Up 20% to 12.3 Mt grading 2.03 g/t for 805,000 Ounces of Gold
Toronto, Canada – November 1, 2017 – Savary Gold Corp. (TSX-V: SCA) (“Savary” or the “Company”) is pleased to announce an updated and increased Inferred Mineral Resource Estimate for its Karankasso JV Project in Burkina Faso totalling 12.3 million tonnes (Mt) grading 2.03 g/t gold for 805,000 ounces. The majority of the estimated Inferred Mineral Resources is comprised of open pit constrained Mineral Resources in six different zones using a 0.5 g/t cut-off grade and a small amount of underground Mineral Resources using a cut-off of 2.0 g/t that are situated beneath two of the open pit zones.
Highlights of the Inferred Mineral Resources Estimate:

Don Dudek, Savary’s President and CEO commented: “The program focused on expanding three of the six zones with the largest of the three, Diosso, returning 74% more pit constrained Inferred Mineral Resources compared to the 2015 Estimate. Mineralization continues to extend beyond pit-constrained limits at all zones. The new higher-grade underground Mineral Resource warrants further testing and expansion and are indicative of the upside potential of the project. Even with the increase in Mineral Resources, the methodology used to estimate the Mineral Resources was more conservative utilizing tighter mineralized envelopes and in estimating the potential Mineral Resource losses related to artisanal mining. We plan to continue to systematically expand the new and existing mineralized zones while exploring the remainder of the extensive mineralized corridor that transects the Project.”
The Karankasso Property (the “Property”) is located approximately 300 kilometres southwest of Ouagadougou, Burkina Faso’s capital city (see Figure), and 60 kilometres east of Bobo Dioulasso, the second largest city in Burkina Faso. The Property can be accessed by a paved highway with both rail and grid power coming within approximately 50 kilometres.
During the period from May 6, 2016 to July 4, 2017, 183 reverse circulation drill holes and 14 diamond drill core holes were completed on the Property for a total of approximately 23,170 metres of drilling. Approximately 72% of the holes were drilled to extend known zones with the remaining, testing and discovering new targets. For the current Mineral Resource, Savary compiled and interpreted the drill data to create an updated set of wireframes which where provided to P&E Mining Consultants Inc. for validation, refining and subsequent Mineral Resource estimation.
Mineral Resources have been estimated for six areas: Kien East, Kueredougou, Kueredougou West, Diosso (includes Diosso, Kueredougou West Trend and WTN zones), Karangosso and Serakoro 1 West, with all but one of the zones, in the northern half of the property (see Figure 1). Approximately 27% of the pit constrained Inferred Mineral Resources are oxidized saprolite and sap rock with the remainder of the Mineral Resources in fresh rock. The Kien East Zone is the largest of the six deposits containing approximately 3.8 million tonnes of pit constrained Inferred Mineral Resources grading 1.68 g/t totalling 204,000 ounces (see Figure 2). The Diosso South Zone area, is the second largest zone with estimated pit constrained Inferred Mineral Resources of 2.5 million tonnes grading 2.18 g/t gold totalling approximately 176,000 ounces. The Kueredougou Main Zone is the highest grade containing 0.6 million tonnes of estimated pit constrained Inferred Mineral Resources grading 2.51 g/t gold totalling 55,000 ounces (see Figure 3). The above Mineral Resources are at reported at a 0.5 g/t gold cut-off.
Resource Estimation utilized 3D constraining wireframes, capped 1m composites (capped between no capping and 20 g/t gold) and inverse distance cubed (1D3) grade interpolation.
Mineral Resource depletion, due to artisanal mining activity, was estimated for all zones using the following parameters:
Updated preliminary metallurgical test work indicates a range in estimated gold recoveries of 92 to 97% for oxide, 90 to 95% for sap rock and 80 to 91% for fresh rock (see Table 1). A summary of average and assumed recoveries is presented in Table 1. This summary represents only preliminary metallurgical data derived from a combination of timed bottle roll analyses of assay pulp composites over 72 hours to more rigorous grind and controlled gold extraction from both a bottle roll and CIL over a 48 hour period. Initial samples utilized assay pulps that were ground to 80% passing 75 microns. The latest tests utilized historic core and reverse circulation chips that were ground to 86% passing 80 microns. Six samples were ground to +94% passing 38 microns and demonstrated that gold recoveries can be improved by 2 to 7% with finer grinding. Some samples were noted to contain carbon but are considered anomalous or erroneous as the host rocks are dominantly intrusions and altered volcanics that should not contain any such carbon material. Additional metallurgical work, using fresh drill core samples will be utilized in the future studies.

