Douay Gold Project

Aurvista Local Map Sept 2017 05S

After a series of drill campaigns by multiple owners the project was acquired by Aurvista Gold Corporation from Vior Inc. in 2011. More recently, Aurvista invested in the reprocessing of ~130,000 metres of the historic drill-core and data to establish a more comprehensive and cohesive property-wide database. During Q3-Q4 of 2017, 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. Aurvista filed an updated resource estimate in April 2017 and has expanded the Douay Gold Project to now cover a 40+ km segment along the Casa Berardi Deformation Zone and total of 330+ km² within the prolific Abitibi Greenstone Belt.

  • Located in one of the best mining jurisdictions in the world (Quebec)
  • High grade gold lenses still intact and never mined
  • Large bulk tonnage gold model & established resource
  • Royalty free aside from 1% NSR that covers only a small fraction of the resource
  • Over 330km2 (33,000+ ha) property package with district scale discovery opportunities
  • Excellent infrastructure
  • Several large operating mines within 150km 
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 right to the Project
  • Hydro-Powerline (Powerline 6) runs right through the Project
  • Full-service 30 person camp
  • Core logging & storage facilities
  • Rail within 50km (Matagami)
project geology S

The Douay Gold Project covers more than 300 km², situated along the Casa Berardi Deformation Zone (“CBDZ”) within the prolific Abitibi Greenstone Belt (“AGB”). There are two distinct but overlapping geological signatures: a primary Volcanogenic Massive Sulphide (“VMS”) of Copper-Zinc affinities overprinted by a secondary structurally hosted gold system. The interpreted geological signature  is similar to the 15+ million ounce Doyon-Bousquet-Laronde Mining Camp located 100 km S-SW of Douay, along the Cadillac Larder Lake Deformation Zone.

Douay consists of a northern corridor of fairly pristine, well preserved volcanic tuffs of felsic to intermediate compositions; the central 3 km wide Douay-Style Mineralization (“DSM”) corridor hosting the CBDZ with a mix of 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 in a NW-W to E-SE directions whereas the gold structures trend E-W. There are at least a dozen of these subparallel structures. Management believes there are additional higher grade zones and are linked by an extensive network of E-W, NW-SE and NE-SW structures in magnetic iron rich volcanic rocks, but non-magnetic sulphide bearing, hosting iron-carbonates alteration, porphyries and/or silica-rich alteration and/or sodium-rich alteration.

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 multi-metric intervals. Fractured syenites containing fine fracture filling pyrite in addition to disseminated pyrite, encompassing altered basalt fragment and magnetite-rich "iron formation" contains 100 ppb to 1 g/t gold over decametric to hectometric intervals.

NI-43-101 Technical Report

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.
