stated, in this Annual Information Form (“AIF”): • Information is presented as of December 31, 2019; • All dollar amounts are in Canadian dollars, unless otherwise stated; and • References to “Wesdome”, the “Company”, “its”, “we”, “our” and other related terms refer to Wesdome Gold Mines Ltd. and its subsidiaries. Information of a technical and scientific nature that forms the basis of the disclosure in this AIF has been reviewed and approved by Michael Michaud, P.Geo., Vice President, Exploration of the Company, and Marc-André Pelletier, P.Eng, Chief Operating Officer of the Company, each of whom is a “Qualified Person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). TERMINOLOGY Certain abbreviations may be used in this AIF, as follows: Au: gold mm: millimetre g/t: grams per metric tonne kg: kilogram ozs: troy ounces g: gram t: metric tonnes t/m3: metric tonnes per cubic metre ha: hectare km: kilometre NSR: Net Smelter Return km2: square kilometre tpd: metric tonnes per day m: metre cm: centimetre mt: millions of metric tonnes DEFINITIONS Mineral Reserves Based on the CIM Definition Standards on Mineral Resources and Reserves (CIM Definition Standards) 2019. A mineral reserve is the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. Such study must include adequate information on mining, processing, metallurgical, economic parameters and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A mineral reserve includes diluting materials and allowances for losses that may occur when the material is mined. Mineral reserves are sub-divided in order of increasing confidence into probable mineral reserves and proven mineral reserves. A probable mineral reserve provides a lower level of confidence than a proven mineral reserve. Proven Mineral Reserves A proven mineral reserve is the economically mineable part of a measured mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic parameters and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justified. 3 Probable Mineral Reserves A probable mineral reserve is the economically mineable part of an indicated mineral resource and, in some cases, a measured mineral resource, demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic parameters, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. Mineral Resources A mineral resource is a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form or quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral resources are sub-divided in order of increasing confidence into inferred, indicated and measured categories. An inferred mineral resource has a lower level of confidence than that applied to an indicated mineral resource. An indicated mineral resource has a higher level of confidence than an inferred mineral resource but has a lower level of confidence than a measured mineral resource. Measured Mineral Resources A measured mineral resource is that part of a mineral resource for which quantity, grade or quality, density, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, underground workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.