|Diosso (WTN Zone)||92||90||80|
|Diosso (West Trend Zone)||92||90||80|
|Serakoro 1 West||97||95||91|
The mineralized zones are structurally-controlled and hosted by a variety of sediment, intermediate volcanic, potassic granite and diorite porphyry. Hydrothermal alteration minerals comprise a mixture of quartz vein, sericite, carbonate and pyrite with local fuchsite, arsenopyrite and tourmaline.
A summary of the of the pit constrained Inferred Mineral Resource Estimates, within a constraining pit shell, is presented in Table 2 with Mineral Resource Estimate details for each deposit, presented in Table 4. Cut-off grades at both, 0.5 g/t and 1.0 g/t, are presented with the Mineral Resource at a 0.5 g/t cut-off grade chosen as the base case. Optimized pit depths range from less than 90 metres for the Serakoro 1 West Zone to approximately 195 metres depth at the Karangosso Zone where locally higher grades have drawn the pit deeper with the rest of the pits dominantly being less than 100 metres deep.

*Notes on Open Pit Mineral Resource Estimation:
Underground Inferred Mineral Resources totalling 47,900 ounces grading 3.59 g/t contained within 415,000 tonnes were determined for two zones (see Table 3). Both zones have returned multiple intercepts of higher than average grade. At Kueredougou, intercepts containing from 48.00 g/t to 83.35 g/t gold intercepts over 4 metres occur in a structural intersection. At Karangosso, an intercept below the pit limits returned 6.73 g/t over 7 metres and 3.82 g/t over 13 metres.

Savary’s procedure for handling reverse circulation drill chips comprises initial riffle splitting of the rock chips from one metre drill length samples into approximately 2.5-kilogram samples, as well as description and logging into a database. A duplicate 2.5-kilogram sample, prepared at the same time as the assay sample, is kept as a reference for each sample. NQ-size core assay samples are first logged into a database and then are sawn in half with half of the core submitted for analysis; the length of the core samples depends on logged geological controls with samples varying from 0.3 metres to 2.0 metres in length. A sample duplicate and assay blank was inserted sequentially every 5 to 14 samples and an assay standard was inserted every 29 to 34 samples. This results in 8% of the assayed samples being reference/blank/control samples. Blanks and duplicates were preferentially inserted in visually mineralized zones to better test the assay results. This sampling procedure was periodically reviewed by Savary’s President and CEO, and the Company QP, Don Dudek, P. Geo. All assay samples were collected at site by staff from SGS Burkina Faso SA (‘SGS’) from Ouagadougou, Burkina Faso where sample preparation and analysis were performed. Each sample was dried, crushed to 75% passing 2 mm and then split to 1.5 kg by rotary splitter. This split was pulverized to 85% passing 75 microns. Fifty grams of the pulverized material was analysed for gold via fire assay with an atomic absorption spectroscopy (AAS) finish. SGS operates according to ISO 17025 standards and institutes a full Quality Assurance/Quality Control (QA/QC) program consisting of insertion of internal blanks, standard reference material, repeats and reject splits which in total account for up to 25% of all determinations conducted. All standards and blank control samples returned results within expected ranges.

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of Mineral Resources will be converted to Mineral Reserves. Inferred Mineral Resources have a lower level of confidence that that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.. Quantity and grades are estimates and are rounded to reflect the fact that the Mineral Resource Estimate is an approximation.
