- Numbers reflect rounding to nearest 1,000 tonnes and ounces.
- Mineral Resources are exclusive of reserves.
- Mineral Resources are not in the current mine plan and therefore do not have demonstrated economic viability.
- All Mineral Reserves and Mineral Resources estimates have been made in accordance with the Standards of the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) and NI 43-101 and assume a gold price of $1,750 (US$1,363) per ounce for the reserves and a gold price of $1,900 (US$1,474) per ounce for the resources, with a $1 USD → CAD exchange rate of $1.3).

Kiena Complex Resource Estimates as of December 15, 2020
Kiena Complex Mineral Resource Estimate by Area (2.8 g/t Au cut-off)
Please scroll to view more.
- These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
- The mineral resource estimate follows CIM definitions and guidelines for mineral resources.
- Results are presented in situ and undiluted and considered to have reasonable prospects for economic extraction, below 100m crown pillar.
- The estimation combined two (2) estimation methods, ordinary kriging in the Kiena Complex and polygonal for other deposits on the property.
- The Kiena Complex resources encompasses for 20 zones with a minimum true thickness of 3.0 m using the grade of the adjacent material when assayed or a value of zero when not assayed. High-grade capping varies from 20 to 200g/t Au (when required) was applied to composited assay grades for interpolation using an Ordinary Kriging interpolation method based on 1.0 m composite and block size of 5 m x 5 m x 5 m, with bulk density values of 2.8 (g/cm3). In addition, a high grade limit or second capping value was used for the second and third pass grade interpolation to restrict high grade impact at greater distance from the drill hole intersect. Indicated resources are manually defined and encloses areas where drill spacing is generally less than 25 metres, blocks are informed by a minimum of three drill holes, and reasonable geological and grade continuity is shown.
- The zone outside the Kiena Complex encompasses for eight (8) zones with a minimum true thickness of 1.5 metre using a polygonal estimation method. Indicated resources were estimated from drill hole results using the mid distance between drill hole or a maximum of 30 metres, 12.5 metres in some areas. The high-grade capping was fixed at 34.28 g/t Au with a bulk density values of 2.8 (g/cm3).
- The estimate is reported for potential underground scenario at cut-off grades of 3.0 g/t Au (> 40° dip) and 4.0 g/t Au (< 40° dip, Wesdome Zone). The cut-off grades were calculated using a gold price of US$1,300 per ounce, a CAD:USD exchange rate of 1.31 (CAD$1,700); mining cost $110/t (> 40° dip); $150/t (< 40° dip); processing cost $35/t; G&A $15/t. The cut-off grades should be re-evaluated in light of future prevailing market conditions (metal prices, exchange rate, mining cost, etc.).
- The number of metric tons and ounces were rounded to the nearest hundred and the metal contents are presented in troy ounces (tonne x grade / 31.10348).
- The QP is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue not reported in this Technical Report that could materially affect the mineral resource estimate.
The updated block model mineral resource estimate, proximal to Kiena Mine Development, was prepared by Karine Brousseau P.Eng. (OIQ #121871), Senior Engineer – Mineral Resources of the Company and a "Qualified Person" as defined in NI-43-101.The mineral resource estimate has been reviewed and audited by BBA Consulting, Toronto, Ontario. Pierre-Luc Richard P.Geo. (OGQ #1119) of BBA Consulting, is a "Qualified Persons" for the resource estimate as defined in NI-43-101 and is considered to be “independent” of Wesdome for purposes of NI-43-101.

- The Independent and Qualified Persons for the Mineral Resource Estimate, as defined by NI 43-101, are Pierre-Luc Richard, MSc, PGeo (InnovExplo Inc), and Carl Pelletier, BSc, PGeo (InnovExplo Inc), and the effective date of the estimate is February 8, 2013.
- These Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability.
- In-Pit results are presented undiluted and in situ, within Whittle-optimized pit shells. Underground results are presented undiluted and in situ, outside Whittle-optimized pit shells. The estimate includes 18 gold-bearing zones and 1 envelope containing isolated gold intercepts.
- In-Pit and Underground resources were compiled at cut-off grades from 0.3 to 5.0 g/t Au (for sensitivity characterization). A cut-off grade of 0.5 g/t Au was selected as the official in-pit cut-off grade and a cut-off grade of 2.0 g/t Au was selected as the official underground cut-off grade.
- Whittle parameters: mining cost = C$2.28; pit slope angle = 50.0 degrees; production cost = C$9.55; mining Dilution = 5%; mining recovery = 95%; processing recovery = 80% to 85%; gold price = C$1,500.
- A fixed density of 2.78 g/cm3 was used.
- A minimum true thickness of 5.0 m was applied, using the grade of the adjacent material when assayed or a value of zero when not assayed.
- Capping was established at 35 g/t Au, supported by statistical analysis and the high grade distribution within the deposit.
- Resources were evaluated from drill hole samples using the ID2 interpolation method in a multi-folder percent block model using Gems version 6.4. Based on geostatistics, the ellipse range for interpolation was 75m x 67.5m x 40m.
- The number of metric tons was rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations in Regulation 43-101.
- The pitshell used for the resource estimate extends slightly beyond the property limits in its northeastern portion. Although the entire resource lies within the property limits, some waste material outside the property limits will need to be removed to access some of the resource. Consequently, this portion of the pit may need to be re-considered in a future economic study.
- InnovExplo is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues or any other relevant issue that could materially affect the Mineral Resource Estimate.
