Douay Gold Project

Aurvista Local Map Sept 2017 05S

After a series of drill campaigns by multiple owners, the Douay project was acquired from Vior Inc. by Aurvista Gold in 2011. More recently, Maple Gold invested in the reprocessing of ~130,000 metres of historic drill-core and data to establish a more comprehensive and cohesive property-wide database. During 2018, the Company will complete the final 27,000 metres of re-logging and historic assaying and update the geologic model to support future targeting at the Project. Maple Gold filed an updated resource estimate in April 2017 and has expanded the Douay Gold Project to now cover a 55 km segment along the Casa Berardi Deformation Zone and with a claims total of 370 km² within the prolific Abitibi Greenstone Belt.

  • Located in one of the best mining jurisdictions in the world
  • Established gold resource (2.8M oz Au)
  • Royalty free except for 1% NSR that covers only 40k oz (NW Zone & small area of West Zone) of the current resource
  • Excellent infrastructure with large operating mines within 150km
  • District-scale 370km2 property package
  • 55 km of strike along the Casa Berardi Deformation Zone
  • Significant resource expansion and exploration upside

Near future exploration & upcoming catalysts

  • Selective re-logging, exploration and drill targeting results (Q4 2017)
  • 25,000 – 30,000 metres of drilling planned
  • Resource expansion and brownfields drilling (Q1 2018)
  • New greenfields discovery drilling (Q1 2018)
  • Updated resource estimate (2018)

location pic V2 S

The Douay Gold Project is located in Quebec, Canada. The Project is approximately 2 hours north of Val-d’Or via Highway 109 with the exploration camp accessible via gravel road less than 10 minutes from the main highway.

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 20 person camp with plans for 75-man camp by late December
  • Core logging & storage facilities
  • Rail within 50km (Matagami)

project geology S

Project Geology: 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 syenite-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.

Douay consists of a northern corridor of relatively well preserved tuffs of felsic to intermediate compositions, the central 3 km wide Douay-Style Mineralization (“DSM”) corridor enclosing the CBDZ, with a mix of syenitic porphyries, basalts, felsic volcanic rocks and iron formations, and gold-hosted shear zones, and a southern corridor of mostly basalts with siliceous-chemical sediments and chlorite-sulphide bearing feeder-pipes, both typical of VMS systems. The volcanic stratigraphy trends 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

an elongated body of syenite porphyry over an area of at least 6.5 x 2 km. In addition, there are further poorly explored known and possible syenite bodies elsewhere on the property.

Alteration assemblages and micro-fracturing in brittle rocks hosting narrow veinlets of quartz-carbonate with pyrite are associated with higher gold values, generally above 5 g/t gold over metric intervals within the DSM. Fractured syenite containing fine pyrite veinlets in addition to disseminated pyrite, encompassing altered basalt fragments and magnetite-rich "iron formation", yield 100 ppb to 1 g/t gold over decametric to hectometric intervals.

Notes:

1. The mineral resources above which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
2. The quantity and grade of reported inferred resources in this estimation are conceptual in nature and there has been insufficient exploration data to define these inferred resources as an indicated or measured category and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.
3. The mineral resource estimate and open pit optimization have been prepared without reference to surface rights or the presence of overlying natural constrains / public infrastructure.
4. The multiple open pit shells used are the ultimate-breakeven pit shell cones, which do not consider pit design or minimum mining width.
5. Figures may not total due to rounding.

exploration history S

The first gold discovery at the Douay Gold Project was made by Inco Ltd. in 1976. From 1976 to 2017 a total of ~222,000 metres of drilling has been completed, including ~66,000 metres by Aurvista (2011-2017), see the table below:

Company Year Drill Holes Total Metres Cumulative Drill Holes Cumulative Metres
Inco, SOQUEM and Aurizon 1976 to 1999 468 122,906 468 122,906
Vior 2004 to 2010 107 32,785 575 155691
Aurvista 2011 to 2017 182 66,142 757 221,833
 TOTAL 1976 to 2017 757 221,833    

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

This brownfields area at the Douay Gold Project contains two distinct styles of gold mineralization, as well as copper-zinc associated with volcanogenic massive sulphide (“VMS”) mineralization. Gold mineralization hosted by altered mafic volcanics 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 porphyritic rocks forms large lower-grade zones 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 remaining majority portion of the Project remains relatively unexplored, despite its location along a major regional structure. This greenfields area is considered to have potential not only for VMS and mafic- and porphyry-hosted gold mineralization, but also for other styles of mineralization such as occurs elsewhere along the CBDZ and in the region (i.e. Casa Berardi, Estrades, Eagle - Telbel, Vezza, and Sleeping Giant deposits).

The Company has 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 is in progress, which combined with generation of new data from re-logging and sampling programs (see figure), will be used to produce a comprehensive exploration strategy and diamond drilling plan during Q4 2017.
