Maple Gold Quebec Overview Map 002

The Douay Gold Project is located in Quebec, Canada. The Project is approximately 2.5 hours north of Val d’Or and 1.25 hours north of Amos via Highway 109. The pre-existing facilities are accessible via a gravel road less than 10 minutes from the main highway, while a new 75-person camp has been built just west of the highway.

Renowned for its mineral content, Quebec has a total area of 1.7 million km2, of which only 1% is mined and only 5% is covered by mining rights.

Quebec has a favourable business climate with over 200 mining companies working over 350 exploration & development projects (Investissement Quebec 2015); it is also the second most important province in Canada in terms of gold production.

Quebec offers a number of competitive tax incentives created specifically for mineral producers. Quebec's refundable tax credits, deductions and allowances make for a very friendly business climate with a combined tax rate for corporations of 26.8%, one of the lowest in North America.

The project benefits from existing infrastructure, which includes:

  • Hwy 109 leads to and cuts across the Project
  • Hydro-Powerline (Powerline 6) currently runs right through the Project
  • Full-service 46-person camp in place just west of highway 109
  • Core logging & storage facilities
  • Rail & Air within 55km (Matagami)

Fig. 1: General Geology of the Douay Project. Casa Berardi Fault Zone widens in Douay area, with North and South strands merging to the east and the west. Note syenitic bodies several km to NE and NW of the Resource Area along the north strand of the Casa Berardi Fault Zone.

The Douay Gold Project covers an area of more than ~390km² along the Casa Berardi Deformation Zone (“CBDZ”) within the prolific Abitibi Greenstone Belt (“AGB”). Douay belongs to the alkaline-intrusive-associated gold class of mineral deposits, which includes Beatty (>5.6Moz Au), Holt-McDermott (>1.3Moz Au), and Canadian Malartic (>17Moz Au) in the AGB.  The area is also prospective for the more typical AGB orogenic style (structurally controlled gold-quartz veins and veinlets) of gold deposit as well as for volcanogenic massive sulphide (“VMS”) deposits.

The Douay project is underlain by a northern assemblage of mafic and felsic pyroclastic and sedimentary rocks (Taïbi Grp), a central assemblage consisting of basalts, co-genetic gabbros with lesser felsic volcanic rocks (Cartwright Hills Grp) intruded by the 6.5 x 2km Douay alkaline intrusive complex (syenite to monzonite, alkali gabbro and carbonatite) with its associated gold mineralization; and a southern assemblage consisting mostly of basalts (also Cartwright Hills Grp) with siliceous-chemical sediments and chlorite-sulphide alteration zones that may be associated with VMS style of mineralization. The volcanic stratigraphy strikes WNW to ESE whereas the major regional fault zones trend E-W or NW-SE. Existing drill data shows multiple higher-grade zones, including Douay West, within and near the Douay intrusive complex.  In addition, there are further poorly explored known and possible syenitic bodies elsewhere on the property.

Fe-carbonate-albite-pyrite alteration assemblages may be associated with higher gold values, generally above 5 g/t gold. Fractured syenite containing irregular fine pyrite veinlets in addition to disseminated pyrite, encompassing altered basalt fragments and magnetite-rich zones typically yields 0.1 to 1 g/t gold or more over intervals from tens of metres to over 150m.


The new resource estimate (RPA 2019 - see press release October 24, 2019) integrates the Company’s new 3D geological and structural model to better constrain Douay’s nine mineralised zones. This work also includes several conservative adjustments with the aim of delivering a new mineral resource estimate that will focus infill and step-out drilling to optimize existing resources and advance the deposit toward the economic study stage. These adjustments and changes include (but not limited to):

  • Adjustments to the conceptual pit shell slope assumptions (less steep) with pit shells now also extending to shallower depths
  • Adjusted search ellipses with reduced projections between holes and from the last hole on the edge of any given mineralised zone
  • Updated capping methodology, levels and spatial restriction to control the influence of higher-grade samples
  • Improved bulk density modelling of individual geological domains

At a cut-off grade of 0.45 g/t Au for pit-constrained resources and 1 g/t Au for underground resources, the Douay deposit is estimated to contain Indicated Mineral Resources of 8.6 million tonnes at an average grade of 1.52 g/t Au, and Inferred Mineral Resources of 71.2 million tonnes at an average grade of 1.03 g/t Au (open pit + underground). See tables and figures below for more details:

1.      CIM (2014) definitions were followed for Mineral Resources.
2.      Mineral Resources are reported at an elevated cut-off grade of 0.45 g/t Au for open-pit Mineral Resources and a cut-off grade of 1.0 g/t Au for underground Mineral Resources.
3.      The Whittle pit shell used to estimate Mineral Resources used a long-term gold price of US$1,500 per ounce, however the implied gold price for the Mineral Resources reported at the elevated cut-off grade would be significantly lower.
4.      A US$/C$ exchange rate of 0.7, and a gold recovery of 90% were used.
5.      A minimum mining width of 3 m was used.
6.      Open pit resources are reported within a preliminary pit shell.
7.      Bulk density is 2.71 t/m3 or 2.82 t/m3 depending on the zone.
8.      Numbers may not add due to rounding.
9.      Mineral Resources for Douay have been updated using data available to October 23, 2019.

In addition to the reported resource, RPA has reported additional exploration potential (500,000 – 1,500,000 ounces) for the areas with known mineralisation below base of pit that were not included as inferred ounces (see Exploration Potential section below).

Underground Exploration Potential*

RPA has stated that the potential tonnage and grade of additional underground mineralisation below the new pit shells could be 10 to 30 million tonnes, grading between 1.5 g/t Au and 2.5 g/t Au for approximately 0.5 to 1.5 million ounces gold. Figure 2 shows the RPA reporting shapes in green (307,000 Inferred ounces averaging 1.75 g/t Au), as well as the mineralised blocks at various grades below the pit shells that were not included in the reporting shapes, therefore, not reported in the current Mineral Resource statement, due to insufficient drilling. The Company’s recent results from the single 531 Zone drill-hole during 2019 (included intercepts of 16m @ 4.58 g/t Au, 9m @ 4.92 g/t Au and 9m @ 4.71 g/t Au – see press releases June 5, 2019) demonstrate the exploration potential for further higher-grade mineralisation. The black ellipses in Figure 2 below highlight further exploration potential at depth.


Figure 2: NW-SE longitudinal vertical section view (all zones) showing distribution of below-pit shell underground blocks above 1 g/t Au cut-off. Only blocks within reporting shapes (green shaded area) form part of inferred underground Mineral Resource. Black ellipses point to undrilled exploration potential at depth, which is in addition to potential contributions from infill drilling in areas with current blocks

*The potential quantity and grade are conceptual in nature as there has been insufficient exploration to define a Mineral Resource along strike from the resource area, and it is uncertain if further exploration will result in the target being delineated as a Mineral Resource. The underground exploration potential estimated outside of the resource reporting pit shell is based on areas of mineralisation intersected by drilling, but not necessarily supported by two drill holes, which was required for Inferred Mineral Resources, plus the immediate down-plunge extension of known zones of mineralisation.
