TORONTO, Feb. 26, 2018 (GLOBE NEWSWIRE) -- Wesdome Gold Mines Ltd. (TSX:WDO) (“Wesdome” or “the Company”) is pleased to announce increased Mineral Reserves to 416,000 ounces of gold, net of depletion, (53,428 ounces) at its operating Eagle River Underground Mine located west of Wawa, Ontario. Mineral Reserves and Resources are updated as at December 31, 2017.


  • Mineral Reserves at Eagle River increased by 21% to 416,000 ounces of gold; grade increased by 32% compared to December 2016 (9.2 grams per tonne) to 12.2 grams per tonne gold in 1.059 million tonnes for 416,000 ounces (2016: 344,000 ounces)

Mr. Duncan Middlemiss, President and CEO commented, “In 2017, we successfully increased reserves net of depletion, and significantly improved the grade and reliability of our reserves through more tightly spaced definition drilling (35,000 metres). In January of last year, we made a very exciting new discovery within the 300 Parallel Zone - the 303 Lens, which so far consists of an average width of 8.2 metres grading 29.67 g/ tonne uncut. In May, we completed an exploration drift on the 844 metre Level, which enabled us to drill the structure up-plunge and is now traced from 750 metres depth to 1,000 metres depth and remains open above and below. As a result of this new discovery, the grade in the 300 Zone reserve increased by 49% over 2016. Production from this area began in late 2017. We also focused exploration efforts on the 7 Zone, increasing the grade by 44% and setting up production for 2018 to be in an area of longer strike lengths and greater widths than previously mined. Overall, the incorporation of these more recently discovered, higher grade zones into the current reserves has resulted in more ounces of gold in fewer tonnes thus improving the overall economics of the mine.”

“At Mishi, we are compiling data from approximately 30,000 metres of drilling conducted last year to the west of the Mishi open pit and expect to update reserves and resources for both this recent area of drilling and the immediate open pit area later in the year.”

Additionally, at the Eagle River mine, a total of 380 metres of new development is underway to provide drill platforms for the planned 25,000 metres of exploration drilling and 25,000 metres of definition drilling to better define and expand the current resource base at the high grade 303 East Zone up and down plunge, the 711 and 300 West Zones down plunge, and at various locations along the 8 Zone.

To date, the new parallel structures, namely Zones 300 and 7, have only been tested in the west end of the mine at depth.  The Company is planning an additional 5,000 metre surface drilling program to explore for additional Zones along these structures within the relatively untested areas of the eastern 2.0 km portion of the mine diorite. Exploration targeting is being aided with the creation of a comprehensive 3D geologic model that incorporates all recent and historic information to identify potential gold bearing structures and possible traps for gold along these structures.

*   Numbers reflect rounding to nearest 1,000 tonnes and ounces.
*   All Mineral Reserves and Mineral Resources estimates have been made in accordance with the Standards of the Canadian Institute of Mining, Metallurgy and Petroleum and National Instrument 43-101 and assume a gold price of $1,550CDN per ounce ($1240 USD) for the reserves and a gold price of $1,700CDN per ounce ($1390USD) for the resources. $USD/$CAD Exchange Rate of $1.20.
*   All Mineral Resources are in addition to Mineral Reserves.
*   Mineral Resources are not in the current mine plan and therefore do not have demonstrated economic viability.
*   At Eagle River high grade assays are capped between 60 – 140 g/t Au for individual zones based on grade frequency histograms at 95th percentile.
*   All Mineral Reserves at Eagle River employ a 1.5 metre minimum width, a 3.0 g/tonne Au minimum grade for continuity and include 1.0 metre of external dilution at 0.5 g/tonne Au. Mineral Resources are reported in-situ with no dilution provisions.
*   A 99% extraction factor was applied on the development reserves while a 90% factor was applied on the longhole stoping reserves.
*   The density used to calculate tonnage is 2.70 t/m3.

The Eagle River Mine is hosted by a 2.0 km by 0.5 km elliptical quartz diorite stock.  Mineralization is hosted by east-west, steeply north dipping laminated quartz veins.  The mine is serviced by a shaft and ramp system with the deepest mining level at 1,000 metres.

To date, the mine has produced 3,900,000 tonnes at an average recovered grade of 9.1 g/tonne Au, or 1,150,000 ounces of gold, over a 20 years mine life with the bulk of production coming from the main No. 8 vein structure.

In the summer of 2013, two new parallel structures were identified, the No.7 and No. 300 structures located approximately 200 m and 400 m north of the No. 8, respectively.  These have been aggressively explored and developed with the No. 300 Zone commencing production in 2015.

The following table provides a breakdown of Mineral Reserves and Resources by structure to illustrate the growing significance of these recent developments.

The mineral reserve and resource estimates reported in this news release were prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) as required by Canadian securities regulatory authorities. The United States Securities and Exchange Commission (the “SEC”) applies different standards in order to classify and report mineralization. This news release uses the terms “measured”, “indicated” and “inferred” mineral resources, as required by NI 43-101. Readers are advised that although such terms are recognized and required by Canadian securities regulations, the SEC does not recognize such terms. Canadian standards differ significantly from the requirements of the SEC. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories constitute or will ever be converted into mineral reserves. In addition, “inferred” mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource exists, is economically or legally mineable or will ever be upgraded to a higher category of mineral resource.
