimum. While the 2.5 m constraint was always met, some intervals were considered under 0.7 g/t to allow to model continuous mineralized structures. The company estimate that the final 56 thin, rich veins modelled contain 88% of the gold from intervals that meet the 0.7 g/t over 2.5 m criteria. A large, low-grade zone was modelled around all intervals containing significant gold. This large, low-grade volume is similar in shape and size to the previous resource model. Composites of 2.5 m were created inside the thin, rich veins and in the low-grade volume. All resulting 57 volumes were estimated as hard boundaries. The rich, thin vein composites were capped at 21 g/t. It has a similar impact on gold content as the previous estimate capping methodology. The low-grade composites were capped at 7 g/t. A block model was created with blocks of 5 x 2.5 x 2.5 m to fill the rich, thin veins while using block centers as indicators for the block's nature. Both the kriging and inverse square distance estimation methods were tested with very similar results globally. The kriging is more conservative in grade and gold content once the company apply the cut-off grades to report resources. Kriging was retained as the estimation method of choice for this project. Search ellipsoids used for the estimation are of 30 x 30 x 7.5 m, 60 x 60 x 15 m and 100 x 100 x 30 m respectively. A minimum of a single drillhole is needed to estimate blocks inside thin, rich veins. A minimum of 2 drillholes are needed to estimate blocks in the low-grade volume. Search ellipsoid orientations are variable depending on local orientation of the model. The classification in measured, indicated and inferred was done as a separate step with an algorithm with ellipsoids centered on composites. A drilling grid with a minimum of 3 drillholes within 30 m of each other or less defines measured resources (under 25 m most of the time) and a drilling grid with a minimum of 3 drillholes within 60 m of each other or less defines indicated resources (under 50 m most of the time). Measured resource extends only by 20 m around drillholes and indicated extends only by 40 m. The mineral resource statement EXCLUDES the historical production of 51,476 ounces of gold (181,744 Tons at 0.28 oz/Ton Au) from 1930 to 1935. These numbers were subtracted from the measured resources in the whittle open pit.
