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:
The Douay Gold Project covers an area of more than 370 km² 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 corridor 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. 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 may yield 0.1 to 1 g/t gold or more over decametric to hectometric intervals.
The updated resource estimate (NI 43-101 Technical Report - March 2018) successfully converted a significant proportion of Inferred to the Indicated Resource category, at both Douay West and Porphyry Zones. Resources at Douay now stand at 2.76 million ounces Inferred plus 0.48 million ounces Indicated, as highlighted below:
Table 1: Douay Gold Project Pit-Constrained Indicated & Inferred Resource Summary (Base-case)
*See disclosure notes below
Indicated Resources are present in the more tightly drilled Douay West Zone (3,693,000 tonnes grading 2.47 g/t Au for 294,000oz Au) and also in four areas within the Porphyry Zone (5,690,000 tonnes grading 1.01 g/t Au for 185,000oz Au). The Indicated and Inferred Resources at various cut-off grades are summarized in Table 2 below.

*Comparison note: Micon 2017 estimate was all Inferred Resources of 2,813,000 ounces @ 1.05 g/t using a 0.5 g/t cut-off grade.

- Mineral resources that are not mineral reserves do not have demonstrated economic viability. Micon does not believe that mineral resources estimate is materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
- The quantity and grade reported includes both indicated and inferred resources for the Douay West and Porphyry zones and inferred resources for the remaining zones in the deposit. The inferred resources in this estimation are conceptual in nature and there has been insufficient exploration data to define these resources as an indicated category and it is uncertain if further exploration will result in upgrading them to an Indicated mineral resource category. There are no measured resources currently for the mineral zones comprising the Douay Project.
- The mineral resource estimate has been prepared without reference to surface rights or the presence of overlying public infrastructure.
- Figures may not total due to rounding.
- A gold price of US $1,400 per ounce was used for the purposes of demonstrating economics.
- The mineralized envelopes were re-modelled in GEMS at 0.3 g/t Au cut-off assuming an anastomosing style of mineralization with some inclusion of lower grade material for modelling purposes.
- Although the Douay West, Porphyry Zones were able to produce supporting variograms, all zones within the entire deposit were estimated using Inverse Distance Cubed.
- Search ellipses range from 50 m to 300 m using 3 passes to fill the model. The search ellipses were also optimized to reflect the anastomosing nature and different directions and dips within the mineralized zones.
- Block size of 10 m x 2 m x 5 m was used.
- The effective date of the mineral resource estimate is February 9, 2018.

The Douay Gold Project hosts numerous high-grade gold occurrences within larger low-grade envelopes of mineralization. Visible gold occasionally occurs in quartz micro-veinlets and the table below highlights some of the high-grade results reported from previous drill campaigns:

Exploration Upside & 2018 Winter Drilling Program
The Douay Gold Project not only hosts intrusive-related gold mineralization, but potentially also copper-zinc mineralization potentially of the volcanogenic massive sulphide (“VMS”) type, as well as orogenic gold vein systems. Gold mineralization hosted by altered mafic volcanic host rocks of the causative alkaline intrusive complex is generally of higher grade, occurring in zones such as Douay West (4.47 Mt @ 2.36 g/t Au; Micon, 2017), whereas gold hosted by altered, often porphyritic syenitic rocks forms larger lower-grade areas such as the Porphyry Zone (72.16 Mt @ 0.96 g/t Au; Micon, 2017). The Douay Resources are open along strike and plunge, such that brownfields exploration potential for resource expansion is considered excellent.
The greenfields portion of the Project (about 75% of the total area) remains relatively unexplored, despite its location along a major regional structure (Casa Berardi Fault Zone). This greenfields area is also considered to have potential for all three styles of mineralization mentioned above.
In 2017, the Company revised its exploration plans to capture both the brownfields and greenfields potential of the project. A thorough review and analysis of all existing geological, geochemical and geophysical data continues, which combined with new data generated from the current winter drill program as well as ongoing re-logging and sampling, will be used to refine the company’s comprehensive exploration strategy for 2018 and beyond.
